Different from the controversial threads that is. I'm watching a special on Stephen Hawking right now and already I'm finding it absolutely fascinating. It's about his life, not just his scientific work. http://www.space.com/24455-stephen-hawking-pbs-documentary-wednesday.html I saw him when he came to Seattle. I took my son. There were people outside with signs begging for tickets, offering money. For a man whose stardom revolves around science, that was incredibly uplifting.
