A Great  Story of a Great Man.... You must read this ................................
Stephen William Hawking
Stephen William Hawking was born on 8 January 1942 (300 years after the death of Galileo) in Oxford, England. His parents' house was in north London, but during the second world war, Oxford was considered a safer place to have babies. When he was eight, his family moved to St. Albans, a town about 20 miles north of London. At the age of eleven, Stephen went to St. Albans School and then on to University College, Oxford; his father's old college. Stephen wanted to study Mathematics, although his father would have preferred medicine. Mathematics was not available at University College, so he pursued Physics instead. After three years and not very much work, he was awarded a first class honours degree in Natural Science.
Stephen then went on to Cambridge to do research in Cosmology, there being no one working in that area in Oxford at the time. His supervisor was Denis Sciama, although he had hoped to get Fred Hoyle who was working in Cambridge. After gaining his Ph.D. he became first a Research Fellow and later on a Professorial Fellow at Gonville and Caius College. After leaving the Institute of Astronomy in 1973, Stephen came to the Department of Applied Mathematics and Theoretical Physics in 1979, and held the post of Lucasian Professor of Mathematics from 1979 until 2009. The chair was founded in 1663 with money left in the will of the Reverend Henry Lucas who had been the Member of Parliament for the University. It was first held by Isaac Barrow and then in 1669 by Isaac Newton.  He is currently the Director of Research at the Centre for Theoretical Cosmology, at DAMTP in Cambridge.  
Stephen Hawking has worked on the basic laws which govern the universe. With Roger Penrose he showed that Einstein's General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. These results indicated that it was necessary to unify General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century. One consequence of such a unification that he discovered was that black holes should not be completely black, but rather should emit radiation and eventually evaporate and disappear. Another conjecture is that the universe has no edge or boundary in imaginary time. This would imply that the way the universe began was completely determined by the laws of science.
His many publications include The Large Scale Structure of Spacetime with G F R Ellis, General Relativity: An Einstein Centenary Survey, with W Israel, and 300 Years of Gravity, with W Israel. Stephen Hawking has three popular books published; his best seller A Brief History of Time, Black Holes and Baby Universes and Other Essays, The Universe in a Nutshell, and most recently in 2010, The Grand Design. There are .pdf and .ps versions of his full Publication list
Professor Hawking has twelve honorary degrees. He was awarded the CBE in 1982, and was made a Companion of Honour in 1989. He is the recipient of many awards, medals and prizes, is a Fellow of The Royal Society and a Member of the US National Academy of Sciences.
Stephen Hawking continues to combine family life (he has three children and three grandchildren), and his research into theoretical physics together with an extensive programme of travel and public lectures.


 
Communication system 
Stephen William Hawking  Said:-



"I communicate with a computer system. I have always used IBM compatible computers, on my wheel chair. They run from batteries under the wheel chair, although an internal battery will keep the computer running for an hour if necessary. The screen is mounted on the arm of the wheel chair where I can see it, more recent systems have the whole computer in a box on this arm. The original systems were put together for me by David Mason, of cambridge Adaptive Communication. This company manufacture and supply a variety of products to help people with communication problems express themselves. Recently, Intel engineers designed a new computer for me powered by a Pentium II processor, which I now use. 


On the computer, I run a program called Equalizer, written by a company called words plus inc. A cursor moves across the upper part of the screen. I can stop it by pressing a switch in my hand. This switch is my only interface with the computer. In this way I can select words, which are printed on the lower part of the screen. When I have built up a sentence, I can send it to a speech synthesizer. I use a separate synthesizer, made by Speech+. It is the best I have heard, though it gives me an accent that has been described variously as Scandinavian, American or Scottish. I also can use Windows 98 through an interface called EZ Keys, again made by words plus. I am able to control the mouse with the switch through cleverly selected process from a small box shown on the desktop. I can also write text using similar menu's to those in Equalizer. I can save what I write to disk. I write papers using a formatting program called TEX. I can write equations in words, and the program translates them into symbols, and prints them out on paper in the appropriate type. I can also give lectures. I write the lecture beforehand, and save it on disk. I can then send it to the speech synthesiser, a sentence at a time. It works quite well, and I can try out the lecture, and polish it, before I give it. "
