The class will follow the Earth from the Big Bang to the formation of continents using Robert Hazen’s excellent DVD lectures from the Teaching Company.

We’ll view two 30-minute lectures per class, each followed by 20 minutes for questions and discussion. (The full course has 48 lectures; we’ll cover the first 24 in the fall with the final 24 in the spring.)

Instructor Dick Chase, who worked 27 years as a research physicist for Ford and taught physics at several levels, will lead this class for those 50 and above. It will meet for two hours on Tuesdays from September 19 through December 12 (except for November 21).
