The history of pi dates back to the ancient Babylonians and Egyptians. Babylonians estimated pi as 3.125, and the Egyptians approximated pi to be 3.1605. However, it was the Greek mathematician Archimedes that calculated pi to be between 223/71 and 22/7. A general estimate for pi is 22/7 or 3.14.
In 1706, William Jones was the first to introduce a Greek letter for pi, which was later adopted by the mathematician Euler to represent the ratio between a circle’s circumference to its area. Later mathematicians extended the number of decimal places in this irrational number through rigorous calculations. In the computer age, pi has been estimated to its two-quadrillionth digit.
Some mathematical problems that feature pi are the area of a circle, a circle’s circumference, arc length and the different surface area and volume formulas for a cone, sphere and cylinder. In mathematics, the ratio between a circle’s circumference and diameter is given as pi.

Some interesting stuff on pi, also Albert Einstein’s birthday, according to this article.
Got circles on the brain today? It’s Pi Day — (3/14 for those of us on the west side of the pond) and a celebration of math and science – as well as the infinite and irrational! It is also Albert Einstein’s birthday. What’s Pi? Π is the 16th letter in the Greek alphabet and is used to represent a mathematical constant, the ratio of a circle’s circumference to its diameter, approximately equal to 3.1415…
In basic mathematics, Pi is used to find area and circumference of a circle. You might not use it yourself every day, but Pi is used in most calculations for building and construction, quantum physics, communications, music theory, medical procedures, air travel, and space flight, to name a few.
You might imagine that NASA regularly uses Π to calculate trajectories of spacecraft. Above is a visible documentation of a technique called a “pi transfer” used by the Cassini spacecraft to complete a maneuver to fly by Saturn’s moon Titan flyby.

Yeah, and Nevada and North Dakota can keep theirs too! I’ve had Tennessee’s buttermilk pie and it is actually good. My mother in law used to make it. I believe it is one of those old farm recipes people came up with during hard times. And Kentucky ought to be derby pie, which is my mostest favoritest pie evah!

I do not believe “possum pie.” I had lots of family in AR – “possum pie” was not on the menu. Their deal was those deep, dark chocolate pies.

Gotta say, StrawberryJello Whipped Cream pie sounds good. But Spaghetti Pie is questionable…

I question the Texas selection over Pecan Pie. That don’t seem right. I just had my first piece of buttermilk pie last summer, and I will admit that it’s rather tasty, but not sure I would take that over a piece of heaven. 😉

Agreed! Pecan is the child’s favorite – TX born ‘n bred.
