"Mathematicians are like lovers...Grant a mathematician the least principle, and he will draw from it a consequence which you must also grant him, and from this consequence another." - (Fontenelle, 1657-1757)


Math History Tidbit:

Zero: The number we call 0 has a long and fascinating history. While the concept of 0 was used by the Chinese in the fourth century B.C., it did not surface in the Western world until the 1200's. Leonardo of Pisa, better known as Fibonacci (1180-1250) advocated strongly for the use of Hindu-Arabic numerals (which included 0) in Western Europe. For a variety of reasons, the West resisted the use of the efficient Hindu-Arabic numerals. As late as 1298, the City Council of Florence (Italy) outlawed any system but Roman numerals. (How would you like to do operations like multiplication and division with Roman numerals?)

I guarantee you that research on the number 0 will yield some extremely interesting historical information.
