### Math identification

Hello!

So... I have this shirt.

I like this shirt. A lot. However, I feel kind of like a dick for wearing it without knowing what mathematics it actually depicts. I'd like some help identifying it and hell, possibly understanding it.

Here's a better shot of the text:

The standard joke is that those are Maxwell's equations, which describe (among other things) the behavior of light. In this case for some godawful reason or another they appear to be in spherical coordinates. Probably to make it look more intimidating.

That's my guess anyway. Honestly I don't feel like converting Maxwell's equations to spherical coordinates to check.

### Re: Math identification

So the shirt is a way of pissing off people who actually know what it is about, and/or making me look like a dick?

Why thank you, Department of Education of Western Australia! <3

[although I suppose it makes sense for light to be interacting with a sphere if we're discussing Earth]

Those are Maxwell's equations in spherical coordinates. It's not pissing off anybody who knows what's going on, it's just written inelegantly to make it look cool. It's actually kind of cool as a Maxwell's equations describe, in particular, the behaviour of light. I'd chuckle gregariously if I saw you wearing that; I wouldn't be the least bit offended.

I can testify that would have pissed off my differential calculus professor, who hated tying down structures with coordinates. Indeed, he even criticized my more ordinary shirt with the divergence and curl notations, because he preferred some two-equation formulation of it. I've managed to repress the memory, but they both contained notation that I haven't seen before or since (one of them may have been the D'Alembert operator), and so the elegance was quite lost on me.

Maxwell's equations take five symbols to write down if you do it properly.

At the risk of being dreadfully off topic, you're rather handsome. Damn you.

I thought the same thing! (Not to be homosexual. You're just a good looking guy.)

I'd let you look after my teenage daughter that I don't have. But you have a bit of the 'Cedric Diggory' to your look. I'd worry you'd bite her or something. *hides*
Anything I said pre-2014 that you want to quote me on, just run it past me to check I still agree with myself.

Interestingly, my first thought was that if twilight didn't suck that is what edward would look like.
