Stephen William Hawking was born on January 8, 1942. Oxfordshire, England and passe
away on March 14, 2018, Cambeidgeshire. The English theoretical physicist whose theory of
exploding black holes drew upon relativity theory and quantum mechanics, he also worked
with space-time singularities in the early 1960s Hawking contracted amyotrophic lateral
scierosis, an incurable degenerative neuromuscular disease. He continued to work despite the
disease's progressively disabling effects. In 1971 he suggested the formation, following the big
Jang,
of numerous objects containing as much as one billion tons of mass but occupying only
the space of a proton. In 1974 Hawking proposed that, in accordance with the predictions of
quantum theory, black holes emit subatomic particles until they exhaust their energy and
finally explode. Hawking's work greatly spurred efforts to theoretically delineate the
properties of black holes, objects about which
it was previously thought that nothing could be
known.
Hawking's contributions to physics earned him many exceptional honours. In 1974 the Royal
Society elected him one of its youngest fellows. He became professor of gravitational physics
at Cambridge in 1977 and in 1979, he was appointed to Cambridge's Lucasian professorship of
mathematics, a post once held by Isaac Newton. Hawking was made a commander of the
British Empire in 1982 and a companion of Honour in 1989. In 2008 he accepted a visiting
