Everybody is the scientific world is aware of Stephen Hawking and his contribution to�physics in general and to�Cosmology in�Particular.
He is considered as the best Physcist and cosmologist alive today. He Occupies the seat of Lucassian professor of Mathematics at the Cambridge University which was earlier occupied by many great scientists like Sir Issac Newton and Paul Dirac.
This blog is for those who are little aware of this great personality and his his contribution.

Stephen Hawking was born in Oxford on 8 January 1942 to Frank and Isobel Hawking. He had two younger sisters, Philippa and Mary, and an adopted brother, Edward. From the age of 11, he attended St Albans School. He applied to study mathematics at University College, Oxford, but ended up studying physics there instead. He read for his PhD at Trinity Hall, Cambridge.

Hawking is severely disabled by amyotrophic lateral sclerosis, or ALS (a type of motor neuron disease commonly known in the United States as Lou Gehrig’s disease).�
Symptoms of the disorder first appeared while he was enrolled at Cambridge. He lost balance and fell downstairs, hitting his head. Worried of losing his genius, he took the Mensa International test, to verify that his intellectual abilities were intact. Diagnosis came when Hawking was 21, shortly before his first marriage, and doctors said he would not survive more than two or three years. He battled the odds and has survived much longer than most sufferers of ALS, although he has become increasingly disabled by the gradual progress of the disease.

He gradually lost the use of his arms, legs, and voice, and is now almost completely paralysed. The computer system attached to his wheelchair is operated by Hawking via an infra-red ‘blink switch’ clipped onto his glasses. By scrunching his right cheek up, he is able to talk, compose speeches, research papers, browse the World Wide Web and write e-mail. The system also uses radio transmission to provide control over doors in his home and office. Despite his disease, he describes himself as “lucky” � not only has the slow progress of his disease provided time to make influential discoveries.

Hawking’s principal fields of research are theoretical cosmology and quantum gravity. Another Contribution by Hawking to cosmology is the proposal for the Black hole formation after the Big Bang. Hawking developed a model in which the Universe had no boundary in space-time.

Hawking’s belief that the average person should have access to his work led him to write a series of popular science books in addition to his academic work. The first of these,A Brief History of Time was published on April 1,1988 and became a documentary in 1991 starring Hawking, his family and friends, and some leading physicists. It surprisingly became a best-seller and was followed by The Universe in a Nutshell (2001). Both books have remained highly popular all over the world.

In addition the above, he has published many scientific and technical papers which earned him money and fame. His plans to write a science book aimed for childern will defenitely give all the childern a requried enthusiasm for opting science as�their major.�

Let’s hope god will give him more life so that human species can�be benifited.���
