    I always though Al-Khwarizmi was Arabian as that is what I was tought in school. In the March 25 2006 "By the numbers" It says he is Persian:wink:

    They're referring to this item:
    * The Persian mathematician al-Kwarizmi considered 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31 to be unlucky, due to their nature as prime numbers. However, 6, 28, 496, and 8128 were lucky, as they are "perfect numbers" (numbers whose divisors add up to the number: 1•2•3=6, and 1+2+3=6).

    al-Khwarizmi was definitely born in the Persian Empire, near 800 AD.

    As if we need more evidence: Archaeologists have uncovered his passport and it was issued by Persia

    However, it didn't have the holographic markings, so it's assumed to be a fake.

    I have doubts about the passport. Back then, weren't over 80% of Arabians in Persia undocumented emmigrants?

    Let's not exaggerate. It was 78.9%. Which still leaves 21.1% that were properly documented.

    Since al-Kwarizmi considered all of those #'s unlucky, what made 13 stick out the most?
