Hawking Turns 70

Tom Feilden at the BBC scored an interview with Stephen Hawking, who amazingly will turn 70 on Sunday.  I haven't listened to the interview, but I'm looking forward to it.  I read A Brief History of Time when I was a kid, and I've had a soft spot for Hawking since then, just for kicking open a box in my mind.

Happy birthday, Professor Hawking.  Thanks for all the light about light.  It's harder to say which is the greater contribution: the science or your spirit in doing it.
