Walt Woltosz on the passing of world-famous astrophysicist, Professor Sir Stephen Hawking
Walt Woltosz, chairman of Simulations Plus Inc., commented on the passing of world-famous astrophysicist, Professor Sir Stephen Hawking...
"Stephen Hawking was a remarkable man and a global scientific leader. But he was also charming and witty, with a nice sense of humor. He would "dance" in his electric wheelchair at festive events, spinning in circles and dazzling all who watched. He made his place in history, along with Newton, Einstein, Bohr, and so many others. He will be missed."
