"people think physicists are really bright ...but most of what we do is absolutely wrong, that's just the nature of innovation"
DNLee posted a blurb in The Root about Sylvester Gates. He's the african-american scientist who was just awarded the National Medal of Science. I remember him from my childhood. I didn't know him personally, but a family member of mine knew him way back when. Whenever there was a write up or PBS appearance by Dr. Gates it would find it's way to my desk.
My html-foo fails me, so no embed, but here is a link to one of his PBS videos on String Theory. And another mini-interview. I had a good one of him talking about race in his science career that I saw (on VHS!). If I ever find it I'll post it.
