Eternity PKGHATAK, MD No. 25. Eternity. Eternity means forever. Eternity is not limited by constraints of time and “everlastingness” means forever, but within the boundary of time. In ancient Egypt, the Pharaohs made elaborate arrangements for an eternal life after death. The pictorial writings on the walls of the secretive burial chambers and their elaborate funeral books tell their stories of how a pharaoh accumulated wealth and man-power for his comfort for eternity in the afterlife. It is said that as soon as a new pharaoh ascended to the throne, he would start collecting money, gold, and valuables for that purpose; not unlike the Washington congressmen who s...

The plaque says : Niagara Falls, NY, the First Major Hydroelectric Power Plant in the World – Tesla's Greatest Achievement. And in recognition of his work on AC current, it has become possible to transmit electricity to distant places, and the Buffalo community owes him for the growth and development of Buffalo. Tesla: Tesla was born in a Serbian family; the place where he was born now belongs to Croatia. He studied science at two universities but did not graduate. He worked in Paris  at the ...

It is hard to find anyone beyond high school who has not heard the story of Newton, who went to his mother after the Cambridge University was closed during the London plague of 1665. There, sitting under an apple tree, he watched an apple fall to the ground. From this observation,  he discovered Gravity. The truth is that Galileo (February 8, 1564 to February 15, 1642 ) discovered gravity 100 years earlier. Newton developed the mathematical interpretation and expanded it to other spheres of science. Calculus: Gottfried W. Leibniz. A German philosopher and Isaac Newton both developed Calculus independently of each other. Leibniz published his p...

Walking on Fire PKGhatak, MD No.22 The travel brochures for Fiji, Vietnam, or Thailand prominently display a man walking barefoot on the burning amber. This is not a gimmick but a real event. After walking on the burning charcoal, the man willingly allows anyone to examine his feet, and no burns are visible. Is this magic or the mind over matter. The answer should be easy for anyone who cooks regularly or occasionally. If you bake a dish in the oven at 400°F, and open the oven door to take the dish out. The inside of the oven feels hot, but it would not burn the skin. However, if you touch any metal accidentally, you would have a painful burn. Hot metals conduct heat f...

Ghost PKGhatak, MD. No.21. Is death the end of a person. Can science provide a definite answer to this age-old question of the ultimate fate of the life force of the diseased. One does not have to be a scientist to define what is living and what is dead. Humans are not the only living thing on this earth - plants, animals, and even bacteria also live here. Any scientific theory is acceptable as a fact if it is valid in every instance and in every condition. That means we must recognize that every non–human living organism also has a life-force or a soul. That idea is rejected by all Western people who consider themselves religious. But a vast majority of pe...

Renal transplantation is in high demand in the USA and even more so in other parts of the world. In most cases, the kidney failure is a slow process and takes several years. In advanced countries the renal failure can be further slowed with medical treatment before a kidney transplant becomes essential. The increasing incidence of Type II diabetes is one of the main reasons for the increase. Liver transplant, heart, and lung transplants are also on the rise, but the incidence is not near that of the renal transplant rate. In an article, Mr. Jim McCartney, a freelance writer, states that at a given time, 90,000 patients are waiting for a...

Gordius was a poor Phrygian (Turkey) peasant who became king of Phrygia by an oracle. He tied his wagon to a pole with an intricate knot, with the ends of the rope hidden and prophesied the qualification for the future ruler of Asia. No one could untie the knot until Alexander of Macedonia in 333 BCE came and cut the knot with one chop of his sword. This story is similar to the one about Christopher Columbus making an egg stand on its end at the dinner table during the reception given by Queen Isabella of Spain for his discovery of America....

   Radical PKGhatak, MD No.18. One can find the word 'radical' in mathematics, chemistry, political science, other branches of science, and common English. It denotes an extremist, revolutionary, or an entity outside the normal boundary. In biology, radicals are highly reactive forms of oxygen and nitric oxide, and their derivative molecules, which are generated inside the body from metabolic activities. An average adult person uses 380 liters of oxygen in a day and generates 10 to 20 thousand molecules of radicals. The body is well equipped with anti-radical agents to neutralize radicals. Anti-radicals prevent substances from reacting with oxygen;  they are also called antioxidants. When the balance shifts towards radicals, harmful effects take place. The science is solid up to this point. The list of the deleterious effects of radicals on the body is growing from the beginning. Now, Alzheimer's disease to heart attacks, cancers, aging, and wrinkles on the skin a...

An ever-present dictionary is following you like a shadow, or your Gene of the Aladdin and the Magic Lamp fame. Today, her name is Artificial Intelligence, simply AI. Ask AI about the dream. The following answers she gave me to my questions:  Simply stated, dreams are '' a series of thoughts, images, and sensations occurring in a person's mind during sleep,” Oxford dictionary. Like humans, rats, spiders also dream during sleep, not to speak of cats and dogs. When challenged to prove this, she cites depressed activity of the prefrontal cortex, documented by instrumentation. Well, is not non-excitatory stage indicative of activities of t...

A video gamer will recognize the word 'Half-Life' instantly. The video game he is playing has an accompanying soundtrack provided by the famous Kelly Bailey, who established the Half-Life line of music.  Here, we are going to a different tract. Ernest Rutherford, while studying radioactive materials, discovered that the radioactivity of radium decays over a given time. He called the time taken for the decay of half of the material the Half-Life. Later, this concept was adopted by the Pharmaceutical industry. Suppose your doctor hands you a prescription for your cold and fever, which lasted for 5 days. You look at it before handing i...

Fungi PKGhatak, MD No.15 Fungi are neither plants nor animals; they are of their own species. Fungi appeared on this Earth about 1.5 billion years ago and plants appeared 700 million years ago. Fungi are mostly multicellular, but yeasts are unicellular fungi. The key chemical signature of fungi is the presence of Chitin and Glucans. Chitin and glucans are complex carbohydrate molecules, present in the fungal walls and provide structural integrity to the skeleton of fungi. We tend not to notice the fungi around us. When a mold forms on a piece of bread, or when we develop athlete foot, we admit fungi are all around us. In the US, Valley Fever is an example of a syst...

Sweetness is a basic taste. We use several different sugars, such as glucose, Lactose, and table sugar, but the intensity of sweetness among sugars varies. Many chemicals also have a sweet taste, for example, Aldehydes, ketones, and sugar alcohols. Some chemicals are sweet even at low concentrations, such as Aspartame, Saccharin, Stevia, and Sucralose. It is reported that motile bacteria move in the direction of sweets and newborn babies prefer sweeter sugars than lactose, a milk sugar, present in the breast milk. The sweet tooth is not just an expression; it has an ancient heritage. In the earlier days, honey was only a sweet treat...

The water covers 70 % of the surface of the earth, and 70% of our body weight is water. Someone said we carry sea in our blood, meaning sodium chloride, which is present in the seawater; the same salt is also present in our blood. The concentration of salt in seawater, however, is different. The salt present in the seawater is several times higher, 3.5 % to our 0.4 %. The Blood is a transport medium; to function normally, the osmolarity of the blood is strictly regulated within a narrow range. Solutes move from a higher concentration to a lower concentration, and to move in the opposite direction, a separate mechanism is present, where energy has to b...

The world has witnessed many pandemics in the past, and recently, we are just about to witness the resurgence of COVID-19, which raged from 2020 to 2024 and took 7 million people worldwide and sickened nearly one billion according to the WHO. The unofficial number of deaths is three times that of the official numbers. Plague,  Smallpox, Cholera, and Influenza pandemics visited this earth over and over in the past. The records of these infections were not kept in the official documents, but were mentioned in the contemporary papers and books. The first Plague pandemic of 430 - 427 BCE, known as the Athenian Plague, took two-thirds of th...

P.K.Ghatak, MD No.11 Occasionally, you may overhear someone commenting,” he is an animal.” Is he comparing the person with a flatworm or an octopus. Do not be surprised to hear that flatworms and octopuses are animals with intelligence. Remember George the Octopus of Germany. George could predict the winning soccer team almost flawlessly during the 2010 FIFA World Cup. Biologists, Psychologists, Neurologists, and Fortune tellers were all puzzled and could not offer any answer to George's ability to foresee events. However, if you are an Indian, you would say that it is easy, as George had “Divya Chakshoo” - a Sanskrit word meaning divine e...
