# Why is Aronofsky's Pi not Pi?

In Darren Aronofsky's famous and mysterious film "Pi" there are many mathematical secrets. My question is about one of them.

When the film begins one can see the digits of the number Pi. But here something is wrong! The digits of that Pi are not exactly the digits of "real" Pi! Note the following difference:

The Real Pi = 3.14159265 358979323846...

Aronovsky's Pi = 3.14159265 263124534235...

It seems this is not just a simple mistake because "Pi" is a film about mathematics with a strong stress on numbers so every number in it has a particular meaning and probably is a sign for an implicit message. Furthermore many digits of Arnovsky's Pi are true so one who designed the title scene perhaps used a calculator to find exact digits of Pi and then replaced some true digits by fake numbers to produce this "Pi" which is so similar to the real one. Also there is no reason for a mistake in digits after 10th place when you know 9 digits exactly!

Question: What does this difference between the digits of these two "Pi" numbers mean? Is it a message?

• It might be an intermediate result obtained in the process of computing pi using a Taylor series or one of the other infinite series expansions commonly used for computing approximations of pi to a finite number of digits. I'm not sure if they would've gone to that extreme level of mathematical rigor just for the miniscule portion of the audience that might actually investigate this and "get it". – Matt Sep 22 '17 at 0:41
