I can just imagine where you are getting your "facts" from...fact is that Muslims were expert at taking others' cultural and scientific achievements and translating and transmitting the as their own. Most of the so called Muslim/Arab math we hear about was simply taken from the ancient Greeks and Persians as they were conquered. Nothing wrong with that I suppose but to say that it was the arab Muslims who did it is just plain ignorant.
Well, then I am ignorant. I am working from memory of things I've read over the years.
They have beautiful architecture. Wasn't the Alhambra built by muslims? I saw a movie where there was an old house in the south built like the Alhambra. It had fallen into disrepair but was a gorgeous house. Can't remember the name of the movie. Can't remember the name of Salman Rushdie's book, either.
