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 Pictured before you is a clock, where all the numerals have been replaced by the equivalent notation!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 was delivered broken. The packaging was poor. No protection for the product other than a cardboard packaged box. This is why the product broke.

    Great in theory, not the best quality

    Comments about Geek Clock:

    I was very excited to find such a perfect gift for my friend, but when it arrived, I was pretty disappointed. The display (with the equations) was actually just a piece of printed paper laid on the back of the clock and it was bubbled at the top, which just made it stand out even more. There was no way to get inside the clock to try to glue or tape down the display. I guess the picture just made it look a little more "sturdy"

        I bought this gift for my boyfriend who is an engineer and math "geek". He loved the clock, and has shown it off to all of his college buddies, and they joke about the formulas, etc. The first clock that we got ticked really loudly and was consistently falling behind, but Uncommon Goods was great about a replacement. The new unit is so quiet that I often forget that there's a wall clock in the room, and it's been accurate so far! I really think that the first one was just a one off dud in bunch, or perhaps got a little too jostled during the holiday deliveries, (even though it was packed really well). All in all, the gift is fun and functional, and highly recommended for any math "geek".

              I gave this as a gift, and it was very well-received. Every time I see it, I think how great it looks on the wall. I chose it, though, because I really liked the variety and complexity of the equations. I wanted something that wasn't ordinary and I definitely got it!

              Service and delivery comments:

              This arrived very fast! I was glad because it had been back-ordered and had just become available again. I wanted to give it as a gift a week away from the day I ordered it. It arrived within days.
