Pi Day Inspires NASA's Mathematical Marvels and Diversity Advocacy.

NASA's Jet Propulsion Laboratory celebrates Pi Day with a set of math problems involving real space missions. The annual NASA Pi Day Challenge offers four math problems involving real NASA missions and science, allowing students to put their math skills to the test. Pi is a mathematical constant that represents the ratio of the circumference of a circle to its diameter and is used in many fields, including mathematics, physics, engineering, and statistics.
