5/3/17 - All Lies

Today I learned:

  • Most of what I learned in Mathematics at the earlier levels are all lies or half-truths.

    Learned about pairwise coprimes and Euler’s Totient and relative primes.

  • vacuous truth - “A vacuous truth is a statement that all members of the empty set have a certain property.”

    One of the things they wanted us to try was a derivation of the Nim game. You can win if you start first and make sure the Nim-sum is zero to win. The goal is to be the last person to pick up a number of pencils that is either 1, 2 or 3.

    As you can see -> my sweat and tears

    Took me a while to figure it out. First I thought it was just keeping the numbers not a multiple of three, then I thought I should just mirror the move of my opponent. This is one of those games where it really does have an advantage to start first. See Impartial games.
