On the back cover of the 2017 May-June edition of this magazine we were reminded of the knot that binds us to the tangle we have made of human existence. Releasing the knot, one would contend, requires first an awareness of the nature of the knot, which means knowing what caused the tangle.

We are horribly aware of what is, but hardly aware of why. Your correspondent rather fears to suggest that in respect of human history, and as far as the current terrorists are   concerned, they are not even par for the course. This not an apology and is by no means a suggestion that they are anything less than undesirable, but they do have a long way to go to equal our collective bloody past. You don’t need a list.

It may be reasonable to suggest that frustration is at the root of most human folly. The terrorists are frustrated by their own need to find release from persecution perceived, but more likely a purpose for their lives. It amounts to the adoption of a system, a philosophy, a reason to be. It is often similar, in albeit psychological content, to what we often undertake in the name of “our interests.” Humans are also frustrated by the need for some of us to be rude, as in the appalling attacks of the good name of the Prophet Muhammad, which were used as an excuse to release ingrained frustrations. Should we really be aghast when we end up with a bloody nose after insulting someone? We do not discuss right or wrong because we are confronted by simply what is. Our lack of comprehension when being hit tells of an equal lack of awareness of human decency and that really means our own lack because, after all, you generally get back what you engender. The Hindus call it karma. All right, let’s tell it how it is. “Keep your dirty mouth off me, buddy, or you’re gonna get a smack in the eye.” Thus, however crass, crude or unsophisticated, that is how things stand. We must possibly consider that the human fuse is longer or shorter according to the individual. Even if so inclined, one would perhaps risk an oblique thrust against an educated, worldly wise person, but I will hesitate to walk into a black neighborhood shouting about white supremacy. This by no means supposes that people in a black neighborhood are unsophisticated, but it does suppose common sense, as opposed to being either cowardly or brave, or downright silly. Quite obviously, speaking one’s mind is often far removed from exercising common sense. To be fair, there would seem to be a need for a study about what to do with thoughts that are less than useful. The “freedom to be me” set would protest, but I am suggesting a universal creed, borrowed again from one of the mystics, of being able to do anything you like in this world, as long as you don’t hurt anybody.

Don’t think about it: only God is good.

The peoples of this world have been insulting each other since the beginning of time. Nevertheless, there must be more to the matter. History shows us that most nations have at one time or another been at the top of the pile politically, culturally, and naturally financially. The top nations were then seen to slide right on down again (Rome is the obvious example.) How come? They had it all! It is a common notion to say that wealth brings responsibility with it. But with tons of money available, decadence is a beguiling and easy option. Above all, we are bound to admit that the exhilarating, albeit disastrous, slide down is likely to be made rapid to the extent of a nation’s financial means.

One could also suggest that as far as the terrorists are concerned, they may well be running on a sort of universal “now is my time” program. The wheel of human endeavor has turned – someone has even suggested that there is a noticeable historic cycle in social change – and we are now faced with another bully thrusting to the fore. Please remember that none of the so-called advanced nations have ever succeeded without bullying, usually some other country’s indigenous peoples. This brings about frustration and an arising group urge. First comes the insult perceived, then comes the instinctive, then the planned, fight back.

Please consider that terrorists have, in one guise or another, littered the lives and existence of humans for thousands of years. The name, the cause, the flag under which they kill may have been superficially varied, but the root cause, the why, has always been the same. Humans have an appetite for anger. To be precise, anger is an appetite!

Has anyone ever investigated appetite? The mystics deal with it. The Islamic mystic, Sheikh Jilani, has pinpointed our lower instincts, for which the Arabic word is nafs. Our nafs are not merely our egos, but are somewhat akin to the appetites we attach to our lower impulses. Am I splitting hairs, here? Nevertheless, whether from the Arabic or otherwise, nafs, our lower impulses, are universal one way or another to all of humanity.

The ego is indeed pure until it acquires a less than useful appetite. Our motivating forces (often animal or material in nature) may well be necessary for navigating our daily lives, but there are few among us able to use them under the governance of a human attitude, read God’s guidance. Nevertheless, it may seem to be confusing the issue somewhat to suggest that our lower impulses are also needed to get out of bed in the morning with a purpose. In other words, an ego is little more than a mechanical function that has somehow acquired enormous clout in the minds of humans. The ego is very useful for undertaking work, for getting you to the train on time, for making money, but not for using money for matters of detriment. Such as having a war supported by a war industry. Thus, doing what you truly feel guided to do and nothing else is demonstrably tricky. Your mind will always find a reason for you to indulge in your appetite for sex, drugs and… (ok, let’s keep rock ‘n’ roll), the world, the world. One of the problems arising when discussing ego is that it is loaded with connotation. Everyone will tell you that egoism is bad, but that is not true! It is what you do with your ego that is often out of context. That’s the point, it is the notion of what you do that is of the essence. The big idea, of course, is to keep your self separate from your ego. In other words: my ego, my servant, and not the other way round. Moreover, my mind, my servant, and not the other way round, would suggest relegating the mind to its proper position within the human frame. This perhaps sounds like a good idea, on paper, and one should be able to exercise free will to undertake it. The problem is that not many wills on this earth are actually free. (Ask any parent struggling to put a child through school.) There always appear to be the add-ons, coloration engendered by experience. The Hindu maintains that “…to live life according to experience is the most bitter of ways.” Another mystic has also said that people make most mistakes when feeling happy. That may sound weird, and this writer apologizes for not offering an example. I would need a month on a desert island to figure that one out.

Can we envisage “my mind, my servant”? A mind that serves and does not lead? A humble mind is a rarity, of course. A mind denying its self for most of us would be, well, unthinkable. This writer asks forgiveness for adding sophistry; it is a writer’s test of faith. But it does mean that the true human self should be, but rarely is, separate from a person’s motivating forces. Hence inner conflict.

It has been suggested that to worship God one must make neutral the effects of the heart and the mind. This emptying of worldly influences, which are actually necessary for living in the world, for a period of worship means permitting God to take over. With the heart and mind in neutral, the nafs, our lower motivating forces, are in abeyance. At the finish of worship, the nafs will again thrust to the fore, often with a vengeance. Five times daily in prayer is a constant return to God. Then by the grace of God we may wish to consider the forces within us as they really are. It must be of great value to be able to dissociate ourselves – achieve distance – from our lower forces, get them into focus but not to eradicate them because one may never get off one’s desert island. One may also meditate at lofty Himalayan heights and even “shake” the hand of God, but would be incapable of coming down to the valley where human life goes on.

Our lower motivating forces should be – in fact are – the instruments given at our disposal for work, for undertaking science, for example, for feeding ourselves and our families, thus, for dealing with our worldly responsibilities. Many persons of an ascetic leaning have removed themselves from “the world” in an endeavor to subdue their lower forces. Indeed, Muhammad went to his cave, Jesus went into the desert for forty days and forty nights. Their motivating instinct, however, was submission, for receiving and not conceiving. After all, can we really be wiser than God? These persons then returned to the world to assist the rest of humankind. This writer remembers the story of a Buddhist monk who had received nirvana, after which he returned to the marketplace, the world, to serve humanity. In its simplest form it was all about knowing what makes people suffer, what makes people afraid, what makes people turn to their lower instincts for answers and then makes them fight. The German language offers Existenzangst, which is a good a word as any for describing the root of the human condition.

Jesus returned knowing what makes people be the way they are, Muhammad, too, and he was reported to have cried out in anguish at his knowing. The Buddha came to his realization of what makes people unhappy, which was, of course, desire.

The Islamic tradition leans, quite rightly I believe, on the sciences – the use of the mind to serve for the betterment of human existence. It is not a mystical matter, but it is engendered by a mystical instinct. First the realization, then the serving. Moreover, using the mind to cultivate a garden, harness solar energy, or simply attending to one’s given profession could reasonably be suggested as being God’s preferred way of keeping us out of trouble. Those of theological persuasion may well suggest that one is unable to enter through the gates of heaven through works. This writer would contend, however, that enterprise is not the real meaning of work, or works. It may be reasonable to suggest that anything undertaken through the designs of God has already been blessed, however mundane it may appear. Philosophers, writers in general and those who would delve into higher things are naturally at risk. It is dangerous terrain, often a tightrope walk over a yawning chasm engendered by the heart and the mind, which amounts to the most sophisticated double act to ever enter upon the stage of human endeavor. This writer has also been in the presence of a mystic who once maintained that he had no real knowledge of what he was about to say (lecture notes would be anathema). His inspiration was from above.

Thus, after our daily prayers we return to the world on a hopefully even keel. Our appetites, which, let’s face it, are currently raging around the planet, are for a while governed by a higher force.

It has been suggested – and don’t get me wrong here – that prayer changes nothing. Prayer changes people and people change things. This writer is inclined to equate prayer with a spontaneously arising feeling of hope for betterment in the face of trouble. Thus, to hope for betterment, and not wish to kill, is in itself grace.

The only way to surrender to God, it seems, is to place one’s lower motivating forces in abeyance for a while. But never, ever, try to eradicate them.

This writer finds himself, at long last, reading James Michener’s Iberia. At the beginning of the book Michener tells us about duende (grace recognized) and shibui (aesthetic rightness). Both explanations are approximations. My leaning for such things, my temperament, brought on enthusiasm. The promising beginning was brief, however, and Mr. Michener then takes the reader through 800 pages of small print dealing mostly with the history, art and culture of the Iberian peninsula. Mr. Michener tells us what is or was, but not why.

Andersen KG et al. The proximal origin of SARS-CoV-2. Nature Medicine, March 2020.

Cases of Covid-19 first emerged in December 2019, when a mysterious illness was reported in in the city of Wuhan, China. The cause of the disease was soon confirmed as a new kind of coronavirus, and the infection has since caused a large-scale epidemic and spread to more than 70 other countries. Coronaviruses are a large family of viruses that are related to a broad spectrum of illnesses, the first of which was the 2003 Severe Acute Respiratory Syndrome (SARS) epidemic in China. A second outbreak of severe illnesses began in 2012 in Saudi Arabia with the Middle East Respiratory Syndrome (MERS). On December 31 of 2019, Chinese authorities alerted the World Health Organization of an outbreak of a novel strain of coronavirus named SARS-CoV-2 causing severe illness. As of February 20, 2020, nearly 167,500 Covid-19 cases have been reported, though many milder cases have likely gone undiagnosed. More than 6,600 people have already died as a result of contracting this virus – and the numbers will be much higher when you will be reading this article. Chinese scientists sequenced the genome of SARS-CoV-2 very shortly after the epidemic began and made the data available worldwide. The analyses of genomic sequence data have shown that Chinese authorities rapidly detected the epidemic and that the number of Covid-19 cases have been increasing because of human to human transmission after a single introduction into the human population.

Recently, a group of scientists used this sequencing data to explore the origins of SARS-CoV-2 and how it has become the version that it is now. The scientists specifically focused on the genetic codes for spike proteins, the mechanical framework on the outside of the virus that it uses to grab and penetrate the outer walls of human and animal cells. There are 2 major parts of the spike proteins: the receptor-binding domain (RBD), a molecular hook that grips onto host cells, and the cleavage site, a molecular can opener that allows the virus to crack open and enter host cells. The scientists found that the RBD portion of the SARS-CoV-2 spike proteins mutated to effectively target a molecular feature on the outside of human cells called ACE2, a receptor normally involved in regulating blood pressure. The SARS-CoV-2 spike protein was exceptionally effective at binding to human cells, and the scientists concluded this could only be a product after a natural selection process and not the product of human-designed genetic engineering. This evidence was further strengthened by data on SARS-CoV-2’s backbone molecular structure. If someone were to engineer a new coronavirus as a pathogen, they would have constructed it from the backbone of a virus known to cause illness. But the scientists found that the SARS-CoV-2 backbone differed substantially from those of already known coronaviruses and mostly resembled related viruses found in bats and pangolins. These two features of the virus, the mutations in the RBD portion of the spike protein and its distinct backbone, basically ruled out laboratory manipulation as a potential origin for SARS-CoV-2. Based on their genomic sequencing analysis, scientists came up with two possible scenarios as the most likely origins for SARS-CoV-2.

In the first scenario, the current pathogenic state of SARS-CoV-2 has emerged naturally in non-human hosts such as bats or pangolins and then jumped to humans. Coronaviruses are well known to undergo genetic recombination. In fact, this is exactly how previous coronavirus outbreaks have emerged, with humans contracting the virus after direct exposure to civets (SARS) and camels (MERS). The researchers proposed horseshoe bats as the most likely reservoir for SARS-CoV-2 as it is very similar to a bat coronavirus. There are no documented cases of direct bat-human transmission so far, suggesting that an intermediate host was likely involved between bats and humans.

In this particular scenario, both of the distinctive features of SARS-CoV-2’s spike protein and the cleavage site would have mutated to their current pathogenic state prior to entering humans. In this case, the current epidemic would probably have emerged rapidly as soon as humans were infected, as the virus would have already equipped with the features that make it pathogenic and able to spread between people.

In the second proposed scenario, a non-pathogenic version of the virus jumped from an animal host into humans and after a mutation process it has acquired its current pathogenic state within the human population. For instance, some coronaviruses from pangolins, armadillo-like mammals found in Asia and Africa, have a spike protein very similar to that of SARS-CoV-2. A coronavirus from a pangolin could possibly have been transmitted to a human, either directly or through an intermediary host such as civets or ferrets.

In this scenario, only the cleavage site could have mutated within a human host, possibly via limited undetected circulation in the human population for months or maybe years prior to the beginning of the epidemic. The researchers found that the SARS-CoV-2 cleavage sites have similarities that resemble strains of bird flu that can transmit easily between people. In the case of SARS-CoV-2, such a virulent cleavage site could have been formed in human cells and soon the current epidemic got initiated, as the coronavirus would possibly have become far more capable of spreading between people.

At this point, it is almost impossible to know for sure which of the scenarios is most likely. If the SARS-CoV-2 entered humans in its current pathogenic form from an animal source, it raises the probability of future outbreaks, as the illness-causing strain of the virus could still be circulating in those animal populations and might come back to humans again. It is still noteworthy that a non-pathogenic coronavirus entering the human population and then acquiring properties similar to SARS-CoV-2, the second scenario, is less likely than the first scenario.

In conclusion, this study brings an evidence-based view to the baseless rumors and conspiracy theories that the SARS-CoV-2 was deliberately manufactured in a lab and concludes that the virus has emerged after a natural process that took place in multiple hosts over time. These genetic findings are also consistent with how SARS-CoV2 is currently behaving. The virus has a low fatality rate (1% to 3.4%) and does not seem to act like a bioweapon compared to pathogens such as anthrax or Ebola. Given the previous coronavirus epidemics and the persistence of the culture of eating exotic mammals in China and other parts of the world, the current COVID19 epidemic is unfortunately not a big surprise for scientists and experts. We have to take necessary measures to be more prepared for such outbreaks that may take place in future.

Smart prosthetic hand combines both human and robot control

Zhuang et al. Shared human–robot proportional control of a dexterous myoelectric prosthesis. Nature Machine Intelligence, September 2019.

Holding an object in your hand might seem easy, but it’s actually a very complicated and challenging task; if, for instance, an object starts to slip, you typically have a couple of milliseconds to react. Scientists have been trying new approaches for improved control of robotic hands, particularly for use by amputees. A recent technology was able to combine individual finger control and automation for improved grasping and manipulation by successfully merging the fields of neuroengineering and robotics. This interdisciplinary approach was tested on three amputees and seven non-amputee subjects. The neuroengineers achieved the intended finger movement from muscular activity on the amputee’s stump, allowing for individual finger control of a prosthetic hand, which had never been done before. The robotics team enabled the robotic hand to take hold of objects and maintain contact with them for robust grasping. The amputee first performed a series of hand movements in order to train the algorithm through a machine learning paradigm. This taught the algorithm to decode user intention and translate it into finger movements of the prosthetic hand. Concurrently, sensors placed on the amputee’s stump detected muscular activity, which trained the algorithm to learn which hand movements corresponded to which patterns of muscular activity. Once the user’s intended finger movements were acquired, this information could then be used to control individual fingers on the prosthetic hand. When the user tried to grasp an object, the robotic automation initiated. The algorithm told the prosthetic hand to close its fingers when an object was in contact with sensors on the hand’s surface. This automatic grasping was designed to infer the shape of objects and grasp them based on tactile information alone, without any help of visual signals. The robotic hand has the ability to react within 400 milliseconds, and it is equipped with pressure sensors all along the fingers: it can react and stabilize the object before the brain can actually perceive that the object is slipping. While this promising technology can be used in in several neuro-prosthetic applications such as bionic hand prostheses and brain-to-machine interfaces, there are still many challenges remaining to implement this technology in a commercially available prosthetic hand for amputees. It is currently being tested and improved.

Cats securely bond with people, too

Vitale et al. Attachment bonds between domestic cats and humans. Current Biology, September 2019.

Dogs have long been regarded as man’s best friend. They’re sociable, faithful, and obedient. Cats, on the other hand, are often described as more aloof, mysterious, and independent. But a new study suggests that cats actually bond with their owners in similar ways to how humans and dogs bond with companions. The most established way to study human attachment behavior is to observe an infant’s response to a reunion with their caregiver following a brief absence in a novel environment. When a caregiver returns, secure infants quickly return to relaxed exploration while insecure individuals engage in excessive clinging or avoidance behavior. These tests had been previously run with humans, primates, and dogs; researchers decided to run the same test with cats. 79 kittens and 38 adult cats and their caregivers were recruited. During the test, an adult cat or kitten spent two minutes in a novel room with their caregiver followed by two minutes alone. Then, they had a two-minute reunion. The cats’ responses to seeing their owners again were classified into attachment styles. The results show that cats bond in a way that’s surprisingly similar to infants. In humans, 65% of infants are securely attached to their caregiver and domestic cats and kittens mirrored this, as about 65% of them securely bonded to their people. After the first round of tests, the researchers enrolled half the kittens used in the study in a training and socialization course. The other half served as a control group. Researchers then found the same results, suggesting the training did not have an effect on kittens’ attachment behavior toward their owners. This indicates that once a cat forms a bond, it seems to remain stable over time. This social flexibility may have helped facilitate the success of the species in human homes. It is still not clear what the factors are that shape the caretaker relationship, but it’s likely a miraculous complex mix of genetics, personality, and experience.

An efficient and green way to convert heat into electricity

Zheng et al. Paramagnon drag in high thermoelectric figure of merit Li-doped MnTe. Science Advances, September 2019.

A recent discovery could help scientists to develop more efficient ways to generate electricity from heat that would have been otherwise wasted, such as heat coming from car exhaust, industrial processes, and interplanetary space probes. In principle, magnetic fields can be used to generate electricity. If we move a magnet through a coil or wire, the magnet pushes and pulls electrons that create an electrical current. Magnets themselves don’t have energy, but they can control energy currents through the created magnetic field. The main problem with magnets is that when a magnet is heated up, it loses most of its magnetic properties and becomes a so-called paramagnet. Until this discovery, scientists believed that paramagnets couldn’t be used for generating electricity. In the new study, researchers found a way of designing thermoelectric semiconductors that can convert heat to electricity. The tiny particles in paramagnets, so called paramagnons, ended up producing enough spin to push an electron, for only a billionth of a millionth of a second – apparently long enough to make paramagnets viable energy-harvesters. This breakthrough in the conventional understanding of magnetic properties could lead to more research into how magnets and energy interact to potentially facilitate electricity production from heat that is otherwise wasted and oftentimes harmful to the environment.

Spatial dimensions and unseen reality, important in both science and religion, are areas that have perennially fascinated human beings. The quest for truth, in these and other areas, is best realized when both empirical investigations and divine revelations are wisely utilized. The human race lives in and perceives a three-dimensional world, but the existence of at least one additional (unseen) dimension continues to intrigue humankind. Might not time be a fourth dimension, one that continues alongside the spatial dimensions of height, width, and depth? In terms of relativity, all actions take place not only in the three spatial dimensions but also in the fourth dimension of time; this constitutes the space-time concept.

In 1919, the Polish mathematician Theodor Kaluza (1885-1954) advanced the idea that the universe might have more than three spatial dimensions. He reasoned that there might be a curled-up dimension too small to be seen. Attempts to explain this dimension tend to be convoluted, even when accompanied by illustrations, precisely because it is impossible, in our three-dimensional world, to represent anything in more than three dimensions, even in a sculptured object.

Brian Greene (b. 1963)—a Columbia University physicist, and author of The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory (Norton, 1999)—not only understands this field of physics, but also has contributed immensely to it. His writing concerning string theory, while admittedly controversial and based on a theory in its formative stages, suggests some interesting perspectives that are being considered. Creative speculation, coupled with critical evaluation, lies at the heart of scientific progress. He spends several pages in his bestseller developing an analogy based on a garden hose stretched across a canyon, with an ant crawling upon it. The hose, which appears different to a human with binoculars than to one without them, and also different to the ant, contains a curled-up space that is invisible to all. To imagine oneself successfully inserting a solid book through a solid mirror is to perceive the illusive fourth dimension. An indirect way to approach the complexity of the fourth dimension is to imagine a world of living things that are, like a drawing on a page, only two-dimensional. Those with 3-D capacity would be able to see a two-D world, but those living in two dimensions would be unable to comprehend the three-dimensional counterpart. The extra dimension that Kaluza worked out involved the amalgamation of electromagnetism and relativity.

What do things look like in a super tiny world with ten dimensions? Imagine a picture (displayed in approximations because it represents a six-dimensional shape on a two-dimensional page) in which a drawing of stairways going nowhere is rolled up into a kind of ball of yarn. The ball shape is no accident, for the additional dimensions posited are curled-up, which renders it as difficult to see as the inside of Greene’s hose stretched across a canyon with a crawling ant on the outside. These six-dimensional spaces exist within the three dimensions we know and see and trust. “String theory” maintains that these gigantically-minute vibrating strings, these multi-dimensional voyagers, actually determine the mass of particles and the charge of forces at the subatomic level, which in turn shapes activity in the real world we inhabit. Obviously, string theory is in its infancy, as is the case with all emerging scientific theories. The general pattern has been that theories partially explain truth, and thereby expand the sum of human knowledge. It is crucial to remember that theories are theories, attempts to advance human knowledge. According to this theoretical perspective, the dimensions beyond 3-D are required for the particular resonances rendered by the strings, similar to how musical resonance varies according to violin wood and shape.

Islamic insights into energy-based, higher-dimensional life forms

Since their genesis, humans have relied on religion to explain things which are true, but nonetheless unseen by the inhabitants of a three-dimensional world. Belief in the unseen, or that which cannot be scientifically proven, is a standard element of religious participation. The Qur’an provides many insights regarding the unseen and the effect of the hidden aspects of reality on human lives. First, it links the creation of life forms to water and other earthy elements: “God created every animal from water” (24:45); “… the heavens and the earth were joined together, then We clove them asunder and We got every living thing out of the water …” (21:30).

The Qur’an also affirms the existence of aspects of creation that are beyond the comprehension of humans: “Glory be to Him Who created the components of couples of every kind: of what the ground caused to grow, of themselves (human beings) and of what you do not know” (36:36). Besides indicating that earthy life forms evolved from water and clay (earthy elements), the Holy Qur’an also mentions another type of life form created from “smokeless fire.” There are 117 identified elements on earth and all the earthy life forms evolved from some combination of these elements, with water playing a fundamental role. While elements have been identified, and are scientifically verifiable, we do not know how many forms of energy exist in the universe, but known forms include electrical, radiant, thermal, sound, motion, gravitational, chemical, nuclear, mechanical, solar, geothermal, hydro, fossil, biomass, wind, and natural gas. Moreover, since, each of these classes of energy has multiple subclasses, it is estimated that there are hundreds of kinds of energy. For example, visible light has various wavelengths representing numerous colors, each representing a different kind of energy within the visible light class. Within light there are spectra that are invisible to us, i.e. UV and IR lights that we utilize for our benefits (taking x-rays and for sterilizing various objects).

If “smokeless fire” is interpreted to refer to a class of energy, then the Holy Qur’an seems to suggest the possibility that certain life forms have arisen from energy sources: “And indeed, We created man from sounding clay of altered black smooth mud. And the jinn, We created aforetime from the smokeless flame of fire” (Qur’an Sura 15, verses 26-27; italics added). It stands to reason that our 3-D-limited vision and linear interpretation of time prevents us from seeing life forms that exceed these dimensions, but many people, from many faiths, have insisted that they have felt their influence.

Based on our knowledge of the speed of light (186,000 miles per second), we would assume that an energy-based life form moving at that speed would clearly be invisible to dimension-limited mortals. Humans cannot see any light beyond a limited visible spectrum, but they can sometimes perceive the effects of such light. Persons who hear their cell phones ring would think it ludicrous to dismiss the existence of sound-causing microwaves on the grounds that they are invisible. Nor would they refuse to acknowledge the heating capacity of microwave ovens simply because they cannot visually perceive the tiny waves. Likewise, x-ray photographs, or sunburned skin, give evidence of that which is unseen but nevertheless real. These effects of energy are routinely felt but not seen. Earlier theoretical postulations and examination have led to developments in these known areas of energy forms. Contemporary theories, including string theories, will, hopefully, result in further breakthroughs.

Perspectives on unembodied entities, often called spirits, abound. They range from deep doctrinal perspectives from theologians to the speculative viewpoints of scholars and persons from all walks of life. What these widely divergent views have in common is their belief in the reality of the unseen, and the idea that the unseen may, under certain conditions, be seen. In Zoroastrianism, the evil spirit Angra Mainyu opposes the leading deity, Ahura Mazda. Descriptions of this evil figure have much in common with the devil or Satan (the counterpart of the Islamic jinn, Iblis), who figures prominently in Judaism and Christianity. In Greek mythology, the Daemones are spirits who influence world conditions. Examples of these numerous spirits, and what they bring to humanity, are Algea (pain), Elpis (hope), Eupheme (praise), Momus (criticism), Nemesis (jealousy), and Phobus (fear) (Theo Greek Mythology: Exploring Mythology in Classical Literature and Art, http://www.theoi.com/greek-mythology/personifications.html). In Hinduism and other religions that teach reincarnation, spirits continue to exist through various iterations of life. Hinduism refers to the soul as the Atman, that spiritual entity that precedes birth and continues after death (Bhagavad Gita, chapter 2, http://www.bhagavad-gita.org/).

Mormons, like Muslims, stress the importance of the Prophet Abraham, peace be upon him, and their “Book of Abraham” (derived from an ancient Egyptian papyrus) reveals that spirits exist prior to gaining a body through mortal birth. These spirits “have no beginning; they existed before, they shall have no end, they shall exist after, for they are … eternal” (Abraham 3:38). Likewise, the Holy Qur’an informs to us that God has created all the souls of humankind before He created Adam and made covenants with them: “When your Lord drew forth the Children of Adam – from their loins – their descendants and made them testify concerning themselves, (saying): ‘Am I not your Lord?’ They said: ‘Yes! We so witness!’ Lest you should say on the Day of Judgment: ‘Of this we were unaware!’” (7:172). Referring to unembodied personages still awaiting birth, Abraham states, “Now the Lord had shown unto me, Abraham, the intelligences that were organized before the world was; and among all these there were many of the noble and great ones” (Abraham 3:22). Abraham learned that he was one of these: “And God . . . stood among those that were spirits, and he saw that they were good; and he said unto me: Abraham, thou art one of them; thou wast chosen before thou wast born” (Abraham 3:23). Christian and Jewish beliefs overlap in the Jewish Tanakh and the Christian Old Testament, which include this teaching from the prophet Jeremiah: “Before I [the Lord] formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations” (Jeremiah 1:5). These passages help us understand the views of other religious groups regarding unembodied spirits, a concept that exists prominently, albeit with significant differences, in Islam, which emphasizes jinn.

The Holy Qur’an states that the Creator has made many non-earthy life forms that are energy-based, and capable of changing shape and form. The two life forms described in the Qur’an (in addition to human beings) are angels and jinn. It depicts angels as having originated from light and as lacking free will; they simply obey. It describes the jinn, created from smokeless fire, as preceding the creation of humankind which was made from mud or clay. Both the Qur’an and related Hadith (words and deeds ascribed to the Prophet Muhammad, peace be upon him) identify the jinn as spirit entities capable of appearing in different forms and of acting according to their own free will to assist humans or lead them astray, as well as to worship God or to deny Him. Islam teaches that the jinns can take the form of various 3-D life forms, including birds, dogs, bees, and humans (Ameen, 2005). In an article describing Islamic medical sciences, Speziale (2003) describes the jinn as “created from fire, who inhabit a subtle world in which mankind is immersed, as into a liquid.” This description corresponds well with Kaluza’s string theory as both deal with a multidimensional world, much of which is beyond our limited sensory perceptions. The Qur’an thus portrays the jinns as occupants of a parallel world of spirits, a doctrinal stance that – as shown above – has its counterpart is many other religions.

The jinn are mentioned in more than forty verses in the Qur’an; one chapter is named (Surat-ul-Jinn) explicitly after them. Further information regarding the jinn, their food, behavior, and capabilities come to us through information regarding the Prophet that has been transmitted over the generations via the Hadith. Among the references to the jinns is the following passage from which we may infer that jinns have the ability and responsibility to choose right over wrong: “‘O you tribes of Jinn and humans, did not messengers come to you from amongst you and relate to you My revelations, and warn you of the meeting of this Day?’ They said: ‘Yes, we bear witness upon ourselves;’ and the worldly life deceived them, and they bore witness on themselves that they were rejecters” (Qur’an Sura 6, Verse 130). A second verse reinforces this conclusion: “I did not create the jinns and the humans except to worship Me alone” (51:55).

The validity of string theory relies on the reality of unseen dimensions, and although we do not purport that the Holy Quran directly endorses this theory, it does support a search for truth. Moreover, a number of Qur’anic passages suggest the reality of more dimensions than meet the human eye, and of human inability to comprehend these additional dimensions: “The seven heavens extol His limitless glory, and the earth, and all that they contain; and there is not a single thing but extols His limitless glory and praise: but you [O men] fail to grasp the manner of their glorifying Him!” (Qur’an Sura 17, verse 44; italics added); “Do you not see how God has created seven heavens in full harmony with one another?” (Qur’an Sura 71, Verse 15; italics added).

Can we see jinns?

As inhabitants of a three-dimensional world, we would presumably be able to see a 2-D world, just as we are able to read the two-dimensional words on these magazine pages. Following this logic, those living in a parallel world, with more dimensions than earth’s inhabitants perceive, would have the capacity to observe 3-D activity while remaining invisible to the lower-dimension world. According to such logic, jinns could see humans but not vice-versa. The Holy Qur’an states, “Lo, he [the devilish Iblis] sees you, he and his tribe, from whence you see him not” (Al-Araaf verse 27). Iblis (the counterpart of Satan, Lucifer, the Devil, etc.) is the leader of the evil jinns.

The following verse from the Qur’an, which sounds like a divine approbation of space exploration, has been intriguing to many: “O assembly of Jinns and Men, if you can penetrate regions of the heavens and the earth, then penetrate them! You will not penetrate them save with a Power” (Qur’an Sura 55, verse 33). The Pakistani Islamic scholar Mawdudi asserts that Qur’anic verses describe the capabilities and limitations of the jinn, specifically their ability to travel rapidly though space: “In surah Al-Hijr: 16-18, surah As-Saaffat: 6-10 and surah Al-Mulka: 5, it has been said that although the jinn can ascend to the heavens, they cannot exceed a certain limit; if they try to ascend beyond that limit and try to hear what goes on in the heavens, they are not allowed to do so, and if they eavesdrop they are driven away by meteorites” (The Alim for Windows).

Ghosts and jinns

Western civilization has generally misunderstood Islamic doctrine concerning jinns and has often erroneously equated ghosts with jinns. In Islam, the jinns are real life forms capable of carrying out behaviors and mental processes. Whereas the ghost of Western traditions tends to be the departed spirit of a deceased mortal; Islam has no such concept per se, but maintains that so-called manifestations of ghosts are nothing more than close encounters with jinns. Countless individuals have insisted that they have seen implausible life forms or other objects that appear to have crossed over into the human dimensions to become visible for a time. Many have affirmed that they have seen loved ones, which they explain as the spirit of the deceased, but Islam would tend to interpret such manifestations as evidence of jinns. Some have gone so far as to maintain that such occurrences are explicable via scientific theory, which may be substantiated by evidence. One theoretical explanation is founded on the presence of energy in human life, and in life from other dimensions. Others have maintained that energy appears when supernatural manifestations occur, including cases of so-called hauntings or paranormal activity. Assuming that jinns are made of energy and give off energy, it has been hypothesized that their presence might be measured by electromagnetic force (EMF) detectors, which can examine and record even the smallest fluctuations in electromagnetic fields. According to this line of reasoning, the human body radiates a limited electromagnetic field; electrical appliances – from low-energy light bulbs to higher-energy televisions and computers – give off even more; and jinns, or so-called ghosts, theoretically, would cause far higher levels of measurable electromagnetic distortion. Some have insisted that these distortions are so powerful that they interfere with the working ability of computer systems, EMF detectors, and audio-visual equipment; and that high levels of static electricity have been detected by sophisticated devices. Like string theory, such theoretical suppositions invite investigation, analysis, and refinement in pursuit of truth.

Yet another theoretical approach focuses on recording temperature changes to scientifically detect the presence of invisible entities. This approach maintains that because fluctuations of more than ten degrees have been recorded in small areas with constant temperatures, it is reasonable to conclude that some energy-altering form has been present. Temperature does not change unless something causes such a change. Further theoretical modeling has revolved around cold spots and hot spots, the former linked to the notion that light does not reflect correctly off ghosts, which gives them a dark form because light is absorbed into the ghost. This theory would explain the claim that, even though ghosts absorb both light and heat energy, the general area around them is several degrees cooler than elsewhere in the room. Hot-spot theorists argue that just the opposite occurs; ghosts reflect light and heat rather than absorb it, thus causing the area to be hot or cold.

One of the most common claims of unexplained objects that become temporarily visible involves unidentified flying objects (UFOs). In many accounts, UFO observers report serious EMF distortions, which may result in an engine stalling or car lights ceasing to function. One can speculate that the ability of giant flying objects to maneuver with amazing speed could be due to the presence of jinns, whether for serious or mischievous motives during their brief crossing into the 3-D terrestrial realm.

The Prophet Muhammad’s traditions inform us that the jinns live, take nourishment, have offspring, enjoy life, and die, although their lifespan is unfathomable to 3-D-limited mortals. Like humans, they create different languages, believe in diverse religions, establish varied civilizations, and may choose to be either good or evil. Islamic belief credits jinns with the capacity to terrify humans, carry out pranks, and take possession of their consciousness. Ameen (2005), in his text The Jinn and Human Sickness, describes the type of sickness caused by the jinn, including physical sickness, hallucinations, creating enmity between people, sexual problems, and psychological disorders (52-3). Symptoms of jinn possession have also been categorized and researched by Ameen and include erratic behavior, seizures with no medical cause, paralysis of limbs, frequent headaches, and barrenness in women with no medical cause, Therefore, Islam, as well as other religions, resorts to some form of exorcism – that is, the expulsion of evil spirits from possessed victims. The ability to expel jinn from the human body has been described in Hadithic tradition. Biblical literature also documents the existence of demon possession and the ability to remove such evil spirits from the human body (see specifically the Gospels of Matthew and Mark). Of course, the symptoms of possession are also common problems that plague many humans due simply to aging, accidents, genetic disabilities, or emotional trauma and should not automatically be attributed to jinn possession without careful medical and psychiatric examination.

In summary, we remind our readers that truth is truth, regardless of where it is found, and ultimately all truth is perfectly correlated and logical. Given the sensory and perceptual limitations imposed by three-dimensional mortality, the dazzling possibilities suggested by string theory and other explanations of the unseen prove tantalizing to humans, who are searching to correlate the truths gleaned from various sources, including science and religion. We trust that the summary of string theory, the citations from the Holy Qur’an, the comparative perspectives from other religious traditions, and the overview of some phenomena that seem logically inexplicable, without the insights of revealed theology, will spark interest in the ongoing quest for truth that renders the human experience both fascinating and meaningful.

Figure 1: One of the ways to explain the multiple Dimensions is “String theory.” Theoretical string theory analyses, in hopes of eventually producing a comprehensive “theory of everything,” have focused not only on strings but also on membranes and have inspired new mathematical advances vis-à-vis Calabi-Yau spaces and knots.

Radiation, which refers to emissions of light or particles, is a type of energy transfer. Radiation takes place at any given moment in the environment or the body. Among sources of radiation to which humans are exposed daily are sun rays, radio waves coming from devices such as mobile phones and TV sets, appliances such as ovens or irons that emit heat, and medical machines such as ultrasounds. The radiation emitted from devices and machines do not cause ionization. Ionizing radiation is made up of high-energy wavelengths or particles, and this is the kind of radiation we get from x-ray, CT, and nuclear imaging. This is used to penetrate tissue to reveal the body’s internal organs and structures. Ionizing radiation can damage DNA, and when our cells cannot fully repair the damage, this may result in DNA mutations.[1] The radiation which poses real danger to humans and has the power to ionize is when radioactive—or unstable—atoms decay and emit alpha (α), beta (β), and gamma (γ) rays.

The earth, air, water, and all living things are more or less radioactive because radioactive atoms are everywhere. The average person is annually exposed to radiation levels of 2.6 – 10 mSv (millisievert), which is not that alarming. The maximum limit recommended for people exposed to radiation for occupational reasons is 100 mSv. The lungs of a person who smokes one pack of cigarettes a day are exposed to an annual radiation of 106 mSv.

How can we protect ourselves?

It is recommended by the World Health Organization that children younger than 16 should not use mobile phones; when they do, their calls should not exceed 10 minutes. When purchasing devices, you should also take into account its SAR (Specific Absorption Rate). Prefer devices with a SAR<1 W/kg. It is also recommended to unplug electrical devices when you are not using them, to keep electrical appliances as far away from your head as possible, use the hairdryer for short periods and in intervals, and to avoid using mobile phones for long conversations (or use headphones!).

It’s also worth reconsidering whether using radiation-emitting devices such as mammography, x-rays, or ultrasounds are absolutely necessary. In 2010, the British Department of Health and Social Care banned using tomography for screening purposes. Another study in the US found that one in ten people are exposed to high levels of radiation because of medical tests.

The average radiation rates (mSv) a person was exposed to during use of certain imaging devices is as follows:

Researchers also found that employees in nuclear power plants were exposed to amounts of radiation that far exceeded allowable amounts.

Beware of radon

The natural radiation humans are exposed to most is the gas radon. Some matter with radioactive atoms such as uranium and thorium – both present in the earth since its birth – emit radon, which seeps through the earth and into the walls of houses and through gaps in plumbing. It is recommended to air houses at least 15 minutes every 24 hours as the only way to be protected from radon.

The resistance of living things

Creatures have been created with different forms of resistance to the elements, including radiation. For example, dogs have a lower resistance than humans, while many other creatures such as rabbits, tortoises, and fruit flies have a higher resistance. And then there is the cockroach, which can survive even a nuclear attack. The lethal radiation dose for cockroaches is an incredible 670- 1000 Sv, whereas it is 6-8 Sv for humans.

Scorpions are also much more radiation-resistant than humans. They can withstand up to 1500 Sv, an amount that is 250 times the maximum dose humans can take. Studies have found a correlation between the strength of a scorpion’s venom and their resistance to radiation. The greater the amount of venom, the greater the resistance they have. The presence of the neural transmitter serotonin supports this view.

Are humans radioactive too?

Humans contain trace amounts of radioactive atoms, namely uranium (²³⁸U), potassium (⁴⁰K), and carbon (¹⁴C). An 80 kg human has natural radiation of 8000 becquerel every second, which is equal to 100Bq per kilogram. This amount is not high enough to cause any worry. The human body has 40 trillion cells on average, and every cell has about 100 trillion atoms. The proportion of the radiating atoms in the body is about 8000/4×10²¹.

Precision protection

The radioactive atoms in the body with the highest probability for carcinogenic effects are potassium (⁴⁰K) and carbon (¹⁴C) atoms. The decomposition that leads to cancer stems from mutations in genes, but the molecules that are the building blocks of genes do not have potassium atoms. The likelihood that a cell gets harmed is very low: it is necessary that the particles emitted from the radioactive potassium atom crash into the DNA molecule and harm it, which is as unlikely as threading a needle when blindfolded. The DNA is precisely protected inside the nucleus located at the center of the cell. If we consider the fact that the average diameter of a cell is about 10 microns (1 micron is one-thousandth of a millimeter), we can better appreciate how little space DNA occupies.

Radiocarbon atoms (¹⁴C), on the other hand, might be present in DNA molecules, and they are more dangerous because the emitted particles are more likely to find the target despite having weaker radioactive properties than potassium. A radioactive carbon atom turns into a nitrogen (¹⁴N) atom and may thus cause a chemical change in the DNA. In other words, the carbon atom is possibly to blame for the unexpected development of cancer.

The likelihood of harmful radioactive particles hitting a person’s DNA is low, and the protective system provided for it lowers the likelihood of developing cancer even more. New DNA molecules that form during DNA coupling are repeatedly checked by inspector enzymes. If there is an error, it is detected and then corrected. The broken code is taken out to be replaced with the correct version. Meanwhile, all these steps are checked by other enzymes assigned to the task. More errors might be made in the newly produced DNA molecule because of external factors. Yet ribosomes in the cell start to produce repair enzymes, as per the instructions from the DNA.

When thinking about all the protective factors that have been coded into the DNA for our survival against the 8000 radioactive activities that occur in our body every second, one cannot help but feel awe for the infinite mercy and wisdom that operate in our lives.

We live in a magnificent world inhabited by approximately 8,700,000 species. This number includes only general species, not subspecies. Scientists discover around 2,500 new species every year, and the number is soon estimated to reach 10 million.

All living organisms are blessed with unique bodies, systems, and organs, defense and protection mechanisms to survive and protect themselves, and special features to help them forage for food.

When people get ill due to environmental effects or malnutrition they usually consult a doctor. They try to find a cure by using the medicine prescribed by doctors. However, animals living in the wild don’t have this option. When animals living in nature or on the street get ill what can they do if nobody takes them to a vet? How do millions of species get well and find cures for their ailments?

You might think that animals who become sick in the wild must simply live with their symptoms, but this is not the case. In fact, we have given a clue at the introduction: each organism is equipped with features to lead a self-sustaining life. Either their bodily functions perfectly enable them to live in their habitat or their unique metabolisms protect them from harmful external factors. Animals also can use some plants whose health benefits have only recently been discovered by humans.

In recent decades, there has been a growing interest for herbal products such as walnut leaf, cherry stalk tangerine rind, grenadine red, and celery root to find cure for diseases.

Animals perform amazing tasks with mind-blowing adroitness as if each were an expert chemist. Wondrous mechanisms are activated when a need arises to protect animals from harm.

Some plants with healing properties:

Lupine, quassia, bitter wood, hemlock, fishberry, roselle, henbane, giant fennel root, pistachio, resin, pine turpentine, mistletoe, cumin, hibiscus, hibiscus flower, alkanet, flos elaeagni, camphor, cardamom, St John’s wort, French lavender, Flaxseed, linseed oil, henna tree, quillaia, wall germander, cranberry, aspand, daffodil, water lily, common balm and eucalyptus.

Animals have been consuming and finding cures in these plants since the dawn of time. They are also equipped with many surviving capabilities under extremely severe conditions. Here are a few examples:

Antibiotics expert

With a height of up to five meters, the giraffe is the tallest land animal. Scientists who investigated the scent emitted by the giraffe found 11 separate chemical substances in its fur. The chemicals turned out to have antibiotic properties, having an increased efficiency when combined. Only after a series of experiments can these incredibly complex chemicals be extracted in the laboratory. The giraffe has been using these chemicals to prevent fungi and bacteria, repel ticks, and stop the growth of germs. Where did these tall creatures study chemistry to know how to produce antibiotics such as indole?

The stubborn doctor

The bezoar ibex is a type of mountain goat native to Turkey, Iran, Turkmenistan and Pakistan. It has a motley coat of black, brown, grey, reddish-gold, and white. Both the male and female have horns and a goatee. The name means “cure” in Persian, and the locals must have noticed its habit of eating spurge whenever bitten by a snake. Scientists have identified the substance called euphorbone in the spurge plant. Amazingly, an analysis of this substance reveals that certain chemical reactions triggered by euphorbone neutralize the effects of venom. The poisoned creature looks for splurge from among the vegetation, self-medicates, and treats itself free of charge. It sure is no wonder when one realizes that the goat, the snake, and the plant are all created by the same hand.

The master of diving

Divers who ascend too quickly to the surface run the high risk of experiencing the bends, an intense pain that is likely to kill because of the gasses coming out of the bloodstream. But how do billions of creatures that lack oxygen tubes lead their entire lives in the sea without experiencing the bends?

Dolphins and whales, for example, descend to depths humans can’t reach on their own and then rise like it is no big deal. Human lungs cannot endure the pressure under such depths, but the bronchi and air sacs in the lungs of dolphins, however, are placed inside a protective cover of special cartilage. To avoid suffering the bends, dolphins release all the air in their lungs before diving deep. But how then do they breathe? The answer is hidden in their muscles, or rather in the myoglobin protein that is available in much higher amounts than in humans. These proteins have the ability to hold in high amounts of oxygen molecules. The much needed oxygen is provided from this source, enabling dolphins and whales to dive as deep as possible.

Poison for one, food for another

The macaw is an inhabitant of American tropical regions with an average wing span of 80 cm. It is known to be a tough creature that lives as long as 60 years. The macaw feeds on plants that produce a chemical called strychnine (C₂₁H₂₂N₂O₂), a powerful poison intended to ward off enemies. How can a substance that kills some living things nourish others? Immediately after eating the nutritious but poisonous seeds, the macaw flies to the rocky cliffs in a certain area. When they get there, they gnaw at and swallow some clay-based rock pieces. The fact that the bird ingests clay without any apparent reason is quite an interesting behavior. The reason was revealed only after research into the origins of the behavior. It turns out that the rocks that have clay in them include a substance called kaolinite (Al₂O₃.2SiO₂.2H₂O) that can absorb the poison in the seeds. The macaw can digest the normally poisonous seeds thanks to this absorption and live on with its life safely. There is no way the macaw can know about the substances present in the clay, so how does it know to eat the clay that can eliminate toxins?

The antifreeze expert

The arctic beetle survives against the inhospitable cold of the arctic thanks to a type of alcohol produced in its body that works as antifreeze. The glycerol (C₃H₈O₃), also called glycerin, produced by the insect prevents the blood and other fluid molecules from freezing and thus ice crystals from killing the cells and destroying cellular bonds. Furthermore, the shorter the days and the colder the weather, the more resistant the bodily mechanisms of the arctic beetle become. As the temperature drops, the volume of water in their body is reduced and antifreeze substances such as glycerol and sorbitol are produced in greater amounts. Research on this amazing creature has revealed that it can survive in temperatures as low as -87 degrees Celsius due to glycerol. It is beyond reason to expect an insect to know how to produce an organic compound with the complex formula of C₃H₈O₃ and thus protect itself from extreme cold.

The radiation expert

Scientists analyzed a surviving scorpion after an atomic bomb test, yet they couldn’t find a satisfying answer to how this animal survived the radiation shower that exterminated all other living organisms. Note that scorpions which came into existence millions of years ago are basically living fossils. Thanks to the protective system they are blessed with, in the past they have survived more powerful solar explosions and harmful radiation from outer space and the sun, and handed down these features to future generations.

The creature that never feels cold

The tardigrade, or water bear, is one of the most resistant organisms in nature.

The size of a pinhead, these microorganisms have pin-shaped hoses in their mouth.  These microorganisms have a brain, a pair of eyes, and a digestion system, but they do not have a heart or lungs.  600 different subspecies of the animal have been discovered so far. They feed mostly on moss and lichens and can survive in any environment including space.

They have been observed to survive a temperature of 120 ⁰C and a pressure of 1000 atm. In dry environments they contract, causing the water in their tissues to evaporate. During this process, the oxygen consumption of the tardigrade virtually stops. The wind carries the dried tardigrades to other places and when they find a suitable environment (wet moss or humid places) they can come back to life again.

According to Ingemar Jönsson from Kristianstadt University in Sweden who participated in studies on this organism, it is a mystery how these animals survive even when they are subjected to conditions in outer space.

Animals perform amazing tasks with mind-blowing adroitness as if each were an expert chemist. Wondrous mechanisms are activated when a need arises to protect animals from harm. It is wondrous to see how animals can carry out these complex chemical procedures as if they have been instructed at birth.

How can animals in the wild hunt during the night as if it were day? A remarkable biological feature acts as a pair of “natural” night vision goggles.

Animals can move and even hunt in the pitch-dark of the night. How do these animals see comfortably in the dark? How are their eyes different from ours?

Anatomically, the eye consists of three layers called the Tunica fibrosa (outer layer), the Tunica vasculosa (mid layer), and the Tunica nervosa (retina). The outer layer of the eye is composed of the sclera and cornea; the middle section of choroidea, corpus ciliare, and the iris; and the inner section of the retina.

Light rays reflected off objects first pass through the eye’s translucent layer (the cornea), then into the black round part located in the front of the eye (pupillae, or pupil), and later go through the lenses. The colored section around the pupil, covered by smooth muscles, is in charge of regulating the amount of light entering the eye. The real and inverted image of an object is projected on the retina by the refraction of light through the lens; the image is transmitted to the optical center of the brain as a result of nerve cell stimulation via the optical nerves. Sight happens as a result of these causal chains.

Now, there is a twist to all this: the optical center in the brain accepts spots that do not emit light as black. For humans, this means a loss of sight. Black objects are not visible because they absorb and keep all the light reaching them.

How could these animals, without night vision goggles, see in pitch blackness despite having the same optical mechanisms as humans?

The answer to this question was hidden in an anatomic structure (tapetum lucidum) located in the eyes of some vertebrates. This special structure, lacking in humans, monkeys, squirrels, birds, red kangaroos, and some other mammals, is found in equines, ruminants, and many carnivores. This structure is located in the cytoplasm of the choroidea layers in between the innermost light sensitive ocular layer and sclera, and it acts like a biological reflector. With its crystalline composition of varying colors from golden yellow to white, tapetum lucidum is a wonder of creation. The eyes of these animals shine when a light source is projected due to the aforementioned structure.

The primary task of this formation is to reflect the light which is projected to the rear section of the eye again without absorbing it. This happens due to the crystalline makeup. Thus, lower light levels are enhanced by the repeated reflection in the eye, and sight is enabled for animals. The second job of Tapetum lucidum is to elevate the sensitivity of the retina to light in order to transmit signals with no stimulation strength to the optical center.

This reminds us of night vision goggles. Night vision cameras are electro-optical devices that strengthen the light that is present. Light enters this device through the lens and hits the charged cathode, which has a lot of high energy. The energy load hits the phosphorous screen where the image is focused after passing through the vacuum inside the charger. The image is an enhanced picture on the phosphorous screen and it is not visible directly through the object. Tapetum lucidum however, is such an artistic work that it cannot even be compared with the night vision systems of technology. While the lifespan of a night vision system is only 2,500–4,000 hours (104–167 days), animals with Tapetum lucidum can benefit from this for a lifetime. The newest night vision systems, with a maximum optic range of 30-120 meters, cannot provide sight under light conditions one fourth of the moon’s illumination strength, whereas animals with Tapetum lucidum can see objects hundreds of meters away in much dimmer light.

This isn’t the only example of how masterfully and diverse eyes can be. Damseflies have over 30,000 simple eyes, called ommatids; eagles can see their prey from thousands of feet above them.

By the principle that “certain things are appreciated best in their absence,” if we imagine a dark night in which we are unable to see anything and cannot even step a foot safely, we can perhaps understand that Tapetum lucidum is a great blessing for these animals.

After that question, I found myself at the doctors.

“If your heart is OK, then your body is OK,” she told me with worrying eyes.

“I’ve never had pain in my chest for this long,” I told her. “It feels as if somebody is sitting on my heart. But if I put my hand on my chest, that warmth helps to alleviate the pain.”

She was concerned. We stopped and she urged me to go to the ER immediately.

“I need to pray,” I told her. “It will take ten minutes and I will be at the hospital praying room. There are always a few people there, so don’t worry.”

She nodded. “I believe in the power of the prayer and meditation,” she added. And she ensured that I see a specialist for the chest pain.

I left that building and crossed the road to go to the other building. I was holding my heart, thinking the metaphors that we think of as a mundane saying. None of the metaphorical descriptions were solely poetry or were merely linguistic elaboration. Rather, they all meant what is untold and unseen and indescribable. At that moment I realized this heart was given to me. I was doing my best for a month to satisfy her needs and to ease her tension. But she was behaving as a separate and independent unit that has her own free will. I realized this for the first time in my life. Maybe the metaphor for this case would be extending a helping a hand to my heart, or to surround her with muscles. Maybe I forced too much on her, or did not appreciate the help my individual organs, my body as a whole, have given me.

That night, a friend of mine, not knowing what I had been thinking during the day, told me that we should talk to our bodies. “You should thank your feet that carried you all those years, my friend,” she said. “You should appreciate your eyes, which never gave up on you. You should thank your arms and hands since you would be speechless without them as a writer. You should thank your brain, for she listened to her Owner all these years and served you to be a better human every day.” “You know,” I added, “you are so right. After all, the one who cannot thank people and things cannot thank their Owner, the Beautiful, the Merciful, the Wise, the Choice Maker!”

I have been reading a lot lately. But there is something we learn from life and other people that no book can cover. Thus, I believe humankind is a unique book, its own kind of scripture. Humans read the universe with one eye, and the Scriptures with the other. Thus, we are given double eyes. And humans stand at the conjunction of these two books of meaning, being ourselves the third book which is uniquely because it is not just a book to read but also a reader. The more humans read these two books, the more we become a readable book.

So what is written in me? I suppose the basis of all lines is this sentence I heard from my doctor today: Save your heart, if the heart is good then your body and mind will be healthy. I wish I knew the language of the heart that would make my body healthy and would make my mind a reader and my self a book. The heart is at the center of human life, both in the physical and metaphysical senses. The heart is at the heart of the fact that humankind is a book to be read and discovered. The heart defines what we feel and motivates us in life. The heart defines which way the mind will travel. The heart is the teacher of the mind. Do you think we can unravel the language of the heart?

In the Hebrew Bible, God says to Moses: “I know you by name.” This knowledge indicates a deeper insight as to who Moses really is and tells that the acquaintance via exchange of the names is not just superficial information, but rather a kind of in-depth knowledge.2 In the Psalms, David narrates: “He leads me on right paths for his name’s sake” (Ps 23:3).

Both in the Hebrew Bible and in the tradition of the Prophet Muhammad (hadith), God is present wherever His name is recited: “In every place where I proclaim my name I shall come to you and bless you” (Exod 20:24).

In the Qur’an, in Chapter Baqarah, God declares His intention to create humans. The angels cannot help but ask Him “Are you going to create someone who will shed blood on the earth?” Then God says “I know what you don’t.” When He summoned Adam and asked him to recite the Names He taught Him, the angels were surprised by the knowledge and potential of Adam. “They said: ‘Glory be to You! We possess no knowledge save what You have taught us. Indeed, You alone are All-Knowing, the Wise’.” He said: “O Adam! Inform them of their names.” When he had informed them, God said: “Did I not tell that I know what is unseen in the heavens and on Earth, and I know what you reveal and what you hide?” (Surah al-Baqarah; 31- 33.)

A modern day Muslim scholar, M. Fethullah Gulen, writes that the knowledge given to Adam was not exclusive to him, but rather was given to all humans. Generations of people developed the seeds of knowledge given to Adam and this is how the sciences were developed. Human’s deep desire to know is the seed that was planted in human soul with the “Names.” 3

According to the early 13th century scholar, Fahraddin al-Razi (d. 1209), the knowledge that should be attained first and foremost on earth is the knowledge of God’s names. Only through His names can a person know God.4 20th century scholar Said Nursi (d. 1960) writes that all sciences came from one specific name of God. For instance, 2 plus 2 makes 4, and this relates to equality of the two sides of the equation. Thus, math comes from His name Just, in Arabic, al-‘Adl. Medicine treats an illness and has a strong connection to the name of The Life-Giver, al–Hayy. Similarly, the physics that rule the universe, from gravity to rain, are reflections of God’s name in the language of this world. The clouds function as a sponge, clean the sky, and the rain cleans the earth, leaving behind not only cleanliness but also beauty and tons of benefit for the circle of life. 5

Muslim scholars have written treatises to explain the meaning and function of the Names of God over the centuries. These treatises are called “The Exegesis of God’s Names.” They are manuscripts in libraries, from Spain to Turkey, and in various languages, from Arabic to Turkish. When one considers that Hebrew became a written language in Spain in the 12th century,6 and since God’s names are a theological topic in Judaism, manuscripts on God’s Names in Hebrew might have been penned. I am not aware of any research to disclose the various forms of Hebrew literature on God’s Names. However, there are books in traditional Cabbalist literature on the power of God’s names when recited certain times.7 These types of books also exist in the Islamic tradition, but they are read as a means and formula to pray in the best way to communicate with God. Reciting God’s seven names, though different in Judaism and Islam, exists in both traditions. Certain Muslim scholars used to recite these names, while others recited the other names, either in silence or aloud in a group, once a week, functioning as a social practice of prayer and meditation.

The names of God also formed a genre on its own in poems written by Muslims and Jews. Muslims narrated that the Qur’an reveals a hundred names of God, Allah, being the one that encompass all other names. Yet God’s names are not limited to this number. Another prayer called “Jawshan” enumerated God’s 1000 names poetically.8 This book is narrated in the sources of Shia, yet it is widely read among Sunnis, too. Ali, the son-in-law of Prophet Muhammad, peace be upon him, is known as the door of the city of sciences and knowledge in both Sunni and Shia traditions. Thus, it is not a surprise that Ali narrated this very valuable source on God’s names. After all, God’s names are the keys to opening the doors of knowledge and various sciences till the end of time.

A thousand names of God are poetically narrated in “Jawshan” in a form of prayer for all, 300 names were revealed in the Torah, and another 300 in Bible.9 God’s name reminds believers, not only Muslims of different sects – but also People of the Book, be they Muslim, Jewish, Christian, or someone else – that the hearts and minds of humans address One God, Who has Beauty and Mercy in His Power, and Power and Magnificence in His Beauty.

The answer was interesting and had deep meanings, but still left questions in my mind. The creatures were told: a new species will be created and arrive soon, and each member of this species will be equivalent and worthy of a whole species.

Those who asked the question were silent, suggesting they were satisfied with the answer. But I wondered how a single member of a species can be worth an entire species – and whether destroying a whole species for a new one can really be just.

Here, it was obvious to me that the new species that would be created is humans, and those condemned were the species who went extinct in ancient times, before humanity appeared on earth. This dream vaguely reminded me something that I read in the “Risale-i Nur Collection” by Bediuzzaman Said Nursi.

Bediuzzaman remarkably states that, “A human being is equivalent to a species of other creatures” (Zuhra – 4th point, Isharat al-I’jaz, and Mathnawi al-Nuriya). This line hadn’t really struck me until I had the dream about older creatures questioning this wisdom.

In this dream, those creatures were dinosaurs. I was not scared; they weren’t threatening with their question. They were fighting for their rights and trying to understand the glorious plan, and beyond.

It seemed to me a lovely coincidence that I had a visit to Washington coming up soon and had a chance to visit the National Museum of Natural History, where you can see well preserved remnants of various dinosaurs.

All of the dinosaurs went extinct long before the first human showed up. Dinos first walked on earth over 200 million years ago and dominated the earth until 66 million years ago. Their dominion on earth ended with the Cretaceous–Paleogene extinction. According to fossil records, there were more than 1000 dinosaur species. Dinosaurs had different habits of eating, as some were herbivorous (plant-eating) and others were carnivorous (meat-eating), including fish-eaters and insectivores, and omnivores (including both animals and plants in their diets). We should be thankful that we never knew many of the carnivores like T-Rex, which measured up to 12m (40ft)! It’s obvious that we could not live on earth if T-Rex were still running around. For our arrival, their departure was necessary.

There is no doubt that the human species is very valuable from various aspects, but what puts each person on the same level with another species?

One of humanity’s great merits is our collective understanding. This collective consciousness can be more fully realized through the glasses of faith in God. With the window of faith, humans not only comprehend His speech, but are better attuned to their fellow living beings – and maybe even non-living creatures. Humans are like one who is that all-inclusive and hears all other things. Hence, we can grasp proofs of the most beautiful names of the Creator from the speeches of all creatures.

The light of such understanding in humans leads to an expansion and improvement in our soul. This makes our value high, our sight universal, and our ability to achieve to perfection limitless. On the other hand, many other species are limited in many aspects by their nature, sights, and capacity of perfection. According to religious texts, though humans and other species are valued differently on earth, the divide grows larger in the hereafter. While every human being is re-created with their names, features, matter, and manner, other species return back to the soil.

When you visit nature museum next time, try to listen what the fossils of extinct species tell you about their complaint. They were created for a purpose; they have finished their job and gone. They have done a fantastic job and flourished, while leaving us many petrol reservoirs. Though countless species have gone extinct, more than 1.6 million other species are still living on earth. Death is not an end; nowadays, they are trying to reach out to us and tell us their secrets. We’re expected to become the best fruit of this universe.

This dream made me think about how the ways that Allah could teach us is not limited to what we do when we are awake. Would you ever think that ancient extinct species would also need the lights of the everlasting speech of the All-Wise and All-Powerful, as explained by why a man could be equivalent and worthy of a species of another creature by Bediuzzaman?

Another lesson is that as we live in an oil dependent-century, we are counting on reservoirs that formed millions years ago by the remnants of ancient living beings; but just as we depend on them, ancient extinct species are also counting on us and expecting us to contemplate our purpose for being here, and to show that we’re worthy of being the most glorious fruit in the universe. As the All-wise make things with infinite wisdom, he sends oil to people of this century to help in technology and he also sends further mercy in the form of knowledgeable scholars to answer our questions.
