Funny story
Years and years ago, at 1637 , the mathematician Ferme wrote in the sides of a math book he was reading he found a "wonderfully simple proof for this, but this edge doesn't have the room for it". Ferme then died, i guess without writing the whole thing as it was never found.
It took 350 years to prove this and it spans 200 pages of math so complex it surpasses what most 1st degree in mathematics students know at the end of their degree.
People are still looking for the "exceedingly simple" solution but the popular theory is that
a) he made a mistake
b) he did a little trollin
