The debt that Briffault speaks of is often referred to as though it should be taken for granted: The Arabs only transmitted Greek science and made no contribution to the overall history of Western science. Fortunately, many historians of science no longer hold this view. The Arabs “ under an Islamic hegemony “ acquired the scientific heritage of earlier civilizations, including classical Greece and Rome, and translated, preserved, and transformed much of it. Their scientific experience profoundly impacted the late medieval world of western Europe, where Muslim scientific achievements were important to the evolving Renaissance and the grand narrative of the history of science.

Until recently, these historic achievements were unknown. Gradually, more evidence showing the magnificent work in Islamic science has come to light. Modern history of science studies show that the productive, original scientific research of Muslim scientists persisted into the sixteenth century. Yet, histories of Islamic science consistently claim that such science declined after the eleventh century due to the opposition of religious authorities (e.g., Imam al-Ghazali), Islamic law, and the absence of a capitalistic economy,(2) to name just a few.

But this theory, in addition to its palpable counter-intuitiveness, fails to explain the growing body of evidence for the rise of science in the Islamic world after the eleventh century. This article will discuss just a part of the accomplishment, importance and originality of Islamic science between the ninth and sixteenth centuries.

Islamic science defined

The more historians deconstruct the grand narrative of their discipline’s history, the harder it becomes to assign linguistic, civilizational, and cultural adjectives to science.(3) Using such adjectives as Greek, Arabic, Chinese, Indian, Islamic, and more pertinently, western, in this context is quickly becoming obsolete, due to the newly-emerging understanding of the essentially hegemonic meanings such adjectives have always harboured.(4) These terms were often used as analytical categories that imparted some significance at the time when languages, cultures and civilizations used to embody individual characteristics that could distinguish them from one another.(5)

Now, however, such terms no longer serve the same functions, for the new scrutiny now being applied to such grand narratives of the history of science is making it quite obvious that these terms can no longer yield the same analytical results they used to yield.(6) In addition, such terms as culture, civilization, language, and science are no longer the same stable, commonly accepted terms of reference they once were,(7) since they embody ambiguities of their own and embody hegemonic theoretical structures that prohibit their modification with the old adjectives as was once done.(8) Furthermore, the intimate interconnectedness between scientific traditions makes it almost meaningless to speak of a Greek, Arabic or European science as if each had a character of its own.(9)

In light of the above, Islamic science (10) perhaps should mean science conducted mainly in Arabic and within the context of Islamic civilization, for many individuals from different ethnic and religious backgrounds were actively engaged in this undertaking: Christians (e.g., Hunayn ibn Ishaq), Persians (e.g., Ibn Nawbakht), Sabians (e.g., Thabit ibn Qurrah), and Jews (e.g., Masha’allah). Arabic was the main scientific, but not necessarily the native, language of these scientists. While the terms Islamic science and Arabic science are modern historical terms for the science conducted within the context of Islamic civilization, this science is Islamic in the sense that it suited the new and growing needs of Islamic civilization; was available entirely in Arabic, which had replaced Syriac; and was familiar to an increasing number of Muslim translators, students, and scientists./(11) It is in this context that Islamic science will be used in this article.

Of equal importance is the realization that Islamic science, in this context, does not imply religious sciences (e.g., jurisprudence) but rather the natural sciences (e.g., mathematics, astronomy, and physics). Nor does it imply the type of science that states that all knowledge, including scientific knowledge, can be found in the Qur’an.(12) This view examines the Qur’an’s scientific content and claims that, from relativity, quantum mechanics, big bang theory to the entire field of embryology and much of modern geology has been ˜discovered’ in the Qur’an.(13) Its adherents claim that scientific experiments have been devised to discover what is mentioned in the Qur’an but not known to science. Although this view is now the most popular version of Islamic science, it is not the one implied in this article.

Nor does it imply the mystical perspective that equates Islamic science with studying the nature of things in an ontological sense. In this viewpoint, the material universe is studied as an integral and subordinate part of the higher levels of existence, consciousness and modes of knowing.(14) Given such a context, science is not a problem solving enterprise and socially objective inquiry but more a mystical quest for understanding the Absolute.(15) This view also advocates the idea that in this universe, conjecture and hypothesis have no real place; all inquiry must be subordinate to the mystical experience.(16) Thus, its advocates view all science in Islamic civilization as sacred science, a product of a particular mystical tradition that traces its roots to the Greek neo-Platonists. This view, however, has been strongly refuted by Muslim historians of science (e.g., Ahmad al-Hassan) and Western historians (e.g., David King and Donald Hill).

Having said that, in this article Islamic science means any natural science that depends upon observation and experimentation, as well as rational thought in a critical way, that was studied by scientists of various religious and ethnic backgrounds who operated under an Islamic hegemony.

Islamic science remains largely unappreciated

With the exception of a few scholars, the contributions of Muslims scientists have been “ and remain “ poorly understood in the West. Western literature on Muslims presents them as mere torch-bearers of Greek science. This view is a product of Orientalism, which treats the Orient and Orientals as an ˜object’ of study inscribed by Otherness.(17) This typology is based on a real specificity but detached from history, and thus conceived as intangible and essential,(18) which, according to Ziauddin Sardar, the European man, from Greek antiquity onwards, becomes the measure of all men everywhere.(19) Accordingly, Muslim contributions to science were deliberately ignored or suppressed, and the view that Muslim scientists produced nothing original remained the orthodox belief until the mid-twentieth century.

In astronomy, for example, Kevin Krisciunas states that it is a common misconception that astronomical research fell into a dazed slumber following Ptolemy [the Greek scientist who lived during the second century], not to reawaken until the time of Copernicus.(20) Accordingly, Western historians of astronomy, like Neugebauer and Delamere, find nothing to report about Islamic astronomy.(21) The distinguished physicist-philosopher-historian Pierre Duhem (1861-1916), on the other hand, believed that: The revelations of Greek thought on the nature of the exterior world ended with the Almagest, (by Ptolemy) which appeared about A.D. 145, and then began the decline of ancient learning. Those of its works that escaped the fires kindled by Mohammedan warriors were subjected to the barren interpretations of Mussulman [Muslim] commentors and, like parched seed, awaited the time when Latin Christianity would furnish a favourable soil in which they could once more flourish and bring forth fruit.(22)

In other words, Muslims were fanatic, rampaging hordes, burners of Greek science, and also pale imitators, copiers of the Greeks.(23) Duhem also believed that: There is no Arabian science. The wise men of Mohammedanism were always the more or less faithful disciples of the Greeks, but were themselves destitute of all originality.(24) Ernest Renan (1823-92), the influential French philologist, believed that Islamic science could only flourish in association with heresy, and that science in Islam was merely parasitic on Greek culture and that Islam was simply a vehicle transmitting Greek philosophy to the Renaissance in Europe.(25) Other historians repeated the view that Muslim scientists acted as unproductive transmitters of Greek science. Von Grunebaum suggested that Islamic science was a mimic of Greek science, and asserted that Islam failed to put natural resources to such use as would insure progressive control of the physical conditions of life. Inventions, discoveries, and improvements might be accepted but hardly ever were searched for.”(26)

Prominent historians of Islamic science, however, explain that modern research in Islamic science poses a challenge to what is at best a caricature of history, one that portrays the ˜torch’ of science and knowledge as something that was handed down from the ancient Greeks to medieval Europe by way of Islamic scholars.(27) The danger of this representation is that it miscasts the role of the Islamic civilisation in the scientific revolution and undermines the often deep relation between cultures and intellectual movements.(28) Furthermore, it allows historians of classical science to conclude, science as theory is Greek and as experimental method it was born in the seventeenth century,29 thereby neglecting the contributions of Muslim scholars in between.

According to the torch theory, therefore, Islamic science constituted an excavation site, in which the historian is the archaeologist on the track of Hellenism.30 This approach, explains Rashed, has frequently ended up misrepresenting the results of Greek science as well as those of the seventeenth century, a necessary distortion if one wishes to link the two ends of the chain in a continuous history; on the other hand, and not without coincidence, it has led to some famous blunders affecting not only interpretation but comprehension too.(31)

Recent scholarship, however, confirms that Muslim scientists were more than just torch-bearers of Greek science, and that, in fact, they influenced the Renaissance. For example, in his The Middle East, Bernard Lewis explains that Greek science, on the whole rather tended to be theoretical. Medieval Middle Eastern [Islamic] science was much more practical, and in such fields as medicine, chemistry, astronomy and agronomy, the classical heritage was clarified and supplemented by the experiments and observations of the medieval Middle East.(32)

Today there is sufficient information about the quality and staggering quantity of Islamic science. Muslim scientists were active in many fields, from astronomy to zoology, and made original contributions. For example, recent research in astronomy shows that the mathematical models of Ibn Shatir, a fourteenth-century scientist, and the work of astronomers at the famous observatory in Maragha, laid the foundation for the Copernican revolution.(33)

Thus the novelty of Islamic science was that it was not the fruits of chance meetings, but the deliberate results of a massive movement of scientific and philosophical translation, undertaken by professionals “ sometimes rivals “ supported by power and stimulated by the research itself.(34) This movement resulted in the creation of a library on the scale of the world of its time.(35) Hence, for the first time scientific traditions from different backgrounds and languages became elements of one science, whose language was Arabic, and found ways of reacting together to engender new methods and sometimes even new disciplines, such as trigonometry, algorithms, and algebra.

Nevertheless, most people remain unaware of the importance of Islamic science. For example, most Westerners know that the Muslims invented algebra, Arabic numerals, and possibly the zero, but not that Islamic science is a possible concept.(36) Thus the most widely used American university textbook for the history of science (37) shows no interest in Islamic science per se and ignores most of the research on Islamic science conducted during the past 50 years.(38) Europe has no such textbook at all, and the less said about modern Arabic books on Islamic science the better.

Only recently has the Western scholarly community produced a substantial amount of reliable literature on the subject, some even for the general reader. For example, the Dictionary of Scientific Biography (1970-80) contains a series of articles on the major Muslim scientists, as does the Encyclopaedia of the History of Arabic Science (1996).

The contributions of Muslim scientists are even less well understood in the Islamic world itself, let alone elsewhere in the world. No serious modern work of a general nature on Islamic science is available in Arabic, except George Saliba’s The Origin and Development of Arabic Scientific Thought (1998). Also, very little of the research of the past 50 years is available or even known in the Muslim world.

According to King, the surviving written works and artefacts relating to the achievements of Muslim scientists are some 10,000 manuscripts preserved in libraries around the world, and some 1,000 instruments preserved in museums and private collections. (39) This is an insignificant number when compared to some of the libraries that existed during Islamic civilization’s golden age, when there were about 500,000 such manuscripts on their shelves. Few of the surviving major scientific works have been translated, and modern scholars have never read thousands of these manuscripts. Simply put, the history of Islamic science as a field remains virgin territory. Nevertheless, as little as we know about Islamic science, scholars affirm that every single specialised science in the West owes its origins to the Islamic impulse “ or at least its direction from that time on.(40)

Original contributions and their impact on modern science

Islamic science made many important contributions to the history of European scientific thought. Its importance can be deduced from its original contributions and impact. Islamic science influenced the sciences of the West, and thus had a direct influence on the Renaissance and the scientific revolution.

In the twelfth century, the West discovered, via a translated catalogue of sciences (map of knowledge) by al-Farabi, the existence of a considerable body of Antiquity’s scientific work. The West started examining these sciences, including astronomy, biology, botany, mathematics, and medicine. In addition, the medieval European university became the institutional manifestation of al-Farabi’s map of knowledge. In fact, the translated work of Islamic knowledge formed the basis and the scientific foundation of the university in its living reality “ the reality of its syllabus, the content of its teaching.(41)

The originality of Islamic science and its significant innovation is clear in several fields, including mathematics, astronomy, and medicine. Due to this topic’s vastness, this article shall confine itself to these three fields.

Originality in mathematics

Recent research proves that many of the ideas that once were thought to belong to European mathematicians of the sixteenth, seventeenth, and eighteenth centuries were in fact originated by Islamic mathematicians. In many respects, the mathematics studied today is far closer in style to that of the Muslims than of the Greeks.(42)

In the case of mathematics, Muslims initially were transmitters of almost all the important mathematical ideas of Mesopotamia, Egypt, Greece, India, Persia, and the Hellenistic world. But they also made original contributions that directly influenced arithmetic, geometry, algebra, and algorithms. Before learning of Indian numerals and the dust-board system early in the eighth century from Indian and Persian sources, the Muslims used finger computation, also called the arithmetic of the scribes or secretaries because it was used by government bureaucrats. This Indian system could express any number by using only 10 figures, including an empty place for zero, and the results were written out in words. (43) Though this system was far easier than, and superior to, the Babylonian sexagesimal system (in which letters replaced numbers), the latter system was still being used especially by astronomers. While the Babylonian system was developed for practical business needs, the Indian system was inspired by the Hindus’ inherent philosophical bent.

The Muslims recognized the importance of the Indian system and thus transformed it into the well-known Arabic numerals. This system, still used today in the West, enabled the West to achieve great breakthrough in mathematics. Arabic numerals became an intensely workable code, one so simple that literally any child can handle it, so flexible that in the hands of the mathematicians it became a vocabulary by which the most complex relations between the most astronomical quantities can be expressed. It was a revolution on a par with the invention of the computer; one was able to reduce the cosmos to a system of ten elementary symbols, from zero to nine. (44)

Arabic numerals were first transmitted and used in the West during the latter half of the twelfth century through the translation of the first part of al-Khawarizmi’s The Book of Addition and Subtraction in Indian Arithmetic, which survives as a translation only. By this time, many other important works in Arabic were well ahead of the West, including the work of al-Karaji (c.1000), ˜Umar al-Khayyam (d. 1130), as-Samaw’al (d. c. 1175), and Ibn al-Haytham (d. c. 1040).

Muslims also developed Greek geometry and then used it in surveying, in designing wheels of all kinds, including waterwheels and other systems for drawing water, in improving farming equipment, and, inevitably, in devising engines and devices of war, such as catapults and crossbows.(45) In the ninth century, Thabit ibn Qurra wrote on cubatures and quadratures, and used the method of exhaustions in a manner that anticipated the development of integral calculus; advanced the study of parabolas; and used integral sums to find the area of a parabola’s segment. He also translated Appollonius’ Conics, several of Archimedes’ treatises, and Nicomachus’ Introduction to Arithmetic, in addition to calculating the volume of the parabolic and giving a geometrical solution to some third degree figures.(46)

In geometry, Umar al-Khayyam and al-Tusi re-examined the fifth postulate of Euclid concerning the parallel line theorem, which concerns the very foundation of Euclidean geometry.47 Though they did not claim to challenge Euclid’s postulates, however, their work eventually led to G. Saccheri’s first attempt to formulate a non-Euclidean geometry (1733).

While the Greeks had calculated a table of chords, trigonometry was invented by the Arabs. (48) Muslim scientists were the first to formulate explicit trigonometric functions. The first scientist to use tangents (zill) was the astronomer Habash al-Hasib, who also knew of the sine, cosine, and cotangent functions. More influential was Abu al-Wafa al-Buzanji, the first person to demonstrate the sine theorem for a general spherical triangle and to invent the secant (qutr al-zill). The latter discovery is usually attributed to Copernicus. Al-Biruni wrote the first independent work on spherical trigonometry, calculated the approximate value of a diagonal of one degree, and was the first to demonstrate that for a plane triangle ( a/sinA = b/sinB = c/sinC ).(49)

Muslim mathematicians also invented algebra. Al-Khawarizmi (780-850), the greatest Muslim mathematician and the first to establish algebra, is known for being instrumental in converting Babylonian and Hindu numerals into a simple and workable system that almost everyone could use.(50) He is also best known for originating the mathematical terms and concepts of algebra and the algorithm (which is derived from his name al-Khawarizmi). He composed many astronomical tables, worked on arithmetic and algebra, and is recognized as the founder of algebra, for he initiated the subject in a systematic form and developed it to the extent of giving analytical solutions of linear and quadratic equations.

His book The Book of Summary concerning the Process of Calculating Compulsion and Equation was used until the sixteenth century as the principle textbook of European universities. And it is from its title that the term algebra (al-Jabr: restoration and amplification of something incomplete; muqabala: the balance of the two sides of an equation) was derived. The Toledan translation of his book, Algorismi de numero indorum, had a profound impact upon the West and gave English such words as algorithm and cipher (Arabic for zero) and Spanish the word guarismo.

One of the many other mathematicians, the Persian Ghiyath al-Din Jamshid al-Kashani, devised a theory of numbers and techniques of computation that remained unmatched until recently. He also rediscovered the decimal fraction, discovered initially by al-Uqlidisi and then forgotten for centuries, made a remarkably accurate calculation of , is considered the inventor of the first calculating machine,(51) and is the first person to solve the Newton binomial theorem.

Originality in astronomy

George Saliba, a prominent historian of Islamic science, has greatly advanced our understanding of the importance of Islamic astronomy. He explains that medieval Islamic astronomers were not mere translators but also may have played a key role in the Copernican revolution, which ultimately influenced the Renaissance. The contribution of Islamic science was fundamental to the birth and subsequent development of astronomy in the West, for before this contribution the West had no advanced astronomy. The knowledge developed by Muslim astronomers produced changes in the West as regards the development of trigonometry, instruments, and the local star catalogues, and also affected the growth and development of astronomical theory proper.(52)

Astronomy was a practical science for the Muslims, because they used the stars as guides during their travel. Thus, astronomy became one of their greatest achievements. Its practical importance was also emphasized by the need to determine the prayer direction (qibla) and time regardless of one’s location.

Islamic astronomers surpassed the Greek mathematical methods, and developed trigonometry, which eventually provided the essential tools necessary for the astronomy that developed during the Renaissance. Medieval Muslim astronomers felt themselves challenged to find a simpler trigonometric method than that postulated by such earlier astronomers as Ptolemy. The study of astronomy was influenced by ancient sources, and Muslims were acquainted with Indian and Persian sources before Greek ones. The Persian Sassanids’ astronomical treatises were translated into Arabic during the eighth century. Ptolemy’s work was introduced in the ninth century. Around that time, such scholars as Thabit ibn Qurra and Hunayn ibn Ishaq translated Ptolemy’s major work Megalé syntax mathematiké (Almagest in Arabic). By the end of the ninth century, the Arabs had thoroughly studied and were acquainted with the work of Antiquity.

Before the spread of Islam, there was only one observatory in Alexandria; Muslims built observatories all over the Islamic world. The first one, al-Shammasiyah, was built in Baghdad built by al-Ma’mun in 828. Al-Battani built one at Raqqa (Iraq), Abdul Rahman al-Sufi built one at Shiraz (Persia), and in 1023 the Persian prince Ala al-Daula built one for Ibn Sina at Hamadan. Scientists at the famous al-Maragha observatory in western Iran greatly influenced Copernican astronomy, for their work led to the development of a planetary system that was mathematically equivalent to that of Copernicus. Such closeness caused Noel Swerdlow to ask, not whether, but when, where, and in what form Copernicus learned of those scientists.(53)

Advances in planetary theories were primarily the result of criticizing Ptolemy’s work, which had dominated the field since the time of al-Battani. While refining and improving the work’s details, rising dissatisfaction with many of its aspects led such scholars as Nasir al-Din al-Tusi, Qutb al-Din al-Shirazi, and Ibn al-Shatir to criticize the Polemic (geocentric) system in the twelfth and thirteenth centuries. This criticism was, to some extent, very important in the later attacks made against him during the Renaissance. The work of astronomers like Ibn al-Shatir allows modern scholars like Saliba to conclude that at some level the Renaissance “ which was at least partly inspired by the Copernican revolution “ was not a purely European creation.(54) According to him, the role of Arabic astronomy was not to preserve Greek astronomy, but to correct its flaws and finally to seek alternatives to it.(55)

Thousands of Arabic manuscripts in major libraries remain unknown to scholars. However, eminent scholars like George Saliba and David King have advanced our understanding of Islamic astronomy’s originality and influence. Unlike the traditional view that Muslim astronomers accepted the Greek work as unalloyed truth, they in fact rejected much of it and forged a new astronomy that, later on, enabled Copernicus to lay the foundation of modern astronomy. Consequently, the original contributions made by Muslims astronomers challenge the idea that Muslim scientists only transmitted ancient Greek science and knowledge to medieval Europe without adding anything.

Originality in medicine

Muslims also excelled in and made original contributions to medicine. Islamic medicine was built on tradition, mainly the theoretical and practical knowledge developed in Greece and Rome. For Muslim scholars, Galen and Hippocrates were the pre-eminent authorities, followed by the Hellenic scholars in Alexandria. Muslim and non-Muslim scholars translated the voluminous writings from Greek (e.g., Hippocrates, Dioscorides, and Galen) into Arabic, thus providing virtually all of Islam’s early medical students with their basic reference texts. Then, basing themselves upon these texts, they produced new medical knowledge. In order to make ancient medical works more accessible, understandable, and teachable, Muslim scholars ordered and systematized the vast and sometimes inconsistent Greco-Roman medical knowledge by writing encyclopedias and summaries.

The influence of Islamic medicine in the West was critical, due to the mass of information it conveyed to the West, because it helped establish medicine as a science, and because translated Arabic medical manuscripts gave a decisive direction to the teaching of medicine in the West.(56) Islamic medical knowledge built upon the achievements of classical Greece and Rome as well as that learned from Syriac, Persian, and Indian sources. After the relatively quick assimilation of this knowledge, Islamic medical writings became more systematic and synthetic, with an evident urge to produce the most comprehensive and complete medical reference work yet written.(57) A primary concern of Islamic medical scholars was the organisation of the vast body of knowledge into a logical and accessible format.(58) They also expanded theoretical discourses on causes and symptoms, and frequently introduced examples and procedures of an applied character. It was in this historical background that Islamic medicine developed and advanced, and at its zenith produced such towering physicians like Ibn Sina and al-Razi.

Al-Razi (Rhazes: 865-925) is the keenest original thinker and greatest clinician not only of Islam but of the Middle Ages,(59) and was the Islamic world’s greatest original clinical and observational physician. Along with Ibn Sina, they are considered to be among the greatest physicians ever known. In selecting a new site for the great hospital in Baghdad, al-Razi hung up shreds of meat and then chose the spot where they showed the least sign of putrefaction.

Al-Razi applied chemistry and physics to medicine, and wrote a medical encyclopedia and a treatise on smallpox and measles that was the earliest of its kind and considered a masterpiece of Arabic medical literature. He was a pioneer in pediatrics, obstetrics, and ophthalmology. In fact, his The Diseases of Children has led some historians to regard him as the father of pediatrics. He is also considered the inventor of the seton in surgery, and the first to relate hay fever to a rose’s scent,(60) isolate and use alcohol (al-kuhul) as an antiseptic, use mercury as a purgative (known in the Middle Ages as Album Rhasis), explain how to remove a cataract, and discuss the papillary reaction or widening and narrowing of an eye’s pupil. Furthermore, he mastered the way of treating by psychological shock and of using psychosomatic medicine and psychology. In its English translation, al-Razi’s Spiritual Physic devotes 20 chapters to various ailments that upset the soul and the body.

Al-Razi wrote many books on medicine, the major ones being Al-Hawi fi al-Tibb, (The Comprehensive Book), an encyclopedic composition of Greek, Persian, and early Arabic medical knowledge in their entirety, whose modern version is incomplete at 23 volumes.(61) The Sicilian Jewish physician Faraj (Farragut) ibn Salim was the first to translate Al-Hawi into Latin in 1279. Under the title Continens, it was repeatedly printed from 1486 onwards; a fifth edition appeared in Venice in 1542. Prior to the nineteenth century, Al-Hawi can be considered one of the most extensive medical texts ever written by a doctor.

His 10-volume Kitab al-Mansuri (Liber medicinalis ad Almansori), was translated in 1480 by Milan, and also into French and German. Gerard of Cremona translated the ninth volume, under the title Nonus al-Manuri, which remained popular in Europe until the sixteenth century. Here, he developed the science of anatomy by discussing such features as veins, arteries, dispositions of the heart, and so on.

His famous book on smallpox and the measles, Kitab fi al-Jadari wa al-Hasbah (Liber de Pestilentia), was very influential in Europe. It was first translated into Latin in 1565, and then into many other European languages. In fact, 40 editions were printed between 1498 and 1866. In 1848, William A. Greenhill translated it into English. Through this treatise, he became the first to draw clear comparison between smallpox and chickenpox. This treatise demonstrates quite well his concern for therapy, and its thoroughness stands in sharp contrast to the silence regarding the topic in the Hellenistic and Byzantine literature preserved today.(62)

Another great figure, Ibn Sina (Avicenna: 1126-98), was the most renowned physician, philosopher, encyclopedist, mathematician, and astronomer of his time. According to George Sarton, Ibn Sina’s thought represents the climax of medieval philosophy.(63)

One of his major contributions to medicine was his famous Al-Qanun fi al-Tibb (The Canon of Medicine), an immense encyclopedia of medicine that contains some of the most illuminating thoughts on the distinction of mediastinitis from pleurisy; contagious nature of phthisis; distribution of diseases by water and soil; careful description of skin troubles; of sexual diseases, and perversions; of nervous ailments (including love sickness); many psychological and pathological facts clearly analysed.(64) In it, Ibn Sina deals with the general principles of medicine, simple and compound drugs containing 760 types of drugs, disorders of each internal and external organ of the body, and diseases effecting all of the body, especially pathology and pharmacopoeia.

The Canon influenced Europe’s medical schools for the next 600 years and was probably the most used of all medieval medical references.(65) Gerard of Cremona translated it in the twelfth century. During the last 30 years of the fifteenth century, 15 Latin editions and one Hebrew edition were published. During the sixteenth century, it was reissued more than 20 times. From the twelfth to the seventeenth century, it was the West’s chief medical book and fulfilled that function longer than any other medical work.

Ibn Sina was the first to describe meningitis and differentiate it from meningismus of other acute diseases and to suggest treatment for lachrymal fistula, the first to describe the manner of spread of epidemics and the contagious nature of tuberculosis. He described many details of the eye, such as conjunctive sclera, the cornea, choroids, the iris, the retina, the layer lens, the aqueous humour, the optic nerve, and the optic chiasm.

Other important medical figures were Ibn Zuhr (Avenzoar, d.1161) for his work on diet, Ibn Rushd (Averroes, 1121-98) for his work on general principles, and the Syrian Ibn al-Nafis (d.1288) for his discovery of the minor circulation of the blood.

Conclusion

The contribution of Muslims to science dispels the common beliefs that they only preserved and transmitted Greek knowledge to the West. Recent studies by competent historians has led to a qualitative shift in our understanding of their contributions. Such historians adduce that Muslim scientists both influenced almost every branch of science and were instrumental in influencing the Renaissance.

Today, however, the Muslim world produces a disproportionately small amount of scientific output, and much of it is of relatively low quality. In numerical terms, 41 predominantly Muslim countries, having about 20% of the world’s population, generate less than 5% of its science. Given Muslims past contributions to science, this situation raises several questions: Is there a dichotomy between Islam and modern science? If not, how does one explain the huge gap in scientific output between the Muslim world and the West or East Asia? And what must change so that science can flourish in Muslim countries?

The past achievements of Muslim scientists clearly show that Islam is not the key problem facing scientific achievement in the Muslim world of today. The theory that implies a dichotomy between Islam and science is part of a larger conflict in post-Enlightenment historiography that opposes science and religion in general in post-medieval civilizations. Rather, the problem is a result of cumulative “ as opposed to one dominant “ factors.

Ancient people, considering it very important to determine Earth’shape, derived two important clues from the night skies. According to Aristotle (384-322 bce), these were lunar eclipses and the North Star. Lunar eclipses occur when the sun, Earth, and the moon line up in such a way that Earth temporarily blocks the sun’s light from reaching the moon while its circular shadow gradually crosses the moon’s face. The North Star appears lower in the sky the further south we go: at the Equator it lies directly on the horizon, at a latitude of 45 it is 45 above the horizon; and at the North Pole it is directly overhead. However, it is not visible south of the Equator.(1) As both of these indicate a spherical Earth, the scholars of that time discarded the idea of a flat Earth.

The more challenging question was how to determine Earth’s size. Eratosthenes of Alexandria (third century bce) had a simple yet brilliant idea: insert a gnomon (a vertical stick) into a level piece of ground. This enabled him to determine noon’s exact time (when the shadow was the shortest). It was also used as a compass, for in the Northern Hemisphere the gnomon’s shadow points north.

But can such a simple device determine Earth’s size? Aswan, located about 500 miles south of Alexandria, sits on the Tropic of Cancer. So, at noon of June 21 (the summer solstice), a gnomon inserted there has no shadow. By doing just that in Alexandria, Eratosthenes found that the angle was 1/50 of a circle’s circumference (i.e., 2p/50). In other words, the angle at Earth’s center corresponding to the arc between Aswan and Alexandria on Earth’s surface is 1/50 of a circle’s circumference. Since the distance between Alexandria and Aswan is 500 miles, Earth’s circumference should be 25,000 miles, which is its actual circumference.(2) Thus, Earth’s size and shape was pretty well established over 2,000 years ago.

This knowledge was lost to Europe when the ancient civilizations crumbled. But Islamic civilization and culture, which was rising at roughly the same time as the West was declining, produced scholars and scientists who translated and refined quite a bit of this ancient knowledge. For example, in 1424 al-Kashi used Archimedes’ method of computing to determine its values to 16 decimal places. Ulug Beg compiled the greatest star catalog known at that time. During al-Ma’mun reign (813-833), al-Khwarizmi measured one degree of latitude on Earth’s surface and obtained the result of 57 miles. This means that Earth’s circumference is 360×57 = 20,520 miles.(3) Thus, in the ninth century, Muslim scientists knew that Earth was spherical and had a good idea of its size. Most Europeans at that time, believed that Earth was flat and the universe impenetrable.

The Qur’an describes Earth’s geographical shape and change in that shape: Do they not see how We gradually shrink the land from its outlying borders? Is it then they who will be victors? (21:44).(4) The reference to shrinking could relate to the now-known fact that Earth is compressed at the poles.

At a time when people generally believed that Earth was flat and stationary, the Qur’an explicitly and implicitly revealed that it is round. More unexpectedly still, it also says that its precise shape is more like an ostrich egg than a sphere: After than He shaped Earth like an egg, whence He caused to spring forth the water thereof, and the pasture thereof (79: 30-32).

The verb daha’ means “to shape like an egg,” and its derived noun da’hia is still used to mean “an egg.” As this may have appeared incorrect to pre-modern scientists, some interpreters misunderstood the word’s meaning as “stretched out,” perhaps fearing that its literal meaning would only confuse people. Modern scientific instruments recently established that Earth is shaped more like an egg than a perfect sphere, and that there is a slight flattening around the poles and a slight curving around the Equator.

The West receives “lost” knowledge

An enduring Western myth is that Columbus had to overcome a pervasive belief that he would sail off the edge of a flat Earth by sailing west to Asia. This myth stems in part from compressing the past and conflating the early Middle Ages, when Europe’s belief in a flat Earth was widespread, with the late Middle Ages, when Europe’s knowledge had caught up with and partially surpassed that of ancient Greece and medieval Islam.

During the Renaissance, Europe came into contact with “lost” knowledge by translating Greek and Arabic works. One important book was Ptolemy’s Geography, which accepts Earth’s spherical shape. Geography once more became available in the original Greek, which was not widely known in the thirteenth century. This book was translated into Latin in the late fifteenth century and became widely known. Columbus owned a copy printed in 1479.

By the time of Columbus, the idea of a spherical Earth was widely accepted in theory. Columbus believed this and wanted to sail west to the eastern shores of Asia. Earth’s size was the real issue. Ptolemy’s estimate was as much as 20% too low. Also, he vastly overestimated Asia’s size. The resulting map depicted an Earth with oceans between Europe’s western tip and Asia’s eastern tip, which was well within range of the provisions that ships of that time could carry. Columbus’ estimate of the distance to Asia was wrong, as was his assumption that there was no land between Europe and Asia. Fortunately for him, these two “wrongs” made a “right,” with all of its attendant fame and glory.

The Shape of the Universe

So far, we have given external information (i.e., lunar eclipses and the North Star) about Earth’s spherical shape based upon its position in the universe. If we use this method to determine the universe’s shape, we must observe it in an external manner. As this is not possible, let’s reconsider the question of Earth’s shape with a slight change: Can we determine Earth’s shape by using measurements and observations done only on its surface, and thereby acquire intrinsic information that can inform us of the universe’s shape?

Karl Gauss (1777-1855) answered this question positively by inventing “curvature,” which measures a given surface’s “bumpiness” at a specific point. A flat piece of paper has no bumps and so its curvature is zero. But if we look at a sphere at each point, we see some bumpiness. Gauss called such bumpiness “positive curvature.” Another kind of bumpiness is “saddle-shaped.” We can think of positive curvature at a point as follows: If we put a piece of flat paper on a surface at that point, the surface lies totally on one side of the paper. But in negatively curved space, this cannot happen.

To describe this concept formally (minus some technicalities), assume constant curvatures on the shapes in question. In other words, the shape is totally symmetric and every point has the same amount of bumpiness. There are several ways to describe curvature. Gauss’s formulation for curvature is brilliant. But before that, let’s look at his intrinsic proof for a spherical Earth. Imagine an orchard so large that any deviation from flatness is perceptible. First plant trees on the Equator every 100 kms (the approximate distance between two meridians on the Equator). Then plant another tree 100 kms (the approximate distance between two parallels) north of each tree, and do this several times. If Earth is flat, the distance between them would be same. But since the distance between the two consecutive trees (on the same parallel) decreases, Earth is spherical.

Having seen that an intuitively positive curvature implies a spherical shape, we want to follow this method to get an idea about the universe’s shape. Georg Riemann (1826-66), trying to do just that, invented “curved space” and explained how to compute its curvature. We could launch six probes at equally spaced points along the Equator, and have each of them continually monitor the distance to the two adjacent probes. If space is flat, the distances at any point in its journey would equal the distance from the probe to Earth’s center (an equilateral triangle). For negative curvature, the distance between probes would grow faster than the distance the probe had traveled from Earth; in positively curved space, the distance between probes would grow slower than the distance covered by the probes since leaving Earth.

There are two common misconceptions about the curvature of space. The first one is that curvature is a rather vague or qualitative concept. In reality, it is quite precise and assigns to each point in space and each direction at that point an exact number determined by the shape of the space near the specific location. The second one is that to describe curved space, one must think of it as “curving” into a fourth dimension. This can be useful in visualizing curved space for people familiar with four-dimensional Euclidean space (four-dimensional coordinate space). Unfortunately, science popularizers and science fiction writers often lace this concept with mystical overtones. This is more likely to confuse average people. In other words, measurements made in ordinary three-dimensional space may disagree with the results embodied in Euclidean geometry, for curvature measures the degree and kind of deviation from the Euclidean model.

Riemann also proposed a radically different (non-Euclidian) model for the universe: “spherical space.” This would be the case if space had a constant positive curvature. Based on this, he said that the universe should be a hypersphere (a three-dimensional sphere). The usual sphere is two-dimensional and lives in three-dimensional Euclidean space. In general, n-dimensional sphere is described as in the (n+1)-dimensional Euclidean space, and the set of points whose distance from origin (the point 0) is 1.

The more intuitive way to describe hypersphere comes from the usual sphere. Starting from a point in the sphere called the South Pole, and as we go in a direction in the sphere, we see concentric circles becoming larger until we reach the Equator, after which they become smaller and we finally reach North Pole. The situation is similar in hypersphere. Start from a point in the sphere called the South Pole, and as we go in a direction in the sphere, the concentric “spheres” become larger until we reach the Equator, after which they become smaller until we reach the North Pole. We can generalize this concept for any sphere of any dimension.

Earlier philosophers speculated that the universe was infinite in extent; others (e.g., Plato, Aristotle, Newton, and Leibniz) rejected this as implausible. But the alternative seemed equally dubious: If it did not go on forever, then “like the flat Earth” it had to end somewhere. And, what was beyond that? This model solved the Euclidean paradox of the universe’s “edge,” for if the universe is positively curved, it can be finite in extent and still not have any “edge.” In Riemann’s model, every part of the universe looks just like every other part, as far as shapes and measurements go.

Qur’an 51:47-48 mentions the universe’s spreading out or expansion in space: And the firmament: We constructed it with power and skill, and We are spreading it. This verse reveals that the distance between celestial bodies is increasing, which means that the universe is expanding.

Hubbel’s law

The most surprising discovery of the twentieth century was made by Edwin Hubble in 1929: The universe is not static, but is in a state of rapid expansion. Based upon his observations, he stated Hubble’s Law: Other galaxies are receding from us, the rate at which they recede depends upon their distance, and there is a constant ratio (the Hubble constant) between their velocity and their distance from us.

This law’s most dramatic consequence is what it tells about how we got to where we are now. If distances between galaxies increase as we look toward the future, they must decrease as we go back in time. Each ring of galaxies must have been closer to us in the past; the further away (or back in time) we go, the closer they would have been, and the faster they appear to be moving toward us.

Hubbel’s evidence was limited to a few relatively nearby galaxies. Over the years, however, thousands of observations extended and refined the measurements, and confirmed the general correctness of the velocity-distance relation. Current best estimates are that those galaxies are a billion light-years away (a light-year is roughly 6 trillion miles). Assuming that light always travels at the same speed, those galaxies must have been 1/20 of a light-year closer to us each year in the past. To have ended up a billion light years away, they must have started at exactly the same point as we did “the Big Bang” some 20 billion years ago.

Let’s start by using concentric rings of galaxies at intervals of a billion light-years. Then there are 20 rings, because five rings from us represents galaxies 5 billion light-years distant from us. To see them, we need to see their light that has been traveling for 5 billion years. Thus, we now see their position 5 billion years ago. As there was nothing 20 billion years ago, the outmost ring must the twentieth ring. This might sound paradoxical, as the circles of galaxies seem to grow larger as they move further away from us. However, the paradox is only apparent. Assuming Earth is in the South Pole and that the rings are a sphere’s latitudes, the rings become larger by the Equator and then become smaller until, in the twentieth ring, we reach the North Pole. This time, the rings are spheres and thus fit in the hypersphere. So Hubble’s Law supports our model of hypersphere for the universe.

But how can an expanding universe fit into our picture? In the sphere, the whole surface is expanding, just like inflating a balloon. So the distance from us (at Earth) to the Big Bang is increasing in all directions. In other words, any two points in the universe recede from each other, just as any two points on the balloon recede from each other during inflation.

The issue of time

So far, we have considered the universe’s shape at a fixed time. But, in physics, it is useful to consider space and time together. After Einstein’s brilliant publications about special relativity, Hermann Minkowski (1864-1909) proposed a very useful four-dimensional space-time model as the fabric of the physical universe. In a global picture, each fixed time represents a thin slice of space-time. Like an onion, each layer (assuming there are infinite very thin layers) corresponds to the universe at different fixed times. Given that each fixed time is a hypersphere, the layers are hyperspheres. According to Hubble’s Law, the hypersphere becomes larger as time passes. Just like an onion, the inner layers are smaller and the outer layers are larger.

In an ordinary onion, the layers are usually spheres; in the universe, the layers are hyperspheres. Assuming that the outer-most slice represents the universe at this time, the space-time “so far” is a four-dimensional onion, with layers of the universe at different times. The center of this “onion” corresponds to the Big Bang. We receive the picture of space-time until “this time.” Now, let mathematics predict the future of the space-time, just as Newton’s laws allowed a detailed description of the solar system’s future course. As time evolves, the universe expands, distances between galaxies grow, and gravity weakens. Thus, the space-time curvature diminishes and successive hyperspheres grow at a slower rate.

Two possibilities emerge: The hyperspheres continue to grow indefinitely, although at an ever-decreasing rate, or reach a maximum size and start to contract, in exactly the same fashion as the parallels of latitude on Earth: starting at the North Pole, growing until they reach their maximum size at the Equator, and then begin contracting toward the South Pole. If the universe contracts, distances between galaxies would decrease, gravity and curvature would increase, and the successive hyperspheres would shrink ever faster, eventually contracting into a single point: the “Big Crunch.”

We could then draw a map of the universe as a succession of hyperspheres growing in size for during the first half of its life and contracting during the second half. All space-time would then form a kind of super-hypersphere a four-dimensional object known as a “four-dimensional sphere.”

Conclusion

At a fixed time, the universe should be a hypersphere. When the time dimension is added, space-time should be super-hypersphere, with a “Big Bang” like the South Pole, each fixed time of the universe corresponding to the parallels, and finally a “Big Crunch” corresponding to the North Pole in our space-time model.

Almost everybody has heard that time is the fourth dimension. Even though this concept is easy to imagine, people find it hard to understand because of its mystification by science popularizers. We live in three-dimensional space. This means that I can parameterize the universe such that I can describe any point in it by using just three letters (a, b, c).

Footnotes

1. All of these statements are only approximately true. They would be exactly true if the North Star was precisely overhead at the North Pole, instead of being off center by about 1.
2. The real estimate might not be 25,000 miles, as we do not know the exact correspondence between ancient and current measurements. However, this was a very good estimate for that time.
3. Despite the potential errors mentioned in footnote 2, this also was a good estimate for that time.

It is important to understand the advantages and disadvantages of perceiving visual information. Throughout history, written and visual information (shapes and pictures) have been used together to perceive, think and, communicate. The discovery of the camera in 1895 enabled pictures of objects to be stored permanently. Photographic techniques also accelerated the development of science and industry.

In 1895, Roentgen discovered x-rays and developed a method to show a person’s bones and internal organs. This gave visual information-based perception more importance. In the past, we tried to sense and understand the surrounding world by using the naked eye within a narrow band of energy originating from the sun. Later on, we realized that we could see only a fraction of what was there.

Virtual reality

Virtual reality environments make perceiving and learning easier and more effective. Events that are expensive and require a long time to perceive and learn can be perceived and learned with less effort and less cost. For example, a virtual reality environment enables a person to tour the ocean’s bottom and deep space within several minutes. In addition, it reveals formerly unseen micro- and macro-objects visible to the naked eye, just as if they were being seen in a dream or were real.

The most powerful visual information techniques are in the advertising, marketing, news, and entertainment sectors. The virtual reality environment is just one cutting-edge development. To gain self-control and learn effectively, an individual can be placed in such an environment, which fully replicates the real world. Such environments are used, for example, to train pilots and doctors. Another suitable use would be to train Muslims for Hajj and Umrah. Such an experience would familiarize them with Makka and Madina, thereby lessening the potential for unexpected problems and better prepare them intellectually and spiritually for these holy voyages.

Visual information and education

The techniques of making objects visible started with discovery of the microscope and the telescope. When combined with multimedia technology, they have an important place in modern education. The correct and effective use of visual information and written information-based perception is improving the quality of education. Similarly, popular Web pages have been transformed into marketing environments that convey their messages through the combined use of scripts, images, sounds, and animation.

Surrounded by these visual tools and techniques, the media has a greater influence upon society than ever before, for it controls the visual information. Educators should teach their students how to analyze and criticize visual information, for producing fake computer-produced images in a visual information-based environment is almost as easy as producing fake written information with a copy machines. They must learn not to believe everything that they see, just as their parents learned not to believe everything that they read in the newspapers.

Conclusion

During the last several centuries, humanity has been led to believe that seeing is believing and don’t believe in what you can’t see. However, advanced visual processing techniques prove that not everything that we see is correct. In fact, such techniques might actually misled individuals, for they can produce images or virtual reality environments very close to the real one.

The various eras

The prehistoric era is considered an unknowable time inhabited by primitive and brutal humans. This era ends with the beginning of Antiquity, which saw the rise of ancient civilizations in Egypt, Mesopotamia, India, and China. However, the West downplays them, as if they somehow damage its ego and pride.

Then comes late Antiquity, the era of classical Greece and Rome, a sort of golden age during which the West was enlightened by such philosophers as Socrates, Aristotle, and Plato, as well as by beautiful artistic and literary creations. However, these people worshipped deities, did not obey any moral codes, and also had a great thirst for stories about bandits. The Greeks of this time, however, failed to comprehend the reality of the miraculous incidents in nature and so worshipped the sun, wind, fire, and forests. Rome, a civilization based upon law, categorized people into social classes varying from superior to slave. In 380, it adopted Christianity as its official religion. Antiquity ended after the empire’s division into two and the collapse of its western portion not too long after the division.

The next approximately 1,000 years are known as the medieval era. It started off by destroying Antiquity’s intellectual and artistic works and forbidding independent thought. The Christian church, after closing down Athens Plato Academy in 529, turned toward monasticism and rejected Greek philosophy. Monasteries soon gained a monopoly over education, thought, and meditation. This is why the times became dark, for the clergy monopolized science, culture, art, literature, and thought. Religion, which provides people with peace, happiness, and security, was distorted and, assuming a personalized form, became a means of torment, oppression, and harassment through the above-mentioned bans, church taxes, and the Inquisition.

During this era, which considered such moral values such as equality, justice, love, and respect outdated, people were classified as clergy, which produced nothing but confiscated and controlled everything; nobles, who owned and exploited the land and treated the peasants as serfs; peasants who worked but could only silence their hunger; and slaves. The medieval era ended with the advent of the Renaissance (rebirth or revival), which began in northern Italy in the late fourteenth century and spread north thereafter. Antiquity’s thought, art, and culture were revived, and people tried to free themselves from feudalism and church authority.

What really happened during the dark ages?

The Dark Ages are often ignored. However, this was the time when Europe rediscovered Antiquity’s accomplishments and thought due to its contacts with Muslim Spain and Byzantium. Given this reality, why does the typical timeline skip over this period, especially since it was far from dark outside of Europe? One case stands out: the Arabian peninsula, where a new religious movement (Islam) and the beginnings of its civilization had appeared by 610. In stark contrast with Europe, it proclaimed that people were obligated to seek knowledge, fight ignorance, and improve their condition in life.

Islam’s Prophet, Muhammad, accepted Judaism and Christianity as true and set about re-establishing belief in God’s Oneness. He preached the freedom of conscience and religion by declaring there is no force in religion and that people should embrace Islam only if they sincerely believed in its truth. The Qur’an rejected all humanized angels and rejected Original Sin by stating that people would be rewarded or punished only for their own deeds in the afterlife.

The security of life, goods, and honor were accepted as basic human rights, and thus guaranteed protection. All people, without exception, had specific property rights. Each person’s rights were guaranteed by being considered halal (lawful) or haram (unlawful), with various gradations in between. Social solidarity was ensured by zakat (obligatory charity) and sadaqah (voluntary charity). This also prevented the formation of social classes and any possible class hostility. Addressing humanity as O people to show their equality, the Qur’an rejected medieval Europe’s social stratification by proclaiming that superiority depended upon belief, God-consciousness, good conduct, and helping others.

In the pre-Islamic period, women were viewed as property and daughters were considered a source of shame for their fathers. Islam made them revered spouses and beloved daughters, superior to men in being mothers, and equal in obtaining property and justice. Islam sought to abolish slavery, a universal norm at the time, gradually by introducing various sanctions. First of all, it recognized slaves as full human beings who had to be treated according to the dictum Let them eat what you eat, and let them wear what you wear. Moreover, God ordered the freeing of slaves to atone for some sins.

Islam emphasized the wrongness of medieval Europe’s social stratification by stating that everybody was equal before law. The principle of freedom from obligation, which states that everybody is essentially innocent until proven guilty, was also established. All of these practices, which have existed from the first day of Islam, have not been cancelled just because many Muslims have not observed them.

Conclusion

While Europe remained in the dark on all of the above issues, the sun of Islam was beginning to illuminate many other areas of the world. Thus, humanity’s progress toward real civilization was led by Islam during an era that was supposedly dark. As Islamic history shows, that classification betrays some obvious personal or civilizational bias.

Europe’s Dark Age was a time of great intellectual ferment in the Islamic world. Many philosophical, mathematical, medical, astronomical, and medical works produced by classical Greece and Rome, as well as India and other civilizations, was translated into Arabic by Muslims, Jews, and Christians. Among them were the works of Aristotle, Plato, Socrates, Hippocrates, Euclid, Galinos, Ptolemy, and Archimedes. Such translations had a major impact upon Europe when they finally reached its shores, for they were instrumental in starting the Renaissance.

The present division of history into certain eras is based upon a Western view of history and what is important. The church rejected Antiquity’s accomplishments and caused it to be forgotten in Europe for many centuries. However, religion cannot be condemned for this, for the people who did such things deviated from its teachings. While Europe was lost in darkness, Muslims were busy creating an Islamic civilization that first enlightened their own lands and then spread outwards Spain (Andalusia). Muslim Spain eventually became a bridge between the Islamic world and Christian Europe.

Greek civilization established the beautiful, Romans established the law, and the Semites contributed religion. The Chinese actualized the useful, India gave humanity its imagination and mysticism, and Europe gave science. Islamic civilization assumed its rightful place among the world’s civilizations by exhibiting an intrinsic and original style in areas such as thought, science, art, culture, and literature. Such a magnificent civilization, if it is to be divided into eras, should be divided according to its own history, and not by the West’s criteria. Just as the West arose again, thanks to Islamic civilization, so will the Islamic world rise again, God willing.

The widely accepted argument today is that the elements used as building blocks of life were first backed in the nuclear furnaces of stars under extra ordinary heat and pressure, undergoing a series of transformations and took their forms as we realize them on our earth. Among all the elements on our planet earth, the unique properties given to carbon and hydrogen elements has made the existence of carbon-based life forms possible.

Carbon combined with different elements in many different quantities and geometric arrangements, results in a vast assortment of materials with vastly different properties.

The molecules that are found in live organisms are created from different quantities, geometric arrangements and assortments of carbon, hydrogen, oxygen, phosphorus, nitrogen and sulfur. The base properties of carbon are playing an important role in creating these compounds.

Each carbon atom makes four bonds. Carbon may make bonds with other carbon atoms forming chains, branching chains or rings of linked carbon atoms. These properties given to carbon are important factors in the miracle called life.

When a carbon atom makes bounds with four hydrogen atoms methane gas is obtained (CH4). If we exchange the hydrogen atoms with oxygen atoms in methane we obtain carbon dioxide (CO2). If we exchange the hydrogen atoms with sulfur atoms in methane we obtain carbon disulfur (CS2), which is a combustible and poisonous liquid.

If we exchange the hydrogen atoms with chlorine atoms in methane we obtain carbon tetrachloride CCl4. If we exchange the hydrogen atoms with fluoride atoms we obtain fluorocarbon compounds. The Teflon used in our kitchenware is a fluorocarbon resin.

When two carbon atoms each having three hydrogen atoms attached come together, the ethane molecule is formed. As mentioned before chains, branching chains and rings of linked carbon atoms can be formed this way. Some carbon compound’s molecules consist of just a few atoms; others contain thousands or even millions. This is one of the main reasons of organic versatility that is behind the scene. Attaching other functional groups to the carbon atoms in the chain increases the versatility of compounds. Some examples of these functional groups that are built up with carbon, oxygen, hydrogen, phosphorus, nitrogen and sulfur coming to mind at first would be the hydroxyl functional group (OH), the carboxyl functional group (COOH), the methyl functional group (CH3), the amino functional group (NH2), the phosphate functional group (PO4), the carbonyl functional group (CO) and the sulfhydryl functional group (SH).

If we exchange one hydrogen atom in methane with a hydroxyl group we obtain methanol, which is an alcohol that damages the optic nerves. To turn methanol into ethanol, which is found in alcoholic beverages we need to add a methyl group to methanol. If we add one oxygen atom or a carboxyl group to ethyl alcohol we will obtain acetic acid (vinegar acid). Adding a nitrogen atom or an amino functional group to acetic acid we obtain amino acids, which are the building blocks of proteins. Looking to these examples we understand that a slight difference in the structure or order of the atoms within a compound can change the whole functionality of that compound. We realize that live systems are fragile and that very sensitive adjustments are made to create the right conditions for the existence of life and that delicate balances are kept to maintain the order of life, which we enjoy so much. Another important fact these examples can prove is that building everything from one thing or building one thing from everything is one of the aspects of creation. This aspect provides us valuable knowledge about creation.

We can explain this matter further with an analogy. To construct a building we need various materials like bricks, cement, wood and iron. Buildings with different architectures and functionalities are constructed with the same materials in different quantities and arrangements. Similarly, this amazing variety of life forms and the order of life on earth are brought to existence with only a few element types (carbon, hydrogen, oxygen, phosphorus, nitrogen and sulfur) which are brought together in different arrangements, representing infinite numbers of different shapes in space.

Life is protected from extinction with buildup and breakdown mechanisms, which change and convert these molecules from one to another.

The popular child game called LEGO is another example that can be used to explain how this infinite variety of life forms is created by a few types of elements. Children can build different objects according to their imagination by using the limited number of plastic pieces in different quantities and arrangements. Just like this, the most merciful has created the amazing nature and every living creature in it by using the limited number of elements in different arrangements and quantities.

Natural forms of pure carbon include graphite, one of the softest minerals known, and diamond, the hardest substance known. The only difference between the two is the structure of the bonds between carbon atoms. Diamond and Graphite, being the same chemical composition, but different crystal structures, are two polymorphs of pure carbon. Another example is aspirin, gasoline and vanillin oil. All three compounds are composed of carbon, oxygen and hydrogen atoms but their properties and usage are completely different. All these examples point to the attribute of creation stating that many things are made from one thing.

Another related topic is isomers. Hydrocarbon variations that differ only in the arrangement of atoms are called isomers. Isomers are very important in biology. The preference for some isomers of molecules that are used in the base metabolism of living beings and biological systems shows us that the existence of life is not without certain intentions and willpower. For example, only the D form isomer of glucose can be used by biological systems. Similarly when the C vitamins are produced synthetically in the lab environment, 50% of those are isomers. Because only one of the isomers is biologically active, our body can use only %50 of the C vitamins we buy from the drug stores.

To stay alive, the human body needs water, air and nutrition from the outside world. It is very important that the nutrition we take has enough elements like iron, zinc ant iodine in it. These elements take place in certain enzymes and molecules, which are important for some proteins and hormones to work properly. For example not having enough iodine in our nutrition can cause an enlargement of the thyroid, which shows up as an abnormal swelling in the neck called a goiter. This illness can be seen more often in mountainous regions where the soil has less iodine because the rainwater washes it away. This reflects on the vegetation and fruits grown in the region and causes the body to not produce enough thyroid hormones. When iodine in nutrition is less than a certain amount it can even slow down the brain development. Similarly iron deficiency causes anemia and zinc deficiency causes growth retardation.

In summary, the magical order and amazing complexity in nature is based on a few molecules, which are arranged in different shapes, orders and in different quantities.

It is one of the miracles of creation that all complex organizations and structures, which even have different specifications, are made from very basic building blocks. The science of complexity (chaos theory, fractal geometries, etc.) has begun to research how God, who is able to make one thing from everything and everything from one thing, has created these astonishing complex beings from very basic and plain molecules. This research to understand how this amazing order and complexity exists will open new doors for the 21’st century science.

A: Genuine knowledge (ilm) is a source of infinite light covered with truth, which leads enlightened people toward the righteous path. Modern science is built and developed upon existing information gained through experimentation and correcting previous errors. In general, science represents theories and hypotheses that we devise and pursue in order to acquire knowledge. From this point of view, knowledge and science are not the same and must not be considered as synonyms. For example, sometimes ilm is mistranslated as science, because the translators do not take into consideration the genuine meanings of the words. This mistake can be excused when it is made by the general population, who might not be aware of the difference; however, we expect scientists and professionals to use these terms correctly, according to their core meanings, so that their different meanings become obvious and clear.

Knowledge is born and developed between our hearts and minds. On the contrary, science is totally material, belongs to this world and all physical beings, and depends fully upon Earth’s natural rules. Science is born through theories, and its continued development always engenders doubt. Initially, science was built on rationalism and developed through positivism. It sprouts in the world of the five senses, and continues its life with reference to the theoretical mind. Most of the time, science rejects things that cannot be seen or heard. In fact, its eyes are blind to the concealed meaning of existence, and its ears cannot hear it. Modern science accepts only those objects and events that can be perceived by the five senses.

Scientific developments in the classical Islamic world have had a tremendous influence upon the achievements of modern science. Several Western scholars and writers, among them Maurice Bucaille, Jacques Cousteau, Alex Carrel, Thomas Carlyle, and Roger Garaudy agree with this fact, and state that the West totally owes all its achievements to the East. Andalusia, a Muslim state in Spain, was a perfect example of this process. In some cases, Western scientists considered the roots of the knowledge derived from the East to be abstract theories, and so they did not consider what they had given to humanity and upon what basics and pillars they had been built.

The West has mixed its materialistic ideas in the development of these ideas and sciences, and by restricting their analysis only to subjectivity, they alienated the roots from their origins. As a result, religion in the West was confined to the church and people could learn about their religion only when they came to the church to participate in religious ceremonies. Thus religion could not enter fully into the people’s lives. In fact, after Constantine, emperor of the Holy Roman Empire, proclaimed Christianity to be the empire’s official religion in 315, the government strictly controlled its all relations with life. This approach toward religion was a bad luck for Christianity. The first 3 centuries of Christianity was the best time for this religion, despite the severe pressure that it faced, for it was a time of blossoming and purity. After became the official religion, Christians no longer faced oppression. However, the religion fell under the control of the government and was corrupted. According to the state, religion belonged in the church, and while people occasionally would come to the church to practice their religion, they could not make it an intimate part of their life. As a result, Christianity was divorced from everyday life, society had to accept that there was life without religion, and that there was religion without life. Given this reality, scientific research and implications had nothing to do with Christianity, and that religion became a moral institution whose only responsibility and activities were the ceremonies connected to birth and death.

The West’s scientific roots lie in the classical Greek and Roman civilizations. This knowledge was incorporated into the Islamic civilization, whose scholars and scientists developed it, made original contributions to it, and passed it on to the West. Unfortunately, Western scientists developed modern science as an independent enterprise completely separate from religion. Thus, its scientific development was built of unbelief and differs dramatically from the understanding of science and knowledge in the East.

On the other hand, knowledge and science flourished for centuries in the Islamic world. Some of its luminaries are Jabir, Ibn al-Haytham, al-Khawarizmi, al-Zahrawi, Ibn Sina, and al-Farabi. Ancient Greek scholars claimed that the smallest particle of being is an atom. However, theologian Ibrahim al-Nazzam (d. 835/845) said that substance could be divided into pieces an infinite number of times, and spoke as a modern scientist who would say the same thing today. If we look at this from the theory of particles, it would be clear that al-Nazzam’s statements are true.

Muslim scholars never rejected or separated their inventions and discoveries from religion. Rather, knowledge and science reinforced their belief and understanding of religion. Even though they argued about various scientific matters, their attitude toward religion never differed from one another. For example, a Muslim physician-scholar like al-Razi had mystically spiritual intellect. Muslim scholars explored the universe in the name of The Creator, and every single discovery and invention brought a new passion, a new enthusiasm, and a spirit of new devotion. That is why they always traveled in the horizons of is there any more? and they lived in a state of continual passion of searching for the truth.

It is true that Muslim scholars understanding of knowledge developed their understanding of religion and created metaphysical tension in their lives. Several Qur’anic verses, such as: Behold! In the creation of the heavens and Earth, and the alternation of night and day, are Signs for men of understanding(3:190), always attracted Muslim scholars. Using such verses to inspire them, they devised their theories with a feeling of prayer toward God and built their knowledge upon a foundation of such an understanding and approach. Muslim scientists explored the heavens and Earth in the light of such verses, and learned and researched the relationship between the universe and Earth, such as the connection between a flower and the sun, the association of the smallest animals and living things to the sunlight, and so on. As a result of this approach, and by reciting the Qur’n while studying the universe (the Book of Existence), Muslim scholars strengthened their faith in and closeness to God.

However, due to today’s materialistic theories, Western scientists will never be free of the fear, anxiety, and unexpected surprises that might arise in their fields even though they reach the heavens and continue to solve the mysteries of the universe. On the contrary, Muslims believe that they can build castles even in the center of black holes, for: God’s Existence, Divine Beauty, and Power are behind everything. Perhaps black holes are no more than dark hallways toward brightness and light. As we enter the grave and come out of it toward Paradise, these undesired and unwanted black holes just might be bridges between the heavens and this world.

Western society, confined within the limits of discoveries and scientific inventions, cannot see the true beauty of the material world. But Muslim scholars and scientists, while learning and exploring life by means of Divine guidance and assistance, could read the wisdom and hidden purposes behind the things and events occurring in the material world and see God’s Divine Power behind everything in the universe. For example, consider the Islamic point of view toward the human face and appearance. Muslims never attributed such things to nature, which is unconscious and blind, but rather saw in that wonderfully beautiful human complexion the reflection of The Most Merciful and The Most Compassionate God. By seeking to increase their limited understanding, they made the limited unlimited and decorated simple mirrors with the most beautiful crafts and designs. From this point of view, Muslim scientists had the chance to see hidden wisdom and knowledge side by side, and could observe and witness clearly the things and events that were taking place in the material world.

The following Qur’anic verse describes such people: He grants wisdom to whomever He wills, and the one to whom wisdom is granted receives a benefit overflowing. However, none will grasp the Message but men of understanding (2:269). Such people with intellect can see the concealed wisdom. People who look to the universe without the glasses of wisdom and concealed truth see and observe things as unreasonable and useless.

Islam understands ilm to be that knowledge that was built and developed upon these fundamental basis. As a matter of fact, Islam considers the purpose of knowledge as bound to knowledge about God, His Divine Power, and His All-Mighty Wisdom. The result of knowing God is love for God, and the result of this love is spiritual happiness. Given this reality, Muslim scholars and scientists do not feel anxiety and hopelessness, for as they pursue their studies, they discover new existences, feel closer to God, and varying degrees of spiritual peace. For those who study the universe from such perspectives, knowledge is the way to reach material and spiritual happiness; for those who follow the path of materialism, knowledge can become the way to see the undesired consequences of existence and the final end of the universe. Such knowledge will cause them to be in a state of constant unhappiness.

For those who do not know The Most Merciful and The Most Compassionate Lord of the universe, the sun will burn out in 5 billion years. Such knowledge will spread fear into their hearts, for they will think that œafter the sun burns out, the horrible end of the worlds will begin and we will dissolve into atomic pieces and face non-existence. They will suffer from being a part of this universe. In short, following a materialistic approach to science results in hopelessness, fear, and disappointment. At this point, knowledge (in the Islamic context of this world and the Hereafter) gives confidence, and science (in the materialistic context of being limited to what the five senses can perceive) gives hopelessness. Thus, the two contradict each other. Those who follow the path of knowledge, by His help and guidance, always will walk in enlightenment and will never be disappointed or have doubts about the future.

In order for such things to happen, all of the aspects of knowledge (ilm) and science must be taken into consideration. That is why many modern scholars and scientists are trying to change and direct existing materialistic theories and approaches toward the Islamic understanding of knowledge and science. A number of them are convinced that the contemporary Western approaches are based upon unbelief and that they cannot be changed. If materialistic science makes no effort to find God, and if it does not strive to become a mirror showing His Divine Beauty, humanity’s future may be unexpectedly dramatic.

In our increasingly diverse societies, we interact with people of different faiths. At times, this poses a great challenge: something deeply sacred and true for one faith might be in stark contrast with what is true in another religious tradition. How can we share our values in such a way that the true messages of our different faiths benefit people from other religious traditions? Interfaith dialog is a means for achieving this greater goal by persons of different faiths meeting to have a conversation. But dialog is not debate. notes Leonard Swindler. In dialogue, each must listen to the other as openly and sympathetically as s/he can in an attempt to understand the other’s position as precisely and, as it were, as much from within, as possible. Such an attitude automatically includes the assumption that at any point we might find the partner’s position so persuasive that we would have to change. There is a need to recognize that differences do exist and the objective is not to correct but to hear and listen to the other side.

Religion is usually cited as the cause of or at least a factor to conflict around the world. Drawing upon the experiences of the contributors, the goal of Interfaith Dialogue and Peacebuilding is to identify the ways in which we can engage in productive interfaith dialogue. Rabbi Arthur Schneier, one of the contributors of the book, points out that religion is never the real cause of conflict within or between societies, but it is often identified as an excuse for other causes such as ethnicity, economic disparities, and regional differences. The main assertion of the book is that interfaith dialogue can be used as an effective tool to advance peace building around the world.

Based on his experience and studies on conflict resolution, Professor Mohammed Abu-Nimer identifies four phases of development in an effective experiment of interfaith dialogue. He suggests that the earlier encounters should focus on individual and group similarities in theologies and scriptures. One example could be to jointly study the sacred texts of each religion. It must be remembered that the goal for these studies is not debate or conversions. Professor Marc Gopin notes that these shared studies should yield deeper bonds through invitations to homes and meetings with families. The second phase is to deepen the relationship through joint prayers that are not contradictory to the other faith and by participating in the other faith’s rituals. Having established trust and an understanding of the other faith, the third phase is to discover and confirm differences in religious values and faith practices. The final step should be exploring the ways in which messages of different faiths can benefit people from other religious traditions in the same community.

Articles in the book encourage us to re-think elements within our religious traditions that call on us to engage in interfaith dialog. It encourages us to breakdown stereotypes we have of the other faiths and reflect critically on the practices of our co-religionists. Contributors’ experiences show that in order to be effective, talks should be accompanied by deeds. As Professor Diana Eck affirms One world cannot be built on the foundation of competition and polarization between the superpowers. One world cannot be built on the foundation of science, technology and the media. One world cannot be built on Christian, Muslim, Jewish or Sikh triumphalism. One world cannot be built on the foundation of fear and suspicion….Laying the foundations of one world is the most important task of our time. These foundations are not negotiated statements and agreements. These foundations are, rather, in the stockpiling of trust through dialog and the creation of relationships that can sustain both agreements and disagreements.

Within this framework, servants become engrossed in a combined feeling of fear and hope. Away from the sight of others, we supplicate from the heart only to God, and pray in secret. This sentiment, which is reflected in The Qur’an 7:55, describes an essential element of prayer that we must observe while praying. However, only the Legislator can permit and encourage this attitude at various times, and only He can determine the degree to which it is allowed.

God enjoins us to pray to Him only, in fear as well as full of hope and to know that His Mercy is with those whose hearts beat with the consciousness of His constant supervision over them. (7:56) He even shows us the door toward which we should walk, and teaches us the rules and principles of how to wait in front of it.

Turning to God all the time and in every condition, opening our hands in supplication, and revealing our concerns and problems to Him are all an honor and an initial prize. In addition, they are very significant initial steps taken to earn a favorable response from Him. He states: If my servants direct their wishes to Me, they must know that I am closer to them than anything else. I respond to the prayer of those who turn to Me with prayers. (2:186) However, there is a condition: All of these prayers and supplications are to be performed as indicated in: You pray from the heart with utmost sincerity and seeking God’s pleasure. (7:29, 40:14, 65) Instead of praying when among people, as if showing off to others, we should entreat the All-Knowing God, Whose hearing and seeing is worth far more than any person’s, by sighing in secret and with utmost sincerity, in complete privacy so that we are closed to others but open to Him. Meeting these conditions will enable us to implore Him with the alchemy of secrecy, and will prevent our voices and sighs from being fouled with the sparks of irrelevant thoughts.

No one returns empty-handed from His court. In fact, those people who pour out their deepest needs and desires, and present such personal grievances about themselves only to Him, are drawn closer to Him. They have to ask the One Who can meet all of their needs, just as they have to complain to a doctor who can heal their illnesses.

Each servant who enters the Nearest One’s Presence is required to be in possession of his or her self and in full control of his or her speech, vocal vibrations, and groaning. Moreover, each servant’s mind, intelligence, and senses must be in a receptive state.

Loyal servants frequently filter their thoughts and supplications through their intentions and sincerity, for they strive to keep their expressions and feelings free of any disturbance. They become like mute people so that no one can hear them, to such a degree that they even become jealous of their own voice and words.

In addition to being sincere while praying, servants should search for moments and seconds during which their pulses beat with the remembrance of God. They should make full use of holy days and nights, for these are the times when divine blessings pour forth. Especially when it is time to pray and to break the fast, all prostrations and bows should be performed in such a way that not even one second is wasted. Loyal and sincere servants are expected to fulfill these obligations, for doing so is essential for the prayer to be accepted. As all such servants know, a prayer may be answered either positively or negatively, or circumstances may ‘become’ favorable or unfavorable.

Believers in God do not mind if summer is as cold as winter, if spring seems to resemble autumn, or if days become as dark as blind graves. Who cares about darkness when God reminds us of His All-Encompassing Power: Who saves you from the darkness of the land and the sea when you pray in destitute?! (6:63) Who cares about such things when God makes His Existence known in their conscience by saying: Who else, other than God, accepts the prayers of the poor and takes care of their problems?! (27:62)

The Qur’an is the Divine Book that guides us through existence, interprets events, and interprets both the macro- and micro-worlds. It is the language of the World of the Unseen in this life; a contract of divine blessings for humanity; and the essence, essential nature, glory, and light of Islam. As if that were not enough, it is also the map for the worlds of the afterlife, a means of happiness for believers, and a book of prayer.

The Qur’an introduces a prayer by glorifying Him, and then asks to be set on the straight path as it sets off, sprinkling its most brilliant jewels with Surat al-Fatihah. Next comes Surat al-Baqarah, which calls us to pray by means of implicit expressions of prayer, raising its voice with the tune of its explicitness, and teaches us what to ask from God: Our Lord! Grant us good in this world and good in the Hereafter (2:201). After a few pages, it shows us the greenhouses and shelters in which we can shelter while facing difficult conditions and asking for help: Our Lord, pour down upon us patience (endurance), make our steps firm (make our foothold sure), and help us against the unbelievers (2:250).

The last verse of this surah points to the following prayer, which is a gift from the Prophet’s Ascension and which should be repeated constantly: Our Lord, do not punish us if we forget or make a mistake. Our Lord, do not lay on us a burden as You did on those before us. Our Lord, do not impose upon us that which we have not the strength to bear. Pardon us and grant us protection, and have mercy upon us. You are our Patron, so help us against the unbelievers. (2:286)

The next surah, Surat Al-i ‘Imran, also starts with and reminds all believers of a very significant prayer: Our Lord, do not let our hearts deviate now after You have guided us. But grant us Mercy from Your Presence, for You are the Grantor of bounties without measure. (3:8) A few verses later on, we are invited again with an allusion to the prayers of the pious, who supplicate with the following cries: Our Lord, we have indeed believed. Forgive us, then, our sins, and save us from the agony of the Fire (3:16) and: Our Lord, we believe in what You have revealed and we follow the Messenger, so write us down with those who bear witness. (3:53) These draw our attention to the supplication of Jesus’ apostles, who also are filled with a sense of responsibility.

Right after this comes a gift of prayer from the mouths of the devout ones, the scholars who gathered around the Messengers and strived: Our Lord, forgive our sins and anything We may have done that transgressed our duty. Establish our feet firmly, and help us against those that resist faith. (3:147) The section of contemplation toward the end of the surah ends with a wish for a good end: Our Lord, lo, we have heard a crier calling unto faith: ‘Believe in your Lord!’ So we believed. Our Lord, therefore forgive our sins, blot out our evil deeds, and make us die the death of the righteous (3:193). Those who shake fearfully, thinking that they have treated themselves unjustly, pray: Our Lord, we have wronged ourselves. If You do not forgive us and have mercy upon us, surely we are of the lost (7:23) and remind us through a distinctive cry that unleashes tremors into our souls. Our Lord comprehends all things in knowledge. In God do we put our trust. Our Lord, decide with truth between us and our folk, for You are the best of those who decide (7:89) whispers a unique style of entreaty of a submissive Prophet who murmurs ‘establishment of justice’ with full confidence, asking for God’s action against an extremely impertinent disbelieving society.

In accordance with the context, the Qur’an frequently presents examples of the Prophet’s supplications, sighs, and pleas for help. For example: You are our Guardian, therefore forgive us and have mercy on us (7:155); O our Lord, do not let us be subjected to the persecution of the unjust people (10:85); and There is no god but You, glory be to You. Surely I am of those who make themselves to suffer loss. (21:87) Hundreds of Qur’anic verses call us to interrogate ourselves, plea, and complain about our evil features. Such verses reveal that prayer is a source of strength for those in charge, a fountain of absolution for those who have committed sins, a solution for the needy, a hand extended to help those struck by disaster, a key to a treasure for the poor, a doctor for the sick, a breeze of hope for the desperate, and a dispatch order of a gift for the oppressed and the victim. The Qur’an always points out that prayer and humble supplications lead to salvation from worldly problems and concerns with the Hereafter, and that those who see (the Book) with the heart and murmur with the soul are traveling toward and praying to God.

In parallel with the Qur’an’s prayer-colored horizon, the life of Prophet Muhammad, the sultan of prayer, is a lacework adorned with entreaties and supplications. He would open hands, turn to his Lord, overflow with thanks and glorification, bow and double himself up in prayer, and constantly supplicate to Him. He did this throughout his life: when he woke up in the morning, lived until the evening, and stood in God’s Presence at night; while performing the ritual ablutions and daily prayers, observing these prayers (each a heavenly ascension), listening to the call for prayer, and during and after each prayer as a means for getting closer to God; while eating, going to bed, traveling, returning from a campaign, confronting an enemy; and while experiencing worldly or heavenly disasters and surprising events, witnessing miraculous events, suffering from illnesses or troubles, and when concerned or pleased with something. Prayer books give more details about all of his prayers and supplications.

Prayer is a mysterious key to His everlasting treasures, a point of support for the poor and hurt, and the most secure shelter for those in distress. Those who step into this shelter are considered to have obtained this key, and the poor, weak, and needy who join this governance attain that for which they had hoped.

The inhabitants of the heavens carry along the sincere prayers of such needy people, who are deprived of any other solution. These destitute people, who are in a state of desolation and demise, know what they are asking for and are aware of what they are doing. They turn to Him and unburden themselves of all thoughts. Such prayers would make the heavens burst into tears; hurricanes threatening the world would change its course, waves overturning everything would calm down, and peace would rise on the horizon. Broken fault lines would surrender to unexpected rulings, and released gases would easily evaporate into the atmosphere. The breeze of such a prayer enlivens Earth and brightens the skies. Hearts beat with exhilaration, and nature rises in order to dance and to send forth smiles.

Through prayer, people offer their sacred requests, which are beyond causes, to the Most Glorified One, and acknowledge that God see whatever is hidden or open. Humanity, as well as the jinns and the angels, pray to Him, especially about issues that subjugate their strength and control, and expect a remedy from Him. However, such a remedy is forthcoming only if we take all of the required measures and fulfill all of the necessary conditions.

O Remedy for all in need! Send a light from Your presence for those suffering in darkness, especially these days, when there is no means left to resort to, social circumstances are in complete disorder; when only the tyrants’ voices are heard everywhere and the people sway and bump into obstacles. Extinguish the fires of tyranny and injustice with Your Infinite Power, destroy the Devil’s homes, and place inescapable collars around the necks’ of the evil ones.

We are not exposed to the winds of inspiration any more, the enthusiasm in our hearts has been subdued, and a stammer has started to appear upon our tongues. Send us a reviving breeze from Your land of mercy. Raise our hopes and goodwill for You to the borders of Your Mercy, give us faithful excitement, and accept us as hopeful supplicants thereof. Untie our tongues so that we do not commit another sin.

We are wronged, fallen, and devastated. Never have we been so far from You. Never have we entered such depths of failure. Never have we been so without You.

O Shelter for the miserable, Power Source for weak, Physician for the ill, and Truthful Guide for the lost! Once more we take refuge in You and unburden ourselves to You. We have been chasing after useless things and longing for the fulfillment of ridiculous dreams. Those whom we approached with hope and in whom we trusted never even looked at or paid any attention to us. No one but You have heard our voices and caressed our heads. Our feelings have been mocked, and our thoughts have been regarded as crimes. So many places have been sabotaged, fires of mutual separation have been inflamed, and all of what has been committed now hurts the purity of the faith.

Broken-down feelings, clumsy behaviors, souls in the dirt, feeble feet, paralyzed hands ‘ most of us have lost all hope ‘ the weather is foggy-gray ‘ people in the West are filled with longing ‘ people in the East are in need of Your blessings. We have come to You in such chaos. We are neither the first nor the last to come. Your Mercy is the door of hope for those who regret, and we are pitiful beggars in front of this door. Until now, all who have waited by Your door have returned with a blessing, and no fugitive or repentant person has ever been rejected. It is Your door, and thus it differs from others because only it opens upon the forgiveness that You bestow upon all those who wait by it. Strengthen us with Your mildness and peace. Make Your Existence heard by the tyrants.

O the Sultan of the exalted throne Who answers all prayers! Thousands, hundreds of thousands of us stand in Your Presence now. Opening our hands to You and knocking upon Your door of mercy, which is always open or at least ajar, we sigh. We believe from the depths of our hearts that You see and watch over everyone and everything, that You show compassion for every praying voice and person. Therefore, we ignore our disobedience for the time being, imagine our sins washed away in the falls of Your Mercy, and disregard our faults while regarding Your forgiveness. If You exist ‘ You are the only One who exists on its own ‘ we cannot be deserted. If You are our companion, then who cares about the wilderness that surrounds us on all sides?! As long as You are together with us, it does not matter even if Satan and his followers are everywhere. You are the one and only Sovereign over everything, and Your ruling cannot be overthrown. You see the smallest thing, hear the most silent sound in the domain of Your Sovereignty, and do not discard anything or anyone without a reply.

Yet again do we present ourselves at Your door, which is as large as Your Mercy, with the capacity that You have given us to ask from You, and with the belief that You will grant us our wishes. You know our situation, and so what we are going to tell You is just a small part of Your Knowledge. Give us a remedy for all the troubles that we have suffered from for centuries. O Most Merciful, Most Compassionate, accept our prayers!

In his Models of My Life, social scientist Herbert Simon stated that science’s purpose is to find meaningful simplicity in the midst of disorderly complexity. Although the systems in nature and society seem to be very complex, we need simple theories to understand them. The key to finding these simple rules or principles, which Plato called perfect form and thing-in-itself and Kant described as a kind of untouchable essence behind physical things or systems, is mathematics.

Mathematics and social science

One of mathematics’ main challenges is its uses in social sciences. But does mathematics, which is considered rigid and restrictive and the best tool for explaining matter, have laws for human life? The latest studies in sociology, biology, and epidemiology show that such laws and meaningful patterns do exist and can be discovered. One of the great achievements of mathematics and physics in sociology is explaining the six degrees of separation (i.e., the small world) phenomenon.(1)

Almost everyone has met someone far from our home who is a friend of a friend. This is so common that it has become a clich: It’s a small world “ even though there are now more than 6 billion people. Even more surprising is the structure of social networks, the map of who knows whom, which shows that all people are closely connected.(2)

A social network is a collection of people, each of whom is acquainted with some subset of others. This can be represented as a set of points (nodes) denoting people, joined in pairs by lines (edges) denoting acquaintance, in a company, university, or even a global community. Social scientists have studied such networks, both empirically and theoretically, for at least 50 years.

A revealing experiment

One of the first and famous empirical studies was conducted in 1967 by Stanley Milgram, a Harvard psychology professor: the small world phenomenon. He asked: Starting with any two people in the world, what is the probability that they will know one another? In a large social network, although X and Z might not know each other, they might have a mutual acquaintance. Moreover, X might be linked to Z by a series of links. In other words, X knows a, who knows b, who knows c … who knows y, who knows Z. But how many intermediate acquaintance links are needed, on the average, to connect X and Z?

According to Milgram (3), this phenomenon raises the issue of a certain mathematical structure in society, one that often plays a part in discussions about history, sociology, and other disciplines. For example, during western Europe’s Dark Age, cities became isolated because inter-city communications broke down and thus severely limited the network of individual acquaintances. Thus, social disintegration was expressed in the communities’ growing isolation and people’s infrequent contact with non-local people.

Milgram asked his test subjects, chosen at random from Nebraskan and Kansan telephone directories, to get a letter to one of his Boston stockbroker friends. The letters were to be sent passing them from one person to another, but only if both parties were on a first-name basis. Since it was unlikely that the letter’s initial recipient and a Boston stockbroker would be on a first-name basis, their best strategy was to pass the letter to someone whom they felt would be socially or geographically closer to the stockbroker.

A moderate number of the letters eventually reached their destination. Milgram discovered that the average number of steps in this process was about six. This is usually considered evidence of the small world hypothesis: Most pairs of people, even in a very large population, can be connected by a short chain of intermediate acquaintances.

Milgram’s work passed into folklore and was immortalized in John Guare’s 1990 play Six Degrees of Separation, where Ouisa claims: Everybody on this planet is separated by only six other people. Six degrees of separation. Between us and everybody else on this planet. The president of the United States. A gondolier in Venice…. It’s not just the big names. It’s anyone. A native in a rain forest. A Tierra del Fuegan. An Eskimo. I am bound to everyone on this planet by a trail of six people. It’s a profound thought…. How every person is a new door, opening to other worlds.(4)

Watts and Strogatz used this model to explain the six degrees of separation in society- and nature-based networks.(5) Their model employs mathematical graph theory, which consists of nodes (people) and links (acquaintance). They modified the regular network, in which every node has short-range fixed number of connections, by adding long-range connections to the regular network to simulate the short path length between nodes. This model is now used in such areas as networks connected with biological metabolism, genomes, proteins, the Internet backbone, power grids, companies, and the stock market.

Research on social networks has helped health professionals understand how epidemics spread. Epidemiological models help them to predict how fast a disease will spread and to develop small world theory strategies to combat them, for scientists now realize that this social network property is a main cause for the outbreak of epidemics. This network offers a super-connected web of stepping stones for infectious diseases. After analyzing the social network’s structure, public health specialists can devise new vaccination strategies to slow or stop the epidemic. The small world theory also explains the rapid spread of news, rumors, fashions, and gossip.

Other types of systems show similar properties: networks of actors involved in the same movie, scientific collaboration networks of scientists who coauthor an article, and even the Internet, where millions of web pages are connected via mutual links. Recent research shows that in all of these networks, there are only a few steps between one node and any other node. The average shortest path between a network’s nodes, is 3.5 for the actor network and 9.5 for the scientific collaboration network. Despite the Internet’s more than 800 million nodes, there are, on average, only 19 steps between one web page and any other.(6)

Conclusion

The small world theory is a great success of the theory of complexity in nature and social life. It reveals an underlying dynamic of interconnectedness that expresses itself indelibly in who we are and how we think, behave, and communicate. Such close interconnectedness reveals one important fact for constructing a peaceful and beneficial world: There are no strangers, for everyone is one of our friends’ or neighbors’ friend or relative. The key element in understanding people is communication. Mutual love and good relations continue as long as we understand each other. We are loyal and faithful to the extent that we share our friends’ troubles, because ignorance only builds an impenetrable wall between us.(7)

But two important developments in modern physics during the 1930s gradually undermined their certainty. These developments were based upon experimental, intellectual, and theoretical observations. The experimental field revealed new particles, and the relevant tools and techniques became far more sophisticated. The results showed that subatomic components were not elementary particles, for they were not even elementary. And, the number of fundamental particles continued to grow: 6 in 1935, 18 in 1955, and more than 200 today.

Subatomic particles challenge old assumptions

Classical physics held that an object’s mass was connected to an elementary material that could not be annihilated or divided. But Einstein’s theory of relativity disproved this by showing that mass was not related to a concept like essence, and that energy was an expression of a quantity associated with activity, process, and movement. Since a particle’s mass is equivalent to a specific energy, the particle cannot be a static and stable object. Thus, a particle’s mass has to be considered a dynamic entity. This energy process shows itself as mass.

The theory of relativity’s most interesting aspect appeared when the process of extracting matter from pure energy was explained. Given that matter’s elements were considered indivisible and non-changeable units or compounds that could be reduced to their origins, could matter be fragmented ad infinitum or would the smallest indivisible unit eventually appear? The theoretical physicist Dirac (1902-84) answered this question by showing that when two particles collide at a high speed, they generally are smashed. However, the residual pieces are not smaller than their originals, for these remnants are constituted as the same particles via kinetic energy.

Subatomic particles are split by using high energy levels to crash them into each other. Thus matter can be split forever, and no particle so obtained can be smaller than its original. Such collisions result in new particles, for the two colliding particles’ energy is delivered between the particles so that new ones are formed. If there is enough such energy is produced, more particles are constituted than before the collision, meaning that subatomic particles are both divisible and indivisible.

As this is one of the best ways to study a particle’s basic features, this field is called high energy physics. The necessary kinetic energy is obtained by using particle accelerators, which are a couple of miles in diameter, to accelerate protons almost to the speed of light and then crash them into another proton or neutron. It is interesting that such huge super-microscopes are used to analyze infinitely small objects.

Since 1960, the number of known subatomic particles has grown. There were electrons in the nucleus, and protons and neutrons in an atom’s orbit. But what was in the proton? In 1970, Swiss researchers discovered a quark in the protons and neutrons. Its electric charge was explained by the charge value of protons and neutrons. But they could not explain what the energy was. Energy, which chained the quarks forming the proton in the nucleus, was called the strong nuclear force. But how could this energy bind the quarks together? Scientists postulated that energy was not an invisible force, but a feature formed by tiny granules and motes. Thus, these gluon (adhesive) particles bound the quarks together by pasting and clamping them in such a way that nuclear power was developed. In other words, the essence nuclear power was the gluon.

Photons, defined as particles carrying electromagnetic energy, were postulated to be the result of an exchange, a shifting between two particles. Thus, electromagnetism was a field of quantum, carried its energy through particles with no electric charge, had a spin value of 1, and was not radiating but rather perceived. Although photons had been known for a long time, scientists did not realize that they provided the force of attraction between protons and neutrons. Photons were the smallest energy packages forming the light. Now, the only thing left to be discovered was the weak nuclear force that controlled radioactive decay.

These forces had to be carried by particles. These particles (bosons), when discovered, were found to be of three types: positive (W), negative (W), and neutral (W). Thus, scientists learned that the universe’s three elementary forces were carried by particles. But the particles (gravitons) carrying gravity, the weakest force, remained undiscovered. 

Non-atomic particles

Non-atomic particles are depicted as objects having a mass in terms of space, and as events and activities having as much energy as the quantity of the mass. Given this, the matter found in space is unstable and changes due to continuous activity and movement. This is surprising, for it means that particles move and consist of movement. In other words, matter’s presence and movement are not different of each other, but represent different features of the same mechanical truth.

Based on these observations, particle physicists consider force to be an energy transition between matter, which it affects, and think that it is caused by the smaller particles’ diffusion and absorption. For instance, charged particle’s state of movement changes when it diffuses a photon. If another charged particle absorbs the photon, it gains energy and thus changes its condition of movement. Here, as the mutual movement changes between two particles occur as force, the change’s total effect is perceived as force. And so there are no external forces, but only interactions via some inter-particles between the particles. In this way, quantum mechanics adds an unusual approach to non-atomic events and engenders a completely different description for force. In fact, force does not exist, because it is no more than tiny particles, motes, and rays. So, the interaction and continuous communication between particles give rise to force, which has no reality or presence by itself.

This truth disturbed materialists and determinists, for it showed that matter and force, which brought forth and sustain this magnificent universe, are based on another existence that indicates omnipotence. According to Said Nursi, the existence of this power is more definite than the existence of the universe, and each visible item is a proof and the sign of the Holy Power of God, the source of all objects and forces. He states: Every creature, either on its own or altogether, is this Power’s solid word. Scientific names like ˜dynamic process,’ ˜energy form,’ or ˜effect mechanism,’ are given to this governing power. However, modern science is beginning to show that the effect mechanism, which cannot be associated to any reason and is reduced to one truth, is really the manifestation of the ˜Holy Power.’ Said Nursi further says The motion of particles is the vibration and motion from that writing and transcription, which occurs while beings pass from the World of the Unseen to the Manifest World, as they pass from knowledge to power. (The Words, Vol. 2, 30th Word, Second Aim, Footnote) 

Conclusion

In conclusion, the activities and creation of creatures are manifested as wave-vibration-movement passing from the field of knowledge to the field of power. Then, the pen of Divine Power writes its fate and ushers it into the world of material existence.
