Is Mathematics true?  It sounds a ridiculous question, but I will show
a few examples (some of which include the digits of pi) which show
that the matter deserves discussion. There is a lot of history behind
it.

Mathematics is all good, bad and useful.  Everybody could come up with
examples. I'll challenge the audience to provide some and show some myself.

Mathematics is beautiful.  I believe that its beauty is easy to see and
will try to convince the audience.

The digits of PI arise in many likely and unlikely places. I will show
this (I have a movie) and try to explain why this is so.

Finally, I will show "the most beautiful" equation of all (the Boltzmann
equation) and talk about what is has to do with the arrow of time.
