Above Average Arithmetic

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

Clock movement, aluminum bezel, and glass cover made in China. Clock dial and hands made in USA. Assembled in Los Angeles, CA.

    Comments about EQUATION GEEK CLOCK:

    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 got this as a gift for my boyfriend. He is studying to be an actuary and this was the perfect gift for him! So excited to give it to him for Christmas. I think he's going to love it. No problems with shipping and the product works great!
