He mentioned bringing up QM in conversations, so I took a stab at QM pick up lines
OMG, who talks about quantum mechanics in social-situation conversations??? And really, how does THAT work? "Your beauty reminds of Feynmann path integral formulation"? Why does QM have such an intellectual or whatever reputation? Physics has lots of topics, as does advanced mathematics. Other than quirkiness and the potential for philosophical interpreatations, what does QM really have going for it? Note: I took 4 years of QM in school.
"Your beauty reminds me of a tensor product. Now let us couple the wave equation to spin!"
"Baby, my ladder don't go below the ground state! Nor above the uppermost state!"
"You can index my spin states anytime you want!"
"I don't know everything about you and your hamiltonian, so lets approximate you with perturbation theory! How does first order time-independent sound? Giggity giggity giggity!"
"Your discussions about your eyeliner are more boring than sakurai. Heck, you make DJ Griffiths sound interesting!"
"Oh, I will show you quark confinement! strange and charm come and get me"
"I'll show YOU a Stern-Gerlach apparatus!"
"I'm more of a ladies man than Erwin Schrodinger! bow chicka wow wow"
and who can possibly forget
"Hey baby, wanna see my dirac delta function?"
and on we go....
"I'll show YOU a population inversion!"
"planck's constant is really really REALLY small. Kinda like my social confidence actually. well, actually THAT is more like the modified planck's constant, that extra factor of 1 over 2 Pi makes a big difference!"
"What do I think of the Higgs boson? No you go first, hee hee, no you go first, hee hee, no you go first."
"Hey baby, wanna make some dark matter?" [not really QM I don't think]
"I know, I'll all about Schwinger-Dyson-Freeman-Tomonaga!"
"No no no, the proper pick up line is 'you remind of SU(3) x SU(2)' not 'you you remind me of SU(2) x SU(2), thats way too simple!"
and who can possibly forget
"renormalization is basically like saying infinity minus infinity equals zero, which is how attractive I think you are until I start drinking! Woo hoo for beer goggles baby!"
"Come over here and let me probe your Hamiltonian!"
"Your interesting social banter is more theoretically nuanced than an eigenfunction expansion solution for a standard example approximating a physical problem of interest." [Really more E&M than QM I think]
"You know, the infinite square well is like one of maybe 3 QM problems that is actually exactly solvable! And it doesn't even exist in the real world, but is often used as an approximation for physical problems of interest"
