Pi: Not the Movie But the Number

Pi (1998) is a movie I will talk about later.  It was the first feature directed by Darren Aronovsky, who is best known for the intense psychological thriller, Black Swan (2010).  This post is not about the film, but the number.


Pi is a mathematical constant; the ratio of a circle's circumference to its 
diameter.  It is often approximated as 3.14, but it is actually an irrational 
number whose decimal representation never ends and never repeats.
It has been calculated to 5 trilllion decimal places without breaking 
this pattern.  The number is useful in mathematics, science, and engineering.  


Jerry Tuttle, (who gives a calculus based derivation of Pi, π ) in his web article, "Does the Bible say Pi equals three?" discusses this very question.  Some say that there is a mathematical error in the Bible at 1 Kings 7:23.  Remember that one of the recurrent attacks on the Bible is that it is full of "errors."  It is ironic though that the supposed errors can almost always be explained away just as the cities and places which "never existed" keep on being found.
