Arabs had nothing to do with the invention of the modern place-value based, base-10 numerals which replaced the cumbersome and impractical Roman numerals. Guess the original source of that invention...

From what I’ve read there were a few scientists in Muslim countries. However most of them were killed.
The role Muslim dominated Spain had in the renaissance of Western Europe in the High Middle Ages has been way overblown. And Driftdriver is right. Many of the early Muslim scientists were not Arabs. They were Assyrians who already were experts in science before the Arab Muslims showed up. Muslims later turned against much of the scientific development they themselves had helped foster. The Muslim world gradually became a backwater - and remained one until now. The Jordanian Minister of Education (maybe it was Culture?) admited a few years ago that the entire Arab Muslim world translated fewer books into Arabic over its entire history (1400 years) than Spain translates into Spanish in a single year. BACKWATER!
