His proof of the theorem was never found, so it became know as Fermat’s Last Theorem, which is:
If an integer n is greater than 2, then the equation an + bn = cn has no solutions in non-zero integers a, b, and c.

Simon Singh then wrote an excellent book about it, too, called The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography and Big Bang: The Origin of the Universe. I highly recommend anything he’s written: they’re easy reads for the laymen packed full of anecdotes, history, and explanations.. Singh is a superb science author who has also written
Fermat’s Last Theorem was proven in the 1990s and it ain’t straight-forward. Here’s the original paper (PDF) proving it: The Proof of Fermat’s Last Theorem by R. Taylor and A.Wiles.

The first time I saw this sign the math stunned me. It seemed so obvious and straightforward. I was surprised to not see a designated area to pull-off the side of the road and take a picture like some sort of scenic overlook or historic landmark.

The limit of my games while on long drives was imaging a dirt bike racing along beside us, jumping over ditches and rivers, narrowly missing obstacles on the side of the road. That game only worked when you sat on the right-side of the car.
