ABSTRACT:
The desire to understand π, the
challenge, and originally the need, to calculate ever more accurate
values of π, the ratio of the circumference of a circle to its
diameter, has captured mathematicians  great and less great 
for many many centuries. And, especially recently, π has
provided compelling examples of computational mathematics.
Pi, uniquely in mathematics, is pervasive in popular culture and
the popular imagination. In this lecture I shall intersperse a
largely chronological account of π's mathematical and numerical
status with examples of its ubiquity.
The talk is lodged at
