  1. In high school, I spent hours trying to find two dice with the same probability as standard dice. My method was just brute force trial and error, writing sums in a 6×6 table. I never did figure it out. Much later I saw that the problem can be solved easily using the factorization of polynomials. Behold the power of math!

  2. Speaking of dice, have you already seen the Mathematician’s Dice on kickstarter.com?

    They have: the imaginary number i; the additive identity 0, the multiplicative identity 1, the golden ratio φ (1.618…); Euler’s number e (2.718…); and the circular constant π (3.141…).
