Just posting a shout out to the Islamic Golden age. While we lost out own math, they translated it and discovered much more because Islam back then was a religion of idea. Unlike Christianity which killed knowledge seekers. That's why a brain drain happened and people who were smart lived in Baghdad. Like the one that happened in the west but has more of less moved to China. Like 75% of the stars have Arabic names. We use Arabic numerals. Our computers run thanks to Araibc algorithms.
