This article gives a brief history of the analysis and computation of the mathematical constant $\pi = 3.14159 \ldots$, including a number of the formulas that have been used to compute $\pi$ through the ages. Recent developments in this area are then discussed in some detail, including the recent computation of $\pi$ to over six billion decimal digits using high-order convergent algorithms, and a newly discovered scheme that permits arbitrary individual hexadecimal digits of $\pi$ to be…

It is shown that computing a bit of a fixed real algebraic number is in C= NC1 $\subseteq \mbox{{\sf L}}$ when the bit position has a verbose (unary) representation and in the counting hierarchy when it has a succinct (binary) representation.

A History of Pi
The history of pi, says the author, is a mirror of the history of man, and Petr Beckmann holds up this mirror, giving the background of the times when pi made progress -- and also when it did not, because science was being stifled by militarism or religious fanaticism.
