A Unique Scientist 'Stephen William Hawking'

We known the universe is self existent and boundless, but one scientist said that it has been created and it will be vanished. He told us it has been made almost 15 billion years ago and from then time is being counted. Do you know who this scientist is? He is no other scientist, without Stephen William Hawking. He again said, the universe will be constructed. If that happens, time will be run the opposite.

When Stephen Hawking was about 21, he was attacked by Motor Neuron disease. Physicians said, “He will be alive only two years.” But he is still alive, all predictions are proved untruth.

Stephen William Hawking was born on 8^th January 1942 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 honors 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. 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. Stephen is still an active part of Cambridge University and retains an office at the Department for Applied Mathematics and Theoretical Physics. His title is now Director of Research at the Centre for Theoretical Cosmology.

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 Space-time with G F R Ellis, General Relativity: An Einstein Centenary Survey, with W Israel, and 300 Years of Gravity, with W Israel. Among the popular books Stephen Hawking has published are his best seller A Brief History of Time, Black Holes and Baby Universes and Other Essays, The Universe in a Nutshell, The Grand Design and My Brief History. 

After attacking Neuron disease, he always sits in a wheelchair. In spite of being wheelchair bound and dependent on a computerized voice system for communication Stephen Hawking continues to combine family life, he has three children and three grandchildren, and his research into theoretical physics together with an extensive programmed of travel and public lectures. He still hopes to make it into space one day.

Stephen Hawking knows about Bangladeshi noble laureate Professor Dr. Yunus well by internet, he likes Dr. Yunus and he is a supporter of Dr. Yunus coined Micro credit system. We wish our greatest scientist Stephen William Hawking, may Allah bless him.
