I found a paper giving the solution for the diffusion equation for a conical boundary. Life...

...is very beautiful, and then you die.

It's just one of those truly wonderful things.

For some reason, I never looked for it, or maybe I did, but didn't know how to look for it.

It all came together in a bout of really, really, really bad insomnia.
