The Arithmetic Game is a fast-paced speed drill where you are given two minutes to solve as many arithmetic problems as you can.

A very nerdy talk on baseball using analogies to logic and probability.

A twin prime is a prime number p such that either p+2 or p-2 is also prime. For example, 11 and 13 are a pair of twin primes. The twin primes conjecture posits that there are infinitely many such pairs, but as of 2024 this conjecture remains unproven. This combo creates a board state where the outcome hinges on this unsolved math problem.
