“It is He who created the night and the day, and the sun and the moon; all (the celestial bodies) swim along, each in its orbit with its own motion.”  (Quran 21:33)

Almost everyone – depending on his or her age, experience, and education level – is aware of certain facts about nature. We know that the Sun rises in the east and sets in the west; water boils at 100 centigrade; humans have five basic senses; birds can find their way back after migrating thousands of miles; and many more. Likewise, laws of thermodynamics, laws of motion, universal law of gravitation, and laws of planetary motion are among the many tools scientists use to explain how nature and the universe work. In the same context, whether or not we are conscious of it, there is this ubiquitous fact of “revolving, rotating, and circling” in the universe in relation to science, religion, and culture. From the Milky Way, sun, planets, and moons to human eyes, circling is everywhere in the universe. Also, it’s imprinted everywhere in the natural world. Giving examples from scientific, spiritual, and social life, this article aims to inquire the “revolving, rotating, and circling” phenomenon to see if it has any implications for humanity.

Rotation of planets

Earth is one of the eight planets in our solar system, all of which orbit the sun, a giant burning star. We know from astronomy that the sun can fit more than one million Earths inside it. Throughout human history, stargazers have realized that all these planets move in a systematic way. The planets orbit due to the immense gravitational pull generated by the sun. Even though the rate may change, each planet rotates around the sun and on its own axis, an imaginary line running through the center of every planet. Also, there are more than one hundred terrestrial, gas, and dwarf moons that revolve around the planets. Every planet, except Mercury and Venus has at least one moon. For example, the Earth has only one Moon (Luna) which orbits around Earth every 29 days; on the other hand, Jupiter has at least 67 moons such as Ganymede, Callisto, and Europa in orbit around it. In addition, our solar system is swarming with different types of bodies (e.g. comets, meteors, asteroids, and space dust) that rotate around the sun along with Earth. Furthermore, it is believed that the Sun is one of about 200 billion stars (maybe more) just in our galaxy, the Milky Way. Galaxies move and gravitationally pull each other, and they do so while rotating around a center. That is, nothing is truly at rest. (1)

Orbiting an atom

In the 1920s, scientists of quantum mechanics discovered that an atom acts like a small solar system. While planets circle elliptically around the sun, electrons rotate around the atom’s nucleus in diffuse, cloud-like waves; these are known as orbitals since they tell us only the probability of detecting the electron at various places within the atom (Choe 2004). These orbitals can blend together to constitute a clump-like “wave packet” that includes the electrons and does rotate around the nucleus. It looks like this quantum phenomenon seems to support rotation in the universe. (2)

The circulation of blood

Doubtless, the heart is one of the most vital and fascinating organs in the human body. It incessantly pumps fresh blood with necessary nutrients throughout the body so that we can survive. Even though it is as big as your fist, it works like a powerhouse by expanding and contracting 100,000 times each day, pumping approximately five quarts of blood per minute, around 2,000 gallons every day. While the heart beats, it pumps blood through blood vessels in the circulatory system to every area of the human body, which takes about 20 seconds to circulate all over the vascular system. It is reported that the blood travels approximately 12,000 miles per day – nearly half the distance of the Equator (24,902 miles). Blood circulation is vital and fundamental to human life: it not only transfers fresh oxygen and nutrients to organs, but also carries away waste such as carbon dioxide from the organs, which is necessary to maintain a healthy life. (3, 4)

Five stages in the human life cycle

Similar to the cycle of four seasons (spring, summer, fall, and winter) in a year, the human life cycle has five or six different stages (Birth, infancy, childhood, adolescence, and adulthood). Human life begins as a single tiny cell, not bigger than a mustard seed, in a mother’s womb. After nine months, circa 40 weeks of pregnancy, the mother gives birth to a newborn. During the first year of infancy, the baby is entirely dependent on the parents’ care, but babies develop very quickly to independency. Childhood includes a period from age 4 to 13, when children learn to eat with utensils, dress and undress without assistance, make friends, play with other kids, and other things. Adolescence is the when a child develops into an adult, when teenagers undergo a rapid transformation of their bodies known as puberty. After the age 20, the human body reaches peak fitness and fertility by stopping development and growth. As we age in adulthood, it takes our body a longer time to repair itself and we become less efficient in many skills. (5)

Circling and prayer

It looks like that this one important pillar of Islam reminds us of the spinning motion in the universe, atoms, the circulatory system, and the life cycle. According to Islamic scholars, millions of pilgrims circulating the Holy Ka’ba in Mecca represents the deep reverence in Oneness of Almighty God. It is believed that these seven compulsory circumambulations of the Ka’ba (the most sacred site in Islam) include individual and social meanings like solidarity and maintaining unity. One explanation as to why Muslims circle the Holy Ka’ba seven times, is the Qur’anic verse that describes the sky above as of seven layers:

“The seven heavens and the earth and whatever is in them exalt Him. And there is not a thing except that it exalts [God] by His praise, but you do not understand their [way of] exalting. Indeed, He is ever Forbearing and Forgiving” (Al-Isra17:44).

It is known in Islam that the spiritual part of the human being includes seven different souls known as nafs. Therefore, every circumambulation of the Holy Ka’ba is meant to move from one spiritual level to the next in order to reach and complete the final expectation to turn our self (nafs) from meat and bone into a more delicate, sensitive, and loving form of soul, one even superior to the Angels. This act of circling the House of God, the Holy Ka’ba, shows how man is sincerely, spiritually, and lovingly attached to the divine.

Conclusion

The planets circle the sun, electrons circle the nucleus in an atom, blood circles the human body, pilgrims circumambulate Holy Ka’ba, and seasons and life cycles circle. There are many more examples of circling in the universe. Even though we cannot see all of them with the naked eye, the entire cosmos, ranging from invisible particles to the moons, planets, stars, and galaxies, are in rotation. Remember that all these rotations happen in accordance with the laws that govern the nature. There is no free choice in any of it.

People are members of this infinite universe, and, unlike planets, electrons, flowers, and cells, they can reason and decide, since we are blessed with free will. As Muslims circumambulate the House of God, this pulling motion between the Ka’ba and pilgrims escalates divine love by changing spiritual dimensions in a way similar to moths flying and circling a light source. Without doubt, a visit to the House of God is an obligatory and praised pillar of Islam, but I believe that the Merciful God wants us also to circle many other divine values and social qualities to deserve His love, mercy, and grace. As long as we circumambulate these highly valued vital qualities such as prayer, selflessness, charity, affection, forgiveness, respect, love, truth, compassion, modesty, patience, and all other good qualities, they will pull us closer both to each other and to Almighty God. Ignoring circling these divine and social qualities would be as if Earth left its orbit.

In order to find answers to these questions, let’s consider ourselves sitting at home after a long, tiring day. Are we aware that we are moving very fast even at a moment when we seem to be resting? When we travel by bus, we are motionless from the standpoint of a sitting passenger, yet have a velocity compared to an outsider standing on the sidewalk. The trees lining the road seem to be going backwards, but they are fixed to the ground with no speed. Therefore, velocity is relative and we in fact move at different speeds while sitting at home depending on the objects of reference. We have a zero velocity relative to our guests sitting with us on the couch, but have various speeds compared to the center of Earth, the moon, the sun and the center of the Milky Way galaxy. Not only us, but all existence in the universe has a movement, or oscillation. This movement is usually in the form of a revolution for objects of important mass and as a vibration for particles with smaller masses.

The shining celestial bodies of the cosmos rotate around themselves like whirling dervishes. They revolve around other heavenly bodies or around their common center of gravities, such as pilgrims revolving around Ka’ba in Mecca. The gravitational force set in the universe pulls all objects towards each other. This gravitational force indeed pulls all masses together; however, it is counterbalanced by the motion of revolution given to grand heavenly bodies. As a matter of fact, everything is moving: a solar system with its planets, moons, and comets; the Milky Way galaxy, along with billions of stars, nebulas, galaxies, interstellar dust, gas clouds, and other celestial objects… all are moving in a giant rotating motion like a carousel. In this article, you are going to find some of the scientific findings of our revolving planet, the sun, and the universe, and how some verses in the Qur’an sound miraculously relevant to them.

The Earth’s motion

First of all, we have a velocity stemming from the Earth’s rotation. People living on the equator travel approximately a thousand miles per hour in reference to the center of the globe due to this rotation. While people on the poles never gain any distance over 24 hours, people on the equator travel nearly 23,800 miles! Inside a plane, because we move at the same rate as the plane, we cannot feel its speed. In a similar way, since we move at the same rate as Earth, we cannot feel the globe’s movement.

There are many benefits associated with the Earth’s rotation. The delineation of day and night, atmospheric jet streams, oceanic currents, and similar events rise from the rotation of Earth around its axis. For instance, it causes the warm water currents of the Gulf Stream to reach England, generating a warm and rainy climate.

There are verses in the Qur’an that point to the globular shape of the Earth and its rotation around its axis and revolution around the sun:

“He has created the heavens and the Earth with truth. He wraps the night around the day, and He wraps the day around the night. And He has made the sun and the moon subservient (to His command), each running its course for a term appointed (by Him). Be aware! He is the All-Glorious with irresistible might, the All-Forgiving.” (Az-Zumar 5)

Yet another verse furthers this point:

“It is He Who has created the night and the day and the sun and the moon. Every one (of such celestial bodies) floats in its orbit.” (Al-Anbiya 33)

The verb “wrap” is usually used for round objects, and the perpetual arrival of day and night are only possible with a circular planet. The Earth’s rotation leads to different days, on the micro level, and different seasons, on the macro level. The Qur’an concisely summarizes all these physical events with the simple phrase, “wrap the night around the day.”

The Earth’s primary motion is around the sun. We are roughly 93 million miles away from the sun and we make this orbit, which is nearly 584 million miles, every 365 days. According to the center of the sun, our average velocity on this orbit is approximately 66 thousand miles per hour.
In addition, other planets travel around the sun via different orbits and speeds, each moving on a separate plane. For a moment, it is significant to visualize the sun, which is more than a million times larger than Earth, with its planets and other viscera revolving around it via no visible bond between them.

The movement of the sun

As stated earlier, when we travel on a bus, we observe the trees and buildings near the road going backwards even though we are the ones moving. In a similar way, we see the sun as revolving around us, though in fact the Earth is the one moving. In the Qur’an, the chapter of Al-Anbiya, the verse reading, “each running its course,” is about the creation of the sun and moon, clearly pointing to their movements. Unfortunately, the verse that reads, “A(nother) clear sign for them; And the sun runs the course appointed for it for a term to its resting-place, for the stability of it(s system)…” (Ya Sin 38) was misunderstood as the sun revolving around the Earth. However, we know today that our sun is one of a couple hundred billion stars in the Milky Way galaxy. As such, it both rotates around itself and revolves around the center of the Milky Way galaxy, and confirms the miraculous declaration of the truth in the verse.

In addition, the sun also has a secondary movement inside the local star cluster towards a certain direction. We can explain this with an example: the atmosphere is in motion along with the Earth. Each particle and particle set that makes up the atmosphere not only moves right and left, but also has a total revolution around the Earth. The sun behaves in a similar way within the star cluster and around the center of the Milky Way.

How are we going to define the velocity of the sun? We can determine the sun’s speed by referencing a constant point depending on the average velocity of stars in the section of the galaxy that we inhabit. The sun, according to a local constant point, travels towards the shiny Vega star in the Lyra constellation with an average speed of 43 thousand miles per hour.

Apart from their individual movements, the stars in our galaxy also revolve around the galactic center. The velocity of this movement depends on the star’s mass and its distance to the galaxy’s center. The sun completes one loop inside the Milky Way galaxy every 225 million years. It has completed a total of 20 tours around the galaxy’s center since the Earth’s creation. Our Earth, which moves along with the Sun, travels around the galaxy’s center at nearly 492 thousand miles per hour.

The motion of the Milky Way galaxy

Our galaxy is one of the billions of galaxies in known space. Galaxies are the biggest known structures. The universe expands and galaxies move away from each other, conforming to the meaning of the verse, “And the heaven, We have constructed it mightily; and it is surely We Who have vast power, and keep expanding it” (Adh-Dhariyat 47). Our galaxy, along with nearby galaxies, is pulled towards the Leo and Virgo constellations. The cause of this attraction is not understood yet.

Since all galaxies are moving, how can we determine the velocity of the Milky Way galaxy? As is known, the entire universe is filled with cosmic radiation as a remnant of the Big Bang. When this radiation is taken as a reference, the Milky Way travels at around 1.3 million miles per hour.

At the moment, when we think we are sitting in place, we are actually moving around the center of the Earth, sun, our local star cluster, the center of the Milky Way galaxy, and also moving away from other galaxies. We have velocity in relation to all of these movements. The revolution of the universe is also a fact verified by the Divine word: “I swear by the heaven ever-revolving” (At-Tariq 11).

As planets have been moving like whirling dervishes around the sun for millions of years, the Milky Way and billions of galaxies in the universe constantly keep turning in space, whose boundaries we are unable to define, in a realm of ether. As the world completes rotating around its own axis in 24 hours, it orbits around the sun with a speed of 30 km/hr and it does not even make a second’s delay in completing its yearly tour. A crowded family formed by the other nearby worlds and their satellites are travelling toward the Vega system with a speed of 220 km/second. Thanks to this rhythmic order, the orbits of planets and their positions at a given date, the times for lunar and solar eclipses, and changes with the length of days and nights, can be predicted years in advance, or calculated for historical times. The repetitive nature of these movements and continuity of the present order, for millions of years, show that everything depends on a certain plan and law, and that nothing acts on its own. There is no place for coincidence when things happen within a frame of laws, where order and rhythm exist.

The continuity of existence depends on the repetition of existing motions within a certain period – namely, on rhythmical motion. The cessation of motion in the cosmos would mean the non-existence of rhythm. It is not possible to talk about rhythm without motion and activity. This movement in existence must have a meaning and purpose. It is exceedingly difficult to explain, with physical laws, why existence came to be and the purpose in this motion. In addition, why this motion began and how long it will last, cannot solely be explained with physical laws. However, there is great meaning in this harmonious turning; an unbroken bond in existence, and a unity. Everything uses a silent language to give a meaningful message to insightful hearts. Then, how is this message supposed to be read and understood?

As we understand from holy scriptures, existence is made subservient to humanity. Existence stands as a means for human comprehension of the meaning within. A person who can view existence with eyes of wisdom and manages to hear creation’s silent melody becomes enraptured with this rhythm and feels like a whirling dervish awed by the Divine.

Rhythm in nature

There exists a balance in nature and a meaningful bond between beings. As everything runs in harmony, beings both help and compensate for one another. The sun, the earth’s source of energy and light, and essential for the continuity of life, is made dependent on a certain order with its rhythmical motion; the world and other planets move in accordance with this main rhythm. Day and night happen by the earth’s spinning around its axis, which is another rhythmical and constant occurrence. An absence of rhythm causes uncertainty and the situation is defined as chaos. If the future is completely uncertain, it gives way to utter chaos and life on earth cannot continue.

The holistic and integrated nature of beings is reflected in human biology, as it is in all living beings. Humans can always perceive, in daily life, that the motions in the universe are in a rhythmical order. As a person comes to this world connected with these rhythms; one can feel their effect in every stage of life and in one’s own body. The circular motion that occurs with the periodical repetition of minutes, hours, days, seasons, and years influences us. The inner rhythm we call our “biorhythm” is adjusted in accordance with the order outside, and there is a 24-hour periodical rhythm in daily life. Every individual has an innately given, peculiar, and distinctive bio rhythm special to the person’s biological and spiritual structure. As in human beings, a periodical rhythm is observable in many living things’ metabolism, heartbeat, and bodily functions, like respiration and sleep; this is known as the circadian rhythm. If the rhythms of living beings are upset, their biological balance is also upset, a situation which can sometimes cause death.

There is no place for coincidence in the universe; everything runs in a regular order established by the One of infinite wisdom. What brings order to life is the existence of rhythmical motion and the continuity of this order, which gives people a sense of security and makes life easier. One can make daily, weekly, monthly, and yearly plans. For example, the fact that the sun’s motion depends on certain physical laws that can be defined with mathematical formulas, and that we see it rising at a certain hour from the same direction every day, gives a sense of comfort to our mind and feelings. Most people do not even worry whether the sun will rise the next day. A person with sound reason does not fall into contradictions while observing occurrences and looks to future with trust. Thanks to periodical occurrences, a person finds a beauty in one’s memories and feelings by remembering the past. These recurring seasons can help us to remember things that, otherwise, might be forgotten.

As an inherent quality of human nature, a person wishes to see an order to social life and expects consistent behavior from others. People with consistent behavior are more preferable as friends and inspire trust in those around them. The order formed as a consequence of individuals’ living in harmony can be seen as social rhythm. Just as a social life that respects others’ rights, and acting in accordance with the existing order, is peaceful and harmonious, a social life that runs counter to the idea of order and trust can lead to chaos and unrest.

Arts

Laws prevalent in existence can also be expressed with arithmetical equations. Mathematical curves, fractals, number series, and many other things reflect a rhythmical pattern and a plan. For example, works executed with the proportions of Fibonacci numbers and the golden ratio give aesthetic pleasure to viewers. The eye perceives numerous patterns and motifs formed by ranges of colors, and the ear perceives all melodies and sounds as rhythm. For a person who views creation with eyes of wisdom, the positions of leaves on a tree, a soaring bird, a flowing river, and all of spring’s colorful blossoms are causes of admiration and enthusiasm. Beauty appeals to human nature. And what lies in the essence of all art is aesthetic beauty and harmony, which evoke this feeling of admiration. The human reason, spirit, and emotions have their share from the mysterious activities observed in creation; they express these through art. An artist is essentially inspired by this order and harmony in the universe. If art is the name for sensing this rhythm and harmony in the universe, then the artist is a person who expresses this rhythm in one’s works. Those who grasp this fine meaning and aesthetic beauty in creation can be said to have caught the true spirit in art.

Music is the art where rhythm is sensed best. The patterns and harmony in music perfectly agree with the harmony in nature. Perhaps, how music appeals human feelings and gives us delight is a consequence of such a correspondence. A person’s recognition of this harmony and rhythm in the universe makes one conform to it and become unified with existence.

To conclude, humans have not been left to run wild in this world; an order is needed for their material and spiritual life. The balance, harmony, and beauties existing in creation are reflected in human nature as well. Without a rhythmically working order, the balance of life will be upset, chaos will begin, and maybe the world will come to an end!

How good are we aware of the operations of systems and mechanisms that make us walk?

Costly research and development efforts are under way in centers throughout the world seeking to build walking robots by mimicking human mobility. After 14 years of research, automotive firms built Asimo, a robot which can walk bipedally and climb stairs like humans. Even though the moves Asimo could make matched those of a one year old baby, it was still considered a great success for the robot technology.

Hardships encountered during these research projects proved walking to be a great miracle, apart from normal habits of movement. We often become aware of how extraordinary movement is and that the moves we repeat hundreds of times, such as walking, running, bending, sitting and standing, are blessings granted to us only when we see someone who has lost some of their mobility.

That humans can walk bi-pedally is truly exceptional. Most organisms have a front leaning skeletal structure and walk on four extremities; they only stand upright when absolutely required to, since it is very difficult for them. Human ability to stand upright and walk on two legs truly signifies them as special amongst creatures, and sets them apart from all of creation. The lively, regal posture of dexterous bipedal humans constitutes very important evidence showing they are “the most superior of all creatures.”

The multifunctional, flexible nature of our skeletal system enables us to complete very simple moves automatically. Walking seems to be a very easy task, however, it occurs as a calculated outcome of many factors, such as determination of stepping distance, the toning of corresponding muscles of the same and opposite direction, relaxation and contraction levels, and relocation of the body’s gravity center.

Walking takes place via the coordinated works of the locomotor (musculoskeletal) system, motor control system, and balance-coordination system.

Locomotor (musculoskeletal) system

The framework of the human body is built together with 206 bones of variable hardness. With their strong nature and capacity to endure extra weights, bones takes up 20% of a body’s mass, and are the major load bearing part of the body’s structure.

The main part of our skeleton is the vertebral column. It consists of 33 small bones, known as vertebrae, positioned on top of each other. Wear-preventing discs are found in between vertebrae to protect against motion related wearing over time. As the vertebral column holds the weight of the upper body, it is created in a way to keep the body upright. The spinal cord inside the channel that is surrounded by the vertebral column is a very important signaling network providing coordination between the brain and other organs.

Joints and ligaments are among the moving parts of our body. The most important joints for walking are the hips, knees, and ankles. The curvy shape of the foot and its contact to the ground at three spots supports bones against body weight and helps with balance. This is why flat footed people struggle with walking and get tired easily. The curves of our spine at the neck, back and waist regions, and the hips, knee joints, and curvature of the foot, are perfectly shaped for standing upright and walking.

In order to move we need a muscle system along with the skeletal system. Muscles are made up of thousands of contractible muscle fibers. There are more than 6 billion muscle fiber motors in the human body. We walk, run, eat, breathe, talk and do many more moves by using ability granted to muscles. Approximately 35 muscles in each leg, and around 100 muscles in the whole body, function during walking.

Ligaments and tendons are links that secure bones and muscles together; they also help to stabilize joints, thus when standing, joints remain in place without muscles contracting.

Four different mechanisms are involved in walking:

1. Proper upright posture and maintenance of balance during walking
2. Forward motion of body via muscle power
3. Reduction of shock-impact effect while stepping
4. Maintenance of motion with the least amount of energy.

A series of movements is generated in the legs to provide a forward motion and these are constantly repeated. These constant repetitions are called the “walk cycle.” The “passing pose” is defined as the time frame when the leg is in the air, and the contact pose is the phase during ground contact. In the middle of the contact pose, even though body is in balance, because of the forward momentum of the body, balance is lost, thus the body leans forward. Balance is then restored by stepping on the ground with the leg in the air. As a result of this rhythmic loss and restoration of balance, the body moves forward.

In a person standing upright, the center of gravity is in front of the fifth vertebra. At the start of a walk, the body leans forward to carry the center of gravity towards the front; then the initiation of the motion via forward transfer of the power with toes and joints takes place, followed by the lifting of the heels, the bending of the knees, and the lifting of the foot, thus displacing the center of gravity of the forward leaning body towards the front.

Balance should be maintained when one leg is lifted in order to let the other leg carry the load of the body’s weight. The gravitational center of the body is located in the distance between the two legs since each leg is located on the side. Body balance is maintained by the contractions of dorsal muscles located across the side of the stepping foot, working in parallel to support and transfer body weight to the foot via the hip and femoral muscles. These events happen so quickly that we often do not even notice all the complicated processes.

The great Sufi figure Abdul-Qadir Gilani was often asked questions such as, “Master, show us a miracle.” He would stand up to walk three to five steps and sit back down. Everybody was confused, looking at each other. One person among them was heard saying, “Master, excuse us but we can all do that as well.” Gilani replied then, “Is there a greater miracle than walking? You see it, but do not understand.”

Motor control of walking

Bodily motions are controlled via the primary motor centers that are located on the side and cortex region of the brain. These centers are created in a way to prepare and organize motor programs involving body movements, and to integrate them with the proprioceptive memory. This synthesis of information enables the adaptation of motor commands to the present posture of the legs and arms regarding intended moves.

A desire to make a move is a necessary prerequisite for the stimulation of muscles pertaining to it. If we want to hold something, we can easily do it; when we want to raise our arm, our elbows bend; to run or walk, our leg muscles start to move and work. How do all of those moves happen? Is our desire enough to do so? Can the guidance of all the bones and muscles, working together towards the same target, happen by itself or occur via coincidences?

In order for muscles to move, our thoughts must be relayed to them and this is provided by the nervous system and nerve network. There is an amazing communication network present in our body. In case of an intended move, an electric signal is sent by the brain. During this journey, which seems to be complicated, the signal arrives at the spinal cord and then quickly diverts to the corresponding organ. Millions of motors that make up the muscle are stimulated by the electric signal, contracting the fibers instantly upon reception of the signal. In order to do a coordinated move, it is necessary to know the related body organs’ positions and their relations to each other. Millions of transmitters that provide this information have been placed throughout the body. This data come from the eyes, the inner ear’s balance and sensory organs, muscles, joints, and skin. There are billions of micro receptors located in muscles and joints programmed to send instantaneous positions of the body to the central nervous system. In every stage of a move, the positions of the muscles are reported instantly to the command center by these micro receptors inside the muscles. New commands are given to the muscles based on the assessments made here. This way, each second, billions of bits of information can be processed and assessed.

The cerebellum is another center that is in charge of functions such as maintenance of balance during walking and standing, carrying out proper and coordinated moves with visual control, providing coordination among muscle groups, promptly starting and stopping movements, and the maintenance and organization of normal muscle toning. The cerebellum is tasked primarily with hastened muscle activities like running, typing, and talking. Thus, fast moves necessary for the balance system are sustained properly and successively without abnormal oscillations.

Specific motion templates have been programmed in the spinal cord for all muscle-covered regions of the body. Rhythmic movements, such as forward and backward motion of the legs and arms, and coordinated activities of other body parts in tandem with walking, are controlled here. The task to control repeated moves like walking is assigned to the nerve network consisting of the spinal cord, brainstem and cerebellum.

Balance and coordination system

One of the requirements to walk and move is to stay in balance. Despite our advanced musculoskeletal system, without balance, this system of ours would be useless, or even dangerous.. Our balance system, which is in charge of the instantaneous control and fine adjustments regarding our body, is granted to us as a blessing of Divine compassion.

There are three systems that provide data involving the positions of the head and body: vestibular system (the apparatus of the inner ear), visual senses, proprioceptive senses

The vestibular structures are an essential part of the balance system. They are found in the inner ear, and are small and complicated systems. This 6.5 mm diameter wide system is composed of semicircular channels that contain specific fluid and ciliated sensory cells that cover the inner linings of the channels. This system constantly reports information involving our status in the outer world and instantaneous changes to the balance system.

When we move, the fluid inside the semicircular inner ear channels get displaced; this motion vibrates the cilia. This vibration causes an electric signal to generate in the cells. This electrical signal is then transmitted to the cerebellum; received information gets evaluated instantly in the cerebellum. This system is created to function autonomously without our will and control. When this system is impaired, balance disorders occur, such as dizziness.

Information regarding our position in the environment and the relative status of the environment according to us is sent to the cerebellum and brainstem via our visual senses.

Proprioceptive senses are formed via the activities of tension receptors built in muscle fibers, tendons and joint capsules. These are sensitive to motions and positions. These receptors regularly provide information to the central nervous system. The cerebellum receives information from all the muscles and joints of the body, including the eyes. These inputs are analyzed very promptly at the cerebellum, and the relative gravitational position of the body is finely calculated, thus the proper motions of muscles are determined. The resulting response is relayed towards muscles by nerves. These events take place in a time frame that does not even last for a hundredth of a second. We easily walk, run, and do complicated moves without feeling any of these activities happening inside us. Yet the calculations taking place in our body even for a single moment of those movements can fill thousands of pages.

To understand the fascinating side of our ordinary movements, let’s consider a person climbing up the stairs. First, the eyes scan the surroundings, then the three dimensional information of positions acquired from the materials and belongings in the environment are transmitted to the brain. Once received, the information is analyzed and the necessary commands are sent to the target organ from the motor centers of the brain. Commands passing through related tracks and centers finally arrive at the musculoskeletal system. Many factors, like the height of stair steps, length and depth of the foot step, center of gravity and position of the body, are calculated and determined almost instantly.

Proprioceptive signals constantly report the positions of organs, like the arms and legs, to the command center. Inner ear receptors are in charge of the prompt transmission of information necessary for balance, like motion, speed, and direction of the body. These inputs are calculated in milliseconds at corresponding centers in order to maintain the coordination and harmony of the entire body. A person who is running up the stairs may think to jump a couple of stairs. This change of command is rerouted to the locomotor system as a new and different command from the brain. All of these processes are completed in centiseconds. In the mean time, the head, shoulders, and arms are employed for rhythmic oscillations in order to adapt to the overall body momentum.

In conclusion, standing and walking are miraculous and take place via thousands of interrelated activities. Nonetheless, we usually do not notice any of the thousands of processes that are constantly taking place. One hopes that every blessing we have is seen through the window of thanksgiving and appreciation.

Zeno of Elea was a pre-Socratic Greek philosopher of southern Italy and a member of the Eleatic School founded by Parmenides. He argued that an object in motion can never pass from one position to another, because between the two there is always an “infinity” of other positions, however close, that must be successively traversed in the course of the motion, and this “infinity” can never be exhausted. David Hilbert is a German mathematician who postulated a hypothetical hotel with “countably infinitely” many rooms, all of which are occupied. Since the hotel has “infinitely” many rooms, we can move the guest occupying room 1 to room 2, the guest occupying room 2 to room 3, and so on, and fit a newcomer into room 1. By repeating this procedure, it may be argued that it is possible to make room for any finite number of new guests, although every room of this hotel initially contains a guest.

The following two quotations from two contemporary authors may provide more substance about the nature of the problem:

On the other hand, involvement with the infinite brings with it a huge range of difficulties. In particular, there are the many puzzles and paradoxes that have been outlined in the pages of this book. Moreover, there are the many quite fundamental problems that arise for such apparently simple notions as counting, adding, maximizing, and so forth. Because we are so firmly wedded to limit notions-“best,” “first,” “greatest,” “maximum,” and so forth-that do not sit easily with the infinite, it is very hard to see how we can make our peace with the infinite.

The infinite has always been a slippery concept. Even the commonly accepted mathematical view, developed by Georg Cantor, may not have truly placed infinity on a rigorous foundation.

In the present article, we attempt to summarize Rene Guenon’s (1886-1951) alternative way of thinking on the idea of infinite from the perspective of the traditional metaphysical science. Much more detailed presentation of his perspective can be found in his (1886-1951) valuable study The Metaphysical Principles of the Infinitesimal Calculus from which we will extensively quote here.

Guenon considered mathematics as providing a particularly proper symbolism for the expression of metaphysical truths to the extent that they are expressible. However, he states that “in order for this to be so it is above all necessary that these sciences be rid of the various errors and confusions that have been introduced by the false views of the moderns.” To follow Guenon’s paradigm it is necessary to start with the metaphysical notion of the universal-All which comprehends all possibilities, the non-manifested as well as the manifested Universe, that is, the cosmos. The universal All leaves outside itself only the impossible that is a pure nothing. A determination is to define a certain domain of possibilities in relation to all the rest which is expressed by Spinoza (1632-1677) as omnis determinatio negatio est (all determination is a negation). The first of all determinations is Being itself. “Number is only a mode of quantity, and quantity itself only a category or special mode of being, not coextensive with it, or more precisely still, quantity is only a condition proper to one certain state of existence in the totality of universal existence.” Number, space, and time are all determined conditions.

The Infinite, understood in its true, metaphysical sense, has no limits since its opposite, finite is synonymous with limited. Therefore, according to Guenon,

… one cannot correctly apply this term to anything other than that which has absolutely no limits, that is to say the universal All. Furthermore, there can obviously be only one Infinite, for two supposedly distinct infinities would limit and therefore inevitably exclude one another.

He further states, “The Infinite, in its true sense, can have neither opposite nor complementarity.” The scholastic distinction between “the infinite in a certain respect” and “the absolute infinite” cannot be accepted. If a thing is not limited in a certain sense or in a certain respect than one can legitimately conclude that it is limited in no way at all, and since a determined thing does not include every possibility, as such it can only be finite.

Given any number, one can form the next by adding a unit gives the sequence of numbers to us. Therefore, we cannot actually reach its limits. However, the impossibility of reaching the limits of certain things in the manifested Universe should not cause the illusion that these determined things have no limits at all. In order to replace the false notion of “determined infinite,” Guenon introduces, the idea of the indefinite, which is precisely the idea of a development of possibilities the limits of which we cannot actually reach; and this is why we (Guenon) regard this distinction between the Infinite and the indefinite as fundamental to all questions in which the so-called mathematical infinite appears.

According to Descartes (1596-1650), the indefinite is that of which we do not perceive the limits, and which in reality could be infinite. On the contrary, Guenon affirms that

(T)he indefinite cannot be infinite because it always implies a certain determination, whether it is a question of extension, duration, divisibility, or some other possibility; in a word, whatever the indefinite may be, and according to whatever aspect it is considered, it is still of the finite and can only be of the finite.

The idea of an “infinite number” understood as “the greatest of all numbers,” or “the number of all numbers” is contradictory. The impossibility of an “infinite number” can be established by various arguments:

(T)o every whole number (integer) there corresponds another number equal to its double, such that one can make the two sequences correspond term by term, with the result that the number of terms must be the same in both; but there are obviously twice as many whole numbers as there are even, since even numbers alternate by twos in the sequence of whole numbers; one thus ends up with a manifested contradiction.

Guenon insists that number, despite its indefinitude, is by no means applicable to all that exists and the multitude of all numbers cannot constitute a number, which, moreover, is finally only an application of the incontestable truth that what limits a certain order of possibilities must necessarily be beyond and outside that which it limits.

On the other hand, the idea of multitude, contrary to that of number, is applicable to all that exists which allows one to speak of the multitude of divine attributes for example, or again of the multitude of angels, that is, of beings belonging to states that are not subject to quantity, where, consequently, there can be no question of number.

Number itself can also be regarded as a species of multitude, but on the added condition that it be a “multitude measured by the unit” according to the expression of Saint Thomas Aquinas (1225-1274).

The term “indefinite” consists of something unfinished. The “non-measured” is that which has not yet been defined, which is only incompletely realized within manifestation. The multitude of all numbers is “innumerable” or “non-measured,” which is not to say they are infinite, but merely that they are indefinite.

Guenon calls whole number as true number or pure number. He accepts that the numbers other than whole numbers can be considered as the extensions or generalizations of the idea of number. However, he adds that these extensions are also distortions. According to Guenon, numerical quantity has a discontinuous character, whereas spatial or temporal magnitudes, for example, are continuous quantities. “Between these two modes of quantity is a difference of nature such that a correspondence between the two cannot be perfectly established.” He distinguishes the arithmetical unit from the “units of measurement,” which are magnitudes of another sort than number, notably geometric magnitudes. He defines a continuous quantity as an extension-however small it might be that will always remain indefinitely divisible.

Guenon is against atomism, which necessarily implies the discontinuity of all things. He argues extension cannot be composed of indivisible elements, for these elements would have to be extensionless to be truly indivisible, and a sum of elements with no extension can no more constitute an extension than a sum of zeros can constitute a number, that is why points are not the elements or parts of a line; the true linear elements are always distances between points, which latter are only their extremities. Points multiplied by any quantity at all can never produce length, since, rigorously speaking, they are null with respect to length; the true elements of a magnitude must always be of the same nature as the magnitude, although incomparably less: this leaves no room for indivisibles.

Further,

The point, which, being indivisible, is by that very fact without extension, that is, spatially null, but which, as we (Guenon) have explained elsewhere, is nonetheless the very principle of all extension.

For Guenon, Zeno of Elea’s arguments are against atomism and indeed, they prove that without continuity there would be no possible motion.

It is this very conception of motion that is in error, for it amounts in short to regarding the continuous as if it were composed of points, or of final, indivisible elements, like the notion according to which bodies are composed of atoms; and this would amount to saying that in reality there is no continuity, for whether it is a question of points or atoms, these final elements can only be discontinuous.

And, “The possibility of motion presupposes the union, or rather the combination, of both temporal and spatial continuity.”

We consider Guenon as an important and prominent example of thinkers who tried to remind people of the traditional metaphysical ideas. This metaphysical perspective does not share the modern tendency to attribute more importance to the practical applications of science than to science itself. This perspective attempts to link science back to principles of a higher order so that a particular science can be used as a support for elevating oneself to a higher knowledge.

In addition to all these questions, there is one aspect of time that will attract a believer in God and that is time’s fascinating connection with the act of creation and the continuity of physical processes. In this article, we choose to probe down to subatomic distances in an attempt to understand the act of creation and clarify the meaning of time, leaving cosmological time aside. Along the way, we will visit what some Muslim scholars have said regarding the issue. It is, however, useful to look first at the view of modern physics on time.

The classic and modern view on time in physics

The best known physicist who wrote on time is Newton. For Newton space and time were separate and were backgrounds on which physical processes evolved. Therefore, time can exist with or without events. As, according to Newton, time is a linear continuum of instants and each instant exists by itself, we can only talk about the existence of the present. In this approach time is absolute, meaning that it is the same everywhere in the universe. So your “now” is the same with my “now” no matter how fast each of us is moving. One consequence of this classic and commonsense view is that time-travel is not possible. At the beginning of the twentieth century, after the work of Hermann Minkowski and Einstein’s relativity theory the question “What is time” received the answer, “time is the fourth dimension,” which has become almost a cliché. It is not only difficult for us to visualize the fourth dimension itself, but also its relation with space. In Minkowski’s space-time, a time dimension can turn into a space dimension by a rotation, just as the length of an object can turn into its height by simply rotating the object. Actually, it is wrong, after all, to think of space and time as two independent things. As soon as there is space, there is time by default. An event happens in space-time at a particular space-time location and space-time spans all through these locations on which many other events happen. In 1919, in an interview he gave for The New York Times, Einstein explained the shift in the view of space-time: “Till now it was believed that time and space existed by themselves, even there was nothing, no Sun, no Earth, no stars, while now we know that time and space are not the vessel for the Universe but could not exist at all if there was nothing, no contents, namely, no Sun, no Earth, and other celestial bodies.”1

The new notion of space-time has also changed the deep-seated belief that only the present is real, because in the space-time present, the past and the future all exist together. “Physicists prefer to think of time as laid out in its entirety-a time space analogous to a landscape-with all past and future events located there together. It is a notion sometimes referred to as block time. Completely absent from this description of nature is anything that singles out a privileged special moment as the present or any process that would systematically turn future events into the present, then past, events. In short, the time of the physicist does not pass or flow.”2 The above view of the universe, described by Paul Davies, has been called “The Block Universe”; this view has also been supported by many philosophers like Leibniz and Spinoza. It is not wrong to say that it is not time that flows but it is us who are flowing by changing our space-time location in the space-time landscape at each instant. Simply put by Aristotle, “Time is motion.” There is a very nice example given by Rumi, also used by Imam al-Rabbani, given to explain the non-real nature of matter, which also explains how space-time comes into being with motion. Imagine a stick that is spinning at high speed with a fixed light on one side. Even though the light is fixed at just one point, once the stick is spun at high speed, we see a circle of light.

The theory of special relativity has also revealed that time is not absolute: Time actually slows with motion and stops when the speed reaches that of light. This effect becomes apparent only at speeds close to the speed of light at the quantum world and is not noticeable to us since the human scale motion is far too slow. The relative nature of time enters the general relativity theory as well with a theory that explains gravity as the curvature of space-time. One of the striking features of the equations of general relativity, which was noticed first by Godel in 1949 and then by many others, is that they allow for closed time-like curves in space-time. This means the possibility of time travel, at least theoretically.

A time scale we know nothing about

Modern view of time as explained above is valid up to atomic scale and has taken its place in the basic structure of quantum theory. However, science has no experimental ground to reveal anything about the nature of time at Planck’s scale or at smaller levels. The Plank scale corresponds to a time of 10-44 seconds and a distance of 10-35 m. This is a distance which is a hundred times a million times a million times a million smaller then the atomic nucleus. At such distances the quantum theory does not work. We have neither the necessary theory nor the necessary experimental facility to say anything about time.3

Relation of time with the act of creation

Long before revolutionary changes in the view of physical time at the beginning of the twentieth century there were always metaphysical explanations for what time really is; one of these was that of René Descartes. In his meditation on God’s existence, he argues that God must and does continually recreate the world at each instant. Therefore, time is a divine process of recreation. There are two points in Descartes’ statement. One is that creation is a continuous act and the other is its relation with time. We are all aware that the continuity of creation is found in the teachings of the Torah, the Bible, and the Qur’an. It is not that God created the universe at the beginning and left it to evolve according to laws. When it comes to the relation of creation to the essence of time, Descartes view, at first, may be considered to be a metaphysical speculation. But it may also be an inspiration which Descartes received from a divine scripture.

Many Muslim scholars as well have taken Qur’anic verses on creation as references for their meditations on the nature of time. Ibn al-Arabi, in his Kitab Ayyam al-Sha’n writes about the structure of time and takes the Qur’anic verse Every day (yawm) He is in a new manifestation (sha’n) (Rahman 55:29) as a reference. The Arabic word “yawm” which means day is interpreted not as a time period that we call “day” but as a day in God’s Divine Presence. In Qur’an, the special word “sha’n” is used while talking about God’s acts to distinguish these from human acts. Besides sha’n (God’s act of creation) is always associated with the smallest and finest of times that leads to the fact that His acts happen with an incredible speed. There are few Qur’anic verses about the incredible speed of creation. One is:

God creates whatever He wills; when He decrees a thing, He does but say to it “Be!” and it is (Al Imran 3:47).

And the other is:

Our commands are done within the blink of an eye (Qamar 54:50).

Both verses imply not only that God creates whatever He wills without any difficulty but also the speed which His acts and His commands are carried out. Therefore, most scholars interpreted verse 55:29 as “God is in a new manifestation or at an affair at each instant.”

Now going down to sub-atomic levels where we come closer to the recreation at each instant and reading the following lines from The Words by the Turkish Islamic scholar Said Nursi we are better able to understand the essence of time:

“Indeed, the transformations of particles are the motion and meaningful vibrations that proceed according to the dictation and principles of “The Clear Record” (Imam-i Mubin) which is a title of Divine Knowledge and Command and is the arrangement of the past origin and future progeny of everything in the World of the Unseen. They proceed by means of transcription from “The Clear Book” (Kitab-i Mubin), which is a title for Divine Power and Will and is formed of the present and the Manifest World and consists of the free disposal of that power and will in the creation of things. Thus, this motion and meaningful vibration proceed from the writing and drawing of the words of Power in ‘The Tablet of Effacement and Reaffirmation,’ which is a metaphorical page, and the reality of the stream of time.”4

The terms Imam-i Mubin and Kitab-i Mubin are used in the Qur’an in the following verses respectively.

And we have vested (the knowledge and authority) of everything in the manifest record. (Ya Sin 36:12)

The unbelievers claim, “The Last Hour will not come upon us.” Say: “Nay, but, by my Lord, Who is the Knower of the unseen, it will most certainly come upon you.” Not an atom’s weight of whatever there is in the heavens or in the earth escapes Him, nor is there anything smaller than that, or greater, but it is recorded in a Manifest Book. (Saba 34:3)

The term Imam-i Mubin, which is interchangeably used with Lawh al-Mahfuz by many Islamic scholars, is associated with Divine Knowledge and Command. Since Divine Knowledge encompasses everything, the Imam-i Mubin includes the past, present and future as well as the world of unseen. Time from azal (eternity in past) to abad (eternity in future) are found in Imam-i Mubin. Kitab-i Mubin, however, embraces only the present. We understand from the above Qur’anic verse that, Kitab-i Mubin accommodates the inward (batin) meaning of creation as well as the outward (zahir). The passage of time lies in a close relationship between Imam-i Mubin and Kitab-i Mubin. Time passes when God’s command proceeds from the Sphere of Divine Knowledge to the Sphere of Divine Power. Since we are restricted in time and are only witnesses to the Book of the Universe, that is, Kitab-i Mubin, we see only the present, instant after instant. In a way, we witness recreation instant after instant, a creation that continues completely unnoticed due to the incredible speed of God’s commands from Imam-i Mubin to Kitab-i Mubin. The interpretation given by Ibn al-Arabi to the Qur’anic verse Nay, (although they admit that We were not so,) they are in a confused state of mind about a new creation (after destruction) (Qaf 50:15) is that: There is continuous renewal of creation in every instant. What people see in the first instant is not identical to what they saw in the previous instant. So people are in confusion about this. Actually, through the manifestation of His Names, God continuously creates, annihilates and re-creates the universe.

Creation, time and the continuity of physical events

Keeping in mind the connection between Imam-i Mubin and Kitab-i Mubin and the renewal of creation at each instant, we can now contemplate on another puzzling issue: The continuity of physical events. Even before quantum mechanics revealed the discontinuous nature of sub-atomic particles, some philosophers argued that it is the mind’s apprehension of discrete events as being continuous that leads us to conclude that things around us are continuous. The best known macro scale examples are watching a motion picture in cinema which is actually seeing 60 images one after another in one second, and looking at a burning light bulb which is, in fact, light that is flickering many times. Even though these processes are discrete in nature, our mental snapshots one after another gives the impression that these processes are continuous. How about the discontinuity in the micro world? Professor Whitehead nicely explains the discreteness of the (motion of) electron in the following lines:

“It is not wrong to assume that an electron does not continuously traverse its path in space. The alternative notion as to its mode of existence is that it appears at a series of discrete positions in space which it occupies for successive durations of time. It is as though an automobile, moving at the average rate of thirty miles an hour along a road, did not traverse the road continuously, but appeared successively at the successive milestones remaining for two minutes at each milestone.”5

At this point it is agreeable to look further down to the distances that are smaller than Plank length, the smallest physical arena we can think of, where physics meets metaphysics and the act of creation takes place. This locus may well be the realm of discontinuity as well, as it is at this locus that materialization takes place. At this locus we may be able to witness God’s repeated acts of creation and annihilation and re-creation again, if we were able to probe down so far. So at the sub-atomic level, the transformation of particles can all be viewed as the vibrations that occur while God’s command is carried out from Imam-i Mubin to Kitab-i Mubin and back to Imam-i Mubin. Hence, there is the continuous cycle of coming into existence and dying in the Book of the Universe, if we call not appearing in the universe for a fraction of a fraction of a second dying, of course.

Taking the Qur’anic verse 28:886 as a reference, Nursi says “Existence continuously comes from God and returns to and perishes in God’s Knowledge”7 and he claims that there is no absolute nothingness (‘adam) since nothing can escape from God’s Sphere of Knowledge. In other words, even if something ceases to exist in the physical universe, or something that has not been even created or seen yet has some mode of existence, as it exists in God’s Knowledge. Because in God the ideas of all things are fixed, Imam-i Mubin, the title of His Knowledge, is also associated with a’yan thabita, which means fixed prototypes, where the latent realities of things exist.

Time versus dahr

Other than the term “zaman”, meaning time, the term “dahr” is also used in some Qur’anic verses (45/24).8 Scholars give different views on the use of the latter word; the widely accepted one is that “dahr” means a long period of time, an eon. Sadruddin Konevi calls God “Dahr-i Daim” meaning “everlasting dahr” and identifies this as the eternal time which does not have relative aspect but includes relative and temporal time (zaman). According to him, dahr is the essence of time. This helps us to understand the Prophetic saying: “Curse not dahr, for God is dahr.”

Conclusion

We have seen what physics has to say about time, but we will never know if science can grasp the whole truth. Moreover, science cannot tell anything about the nature of time for and smaller than “Plank era.” We either stop at that point and do not question further or break the tenets of positivism. Islamic scholars and intellectuals have always linked time to God’s act of creation. Said Nursi further linked the passage of time to the relation between Imam-i Mubin and Kitab-i Mubin. Being a creation in space-time we are bound to relative time and have only the perception of events in time. But it may well be that innermost essence of time lies not in the material world but in the Unseen.

The role of mathematics in understanding nature

Mathematics is a discipline of thought. It helps to develop our way of thinking and is an exercise in improving our intelligence. Mathematics can be considered as another kind of language, a language very different from that of a spoken language. When it is hard to convey our thoughts in terms of words, or our words become insufficient to express our thoughts, mathematics may be used as an alternative. On some occasions, expressing ideas via mathematics might be more concise, much clearer and more understandable. Although mathematics is considered to be a separate branch of science, in fact it is related to all branches of science. Nowadays, even in biological and social sciences, extensive studies are being conducted using mathematics.

Engineering was one of the earliest application fields of mathematics. It has strong links with mathematics as well as physics. Many engineering problems can be considered as an application of mathematics and hence applied mathematicians and engineers share common research areas. Engineers try to improve the quality of life by designing new products and in the design process, geometry and mathematics play a vital role.

Since the first day of existence on the world, mankind has tried to understand and formulate the surroundings and events that take place around them. They have investigated the world and the cosmos and accumulated knowledge. Each question that was answered yielded more questions to be answered and the more the knowledge that was acquired the better the extent of our ignorance about the universe was understood.

The universe has been established in a very complex orderly manner. The magnificent order observed cannot be expressed well in words, but may also be expressed using mathematics. A person who develops their knowledge of mathematics can understand more about this supreme order. For example, the universal gravitational law, which describes the movement of planets, can best be understood through mathematical equations, while the solutions of the equations yield the well-known elliptic paths. The concept of infinity that is attributed to the Creator can be realized through the concept of infinity that is frequently used in mathematics. So mathematics is an essential tool in developing our understanding of the nature and universe. It is essential also in applying the principles of physical laws in nature to improve our quality of life. The design of an airplane requires extensive mathematical calculations and applications of physical laws.

Finally, it should be noted that mathematics also has its limits, as it is something that has been developed by human beings and may not be sufficient to express the total order and all physical laws. Chaotic motion, a very complex order, was developed recently to understand some phenomena that do not obey the rules of deterministic motion. A daily example of such motion would be atmospheric motion. With even super computers and satellite technology, the path of the hurricane Katrina could not be predicted precisely due to its largely chaotic behavior and these errors cost thousands of lives.

Basic engineering principles and their applications in nature

First, let’s briefly describe some of the fundamental engineering courses and their aims. Dynamics is the science of motion. It models motion, describing the relation among displacement, velocity and acceleration. The specific type of motion and its causes, such as forces, movements, impulses etc. are examined. Dynamics deal with solid bodies while fluid mechanics basically deals with liquids and gases.. In the context of fluid mechanics the rest states of fluids as well as their motions are investigated. The strength of materials deals basically with the design of structures and mechanical parts to loading conditions. Under a given loading condition, what would be the best design for withstanding the loads while using the minimum amount of material? Materials science deals basically with the mechanical properties of various materials and the causes (microstructure etc.) of those properties. Proper selection of the materials to perform the required task is another important issue.

Living organisms can also be considered as some sort of design, but of course they are different from man-made designs. Living organisms, whether they are plants, animals or human beings, are designed to perform a specific predetermined task. The organism has to move, find food, safely operate and resist the forces that act on it throughout its life, and it must reproduce. Therefore, organisms have to be designed (or more precisely created) according to the principles of engineering. The development of technology drew attention to creatures and the underlying engineering principles in their structures. Extensive research on living creatures revealed a clear conclusion: Designs applied in nature are much more sophisticated then the ones humans come up with.

Bernoulli’s principle is a fundamental principle in fluid mechanics. Basically, the principle states that when the velocity of fluid increases the pressure drops and visa versa. The lift force generated in the wing of a plane is explained with this principle. Air separates in front of the wing and reattaches at the back. When the upper surface of the wing is slightly curved and the bottom flatter, the air particles in the upper part travel a further distance at a higher velocity and meet the particles traveling under the wing at the back. The relatively higher velocity on top causes a pressure difference in the lift direction and this lift force balances the weight of the plane. Many applications of Bernoulli’s principle can be found in living organisms. A fish moving in water is a good example. In particular, fish that swim at great speeds, like the tuna, have distinctive body shapes: The mouth of the fish is at the front where the fluid comes to rest and the pressure is very high, making the fluid intake of oxygen easier. The heart is located at the minimum pressure point to make it easier for it to beat. The eyes are located on a precise saddle point, a place which is not affected by velocity changes. Since the pressure is constant for all ranges of velocities, vision is not distorted by movement. Another example is the human body. When one breathes in the fluid velocity in the nose increases and pressure drops. The outer pressure is higher than the inner pressure and the walls tend to collapse. If bones were found at the tip of the nose, they might easily break when excessive force was present. We need some other material to sustain the shape yet be elastic enough not to break down. Cartilage is the best choice in this case, as it has both strength and elasticity. Our ears are also made from the same material. If bones were used instead of cartilage in our ears, resting our head on one side would be painful or even cause damage to the ears.

Insect flight is another important issue and has attracted considerable research recently. Fluid scientists now realize that insect flight is much more developed than our flight techniques. Turbulence is the main issue. In turbulent flow, the fluids move in erratic paths colliding with each other, forming eddies and irregularities. This is a dangerous state, especially for planes, and increases the friction forces between fluid and structure. Therefore the maintenance of a regular flow (laminar flow) over the wings is advantageous. However, all insects benefit from turbulence and some portion of their lift is gained from eddies that are formed over their wings. Mechanical insect robots are built to understand insect flight. Insects have movable elastic wings, but aircraft only have immovable rigid wings. Movable elastic wings would certainly improve the flight of planes and their maneuverability, but extensive research has to be done before these designs can be safely implemented.

The bumps on the fins and heads of some whales are not accidents of nature. They were given to them by the Creator for some very special purposes. They decrease the friction (drag) force by 10% and increase the lift by 5%.1 When some have the effect of decreasing drag, they can also decrease lift and visa versa. This effect of both decreasing drag and increasing lift, which can be observed in whales, is very uncommon in fluid mechanics.

Streamlining is a very important issue for an object that moves in a fluid. Fluid particles move around an object that follows a path. Roughly speaking these paths are streamlines (in a steady motion) and it is a general rule that abrupt distortion of these streamlines should be avoided. Smooth changes in the streamline help to reduce the friction force between the object and fluid. All organisms, particularly those that move at greater speeds, have been created in accordance to streamlining principles. In these you can find many species of birds and fish, such as dolphins, sharks, whales etc. The friction reduction caused by the shape of a dolphin is still a controversial issue in science and the underlying mechanism has not yet been well understood.

An example of the strength of natural materials can now be given. Our bones are optimum structures, combining strength with lightness. In modern buildings, 60-70% of the buildings consist of the skeletons, which carry the loads and moments. In our body, our skeleton is only 1/7th of our body weight. Bones have inspired a new generation of lightweight structures. For instance, a bridge inspired by the backbone was recently designed.2 When a longitudinal cross-section is taken from a femur, some curved lines are observed. Recent numerical simulations revealed that these lines are to be found in one exact place and their configuration increases the strength of the bone. Our backbone and the muscles around it withstand very high loads, equivalent to 7,000 Newtons or approximately 700 kilograms of weight.3 The bones of mammals are hollow inside to increase strength. The inner to outer ratio of the radii is at the optimum range, between 0.4 and 0.7.4

Hardness is another important issue in some applications. Seashells are the leaders in this issue. Their microstructures are being investigated under electron microscopes to invent new materials with extreme hardness properties. Micro-cracks inside a material grow over time, finally leading to failure. This is a major problem in turbine blades and this phenomenon is responsible for some plane crashes. In seashells, micro-crack inhibiting mechanisms are inserted to prevent crack growth. Inspired by spider silk and the microstructure of bird feathers, a new generation of bullet-proof waistcoats has been developed.

Owls are very silent flyers; they need to be so in order to approach rodents as rodent ears are highly sensitive to sound. Recent investigations have shown that the special geometry of their wings results in this silent flight. Their feathers are placed to form fringes on their wings. The technology might be mimicked to reduce the noise generated in planes.5

A recent engineering discipline is robotics. There are industrial robots, which are designed to perform some very special tasks. But there are also robots inspired by living organisms. A new robot is designed to mimic caterpillar motion so that it can be stable enough in a hazardous region, pass through small gaps and detect humans who are alive under debris.6 By mimicking the motion and body of a scorpion, a military robot was designed with a camera and sensors to safely operate in a battle region.7 Of course there are human-like robots that are designed to mimic our motion and activities. The developments in robotics teach us a very important lesson: All animals are much more sophisticated in their locomotion, actions, and behavior and it is extremely hard to mimic those. A robot that can move freely like a cat and climb a tree yet maintain its balance has not yet been produced. Our robots are very slow in motion, and their stability in movement is an important technological issue that requires extensive sensors and control designs.

Newly developing engineering branches

As mentioned above, one of the newly developing branches of engineering is robotics. Day by day, better robots are being designed and those designs try to better mimic animals and humans. Some 50 years ago, a human walking might be considered a simple issue, but now we know that comfort in walking and excellent balance in such movement are very complex issues.3 Each new design in robotics adds to our knowledge of understanding animal locomotion and behavior and how miraculous their designs are. Some people think that robots may take control of the world in the future. Yet this is simply not possible: If humans are to design them, there is no way that such machines can be superior to the designers.

Other promising new fields are the MEMS (Micro-electrical machinery systems) and nano-technology. These are design attempts on extremely small scales which actually mimic some micro biological systems and micro-physics. A vertebrate consists of an enormous number of cells, while the chemical and physical events that take place inside the cells and their establishment as a system are crucial parts of staying alive. It is extremely hard to design at the micro and nano scale and it is likely that research in this field will reveal more about understanding the art of God.

When we look at our bodies, we see that everything is taken care of already: respiratory systems, nervous systems, and all others work without our control. It is as if we dwell in a palace where everything is already optimized and automated for our living conditions³ Therefore, being the resident of this palace, the ego is responsible for using these given faculties in a way to keep harmony between inside and outside. This tells us that it is the ego that must emulate the concept of “accelerated motion.” If we rephrase this concept, we can say that it is the ego that must undergo a continuous change in order to achieve beauty and order inside and establish harmony between inside and outside. Considering that our knowledge of ourselves and of the world around us is limited, how can we educate our egos to achieve this harmony? Let’s make a journey into the major human to answer the question concerning the minor universe.

First observation

We see that everything in the universe changes, and nothing remains unchanged. Slow or fast, nature is in a continuous motion and change. Thus nature is never the same twice. Interestingly, within this continuous change, we see periodicities. Although things are never the same on a small scale, we see repeating epochs on a larger scale, such as the alternation of day and night, the cycle of the seasons, and the birth-growth-death period in all living things.

Second observation

We also observe that the great cycles of change that take place in the universe conceive a criterion or a point around which they rotate. For example, the planets assume the sun as their axis of rotation; the stars take the galaxy center as their axis of rotation.

Third observation

When we look at nature, we see that there is solidarity between the living and non-living things through which non-living ones become sustenance for the living ones. We also see solidarity among living things⁴ to sustain each others’ existence on Earth so that none of the species leave the stage.

Fourth observation⁵

Another fact that catches the eye is multi-tasking in nature. For example, we see air as a conductor of light, sound and heat; we see it entering our lungs and participating in our bodily reactions. Again the same air goes into other living things and functions in those systems in harmony. Soil is another example. We see the soil as a nest for all kinds of seeds, which function differently from each other; and the same soil is used for the construction of the bodies of living things and even their homes.

In order to have the beauty and the order of the major universe reflected on the minor one, i.e. human, the change and periodicity, the assumption of a criterion (an axis of rotation), the solidarity, and the multi-tasking must be represented in the human ego, which is responsible for the body it is dwelling in.

Role shift⁶

In our daily lives, we take on different roles depending on our positions. A successful person is the one who recognizes the requirements of each of these roles and, therefore, is able to adjust himself according to these requirements. A person who is a boss at work is not supposed to act like a boss at home. Either a parent role or the spouse role must be recalled. However, the following two mechanisms may prevent such a role shift: the resistance of the ego to change (inertia) and the strong desire of ego to become the axis of rotation for its surroundings.

Axis of rotation

Some of our attitudes imply rejection of any ties to a Supreme Power. This leads to a sub-conscious assumption by which we consider ourselves as the axis of rotation for everything and everybody else. However, the universe is not created according to our selfish comfort; and other people also have their own ego which tempts them to the same sub-conscious assumption by which they may consider themselves as the axis of rotation. It is obvious that in a family or in a society where everybody wants to be the axis of rotation, conflicts will arise, and soon the unity will collapse. A dynamic ego, on the other hand, would recognize a Supreme Power and try to change according to the manners described by Him. Recognition of the Supreme Power also requires introspection and self-criticism according to the criteria explained by that Power. As a result of this introspection and self-criticism, a dynamic ego will apologize for its transgressions, leading to self-change.

Sometimes it is possible to gain by losing

The solidarity embedded in nature represents itself in two main ways. One involves directly helping each other for survival, such as between a mother and her children. The other is by self-sacrificing for others’ survival, such as plants becoming food for animals, and animals becoming food for plants in a cyclical manner, etc. Based on these two solidarities, life on Earth has continued for thousands of years. Similarly, in a healthy relationship, people not only help each other but also self-sacrifice for others. If any of the members of this relationship tries to fix himself/herself as the center and incessantly ask for sacrifice from the other, the relationship collapses sooner or later. An example of such a collapse is the current state of the environment. The excessive and irresponsible actions of human beings towards nature in the recent centuries has led to human comfort at the expense of the strength of life on Earth.

The superheroes: soil, water, fire, air

In terms of multi-tasking, we observe in nature superheroes that do everything but do not get credit: soil, water, fire, air. None of these has an ego. They do not have a conscious mind, either. Somehow, they are working everywhere we see, doing miraculous things. Furthermore, they are obedient to us; we can use them however we want. The coexistence of super-powers and obedience is something that is in complete contradiction to the superhero picture we have in mind.

According to our perception, a superhero can do everything, solve every problem, etc., but most of all, a superhero works alone and has his own rules. Unfortunately, in real life, we hardly observe a superhero that is, say, a good family member or a good teacher who can educate new superheroes. This is because real life and super-powers have opposite requirements: patience vs. speed, self-sacrifice vs. self-realization, giving birth to multitudes vs. remaining as “The Hero.” Without proper education, super-properties will eventually lead to a super-ego that idolizes itself. This type of a character does not make up a healthy personality and is a threat to the survival of the society. From this, it can be deduced that self-improvement and self-realization, if not motivated properly, lead to self-idolization, which is not the way to go for an ego. So, what is the ultimate motive for an ego?

Based on the example of the supers of nature, a suggested statement of the ultimate goal or motive for the ego is being of use as much as, and as best as, possible without gaining credit. However, this statement is not going to satisfy and/or motivate the ego. This is because the ego’s nature requires some “food” for survival. We would not be humans without our egos. So what is the food of the ego? Some people feed their egos with self-satisfaction, which leads to arrogance or pragmatism. Some others choose to take other people’s pleasure as their ego food, which does not work in the long run, since nobody has the power to give all the time without receiving. As a third choice, some people prefer to choose God’s pleasure as a survival for their ego, which looks more promising compared to the other two in terms of self-satisfaction and service to other people.

Challenge in the ego education: Inertia

As human beings, the more we grow, the more we build our own personality/ego and show a sub-conscious resistance to change. This is similar to a train that has already accelerated and which will require a great force to change direction and/or slow down. In another way, it is similar to a piece of brittle solid, like ice, which will break into pieces when hit by a hammer. This solid form of ego is the result of lack of education and sincere love; it eventually becomes a thick, opaque veil in front of the eyes of its carrier, and filters all the warnings coming from outside that point to a need for change⁷ So, how are we going to keep our egos ready for change?

Based on the examples of the train and ice given above, two principles can be seen in order to facilitate the change for ego: obedience and love. The train is subject to the train tracks, therefore it is obedient to the direction shown by the track; it does not go as its inertia requires. Also a piece of ice will not shatter into pieces when hit by a hammer, if that ice is melted⁸ What melts the ego is the heat of love and affection sourcing from the heart. So, to keep our egos ready for changes, we must find a reliable track to obey and the heat of love to melt our egos.

The scenic view

The big picture drawn in this article is based on an alternating motion model with respect to a reliable point of reference. This vision is similar to the rotation of the Earth, both around its own axis and around the sun, which leads to the change of day and night and the alternation of seasons. This continuous change gives birth to the continued existence of life on Earth, where incredible beauties are displayed everyday, every moment. It is up to us to use the free will given by our Designer to preserve the dynamic character of our ego by which we can become the best of creation. It is also our free choice to give in to the inertia that is inherent in it.

The movie makers probably did not intend to make killing look attractive. But was it the final effect anyways? Do movies depicting indecent acts fail to show the consequences sufficiently? What can society do about this trend? These and similar questions have been asked and debated for decades. Below, we analyze a time in Hollywood when the concentrated efforts of concerned individuals and organizations had a significant positive impact on forcing the movie industry to move toward self-regulation.

The Beginning of the Movie Industry

Movies rose as a new form of entertainment at the turn of twentieth century. By the 1920s, 40 million Americans were watching them each week. After winning the right to vote in 1920, flapper girls were exercising their new-found freedom, Harlem nightclubs flourished with whites with an interest in African American culture, and the number of gangs selling liquor during Prohibition increased. Movie producers displayed these value changes in their films to attract more young people. This started the big fight between America’s moral guardians and the movie makers.

Hollywood scandals in the early 1920s accelerated the demand for movie censorship. In 1921, the famous comedian Fatty Arbuckle was accused of raping and murdering a young actress; director William Desmond Taylor was found murdered, and a series of front page stories revealed his drug use and sex life; actor Wallace Reid died of a drug overdose; and America’s “sweetheart,” Mary Pickford, got a quick divorce to marry Douglas Fairbanks.

The motion picture business had become an industry. Film companies seeking to integrate production, distribution, and exhibition had one formula in mind: expansion meant capital, capital meant Wall Street, and Wall Street meant conservative business practices. They could not afford any scandals or federal investigations of Hollywood.

The Pressure for Codes Builds

Leff and Simmons write: “In 1921 alone, solons in thirty-seven states introduced nearly one hundred bills designed to censor motion pictures. Women could not smoke on screen in Kansas but could in Ohio; a pregnant woman could not appear on screen in Pennsylvania but could in New York. Six censorship states, which controlled over thirty percent of the theater seats in America, condemned illegitimacy and sexual deviance.”(1) State censors recut films after the producers, and the outcome was unfavorable. Local exhibitors were tired of the cost of censor cuts and attacks by the public and the media. In January 1922, the movie company presidents formed a trade association, the Motion Picture Producers and Distributers of America (MPPDA). Postmaster General Will Hays, an ex-Republican national chairman with White House connections, was chosen as their head. He was a great success as a spokesperson, but failed as a censor regulator of movie content.

Under Hays, Hollywood instituted a morals clause that, as part of the standard employment contract, regulated performers’ off-screen lives: “The artist agrees to conduct himself with due regard to public conventions and morals and agrees that he will not do or commit any act or thing that will tend to degrade him in society or bring him into public hatred, contempt, scorn or ridicule, or that will tend to shock, insult or offend the community or ridicule public morals or decency or prejudice the producer or the motion picture industry in general.”(2) Furious with such self-regulation and restraints, many ignored the contract, and so the scandals continued.

A mainly Protestant anti-movie lobby grew larger and more threatening in the mid-1920s. The Women’s Christian Temperance Union (WCTU), the Reverand William H. Short’s Motion Picture Research Council, and Canon William Shaefe Chase’s Federal Motion Picture Council, among others, all lobbied for federal action. Supporters of cencorship bills claimed that movies were immoral, vile, and corrupting young people. With the advent of —talking— films, the moral guardians of America faced a bigger threat: movies were more popular and dialogue challenged public norms. According to Black: —In 1928 the New York State censorship board cut over 4,000 scenes from more than 600 films submitted, and Chicago censors sliced more than 600 scenes.—(3) Martin Quigley, owner and publisher of the industry trade journal Exhibitors Herald-World, initiated in 1929 the first attempt by Catholics to influence the film industry. Believing that government censorship was futile, he began thinking of a code that would include rules, regulations, and philosophy. Father FitzGeorge Dinneen, Chicago censor board advisor, sent him to Father Daniel Lord, a St. Louis University professor who could write the document. The resulting production code had three working principles:

• No picture should lower the moral standards of those who see it.

• Law, natural or divine, must not belittled, ridiculed, nor must a sentiment be created against it.

• As far as possible, life should not be misrepresented, at least not in such a way as to place in the mind of youth false values of life.(4)

The production code termed movies entertainment, and those who made them were obligated to produce —correct entertainment— for mass audiences. Movies had a profound impact on the —bodies and souls of human beings,— and could —affect spiritual and moral progress.— Hays saw the code in early 1930. He later wrote: —My eyes nearly popped out when I read it. This was the very thing I had been looking for.—(5) The code announced specific limitations on language and behavior. Lots of offensive words and phrases were banned, and the ridicule of religion, nudity, evocative dances, depiction of illegal drug use, and scenes of childbirth were prohibited. The code was explicit when it came to on-screen crime and sex:

I. Crimes against the Law

These shall never be presented in such a way as to throw sympathy with the crime as against law and justice or to inspire others with a desire for imitation.

1. Murder

1. The technique of murder must be presented in a way that will not inspire imitation
2.  Brutal killings are not to be presented in detail c. Revenge in modern times shall not be justified

2. Methods of crime should not be explicitly presented

1. Theft, robbery, safe cracking, and dynamiting of trains, mines, buildings, etc., should not be detailed in method
2. Arson must be subject to the same safeguards
3. The use of firearms should be restricted to essentials d. Methods of smuggling should not be presented

3. Illegal drug traffic must never be presented a. The use of liquor in American life, when not required by the plot or for proper characterization, will not be shown.

II. Sex

The sanctity of the institution of marriage and the home shall be upheld. Pictures shall not interfere that low forms of sex relationship are the accepted or common thing. 1. Adultery, sometimes necessary plot material, must not be explicitly treated, or justified, or presented attractively. 2. Scenes of Passion a. They should not be introduced when not essential to the plot. b. Excessive and lustful kissing, lustful embraces, suggestive postures and gestures, are not to be shown. c. In general passion should so be treated that these scenes do not simulate the lower and baser element.(6) Interestingly, the above principles set forth by a Catholic scholar were in perfect accord with the moral codes of Islam, another Abrahamic religion that prohibits the vivid depiction of actions not approved by God.(7) By the beginning of the Depression, film studios turned increasingly to themes of sex and violence to attract audiences. Finally, Hays used the resulting public reaction to persuade the studios that enforcing the code would be the most secure and economical answer to their troubles. If the movie industry regulated itself, it could prevent likely government intervention. The film companies were in debt, having spent a lot of money to introduce sound, and many had lost money in the stock market crash of 1929. Desperate to cut costs, they decided to avoid paying to revise the film after the censorship boards made their edits, by following the code before making their movies. The code was adopted in 1930.

Joe Breen Gets Involved

During 1930-34, movie producers ignored and openly mocked the code. The pressure continued from the Catholic Church with the support from Jewish and Protestant leaders. In 1934 Joe Breen, a strict Catholic moralist working as a public relations man for the production code in Hay’s office, was hired to run Hollywood’s Production Code Administration (PCA). Breen brought new standards: —The PCA had the authority to review all movies and demand script changes. Any theater that ran a film without the PCA seal of approval would be fined $25,000.—(8) Finally the Code had some power. Studios accepted it and produced films that met Breen’s standards. Largely because of his efforts to get the code implemented, it has become known as Breen’s Code. It lasted for more than two decades, being officially abandoned only in 1968. Breen’s Code is a perfect example of people affecting the behavior of institutions whose motives may not match the best interests of the people they serve. By expressing their dissatisfaction and organizing to pressure the motion picture industry, Americans managed to change the nature of the movie industry’s products toward higher moral standards held in common by most monotheistic religions. As we go into the twenty-first century, there are many areas in which people of faith can work together to make a positive change in their societies and the world
