For anyone without anything better to do with 42 minutes, you can now watch the talk I delivered at Harvard University in September online. The talk was delivered in two halves, if you will, one of which discussed 10 great astronomical advances in history and another half that quickly covered basic info about comets, with ISON rapidly approaching.
The event took place on Thursday, September 19, in the historic Phillips Auditorium of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. I had been invited by David Aguilar and Christine Pulliam, Harvard’s tireless duo of outreach wizards, and spent a couple days talking with a variety of scientists at Harvard and at the Smithsonian Astrophysical Observatory. Some of their research will be showing up in the pages of Astronomy soon.
For now, check out the talk, if you wish.
