I have a problem with the Classical Astronomy course. I have the course in ‘My Courses’ section alongside other courses and all other courses are working fine/displaying all the lectures, however, the Astronomy course has no lectures or information within and only shows the progress bar.02/09/2020 at 6:14 AM #344228AnonymousInactive
Not sure how to remove the topic posted, I have found that it was my foolish mistake as the course costs $125 and it seems that I have not purchased it yet. Sorry for that.02/09/2020 at 11:38 AM #344231William C. MichaelKeymaster
Thanks for posting.
The actual issue is that Classical Geometry is a prerequisite for Classical Astronomy. This is not an “astrology” course, where the the ancient interpretation of the movements of the stars is studied (that’s taught in Ptolemy’s Tetrabiblos), but the mathematical study of magnitudes in motion–mathematical Astronomy. It’s impossible to progress without mastery of Geometry.

FYI…Here’s a link to an English translation of Ptolemy’s Tetrabiblos, which I mentioned above, if that’s what you’re hoping for.
