It it considered that the first proposal of using symboll "pi"  as the ratio of the circumference of a circle to its diameter was firstly appeared in the works of William Jones. But he was  a Welsh mathematician, not Swiss.\n\nFrom section "History of the notation" of first attached wiki article:\nThe symbol "π" for Archimedes' constant was first introduced in 1706 by William Jones when he published A New Introduction to Mathematics, although the same symbol had been used earlier to indicate the circumference of a circle. The notation became standard after it was adopted by Leonhard Euler.

The use of the Greek letter π for this constant is derived from Greek words like περιφέρεια (for periphery) and περίμετρον (for perimeter) starting with this letter. The name of the Greek letter π is pi, and this spelling is used in typographical contexts where the Greek letter is not available or where its usage could be problematic. When referring to this constant, the symbol π is always pronounced like "pie" in English, the conventional English pronunciation of the letter.

I do believe it is Pi....\n\n(NOTE: The below information was gleaned from an article in The New Yorker magazine, March 2, 1992, called "Profiles: The Mountains of Pi")\n\nPhysicists have noted the ubiquity of pi in nature. Pi is obvious in the disks of the moon and the sun. The double helix of DNA revolves around pi. Pi hides in the rainbow, and sits in the pupil of the eye, and when a raindrop falls into water pi emerges in the spreading rings. Pi can be found in waves and ripples and spectra of all kinds, and therefore pi occurs in colors and music. Pi has lately turned up in superstrings.\n\nPi occurs naturally in tables of death, in what is known as a Gaussian distribution of deaths in a population; that is, when a person dies, the event "feels" pi. It is one of the great mysteries why nature seems to know mathematics.

Aryabhata was both a mathematician and an astronomer.  Since your question primarily deals with mathematics, I will attempt to answer that question.\n\nAryabhata was one of the first mathematicians to theorize that the number pi was an irrational number.  Specifically, he estimated pi to be approaching the value of 62832/20000, or 3.1416.  With his writings translated, it has been assumed that his use of the word "approaching" may indicate that it is not only an approximation of the value of pi, but that pi is a non-repeating number that cannot be solved, therefore an irrational number.\n\nThe significance of this is that Aryabhata lived from approximately 476-550 AD.  The irrationality of pi was not proved until 1761 in Europe, making his insight quite substantial to the mathematical community.

Do you mean math concept?\nMarch 14 was Pi day.\nMarch 14 is 3/14.\nPi is approximately 3.14

The mathematical constant π is a real number which is defined as the ratio of a circle's circumference (Greek περιφέρεια, periphery) to its diameter in Euclidean geometry, and which is in common use in mathematics, physics, and engineering. The name of the Greek letter π is pi (pronounced pie in English), and this spelling can be used in typographical contexts where the Greek letter is not available. π is also known as Archimedes's constant (not to be confused with Archimedes's number) and Ludolph's number.

Pi is the result of dividing the diameter of a circle by its circunference.

Up to 1000 AD, π was known to less than 10 decimal digits only:\n\nAs early as the 19th century BC, Babylonian mathematicians were using π=25/8, which is within 0.5% of the exact value.\n\nAn Egyptian scribe named Ahmes wrote the oldest known text to give an approximate value for π. The Rhind Mathematical Papyrus dates from the Egyptian Second Intermediate Period—though Ahmes stated that he copied a Middle Kingdom papyrus (i.e. from before 1650 BC) —and describes the value in such a way that the result obtained comes out to 256 divided by 81 or 3.160.\n\nThe Indian astronomer Yajnavalkya gave astronomical calculations in the Shatapatha Brahmana (c. 9th century BC) that led to an approximation of π = 339/108 = 3.1389, which is correct to 2 decimal places when rounded.\n\nThe Chinese mathematician Liu Hui in AD 263 computed π to 3.141014, which is correct to 3 decimal places, though he suggested that 3.14 was a good enough approximation.\n\n\nGet more form the links below

Carl Friedrich Gauss (30 April 1777 – 23 February 1855) was a German mathematician and scientist of profound genius who contributed significantly to many fields, including number theory, analysis, differential geometry, geodesy, magnetism, astronomy and optics. Sometimes known as "the prince of mathematicians", Gauss had a remarkable influence in many fields of mathematics and science and is ranked beside Euler, Newton and Archimedes as one of history's greatest mathematicians.

The value of pi is a constant which equals the circumference of a perfect circle divided by its diameter. It is a transcendental number, meaning that the number of decimals is infinite, yet all the numbers are defined. Pi holds a certain mystique to it, as it shows up in all kinds of math equations.\n\nYou may recognize its value as 3.1415926535897932384...\n\nPi was simply the Greek symbol chosen to represent this value.

Pi is the ratio of the circumference of a circle to its diameter. To put it another way, it's the length of the circumference divided by the length of the diameter.\n\nPi always works out to be the same value, no matter what size the circle is. So Pi is a Big Deal because it lets you easily measure the length of the curved line that makes up a circle.\n\nPi = C/D, so if you know the diameter and Pi, you can calculate the circumference.\n\nIF you do the math, and divide the circumference by the diameter, you'll get 3.14159265358979323846264338327950288419716939937510.....\n-- where the dots represent the fact that no matter how long you keep dividing, it never comes out even and the pattern of numbers doesn't repeat. It has reportedly been calculated out to 206 billion digits!!\n\nThere are charts that describe the history of Pi, which goes back to the Babylonians (2000 BC), and how accurately (or inaccurately) Pi has been calculated through the years. I'm sorry I can't make it appear in neat columns here, but you can see it neatly if you go to external link\n\nEven though the rough value of Pi was known long before his time, the first theoretical calculation seems to have been carried out by Archimedes of Syracuse (287-212 BC).

Say hola to Bernhard Riemann. The man who paved the way for relativity also developed the symbol for congruence!
