Stephen Hawking, renowned theoretical physicist and author of "A Brief History of Time," has died at age 76.
The British scientist is being mourned around the world, and not just by fellow physicists and cosmologists.
Hawking was a household name, appearing on "The Big Bang Theory" and "Star Trek: The Next Generation," voicing his own animated character on "The Simpsons" and "Futurama," and inspiring the 2014 film "The Theory of Everything."
"We have lost a truly beautiful mind, an astonishing scientist and the funniest man I have ever had the pleasure to meet. My love and thoughts are with his extraordinary family."
"I feel so lucky to have known such a truly great man who's profundity was found both in his work and the communication of that work. Both in person and in books.
He virtually created the publishing genre of popular science. A heroic feat to bring the wondrous complexities of the universe to all outside of specialists in this field. But truly courageous when considering it was achieved by a man who lived a life trapped in his body from the age of 21 when he was diagnosed with motor neurone disease.
His support of the sciences, art, education and the NHS and charities such as the MND foundation will also live on, as will his wickedly funny sense of humour.
I will miss our margaritas but will raise one to the stars to celebrate your life and the light of understanding you shone so brightly on them for the rest of us. You were and are a true inspiration for me and for millions around the world. Thank you."

As we near Pi day (3.14) I join the global community in mourning the loss of the greatest physicist of our era. #StephenHawking is free from the physical constraints of this earthly condition we all exist in and he is soaring above us now marveling at it all. pic.twitter.com/o3V0TZrppj
