bhobba replied to the thread Is the quantum wave function a real object or a mathematical tool?.When speaking about reality as a concept, I like to keep in mind the first few chapters of Feynman's Lectures. Here he talks about a... -

bhobba replied to the thread Is the quantum wave function a real object or a mathematical tool?.Are the probabilities of the Black–Scholes model real? Thanks Bill

But that doesn't mean variables used in equations are real. Equations and their variables are mathematical tools we use to make...

bhobba replied to the thread Is the quantum wave function a real object or a mathematical tool?.It can't be real, only a very good approximation to something that many think of as real. That is because the current best theory we...

Love.
My opinion: I don't care. See, that's why @PeterDonis wrote: -

Physics is not about opinions. Different QM interpretations say different, and mutually inconsistent, things about what the wave...

Subatomic particles present wave-like behavior that is real and measurable but is not classical particle behavior. It's not just a...

bhobba reacted to renormalize's post in the thread Undergrad Why is a Gaussian function used to represent a wave packet? with Like.
Yes, the spreading of single-atom wave packets has been observed experimentally and agrees with theory: In-situ Imaging of a Single-Atom...

Do you have a reference for this? Please bear in mind that personal theories and personal research are out of bounds for discussion here...

How? Superposition means that equations are linear. You can do both QM and QFT in non-inertial frames, it's just tedious and gives...

You missed the point. I was not claiming that either Minkowski spacetime or Schwarzschild spacetime are realistic. They are just clear...

See the bolded addition in the quote above. Without it the statement is false. Again see the bolded addition. I think both additions...

No, I would make no such claim. The stretched rubber band has a nonzero stress and strain in it. This is physically measurable and...
