So sure, non-malativistic quantum mechanics is not fundamental physics.
Yeah.
Guess what?
Quantum electrodynamics is also not fundamental physics.
It's an effective field theory that's applicable at energies below the electroweak symmetry breaking scale.
So are there fundamentally any electrons?
No.
Um
Uh is QED a fundamental theory?
No, it nothing studies is fundamental.
Nothing the standard model studies is fundamental, really.
I mean it's an effective field theory again that's descriptive below Planck scales.
We don't actually have any empirically confirmed fundamental theories.
Yeah, fundamentality is an aspiration.
But we're selling physics short if we think the only thing physics is telling us about is fundamental stuff.
So what is fundamental physics then?
Well, the way people often use fundamental physics is much broader than that.
And um I think it's semi sociological what they mean by it, but some in in there's some sense of fundamental
where fundamental applies to say atomic physics, um
maybe even applies to like classical Hamiltonian mechanics, the context in which you might say the classical electromagnetism is fundamental physics, but climate science isn't fundamental physics.
