Stephen William Hawking

Stephen William Hawking (1942-) is a British theoretical physicist. Because of his work in the field of gravity, Hawking is considered perhaps the most brilliant theoretical physicist working today.

Hawking’s best–known work is on the nature of black holes, a phenomenon suggested by Einstein’ s equations describing what might happen should a huge star die, proposing it would crush into its own centre with such strong gravitational force that nothing could escape, not even light. Introducing his own theoretical modifications, Hawking posits the existence of mini-black holes. Created by the tremendous force of the big bang, these mini-black holes would not only emit sub-atomic particles and radiation (now called Hawking radiation), but would gradually evaporate over the space of 10 ⁶⁶ years, only to explode with the energy of millions of hydrogen bombs. At the same time, Hawking is the first to admit that there is as yet no physical evidence that black holes actually exist.

Hawking is one of a number of scientists concerned with theories linking quantum mechanics and gravitation. The premise of these so called grand unified theories is that it is scientifically possible to prove how the universe came into being.

Hawking was born in Oxford, England. After graduating from Oxford in 1962, he went on to study at Cambridge. In his first year there, he was diagnosed with amyotrophic lateral sclerosis (ALS), otherwise known as Lou Gehrig’s disease of the nervous system. Confined to a wheelchair, he speaks through a computer synthesiser, and his movement is limited to a barely perceptible lifting of one finger and very little facial expression.

Hawking received his Ph.D. degree in 1966 from Cambridge, where he now holds the prestigious post of Lucasian professor of mathematics, a post once occupied by Sir Isaac Newton.

Hawking was among the youngest inductees into the Royal Society, one of the world’s most renowned scientific bodies. He has also received the prestigious Albert Einstein Award, has been named Commander of the British Empire by Queen Elizabeth, and has received honorary degrees from Notre Dame, the University of Chicago, Princeton, and New York University. In 1988, he published his book A Brief History of Time. He hoped the book would help non-scientists understand theories of nature, from the big band to black holes.
