I was going to post this question yesterday when Microsoft took over my computer then I had to leave. Then conversation revolved
around its content in one way or another so I’ll try again-

“If you like numbers, you will love March 14, 2015. When written as a numerical date, it’s 3/14/15, corresponding to the first five digits of pi (3.1415) -- a once-in-a-century coincidence! Pi is useful for all kinds of calculations involving the volume and surface area of spheres, as well as for determining the rotations of circular objects such as wheels. That’s why pi is important for scientists who work with planetary bodies and the spacecraft that visit them. At NASA's Jet Propulsion Laboratory, pi makes a frequent appearance.

Many aspects of this APOD show the importance of those who, over history, strove to understand and use pi’s relevance.
