She stood at the edge of the abyss, the blinding darkness engulfing her, enticing her. It would be easy to let go, to wither away and join him. Her arms felt numb, and her powerful legs were weak. Violent tremors traveled up and down her body. A small compelling hand, wet with tears, tugged on her arm. “What will we do now?” a quavering voice whispered. She opened her eyes. The sky was a cerulean blue, and the blazing sun was beating on her torn straw hat, casting a slender shadow on the spring green rice fields. Her rapid heart was calmed by a wind that caressed her cheek. To her dead husband, to her children, to Vietnam, she dropped the condolence letter, and with her feet firmly planted on the ground, said, “We will live.”

To say it was easy is an understatement. Raising five kids as a single mother, in a country where women are expected to be docile, seemed infeasible. “I was taught at a young age that men were the head of the household, they were the heroes of the family,” Diep Ngo, aged 80, recalls sadly, her eyes distant. “I felt helpless. My brothers were charting new paths, while I was still, unable to move.” With a suppressed sob, Ngo recounts that at the twilight hour, she would drown with dark thoughts, but every morning when the sun rose, they would be vanquished. The roosters were the reveille that awakened her slumber, her empty stomach was the battle cry, and the last words of hope from her departed beloved, the mantra that carried her on. 

The war took its toll on the civilians of Vietnam; it was a disease that plagued families with deaths and injuries. Young girls were jailbirds, kept busy looking after their younger siblings, torn rags their striped attire and restrictions the bars of their prison. Dreams were locked away, replaced by the basic needs crucial to survival. Even so, when asked if she would take part in the war that claimed her husband, Ngo, her mouth in a straight line and her eyes ablaze, adamantly nodded. Raising both arms until her fists were level with her head, she mustered a grimace. Her nose crinkled and teeth bared, but her eyes sparkled with humor. “Do you think anyone would’ve thought twice about taking me on?”

Scraping bits and pieces of broken memories from her childhood, Ngo recalls that the only freedom she truly had was that from the pressures of education. “I never did well in school. Women were not expected to accomplish anything, so it was highly unusual for a women to achieve higher education.” Now, it seems clear that this supposed freedom transformed itself into another burden upon her shoulders, for she had to take on menial tasks when drafted into the position of “man.” For the first time in her life, she left the cage built by the patriarchal society and refused wealthy suitors. “They were bloated with pride… I would never submit to any man like that.” Ngo was ridiculed by her neighbors as a result, but she felt a strange sensation, absent from her life ever since the fateful, disappointed sigh that accompanied the doctor declaring her gender 80 years ago: the jewel of independence.

“As their father was gone, I had to step into the role of the provider. Oh, what a burden it was, but the power and purpose it gave me fueled the sleepless nights.”

Before the age of 30, her long, black hair turned a platinum gray, and impending wrinkles scarred her face as the war robbed her of youth. A moment to weep or reconcile with memories of loved ones was lost in the present.

“Losing my husband was truly hard, but myself, and other women of Vietnam, had to choke back grief and look to the future,” she remarked. Leaving the house militarily before the sun rose and coming back well after the crescent moon silently loomed in the sky, the only thing Ngo regrets is not spending as much time with her children. But, what she had to do was necessary, as every day was a battle. Even so, how could she explain to them the rough calluses on her hands, which toiled tirelessly, tending the infested wounds left after the hungry bullets pierced the heart of Vietnam? How could she explain yet another outline of a large palm on her red cheek, this time from an angry customer, unsatisfied by the knee-length trousers she had spent all night mending?

Through it all, she remained an eternal warrior, whose struggles rivaled those of men fighting raging wars. Diep Ngo battled gender inequality and injustice, all while leading her family through desperate times. An old poem by Xuân Diệu filled her thoughts as America, the land of rebirth and opportunities, slowly emerged on the horizon: “Your feet have hardly tread round this way… Open your arms to clasp the spring, then from your hand let there be light” (translated by Thomas D. Le). And for the first time since her husband’s death, she welcomed the moist tears, for the valiant soldier’s burden had been lifted. Her dauntless mission was complete. 

I’m forever grateful for her valiant decision to bypass social stereotypes and become a sort-of soldier, leading her family to survival, to new opportunities, to an education, to happiness, to America. It’s a natural, humane feeling that is respectful of the wisdom, the strength, and the sacrifices of the old. Every evening, after the tiring cycle of school, I retreat back into my place of comfort: my grandmother’s arms, and for the past 17 years, her past life was but a false, beautiful painting, rid of pain and hardships and suffering. That one night, under a blanket of softly twinkling stars, I retraced her hands, touching them, caressing them, tracing her old, calloused, scarred fingers and her bulging veins, to finally realize the truth: that there was so much I didn’t know about my hero.

Galaxy and the Sun

The 21 cm long radio wave radiation emitted from the hydrogen gas within the dense dust and gas clouds of the arms of the galaxy enables us to know about the structure of the galaxy. This information led us to conclude that our galaxy is indeed not a solid object and displays a circular motion of 250 km per second. The Solar system is estimated to complete one revolution around the galaxy in approximately 200 million years. At this point the critical question that comes to mind is how a solar system orbit is maintained and protected during these journeys where the solar system bypasses the gravitation and effects of strong heavenly bodies without causing disruption and collisions. The Earth just won’t become a habitable place only by considering planetary solutions. We may have to consider measures regarding our solar system and other galaxies, since the solar system has a very sensitive relation with the other heavenly systems in our galaxy.

The Sun’s position in the Milky Way

Trillions of comets in the Milky Way galaxy fill the outer space and encompass the solar system in a globular fashion. One of the comet groups orbiting the solar system is called Oort or Opic-Oort cloud. A hundred billion comets is estimated to exist in the Oort cloud.

These comets follow the designated orbits until they deorbit with gravity of another strong heavenly body other that the sun. Stars and masses of the Milky Way constitute a globular center with spiral arms where these arms extend out of the center in the same galactic plane. There are a limited number of systems located in the space between these spiral galactic arms. In fact, this is where our solar system exists. In other words, it deserves attention that the sun does not reside in the dense centric part of the galactic arm Orion (Hunter) but exists in the nearby sparsely populated galactic mid space. The solar system that has been placed in the most appropriate position within the Milky Way also needs to be protected from possible dangers it may encounter (like crossing paths with dense spiral arms) during its journey around center of the Milky Way.

Scientist who study the place of our solar system in galactic maps particularly point out that we are far away and safe from the devastating effects of cosmic storms.

If the solar system did exist in the arm where stars are densely populated and near each other, gravitational forces could result in changes in planetary orbits. For instance, in the spiral arms of the galaxy, comets would easily deorbit and bombard the earth momentarily under the strong gravitational force of these arms. Yet remarkable measures have been taken to protect against this as well! One of them is the velocity value of the Sun. For example, in order to provide an effective communication, a satellite positioned in the earth orbit is given a speed equal to the one earth has for rotating around its axis. Our sun is given a suitable velocity to move with almost the same speed of galactic arms without intercepting each other, thus providing a safe passage. However this is not the case in 95% of the stars and the spiral arms in our galaxy unlike the one determined for our solar system. This is something to reflect and think about. Another measure that prevents the sun from intersecting with the spiral arms is that it has a circular orbit rather than in the form of an ellipse like stars of the same age. Also in this regard, we observe that our sun is given a special movement allowing Earth to become a habitable place for life. The All-Wise and All-Mighty Creator works the galaxies just like a giant machinery wheel with his established laws.

The stars in the spiral arms may in time get sucked into the inner parts of the structure, not being able to hold on to their position for a long period of time. This is also applicable for the sun. Divine measures also intervene here and leave the sun in the protective zone. The sun is located in the “galactic common rotational radius” where strong spiral arm effects do not exist. Furthermore, when Supernova explosions take place, giant star debris can reach a couple thousand light years away, enabling the sun not to be negatively affected from these explosions since it exists in the outer regions of the arms.

Cosmic dangers in the galactic center

The solar system is 28,000 light years away from galaxy center. If our galaxy is considered to be 200 thousand light years wide, one can say that we are relatively close to the center.

This location in the galaxy is distant enough to be protected from the negative effects that could arise from the galaxy center. What would happen if the solar system was closer?

In this case we would constantly be exposed to dangerous gamma, X-ray, and cosmic radiations, therefore no life on Earth! Not to mention the black hole in the galaxy center which has a mass 3 million times as much as the sun. If the sun were to exist near the black hole, life on earth would again be negatively affected from the strong gravity of it. The extraordinary measures that have been taken for our solar system, the sensitive adjustments that are put in place, and the maintenance of such balance and complexity all displays a perfect science and a Divine power in the background. All these events demonstrate clearly that no single event of randomness and chaos exists in the universe. The most complicated and sensitive tasks are resolved in the best possible way, therefore revealing a perfect organization. We see this perfect organization between the Milky Way, the solar system and the earth!

The miracle of life appears in the form of a baby which develops from a fertilized ovule (zygote) following millions of other events. This series of events, which is almost always the same for every fetus, can be grouped as reproduction, differentiation, and development. The zygote completes its development in the womb; postnatal growth can continue until 20 years of age. Even though every event during the baby’s development seems to take place with chaotic reactions, harmony and order are there for us to discover. One of these astonishing events is the perfectly symmetric growth of the fetus/baby. Most organs in the human body appear in pairs and are symmetric. Babies are born with 300 bones; however, some bones later fuse with other bones, leaving only 208 bones in the adult human. It is still a mystery how long bones such as the humerus, radius, ulna, femur, and tibia are able to grow on both sides of the human body in a symmetrical manner.

Mechanisms that control growth in organs

In vertebrates, both internal developmental programs and the external factors which stimulate or inhibit growth play a role in the ultimate size of an organ. But the relative effects of these two mechanisms can vary significantly in different organs. When pieces of spleen from an embryo that is at a later stage of growth are transplanted to a newly developing embryo, each new piece grows, but not to the size of the original spleen. The total weight of all the transplanted spleen pieces is equal to a normal spleen’s weight. When the spleen reaches a certain weight, growth inhibiting factors are secreted, which stimulate negative feedback mechanisms that limit growth. When a spleen reaches a certain size, the density of the inhibiting factors increases simultaneously, halting growth. Growth in the liver is controlled by extracellular factors (various substances in the blood, hormones, vitamins, minerals, etc.). When a section is cut off of the liver, the section continues growing and developing until it reaches the size of the original liver. The thymus has a growth process that is executed by a cellular genetic program. When sections of a thymus taken from the embryonic period are injected into developing mouse embryos, every section grows until it reaches the ultimate size.

More evidence of cellular growth programs was acquired via an experiment that was carried out with the salamander genus Ambystoma. When the leg bud of the larger species was injected into the smaller species, it would at first grow slowly, but then it would reach the normal size of its own species (the larger species).

Distinguishing growth and symmetry from one another

Both the arms and legs have long bones. A long bone consists of two parts (diaphysis and epiphysis). The diaphysis is the middle (core) part of the long bone. It consists of hard bone tissue, and is like a tube. The hyaline cartilage-covered joint forms the epiphysis of the long bone. In a growing bone, there is a growth plate (epiphysis plaque) made of hyaline cartilage; this is located between the diaphysis and the epiphysis. The epiphysis plaque causes the bone to grow longer; when growth is complete, the epiphysis plaque ossifies (becomes bone). In other words, growth stops. There are some clues that show the existence of positive feedback mechanisms which control the symmetric and balanced development of the arms and legs while the fetus is still growing. The arms and legs grow due to the development and growth of the plaques located at opposite ends of the long bone. The ultimate size of the arms and legs are proportional to the size of the finger bones (phalanx) and the metacarpus. According to current knowledge, growth in our arms and legs is only controlled by internal growth programs and the active growth of the plaques. We do not yet know the mechanism through which how much the bone must grow and symmetrically with the organ (the other arm or leg) on the other side of the body. But even if this is discovered in the future, we will continue to appreciate the perfect and miraculous aspect of this phenomenon.

In addition, in growth-plaque transplant experiments, the development of the transplanted growth plaque is dependent only on the age and size of the donor. Growth plaques cause the bone to grow, but the plaques themselves remain the same size for years. The cartilage cells they produce (chondrocytes) exchange places with the bone cells (osteocytes) in harmony and without destroying the length of the bone. Cells from different areas of the growth plaque act differently. Stem cells are found on the upper section, near the epiphysis. Immediately above them is an area where cells reproduce very quickly. At the bottom of the epiphysis, the cartilage cells grow up to 4 to 10 times larger than their normal size (hypertrophy). Cell reproduction here is mostly due to hypertrophic chondrocytes. The chondrocytes die and break up, then change places with the bone tissue. The dynamic process of these events in the growth plaque repels it from the bone area, and as a result, the bone grows longer.

Sustained symmetry despite cell sequence and speed of reproduction

The rapid growth rate in the legs and arms during the embryonic period continues to increase until the child is three years of age. This growth rate slows down until the individual reaches adolescence. During the fastest growth period, which is from adolescence to the early 20s, the growth rate rapidly increases. For example, most people who grow between 30 and 37.5 cm during the first two years of life can grow between another 7.5 and 10 cm every year during adolescence. At the onset of adolescence, rapid growth due to a sudden change in the volume of cells is observed. After adolescence a sudden falling off in the speed of growth can be observed due to the effect of hormones on the growth plaques in the spine and other long bones. The growth plaque now fuses with the neighboring cells and growth stops. However, the fusing of the growth plaque is the result of the cessation of growth, not the cause. After growth stops, the growth plaques begin to disappear. When the reproduction potential of the cartilage cells in the growth plaque has been exhausted, the growth plaque begins to disappear.

Growth plaques in different bones can trigger growth at various rates; these rates can differ as much as seven times. In fact, growth plaques on different ends of a bone can have different growth rates, provided that this rate is consistent with the genetic program. The number of cells on the growth line is 40 times more than in other areas. The number of cells produced here can exceed 10,000 cells per day. For symmetric growth between the arms and legs to be sustained, the number of cells in the growth plaque must be the same or very close. Experiments carried out on rats show that eight cartilage cells leave the growth plaque to exchange places with cells above them every day. It can be said that the growth of the bone is caused by the increase of cells in the growth plaque (which sustains its size). The growth rate caused by the growth plaque can be calculated by multiplying the growth plaque’s cell production rate by the average length of all of its cells. Different growth plaques provide different growth rates. This difference can be caused by the difference in the size of the growth plaques, the difference in cell production rates, and/or the difference in the hypertrophy (growth) rate of every cell. The upper growth plaque in the tibia of mice generates 16,400 cells every day; the average life span of these cells is around 30 hours. Can such harmonious, symmetric, and equivalent growth in the arms and legs-despite the large number and variety of cells-be the work of pure coincidence, mindless nature, or unconscious molecules?

Do hormones play a role?

The main molecular players that organize longitudinal growth in bones during childhood are the growth hormone, the thyroid hormone, and corticoids. The sex hormones (androgens and estrogens) are programmed to influence growth during adolescence. Estrogen is the main determiner of characteristics related to increased height and an increase in bone quality, as well as adolescent-related physiology. These hormones are in charge of coordinating growth throughout the body. It is for this reason for women, after the menopause, the production in estrogen decreases and osteoporosis and brittle bones can occur. According to the current view, cartilage cells have a certain genetic reproduction potential, and when this potential finishes, growth stops. The growth rate during the embryonic period is 20 times higher than that of mid-childhood. The growth rate drops greatly during mid-childhood. If we exclude the noticeable increase during adolescence, the cells responsible for growth have begun to age. The bones on opposite sides of the body stay about the same size, despite all of these changes in growth rates. Circulating hormones and neuroendocrinal factors are believed to play important roles in maintaining symmetric growth. But there is no conclusive evidence to support this belief. Even though one can think of factors such as pressure, tension, and sports as helping control harmonious and symmetric growth of bones, no proof has been attained from controlled experiments. As a person ages, a gradual decrease in growth can be observed. Even if a growth plaque is placed into another organism, be it young or old, the growth rate of the bone does not change. This shows that symmetric growth in long bones is controlled by a program that is operated by internal factors, which is also compatible with the genetic program. When chemical-based medication is given to postpone growth, after the medication has been eliminated, the growth plaques grow faster for a short period to compensate for the lost time. These findings show that timing and the location and circumstances of the cell are critical parameters for reproduction. If the cartilage stem cells in the growth plaque have a certain reproduction potential, then it is clear that cartilage cell reproduction stops when growth comes to an end. If growth inhibiting factors slowly accumulate in the growth plaque, this might cause a deceleration of growth over time. Another possibility is some sort of “meter” in the unconscious and mindless stem cells, which keeps track of the number of cell divisions and thus controls aging. The estrogen in our body has a duty of closing down the growth plaques and speeding up the aging of cells. However, we should not forget that estrogen plays the special role of closing down all of the growth plaques at the same time. Estrogen is one of the visible causes of fertility, growth and development, and resilience. Estrogen also represents femininity and fertility at all levels.

When the signals from unconscious cells in the growth plaques and the quite sophisticated interactions among all the factors that influence growth, all of which require an all-encompassing knowledge to be executed, are taken into account, the impeccable genetic programs of different growth plaques on the two sides of the body that leads to the formation of the arms and legs, as if they have been molded in a factory, is absolutely amazing for anyone who reflects upon it.

WHAT MAKES THE BABY CALM IN HIS MOTHER’S ARMS?

According to some researchers, the rhythmic heartbeat of parents is one of the main factors that influence baby’s feelings. Several experiments have been performed based upon this hypothesis. Some babies who were crying for food were taken to a room where pre-recorded heartbeats and lullabies were playing. It was observed that the crying babies became silent and fell asleep in a short while. The researchers came up to the conclusion that, during pregnancy, babies become accustomed to the heartbeats of the mother in her womb. After the baby is born, this familiar sound becomes a sort of music that relieves the baby.

Most mothers unintentionally lean her babies on their left arms during breast-feeding and over their hearts when trying to lull them. This instinctive behavior leads researchers to focus on the impact of the heartbeats upon babies’ feelings.

Associate Professor of the College of Nursing at Marmara University, Nuran Komurcu, is a distinguished person who has dedicated herself to medical science and takes her inspiration from small details. She had even tried proving the truthfulness of her hypothesis that musical therapy was effective during the delivery of a baby. Dr. Komurcu had continued most of her studies in Bakirkoy Yenimahalle Maternity hospital. She usually used the beautiful sounds of nature such as the babbling sound of water and a mystic wind instrument, ney, which is used to perform Sufi music, for her experiments. She divided her patients into two groups and placed them in two different rooms. One room was prepared for patients who would listen to the kind of music mentioned above, and the other room was for the group who would not listen to any music. Meanwhile, one question raised from her mind, “what if the babies fall asleep in the mothers’ womb before labor?”

Dr. Komurcu then selected her patients among those who would most probably give birth to their babies first and made them listen to music just a couple of hours before delivery. Being treated in a very comfortable room, the patients almost did not have any fear of the delivery.

First, the patients who were regarded as experimental and the control group, were asked whether they liked music or not, what kind of music they listened to, and other questions concerning their personalities. Then, their blood pressure was measured. The measurement of the blood pressure was essential for the assessment of the experiment because it led to more accurate results among the other tests which are conducted for the determination of the effects of music, in terms of pain relieving, mood enhancing, and delivery stress. She hoped to see the stimulating muscle contractions caused by the ney, which is proved by former research. Her patients listened to the music at 20-minute intervals before the labor time. It was observed that the pain during the labor time became more frequent. This showed that the music decreased the labor period.

Music therapy is playing an important role to help patients gain self- confidence and subsequently overcome labor pain. The results state that the patients who listened to music during delivery were less tense and nervous than the other group. The determination of differences of blood pressure among the groups is assumed to be caused by the efficiency of music therapy on the blood circulation, respiration, and muscle physiology.

Having hypothesized that music could ease delivery, Dr. Komurcu has reported the beneficial effects of music therapy from her research. However, she emphasized that it would not just be enough to apply music therapy when women are in labor. It is recommended that music therapy be started at least 3 months before the expected delivery time in order to get full advantage of it.
