scifimath Posted August 26, 2019 Posted August 26, 2019 First, are you claiming they are both at the same time or not? What started this assumption? In what world is an electron equivalent to a whole atom? So, I'll take this to mean we haven't tested two unobserved atom matter waves interacting? Oh, we have, but it does the typical thing of a fringe pattern. They don't ever bounce off each other like they were physical at the time. hmmm I'll bite, what does your electron experiment look like? Does it somehow display the electron and wave version at the same time while it propagates on its path? Why would orbitals have anything to do with what I'm asking for? I'm not interested in atoms exchanging electrons. You are assuming they are both at the same time because you are not taking observation into account. You wouldn't catch a quantum wave being a wave before it went through a detector (that it was moving towards). The particle is likely pre-set to be physical or a wave before it starts moving. This is what the experiments are showing us, no?
studiot Posted August 26, 2019 Posted August 26, 2019 Quote Help me understand your POV of Duality Duality has many guises and forms over a very wide range of situations. It is instructive to study some simple types of duality to gain understanding of the phenomenon. This picture, for instance, offers a simple type of duality applicable to the property of shape. 1

scifimath Posted August 26, 2019 Author Posted August 26, 2019 Previous threads that were shut down prematurely. yes, the illustration is clever, but I don't think it applies. I'm fine with duality ..just not at the same time.

scifimath Posted August 26, 2019 Author Posted August 26, 2019 then why did swansont say this Quote This makes no sense. Wave-particle duality does not say that wave and particle behavior will be observed at the same time. If you tell me it’s a matter wave, I can’t show you particle behavior. But in interference, you get the wave behavior, and later on, when you detect, you get particle behavior.
Strange Posted August 26, 2019 Posted August 26, 2019 7 minutes ago, scifimath said: then why did swansont say this Because <sigh> as with the picture above, you can either see a candlestick OR faces, not both. Similarly, you can either measure wave-like properties or particle-like properties, not both. Maybe it's just me, but perhaps it might be a good idea to learn a little basic physics before going off and making up your own "theories". I know it is so much easier to make stuff up from a position of ignorance, because you don't have to worry about all the complicated details and the mathematics, but it is a rather futile pursuit. The only person who will be impressed by the power of your imagination is yourself. 43 minutes ago, scifimath said: Oh, we have, but it does the typical thing of a fringe pattern. They don't ever bounce off each other like they were physical at the time. Waves cause interference patterns but don't bounce off one another.
scifimath Posted August 26, 2019 Author Posted August 26, 2019 You aren't taking observation seriously, because if you did, you would know duality (at the same time) is nonsense.

This was all about observation: "Similarly, you can either measure wave-like properties or particle-like properties, not both." Observation is an important part of quantum theory. It is taken into account all the time.

scifimath Posted August 26, 2019 Author Posted August 26, 2019 Observation gives one type of result ..a physical one. (unless you messing around with polarizers) Yes a parlor trick was going to pull me over to your side.

scifimath Posted August 26, 2019 Author Posted August 26, 2019 when does observation show wave-like properties? The final screen of an experiment doesn't count as observation
Strange Posted August 26, 2019 Posted August 26, 2019 Just now, scifimath said: when does observation show wave-like properties? When you observe wave-like properties. Obvs. Measuring wavelength, is one obvious example. Interference is another (even though it seems to annoy you for some reason).
scifimath Posted August 26, 2019 Author Posted August 26, 2019 You can physically measure the wavelength of a matter wave? Interference is the final screen. Observation is only involved while the particle is in flight.

Obviously. 17 minutes ago, scifimath said: Observation is only involved while the particle is in flight. Obviously not as we observe where the photons/electrons/atoms etc “hit” to determine the interference pattern. So that observation happens when the particle is not in flight.
scifimath Posted August 26, 2019 Author Posted August 26, 2019 What instrument measures the wavelength of a matter wave? And don't say a calculator. The final screen doesn't count as observation because if it did ..the particle would not ever show fringe.
swansont Posted August 27, 2019 Posted August 27, 2019 37 minutes ago, scifimath said: What instrument measures the wavelength of a matter wave? And don't say a calculator. The details of an interference pattern gives you the wavelength. e.g. the separation of the fringes. We use the same/similar method with light. Quote The final screen doesn't count as observation because if it did ..the particle would not ever show fringe. Bollocks. The final screen shows the position of the particles. The interference happened at the slits. There’s no conflict. 1

scifimath Posted August 27, 2019 Author Posted August 27, 2019 So I guess I found the spot you guys don't want to let go of. It most certainly is not bollocks when it comes to what is counted as observation. Observation has to let the particle to continue moving or else it's void.

You aren’t exactly in a position to say, seeing as how you clearly don’t understand the physics.
scifimath Posted August 27, 2019 Author Posted August 27, 2019 Someone was trying to claim the matter wave of an election should hold the results as an atom. Fringe is not evidence of physical objects interacting. knaww, I think I got you guys on this one. You are kidding yourself if you see the final screen as observation ..the particle didn't.

uncool Posted August 27, 2019 Posted August 27, 2019 I already have. To spell it out more clearly: You are attempting to impose an idiosyncratic definition of "observation" that does not match how it is used by physicists, and then spinning the refusal to accept your idiosyncratic definition as if it means they must be hiding something.
