Today Is Pi Day: Gadgets for Math Nerds to Celebrate [PICTURES]

    Pi Day is a yearly celebration of that useful, yet irrational and never ending number (3.14159265359). Pi is used to calculate the ratio of a circle's circumference to its diameter. The number has become an integral part of geometry, trigonometry and physics. But for die-hard fans, pi is much more than that. It's a predictable challenge, a constant that has a wild sort of beauty.

    Pi Day was first officially celebrated on a large scale in 1988 at the San Francisco Exploratorium. Since then, Pi Day has been celebrated by millions of students and math-lovers. The day is celebrated on 3/14, since 3, 1, and 4 are the three most significant digits in the decimal form of pi.
