Prof. Loh says that in Module 2, he talks about how the greeks figured out the circumference of the earth using shadows. When was that lesson? Also, I think the forum link (at the bottom of the question explanation) used to open the forum in a new tab. Now, it opens the forum on the tab of the lesson, so I can't see the lesson and the forum at the same time unless I click "open link in new tab."
@divinedolphin Thank you, I've fixed the forum links now, so I hope they work now! I looked through Module 0, Module 1, and Module 2, and I believe Prof. Loh didn't actually discuss the method that the Greeks used in the course. However, this would be a great livestream question! Maybe you could try asking him tomorrow at the livestream at 4:00 p.m. EST!
@debbie Oops, sorry, I forgot that there wasn't a livestream today. I'm sorry if you went there and were disappointed! We're trying to find the best time for the livestream, now that school has started and Prof. Loh has a new teaching schedule. Thanks for your patience
