Lecture 14b: Copernicus from Au2006
b"Because my voice recorder malfunctioned 15 minutes into my Lecture on\\nCopernicus on 2007 October 9, I've added this recording of my Copernicus\\nlecture from Autumn Quarter 2006. It is the same basic material, but\\nsince I generally improvise on a basic outline, there will be some\\ndifferences. Personally, I liked this year's lecture better, but this\\nwill at least cover most of the same material. Oh well."
