Bessel functions

By Marcus Wilson 10/03/2011 2

I vaguely remember the following conversation from back when I was a PhD student.

Student A: What’s a Bessel function?

Student B (waving his arms about): It’s a wavy thing – goes like this, doesn’t it?

Student A: But what IS it?

Me: Something to do with waves on a membrane, isn’t it?

Student A: Does it have a formula?

Me and student B: Don’t know…
