För dom som vill ha lite mer utamning i vardagen eller vill briljera med sina matematikkunskaper. För alla vet väl att kubikroten ur 1728 är 12? Inte? Du behöver inte känna dig ensam, jag förstod inte än siffra (jo, förresten nummer 8). På Uncommon Goods har de tack och lov lagt upp en fusklista. Så köp klockan och imponera på din vänner. Pris 25 USD (ca 194 kr).

12 – the cubed root of 1728
1 – Legendre’s constant is a mathematical constant occurring in a formula conjectured by Adrien-Marie Legendre to capture the asymptotic behaviour 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.
5 – The Golden Mean…reworked a little.
6 – Three factorial (3*2*1=6)
7 – Repeating decimal that rounds up to 7.
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
11 An example of Hexadecimal encoding.
