Schrödinger's cat wish you all a Happy Halloween!

#26 Fancy Schrödinger's Cat

If you're going to a physics meeting, better be elegant and have a moustache.
This one is for Sara, who has a pretty cool fancy cat (and other fancy animals, like a whale) drawed on her Atomic and Molecular physics notes.

For the unawared: Russell's Teapot

#25 Electron

Even science cats are lazy and gluttonous.

#24 QFT

Quantum field theory. That's all.

#23 Excited energy level

It's so easy to make a cat pass from ground state to an excited state.

#22 Schrödinger's Fat

Poor Dinger, I don't think that's how general relativity works, I think he just ate too much lasagna (was it poisoned?).
