I meant to say a "non-repeating decimal". But it can be expressed accurately as a ratio rather than as 3.1459,etc.
The film "Pi" was based on a theory by two groups, an assortment of Talmudic rabbi scholars, and an assortment of stock analysts, that pi was, in fact three plus a repeating decimal, and when the actual enormously long decimal fraction was known, then (a) the gyrations of the stock market would be made predictable, and (b) a message from God woulf be revealed.
This assertion in the plot is a bit preposterous, but it is still a very clever film. The protagonist is a Jewish mathematical genius who builds computers and writes programs to discover the value of Pi, and he runs up against these two warring factions. He also suffers from horrible migraine headaches.
It was made in balck and white, and of course, matematics was greatly emphasized, so it did not triumph at the ticket booths, but it was entertaining. I imagine Kimba would love it.
Probably available from Amazon on DVD for a pittance.
