Cosmic Recycling: We are Made of Stars
Yesterday evening, I caught the end of that lecture on UWTV: fascinating and entertaining!
From http://www.uwtv.org/programs/displayevent.asp?rid=1067:
Scientists today understand the universe in a very different way than they did 50 years ago. They understand the origin of every atom, something that Bruce Margon, a University of Washington astronomy professor, regards as "a fundamental intellectual triumph." What's more, those atoms all have been recycled several times over. The bottom line, Margon says, is that we are made of stars.
