Sheldon notices that someone has touched his board and changed some equations. He’s quite furious about it.
Sheldon: Someone touched my board. Oh God, my board. Leonard! Leonard!
Leonard (entering): Hey, what’s the matter?
Sheldon: My equations, someone’s tampered with my equations.
Leonard: Are you sure?
Sheldon: Of course I’m sure. Look at the beta-function of quantum chronodynamics, the sign’s been changed.
Leonard: Oh yeah. But doesn’t that fix the problem you’ve been having?
Sheldon: Are you insane? Are you out of your mind? Are you…. hey look, that fixes the problem I’ve been having.
Lesley (entering): You’re welcome.
Sheldon: You did this?
Lesley: Yeah, I noticed it when I got up to get a glass of water, so I fixed it, now you can show that quarks are asymptotically free at high energies. Pretty cool, huh?
Lesley: Listen, I got to hit the lab. Thanks for a great night.
equation = a mathematical statement in which you show that two amounts are equal using mathematical symbols
to tamper with something = to touch or make changes to something that you should not, usually without enough knowledge of how it works
quantum chromodynamics = According to Wikipedia, it is a theory of the strong interaction between quarks.
quark = one of the most basic forms of matter that make up the heavier elementary particles
You’re welcome = said as a polite answer when someone thanks you for doing something
asymptotic = It means approaching ever nearer but never reaching it completely.
to hit = In this case it means to arrive at a place
lab = short for laboratory
