This is a cool site:
http://muslimheritage.com/Just two small cool excerts:
1202AD Leonardo Fibonacci (born in Pisa, Italy), who had been taught mathematics in Bejaia (Algeria), publishes "Liber abaci" [Book of the Abacus"], the first European book to use "0" for Zero, and including his famous series 1,1,2,3,5,8,13,21,34,55... known to us a Fibonacci's Sequence.
http://muslimheritage.com/topics/default.cfm?ArticleID=218Europeans always claim they invented everything or discovered everything and never give credit to where they learned it from or where it's been taken from. Muslims documented everything, invented the scientific method, improved upon the old, experimented and proofed right or wrong, etc...
Optics even... muslims get no credit. Medicine, no credit. You have to REALLY REALLY sit your ass down and READ islamic history to know how much the modern world especially the west is to thank the Muslims.
I came to north africa with the mentality thinking all arabs are wild ferocious and dangerous 'the wild arab dog of the desert', all those popeye and other racist cartoons stuck in my mind since a child. The reality is far from these deliberate forged lies. The media is a powerful tool to distort realityt
The primary problem is NOT having ANY material in euro/christian schools on islamic history.
The second and perhaps worse off is 'orientalists' who distort and present the islamic history in a distorted and convulted manner. The whole 'moon god worship' for example is thanks to these idioitic orientalists. When such a belief for example is contrary to the fundementals teachings of islam.
You have to really be careful where you learn from... as there are people with ulterior motives trying to demonize islam and muslims.
