Time To Embrace Your Inner Geek

While everyone else was watching the clock, you were paying attention during math class, storing away square roots and factorials for a day where you could prove your mathematical prowess.

Well, my geeky friend, that day has come. Pictured before you is a clock, where all the numerals have been replaced by the equivalent notation! How will we ever know what time it is unless you solve them all?

Cheat Sheet (included with each clock):
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.

    The clock lives up to its name as a "geek clock." I love the design. It's reasonably priced. I also like the fact that it's quiet--I don't hear the clock ticking (a problem I have with most clocks).

      A coworker found this clock and recommended it to me. I now get to teach my other coworkers what it means. I'd give it a 5, but the site won't let me.

      Good if for a gift for one of your coworker, cause quality is poor. It's all plastic so it's not a fancy gift. I offered one to my friend and that looked very cheap.

          Comments about Geek Clock:

          The clock keeps good time. The cost of this clock must be based on the fact that the clock face is unusual. The materials the clock is made out of is just plastic and not especially heavy plastic. I purchased this clock because of the math symbols on the clock face since I teach math. In that regard, my purchase filled the bill. The clock is clever! I think the purchase price should have been less because of the inexpensive materials used to produce it.

            This was a gift for my engineer-son. He was delighted to have it for his new home-office. The family thought it was perfect for him; and we all had good laughs that my son understood everything on the "cheat sheet"; and the rest of us knew nothing!

                      I gave this as a gift to a math geek. It was a great idea. However, the materials are really cheaply made. Just a sticker on plastic.
