HY=EY to you too, buddy

I'm being outsmarted by a personalized license plate (I think)!

I was driving through Durham, NC last Saturday when I saw a truck with a personalized license plate reading HY=EY. The truck also had some math bumper stickers on it. What, if anything does HY=EY mean?

Dunno about the y, unless it's the total quantity, but when H=E, you've converted all enthalpy to energy. "She's givin' ahll she ken giive, Cap'n!"

Maybe it's the Schrodinger equation, with the Y representing psi? See here.

H = Hamiltonian Operator
E = Allowed Energy Levels of a System
Y = Eigenkets of H

And I did some assuming since you can't really use bra-ket on a license plate... sadly.

Seems to be the equation that represents the "Nuclear Many-Bodies" theory. They Y is really Psi (Ψ).

That is the awesomest truck in all of Durham.

Cool license plate, but the really fascinating thing to me is that the equals sign is allowed on license plates(?)! (Not really adding any answers because I'm pretty sure swordfishtrombones nailed it.)

The equal sign could have just been a sticker.

Another vote for Schrodinger equation. Especially when combined with math bumper stickers :)

Living in NC, and having a personalized license plate (GO LINUX), I can attest to the fact that they allow a surprising amount of special characters. When I got my previous plate, it said DOINK! At the time, I experimented to find out that many characters were allowed.

As to what this equation means, I have no idea, but thought I'd throw in this info since people were discussing it.

willc is correct: NC allows tons of special characters. I wish more states did that!

that's awesome!

Alright, so I'm going to go with the Schrodinger equation, despite the glaring omission of a kitty cat bumpersticker. And indeed, it is the awesomest car in Durham. Thanks guys!

Special characters? Wow, could you get Z̡AL҉G̢O?
