Hey, why did you make this two videos and not just one?
Because two videos would have been very long and deterred casual viewers from even learning about the problem.
Makes more sense to make a video which describes the problem and the solution, plus its history and the fact a one sentence proof exists... then have a more technical second video for people who want to see the proof itself. I have made links to the second video as clear as possible and I suspect more technical fans subscribe to Numberphile2 anyway.
Correction: At 4:08 the number at the bottom should be the prime 23, not 22...
