Among tropical fruits, bananas are probably the most popular, and with good reason. They are delicious and nutritious, and can be consumed by everyone, from babies to seniors.

The banana plant belongs to the Musa genus. The varieties preferred for cultivation are two hybrid species, Musa accuminata and Musa balbisiana. These types are mostly produced in Southeast Asia, Africa, and South and North America.

There are many varieties of banana. Short Cavendish, mid-sized Grand Nines, and longer Chiquita are some of those. The main harvesting occurs in September and October, but bananas can be produced year round in greenhouses.

Bananas are not reproduced by seeds. They reproduce through tissue culture – pieces of tubers or underground shoots. Underground perennial tubers spread horizontally and grow roots. Once the leaves and sheaths inside the annual aerial pseudostem reach a certain number, a flower bud is developed. The flower stalk, rising among the leaf bundles that are in the center of the pseudostem, carries the purple colored flowers that will become fruit.

When these flowers bloom, sounds can be heard. These sounds occur during the tearing of stem when the flowers force away from the crust to form the banana clusters; this is also known as inflorescence. While the buds are quickly developing, the purple leaves open and flowers become visible. Once the flower inflorescence emerges completely, it bends towards the ground. Fruits then form. Since the banana is a parthenocarpic plant, its fruit is generated without pollination from female flowers, like seedless grapes. The approximate time required for flowers to give fruit and become ripe is three months (1).    

Bananas are rich in nutrients. There is 1.1 gr. of protein, only 0.2 gr. of fat, 22 gr. of carbohydrates (fructose, glucose, sucrose and starch, cellulose, pectin), along with minerals like potassium, calcium, iron, phosphate, copper, zinc, and magnesium in 100 grams of a banana. It also contains fruit acids, along with vitamins A, B1, B2, B6, B9, C, D, E and P vitamins. Before bananas ripen, when they are still green, they contain approximately 1% sugar and 20% starch. As they ripen, the sugar content rises to 20% and the starch level drops to 1%.  

Bananas are harvested green and unripe and are matured in a closed environment. Unripe bananas can be stored for up to 15 days at 5-10 degree Celsius and 80-90% relative humidity. Maturation is enabled via ethylene gas, in storage rooms or during shipment. The shell becomes completely yellow, with brown spots, when the banana ripens. These spots indicate the sufficient conversion of starches into sugars. It is recommended to consume the ripe fruit as soon as possible.

In the past, the transportation of mature fruits to remote regions was a major problem, but this is not the case today. It is because methylcyclopropene (MCP) is used to delay the ripening of the fruit. When MCP is used, it binds to ethylene receptors, and slows down maturation (2). The proper storage temperature is 13-15 degrees (Celsius), so they get darker in the fridge faster. Therefore, it is advised to store them in a suitable place in a paper bag (3).

Even though they are usually eaten raw, as a fruit, some banana types are consumed after cooking. They can also be utilized as chips, baby food, puree, flour, or juice. In some places, banana flowers are used in salads and as decoration. Furthermore, bananas are employed in facial and skin care products. The leaves and stalks of the banana plant may also be used in the construction of roofs, and the fibers can be used as ropes, upholsteries, or even hats.  

According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), the annual production was 55-60 million tons in 1995, whereas it is 90-100 million tons today. 25% of the production occurs in India, and the majority of the rest takes place in the Philippines, China, Brazil, and Ecuador. Even though they are grown in various parts of the world and traded widely, bananas are mostly imported by developed countries.

Benefits of the banana

Bananas can help prevent many diseases or provide complementary aid to different therapies. When a banana is blended with milk, it can serve as an ideal starter food for babies, and can also reduce wear and tear on the body, delaying aging.

Bananas have been shown to help after stomach or intestinal bleeding, and in patients with ulcers or various laryngeal problems. They can help prevent acid reflux. The sodium and potassium contained in bananas are effective for restoring heart beat rhythms and the body’s osmotic balance. Since bananas are rich in iron, they’re beneficial for anemia. Due to a high amount of serotonin, bananas can actually make people happier, improving our decision making and concentration. Because they can actually make us less depressed, bananas are a recommended snack (5).

Bananas help support the development of children’s skeletal structures, and can ease the pain of menstrual cramps. Aside from being an energy source, bananas help the nervous system function properly, maintaining the acid-base balance of bodily fluids and strengthening the immune system. Because of high magnesium and potassium, they help us sleep better – thus making a banana the perfect midnight snack!

Carbohydrates can cause instant blood sugar spikes, but they are also the most important energy source of the brain, central nervous system, and muscles. When blood sugar rises, it is stored as sugar or fat with the help of insulin secreted by the pancreas. This can cause obesity, or even diabetes, if a person ingests too many carbohydrates. Therefore, one must consume high sugar foods like bananas at the right time, and in the right amount.

Beta-carotene, one of the precursors of vitamin A, happens to be abundant in bananas. Beta-carotene helps with the neutralization of free radicals, supports the immune system, prevents cardio-vascular disease, and is protective against cancer. It’s more beneficial when taken together with vitamin E and C, which are also found in bananas.

The good news keeps coming! Due to a high amount of fiber, bananas are great for dieting and can also prevent colon and bowel cancers. Bananas can also help to regulate bowel functions.

Genetically modified banana plants are also employed for the synthesis of vaccine proteins used against Hepatitis, rabies, dysentery, cholera and other intestinal infections (7).

As you can see, the banana has been imbued with an extraordinary amount of positive properties. It’s not difficult to look at bananas as an amazing blessing bestowed upon humanity.

My leaves reflected the moonlight. I looked up at the moon, and it looked back at me brightly. But even its lights seemed somehow unfamiliar to me.

I slowly turned my flower head to the right to watch my brothers and sisters. They all looked pretty exhausted from the long journey, and in their face I saw the same concerns as mine. They, too, felt like strangers here.

Feeling a little bit depressed, I sighed and just wanted to sleep, but in this precise moment a move in the dark bushes that separated the garden from the fence attracted my attention. I caught sight of a small hyacinth. She looked at me curiously, as I smiled at her with mild exertion.

My smile was returned immediately, and visibly excited she gave a sign to those behind her. All of a sudden, there appeared a bevy of hyacinths, closely followed by – I could not recognize them right away – small carnations and roses.

Chatting and giggling, they hopped over to me and I realized that they were thrilled. A small carnation stumbled while running and fell to the ground. The hyacinth, which I saw first, ran back to her and helped her up.

The flower children surrounded me, eyeing me curiously. I smiled back at them kindly, a little nervous. Unexpectedly, they all erupted into laughter. I hadn’t seen such vivid flower children for a long time.

The hyacinth took the little carnation that had stumbled by the hand and started to speak:

“You and your siblings did arrive just now, didn’t you?”

I nodded, hoping that she was old enough to guess that I simply wanted to have my peace and quiet. But unfortunately, she apparently wasn’t… None of these little children were.

A murmur went through the swarm of children.

“Wow! Then you are a tulip, aren’t you? We have heard of you tulips. You guys are the first tulips coming from there,” said the hyacinth, pointing east. Her big eyes were shining with enthusiasm.

Yes, the East. From there, I came here; from a land where the sun rose and sometimes only reluctantly went down again.

My petals cramped. It had been very painful to leave that wonderful place, my home and my people.

As if reading my gloomy thoughts, the hyacinth said:

“It’s really beautiful here in the West! God showers us with water and it is pleasantly cool, sometimes even colder than we would like. Besides, we are well treated. The people are really fond of us.”

These words reminded me of the magnificent brightly lit tulip festivals, which used to be celebrated in the Ottoman Empire, of the nights made into days, and of the wonderful names we have been given, like face of the beloved or lucky star. At once I felt warm all over my carpels.

But once again, grief seized my flower head, and my sepals sank slightly due to their oppressive severity. “How long are you here, now?” I asked the kids, only to divert my attention from these thoughts.

The hyacinth shrugged her leaves:

“I don’t know exactly, but I think it was my great-grandparents, who were brought here.” The other flower children nodded doubtfully. They didn’t know anymore.

“Do you actually know anything of the country from which you, and…” – I briefly swallowed – ” … I originated?” They shook their heads. They were so young, so inexperienced. I smiled and sighed acquiescently, because I had to suppress my fatigue.

“Would you love to learn something about your country from me?” I asked.

The hyacinth politely set me straight:

“Here is our homeland. Here we were born, and here we are living in peace and joy with each other. I know my homeland. But I would pretty much like to hear something about the country where you and our great-grandparents come from.”

Smiling back at her, I was slightly confused about this answer. She was very smart, for sure, and would be a wise flower.

“Well, then sit down. I want to tell you about my homeland that is also the land of your ancestors.” They bounced close, and formed a semicircle around me with their eyes curiously focused on me.

“I am a tulip and I used to live and prosper in the Ottoman Empire, where I was surrounded with every imaginable flower. The Turks love us so much so that we have become an important part of their art and literature.”

Again a murmur was heard, and I had to smile about the naive way of these children. My fatigue and my gloomy mood slowly vanished. It was nice to relive those memories again.

“I don’t want to dive too deep into this topic. But we all are common motifs of the so-called Quatre-Fleur style of the Ottomans in the crafts.” It still made me very proud when I thought of it.

The hyacinth intervened:

“In this country, people say that we flowers have our own language. Each of us has a very special meaning for them and is given away as a present on certain occasions.”

I looked at her in surprise and let her continue. It sounded exciting.

“And not only have the flowers special meanings, but their colors as well.” The children in the semicircle nodded in agreement. “Tulips, for example, symbolize love and affection. Lovers present each other red tulips. Orange symbolizes fascination and blue means a promise of fidelity.”

My stamens trembled with joy when I heard that. How beautiful, indeed!

“This brings me back to the Ottomans,” I smiled at the children. “They also have something like a language of flowers, but somehow different from yours. They, for example, place yellow roses on the window sill, which is saying something like: there are sick or old people living in this house. In this way, passersby were prompted to behave quietly, which they did.”

I gave the flower children a short while to digest this new information, which apparently pleased them.

“By the way, do you actually know where I originally come from?” I asked them. They shook their heads. “My ancestors once left their home as well and were brought into the Ottoman Empire.”

The astonished hyacinth interrupted me:

“Does that mean that this isn’t the first migration?”

I gave her a nod. “Your ancestors were not the first, and I certainly won’t be the last who moves from one place to another in this wide world. There have always been trade relations between nations, and this will certainly remain so.”

The children smiled at me.

“And from where did you come to the Ottoman Empire?” the little carnation asked me timidly.

“Well, my real home … We tulips were already mentioned by the Greek writer Xenophon, who lived from 430 to 354 BC. And in the fourteenth century the Persian poet Hafez introduced my species into literature. He called us Lale, and this name so much appealed to the Ottomans that they adopted it.”

“In Turkish garden culture we had our heyday with Sultan Ahmet III. At that time, a whole era was named after us: The Tulip Era – Lale devri, which began in 1718. The tulip hype exceeded all bounds. There were 1323 different varieties.”

“Do they only have tulips over there?”

I shook my flower head. “No. The Ottomans had many flowers, including hyacinths as well. A part of the courtyard gardens of the Sultan were always reserved for you, the hyacinths; and this is still the case today.”

The hyacinths giggled again and whispered to each other. “See, I told you,” the first hyacinth whispered to the others.

“The poet Fazli, an Ottoman poet, often wove the hyacinth motif into his poems,” I continued. “And in Edirne and Istanbul, there are meadows covered with fragrant hyacinths.”

“Do you also know where we came to the Ottomans from?” another hyacinth, tall but very thin, asked.

“From the gardens of Baghdad and Aleppo,” I told her. A murmur rose again. The crowd of children thoroughly enjoyed themselves.

“How exciting,” they blurted.

Thus I added, “by the way, you folks came to Europe in the sixteenth century.” While they kept on jabbering with each other, the little pink carnation looked at me expectantly. Then she squeaked hesitant and softly:

“Have you also got flowers like me in the Ottoman Empire?”

I smiled at her. “Carnations, you mean?”

She nodded eagerly, and her cute petals shook with her head.

“Of course, even at the time of Theophrastus, in 300 BC, you were already growing. But I guess it was the Arabs who brought you to the Ottomans. At least, you got your name from them. The Arabs call you Qaranful, which is probably derived from the Latin Caryophyllus or from the Greek Karyphillon. And the Ottomans call you Karanfil.”

The eyes of the flower children widened and they tried to repeat the name slowly. Apparently they liked it very much.

For the first time, a small rose spoke up, slowly and gracefully as is to be expected from a rose:

“And what about us? What did we mean to the Ottomans?”

Again, I had to smile. What a question!

“Roses are sacred to all Muslims and, therefore, also to the Ottomans. They play a major role in Turkish culture.” The roses looked at me in surprise. “The Ottomans never left rose petals lying on the floor because rose in their tradition symbolized the Prophet Muhammad, peace be upon him.”

“Wow,” the children whispered reverently, as with one voice. The carnations and hyacinths respectfully looked up at the roses. They, in turn, humbly looked at me, waiting for me to go on, which I did:

Again, the flower children were whispering to each other. At the sight of them, I rejoiced. Now, they were my new neighbors. What luck! With them, I would certainly never get bored.

I looked over at my tulip siblings. They had already made themselves comfortable and were sound asleep. Out of the blue, I felt tired again. “Dear children! Tomorrow I’ll tell you more, if you want. But for today, it’s enough.”

A disappointed murmur rose. But the hyacinth encouraged me.

“Okay friends. She’s right. It’s enough for today. We should go back. Our parents are probably already worried. It’s getting late.”

“But I certainly would like to know more about my ancestors in Albania,” the little carnation complained.

“Arabia! Your ancestors came from Arabia! Just listen more carefully,” the hyacinth chastened her. She stood up and pulled the others behind her. “And now let’s go home!”

“Didn’t you forget something”, the hyacinth asked the flower children. As if on command they all turned again to me and shouted:

“Thank you very much, Mrs. Tulip!”

I laughed. The hyacinth had a very good grip on them.

“You are welcome,” I replied. “Good night!”

“Good night,” they echoed back, and with a broad grin and still fidgety, they retreated. I was alone again, and at once felt a little lonely. So I hurried back to my brothers and sisters.

This country seemed to be very exciting, at least more exciting than I would have thought. I smiled and suddenly did not even remember why it seemed so strange to me in the beginning.

In recent years scientists have taken huge steps towards the bio-hybrid architecture developed for exploring an alternate approach to the control of autonomous robots (1). The plant-robot interactions through cyborg plants have been investigated in an effort to apply lessons from plants to robots, which provided another role for these organisms other than being a food source or decoration items. There are several joint experimental, numerical and robotic studies conducted in this newly developed area. One of the examples includes a flower robot made by Korean engineers which has the appearance of a common flower with petals, stem and leaves (2). The flower robot has sensing ability, moving mechanism, and home appliance function. It can recognize environmental conditions such as room temperature, pressure, voice and light intensity and can imitate the blooming of a flower, the bending of the stem and the stirring of the leaves in the wind. Other than these, the flower robot functions as a humidifier, a vision/voice recording system and an illumination device. For example, when flower robot receives light, it senses the intensity of the light and blooms. On the contrary, when it is dark, as the flower robot starts fading away and its illumination device turns on to flash the room.

Plantas nomadas, made by Mexican artist Gilberto Espaza, is another example of cyborg plants. It uses dirty water to live. It is a miniature eco-system consisting of plants and micro-organisms within a robotic shell. Each of the components symbiotically relies on the others: the plant provides the perfect environment for the microbe, and the microbe (in a microbial fuel cell) transforms nutrients in dirty water into energy to power the robotic components, and the robotic components provide mobility (3).

A team from Switzerland has been working on a project that endows a robot with the ability to react in response to environmental stress of a plant in order to maintain the state of the plant. The robotic devices monitor the changes in morphology and electrical activity of the avocado plants. According to these parameters, it classifies the drought level and triggers irrigation when necessary (4).

Some of the artists like James Stone, who is a Media Artist specializing in digital technologies and fabrication, are interested in seeing if plants are prone to act in certain ways, show preference and possibly display other traits such as emotion. Artists are specifically curious as to what would happen when a plant is augmented with technology but also given full control over such technology to do with it whatever it chooses (5). To see the results of such systems that provides a means for the plant to interact with people or things will surely be fascinating. A study in this line of research is done by a group of researchers in mobile robotics at ETH Zürich, whose long-term research goal is also to bestow machines with the ability to gain and employ knowledge from the universe to improve their intelligence, by building a prototype called iRobot Create. This cyborg plant consists of a computer running Linux, a normal plant and additional sensors and lives its own life, following its internal needs of water, sunlight and electrical energy (6). The cyborg stays away from obstacles using ultrasonic sensors, finds the best light spot using light sensors and goes to a recharge and to a mock-up water station using iRobot’s infrared sensor. Moreover, its sensors pick up noise caused by people moving around nearby, allowing cyborg plant to react by moving out of the way, to prevent themselves from getting underfoot (7).

It is very important to improve the ability of robots to work successfully in a complex and harsh environment, which would increase their usages. In one of those efforts exploring the use of biological systems to control robots under changing environmental conditions, Dr. David Hu and his group from Georgia Institute of Technology (8) used the Mexican jumping bean, Laspeyresia saltitans, which consists of an empty seed housing a moth larva. Heating by the sun stimulates movements by the larva which rolls, jumps and flips by the bean. They explored this unique means of rolling locomotion and recorded bean trajectories across a series of terrain types, including one-dimensional channels and planar surfaces of varying inclination by Time-lapse videography. They found that the shell encumbers the larva’s locomotion, decreasing its speed on flat surfaces by three-fold. Interestingly, they also showed that the two-dimensional search algorithm of the bean resembles the run-and-tumble search of bacteria. When they tested this search algorithm using both an agent-based simulation and a wheeled Scribbler robot, they demonstrated that the algorithm succeeds in propelling the robot away from regions of high temperature. It is amazing that from a study that involves a plant seed, a moth larva and a robot, scientists may develop applications in biomimetic micro-scale navigation systems.

The hi-tech devices that have been inspired by biological systems are not limited by the ones stimulated with plants. The insect world also represents a huge and original database for future bio-inspired systems, vehicles, and micro-vehicles (9). For example, the process of motion detection system in the fly’s eye is a good example of a neural circuit that was used for robot automatic piloting. Recently, a novel bat-like unmanned aerial vehicle inspired by the morphing-wing mechanism of bats has been presented (10). Other than that, body undulation used by snakes and the physical structure of the body of a snake may offer major advantages over typical legged or wheeled locomotion designs in certain types of scenarios, therefore a large number of research groups have developed snake-inspired robots to make use of these benefits (11). Caenorhabditis elegans, a roundworm which has similar motions with snakes but with a simpler structure, was also selected to develop a small crawling robot with a thermal shape memory alloy, a homogeneous mixture or solid solution of two or more metal, as an actuator (a type of motor for moving or controlling a mechanism or system) due to the similarities of its properties to C. elegans muscles. (12).

Not only multicellular organisms but also unicellular (single-celled) organisms are utilized for generating cyborgs; for example, scientists used circuits prepared from Physarum polycephalum, amoeboid plasmodia of the slime mold, to control an omni-directional hexapod robot. Sensory signals from the macro-physical environment of the robot are transduced to cellular scale and processed using the unique micro-physical characteristics of intracellular information processing and the response from the cellular computation is amplified to yield a macroscopic output action in the environment mediated through the robot’s actuators(1).

In addition, a new biorobotic system using human neuroblastoma cultures was introduced in 2011 by a Spanish engineering group (13). Multielectrode Arrays Setups have been designed for direct culturing neural cells over silicon or glass substrates. The main objective of this work is to run a robot using this biological neuroprocessor and the final system could be used for many things such as testing how chemicals influence the behavior of the robot.

In summary, manipulation of robots that use living organisms as an interface to perceive the environment and transfer their responses into functions seem to have endless applications as well as challenges. Biologically-inspired technologies represent an emerging and promising field of interdisciplinary areas composed of engineering, computer sciences, chemistry, biology, physics and even art. In nature there are so many living and non-living elements designed by God to help us develop and improve robots to make our lives easier, better and more productive. Even a flower can offer us with something more than color and scent, and that is if we start thinking outside the box like so many people mentioned above have done.

Bent down in prayer as winds blow by.

No glimpse of greed or poverty,

Once again she stretches up beneath the sky.

Listen closely to the flower’s song,

As pedals play their part.

To turn Man’s eye for a moment long,

To God’s great work of art.

“See order in my rhythm,

See plan in my design.

See prayer in my precision.

’I’ve been sent here as a sign.

Ponder now, before I’m gone,

For winter here draws nigh.

Without knowledge of why we’re here,

Is not wisdom naught but a lie?

And as I sing my final song,

This is what we all will learn.

To God it is we all belong,

And to Him is our return.”

It was around dawn, and the day was not yet fully light. Rain the night before had left a thick cloud covering the scene. The music of bugs and the chanting of birds filled the air. Against a background of a slight breeze, which provided a smooth and continuous whistle, consecutive, rhythmic thumps could be heard. These thumps were the sounds of a giant’s footsteps as he was walking to work early in the morning.

Meanwhile, my grandpa and his friends were enjoying the water on the walkway. But a hot day was soon going to make the walkway the death bed of many of his friends. Aside from the heat of the day, the footsteps of the giants would bring to an end the lives of many others. Neither he nor his friends were aware of any of this. They were simply enjoying their water on the walkway.

That morning, the giant who was walking to work bent down towards my grandfather, grabbed a thin stick from the ground, and tried to kill him. Not ready for such an attack in the midst of his breakfast, my grandfather was stupefied, did not know what to do. He just spiraled away to escape the giant’s attack, as we always do in case of danger. But all was in vain; the giant would not give up.

Finally, the giant accomplished what he was trying to do, and thus my grandfather was saved from both the heat and the giant footsteps. It turned out that my grandpa had misunderstood the giant. Normally, other giants would walk on us, or would ignore us, and this giant was the same; or so he had thought. However, this one was trying to put the stick under my grandpa to lift him and place him onto the soil where he could be safe. My grandpa said that he appreciated this help more later when he heard his friends dying on that same walkway.

The story of a giant who was unlike others spread from the family to friends, and became known all around. The world underground rejoiced at the existence of this one giant who was not like others… Maybe there were other giants like him, too; and the underground world kept praying for those giants that they might be protected from things they were unaware of, just as that giant had saved my grandfather from things that he was unaware of.

After my grandfather’s times, his story became a nostalgic tale for the elders and a bedtime story for little ones. The world aboveground became worse than the world underground. Instead of long trees above with their roots under ground, you would see huge, tall rocks in both places. The rocks underground provided water to everyone, but the rocks aboveground only provided water to the giants. The roots of the plants and trees used the marrow of the earth to embellish it, but the long channels that the giants sank into the ground were like huge veins draining the earth to death. We ceased praying for them.

One day, we heard screaming among the giants about an asteroid heading directly towards the earth. The only thing they were worried about was the end of their own lives. We were not surprised by this selfish reaction to that event because of their selfish past on the earth. And the asteroid came…

It was foggy again, but not due to clouds; it was quite dark, but not due to dawn. The fog and the darkness were due to dust spread over the face of the earth. We were fortunate to be able to sustain our lives under such harsh conditions. As for the giants, they were not suffering much from the conditions, as they had taken shelter in special chambers built only for them. Being some of the few survivors of the impact, we were of significant use to them. After using the entire earth selfishly, now they were enslaving us. So, they still lacked our prayers for their protection. Could they ever figure out, despite their hardened hearts, why such tragedy had befallen them?

Not long after that time, we witnessed something totally incredible. One of the giants came out of the protection chambers to do something that was completely unexpected. He looked through his goggles at the sky and tried to take a deep breath. As he was coughing because of the dust in the air, he opened the nylon bag he was carrying. He sat on the ground, dug a hole with his hands, and uncovered the thing in the bag: a daisy plant. Was he going to plant it? But why? The chances of its survival were almost none. What benefit would it bring him, anyway, even if it survived for a day? He looked pleased with what he was doing. He even smiled at a worm that was escaping the hole he had dug for the flower. What was going on in his mind?

It was just at the moment he was about to plant the flower that the earth suddenly started shaking like crazy. The planet was dying because of the deep cracks caused by the impact of the asteroid. Now, neither the giant nor the flower had any chance of survival. He did not know what to do for a while; then he started shedding tears: “Oh my God! Oh my God!”

Then he saw the deep cracks forming near him, shaking and growing. It was as if the planet had started shouting at him in thousands of voices. He could not stand the quakes and fell down next to the hole, as if it were he, instead of the flower, that was going to be buried in it. At that moment, this giant was no different from us: lying on the ground, and seeking his way out of this doom. Who was there to help him? His cries were now screams: “Oh my God! Oh my God!”

All of a sudden, he stopped crying and started talking to someone, but we could not see anybody around: “Please, hold me tight. Do not leave me….” He continued, “But I can’t… I can’t….” Then, he tried to reach the flower that had rolled away from him when he fell down. He grabbed it and cradled it at his chest; but struck by a stone falling from one of the nearby rocks, he fell unconscious. As he was sinking into the growing cracks, we uttered a prayer for a giant who had planted a flower in his heart… The last prayer of worms, the last prayer for giants…

Many important characteristics exist in seeds. Seeds are equipped with all the necessary information about the branches and leaves of the plant which they will become, as well as the number and shape of these leaves. Within the seed is programmed the color, fineness or thickness of the bark, the number and width of the tubes that carry food and water, whether the plant will bear fruit or not, and if it bears fruit, the taste, smell, shape and color of this fruit. Even information about how the plant will react to a negative condition in the environment during normal development is registered in this program. For example, a plant that would normally develop under ideal climatic conditions is programmed to produce seeds in a short term to protect reproduction under unsuitable conditions like drought and great heat. God is He Who splits the seed-grain and the fruit-stone (so that they germinate by His command). He brings forth the living from the dead, and He is One Who brings forth the dead from the living; such is God: how then are you turned away from the truth and make false claims? (An’am 6:95)

If we consider the growth process of the plant from a seed that is equipped with perfect information, we can see that once the appropriate conditions have been created the seed first germinates and then the body and leaves are formed on this stem. When the time is right, flowers form in keeping with the divine order. The flowers that later form the fruit and seeds for further plants are either brought together with their own pollen (cleistogamy or self-pollenization) or with other pollen from another plant of the same type (cross-pollination) in a perfectly organized system. Self-pollenization occurs either before the flower opens or after the pollen has developed. Because the pistil and stamens of some plants are hidden by some other parts of the plant, it is difficult for the pollen to reach here, so the plant obeys what is ordered and self-pollinates.

In cross-pollination, plants use the pollen from another plant of their own species. Pollen transportation occurs with the help of the wind, rain or insects that visit flowers.

The flowers of many plants that are pollinated by the wind and rain are very modest in appearance, but they have been created in a way to produce pollen in abundance. Although most of the pollen that is carried away by the wind and rain are destroyed, this lost pollen organically enriches the soil and at least some of this pollen will find a flower to pollinate. Our Lord has bestowed those flowers that are pollinated by insects with various colors and shapes to attract these visitors. During pollination, the pollen of flowers that have less pollen than the self-pollinating flowers are carried by bees and other insects, whose legs, wings, and antennae have been created specifically for this task, as they have been inspired (Nahl 16:68–69). Nectar and pollen are the reward for these insects which provide pollination.

Bees are the most important group among the insects that carry out the task of pollination. When bees are mentioned, most people think of the honeybee, but bumblebees also serve mankind. In addition to the products they offer to us, bees are indispensable for their contributions to plant reproduction.

Bees store the nectar they have sucked from the flowers in a “honey stomach” and then empty this nectar into a honeycomb as honey. The bees legs, granted to them by the Creator, allows them in their duty of collecting pollen. The back legs of the bees are different from that of all other insects. The long hairs that are aligned on these stocky legs act almost like a basket to collect the pollen.

Of the 82 plant types that meet 90% of the human food needs around the world, 63 (77%) are pollinated by bees; without bees it would be impossible for these plants to produce seed. Bees are absolutely necessary for the formation of seeds in plants that we eat, like apples, pears, peaches, apricots, cherries, melons, watermelons or pumpkins, or indeed in those used in industry, like sunflowers, safflowers, rapeseed, cotton, or sugar beets, or those used for feeding livestock, like clover, sainfoin, red clover, or vetch. This task carried out by bee pollination every year throughout the world is much more important than the production of honey. Moreover, bees make life possible for animals from thousands of species who use these plants as food or shelter. We should not forget the connection Einstein drew between the disappearance of the bees from the ecosystem and Doomsday.

Another vital mission entrusted to bees is the prevention of erosion. Plants that need the pollination of bees, like members of the Asteraceae, Boraginaceae, Brassicaceae, Campanulaceae, Compositae and Fabaceae families, are widespread in areas were there are serious threats of erosion. Similarly, feed crops, which are very important in feeding livestock and preserving the ecological balance, also need insects for pollination. In plants like clover, the upper side of the flower organs is covered by a membrane; in these plants, bees break this membrane to get at the pollen; if it were not for bees, the pollen would remain trapped.

It is by Divine guidance that bees take nectar and pollen from the same type of plants all day. Even if there are other plants which contain more nectar and pollen, bees only stop at the type of flower that it first visited. The fact that bees collect nectar and pollen from the same type of plants all day long shows that this is not something they do randomly.

Like many other living things in the universe bees are in service to mankind, operating under the rules set by the Lord of the Worlds. However, activities that are carried out without investigating the meaning of the universe and the wisdom behind the creation of the living things, such as unplanned industrialization, which in turn has lead to an increase in air pollution, or the careless use of chemical materials, are the reason for a decrease in the population of bees, day by day. Never mind the wars and fires started by mankind, any venture that may cause the bees to disappear could lead to the destruction of mankind; if the bees become extinct, mankind will face many disasters, like erosion, desertification and the extinction of plants which are food for us and for the animals we raise.

Each creation is a work of art. All animals and plants, as well as every human being, are unique and priceless. And those who appreciate their value are like antique dealers as in the passage above. I recently had the chance to listen to such an “antique dealer,” Joanna Aizenberg of Bell Laboratories/Lucent Technologies, and witnessing the appreciation of the valuables she presented to us helped me better understand Said Nursi. Both the valuable object she was talking about and her appreciation of it were equally inspiring for me, and this is the reason why I have decided to share this story with you. Without any further ado, here is the story of a sponge species called the Venus’ Flower Basket and its “eternally” incarcerated residents: a pair of shrimp. Now, you must find what is hiding behind all this; after all, it is the eyes that look but the heart that perceives.

Venus’ Flower Baskets (Figure 1a) are vase-like sponges that grow upright on the sea floor of the Pacific Ocean, mostly around Japan. They have a very sophisticated mesh structure which caused medieval Europeans to assume they were glasswork made in China. In Japan they are called Kairou-Douketsu (together for eternity) and given as wedding gifts, since they generally house a pair of mated shrimp which are trapped in their cavity. As you have probably already understood, our story is about the engineering secrets of these sponges and their relationship with their guests.

The design

The skeleton of the Venus’ Flower Basket is made of silica, which is a very brittle material (remember the glass windows that you broke with your football when you were a kid; they were made with silica). How can these amazing creatures withstand the pressure and the currents present at the sea floor or the disturbance caused by two shrimp? The secret lies in the hierarchical construction of their cylindrical cage-like structure. As can be seen in Figure 1b, their skeleton is made up of beams that run perpendicular and parallel to the axis of the sponge, which forms a rectangular grid. This grid is further supported by beams that run diagonally in both directions. Finally, this whole structure is reinforced by ridges that spiral around. But these are just the macroscopic hierarchical levels of the construction. Now let’s start from the very first level of this hierarchy and try to understand how each level adds to the stability of the sponge.

The basic building block of the Venus’ Flower Baskets is a fiber composed of silica nano-spheres (Figures 1i and 2a) that grows around an organic filament (the black dots at the center of the circles in Figure 1f). Though this fiber is not very stress tolerant, due to the size of the spheres from which it is made, in the next level of hierarchy it is toughened by alternating organic and silica sheets that form a concentric lamellar (fine, alternating layers of different materials) fiber structure. The thickness of each layer in the fiber decreases from 1.5 (: 1/1000 mm) at the center to 0.2 towards the periphery (Figures 1f, 1g and 2b). Hence any crack that is initiated at the periphery is halted at the organic interlayers and while the thinner outer layers lessen the depth of crack propagation, the thicker inner layers enhance mechanical rigidity (in addition to their mechanical stability, these silica fibers are endowed with optical properties which are superior to man-made fibers, which will be discussed later on in the article).

Figure and captions from ref. 2.

Fibers of different diameters reinforced this way are then bundled loosely in a silica matrix (Figure 1d and 1f). The different diameter of the fibers in the bundle and the weak lateral bonding between them are essential for increasing the strength of the bundle against crack propagation. At the next level of hierarchy, these bundles are used as building blocks of the cylindrical cage of the sponge, being arranged horizontally and vertically into a square grid. This grid in turn is reinforced by diagonal bundles that run in both directions along every second square lattice. The minimum number of pin-jointed struts (i.e. ones that are free to rotate at the joints) per node needed in order to form a rigid two-dimensional grid has been shown to be six; this is the number present in the skeleton of the Venus’ Flower Basket. In fact, if the diagonal bundles were to run along every square lattice, the number of struts per node would be 8, which would be redundant for the stability in the skeleton.

At the early stages of the growth of the Venus’ Flower Basket the struts are not connected at the nodes. However as the sponge gets older the struts are joined by a silica cement which itself also has a lamellar structure (Figure 1e). Hence, while the younger sponges are flexible, the older ones are stiff; this also has important implications for the symbiotic relation that the sponge has with its guests, the shrimp. (This issue will be discussed in detail when the lifecycle of the shrimp is examined.) While the resulting grid is stable in two dimensions, in three dimensions it may still suffer from exterior effects, such as ovalization. This problem however is solved at the next level of hierarchy by the helical ridges that surround the grid (Figure 1b). The absence of the ridges at the base of the skeleton of the sponge where the cage diameter is small, and their increased density further up the cage where the diameter is much greater is proposed as evidence supporting this argument. Finally, this whole cage structure must be anchored to the sea floor in a way that will withstand the bending stresses caused by the currents. This is managed through the use of the fibers that have been discussed earlier; they are used as connectors between the base of the sponge that is anchored to the sea floor and the vertical struts of the skeleton, resulting in a flexible connection that enables the cage to swing freely in the currents (Figure 1a).

As a conclusion, it can be said that “The resultant structure might be regarded as a textbook sample in mechanical engineering, because the seven hierarchical levels in the sponge skeleton represent major fundamental construction strategies, such as laminated structures, fiber-reinforced composites, bundled beams, and diagonally reinforced square-grid cells to name a few.”

Now let’s concentrate more on the fibers (or spicules) that anchor the cage to the sea floor. These anchorage spicules (a term used for describing the skeletal structures of sponges which comes from the Latin word speculum, meaning the head of a spear or arrow)* are 5-15 cm in length and 40-70 um in diameter. In the above discussion we have briefly discussed the cross-sectional structure of these fibers that gives them their flexible, but resistant nature. Here we will focus on the optical properties of these spicules. But before doing so, let’s briefly explain how optical fibers work.

Optical fibers are silica fibers of a 5 to 80 um diameter that are coated with a cladding layer; light waves can travel in these for long distances by constantly bouncing off the cladding. The reason for this is the refractive index difference between the silica core and the cladding layer. Refractive index (n) is a measure of the ability of a medium to change the phase velocity of light and cause the light waves to bend while leaving one medium and entering another (refraction); in the case of fiber optics, leaving the core and entering the cladding. However, if the refractive index of the second medium is lower than that of the initial one, the incident light waves that have an incidence angle higher than a critical value or critical angle can be reflected back to the first medium and this is what happens in fiber optics (See red ray in figure 2). If the core diameter is small (5-10 um), light rays can propagate only through a single path in the fiber (which runs parallel to the fiber axis), hence these type of fibers are called single-mode fibers (See Figure 2a). If the core diameter is larger however, (60-80 um) several paths are accessible, and more paths will have incidence angles that are greater than the critical angle, hence they are called multi-mode (See Figure 2b).

Now with this information in mind, let’s have a look at the characteristics of the anchoring spicules of the Venus’ Flower Basket. First of all, as mentioned in the previous discussion, the lamellar structure of these spicules prevents crack propagation, which is the main failure mode of commercial silica fibers. This lamellar structure, however, also determines the dependence of the optical behavior of the spicules on the environment in which they are embedded. For instance if the spicules are embedded in an epoxide medium with a refractive index of 1.57, the spicule as a whole would not be able to act as an optical fiber, due to the smaller refractive index of the cladding. However, since the core region of the spicules has a slightly higher refractive index than that of the cladding, the core acts as a single mode fiber in such an environment (see Figure 2a). In sea water-the spicules’ native environment-which has a refractive index of 1.33, the whole spicule acts as a multimode fiber, since the refractive index difference between the core and the cladding is much smaller than that between the cladding and the surrounding sea water.

Another advantage of these spicules over man-made fibers is their formation/production parameters, which are ambient temperature and pressure; these enable the introduction of impurities into the silica. Though at first it may not sound as if impurities are a positive characteristic, these impurities are very important for increasing the refractive index of silica and act as dopants (impurity elements added to a semiconductor lattices in low concentrations in order to alter the optical/electrical properties of the semiconductor). The core section of the spicules, for instance, shows increased sodium concentration, which is the cause of the higher refractive index of this section. Such dopant introduction in the silica during the fabrication process, however, is not possible in the case of man-made fibers, due to the very high processing temperatures.

In addition to this, the spicules have crown-like caps at their base and thorn-like structures throughout their middle section. While the crown-like termini most probably are used to anchor the sponge to the ocean floor, it has also been shown that the waveguiding efficiency of the spicules increases when the illumination comes through the end that has the crown-like structure. Hence, it has been proposed that this structure may be acting as a light harvesting lens. The thorn-like structures, on the other hand, share the lamellar construction of the spicule body, and the light guided through the body branches out to these spines and emerges at the tip. Since sea water comes into contact with the tip at an almost perpendicular angle to the guided light, the coupling is pretty efficient. Hence the combination of crown-like ends and thorn-like structures forms optical networks that collect and distribute light. However, at the depths inhabited by the Venus’ Flower Baskets there is no accessible light source. If one accepts the fact that there is no waste in nature-whether one believes in “creation” or “evolution”-the existence of such an advanced network-like structure as a part of a sponge-the most primitive animal-is at least thought-provoking. In the case of sponges that dwell in shallower waters with similar spicules, it has been postulated that such spicules gather and provide sunlight for the sponge’s endosymbiotic algae. However, at the depths at which the Venus’ Flower Baskets live, direct sunlight is not available. However it has been suggested that if light sources, such as bioluminescent microorganisms (bioluminescence is the production and emission of light by a living organism as the result of a chemical reaction during which chemical energy is converted to light energy) or chemiluminescence (emission of light as the result of a chemical reaction) exist, their light may be efficiently distributed by the sponge and act as an attractant for juvenile shrimp that are searching for a host. But for now these suggestions are just speculation and merit further investigation.

Before concluding this section, we should also note that, as a natural outcome of their construction/composition, these spicules do not have as great a transparency as their industrial counterparts and light cannot be transferred over long distances with them. However, it seems this is not a problem for the Venus’ Flower Basket as, apparently, they just need fibers of 5-15 cm to survive and it is the scientists who need to figure out a way to incorporate the traits of the Venus’ Flower Basket into industrial fibers.

The love

As mentioned in the introduction, the Venus Flower Basket hosts a pair of mated shrimp. These belong to the family of Spongicolidae, the Spongicala japonica. These shrimp, which can be as “big” as 9 mm in length, spend most of their lives in their host sponge. Though studies about them are limited, it is believed that before permanently being entrapped in their host, the shrimp have two free- living periods. The first one is just after hatching when they are small enough to exit through the mesh of the sponge. During this period they exit and re-enter their cages and live in a group with their parents and other juveniles. Studies suggest that the females generally stay with their parents until sexual maturity, whereas the males tend to leave their original host and live a solitary life until they reach a length of about 4 mm.

The second free-living period comes at the time of sexual maturity, when it is believed that the male and female mate outside and then invade a host, or the female searches for a host that is already occupied by a solitary male. During this stage, the shrimp have a body length of 3.5 to 6.5 mm which is bigger than the mesh size of the host sponges. Though this seems puzzling, it is thought that the mated shrimp enter the sponge in its flexible stage-when it may be easier to penetrate through the mesh-and get trapped there “forever” as the sponge grows older and stiffer. In fact this theory is supported by the finding that several flexible sponge specimens host solitary and young mated shrimp, whereas in the stiff specimens only very few solitary and young mated shrimp have been observed.

FLOWERS:

For example, look at the pictures given below. For 1-petalled flowers, we offer white calla lilies; for 2-petalled flowers, we offer the very rare euphorbia; and for 3-petalled flowers trilliums, lilies, and irises.

<cellpadding=”15″ cellspacing=”15″>White Calla Lilly

Trilliums

Did you ever wonder why 4-petalled flowers are so rare, and why everyone gets excited when they find a 4-leaf clover? The reason for this is because such flowers are very rare, for 4 is not a Fibonacci number. Some violets and bluets also have 4 petals.

Flowers with 5 petals are rather common. Among them are buttercups, wild roses, larkspurs, and columbines.

Examples of 8-petalled flowers are bloodroots and delphiniums. Examples of 13-petalled flowers are ragworts, corn marigolds, and cinerarias; those with 21 petals are daisies, asters, and chicories; and those with 34 petals are oxeye daisies, sunflowers, plantains, and pyrethrums.

Some families of daisies, such as the michaelmas daisies from the asteraceae family, have 55 and 89 petals.

Seed and flower heads

The echinacea purpura is a member of the daisy family native to the Illinois prairie. You can see in Figure 1 that the orange œpetals seem to form spirals curving both to the left and to the right. At the edge of the picture, if you count those spiraling to the right as you go outwards, you will notice that there are 55 spirals (a Fibonacci number). A little further toward the center, you can count 34 spirals (another Fibonacci number). If you count the spirals going the other way, you will see that the pair of numbers (counting the spirals curving toward the left and toward the right) are neighbors in the Fibonacci number series.

The same happens in many seeds and flower heads, among them sunflower seeds, daisies, pineapples, and pine cones. The reason for this is that such an arrangement packs the optimal number of seeds so that no matter how large the seed head is, the seeds are always packed uniformly at any stage. As they are the same size in any given area, there is no crowding in the center and no scarcity at the edges.

The spirals form a pattern: The œcurvier ones

appear near the center, while the flatter ones, which are more numerous, appear the further out you go. Thus the number of spirals we see in either direction differs according to the size of the flower’s head. On a large flower head, we see more spirals further out than we do near the center. The numbers of spirals in each direction are (almost always) neighboring Fibonacci numbers!

Let’s observe the spirals in these beautiful arts of the Infinite Artist. Consider the daisy. In the close-packed arrangement of tiny florets in the daisy blossom’s core, you can see the phenomenon in an almost two-dimensional form. As shown in Figure 2 there are 21 (a Fibonacci number) counterclockwise spirals and 34 (another Fibonacci number) logarithmic or equiangular spirals. In any daisy, the combination of counterclockwise and clockwise spirals generally consists of successive terms in the Fibonacci sequence.

The Math Behind It

Botanists have shown that plants grow from a single tiny group of cells right at the tip of any branch or twig belonging to a growing plant or tree. This tip is called the meristem. They grow in size after their formation, but new cells are formed only at such growing points. Cells further down the stem expand, and thus cause the growing point to rise. This means that a growing plant produces seeds at the flower’s center, and that those seeds then push the other seeds outward. Each seed settles into a location that turns out to have a specific constant angle of rotation relative to the previous seed. This constant rotation forms the spirals.

Consider the following case. There are n seeds in the arrangement. The nearest seed is seed 1, the next one is seed 2, and so on. If each seed has an area of 1, we have a total area of n and a circle with a radius of from the area formula (Area= ). Given this, the distance from the center to each seed is proportional to the square root of its seed number. If we call this angle alpha, the angle of seed k will be alpha*k. So we can easily describe the location of any seed in polar coordinates with and theta=k*alpha.

If we chose an angle of 0.15 (54A) the result will be far better. But we will be done again after 20 seeds, for 20*0.15=3, so after 3 complete turns we will be back on the same line. If we choose 0.48, which is a little bit better than 0.15, we will come back to the original line in 25 rotations.

Therefore, speaking logically, if we choose an irrational number we will not return to the original line. Of course we will get close to it, since every irrational number has some kind of rational approximation. In nature, we mostly observe the so-called golden ratio, an irrational (1.618 = ), which is the root of the equation , which is the limit of the ratio of two consecutive Fibonacci numbers.

With this angle of rotation, each seed is rotated approximately 1.618 revolutions from the previous seed (i.e., 0.618 revolutions or 0.618*360=222.5A). Notice how well distributed the seeds appear; for there is no clumping and very little wasted space. Although the pattern grows quite large, the distances between neighboring seeds appear to stay constant. In nature, you can see that plants grow their seeds simply where there is the most room.

It is really amazing that a single fixed angle can produce the optimal design no matter how large the plant becomes. For example, once a leaf’s angle is fixed, that leaf will œdo its best not to obscure the leaves below and œdo its best not to be obscured by any leaves that will grow above it. Similarly, once a seed is positioned on a seed head, the new seeds continue to push the older ones out in a straight line. However, it retains the seed head’s original angle. The seeds will always be packed uniformly on the seed head regardless of the head’s size. The principle that a single angle produces uniform packing no matter how much growth appears thereafter was proved mathematically only in 1993 by the French mathematicians Douady and Couder.

We frequently observe the golden ration in nature. In addition, we can try flowers and flowers, at least mathematically and as models.

Conclusion

We look at nature and see God’s creation. Most people just look at the general design, but others also study the seeds and their designs. As the Qur’an’s first verse tells us to œRead, in the sense of reading the signs in nature (the Qur’an was revealed to a largely illiterate people who had no significant body of written literature), we should understand this as an indication to analyze nature.

As a mathematician, I see that God has arranged everything in nature according to a mathematical order. He puts the maximum number of seeds in a minimum area. Bees use hexagons to store the maximum amount of honey in a minimal space. This fact is even mentioned in Qur’an 16:68: Your Lord revealed to the bee. Those who believe in evolution say that the picture is very clear. But there is a great art in front of us, one which is very well balanced and in perfect accord with mathematical harmony. This shows that there is no luck or chance in the world, and that everything is based on the rules that God has laid down for His creation.

We all know there are laws in creation and everyone can benefit from them. However, man has been given the freedom to interpret them as he wishes. What is wrong is not the laws or the benefit from them, but the materialistic interpretation of those laws – modern science is a materialistic interpretation of the laws and of phenomena. Indeed, it never alludes to God or His existence. The method of materialist science, the so-called scientific method, is deterministic. It is based on causality. That is, it claims that things are causally related to each other, i.e. that causes produce their effects. However, in order for a cause to produce an effect it has to be able to produce the whole universe in which that effect takes place. For, an effect cannot exist without the whole universe being there first to enable it. Materialist science speaks about causes as though they were creative agencies or ‘gods’. Belief in causality is the antithesis of the belief that ‘there is no god but God’, which is the core of the Qur’anic world-view.

In order to begin to develop an appropriate method of inquiry, we need first to define the general goals of the Qur’an, to understand how it instructs us in its basic aims such as the Divine Unity, prophethood and resurrection, and how it teaches us to look at creation.

The Qur’an does speak about the natural phenomena around us. For instance, it mentions water about 60 times, the heavens 310 times, and the earth 451 times. Drawing attention to the countless benefits and purposes in the creation of each entity, the Qur’an reminds us that such benefits and purposes can only proceed from absolute knowledge, will, power, and mercy.

While causes are adjacent to their effects, in reality causes and effects are both created. The Qur’an leads our attention from causes to the Creator of causes. It calls us to read the signs of His wisdom in the universe, leading us to knowledge of our Maker with all His Beautiful Names. In short, the Qur’an teaches us that none other than Him, no thing, no cause, can be an object of worship, that all thanks and praise are due to Him alone. It makes us understand that we have been created to be worshippers.

The aim of Islamic science, corresponding to the aims of the Qur’an, is to make known the Creator with all His Beautiful Names and to confirm Divine Unity, resurrection and prophethood.

Materialist science on the other hand studies entities for themselves, in order to master (and exploit) their properties. By contrast the Qur’an speaks only briefly of the nature of entities and their material properties, but dwells at length on their duties of worship, i.e. how and in what respect they point to their Maker’s Names there is nothing but extols His limitless glory and praise (17.44).

Indeed, when Muslim scientists, thinking Islamically, look at the universe around them, they understand that they are glorifying their Maker, reciting and revealing His Names, hidden behind the veil of causes.

Resisting epistemic tyranny

Muslims must choose either the Qur’anic method or the scientific method, since the two are incompatible. That does not mean reading the Qur’an and neglecting study of the universe. It means studying the universe under the guidance of the Qur’an and not studying it, as materialist scientists do, only under the guidance of unassisted human reason.

For strictly materialist scientists, any hypothesis that does not argue according to the scientific method and accept its authority is to be disregarded. The extreme version of this position, expressed in Eddington’s famous remark – ‘What my net won’t catch isn’t fish’ – is an attitude that can only be described as epistemic absolutism.

Muslim scientists should not submit to this tyranny; if they do, they are bound to become imitators of scientism. Muslims know that materialist science does not produce knowledge of God, yet they dare not question it. They proclaim that they accept revelation as the basis of knowledge but, in practice, they test it for consistency with the scientific method. They seem not to realize that a scientific method that does not yield knowledge of God cannot be acceptable to Muslims.

Only when we take Revelation as our point of reference and follow the Qur’anic method do we begin to see how biased and illogical the scientific method of justification is. Consider this example:

Take two plants, both exposed to normal sunlight. Water one regularly; do not water the other. After some time, we see that the plant which has not been watered wilts. This is supposed to demonstrate that water is one of the causes of normal plant growth. In fact all that we observed was this:

In the absence of water plants do not grow. This is altogether different from saying that water is among the causes that make plants grow. The growth of plants depends on innumerable factors. The absence of only one of these factors is enough for a plant not to grow. The experiment does show that plants do not grow in the absence of water. It is logically unjustifiable to leap from there to the conclusion that ‘water is an agent or cause of the growth of plants’.

This sort of reasoning reminds us of the incident in the life of the Prophet Abraham, upon him be peace, when he faced the tyrant Nimrod (Qur’an, 2.258). Nimrod argued with Abraham and claimed that he could give life as well as death. To prove his claim, he asked for two prisoners to be fetched, ordered the death of one and spared the life of the second. Nimrod’s reasoning was that if he had had the second prisoner killed, he would not be alive. Therefore, he had given him life. This is similar to how the scientists argue that if there is no water, plants will wilt and die: therefore water gives life to plants.

The reason is that materialists take the conjunction of events for causality. That is, if two events coexist, they imagine that one causes the other. And in their determination to deny the Creator they make claims like: water causes plants to grow. They never ask how water knows what to do, how it does it and what qualities it has that enable plants to grow.

Asking positive questions

The Qur’an teaches us to ask questions, to lift the veil of causes and investigate the reality behind. It asks us to look, for example, at the endless benefits found in water and in the growth of plants and food so vital for life. Then it instructs us how to ask positive questions like:

Does water possess the knowledge and power to grow plants? Does it know the laws and properties of the formation of plants? Does it know their structures and have authority over them? Indeed water acts in a masterly way in all living organisms. Without its help we would perish. Yet, how can we claim that water possesses such qualities as power, knowledge, will, compassion?

Water is an unconscious entity; it has no will, knowledge or power. It can only be the submissive servant of One who has the power to create it and all plants and food, who knows all living beings and their needs. That is, the Creator and Disposer of water knows everything and has control over everything. His mercy and compassion encompass all things. Water must be in the employ of the One whose knowledge, will, power and compassion are all- comprehensive, absolute.

Consider a flower. How does its beauty come about? Can the unconscious seed, or soil or sunlight produce it? Do they have the knowledge, the power or the will even to make a flower, let alone make it beautiful? A flower can only exist with the whole universe in place first: to produce one single flower, therefore, one must be able to produce the whole universe in which it exists, that is, have absolute power, knowledge and will, which are the attributes of God alone.

In short, when we ask positive questions like ‘Can water cause the growth of a plant?’, ‘Can soil or sunlight produce a flower?’ belief in causality collapses. From this, we conclude that the scientific, or rather the materialistic, paradigm of knowledge, does not constitute sound knowledge.

Qur’anic method: the staff of Moses

The efficacy of the Qur’anic method may be likened to the staff of Moses. It swallows all the deceptions of materialist science.

And (then) We inspired Moses, ‘Throw down your staff!’ And lo! It swallowed up all their deceptions: Whereupon the truth was established, and vain was proved all that they had been doing. (7.117-8)

Materialist scientific knowledge cannot meaningfully explain the phenomena around us. Rather, it conjures up the idea that, for example, water is a strange entity that can mysteriously achieve miraculous things. Such distorted descriptions cannot fulfil our need for knowledge and understanding. Indeed, to attribute absolute knowledge, will and power to an unconscious entity is nothing more than superstition.

By using technical words like photosynthesis, mitosis, etc., to describe events, materialist scientists ‘cast a spell’ on people’s minds so that they appear to have given them a wholly satisfactory explanation:

And when they threw down (their staffs), they cast a spell upon the people’s eyes and struck them with awe, and produced mighty sorcery. (7.16)

In fact, the ‘mighty sorcery’ of materialist science is no more than that: They follow nothing but surmise and their own wishful thinking (53.23).

Whereas materialist science seeks mechanical advantages over the phenomena of nature, knowledge following the Qur’anic paradigm seeks understanding and meaningfulness. It tells us about things in order to make known their Creator with His Attributes and Names. It produces new knowledge, the knowledge of God. As if a molecule of water were saying in its own way ‘Look! I am unconscious and powerless, but I perform infinite duties which require absolute knowledge and power. Do you not see that I am acting at the command of the Possessor of Absolute Knowledge and Power?’ For this reason, a Muslim scientist is not merely an expert, but essentially a worshipper, an ‘abd, one who should not imitate the modern-day sorcerers of the Pharaoh but say, instead:

‘God’ and leave them at play with their vain talk (6:91).

To Muslims, study of the universe is desirable and acceptable because (and if) it yields knowledge of God and belief in God.

An Islamic science must work hand in hand with Revelation and proceed under its guidance. Otherwise it will fail to explain anything; it will fail to produce sound knowledge. It must seek out the wisdom and mercy in the creation, and thereby improve human beings’ understanding of themselves, the universe and the Creator. Bare information about natural phenomena can be transformed, using the Qur’anic method, into knowledge of God and wisdom (hikma). In this way, the purpose of creation, which is the worship of God, is fulfilled:

And I have not created the jinn and men to any end other than that they worship Me (51 :56).
