Reply #1: The history of Muslim scientific achievements in the Middle Ages is not "hidden".

[Aristus]

All one has to do is read a book. It's all there.

And Muslim achievement in science decreased due to an all-too-familiar problem we still see today: Religious fanaticism. What happened to Islamic science during our own Renaissance is happening to the Western world today. Religious fanaticism (Christian rather than Muslim this time) is crowding out and putting down scientific inquiry and advancement. That's why we have "Creation Museums" and concerted efforts on behalf of religious fundamantalists to push science instruction out of the public schools.

Another hundred or so years of this, and we here in the United States will be beheading "heretics" and drowning our teenage daughters in the family swimming pool for the crime of falling in love.
