Ha, finally, I had room and time to watch and listen to your presentation. The only feedback that I have is that -maybe- get more pro design slides, but that would be just the cherry on top. Well done, it's a shame I missed it in real time, but I'm glad we spoke in person on the second day (I think you were talking a bit about citizen science with me)!
The Egyptian people were very accurate indeed... 0,1 degree off? Oh man... haha
Yeah maybe. Although I prefer to focus on the content than on the slides themselves ;)
See here for the story on the Earth radius. It was in Egypt, but the guy was Greek ;)
