For some time I've been wondering how to eloquently distinguish classical and quantum physics. What I mean by eloquent is both simple and short. By simple I mean understandable to any college freshman, and with that caveat, as short as possible.(adsbygoogle = window.adsbygoogle || []).push({});

Something like: "quantum has inherent randomness classical doesn't", I don't think works because "inherent randomness" isn't simple and I'm not even convinced the statement is valid. It is short.

"Quantum violates Bell's inequality classical doesn't." could possibly be made simple , but then no longer short.

What about: "In classical, outcomes depend on the past, in quantum they don't" I'm not sure it's true, does this need freewill? (Conway-Kochen) Is "outcome" simple? Probably.

I've been toying with:

Alice and Bob are too far apart to communicate and neither knows what the other is doing.

If Alice and Bob both perform experiment X they will get the same result.

Alice performs X and gets result 1, while Bob performs Y and gets 2.

If Bob had performed X instead would he have necessarily gotten 1?

Yes is classical, no is quantum.

It's xmas time can I get some help from the wisemen?
