A few old friends are back.
Principles of Economics, J. Bradford DeLong (iTunes, course website)
DeLong gives Berkeley students the benefit his sharp wit and dry humor in this intro to economics. As in the past, DeLong provides open access on his website to lots of additional course materials such as lecture slides, lecture notes and problem sets.
Introduction to Biological Anthropology, Terrence Deacon (iTunes)
Deacon is back with one of my all-time favorite classes. In the past his class (iTunes) was a fascinating mix of biology, genetics, animal ethology and anthropology.
