Physics in This Episode
- X-ray Diffraction - The episode begins with Leonard entering the apartment in the morning exhausted. He indicates that he was up all night using a free-electron laser for an x-ray diffraction experiment.
- Supergravity - Sheldon indicates that he didn't get his license at sixteen because he was working on supergravity, which is one of various approaches toward a theory of quantum gravity.
- Friction - At the DMV, Sheldon argues about the questions. One asks when the roads are most slippery, and he points out that it's when there's a thin coat of liquid that reduces the coefficient of friction to nearly zero, but not thick enough to introduces a new source of friction.
Sheldon: I just don't see why I need a driver's license? Albert Einstein never had a driver's license.
Howard: Yes, but Albert Einstein didn't make me wet myself at 40 miles an hour.
Penny: And I never wanted to kick Albert Einstein in the nuts.
Penny: You know, I gotta ask, why didn't you just get a license at sixteen, like everybody else?
Sheldon: I was otherwise engaged.
Penny: Doing what? Sheldon: Examining perturbative amplitudes in n=4 supersymmetric theories, leading to a reexamination of the ultraviolet properties of multi-loop n=8 supergravity, using modern twistor theory.
Penny: Well, how about when you were seventeen?
