OBSERVATION (big errors)

There are two big errors the unmalicious can commit:
1. Attending to theory instead of to urgent practicalities. (‘doing math in the cockpit’)
2. Partying instead of attending to theory.
Ludwig Wittgenstein famously noted error #1 (studying to become professional philosophers while war was raging)
Then there is the one error that the malicious commit: partying instead of attending to urgent practicalities. (‘fiddling while Rome burns’)

theorems whose proofs involve a parity argument

Here are some such:

1. Euler, in his proof that all even perfect numbers have the form given by Euclid, used a very slick parity (odd/even) argument.

2. Parity is crucial in the canonical solution to the problem of generating Pythagorean triples.

3. By a parity argument, it is proved that the number of sides of a golygon is a multiple of 8.

JOKE (Columbus)

Why Columbus wound up landing at a random island in the Caribbean instead of somewhere on the New England coast: He neglected to fully charge his GPS system before he left.
