Many have said what effectively stunted Islamic culture was the rise of the Wahhabi fundamentalist Islam movement in the 18th Century.

But before that movement rose up, Islamic scientists and mathematicians created the base for much of our modern science. Indeed, the development of algebra and trigonometry--spurred on by the need to find the direction of the holy city of Mecca from anywhere in the world--became the basis for modern calculus. And they had a goods trade that was essentially second to none in the world (after all, the prophet Mohammed was a merchant based in Mecca for much of his early adult life)--indeed, Arab merchants set up trading posts all over the Middle East literally right behind the conquering armies.

Revisionism Non-sense!?! Euclid created geometry and other Greeks created trigonometry and calculus. Babylonian and Greek algebra preceded the Arabs.
