# It’s Pi Day!

OK Matheletes…not PIE day,  but rather Pi, the ratio of a circle’s circumference to its diameter. You know the number that is infinite, that is represented by a symbol….and the numerical representation is normally seen as 3.14.

Now we may never use this in our every day life, but it is part of what modern day life is.  Without Pi there is no geometry, no theory of motion, which means we could have never developed airplanes and space travel. It is used in engineering, science and medicine.

Where would we be without Pi? Well, we could be stuck in a time before the pyramids were built. It dates back about 4000 years and believe it or not according to Wikipedia, the Great Pyramid at Giza, constructed c.2589–2566 BC, was built with a perimeter of 1760 cubits and a height of 280 cubits giving the ratio 1760/280 ≈ 2π.

All the math of how it is used is WAY above my pay grade, so I will leave with something my father taught met that the circumference of a circle was , “Pi R2″ or was it “Pie are squared”? Either way, I remember it and still think that Pie are round?
