Stephen Hawking, celebrated physicist and author, passed away at the age of 76. A family representative informed the media. Hawking, regarded as one of the most brilliant theoretical physicists since Einstein was a former Lucasian Professor of Mathematics at the University of Cambridge. His book A Brief History of Time, has been widely read. In a statement issued, his children Lucy, Robert and Tim, said: “We are deeply saddened that our beloved father passed away today. He was a great scientist and an extraordinary man whose work and legacy will live on for many years. His courage and persistence with his brilliance and humour inspired people across the world. He once said, ‘It would not be much of a universe if it wasn’t home to the people you love.’ We will miss him for ever.” Hawking had contracted motor neurone disease in 1963 and was then told he had just two years. His perseverance, and defiance to admit defeat was noteworthy and was always lauded. News of his death has come as a shock to many as people have taken to social media to mourn his death.

And is still one of my favorite pieces of literature" Here are some of the tweets mourning Hawking's death. We were on earth at the same time as Stephen Hawking. That's kind of a miraculous thing. We breathed the same air as the man who demystified the stars. — Geraldine (@everywhereist) March 14, 2018 RIP Stephen Hawking. A brief history of Time shaped my last years of high school.

Not only did he defy the odds for 52 years, even as his body failed him, his mind soared. I hope his meeting with the Universe was beyond even his wildest imagining. 💜 — Caissie St.Onge (@Caissie) March 14, 2018 RIP Stephen Hawking. And may the force be with you.
