Infinite Star of 1,241,100,000,000 never-repeating π fell upon Earth in ancient times and delivers Einstein on 3.14
π is commonly defined as the ratio of a circle's circumference C to its diameter d : pi = C/d
The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi" .
The ratio C/d is constant, regardless of the circle's size. For example, if a circle has twice the diameter of another circle it will also have twice the circumference, preserving the ratio C/d. This definition of p implicitly makes use of flat (Euclidean) geometry; although the notion of a circle can be extended to any curved (non-Euclidean) geometry, these new circles will no longer satisfy the formula p = C/d.

Who discovered Pi?
Greek mathematician Euclid (born 325 BC) Euclidean geometry, attributed by Greek mathematician Euclid (born 325 BC) was the first recorded system used to show Pi as a mathematical constant.
Indian mathematician and astronomer Aryabhata in the 5th century In ancient times, the Indians approximated pi to be about the square root of 10. The Indian mathematician and astronomer Aryabhata in the 5th century gave the approximation of pi = 62832/20000 = 3.1416, which is even more accurate. He did this at the age of 23. He said it is just a constant defined as the circumference to the diameter of circle
It's never ending never repeating no.
The earliest known official or large-scale celebration of Pi Day was organized by Larry Shaw in 1988 at the San Francisco Exploratorium, where Shaw worked as a physicist, with staff and public marching around one of its circular spaces, then consuming fruit pies. The Exploratorium continues to hold Pi Day celebrations. On March 12, 2009, the U.S. House of Representatives passed a non-binding resolution recognizing March 14, 2009 as National Pi Day.
