PeterDonis replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.So far, it doesn't appear that anyone in this thread but you understands whatever issue you think you're asking about. If you can't... -
PeterDonis replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.Except when it doesn't, as I pointed out in my post #22, which you did not quote.

PeterDonis replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.There is no observation that tells you that light traveling in free space is made of photons. So I don't know what you're referring to...
-
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.No, an excitation in a quantum field has energy. Sure, energy and mass are equivalent. That doesn't mean a quantum field excitation...
-
PeterDonis replied to the thread Undergrad Comparing the time of two moving clocks.No, this is not correct as a description of what each observer actually sees--the timing of the light signals they receive. If the two...

PeterDonis reacted to Matterwave's post in the thread Undergrad Particle vs Wave Interpretations of QM with
Like.
What do you mean by "highest level"? QFT and GR both form our fundamental understanding of physics. Creation operators are a... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.A creation operator does not represent an actual physical process. (It's not even an observable since it has no eigenstates.) It's a...

PeterDonis replied to the thread Graduate Position vs momentum measurement.I'm not sure he meant spacetime positions, just spatial positions--i.e., I think he's implicitly assuming non-relativistic QM.
-
PeterDonis replied to the thread Undergrad Comparing the time of two moving clocks.I don't think this is true. You're asking the same question here that you asked in your previous threads (of which there have been more...

PeterDonis replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.Perhaps you would say that, but that's not what the math says. The math says that the interference terms in the relevant wave function...

PeterDonis reacted to Paul Colby's post in the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same? with Like.
My training is in experiment side of physics. If I turn on this "forced physical" interaction, I would have to get up from my stool and...

PeterDonis replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.@aletheia I have deleted some comments in two of your posts complaining about what you're not allowed to post here. Any further such...

PeterDonis reacted to robphy's post in the thread Undergrad How does reciprocal time dilation work? with Like.
Just a postscript... (thanks to a mentor for re-opening this to allow me to make this hopefully-helpful comment) Since the OP recently...

PeterDonis replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.Moderator's note: Two posts discussing a paper on "dark photons" have been deleted. It's not clear that that paper is even a valid...
