# The Geek Clock Tells Time With Equations

As many of you may know, I'm a rocket surgeon so reading this clock is like second nature to me. But for the rest of you, hopefully by now you've figured out what numbers typically go where. The Geek Clock runs $25 and would make a great addition to your cubicle, right next to the, 'I Break For Ï€' bumper sticker. LOL! I swear, you've always had the best taste in bumper stickers.

Hit the jump for an explanation of each number.

**12** - a radical

**1** - Legendre's constant is a mathematical constant occurring in a formula conjectured by Adrien-Marie Legendre to capture the asymptotic behavior of the prime-counting function. Its value is now known to be exactly 1.

**2** - A joke in the math world: An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The bartender says, "You're all idiots," and pours two beers.

**3** - A unicode character XML "numeric character reference."

**4** - Modular arithmetic, also known as clock arithmetic, is a system of arithmetic for integers, where numbers "wrap around" after they reach a certain value. The modular multiplicative inverse of 2 (mod 7) is the integer /a/ such that 2*/a/ is congruent to 1 modulo 7.

**5** - The Golden Mean...reworked a little.

**6** - Three factorial (3*2*1=6)

**7** - A repeating decimal that is proven to be exactly equal to 7 with Cauchy's Convergence Test.

**8** - Graphical representation of binary code.

**9** - An example of a base-4 number, which uses the digits 0, 1, 2 and 3 to represent any real number.

** 10** - A Binomial Coefficient, also known as the choose function. 5 choose 2 is equal to 5! divided by (2!*(5-2)!)

**11**A hexadecimal, or base-16, number.
