On this day, 27 years ago, February 23, 1998 (January 27, 1998, the lunar calendar), Hawking considered the origin and destination of the universe that the universe had a beginning but no end. Stephen William Hawking, professor of the Department of Applied Mathematics and Theoretical Physics at Cambridge University, the most important contemporary general relativity and cosmologist, is one of the great men with international reputation in this century and is known as the greatest scientist alive. Hawking was born on January 8, 1942 in Oxford, England. He entered Oxford University in 1959, graduated from Oxford in 1962, and went to Cambridge to study for postgraduate studies. In the 1970s, he and Penrose proved the famous singularity theorem, for which they jointly won the 1988 Wolf Physics Prize. He also proved the area theorem of black holes. Hawking's life is very legendary. In terms of scientific achievements, he is one of the most outstanding scientists of all time. He held the most noble professorship ever held at Cambridge University. He was Lucason Professor of Mathematics, where Newton and Dirac held. He was a member of the Royal Society and the National Society of Sciences. There are twelve honorary degrees. He was awarded the CBE in 1982 and the honorary partner title in 1989. His published books include "The Large-Scale Structure of Space-Time" with G.F.R. Ellis,"General Relativity: Einstein's Perspective on the Century" with W. Israel, and "Gravity 300 Years" with W. Israel. Stephen? Hawking has two best-selling books: his best-selling book,"A Brief History of Time", and later "Black Hole, the Baby Universe and Beyond."
