Many will try to tell you that you've got it all wrong and that π is an irrational number approximately equal to 3.1415926535897932384626433... They may even try to show "proofs" of this using phrases like "infinite summation" and "convergence". Maybe they will try to "show you the light" by drawing circles and showing how to estimate π. Well, it's their argument that is circular! Just remember that the people that fabricated those phrases and arguments are the same that fashioned these vicious lies about π! Imagine: A number whose digits are random and go on forever! Inconceivable!
