（全新版）大学英语《综合教程》第一册 Unit 3  Understanding Science I. Cultural Notes 1. Stephen Hawking (1942 -): a British scientist who has greatly influenced peoples ideas on the origins of the universe. He has devoted much of his life to probing the space-time described by general relativity and the singularities where it breaks down. And hes done most of his work while confined to a wheelchair, brought on by the progressive neurological disease. Hawking is the Lucasian Professor of Mathematics at Cambridge, a post once held by Isaac Newton. In the late 1960s, Hawking proved that if general relativity is true and the universe is expanding, a singularity must have occurred at the birth of the universe. In 1974 he first recognized a truly remarkable property of black holes, objects from which nothing was supposed to be able to escape. He has written the international bestseller A Brief History of Time. The book spent more than four years on the London Sunday Times bestseller list — the longest run for any book in history. 2.

There have been many films based on the story and variations of it: Everybody was dressed up as a ghost, a vampire or Frankensteins monster. 3.
