User blog:Catfishperson/Happy Pi Day!

Well, today's Pi day, the most important day of the year!

What if Pi day, you ask? Well for those of you who don't know, Pi (often denoted using the greek letter "π") is an irrational, non-terminating number that somehow finds it's way into lots of mathmatical equations. I being a huge math nerd have memorized the first 121 digits of pi in order. I will now nerd out and go on a rant about how cool pi is.

First, to be an irrational number means to have an infinite number of digits in no evident order whatsoever. To give some idea of the randomness, here are the first hundred digits:

3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679

It will continue on like this to infinity. The 3 first digits are "3.14," this reason that we call March 14th "Pi day."

Again, pi is an irrational number, which means that any number you can think of shows up in it somewhere, you can even find your own birthday in it. My birthday, being 9/10/01 appears in pi as the 291,910'th digit. But it dosen't stop there, literally every single finite number you can possibly think of will eventually show up in pi. That means you could think of some billion digit number, and it would not only show up in pi, but it would show up an infinite number of times. Now really, being an irrational number isn't all that special in itself, if you think about it, there is an infinite number of irrational numbers for every other number. But then you realize that there is already an infinite number of numbers and you get confused. Another well known example of an irrational number is the square root of 2. What really in my mind makes pi special, is that it literally shows up everywhere in math. The diameter of a circle (the line that splits a circle in half) fits into its circumference (the perimeter of a circle) exactly pi times! The radius of a cirlce squared * pi is exactly the area of thr circle. If you take the series "(4/1)-(4/3)+(4/5)-(4/7)+(4/9)-(4/11)...) and continue that process forever, your end result will be exactly pi! If you take the pattern: "3+4/(2*3*4)-4/(4*5*6)+4/(6*7*8)-4/(8*9*10)" and follow it forever, your end result will be pi! Yet this pattern will get you there faster then the 1st pattern! All of trigonometry is pretty much defined off of pi, so it will invariably show up in most trig functions. There are so many more weird examples of pi in math, it literally does show up everywhere.

The 1st 144 digits of pi also strangely add up to 666 (and 144=(6+6)*6+6)).

Although pi is the most recognized constant in the world today, it was first discovered in 1600BC.

Thats all for now. What do you find cool about pi? (Don't even think about saying (low "thug" voice) "Duuuhhhh, Nothing, Duuuuuoooohhhhh")
