Stephen Hawking has passed away

Wednesday, March 14th, 2018

NPR The Two-Way: Stephen Hawking, Who Awed Both Scientists And The Public, Dies.

“There aren’t very many scientists who achieved rock-star status. Stephen Hawking, who has died at the age of 76, family members told British media early Wednesday, was definitely a contender.

“He was a great scientist and an extraordinary man whose work and legacy will live on for many years,” the family statement said, according to The Guardian. “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.””

I read his most famous book “A Brief History of Time” (Eine kurze Geschichte der Zeit) years ago, but think I’ll re-read it now.
