Fermat's Last Theorem, a mathematical conundrum that has puzzled scholars for centuries. It is a theorem of such simplicity, yet such profound complexity. A theorem that requires the application of the most advanced mathematical tools, and the simplest of logic.
According to the theorem, the only even perfect square that cannot be represented as the sum of two cubes is 4. That's it. Simple, yet insurmountable.
