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 Pictured before you is a clock, where all the numerals have been replaced by the equivalent notation!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.

      Bought this for a college Math Major. He loved it. The numbers are clear and the clock is a great novelty for him to put in his dorm room.

      The quality of the clock could have been a little higher. Plastic body was not as nice as I'd hoped. Great gift overall.

        Comments about Geek Clock:

        My fiance has been dying to geek out the guest bathroom, so I bought this awesome clock for him for Christmas. Physically, the clock looks really great. The display is awesome, the numbers are printed very crisply... It looked even better in person than I'd hoped.

        Unfortunately, it stopped working the moment we hung it up. The second hand made one single full rotation and then gets caught and stopped moving. It was kind of embarrassing just because it was a gift, but there's not much that can be done at that point.

        I'll be returning this for a refund, but I hope others have better luck than I did this time around. It really is a lovely clock. Perfect for any geek-lover as long as it works.

        The equations actually work out to correspond with clock numbers. My college math professor brother and my son (recipient of gift) talked about the equations and their meanings for a long time. My brother even said "this is better than the one in my office."

          A great concept, but flimsy construction

          By 

          from Mountain View, CA

          Verified Reviewer

          Comments about Geek Clock:

          I ordered this as a present for my husband for his birthday about a year ago. He's a math teacher, so I knew it would be a great gift. When he opened it, I was a little worried about the seemingly flimsy construction, but it was okay for awhile. However, just the other day, the hour hand inexplicably sunk down to the six and no longer has the ability to stay up. Such a bummer, as my husband really did love the clock. I guess we will look for something more conventional.

              Purchased as a Christmas gift for an mathematician. When I installed batteries prior to wrapping the gift it was evident that the hands were bent - the sweep hand stuck on the minute hand. I disassembled the clock and straightened the hands - hopefully it remains fixed and I don't have to return it.
