Quantum Leap1989

Lee Harvey Oswald:
[looking at Sam's reflection in the mirror] I still don't get how you do this.

Admiral Al Calavicci:
Well, i-i-it is a little difficult to explain.

Lee Harvey Oswald:
You think I'm too stupid to understand?

Admiral Al Calavicci:
Well, nobody understands it except Dr. Beckett.

Lee Harvey Oswald:
Try me.

Admiral Al Calavicci:
Try you. Okay. Let's start with the string theory. What's the string theory?

Lee Harvey Oswald:
String theory?

Lee Harvey Oswald:
[in Sam's voice] It helped close the conceptual gulf between relativity and quantum mechanics. It postulates that subatomic particles are not points, but strings, about one Planck-length long. The rate at which strings vibrate can generate the properties of all known particles.

Lee Harvey Oswald:
[in his own voice] Hmm? How did I know that?
