Our Magnetic Earth

-
  Our Magnetic Earth P.K.Ghatak, MD No.66 The Earth feels solid under our feet. We live on the mantle of the Earth in geological terms. The mantle of the earth is made up of soil, sand stones and mountains. The center of the Earth, the core, is made up of iron and nickel. The outer part of the core is liquid due to very high temperature, the primordial heat retained from the day the Earth was born some 4.6 billion years ago. The center part of the core is solid because of very high pressure, about 250 gigapascals. As the earth rotates around on its axis, the liquid outer core rotates in between the solid inner core and mantle. This rotation generates electricity due to the dynamo effect. The liquid iron becomes magnetized. The compass needle points to the north direction; actually, the North is the South pole of the Earth, [the opposite poles attract each other and similar poles repulse.] In our solar system Jupiter, Saturn, Uranus and Neptune have magnetic fields. Jupiter’s magnet...

Time Travel

  l'objectif principal de ce blog Pari Talks blodpsot.com est de tirer un sourire des amateus de science serie'ux, acun langage grossier n'est utilise'. The primary objective of this blog, Pari Talks blogspot. com is to draw out a smile from serious-minded science lovers, and no foul language is used.   Time Travel P.K.Ghatak,MD No.65 The publication of “The Time Machine” by H.G Wells in 1895, created a big sensation in the European scientific community. Some leading scientists of that period opined that going back to the days of yesterday was not possible. The gentlemen community of the U.K and the British Royalty did not like the description of a socialist system the scientist landed in. It must have brought joy in the under classes and destitute in London. We are sure that the Royals and the UK parliament did not try to suppress sales of this book. A lesson now forgotten in certain countries and the authors and publishers of such books are under the threat of lawsuit...

The Human Soul

-
  The Human Soul P.K. Ghatak, MD No. 64. No one knows when humans came to believe a life-force lives inside the body. The life-force continues to live after death. Today, even after all the advances in science, the nature of that life- force, better known as the soul, remains behind a shroud. Physics: Physics accepts findings as fact upon verifiable experiments under various conditions, otherwise, those remain as theory. Einstein's revolutionary papers on General and Special Relativity still remain as theory. Modern Physics finds no evidence of non-material soul within the human body. The science says that all human experiences like love- hate, anger and fear, memory, consciousness - all of that are non-materials are also real. But what constitutes the core of those experiences remains unknown. Quantum Physics: Quantum Physics places the human soul in between Science and Philosophy. However, the following properties of the quantum can be applied to the soul. 1, The observer effect....

AUTISM

-
  Autism. P.K.Ghatak.MD No. 63. Autism literally means self-absorption. A Swedish psychologist, Paul Eugen Bleuler coined the term in 1910. Autism is found to have many variable symptoms and sometimes the conditions can go on and is correctly identified in adult life. This led to a change in name, now autism is called Autism Spectrum Disorder, ASD.  The ASD is considered as a Neurodevelopmental disorder. ASD presents behavioral and social issues, and some others consider the ASD as a discipline problem. The newborns can recognize the voice of their mother at birth; some even say the recognition of mother's voice begins in the womb. By the time the children are 2 to 3 months old, the children turn their heads to their mothers, and the facial expression of the child expresses happiness and makes eye contact with his mother. It is natural, that the mother detects lack of personal connection and apathy of the child and begins searching for an answer and soon the autism diagnosis i...

Consciousness. A scientific inquiry

  Blog: Consciousness. A Scientific Inquiry. P.K.Ghatak, MD No.62. A flood of research papers was published recently on Consciousness. Behind the enthusiasm is a hard competition for leading a race to equip Robots with consciousness. In the past, such interests were generated when Neuroimaging technology was developed and particularly the “functional MRI” was introduced. The next wave of research papers followed after the publication of Dr. Jane Goodall's research on the social interactions and behavioral characteristics of the chimpanzees. Dr. Goodall discovered that Chimpanzees use tools, possess complex social behaviors and exhibit emotions like us. Many researchers inspired by Goodall, began working with subjects not limited only to the primates but also to birds, insects and even molluscans. One could recall Paul, the octopus who correctly picked the winning jersey of teams, 12 out of 14 times, when World Cup (soccer) was played in 2010 in Germany. What is consciousness. In th...
