Hello, I'm an expert in mathematics and history of mathematical concepts. Let's delve into the origins of the name for the mathematical constant π.

The constant π, known as "pi," is a mathematical constant representing the ratio of a circle's circumference to its diameter in Euclidean geometry. The symbol π was first used by the Welsh mathematician William Jones in 1706. However, it was popularized by the Swiss mathematician Leonhard Euler in the early 18th century.

The name "pi" is derived from the Greek word "peira," which means "to encircle." This is a reference to the fact that pi is the ratio of the circumference of a circle to its diameter. The first letter of the Greek word "peira" is "π" (pi), which is why this letter was chosen to represent the constant.
