Pi is also known as Archimedes' constant (not to be confused with Archimedes' number) and LudolphLudolph van Ceulen ( 28 January 1540 31 December 1610) was a German mathematician who emigrated to the Netherlands. Born in Hildesheim, Germany, he moved to Delft to teach fencing and mathematics. In 1594 he opened a fencing school in Leiden. In 1600 he w's number.
The first sixty-four decimalDecimal also called denary is the base 10 numeral system, which uses the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 (called digits) together with the decimal point and the sign symbols + (plus) and − (minus) to represent numbers. Decimal is the princip digits of π (sequence A000796 in OEIS) are:
More digits of π are also available. See pi to 1,000 places , 10,000 places , 100,000 places , and 1,000,000 places .
Pi is an irrational numberIn mathematics, an irrational number is any real number that is not a rational number, i. one that cannot be written as a fraction a ''b with a and b integers, and b not zero. It can readily be shown that the irrational numbers are precisely those numbers: that is, it cannot be written as the ratio of two integerThe integers consist of the positive natural numbers (1, 2, 3, …) the negative natural numbers (−1, −2, −3,. and the number zero. The set of all integers is usually denoted in mathematics by Z (or Z in blackboard bold, ), which sts. This was proven in 1761Events January 16 British capture Pondicherry, India from the French.

In fact, the number is transcendental, as was proven by Ferdinand von Lindemann in 1882. This means that there is no polynomial with rational (equivalently, integer) coefficients of which π is a root.
An important consequence of the transcendence of π is the fact that it is not constructible. This means that it is impossible to express π using only a finite number of integers, fractions and their square roots. This result establishes the impossibility of squaring the circle: it is impossible to construct, using ruler and compass alone, a square whose area is equal to the area of a given circle. The reason is that the coordinates of all points that can be constructed with ruler and compass are constructible numbers.
While the original Greek letter for pi was phonetically equivalent to the English letter p, it has now evolved to be pronounced like the word pie in most circles.
