Renowned scientist Stephen Hawking sadly passed away last night at the age of 76. The visionary physicist, who suffered from ALS, was given a life expectancy of two years following his 1963 diagnosis. He lived for another 53 years. He clearly had a lot left to accomplish on this earth.
Hawking is probably best known for his work with Roger Penrose, involving the theory of relativity and black holes, but he was also a mathematician, cosmologist, award-winning author and to many, a great philosophical mind. Many Twitter users took to social media to share his most touching quotes in the wake of his death. Others opted to share their original art, created in his memory. Here are some of our favorite tributes to an exquisite mind.
