* Definition of pi: Pi is the 16th letter in the Greek alphabet. It is equal to 3.141592 when shortened, but never ends.

* Archimedes-One of the major contributions Archimedes made to mathematics was his method for approximating the value of pi. It had long been recognized that the ratio of the circumference of a circle to its diameter was constant, and a number of approximations had been given up to that point in time. Archimedes was the first person to calculate the value of pi.

* Ptolemy- Ptolemy was an observer and mathematician who had written on astronomical topics such as conjunctions. He devised proofs and theorems in which he was able to evaluate pi. His calculations were pi= 3+17/120=3.14166.

* William Jones- Jones was a mathematician, known for his proposal for the use of the symbol π for pi to represent the ratio of the circumference of a circle to its diameter.

* PI Jokes
Question: What do you get if you divide the circumference of a jack-o-lantern by its diameter? Answer: Pumpkin Pi!
Q: What was Sir Isaac Newton's favorite dessert? A: Apple pi!

Mathematician: Pi r squared
Baker: No! Pie are round, cakes are square!

* A transcendental number is a number that is not the root of any integer polynomial, meaning that it is not an algebraic number of any degree. Every real transcendental number must also be irrational, since a rational number is, by definition, an algebraic number of degree one. Ferdinand von Lindeman first called pi a transcendental number

* Irrational number is a real number that cannot be expressed as a rational number. In 1761 Lambert proved that Pi was irrational, that it can't be written as a ratio of integer numbers.

...π (sometimes written pi) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. It is approximately equal to 3.141593 in the usual decimal notation (see the table for its representation in some other bases). The constant is also known as Archimedes Constant, although this name is rather uncommon in modern, western, English-speaking...

...The History of Pi
Throughout the history of mathematics, one of the most enduring challenges has been the calculation of the ratio between a circle's circumference and diameter, which has come to be known by the Greek letter pi. From ancient Babylonia to the Middle Ages in Europe to the present day of supercomputers, mathematicians have been striving to calculate the mysterious number. They have searched for exact fractions, formulas, and, more...

The History of Pi
Most individuals who have a general mathematical education that touches on the basics of geometry commonly know pi. The definition of pi is the ratio of the circumference to the diameter of the circle (Smoller, 2001). The majority of the population, however, does not realize the history associated with the symbol, which not only spans throughout the centuries but throughout the millenniums. The...

...History of Pi
There are many people who have discovered and proved what pi is. As time goes on people discover more and more of the seemingly random numbers. Four of the people who proved pi are the Liu Hui, Archimedes of Syracuse, James Gregory, and the Bible.
The first proof I will be talking about is Liu Hui’s. Liu Hui was a Chinese mathematician whose method for proving pi was to find the area of a polygon inscribed in a...

...Pi is an ancient and wonderful Number to the World of Mathematics invented with the Geometrical structure Circle.
CIRCLE
It is felt that the creation of the Circle is not created by the man himself but came through the inspiration of Nature itself. The shape of Sun, Full Moon, Eyes are some examples for it.
Some basic things :
There are 3 major parts to remember.
Radius : The straight line drawn to the Circumference of the...

...Pi has always been an interesting concept to me. A number that is infinitely being calculated seems almost unbelievable. This number has perplexed many for years and years, yet it is such an essential part of many peoples lives. It has become such a popular phenomenon that there is even a day named after it, March 14th (3/14) of every year! It is used to find the area or perimeter of circles, and used in our every day lives. Pi is used...
