Euler’s Sum of Powers Conjecture, Explained

Among other things, Euler was interested in powers of numbers, and in 1769 he made a conjecture now called Euler’s sum of powers conjecture (or just Euler’s Conjecture). In general, a conjecture is a math statement that has not been proven yet, and a theorem is a big result that’s been proven. So Euler was making a sort of educated guess.

Disproving Euler’s Conjecture with a Supercomputer

Euler’s conjecture was disproven in just 2 sentences, almost 200 years later.

  • Sentence 2: This is a counter-example to Euler’s conjecture ok bye³.

The Proof by Counterexample

If a movie was two minutes long, you would call it a ripoff. If a book was two sentences long, you would call that a scam. Can a math proof this short still be legitimate? Yes. Lander and Parkin’s paper is a great example of a proof-by-counterexample.
