Stephen William Hawking was a theoretical physicist, cosmologist and author whose area of study was mainly focused on the universe, its creation and cosmos.
At least three generations of science-aficionados today will remember him as the genius with the 'robot voice' who could do everything from his all-powerful throne.
From children's guides to memoirs and books, Hawking brought science to the masses in a way no scientist has ever done.

His passing has left an intellectual vacuum in his wake. But it's not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure. Stephen Hawking, RIP 1942-2018. pic.twitter.com/nAanMySqkt

The world has lost a beautiful mind and a brilliant scientist. RIP Stephen Hawking

R.I.P. Stephen Hawking. Among his many profound contributions to this world was this simple sentiment: “It would not be much of a universe if it wasn’t home to the people you love.”

A friend just pointed out to me that Professor Stephen Hawking dying today falls on International Pi Day (3.14), which is also Albert Einstein’s birthday. I don’t know enough about how the universe works, but that is a VERY freaky coincidence.

Stephen Hawking has passed away, which means the world’s a little less bright than it was yesterday.

The rest of us will just have to pick up the slack.
With Stephen Hawking's death (Obit: https://t.co/vmLfc6GtYu), we look back on a moment during our Envelope Screening Series chat on "The Theory of Everything" when Eddie Redmayne describes the physicist arriving on set. https://t.co/B6JmJJgfM9 pic.twitter.com/feoU5s5uyt
