In honor of International Pi Day (which is also, conincidentally, my birthday), here's a song about the virtues of pi by Alan Ferrier and Antoni Chan.
This is not a diary. It is a collection of thoughts, essays, stories, etc on those topics that are of interest to me. Being a blog, it goes without saying that it is utterly self-indulgent.

Frosty the photon
Escaped from a black hole,
Then he used his spin
To find his kin,
Near the ends of a dipole.
Frosty the photon
With momentum h-bar-k
Though he had the right
To be known as light,
He was called a gamma ray.
