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

Pros

  • Attractive Design

Cons

  • back plate looks warped, likely printed on paper

Best Uses

    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.

      I got this for my husband for our 10th anniversary. It was perfect as it has aluminum in it (the modern 10th anniversary gift). He loved figuring out how the equations worked, particularly the binary code as he is a software engineer.

          My boyfriend is a high intelligent individual that is excellent at math and excels in academics. We crack jokes that he is a mix of Leonard and Sheldon (BBT) and I am Penny LOL. I thought this would be one of the perfect gifts for him because he would "get" the meaning behind the equations to figure out time. Love it!

            I purchased this clock as a Christmas gift for my son who is a senior in college, majoring in mathematics and economics. He is very happy with the clock, and enjoyed solving each hour marker, but admitted he had to peek on two of them! Thanks for a great product : )
