It took thousands and thousands of years to even move from "round" to "wheel". First they went through "roller" and other stages. library.thinkquest.org And although it is difficult to precisely weigh thoughts, one can be sure that the ideas of some people weigh next too nothing!

Date: 12/17/2003 at 12:57:12 From: Doctor Ian Subject: Re: Theoretical Question about Circumference and Diameter Hi Mark, A lot of people get confused by thinking that pi is something that is determined by actually _measuring_ physical circles. It's not. Pi is the ratio of circumference to diameter for any _mathematical_ circle. But there are no mathematical circles in the real world, so we can't ever find pi by measuring something: Why Pi? http://mathforum.org/library/drmath/view/61017.html Does this help? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/

Take Pi, for instance. It is merely a relationship that exists between the circumference of a circle and the diameter. The relationship is calculated on ideal geometric forms which do not exist in Nature but only conceptually. Therefore, when we measure these aspects of an actual circle (or a wagon wheel) we never get Pi. We always get something else--and we would get something else even if we could measure with 100% accuracy...which we cannot.
