I would be up for buying a T or Hoodie with some key equations on them eg;

1. creation/annihilation operators

2. Maxwell's equations in differential form with the title something like "god said <equations> and there was light"

3. SWE

4. HUP

Interesting! Can you expand on 1,3,4?

I am not very witty but I was thinking the equation and some meme quality phrase to go with it.

really a tribal identification thing like how we used to find our own kind in a crowd by what band T-shirt they had on.

The photon creation operator is $a^\dagger$, right?

$a^\dagger|0>=|1>$
A lightbulb moment.

Nice. But the dagger should be a superscript, I think. I'd double check the maths with someone who is current on QM before putting it into production, too. It's been about 20 years since I did anything in that field...

It has to be superscript. The state should use \rangle: $\rangle$, not >. Also \mid, $\mid$, not |

$a^\dagger \mid \! 0 \rangle = \mid \! 1 \rangle$
