Yeah, but what HAPpened? We call Ptolemy’s astronomical work the Almagest because we got it from them, and many of the stars have Arabic names (”Alcor”,”Alkaid”, “Zubenelgenubi” and the like) . Alchemy? Of course it looks like algebra started in the Indies and only “passed through” Arabian culture. So it leads one to think that around the 13th century somebody slammed on the brakes.
Right. What happened is that they thought there was no culture that had anything to contribute to them, so they became completely insulated.
As the West went through the Renaissance, people in the West were learning and discovering all kinds of new things, taking the best of all the societies around them and so on, Islam was in a situation where someone had to make a ruling and issue a fatwa if an idea was proposed on how to make their ships better, but that idea came from an infidel vessel.
Thought that was a goat stew.
