Happy Pi Day!

Pie Are Round!

Pie Are Squared!

A very Happy Pi day for everyone. Of course, the ratio of the circumference of a circle to its diameter, \pi, has a long and fascinating history, as can also be found here and here. It allows us to easily do useful things with angles, and hence phases for describing waves and much more.

One of the many formulae for computing \pi (as can be found at Wolfram) is:

\pi = 2\sum_{n=0}^{\infty}\frac{n!}{(2n + 1)!!}

Besides being a very cool formula, that was also an excuse to dip my toes into Latex again. It’s been quite a few years since playing with for publishing, so it feels good to have it here on the WordPress blogging engine.

Getting back to \pi, it seems only fitting that this ancient and venerable number have its own day to be remembered. It also seems only right that this day be 3.14. It also seems only fitting that its day be celebrating by eating, what else, pie! Having illustrated one of the formulae for obtaining \pi, I direct your attention to what could appear to be a most excellent way to obtain pie. The Quantum Pontiff has posted a pie recipe which incredibly includes 2 of the major food groups, chocolate and bacon. Being an experimentalist swayed by primarily by evidence, it seems these experimental results will need to be reproduced.

    Hi Anne,

    As you should be! One LaTex to rule them all! Best formatter ever! Along with pies, being among the best deserts ever and bacon being one of the best pork products ever, and so on…
