Three years since the death of renowned physicist Stephen Hawking

Today it's been three years since Stephen Hawking, one of the world's most popular physicists, passed away.

He closed his eyes forever at the age of 76 in his Cambridge home.

The English man was known for his work on black holes and relativity, and he also wrote several popular scientific books including “A short history of the time”.

At the age of 22, doctors had given him only a few years of life after he was diagnosed with a rare nervous illness. The disease left him in a wheelchair and almost unable to speak.

Hawking had gradually lost the use of his hand, and in 2005 he began controlling his communication device with the muscle movements of the pages, with a rate of about 15 words per minute.

Stephen William Hawking was born on January 8, 1942, in Oxford, Great Britain, and was one of the world's most popular theoretical physicists.

He was astrophysicist, and since 1979 he owned the Lukasian cathedral and math professor at Cambridge University, once held by Isaac Newton.
