Quote for the day,

"It can be of no practical use to know that pi(the ratio between the diagonal and circumference of a circle) is irrational, but if we can know, it surely would be intolerable not to know." - E.C. Titchmarsh

Mathematical scientists only need to know pi from 16 to 32 decimal places - at least, so far. Computer engineers like to test their latest computers by determining pi(and other mathematical things like factoring digits, e, and others) to ever greater decimal points.  The current record holder is around 11 trillion decimal points! Well, I guess scientists have a long ways to go before they can require as many decimal points as are now available to them!
