Tributes(致哀)poured in last week to the world-famous British physicist Stephen Hawking, whose insights 1 modern cosmology(宇宙学)and inspired global audiences in the millions. He died at the age of 76 on March 14.

Hawking was given only a few years to live after being diagnosed with ALS(肌萎缩性脊髓侧索硬化症)at the age of 21. The illness left him in a wheelchair and largely 2 to speak expect through a voice synthesizer(合成器). Nevertheless, Hawking completed his doctorate(博士学位)on the origins of the universe three years later and became a research fellow at the University of Cambridge’s Caius College.

Hawking’s first major 3 came in 1970. With mathematician Roger Penrose, Hawking used Einstein’s theory of relativity(相对论)to 4 the origins of time and space to singularity(奇点),a single point of zero size and infinite density(无限大的密度)where all the laws of physics would have broken down. Their work gave mathematical expression to the Big Bang theory(创世大爆炸理论). Hawking was the first to try to 5 relativity with quantum mechanics(量子力学). In 1974, he put forward that black holes leaked radiation, now known as“Hawking radiation,”and would eventually disappear with a tremendous explosion. The proposal 6 to one of the most passionate debates in modern cosmology—before Hawking, it was widely accepted that black holes were completely black and would 7 forever.

In 1982, Hawking was among the first to show how tiny changes in the distribution(分布)of matter might give rise to the 8 of galaxies(银河系)in the universe and lay the seeds of stars, planets and life as we know it.

For 30 years, Hawking was Cambridge’s Lucasian professor of mathematics(卢卡斯数学教授席位),arguably Britain’s most distinguished chair(席位)and a post once held by Sir Isaac Newton. He received 12 honorary degrees and was awarded a Companion of Honor(英国荣誉勋位)by Queen Elizabeth in 1989. The 1988 publication of A Brief History of Time won Hawking international 9. The book, through which the professor brought complex science to a10 audience, has sold at least ten million books in 40 languages.
