3 as the sum of the 3 cubes - Numberphile

TL;DR

Mathematicians search for representations of 3 as a sum of three cubes, revealing complexities and theoretical implications.

Transcript

Well, so a few weeks ago we had a Numberphile video where I reported on the discovery of 42 as a sum of three cubes. (Brady: There it is! I can see it.) Oh yep , yep. So in that video I said that we're gonna have a go at finding a representation for three. We're gonna throw everything that we have at it and we'll see. But, with this kinda thing you... Read More
