TED-Ed: The infinite life of pi - Reynaldo Lopes

The video tutorial explains the basic measurements of a circle, such as diameter, radius, and circumference, and introduces pi as the constant ratio of circumference to diameter. It delves into the historical discovery of pi, its nature as an irrational number, and its representation by the Greek letter. The tutorial highlights pi's applications in various scientific fields, including geometry, statistics, and physics, and its role in advanced research like particle physics and cosmology.
