3.1415926 Reasons To Celebrate PI Day

_{}^{}
1) Pi is one of the coolest (and most
used) mathematical constants there is. It first arrived in written word on
1900-1600BC Babylonian clay tablets, where pi was estimated to be 23/8≈3.1250.
Pi(π) is defined as the ratio of a
circles circumference C to its diameter d. This means that no matter the size
of the circle the ratio will never change. However, this definition is only
valid in 2-dimensional Euclidean geometry. A second definition was created to
describe pi in a more universal manner, pi is twice the smallest positive x for
which cos(x)=0.
Pi is an irrational number, meaning it
can never be written as the ratio of two integers. The most commonly known
fractional equivalent of pi, 22/7, is only accurate to two decimal places of
the actual pi value. Since pi is irrational, it has an infinite number of
digits in its decimal state, and will never end in a repeating pattern of
numbers.
Pi is a transcendental number. Pi as a
number is not algebraic, it cannot be the root of a non-zero polynomial
equation with rational coefficients.
The digits of pi actually pass
statistical randomness tests, there is no pattern whatsoever.
2) Geeks and nerds the world around
have iconized this mathematical symbol to the point of cultdom. Pi has been
immortalized on t-shirts, jewelry, through parades, secret handshakes, inside
jokes, Google doodles, college pep rally chants, and memorization competitions.
There are likely as many versions of
geeky pi t-shirts as there are digits in pi itself (see caption above).
Did you know that San Francisco holds
a Pi Day parade every March the 14th? This parade will have 500 digits... I
mean people marching down the Embarcadero to the Pi Shrine. The Pi Shrine is a
one foot diameter gold plate engraved with the first 108 digits of pi.
When you are out and about on Pi Day,
give someone a "High Pi" instead of a high five. It's similar to a
high five, but uses only three fingers instead of five.
If you ever attended or dream of
attending the Massachusetts Institute of Technology (MIT), you will likely
learn cheers that are a bit different from those that other schools learn.

*E to the U - from the MIT Cheerleading
Book*
*I'm a Beaver, you're a Beaver, we are
Beavers all.*
*And when we get together, we do the
Beaver call.*
*E to the U du dx,*
*E to the X dx.*
*Cosine, secant, tangent, sine,
3.14159.*
*Integral radical mu dv*
*Slipstick, sliderule, MIT.*
*Go Tech!*
3) You are encouraged to eat pi in all
of its forms: fruit pie, meat pie, pizza pie, creme pie, egg pie.... you get
the idea, Eat PIE! There is a pie for everyone!
