Fermat’s Last Theorem – The Movie And Book

Pierre de Fermat wrote:

I have a truly marvelous proof of this proposition which this margin is too narrow to contain.

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 directed a documentary about the subject:

Simon Singh then wrote an excellent book about it, too, called Fermat’s Enigma. Singh is a superb science author who has also written 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.

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.

I got 735 on first try, 425 on second.

It’s A Sign

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. There should have been a line of cars observing this unique oddity.

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.
