This video severely disrupted my sleep yesterday. Whole night I was thinking and dreaming about this darned thing, even though I knew it was pretty pointless to do so, considering I'm not even a mathematician and have always found maths hard. Still a brilliant video and now I get why people could spend 20+ years of their precious lives trying to solve these things.
