physika reacted to jim mcnamara's post in the thread Undergrad Is GRW theory an interpretation of quantum mechanics or a rival theory? with Like.
Ontic comes from philosophical ontology. The meaning in that context: ontic is physical, real, or factual existence. So it's use in...

Do you have a reference for those assertions? Even if they won't ask you, there are definitions by Tarski from 1933 and 1956 for...

physika reacted to Paul Colby's post in the thread Is the quantum wave function a real object or a mathematical tool? with Like.
An element of reality isn’t an object either, right? Physics is a human activity. Humans use tools to do physics. These tools include...

Hum, is the number 3 a real object? I would say no but that’s just me.

physika reacted to Dale's post in the thread Graduate How valid is the Block Universe theory? with Like.
Lorentz aether makes no distinct experimental predictions from special relativity. Therefore it is an interpretation, not a distinct...

I always feel that the overemphasis on “observers” can naturally lead to this kind of a misunderstanding.
