Fermat's last theorem is one of the most beguiling results in mathematics. In 1637 mathematician Pierre de Fermat wrote into the margin of his maths textbook that he had found a "marvellous proof" for the result, which the margin was too narrow to contain.
If you look at the theorem you can see why Fermat might have thought that he found an elegant proof: the theorem is easy to explain, even to primary school students. But the proof turned out to be elusive even to the most talented mathematicians. It wasn't until over 350 years after Fermat's scribble that Andrew Wiles announced a proof, after years of working in secrecy and using mathematical machinery that goes well beyond the theorem's humble appearance. When Wiles announced the proof at the Isaac Newton Institute in Cambridge the atmosphere, according to eye witnesses, was electric.
This selection of articles and videos explores the theorem, some of the maths used in the proof, Andrew Wiles' monumental effort to find it, and also some other relevant bits of maths. Enjoy!
