Equation Geek Clock

Add a mathematical twist to the everyday with this equation wall clock.

Learning to tell time is so grade school. Indulge your inner geek and accept a new challenge with this nerdy clock. Each numerical hour of the day is spelled out with a different mathematical notation, giving you a new mathematical boost with each time check. For nascent mathematicians and victims of the occasional memory lapse, a cheat sheet is included with each clock:

1: i is equal to the square root of -1, so i^2= -1. The absolute value of -1 is 1.
2: This represents 2 in binary code.
3: The cube root of 27
4: 11 base 3, which represents 4 in the ternary system
5: Log(20x)=2 is equivalent to 20x=10^2 or 20x=100, where x=5.
6: Euler's product formula: phi(p^k)=(p^k)(1-(1/p)), where (p^k)=9
7: This is a binomial coefficient, so with the formula n/k = (n!)/((k!)(n-k)!), n/k=7.
8: This is a natural logarithm where ln(e^x)=x, so ln(e^8)=8.
9: This summation is equal to 3(1)+3(2)=3+6=9.
10: Since clocks "wrap around" every 12 hours, the hour number starts over after it reaches 12. This is arithmetic modulo 12. 10mod12 is 10:00, and 16mod12 would be 4:00, for example.
11: B'L is Legendre's constant, which is equal to 1, so this equation becomes the square root of 121, which is 11.
12: Hexadecimal representation of 12

After reading lots of reviews, I gave this clock to my father-in-law for Father's Day and was pleasantly surprised. Others had complained about the second hand and he received his clock in perfect functioning order. With him being a retired electrical engineer that made a living building satellites, I was worried that the equations would be too simple for him, but he LOVED it!!! He said that it was nice that the clock reminded him of math he hadn't used in years. He was thrilled that it had a second hand because he has put the clock up in his garage (at my suggestion) for while he is working on his functioning model steam locomotives. It helps him do some very precise timing that is needed when doing "steam ups". He is a very happy Dad. Thank you!!!

I received this as a gift this christmas, the minute hand was hanging. It was quickly replaced (thanks!), with the same problem. I figured out how to fix it (a quick fix to open up the back of the clock and take it apart) but the problem is the minute hand doesn't have a groove to snap in place. Design flaw. After this repair, it's running great, it's very attractive, and fun to have in my house. I would recommend this to a friend who is comfortable taking things apart.

    Comments about UncommonGoods Equation Geek Clock:

    Great idea for a clock and it has a nice, clean design. The only downside is the minute markings....there's one extra between each hour marking, so according to the clock, there are 72 minutes in an hour. Not really a huge deal as you can still get a good idea of the time, but you'd think someone who figured out all these advanced equations would also be able to count

      Lots of versions of this concept, but this is the best one. Equations on it are sufficiently obscure to remain a challenge, and the typeface is clear.

          He is a difficult person to buy for. Never asks for anything (since he was 6!). But this was right up his ally since math and physics go hand in hand! He hung it on his bedroom wall as soon as he got home.

                    Comments about UncommonGoods Equation Geek Clock:

                    This is a very attractive clock, and usually a conversation piece. I wish the back plate was made of a higher quality print than paper. The back plate looks warped, which makes the clock look cheaply made.

                    Service and delivery comments:

                    The service and delivery was exceptional and the clock was properly packaged.
