Great post about Hawking!
I actually ran into him in Oxford once upon a time.
We were walking away from a bookstore, and we saw approaching us a man in a wheelchair with his nurse.
It was an amazing moment when we saw who it was, we looked in his eyes with awe, as he looked into ours. Just the look that passed between him and us was remarkable.
Really unforgettable to see him.
I'm sure.
