Schrödinger's Cat: A cat, along with a flask containing a poison and a radioactive source, is placed in a sealed box shielded against environmentally induced quantum decoherence. If an internal Geiger counter detects radiation, the flask is shattered, releasing the poison that kills the cat. The Copenhagen interpretation of quantum mechanics implies that after a while, the cat is simultaneously alive and dead. Yet, when we look in the box, we see the cat either alive or dead, not both alive and dead.
Larry Gopnik: So, uh, what can I do for you?
Clive Park: Uh, Dr. Gopnik, I believe the results of physics mid-term were unjust.
Larry Gopnik: Uh-huh, how so?
Clive Park: I received an unsatisfactory grade. In fact: F, the failing grade.
Larry Gopnik: Uh, yes. You failed the mid-term. That's accurate.
Clive Park: Yes, but this is not just. I was unaware to be examined on the mathematics.
Larry Gopnik: Well, you can't do physics without mathematics, really, can you?
Clive Park: If I receive failing grade I lose my scholarship, and feel shame. I understand the physics. I understand the dead cat.
Larry Gopnik: You understand the dead cat? But... you... you can't really understand the physics without understanding the math. The math tells how it really works. That's the real thing; the stories I give you in class are just illustrative; they're like, fables, say, to help give you a picture. An imperfect model. I mean - even I don't understand the dead cat. The math is how it really works.
Clive Park: Very difficult... very difficult...
Rabbi Marshak: When the truth is found. To be lies.
[the rabbi clears his throat]
Rabbi Marshak: And all the hope. Within you dies. Then what?
[the rabbi clears his throat again]
Rabbi Marshak: ...something. These are the members of the Airplane. Interesting. Here.
[He gives Danny back his radio]
Rabbi Marshak: Be a good boy.
这是男孩被犹太老师没收的收音机里的那首Jefferson Airplane乐队的《Somebody To Love》。这首歌是这样说的:
When the truth is found to be lies
and all the joy within you dies
don't you want somebody to love
don't you need somebody to love
wouldn't you love somebody to love
you better find somebody to love
