aint that linear alge
QM is just linear Algebra spiced with physics.
Yea but the wave function in the time independent Schrödinger equation is the eigenfunction of the energy which is an eigenvalue
'eigen' is already the weirdest prefix. Trust nothing with it.
Half of it is like they couldn’t get the math to work out with their theory, so they made up some bullshit to make it work.
“Oh, the math for string theory doesn’t work out? Clearly there must be 12 more spatial dimensions.”
And quantum entanglement is just bullshit as Schrodinger's Cat points out.
Nothing exists in a closed system. If anything is entangled, everything would have to be entangled, making it useless. Many-worlds is the only theory that at least makes some sense of it. The cat isn't both alive and dead, but rather there is a universe where the cat is alive and a universe where the cat is dead, which isn't really entanglement as the universe we're in is always resolved one way or the other. But even that is basically "oh we can't make sense of this? Clearly there must be infinite universes".
String theory =/= quantum mechanics. String theory does include some weird theorised stuff.
Quantum mechanics itself is, unfortunately or otherwise, a proved model and makes extremely accurate predictions at a particle level. It is not just made up bullshit.
Then when you get to grad school you find out that quantum mechanics is the baby version of quantum field theory
to me, grad school, always sounded like going millions of dollars into debt for a small chance at a $200,000 year job where you die of stress after 5 years of working. Now, I'm not very good at math, but
that’s true for lucrative fields. Physics isn’t particularly lucrative. Physics grad students are typically paid a small stipend to attend as research assistants.
The real issue is that these positions are extremely underpaid, and postdocs have it even worse
