What Is Pi (π)? Is It Infinite?

The video explores the significance of the Pi symbol in mathematics and its impact on human history. It discusses the discovery of Pi as a constant ratio of a circle's circumference to its diameter, first named by William Jones. Pi is an irrational and transcendental number, meaning its decimal expansion is infinite and non-repeating. Various methods have been developed to calculate Pi, with NASA using around 40 digits for scientific purposes. Pi's influence extends to modern technology, including quantum computing, and it is celebrated annually on Pi Day. The video highlights Pi's fundamental role in mathematics and its ongoing journey of discovery.
