Why is no one taught the one concept in quantum physics which denies reality?

Should I have breakfast before I read this.

>Scientific realism is the belief that the true nature of reality is the subject of scientific investigation

Some pointless repetition there, if you ask me. Reality is usually taken to mean “the true nature” of whatever’s being investigated.

So he’s saying “the true nature of the true nature” is the subject of scientific investigation.

Anyway I’ll read the rest after my shower.

You are a remarkably foresightful person.

That or you have already read it.

>There is no way to define a reality that is independent of the way we choose to look at it.

Doesn’t sound terribly significant to me, unless your expectations are misplaced.

Realism is what we hope to achieve in a demonstrably accurate model (indeed that’s what we mean by the term “realism”).

The “world itself” doesn’t need to be realistic, because it’s not modelling anything.

Je ne savais rien de le tuyau de René Magritte.

Good summary, but could someone translate:
“This stochasticity is however epistemic and not ontic as in the standard formulation of quantum mechanics.”
for me?

It’s not very good.

Mostly. But there is an application.

There is one interpretation of quantum mechanics in which context is all-important. It’s like the many-worlds theory, but instead of the universe branching into multiple realities at the observation of a quantum variable, the observation is deterministic based on the context. The context being “the name for the fact that any real states of the world giving rise to the rules of quantum physics must depend on contexts that no experiment can distinguish”.

Or to put it another way, in this interpretation of quantum mechanics, no experiment is ever repeatable because the external context changes.

Does that qualify as unpopular?
