Paul Colby replied to the thread Graduate Best visualization of SO(3).Visualize as a manifold seems to be all you consider. There’s the algebraic aspect of ##SO(3)## as well. -
Paul Colby replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.Given your original question concerning photons and the double slit experiment, how have your views changed? The experiment showed that...

Paul Colby reacted to Hornbein's post in the thread Backyard Trebuchet Breaks Sound Barrier with
Like.
Carbon fiber, 3D printed parts, multiple rotations. Numerous small refinements of the design to get to a 776 mph release. Your castle... -
Paul Colby reacted to PeterDonis's post in the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same? with Like.
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...

Paul Colby reacted to BvU's post in the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same? with Like.
Have you seen the video "How big is a photon" mentioned in a similar thread here ? ... :smile:

Paul Colby replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.Interference patterns happen for multiple “it”s, right? From post #5 “it” was water waves, sound waves or EM waves. “It” could also be...

Paul Colby replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.What is “it” in terms of currently accepted theory?
-
Paul Colby replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.Except, this sounds to me like you're infering one event, photon emition, from the photon detection. That's not how thermal sources...

Paul Colby reacted to renormalize's post in the thread Undergrad How does a cloud chamber respond to 2-slit interference? with Like.
The Motivation Spurred by some interesting back and forth with @PeterDonis in a recent forum thread, I present here my attempt to answer...

Paul Colby reacted to weirdoguy's post in the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same? with Like.
For massless fields with spin 1 or more, we can't construct position operator, so one can't think about photons traveling along any path...

Paul Colby replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.More specific? I was discussing just the quoted statement I quoted in post #15. Hard to get more specific. What is really called for is...
-
Paul Colby replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.Actually, I would say your statement is filled with notions that are incorrect. A double slit interference pattern happens independent...
-
Paul Colby replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.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...
-
Paul Colby replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.A double slit interference pattern can be produced using sound or water waves. So interference is a wave phenomena in each of these...

Paul Colby replied to the thread Undergrad Mass-and-spring model of parametric amplification.The issue I have with this is the equation of motion, ##m\frac{d^2x}{dt^2} + k(t)^2x = 0##, Is quite different than this one...
