Jon Anderson from Western Michigan University pointed out in an email already five months ago that I had an error in the discussion of epicycles in lecture 8. I wrongly attributed the idea of epicycles to Eudoxus of Cnidus, while it is due to Apollonius of Perga.
Now that my last and final paper in oceanography has been accepted and is with the printer I can finally spend more time again on Science, Civilization and Society. I fixed the error and added a brief personal page for Apollonius. I'll upload the new pages next Thursday (26/7) when I get to the office again. (The university firewall does not allow me to upload pages from home.)
