Asteroids and Comets

At the time when the proof that such an occurrence had already taken place on Earth was first discovered in the early 1980’s, there was a threat of a similar crash. The American physicist Luis Alvarez and his son William proposed the hypothesis that about 65 million years ago (at the end of the Cretaceous period), as a result of a meteorite hitting the Earth, the climates had changed altogether and that this had led to the extinction of many land and marine species. According to this theory, which is supported by fossils found throughout the world, approximately 65 million years ago, when a meteorite almost 10 kilometers in diameter hit the Earth, a cloud of dust formed, leaving the Earth in darkness for years; the result of this was that rays of the Sun could not reach the Earth, thereby preventing photosynthesis, and consequently the possibility of plant life. This in turn led to a chain reaction, eventually leading to the extinction of some animal species (including dinosaurs) that fed on plants and other animals. The cooling of the air, the poisonous gases that filled up the atmosphere as a result of forest fires, and the rising of the acidity of the subsequent rain might all have played their roles in the extinction of land and marine animals. It seems that 8 out of 10 species disappeared from the face of the Earth in a few thousand years, or even less. The traces of the meteorite crash can also be seen in the iridium levels found in sediments from the Cretaceous-Tertiary boundary (This metal from the platinum group is found in small amounts on Earth, whereas in meteorites it is in abundance). In the quartz crystals that had undergone shock it was visible that they had been subjected to high pressure due to a crash; the nickel minerals showed that a nickel-rich meteorite had been oxidized in the atmosphere. The location of the meteorite crash was found in 1991. On the shores of the Mexican peninsula of Yucatan, under a one kilometer stratum of sedimentation, a crash crater with a diameter of 260 kilometers was discovered through gravimetric methods. Its age was found to be 65 million years. Another factor that could have led to great amounts of carbonic gas and sulfur oxide being introduced into the atmosphere would have been intense volcanic activity, which it is understood took place at the end of the Cretaceous period; this too could have contributed to the degeneration of the climate.

This was not a one-off incident. Approximately 445 million years ago (at the end of the Ordovician period) gamma rays from space could easily have been the cause of a mass extinction of two-thirds of all species on Earth. Gamma-ray explosions are the strongest explosions known. When huge stars implode into black holes at the end of their lives, they emanate very strong gamma rays as pulses at a particular frequency from their poles. If such an explosion should happen in our galaxy and should the rays head toward us, it would be very destructive indeed. It has been understood that species like “trilobites,” which continued to live very close to the ocean surface suffered great losses during this period. This could be explained only by the occurrence of a gamma ray explosion, which would affect the creatures on land and the ocean surface, but would not greatly trouble the deep-water creatures (Hecht, 2003).

Around 250 million years ago (the Permian-Triassic boundary), as a result of another mass extinction, probably 90% of marine species and 705 land species disappeared from the face of the Earth. These extinctions were attributed to the rapid changes in the climate and sudden changes in sea-levels or intense volcanic activity. To these factors was added the “cosmic cause.” In the rock sediment specimens of this period, the isotope distribution of helium and argon gases was more similar to the distribution in meteorites than to that of the rocks on Earth. In 2001 American geochemists and Australian geologists found new evidence concerning the meteorite crash.

In the 1990’s, astrophysicists understood that the balance in the solar system was very sensitive, and that it was impossible to predict the long term orbit of a heavenly body. Apart from the regular movements of planets and their satellites, innumerable comets and asteroids, at various angles to the system, are engaged in rotating motions which are impossible to pre-calculate. In 1996, the Shoemaker-Levy star fell onto Jupiter bit by bit, tearing away balls of fire as big as the Earth. So, what sort of objects can hit the Earth?

Andromeda, the closest galaxy to ours, is coming toward us at a speed of 400,000 kilometers per hour. But because it is two million light years away it is set to collide with our galaxy only five billion years later (if Doomsday does not arrive before then!) According to the information we have today, since the neighboring stars change their positions along with the Sun within the great circular movement of the Milky Way, the possibility of crashing into one of these is nearly non-existent. The planets in the solar system give us no reason for concern either. Their orbits, in which they have been excellently placed, do not intersect with that of the Earth. The Moon does not present a threat either. It is also not anticipated that any machine parts from satellites will reach an acceleration that could be disastrous as they enter the atmosphere. What threats remain are asteroids and comets that have a tendency to hit the Earth.

Asteroids are large objects that have a rock-like structure, yet are not big enough to be considered planets. Their diameters range from a couple of meters to 30 kilometers. Many asteroids that are close to us move in orbits that intersect those of the Earth. Asteroid 3753 (1986 TO), which has an orbit that has a dynamic relationship to ours, seems to be another satellite to the Earth, along with the Moon. (Wiegert et al., 1997). Comets, on the other hand, are balls of dust that have heated up as they pass close to the Sun and are adorned with bright tails. The possibility of a crash stems from these two groups. These comets revolve around the Sun in specific orbits, and it is without a doubt that they have a great significance for the system; these objects are concentrated in three major areas. The first area is a large belt between Mars and Jupiter (The Asteroid Belt). Here there are approximately a million asteroids of diameters greater than a kilometer. Further away, beyond Neptune, in the Kuiper belt, whose size is 30-100 times greater than the distance between the Earth and the Sun, it is believed that there are more than a trillion comets. Another source of meteorites is the border area of the solar system, which opens up to wider space, the sphere shaped Oort Cloud, whose diameter is 40 thousand times greater than the distance between the Earth and the Sun. (Poirier & Greffoz, 2001)

When we consider an asteroid of a kilometer in diameter and which is further away than Mars, it hardly seems bigger than a grain of sand 100 kilometers away from Earth. In 1998, NASA started a project which aims to use telescopes to identify (within 10 years) 90% of the asteroids of more than a kilometer in diameter which are moving toward Earth.

Unity in Abundance

The solar orbits of those distant bodies that cannot be identified can be disturbed by even the slightest intervention. It is enough that the orbit of an asteroid should be ever so slightly disturbed as it passes near one of the satellites of Jupiter for it to leave its orbit and start heading toward us. Our existence is bound to such vast Compassion, manifesting itself in such a fine equilibrium; this only goes to demonstrate to us that it is only He Who protects us to Whom we should be grateful, not only for our Creation, but also for every step of our life and every breath; it is He Who is Alive and Who is the Source. On the other hand, our condition of being human and our responsibility to look after what has been given into our keeping spurs us to search for apparent causes in this world. Since we do not know when or why our deaths will come upon us, we take precautions against situations that may be dangerous and try to stay alive; in the same way, as we do not know when Doomsday will come nor what its apparent cause will be, we must take precautions against risks like meteorites (without forgetting that the real affect and the final will lies always with God) in order to protect life on Earth. But we do not know what the scientists (and authorities with executive powers) who have the means to monitor the Universe with well-developed equipment feel; and with what feelings they inquire into the nature of these meteorites. We wonder if they are aware of the fact that the meteorites are in the Command of the One and Only, as are the Sun and the Earth and, indeed, the whole Universe. Can they acknowledge this fact openly, without feeling the psychological terror that the science of the “denying school” imposes? Can they see the falsity of using the word “threat” for meteorites?

What Sort of Measures for What Sort of Life?

Asteroids can reach a speed of 100,000 kph, while comets can get up to 150,000 kph. Even if the mass may be small, at such speeds a great amount of energy is produced. According to Brian Toon of Colorado University, if a meteorite crashes on to the Earth, the surface of the Earth will catch fire and the sky will be filled with very hot particles that are lifted from the ground (Hecht, 2002). The amount of damage that the crash will cause to humanity is dependent on whether the meteorite crashes into the middle of the ocean or into a city. According to researchers, if the diameter of the meteorite is less than 300 meters, then the people living in the probable crash site should be evacuated. If the meteorite is quite large, then one should send a rocket with a nuclear head toward it in order to blow it up and try to diverge it from its orbit. But this intervention could be risky; the energy of the rocket could be less than needed, and the radioactive shower could fall back down to Earth. Other options, like using rockets without nuclear heads or other asteroids, exploding the meteorite with lasers or trying to decrease its size through piercing it with drills could be attempted. But all these are technologically impossible today. It is not even known whether the time between the determination of the body”s approach toward the Earth and its probable crash time will be enough for us to determine what to do. In the worst case scenario, a great crash and massive deaths could be the result. The probable destructive force of these objects can be inferred from nuclear tests that have been carried out. But the determination and analysis of occurrences in the past has proven to be difficult. Since three-quarters of the world has been covered with water for billions of years, the traces of crashes under the seas and the oceans do not remain, and the crash sites on land are eroded away, sometimes even as quickly as in a couple thousand years.

Other Possibilities

So is there nothing else that can fall upon our heads? For instance, anti-matter. Anti-matter is composed of antiparticles, which are just like ordinary protons, electrons, and neutrons except they have opposite electrical charges and magnetic moments. When antimatter and matter collide, both are annihilated. The existence of anti-matter in the universe has been demonstrated by particle accelerators. The entry of anti-matter the size of a pebble into the atmosphere could be enough for matter and anti-matter to disappear in a great whirl of energy, greater than the one caused by the Hiroshima bomb. We cannot even imagine what would happen if an anti-meteorite with a diameter of a kilometer should hit the Earth. Nevertheless, the French astrophysicist Marc Lachièze-Rey said: ‘Had there been an anti-matter asteroid in our galaxy, it would emanate x-rays when it disappeared with the material it had around it.’ Now let us get back to usual asteroids. There was the greatest crash of the 20th century, which took place in June 1908 in Tunguska (Russia). It is believed that there a small asteroid cleared 2,000 km2 of Siberian forest. A similar incident was the strange explosion that lit up the Jordanian sky, shattering the rocks in the area on 18 April 2001. It is believed that the 100 km2 diameter of the Popigay crater in Siberia was caused by a meteorite (Bottomley et al., 1997). In the last eight years US satellites that look for nuclear explosions have determined nearly 300 optic blazes were caused by small meteorites (diameters of 50-100 meters). According to Bill Napier from the Armagh Observatory in Northern Ireland, comets present a greater danger. Comets with tails composed of gas and dust and with structures of ice are much rarer than those with a rock-like structure, and they may damage the Earth in different ways. A comet that evaporates under the rays of the Sun would leave billions of particles of dust in the orbit of the Earth. If the dust were to shower down onto the Earth, it could block the rays of the Sun from reaching the Earth, thus triggering the start of a new ice age. There are still four known objects in space with diameters of more than a hundred kilometers that are believed to be comets. There may be 2,000 more in the Oort Cloud, beyond Pluto (Samuel, 2001) In short, there are many objects moving around our planet that could end our life, and yet, life on Earth has continued for billions of years.

He Makes Us Live and Die

On the other hand, after a crater caused by a meteorite cools down, life can regenerate. Devon Island in Canada is a polar desert on which there are no plants and animals. There, the Haughton crater, with a diameter of nearly 24 kilometres, is believed to have been caused by a meteorite crash that happened 23 million years ago. As far as we can gather from fossils and other traces, there were probably thick forests in this area; the forest was lost and the shock wave that took place here destroyed most of the other living things with an explosion and the subsequent heat. About a thousand years later, life came back to Haughton. The subterranean waters were heated as a result of the crash, thus presenting a perfect living environment of hydrothermal systems for organisms that live in colonies, such as bacteria and algae. This activity has been observed in 70 of 170 crash craters. It is not know when life was created, but the first traces go back nearly 3.8 billion years. That is to say, the Earth might have been full of these hydrothermal systems at the beginning of its creation. The craters on the Moon, on the other hand, show us that meteorite crashes in the past were 15 times more common (Osinski, 2003). Thus it is impossible to explain, through reason, how life could have been created in a period of our world when it was—apparently—extremely unfavorable for life. There are other influences that reach the Earth from space. About a thousand years ago the Earth was going through its last ice-age. The Aquila star constellation, which can be observed from the Northern Hemisphere, probably went through an intense upheaval and emanated radiation in great amounts in all directions. This wave of high energy traveled through space for 20,000 years, hitting the Pacific Ocean on the evening of 27th August 1998. As far as it could be recorded with terrestrial and orbital observation, on that summer night the Earth was bombarded with gamma and X-rays for five minutes. The radiation scattered as it reached the lower strata of the atmosphere. A greater energy could have reached the Earth from interstellar space and caused destruction of matter. It is believed that this incident that took place in 1998 was caused due to the tearing up of the surface of a ‘magnetar’; this is a sort of a neutron star. It is believed that that magnetar was of a diameter measuring 35 kilometer, but denser than the Sun; a thimble-size portion of it would have weighed as much as 100 million tons. This star revolved around itself like all neutron stars and as a result created a great magnetic field. If this magnetar had been only 10 thousand light years away then the energy that reached the Earth would have been four times greater; it may have been strong enough to damage the ozone layer (Ward & Brownlee, 2000).

Conclusion

At the start of the 19th century, Georges Cuvier, a French palaeontologist and a practicing Christian, stated that disasters played a determining role in the life story of the Earth, basing this view on what befell the people the Prophet Noah. In Darwin”s model there was no space for disasters. The speculation of ‘The course of evolution’ became a dogmatic model which was taught under the name of scientific theory. Today, Cuvier”s concept of ‘disaster’ is being accepted once again in the West. Life has, now and then, been faced with sudden disasters which have affected its natural course. For 200 million years, the dinosaurs were the sovereigns of the Earth; the mammals were few. But a stone fell out of the sky and suddenly the dynasty of the dinosaurs ended. Could the same thing not happen to the false dynasty of humanity? All these possibilities of termination should lead us (and the experts) to think more carefully about our existence, life, Earth and humanity as a whole. But, unfortunately, this is not what happens, and countries which worry about meteorites only in relation to themselves have destroyed certain regions in the world with bombs, creating the effect of meteorites long before the meteorites themselves reach us; such people see nothing wrong in causing the deaths of many people. The existence of meteorites (and other cosmic phenomena) carries many divine truths. We are not alone in the time-space dimension; all these planets and their satellites, innumerable comets and asteroids move around and among us and yet they do not effect the accurate and sensitive functioning of the system; in truth, they constitute a vital part of its accuracy. They have submitted to the great Will that has created them: Do they not then look up to heaven above them how We have made it and adorned it and how it has no gaps?(Qaf 50:6) The atmosphere and the magnetosphere that surround our Earth as a token of compassion and protection serves, under Divine orders, as the shield against solar explosions that regularly take place every 11 years, against harmful cosmic radiation and particles. Otherwise, conditions that are very unfavorable to life would have been the reality, with craters pitting the surface of the Earth, just as we see on the surface of the Moon, which has no atmospheric or magnetic shields. On the other hand, the possibility of a meteorite colliding with the Earth makes us think of other things as well: How will the end of the Earth come about; through collision with a meteorite, or through more complex phenomena? This is something we cannot, and maybe do not, need to know for sure: what is more important is that the Earth will end, that the day that has been promised will come, that the day described in the Qur’an will make us shudder, and that we have to tread accordingly on this Earth. On this issue Said Nursi points to an important truth concerning faith: ‘If Earth were to explode, those servants of God with truly illuminated hearts would not be frightened—they might even consider it a marvel of the Eternally Besought”s Power. A rationalist but unbelieving philosopher might tremble at the sight of a comet, lest it should strike Earth. (This was how some Americans reacted to the recent sighting of Haley”s comet.)’ Another lesson for contemplation that the comets offers us could be the following: ‘The movements of heavenly bodies in the sky (the world”s roof), the appearance of comets and new stars while some others are extinguished, as well as solar and lunar eclipses, demonstrate that it is not stable and therefore is making its way toward a final ruin. However slow its changes are, they also show that the world is mortal and moves to its inevitable end.’ Our life has been given into our safe keeping by our Lord; and so we must try to protect it to the best of our ability. In that spirit, we can take precautions against a comet that comes toward our Earth in order to protect life; we may be able to smash it into pieces using the technology that we have. But if not today, tomorrow, or soon Doomsday will arrive; we should not forget that, just as we should not forget that rendering meteors ineffective is a gift from God Who is the true holder of knowledge and power. But will such a success lead humanity to assume a more ungrateful and arrogant position toward God, or will it end in our praising God and giving Him thanks, as did the Prophet Solomon? The last position is the following: And call not God with any other god; there is no god but He, every thing is perishable but He; His is the judgment, and to Him you shall be brought back (Qasas 28:88).

A major achievement in the computation of π was made around 250 BC. Archimedes of Syracuse (287-212 BC) had the brilliant idea to approximate π by using inscribed and circumscribed polygons that approached a circle (see the figure). The circumference of a circle of diameter 1 is π. He inscribed a polygon of n-side and computed its circumference.

This circumference is clearly less than π. Similarly, he circumscribed another polygon of n-side and computed its circumference. This time the circumference of the polygon is greater than the circumference of the circle which is π. So, he arrived at the inequality 3 < π

In the following centuries, some people used Archimedes’ technique, using polygons with more sides, and arrived at more accurate estimates for π. Ptolemy (c. 150 AD) found the value up to 4 places, Zu Chongzhi (c. 500) 6 places, al-Khwarizmi (c. 800) 4 places, al-Kashi (c. 1430) 14 places, Roomen (c. 1580) 17 places, while Van Ceulen (c. 1600) arrived at 35 places.

Unfortunately, Archimedes’ idea was the only mathematically significant approach for almost 2,000 years. The second major step in this direction came with the Renaissance. The general progress in theoretical mathematics gave a great push to the computation of π. With the aid of calculus and infinite series Gregory found the following formula: arctan(x) = 1- x/3 + x3/5 – x5/7 +… He then plugged in x=1, arriving at π/4 = 1- 1/3 + 1/5 – 1/7 +…

This formula looks very nice to begin with, but unfortunately it is not very useful for the computation of π. To get the first 4 places right, we need 10,000 terms of the series, making it very untidy. This formula was considerably improved later by others, and went on to become very useful for computation. By using trigonometry, Machin found the following formula for π: π/4 = 4arctan(1/5) – arctan(1/239).

With Gregory’s expression for arctangent, this formula became so powerful that one could arrive at 5 places of π in just 6 terms. Again, with such a formula, the only problem left is that the computation is quite tedious. In the 18th and 19th centuries, Machin, Rutherford, Shanks, and others improved the calculation of π to 700 digits.

On the other hand, amazing facts were discovered about the nature of π. In 1761, Lindemann was the first to show that π is irrational, which means that it cannot be written as the ratio of two integers, like 22/7, 353/113, etc. Then he proved that it is transcendental, or “very irrational,” i.e. it cannot be a root of any integer coefficient polynomial. In other words, it cannot be A10,A2 + A3, 3A29, etc. These facts imply that π is a very irregular number, that there is no pattern in its decimal places, and that one cannot express π in a simple algebraic way.

So, by the beginning of 20th century, we were able to compute only 700 digits of π. In the first quarter of the last century, the brilliant Indian mathematician Ramanujan accomplished the third great theoretical leap in or the computation of π, and came out with many impressive infinite series. He arrived at sound algebraic expressions which are very close to π.

In the second quarter of the last century, computers came onto the scene. With the arrival of computers, pen and paper calculations were rendered obsolete. After Ramanujan’s time, the people calculating π became programmers rather than mathematicians. In 1955, more than 3,000 digits were calculated at the Naval Ordnance Research Center in only 13 minutes, almost 500 times faster than the ENIAC only 6 years later. In 1959 an IBM 704 calculated more than 16,000 digits of π. In 1961 an IBM 7090 calculated over 100,000 digits of π in around 9 hours, in 1966 an IBM 7030 calculated 250,000 digits of π, while a year later a CDC 6600 calculated 500,000 digits and in 1973 a CDC 7600 calculated 1,000,000 digits of π in 23 hours.

However, the techniques for calculating π were still using arctangents which have a quadratic growth rate. In 1976 Eugene Salamin rediscovered a formula developed by Gauss. It was calculation intensive in Gauss’ time, but well suited for modern super computers the size of the Whitehouse and had a much lower growth rate than the arctangents formulas did. In 1982, a HITAC M-280H calculated 16 million digits of π in 30 hours, in 1988 a Hitachi S-820 calculated 201 million digits in 6 hours, while in 1989 both the 500 million and 1 billion π calculation records were broken. In 1995, 6 billion digits were calculated, in 1996, 8 billion, and finally in 1997 a Hitachi SR2201 calculated 51 billion digits of π in 29 hours. This Hitachi machine had 1,024 processors and 212 gigabytes of RAM. However, in September of 1999 a new record of 206,158,430,000 was announced. The calculation was set by Yasumasa Kanada and the University of Tokyo. The calculations took over 37 hours, with 43 hours more needed to verify them. The machine used contained 817GB of main memory and consisted of 128 Hitachi SR8000 processors.

So, we can see that this mysterious number has attracted the attention of many people for centuries; it seems set to continue to do so. It might not seem very interesting to compute billions of digits of one transcendental number, and it might even seem pointless. The real point here is not the billionth digit of the number, but the excitement and the beauty of the problem, and the challenge to human intelligence, like with so many other mathematical problems.

The fifth branch is that of love and fear, worship and imitation of the Prophet. The addressee is first Nursi’s own soul, and secondly “his friend who loves the worldly life.” In the first statement, Nursi wants to direct the love of humans to Almighty God, who deserves the utmost love.

“Love is the universe’s raison d’tre, the bond between all things, the light and life of existence. Since we are the most comprehensive fruit of existence, a love so overflowing that it can invade the universe has been included in that fruit’s heart (its seed or core). One who deserves such an infinite love can only be one with infinite perfection”;¹ this is God.

According to Nursi, human nature has been endowed with two tools: love and fear. Both of these senses inevitably will be directed to the Creator or the created. Fear of the created or blind love of the created are both dreadful calamities according to Nursi; because people become afraid of people and created things that do not show mercy toward them. As for a love of creatures, Nursi explains that many of them do not understand love and do not acknowledge us. One may love a beautiful panorama, but the panorama does not acknowledge a person; one may love the stars of night, but the stars do not acknowledge a person. Many of these beloveds leave us without ever saying goodbye, like our youth or wealth-either they leave us, or we leave them.

According to Nursi, ninety-nine percent of lovers complain about their beloved. The reason for this is that the inner heart is a mirror of God, the Self-Sufficient Who needs no one and Whom everyone else needs. And the heart can only be satisfied with His love. After mentioning this, he makes his point as follows: “So turn your fear and love toward such a One so that your fear will be a pleasant humility and your love a happiness free of humiliation.”

For Nursi, to fear God means to take refuge in his mercy. Fear is a motivator that throws a person on God’s mercy just as a child, when threatened, takes refuge in the arms of their mother. “. . . maternal care and compassion for all living beings is only a ray from His Compassion.” If fear of God is so joyful, then how does the love of God compare? There is great joyfulness in the love of God. For Nursi, even the love of creatures is joyful since it is for His sake. “Only when you can assign that love to its rightful owner can you love, for His sake and as mirrors to Him, all things without pain or trouble. Such love must not be assigned directly to existence for the sake of existence itself. Otherwise, while being a most pleasurable Divine grace, this love will become a most painful ailment.”

According to Nursi, the human soul is prone to love itself above everyone and everything else. In fact, it should not do so; the soul does not deserve such a love, as it is not the source of the beauty of the universe. “Your intense self-love is nothing but your innate love for His ‘Essence’, which you unconsciously carry in yourself and wrongly appropriate for your self. Tear apart the ‘I’ in yourself and show the ‘He’.” Underneath your ego you will find God. “All the love you divide among other beings is nothing but the love implanted in your being for Him.”

For Nursi, the whole beauty of paradise, with all varieties of beauty, is the result of such a love from Him. “However, the universe cannot compensate for even one particular manifestation of His love. Given this, listen and obey the following eternal decree, which the Eternal, Beloved One made His beloved (Prophet Muhammad) declare: If you really love God, follow me [so] that God may love you (3:31).”

Although early Islamic mystics totally rejected love for the world, Nursi found a new way of interpreting the concept of love toward the world. He says, “The world has three faces.” The first two faces of the world are admirable and desirable. The first states that the world is a place where God’s names are reflected. The world is a place where a believer can contemplate them. The world is a fair for the exhibition of God’s names. From this perspective, the world is desirable. One has to think in order to understand God in this world.

The second state of the world, according to Nursi, can be understood by the analogy that the world is a field for the afterlife. This face is also desirable, since individuals must sow in order to reap for the afterlife. Without this world, there would be no results for actions in the afterlife. There would be no place to sow, and thus no fruit. By making such distinctions, Nursi gave a new interpretation of love toward the worldly life.

The third face of the world is the one that the Sufism avoids. This face, Nursi said, is the world as a place of entertainment for those who indulge in worldly desires. This is the face which all Sufis reject. By generalization, it is understood that all parts of the world were not desirable, and thus people generally chose to leave the world. People should not connect their hearts to this world. “It is necessary to abandon the world heartily, not physically.” People have to abandon the world from the heart, not the limbs. Individuals should not abandon their studies or other aspects that are necessary in this world for this life.

One said, “I love my life, I love my youth, I love spring, I love this world, I love all beautiful things. How can I leave all of these things for God?” Nursi says, in answer to this question, “However involuntary loving is, you can direct it to a certain object. For example, by convincing yourself that something beloved is ugly, or an obstacle to or only a mirror for an object worthy of true love, this feeling of love can be diverted to the true object of love.” Nursi thus says, “I do not tell you not to love what you have enumerated, but I tell you to love them in the name of God, and in the name of the love of God. Love the beautiful fruit as a bounty from God, the Merciful and Compassionate One. When you love this, you love the Merciful and the Giver of the Bounties, al-Mun’im. This love is a collective thankfulness. To love these things is good. Love your mother and father, because they helped you when you were young. When you love them in the name of God, your love for them, in fact, is love for God. When your parents are old, you love them more; thus one loves for the sake of God. Love your children in the name of God, as they are gifts from God. Be patient if they die, and do not be without hope; you should say that they were a gift from my Lord to me, and they were His creatures. . . He took them to a better place. If I had one share in them, He had a thousand shares.” It is thus important to submit to the will of God. Nursi says, “Life is the most beautiful bounty that God has given you. When you love your life, you should know that this life is a gift from God, and you love it in the name of God. Loving your spouse is a gift, and your love should not be based on apparent beauty, because when they are old, that beauty will not last. Love should not be based on physical beauty, but on spiritual beauty, or ethical beauty. This beauty continues to the end of life. The criterion of your love for them for the sake of God is that when they lose their physical beauty, they will need you more, and you will continue in your love for them.”

In this way, the world is a reflection of God, and by loving the world, one will be led to loving God. Nursi concludes this concept with the following statement, “Love the world and what is in it, with mana-i harfi;² that is to love it not for itself, but for God, and to say how beautifully it has been created, not how beautiful it is. Do not put the love of anything in the depths of your heart, because the innermost heart is the mirror of God, and it belongs to Him.” Nursi ends with this prayer, “O Lord, bestow upon us your love, and the love of things that make us close to you.”

Nursi also speaks of ubudiyya, or worship of God. According to him, when people pray they do not pray for future rewards, because as humans we have been given our reward. “Oh my soul, worship is not the beginning of future bounties; it is the result of previous ones. Yes, we have already received our wages. Accordingly, we are asked to worship and serve.”

Nursi says that our individual existence is a bounty, and being a human is another bounty-existence is pure goodness compared to non-existence. Food is also a bounty from God prepared for the needs of our stomach. The created world is another bounty which is adored through our eyes and ears. After mentioning this, Nursi says, “Oh my soul, you have already received this wage. You are asked to fulfill worship, which is joyful and easy for the body. Despite that, you are lazy. Even if you perform some kind of worship, you ask for something more, as if the previous bounties were not enough. And you even complain, asking why your prayer has not been accepted. Yes, your duty is not to complain, but to continue praying. Almighty God gives you Paradise and eternal bliss merely as a result of His Grace and Mercy. You constantly take refuge in His Mercy and Grace. Trust in Him and listen to His divine command. ‘Say, Oh Muhammad, let them be happy for what God has given them through His Grace and Mercy. That is better than what they have collected’” (10:58).

Nursi goes on to say that the one person’s worship is not enough to repay the bounties of God. Nursi quotes a saying of the Prophet, “the intention of a believer is higher than their action,” which means that, by performing an action, an individual may have a limited amount of worship, but by making an intention one can have a limitless amount of worship. When a person says in their daily prayers “O Lord, to you alone we worship and to you alone we ask for help,” they introduce the worship of all creatures to God. This makes the amount of worship limitless and makes them the representative of all creatures speaking and presenting their worship to God. Nursi refers to this statement, saying “O Lord, we glorify you with the glorification of all your creatures.”

Nursi finishes this section by restating the importance of love for God and not for the universe. He says, “If a human is deceived by indulging in the world of multiplicity through the love of the world and is drowned, they will most certainly suffer unlimited loss. They will execute themselves collectively. If humans raise their heads and listen to the language of the Qur’an through the ears of the heart and direct themselves to unity, they then can ascend the ladder of worship, approaching the throne of perfection and then can become an eternal human.”

Nursi believes that there are two paths in front of all individuals. On one path they can use this capacity of love for transient things and, in the end, will certainly lose. On the other path, they will be aware of their importance and their unlimited capacity of love and goodness and, being a candidate of eternal bliss, they will successfully, through their trust in God, gain it.

Finally, Nursi refers to Prophet Abraham’s story, as narrated in the Qur’an. In order to make his people see the truth, when he sees a star he says: “This is my lord (according to your claims).” When the star sets (fades), he says “I do not love those that set.” When he sees the Moon, he says “This is my lord (according to your claims).” When he finds it fading, it becomes obvious that it cannot be his lord. When he sees the Sun, he says “This is my lord; this is larger.” When it sets, he says “O, my people, I am innocent of what you associate (with God).” The Qur’an speaks of his famous statement, “I do not love those that set” (6:76). Nursi says, referring to this story, “O my soul, since the truth is this, and since you are from the nation of Abraham, peace be upon him, be like Abraham and say that I do not love those that set and turn your face to the eternal Beloved.”

We all know that it is essential for life. However, probably because of its abundance and simple chemical composition, we often regard this tasteless and odorless substance as being important, but quite simple and ordinary. Scientifically, it is the exact opposite. It appears to show extremely complex and unusual behavior. It is the most studied substance on Earth. Yet, scientists are still puzzled over its strange properties. Even the best computers we have today cannot simulate all of the different properties of water.

Let us look at an example of the surprising properties of water. The strangeness of water starts with the fact that it exists on Earth. Water, being composed of two fairly light atoms (hydrogen and oxygen), should be in the gas phase at the usual temperature ranges that exist in our world. In fact, all compounds that are close to it (i.e. H2S, H2Se, and H2Te) are found mostly in the gas phase. But, compared to similar substances, it melts about 100 degrees above the expected melting point and it boils about 150 degrees above the expected boiling point (see Figure 1). The result is that it is the only material that exists naturally in all three forms (i.e. as ice, liquid, and vapor) on Earth.

In addition to the example given in the previous paragraph, water has at least 40 different surprising properties (See for example the “Forty-one anomalies of water” section in Ref 1). But, what is even more astonishing is the fact that most of these anomalous properties of water are absolutely crucial for life. Simply stated, life on Earth depends on these extraordinary aspects of water. Below we will discuss some of the anomalous properties of water and their importance for life. At the end we will briefly try to explain why water behaves so differently.

1-Water Has an Unusually High Heat Capacity

Heat capacity is a measure of the ability to store heat. Formally, it is defined as the amount of heat required to raise the unit mass of a substance by one degree of temperature. If the heat capacity of a substance is high, it will store heat well, i.e. its temperature will not rise much for a given amount of heat. Water has the highest heat capacity among common substances. This has a crucial impact on our life.

It is thanks to this fact that living organisms, which are mostly composed of water, can regulate their body temperature easily. For example, the human body needs to keep its temperature between 36.1 and 37.8 °C. This is only possible because it is composed mostly of water. Since the heat capacity of water is unusually high, even if the temperature of the environment changes greatly, the heat exchange between the body and the environment does not cause a great change in body temperature.

Another consequence is the moderation of the climate near large masses of water. The heat capacity of land is much less than that of water. This is why the temperatures of oceans tend to vary much less than that of land. The temperatures in the oceans vary between -2 0C and 35 0C. On land, temperatures may vary anywhere from -70 0C to 57 0C. Compare also the Moon, which has no water. Temperatures on the Moon range from -155 0C to 135 0C.

In addition to having a great heat capacity, water conducts heat more easily than any other liquid, except mercury. This makes the temperature quite uniform in living organisms. Also, the vertical temperature profile in oceans and lakes is essentially uniform due to this fact.

2- Water Has an Unusually High Heat of Evaporation

When a liquid evaporates, it absorbs heat from the environment. This energy is used to transform molecules into gas form. The heat of evaporation is defined as the amount of heat required to convert a unit mass of liquid into gas. Water has an unusually high heat of evaporation compared to most other common substances. It is so great that you need to supply about five times the amount of energy to evaporate water that is needed to heat it from 0 to 100 0C.

This fact is crucial for the evaporative cooling system of the human body and animals. When we sweat, the sweat absorbs heat from the body in order to evaporate. Since water has a very high heat of evaporation, effectively a large amount of heat is removed from the body through sweating. That is why when we engage in physical activity we sweat. Excess heat in the muscles is easily removed through the evaporation of sweat thanks to the high heat of the evaporation of water.

The high heat of evaporation also prevents dehydration. If it were low, water would then evaporate easily from the body and we would quickly dehydrate.

3- The Density of Water Behaves Unusually as a Function of Temperature

The density of almost all other liquids decreases with increasing temperature. Water is an exception to this. Starting from 0 °C, the density of water increases, and reaches a maximum at 4 °C, decreasing afterwards. Also most other liquids become denser when they condense, but water is an exception to this as well. The density of ice is less than the density of water, which is why ice can float on water.

Both of these exceptions turn out to be extremely important for underwater life. When the weather gets cold near a lake, first the temperature of the lake’s surface starts to decrease. As the temperature of the surface cools to around 4°C, it becomes denser and can move downwards, letting the warmer water reach the surface. Therefore, before the lake can start freezing almost all of the water in it needs to be cooled to approximately 0 °C. If there was not an anomaly at 4 °C then water would begin to freeze from the surface before the entire lake cools to 0 °C. Since water has an enormous heat capacity, the necessity for the entire lake to cool to approximately 0 °C before any freezing can occur delays the freezing considerably. It is also crucial that the density maximum in water is near freezing point, not at any other point.

When the temperature finally gets to 0 °C and the water start to freeze, it will start to freeze on the surface. Since ice is less dense than water, it will float on the surface and will not sink to the bottom. And once a surface layer of ice is formed, it will protect the rest of the lake from the environment and no further freezing will occur. There would not be any underwater life if ice formed on the bottom. It would also take forever for the ice to melt if it was formed on the bottom rather than on the surface.

The fact that water expands upon freezing is also important for the formation of soils. When the water freezes inside a rock, it can easily crack it into pieces, just like a soda placed in the freezer explodes upon freezing. Therefore, one of the most important steps of soil formation is dependent on this exceptional characteristic of water.

4- The Absorption Coefficient Anomaly in the Visible Region

Another interesting property of water lies in its absorption of light. Every

substance has a characteristic absorption spectrum that shows how much light at a particular wavelength is absorbed. If the absorption coefficient is high at a particular wavelength then the material will look opaque at that wavelength. If it is low, light at that particular wavelength will be transmitted and the material will appear transparent.

In Figure 2, the absorption coefficient of water is plotted as a function of wavelength (red line). The first thing you notice is that water has a very high absorption coefficient, except for a very narrow region around 500nm. In this small region of wavelength, the absorption coefficient is ten million times smaller than the neighboring regions. What is more interesting than this enormous drop in the absorption coefficient is that this dip happens exactly at the visible part of the spectrum. The human eye can only see wavelengths between 400-700 nm. This visible part of the spectrum is indicated by a rainbow colored strip in the graph. It is amazing that this exactly coincides with the region where water is transparent. Adding to this pleasant surprise is the fact that the amount of light emitted by the sun peaks around this dip as well.

Everything is conveniently adjusted for the habitants of this blue planet. The maximum intensity of emitted sunlight happens to be in the narrow range of the spectrum that we can see. And water on the atmosphere lets this part of the spectrum through thanks to the strange dip in the water absorption spectrum. Worried about the dangerous UV radiation from the sun? This is taken care of too. Just below the visible region, the absorption coefficient of water is ten million times higher. So water vapor in the atmosphere very effectively removes most of the dangerous UV light and shields us.

The spectrum of the light from the sun, the absorption spectra of water and the visible region of the spectrum that we can see are all physically independent phenomena. Yet, it is worth noting that each of these phenomena behaves in such a way that it seems they should have a precise knowledge of each other. If you think this is too much of a coincidence, there is even more. Water is also designed to maximize our visual pleasure. You are probably astonished by the lovely color match between the blue sky and the blue sea. Most people assume that this is because the sky is blue and the sea appears to be blue because it reflects the sky. In fact this is wrong. Water is blue since its absorption coefficient is higher in red; therefore it absorbs more red and reflects the blue part of the spectrum. This can be seen in Figure 2, in which the absorption coefficient in the red colored segment of the rainbow strip is more than 100 times greater than the blue part. The sky is blue for an entirely different reason (since it is blue light that is scattered the most by the nitrogen in the atmosphere). Again two very different, independent physical phenomena are at work here, but the result is a pleasant view for us.

Why is Water so Strange?

Most of these unusual properties of water are the result of the collective behavior of water molecules. That means that one cannot understand them just by thinking about a single H2O molecule. A single H2O molecule is a polar molecule: the two H atoms are slightly positive and the O atom is slightly negative. So when you put these molecules close to each other, the positively charged H atoms are attracted to the negatively charged O atoms of the neighboring water molecules. This is called “hydrogen bonding.” Because of this, molecules tend to order themselves rather than moving randomly, even in liquid water.

Hydrogen bonding is thought to be responsible for most of water’s strange properties. This is why, for example, water has a high boiling point and a high heat of evaporation. Extra energy needs to be supplied to break the hydrogen bonds before boiling and evaporation can occur. Another example is the high heat capacity. As water absorbs heat, it stores this as potential energy by breaking hydrogen bonds without considerably increasing its kinetic energy. This leads to a small temperature increase, therefore a high heat capacity is created for a given amount of heat.

But not all of the anomalous properties of water are that simple. Some of them are not even understood today, despite a considerable amount of current research. For example, water seems to play a crucial role in protein folding. Protein folding is the process by which each protein acquires a unique three-dimensional shape. And it can only function effectively in this particular shape. Despite millions of different possible folding configurations, a certain protein will always fold into its unique structure within milliseconds. But how can a protein always find its way to the same configuration? Water comes into play at this point. It is thought that the hydrophobic (water repelling) interactions between water and protein molecules and the hydrogen bonding interactions in water are major driving forces in protein folding. The exact details of this are still not known. Understanding them is the key for understanding many diseases and developing drugs.

In summary, water is central to our lives. It accounts for a large proportion of our bodies, we drink it, fish in it, and wash and swim in it. But we usually are unaware of how remarkable it is. Here, we have given only couple of examples of the anomalous properties of water that are also crucial for life. Scientifically, our understanding of water is far from being complete. It seems, as the research continues, that the already long list of mysterious aspects of this miraculous substance will get even longer as we learn more about it. On the philosophical side, it is interesting to note that a very simple molecule (H2O) has been selected as a means to do all of these vital, complicated, and unrelated jobs, all at the same time through its unexpected and surprising properties.

Our Creator has solved every potential problem which living things might experience by creating one optimal solution among every alternative.These perfect solutions open new horizons for men, and they also act as guides in the development of science and technology. The book titled “Engineering in Nature” details many striking examples.1

In recent research, it has been discovered how the thread of a spider can contribute to fiber-optic technology. A crucial challenge in photonic technology is to produce the tiny optic fiber that is used as a conductor for a light beam in nano-scaled optic circuits. Yushan Yan, of the University of California in Riverside, has taken an important step forward in this technology by covering the thread from a spider web with a glass-like material and then removing the thread after the material has hardened. By utilizing this technique, it is possible to produce threads that are 1/50000th the diameter of human hair and that have a radius of 2 nanometers (1 nanometer being one billionth of a meter).

Not only will this discovery be applicable in photonic technology, it will also increase the resolution in optical microscopes, or, alternatively, these threads could be turned into nanoscale test tubes in a new breed of sensors that can suck up single molecules of a particular chemical.

A research group at the University of California cut a thread 1 centimeter long from the web of the giant spider of Madagascar, the Nepila Madagascariensis, and pasted the two ends of the thread to a card. Then they repeatedly dipped this thread into tetraethyl orthoslicate solution. After this, the thread that had undergone this process was dried and heated to a temperature of 420 Celsius. The string decreased by one fifth of its original radius and the process resulted in the production of tiny tubes with a radius of one micrometer.

There are plans to make use of the web of the Stegodyphus Pasifiu-a spider which uses a thread of a radius of 10 nanometers and which is found in the Middle East and Southern Asia. This will enable scientists to use thinner fibers. After heating, a thread with a radius of 2 nanometers is attained. Until this latest finding, it was only possible to produce fibers with an interior radius of 25 nanometers.

Fiber optic researchers do not hide their enthusiasm for this new simple and cheap technology. It is expected that it will be used in the field of supra-molecular chemistry; that is the study of very miniature environments. In these environments the reaction-speeds increase and completely different reactions occur. For such experiments carbon nano-tubes are being used at the present time. The tubes made from fibers obtained from spider webs will enable scientists to create more sensitive environments. It is also thought that it will be possible to create microscopes with a higher resolution by using tinier fiber optic catheters.

Such microscopes would be used to observe events that are shorter in duration than the wavelength of light, yet at the same time, these microscopes would not cause the sample to be harmed. Electron microscopes harm the sample since the features of the technology used necessitate this. Currently, these microscopes use a scope that has been made from very thin glass tubes. These fibers are relatively thick, measuring about 100 nanometers in radius. Yet, by means of this new technology, these new microscopes can be developed and biologists will have brand new opportunities to study events that have not been visible before. Surely, it is not possible to say that the immaculate biological structure and incredibly small thread employed by the spider can be explained by simply putting its creation down to chance or by stating that it is a product of nature.

These perfect examples that can be observed in nature will lead to fundamental changes in our understanding of the universe; they will enable great leaps in terms of making our life more comfortable and, most importantly, they will be helpful in realizing how the Divine Power and Art can be present together and be in harmony.

This notion, in fact, could hold true for any work of fiction. It is an interesting question then why fiction has been used in literature for thousands of years, given that the message it indirectly contains in its text will be understood by only a small number of people. Would it not be a more rational method for the authors to simply relate the message they would like to give without adding people, events, and all those tedious details of fiction? Apart from making a philosophical point, there is yet another reason for writing fiction; the understandable urge for mortal humans to try to remember how some significant events unfolded in their lives. Through stories and poetry we are able to listen to episodes, fictional or semi-fictional, of people’s lives. However, the same question arises: If for example, the author writes to prevent the following generations from forgetting a crucial battle, then why are they not content with simply giving the actual locations and components of the army, the strategies employed, the weather, etc.? Rather, the author embellishes the story and characters through which we follow the incident. This article attempts to answer this question and concludes that as there is a psychological element in human learning, fiction has the potential of describing ideas that are not possible to relate by any other means.

First, we need to make a definition of the two different categories of knowledge: transferable and nontransferable knowledge. Transferable knowledge is the type that can be easily explained or taught to another person and which will be widely accepted if understood by the listener. For example, multiplying 2 by 2 is easy and transferable; how to use a computer is less easy, but still transferable; the theory of relativity is extremely hard, but it is still transferable. Nontransferable knowledge, on the other hand, contains elements of human cognition and feelings, and it is possible that it can never be transferred to another person fully. A mother’s love to her child is only transferable to a certain extent: However well it can be defined and in whatever detail its feelings can be explained, it can never be felt by anybody other than a mother. Knowledge of the beauty of a childhood memory can never be transferred to anyone else, not at least to the extent which the person who experienced the memory is aware of it.

Obviously, these categories are not as clear-cut as one would like to imagine; in fact, we can easily accept that there is no knowledge that is totally transferable or nontransferable. When we describe a journey that we have made, the names of the streets are transferable, but at the same time there may be quite subtle, unconscious things that these names remind us of, things that are nontransferable. The type of tree and its color are transferable, but the idea of the magnificence of the tree that elevated our belief in God is not, even though the imaging event is the same. However, all knowledge in this world can be understood as being a mixture of transferable and nontransferable elements.

It is one of the great tragedies of humanity that we carry an incredible amount of knowledge that cannot be transferred to anybody else in our lives. We can never make another person understand why we believe, why we love, how we feel. Even when we try to put these things into words, we fail miserably. If we try to explain our reasons, we even fail to explain them to ourselves. You have probably experienced such a moment: Upon trying to express the reasons for your faith, love, or feelings, you become aware that these were not the real reasons, you understand that it was not these reasons that were the cause of everything. It was an experience in time and space. You are what you are only because you have experienced your past. At this point, let us leave the layman in awe or ignorance, and let us turn to the artist.

The fiction writer or artist in general, consciously or not, has the only tool in the world that can be used to transfer nontransferable knowledge. This unique tool uses the simple idea of constructing a past for some people in the reader’s mind. Generally, a fiction work has one intended protagonist and events shape around this character. As a result, we learn a great deal of the experience that the protagonist has gone through. We have discussed above how the only real way to acquire nontransferable knowledge in the first place is by living through experiences. These experiences have molded us into what we have become. By reading fiction, by reading about the experiences of the protagonist, by relating to them, we start to feel like them. By reading the complex descriptions of how they felt and what they did, and what happened to the protagonist, we almost become them. In the end, the process has succeeded: for a certain span of time; we have felt the way the writer wanted us to. This process is bound to change our viewpoint since we have now had different experiences than before.

Another power of fiction is that it does not try to persuade you. We do not like to be persuaded and when someone tries to do so, we get defensive. Reading an ethics book that tells you to do this and that is one of the worst reading experiences. However, when you read a good work of fiction where the protagonist lives what resembles a real life and behaves well to people, in many aspects, and is liked by others, then you will feel as if you also want to be like him. I wonder if there was anybody who has not decided to be a better person after reading “The Idiot.” We learn from his letters that it was Dostoevsky’s intention to relay the above message to us when he wrote “The Idiot.” In this way, another example of nontransferable knowledge (i.e., that being good to others is a good thing) has been transferred to the reader; in fact, I cannot imagine any other way of doing this.

It is very interesting to observe how some great minds that normally do not use fiction resort to it at times when their message becomes more belief-like, more cognition-related: i.e., more nontransferable. None of Nietzsche’s books are fiction except for “Thus Spoke Zarathustra.” But again, all his other books criticize the Christian religion, posing alternative explanations for morality and interpreting Greek Philosophy. Zarathustra was a different type of book: Nietzsche knew that it had an element of belief, that it was not an analytical flow of ideas; it introduced two still controversial components of his philosophy: Eternal recurrence and the Superman. Nietzsche well knew that he would be able to transfer these ideas to his readers via fiction, as the reader would feel and live and walk with Zarathustra, and approve of his strength and relate to him, and maybe accept him.

Said Nursi, when he was writing “Ayet-ul Kubra” (The Supreme Sign) knew that if he used fiction, i.e. if he caused us to walk with the explorer in the story and find evidence of the Unity of God, then we would be able to relate to him and accept his findings. He knew that the dictation of this evidence in a didactic manner would not be as effective; belief has a psychological element. Hume, when writing “Dialogues Concerning Natural Religion” knew fiction was the best way to show the contradictions of the medieval Christian philosophical belief in God, because he knew that disbelief has a psychological element and that it can be transferred in its extent only via fiction.

Obviously, not all fiction works have a conscious intended message, but it is easy to see that every good work of fiction will have some evolving influence on the reader’s mind. In fact, leaping one step ahead, I want to suggest that abstract fiction (in particular, poetry) has an even deeper potential to transfer “more nontransferable” knowledge. The Modern and Post-Modern eras have given us fiction that speaks of our inner fears and our deepest secrets. These are ideas that even the authors cannot explain explicitly, however, by supplying a rich medium they are somehow able to remind us of these things; they are able to transfer some knowledge that is essentially non-transferable.

In summary, the fiction writer tricks us into believing that we have assumed a neutral position from where we can observe the events and people of the story. However, this position is not neutral: As we watch the story unfold, as more details become apparent, the characters become more real and the incidents become more lifelike. The teaching power of fiction is twofold: First, since we assume that our position is neutral, we do not take the defensive. Even if we read that the protagonist chants a new system of belief, even when we chant with him, we do not feel that we are being taught; it is just an event that happens in a story. Secondly, when we read about the experiences of the protagonist, and since we relate with him or her, we are also able to experience the same events. These are the experiences that make the protagonist what they are now. To an extent, depending on our prior predispositions and the power of the narrative, we have also by now lived these experiences. Again, to an extent, we have now changed in a way that would never have been achieved by listening to a lecture of ideas.

The argument above can readily be extended to other forms of art as well. The seventh art, cinema, is the one that most closely resembles literary fiction and it also incorporates components of other arts. Although there are some disadvantages concerning the narration of the thought process, these are compensated for by visual cues, and we again can learn things concerning human cognition that would otherwise not be able to be transferred.

Paintings are crystallized forms of visual cues and they can have the same influence. If I simply told you that this life is a bridge between birth and death and that there is a terrible lack of meaning, as well as there being a great ignorance on the part of most people of this vacuum, an ignorance which is maddening, you may well agree, but you would not experience the emotion I was trying to convey, and again an attempt to transfer nontransferable knowledge would fail miserably. But if you were to come across the painting known as “The Scream” by Edvard Munch (see picture), which even in the first instance seems frightening and repellent, you would wonder what this might mean, why is this man apparently screaming, of what is he afraid? Later you might notice the other people in the background, who are happy and walking on their way, apparently not noticing or maybe ignoring whatever the man in the foreground has been frightened by. Then, you might notice that the man is standing on a bridge. Maybe you would walk away from this picture without finding any meaning in it. However later, when the time is ready for you to understand, you will be able to perceive what the painter was trying to convey. Munch is trying to convey to us what we described above, but in a most delicate and cunning way. He used paint as a medium to tell this, because he knew that this is nontransferable knowledge and in order to convey this information, he had to use art.

Music might very well be the ultimate form of transferring nontransferable knowledge. Love, rage, sorrow, joy, and things that cannot be put into words can be expressed by music and can be immediately perceived, at least to some extent, by the listener. How else are we to understand the grief and wrath that Beethoven felt when he was slowly but certainly going deaf if it were not for his music? In his 3rd piano concerto, while submersed in the music, we feel the helplessness and anger of the great composer. Even if we did not know that Beethoven had composed this concert during the latter stages of his life, we would still share and feel his feelings. One high note on the flute can influence our feelings more than hundreds of words.

If we return to fiction, if we accept that this argument has some truth in it and that fiction is a way to convey nontransferable knowledge by making us live through experiences, then we should observe that the fiction which has the greatest influence on us is that which is rich in content; it is evocative. Such literature mimics human experiences as closely as possible, making us feel like we have experienced the same. In fact, we are aware of both these elements in good fiction.

Another point to note is that if this argument contains some truth, then one can consciously counteract fiction by choosing not to read the works of fiction known to have a view of the world that one does not want to accept. If we want to learn about communism, but not have our feelings on communism affected, we could read “Das Capital” with no fear. However, if we read some works of Gorky, if we see from inside the difficulties of the lives of the people and the hopes they have invested in the idea of equality and the ideal of communism, then we are almost bound to find ourselves transformed to approving of communism somewhat in the end.

Naturally, I am not pretending to explain the reason for the existence of art in this article. However, it seems that one of the reasons for art and fiction is to be able to relate things that concern human cognition, things that cannot be related or conveyed by any other means. These things cannot even be put into words. This is the power of fiction and art. Ironically though, to relay this idea to you I have used nonfiction. In fact, I know I would have been more convincing if I had made up a character who wanted to tell others about his ideas but could not achieve this via an analytical description. He might then decide to write a story and explain his experiences that led to his ideas. To his surprise, he might see that his ideas have been truly understood by his readers. If I had written such a meta-fiction, I know that the idea presented would be perceived more clearly and persuasively. I did not choose a work of fiction only because good fiction takes great time, work, and talent. This is the difficulty of art.

Animals with “Anti-Freeze”

Although it is not clear whether human beings took the idea of anti-freeze, i.e., adding a substance to water to prevent it from freezing, from animals, some animals living in cold climates have a substance in their blood that prevents them from freezing. When the skin or the operculum of fish that live in cold seas comes into contact with ice, their blood starts to freeze, and the fish soon die. The reason for this is the rapid increase of ice crystals in their blood. However, there are many fish species that live in cold areas despite such unfavorable conditions. Some species in these areas retreat to the deep water where the water is -1.8°C to prevent freezing. However, in Antarctica there are fish living in areas that are much colder than this. These fish can protect themselves against freezing in the very cold temperatures of Antarctica thanks to chemical substances in their blood that work like anti-freeze in a car. Could it be possible that this technique of anti-freeze has been codified in the genetic programming of fish not by a conscious Creator but merely by coincidence? Such an idea would be logically difficult to accept. The substance called AFGP (Antarctic Fish Gliko-Protein) found in the blood of fish in Antarctica works as a natural anti-freeze and helps fish survive in icy water without freezing. Special proteins synthesized by genes that have been codified by special programming are linked to ice crystals, and they are thus able to prevent ice crystals from forming in the body of the fish.

Researchers have discovered some of the genes that codify AFGP during their study on some species of fish that belong to the Notothenioidei suborder, which live in Antarctic water without freezing; these fish are the Notothenia coriiceps and the Dissostichus mawsoni. The genes that were discovered codify a protein in a substance that prevents them from freezing. This protein is manufactured in the pancreas, but is not broken down in the intestines. Researchers are still trying to identify the gene that codifies the AFGP. Once this gene has been comprehensively understood, the protein which the gene codifies can be produced artificially and inexpensively. In this way, a small amount of anti-freeze protein injected into the blood to prevent freezing could save many lives. However, for the time being, it seems like a far-fetched possibility that this gene can be inserted into a human genome. All the genes in our body are interrelated with one another, and therefore a new program that would change the formation of the blood, preventing it from completely freezing, might cause many adverse side-effects.

The Miracle of Salt

Many fish have substances that cause the freezing point of their blood to fall below zero. Scientists have determined that the most common of these substances are the salts found in body liquids, in particular sodium chloride. These salts account for an 85% reduction in the freezing point. It is not possible for fish, which are unaware of the physiology of the body liquid and the complex relations of the metabolism with the process of freezing, to have developed such a protection mechanism through evolution.

Fish are not the only animals with anti-freeze. From the world of insects, Cryptopygus antarcticus (the Antarctic springtail) and Achorutes nivicola (the snow flea) are creatures that can survive in very low temperatures. Many animals become motionless or die when the temperature dips below freezing. But the Antarctic springtail can easily move and jump around at these temperatures. The biological reason for this vivacity is the anti-freeze system of this insect. Some of them can even live in glaciers unharmed for a period of up to three years.

Waterproof Fur

The otter (Enhydra lutris nereis) has a different type of protection against cold. The otter has been hunted for its soft, thick, velvet-like fur, bringing it to the brink of extinction. This animal’s fur is such a fabulous protection that otters can swim for days without even getting wet. The thick fur protects the otter from the cold. Unlike many sea animals, the fat layer under the otter’s skin is very thin, and is thus not very helpful against cold. Instead, the One whose Mercy is Endless has granted them a thick fur that protects them from the cold.

Polar Bear Dens

When the dens of polar bears are examined, many fascinating aspects are discovered. If a female polar bear living in Antarctica is pregnant or has just given birth, she makes a den under the snow; this is the only way that she can survive. The cubs are usually born during the middle of winter. When they are born, they are hairless, sightless and very tiny. These totally vulnerable and very needy babies are born in the middle of winter and they need proper dens in order to survive. A typical den consists of a two-meter hole and a round cave half a meter in diameter. It is only about half a meter high. However, this is no ordinary shelter constructed by a simple procedure. In a place where everywhere is covered by snow and ice, this den is dug very carefully under the snow drifts, and every detail necessary for the lives of the cubs is ensured. These dens usually consist of more than one room. Despite the fact that polar bears lack knowledge of thermo-dynamics, they dig out a smaller den above the entrance, ensuring that the warm air in these rooms cannot escape. Throughout winter, snow accumulates at the entrance and on top of the den. The polar bear leaves only a small, narrow channel through this snow drift to allow the air in. The thickness of the roof constructed by the mother bear is somewhere between 75 centimeters to two meters. This roof works as a good insulator, keeping the existing heat inside.

A researcher from Oslo University, Paul Watts, placed a gadget on the ceiling of one of these dens to carefully measure the heat. His findings were surprising: while the temperature outside fell below –30 degrees, the temperature inside never fell below 2 or 3 degrees. The scientists were also amazed to discover that the mother bear constructs her den like an expert physicist, building her nest with perfect insulation. In this warm and protective setting the mother bear does not die of cold because the fat reserves in her body are sufficient for her hibernation period. However, the period of hibernation is an even more interesting issue: the metabolic rate of the mother bear slows down to save energy, thus enabling the cubs to be better nourished. Thanks to these characteristics, granted by the One whose Mercy is Endless, the fat stored in the bodies of polar bears is turned into protein over a hibernation period of seven months, feeding the cubs. This is how the polar bear survives without eating any food for such a long time. Its heart rate decelerates from 70 beats per minute to 8, and the metabolism slows down in accordance with this. As the bear does not eat any food, it does not need to defecate or urinate.

Parenthood in a White World

It seems as if penguins (Aptenodytes forsteri) thumb their noses at the freezing cold. The mothers return back to cold seas shortly after laying eggs in order to feed. The mating pairs do not build nests, because there is nothing around them except snow and ice. Yet, they cannot leave their eggs on the ice, for the egg would be immediately frozen. So, while the mother is hunting for food, the father penguin takes care of the chicks over a period of three months. The fathers gather around in a group to carry, initially, the eggs, and then the chicks, holding them on their feet in order to protect them from freezing. The feet of penguins are covered with feathers, and are 80 °C warmer than the outside temperature, thus keeping the egg from freezing. The penguins form a circle with their backs facing out, and the chicks on the inside. Those fathers that happen to be located at the outer most part of the circle change places from time to time with the other penguins to protect themselves from freezing. This is necessary, because the temperature is around -50 °C.

Are such animals as we have discussed here capable of learning and thinking? Or are these abilities that are peculiar only to humans? Differentiating humans from animals along strict lines, Descartes (1596-1650), who said “cogito, ergo sum: I think, therefore, I am,” went so far as to claim that animals do not feel, let alone have an ability to think. Some biologist today argue that animals might not have the ability to think as we understand it, but they can still behave in some logical ways that are peculiar to them, and they can learn. Nevertheless, we cannot give animals credit for comprehending the need for anti-freeze in their blood, the protective characteristics of salt against freezing, how they should make their dens, or form circles to protect themselves against the cold. Rather, we could say that all these are manifestations of the most beautiful names of our Lord. One of the meanings of the 16th verse of the Surat al-Anbiya, It was not for nothing that We created the Heavens and the Earth and all that is between, is that we are to understand that there is a Divine Wisdom and Insight in the creation of each and every one of the creatures of the universe.

“The things that I fear most for my people are being overweight, sleeping too much, laziness and a lack of deep faith.” 1
Prophet Muhammad (peace and blessings be upon him)

Effective time management occurs only when we force ourselves to perform important activities within a plan so that we can reach our goals. Goal setting and planning our activities are important steps in this. But if we fail to engage in these activities and to finish them, then we end up with an unfulfilled plan on our hands. Our mind-body is the only vehicle through which we can accomplish our goals in life. Our eating habits, including the type and amount of food we eat, affect our mind-body in many ways, such as our energy and stress level and our sleep patterns. Hence, it is crucial to examine the impact of eating habits on our mind-body. It is notable that time-management literature’s vast majority pays little or no attention to this aspect of mind-body control. In this article we will consider three factors in this respect: The impact of the amount of food we eat, the timing of meals, and the nature of our food.

“Limit eating, limit sleeping, limit talking. This is the path to the spiritual life.” – Sufi proverb

The Impact of How Much We Eat and Drink

There is little mention of eating habits in time-management literature. However, our eating habits affect our management of time in many different ways. Let us first consider the times of our day that are immediately affected by our eating and drinking habits:

1. Food preparation or waiting time,

2. Eating/drinking time,

3. Digestion and mental recovery time after the meal,

4. The time spent in the lavatory, and finally

5. The extra sleep we may need after a heavy meal.

It is easy to see that the impact of each of these factors is proportional to the size of the meal. The more food we prepare or ask for, the longer the preparation/waiting time will be. More food also takes longer to eat. The next stage, which is very important, is the time needed for digestion and mental recovery after the meal. Depending on the type and amount of food we intake, the digestion time can range from one hour up to three or four hours. When the amount of food is great, our digestive system competes with our brain for the limited amount of sugar in our body. This may prevent our brain from functioning at its peak. Consequently, we may experience a lack of focus, a lack of energy, or we may feel sleepy. Most people try to compensate for such feelings by drinking caffeinated beverages, which have their own disadvantages.

The time we spend in the lavatory is also proportional to the amount of food we eat. When we eat more, our visits are more frequent and more time is spent there. Eating foods that are rich in fiber is also another cause of frequent visits to the lavatory. But a diet deficient in fiber is not healthy, so the way to cut back on time spent there is not to cut back on fiber-rich foods, but rather to cut back on the amount of food we eat.

Finally, the type and the amount of food we eat affect our sleep patterns. First, when we eat more, we need to sleep longer. It is no coincidence that people who overeat also tend to oversleep. But the impact is not limited to sleeping time alone. Stimulating foods or drinks near bedtime disturb our sleep patterns and cause us to benefit less from our sleep. This, in turn, results in our efficiency being affected the following morning.

When we consider all these factors, we begin to realize how overeating makes self-management difficult and we can understand the wisdom behind the prophetic saying “No human being has ever filled a container that is worse than his stomach. . .”2

The Impact of What We Eat and Drink

In addition to the amount of food, the type of food we eat is also important. Certain types of food may energize our brain, while certain others make it sluggish.3 In order to increase one’s energy levels, nutritionists recommend a balanced diet that is devoid of harmful substances. An important property of the food we eat is what is known as the “glycemic index.”4

The Glycemic Index of Foods

Since sugar is the substance that gives us energy, many people are under the false assumption that the more sugar we consume, the more energetic we feel. This view, however, fails to account for the compensatory balance in our body. When we consume large amounts of sugar, either in the form of pure sugar, or via foods that are rich in sugar, the amount of sugar in our blood stream increases. Our body responds to this situation by secreting insulin into the blood stream, reducing the amount of sugar. If the increase in the sugar level is very steep, than the body reacts strongly to reduce it and causes the sugar level to fall to a very low level. This is why we feel sluggish for some time after consuming sugar-rich foods.

In order to avoid the down-time of insulin compensation, nutritionists recommend that we avoid foods that are high in simple sugars and which have a high glycemic index in carbohydrates. The “glycemic index” measures how much the levels of circulating blood sugar increase within a few hours after eating a particular food. Examples of foods and drinks with lots of simple sugars include cookies, cakes and other baked goods, candy bars, sodas, and fruit juices. These foods and drinks include large amounts of simple sugars, such as glucose or fructose. Initially, they give us a quick energy boost. In the longer term, however, the body’s monitoring system increases the levels of insulin in the blood and hence we experience a quick decline shortly after this boost. The brain can only use glucose for energy. When the glucose level drops in the blood, the brain cannot perform at its peak. We may end up feeling even more drained than before we ate or drank. In order to maximize brainpower and mental focus, we need to minimize fluctuations of blood sugar by selecting foods with lower glycemic index numbers. These will break down more slowly and release glucose gradually into your bloodstream. The insulin response will also be more gradual and we will not suffer a mental down time. The following table shows the glycemic indices of certain foods:

The Interaction of Food with Hormones

Our food intake also influences the release of important hormones, such as serotonin, melatonin, and dopamine. Serotonin gives us feelings of well-being, personal security, and relaxation. A shortage of serotonin may leave us feeling very tired, needing excessive sleep, with feelings of low self-esteem, causing negative thinking, and maybe even difficulty in concentrating. However, excessive levels of serotonin are also harmful.

Melatonin is a hormone that is believed to be involved in the regulation of sleep. Melatonin secretion is significantly higher at night, although some is produced during the day. The pineal gland, where melatonin is produced, functions as a biological clock by increasing its output of melatonin at night by more than ten times. This increase in secretion begins around sunset and reaches a peak at around 2 a.m. After this peak, it falls to a low level by the time of sunrise. High levels of melatonin can induce drowsiness.

Dopamine stimulates alertness and awareness. However, excess levels can cause an increased heart rate, muscular tension, and disrupt sleep patterns, as well as resulting in shortened attention span and excessive self-confidence. Excess levels of dopamine have been associated with ADHD (Attention Deficit Hyperactivity Disorder) and risk-taking behavior.

Serotonin, melatonin, and dopamine are constantly being produced in our bodies. But we can increase or decrease their levels by changing our habits. Our eating habits, spiritual well-being, and activity all affect the hormone chemistry in our bloodstream and in our brain. These in turn affect our moods and tendencies.5 This is one reason why we can feel differently about the same task at different times of the day. Carbohydrates, for instance, can alter the level of serotonin in our brains and bring on feelings of calm and relaxation. While these effects can be desirable at night, they are certainly not what we want when we need to increase our energy level. Certain proteins can help increase levels of dopamine. Thus, we may prefer a menu rich in proteins rather than carbohydrates before a mentally demanding task. In the evening, some hours before we go to bed, we may want to avoid stimulating foods as they may interfere with our sleep. If our sleep is affected, we may wake up drowsy and drained.

The Impact of Caffeinated Drinks

Although caffeine can induce a short-term stimulation to our body and mind, it will also cause a negative rebound effect. Furthermore, in the long run the brain adapts to caffeine intake and may not be able to function at its peak when we do not supply it with the accustomed levels of caffeine. This is an unhealthy dependency. If you are already used to taking caffeine regularly to boost your energy, work on slowly eliminating it from your diet. Decaffeinated coffee and tea may help get rid of the addiction while maintaining a placebo effect. One advice for a quick lunch that will not deplete your energy, but rather increase it, is to eat pure protein. Tyrosine, one of the amino acids in protein, is well known for its ability to increase levels of alertness and energy levels. Foods such as broiled fish, sliced poultry, boiled eggs, or tuna are good sources of tyrosine.

Additional advice from nutritionists to prevent fatigue includes getting enough iron, taking advantage of herbs, and preferring natural foods over artificial ones.

Conclusion

In this article we have addressed a commonly overlooked aspect of time management: The impact of our eating habits on self-control and productivity. In addition to its negative consequences on our health, eating too much also affects how we make use of our time. Overeating is one of the primary causes for excessive sleep, fatigue, and loss of mental energy. Foods rich in simple sugars in particular are responsible for dips in performance shortly after consumption. The type of food we eat and the timing of our meals also impact our mind-body. Various hormones that affect our performance are affected by our nutrition pattern. In the prophetic saying we quoted above, Prophet Muhammad, peace and blessings be upon him, links excessive sleep, laziness, and a lack of reflection with overeating. It is remarkable that such sound medical advice came from a person who lived in the 7th century. The recommendation in this prophetic tradition is fully applicable today: Moderate eating is the key to self-control and effective time management.

His dreams drove him crazy; a crab had pierced its claws into his brain. He forsook his prayers and devotions, and neither ate nor slept.

Unable to rest tranquilly in one place, he wandered to a meadow, his head confused with the charms of his vain fancies. An old man was kneading mud upon a grave in order to make bricks. Absorbed in thought, the old man said:

“O foolish soul! Hearken to my counsel. Why have you attached your mind to that gold brick when one day they will make bricks from your dust? The mouth of a covetous man is so wide open that it can be closed again by one morsel. Take, O base man, your hand off that brick, for you cannot dam the river of your avarice with it.

“So negligent have you been in the thought of gain and riches that the stock of your life has become trampled underfoot. The dust of desire has blinded the eyes of your reason-the wind of desire has destroyed the harvest of your life.”

“Wipe negligence from your eyes, for will you not be buried under the dust tomorrow?

“Your life is a bird, and its name is Breath. When the bird has flown from its cage it does not return to captivity.

“Be watchful, for the world lasts but a moment, and a moment spent in wisdom is better than an age in folly.

“Why do we fix our minds upon this caravanserai? Our friends have departed and we are on the road. After us, the same flowers will bloom in the garden, and the same friends will still be sitting.

“When you arrive in Shiraz,² do you not clean from yourself the dust of the road?

“Soon, O you are polluted with the dust of sin, you will journey to a strange city. Weep, and wash away the impurities with your tears.”

According to the Islamic perspective, there are three types of information sources:

Knowledge obtained through the five senses or relating to these senses. These include, seeing, hearing, smelling, tasting, and touching. For example, something that is seen is there, and something that is felt through touching exists.

According to the trend which accepts only this source of information, anything beyond the perception of these senses cannot be a subject of knowledge. This positivist trend has lost its influence over recent decades; however it was widely popular at the beginning of the twentieth century.

The second source of information is the “mind.” When the “mind” is mentioned, an unbiased decision-making entity, capable of evaluating matter within its pure form, and competent of making an objective decision is implied. The importance of a non-degenerate, unbiased, non-oppressed, functional mind is undeniable for information. In the modern world, rationalism is the representative of this tendency. Since its emergence, Rationalism has always advocated the “mind” as the only source of information. However, even rationalism is not sufficient to achieve true knowledge.

Another source of information is “authentic narration.” Authentic narration should be understood in two ways. Firstly, it is knowledge that has been transmitted by a number of different people and accepted as true. For example, a narration about a continent or a country to which one has never been is an authentic narration. To illustrate further, for a person who has never visited the continents of Australia or America, any accurate information, or first-hand information, obtained is of this type. It is possible that we may not have visited or seen these places, however millions of people live on these continents and hundreds of thousands of people visit these continents every year. The information gathered from these people is so powerful and trustworthy that anyone who has not seen these places cannot doubt their existence.

Secondly, authentic narration can also be considered to be that of “Divine Revelation.” In other words, this would consist of the Divine Books revealed to the messengers by God Almighty, where the revelations were brought by the Angel Gabriel (pbuh).

Human beings are not capable of seeing or hearing everything that exists, and thus they are not capable of knowing everything that exists. The mind cannot comprehend everything that exists. There are so many things that exist but which are not sensed through our senses or understood by our minds, or even, if the mind does understand them, can never be sensed or reached. Hence, the human being can only learn these facts through the teachings of a Divine Being whose knowledge, power, and will surround everything. We can only learn the things He knows to the extent that He teaches us in His Divine Books; in this way we become knowledgeable of those matters.

In order to discover the wonders of the universe and to achieve a better and more accurate knowledge with our five senses and mind, we must make evaluations under the light and wisdom of Divine revelations. Only when manipulated to work under these principles will science be able to accomplish its task of producing the fruit that it should.

Otherwise, partial falsification or incorrect interpretations of the Divine Books is inevitable. Moreover, if only the senses and experience will be the basis of information, then one will be forced to say “I do not believe in anything other than what I see, hear…” This is tantamount to rebelling against everything that the mind puts forward. In fact, if only sensory information is taken as the basis of knowledge, then people will be forced to search for compatibility between their deduced knowledge and the universe that is Created by God Almighty. In such a system, whatever facts agreed with their theorems would be true, anything else would be false. However, as God says in the Qur’an: “We did not take the human beings as witnesses to the creation of the Heavens and the Earth” (18:51). When the Divine revelation is not taken into consideration, every explanation is no more than a theorem or a guess.

Unfortunately, because only the first two types of sources were accepted, many Divine Revelations were rejected. With the progress of science, their validity has once again been proved. For example, the stages of an embryo in the mother’s womb have been well defined. When Omer Khayyam, who was an extreme rationalist, was asked about these verses, his response was to comment against the Qur’anic truth by commenting that the verses were not meant literally. Some other scholars thought that a person can only have faith in the “resurrection,” as it cannot be understood by the mind; however, Said Nursi has explained it with a simple analogy. The resurrection is like the spring that follows the winter. We do not have any actual sensory knowledge that this will happen, we know from observation and reasoning that the spring will come. Since some people only trust in the two types of sources, they had to twist what they read in the Divine Book, even the fundamentals of faith . For example, through the influence of philosophy, Farabi and Ibn-i Rusd, even though they were geniuses of their time, considered the Divine Revelations and the prophethood as being man-made concepts.

Some thought that philosophers were higher in status than the Messengers of God. The All-Knowing God was aware of how the Messengers would perform their duty of conveying the message; i.e. with an extraordinarily superior performance. This is why they were given the prophethood in advance; yet philosophers could not see this fine nuance. Moreover, it can be concluded that philosophers are only translating what Aristotle had earlier said to suit their time.

If the Islamic World is considered as a whole, it can be seen that not everybody fell into these traps. Zehravi, Ali Kuscu, Jalaleddin Devvani, Gelenbevi and many others, did not fall into these traps; they were very religious, and they were very influential in their times. People like Molla Husrev and Al-Harazmi, with their work in sciences that led their fields of study for many centuries, even in the West, were still able to maintain their faith without experiencing any conflict and lived for the most part as religious, pious people.

In conclusion, it would be proper to say that all sources of information must be handled together if one is to achieve an end result. Discriminating between these information sources and taking them discretely will open up pitfalls for humanity. The same pitfalls will continue to open if the same mistakes are repeated. Humanity will have to say “True” to those things it claimed as “False” the day before. However, using the Divine Revelations as the foundations of knowledge, and surrounding and framing them with the information attained from the senses and mind is the only path that will lead us in a true direction.
