Journeying to the Earth's Past in the Isotope Time Machine

by John M. Eiler as part of the Earnest C. Watson lecture series @ Caltech. This talk will explore how the study of isotopes in rocks and fossils lets us peer into the past and quantitatively reconstruct geological and biological evolution. Recent innovations allow to reconstruct ice ages hundreds of millions of years in the past and measure the body temperatures of dinosaurs. Official announcement see http://events.caltech.edu/events/event-8685.html

Meeting point would be 15 minutes before the talk at the entrance to the left of this round Beckman Auditorium. They have plenty of parking space in the evening at the junction of E Del Mar Blvd and S Michigan Ave right in front of this lecture hall. http://events.caltech.edu/find.html .
