March 14, Birth Anniversary of a Great mind; Albert Einstein

ALBERT EINSTEIN; MARCH 14,1879 to APRIL 18, 1955
March 14, 1879, Ulm, Germany to Jewish parents, Hermann and Pauline Koch Einstein, a child was born named Albert Einstein. No one knew that in future this boy unfolds the many magical secrets of Science. Einstein supposed to the most intelligent person of this world till now. In 1905, his three most important scientific papers published;
"On a Heuristic Point of View concerning the Production and transformation of Light" (published on June 9) which deals with the quantum hypothesis, showing that electromagnetic radiation interacts with matter as if the radiation has a granular structure (the so called photoelectric effect).
"On the Movement of small particles suspended in stationary liquids required by the molecular -Kinetic Theory of Heat" (published July 18),his first paper on Brownian motion, leading to experiments validating the kinetic-molecular theory of heat; and
"On the Electrodynamics of Moving Bodies"(Published September 26), his first paper on the special theory of relativity and land mark in the development of modern physics. A second, shorter paper on the special theory, published November 21, contains the relation E=mc2 in its original form.
In 1921, He was awarded by Nobel Prize in Physics for Photo-Electric Effect.
He was not only a Genius but a great human being also.The story of Einstein's famous brain is give below
Einstein's body, from which the brain and eyes were removed during the autopsy, was cremated late in the afternoon of April 18, the day he died. His ashes were scattered, probably over the Delaware River not far from Princeton, by his friends Otto Nathan and Paul Oppenheim. The news spread rapidly throughout the world as a flood of tributes filled the media.
     What happened to Einstein's body shortly after his death has become well known. His brain and eyes preserved for future study. The pathologist, Dr. Thomas Harvey, who performed an autopsy, removed the brain without permission and kept it in a jar of formaldehyde. Another pathologist, Dr. Henry Abrams, took the eyes with the permission of the hospital administrator and received a letter of authenticity from Dr. Guy Dean, Einstein's personal physician at the time of his death. Apparently this procedure is not uncommon during autopsies.
     After the cremation, the astounded Einstein family learned about the removal of the brain. According to the account of Carolyn Abraham in her book Possessing Genius, Otto Nathan was in the morgue during the autopsy and aware of the removal. The family agreed to let Dr. Harvey keep the organ if he used it only for scientific study. He gave at least three parts of it to other scientists, but until recently only one of them had made any use of it. In 1985, Professor Marian Diamond of the University of California at Berkeley, in an article in the medical journal Experimental Neurology, reported that Einstein's brain had an above - average number of glial cells (which nourish neurons) in the areas of the left hemishpere that are thought to control mathematical and linguistic skills. Since then Sandra Witelson, a neuroscientist at McMaster University in Ontario, Canada, published some research results on the brain in June 1999 in the British medical journal Lancet. Witelson's group conducted the only study of the overall anatomy of Einstein's brain after Dr. Harvey offered to give them a section of it in 1996. The researchers compared Einstein's brain with the preserved brains of 35 men and 56 women known to have normal intelligence when they died. They discovered that in Einstein's case, the part of the brain thought to be related to mathematical reasoning - the inferior parietal lobe - was 15 percent wider than normal on both sides. Furthermore, they found that the Sylvian fissure, the groove that normally runs from the front of the brain to the back, did not extend all the way in Einstein's case. Witelson theorized that this latter feature may be the key to Einstein's intelligence because the absence of a full groove may have allowed more neurons in this area to establish connections among one another and work together more easily. Other parts of Einstein's brain appeared to be a bit smaller than average, putting overall brain size and weight within a normal range.
