Stephen William Hawking, CH CBE FRS (8 January 1942 – 14 March 2018) was an English theoretical physicist and mathematician. He was born in Oxford. In 1950, he moved to St Albans, Hertfordshire. He was one of the world's leading theoretical physicists.[1] Hawking has written many science books for people who are not scientists.

Hawking was a professor of mathematics at the University of Cambridge (a position that Isaac Newton once had).[2] He retired on 1 October 2009.[3]

Hawking had a motor neurone disease related to his dyslexia,[4] and because of that he could not move or talk very well. The illness worsened over the years and he was almost completely paralysed. He used a wheelchair to move, and an Intel computer to talk for him. He died on 14 March 2018.

Early life and education[change | change source]

Hawking went to St Albans School, a local public school in Hertfordshire. At 17, he passed an exam to study at Oxford. He studied physics and chemistry there. Because he found it really easy at the beginning, he didn't study a lot for the final exams.

In October 1962 he started his graduate course at Trinity Hall. It was at this time that his illness started to show up. He had difficulties in rowing and then even simply in walking. However, he finished his PhD and wrote about black holes in his thesis. He then got a fellowship (a job as a university teacher) at Gonville and Caius College in 1965.

Career[change | change source]

Hawking was a cosmologist—someone who studies the structure of the universe (stars and space). He invented important theories about the Big Bang (the start of the universe), black holes and how they work.

Stephen Hawking predicted that black holes eject some radiation (energy), even though they normally swallow everything. That kind of radiation is named "Hawking Radiation."

Hawking also worked on the problem of quantum gravity. Quantum gravity tries to explain how gravity works with quantum mechanics (physics of tiny things.) That is a hard problem that scientists have not solved yet.

Hawking also wrote popular books about science for non-scientists. His first book, A Brief History of Time, sold over ten million copies.

Death[change | change source]

Hawking died on 14 March 2018 in Cambridge, Cambridgeshire at the age of 76.[5]
