Why does pie go on forever? Why is it called pie?
Pi is an irrational number. That means it can't be represented as a simple decimal. It keeps going on.

The mathematical value known as "pi" (written as π) represents the ratio of a circle's circumference to its diameter. Pi is an irrational number, meaning it cannot be expressed as a finite decimal or a fraction. It goes on forever and has been calculated to billions of digits after the decimal point without any repeating pattern.
The reason pi goes on forever is because it is fundamentally linked to the concept of a circle, which is a continuous and infinitely detailed geometrical shape. No matter how many digits of pi you calculate, it will never truly end because the relationship between a circle's circumference and diameter can be infinitely divided.
As for why it is called "pi," the name originates from the Greek letter π (pronounced "pi"), which is the first letter of the Greek word "perimetros." The Greek mathematician William Jones introduced this symbol in the early 18th century to represent the ratio between a circle's circumference and diameter. Over time, it became widely adopted and is now recognized as the symbol for this mathematical constant.
To calculate pi, mathematicians have developed various algorithms and formulas that can approximate its value to any desired level of precision. Many people find it fascinating to explore the endless digits of pi, and its calculation has become a popular challenge and competition among mathematicians and computer enthusiasts.
