-
PeterDonis replied to the thread Undergrad If gravity is emergent, how does this affect string theory and loop quantum gravity?.That it's emergent from something else. No, that's not what "gravity" is when we're talking about whether it's emergent or not. What... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.But the two detectors are detecting different observables. Heuristically, the normal detector screen is detecting position, so it makes... -
PeterDonis reacted to gentzen's post in the thread Undergrad Particle vs Wave Interpretations of QM with
Like.
People working on the theoretical side of electron microscopy and charge particle optics know how to compute such scenarios. The... -
PeterDonis reacted to QuarkyMeson's post in the thread Graduate Time evolution of a detected particle with
Like.
The problem again is that this is not a normalized momentum probability distribution, its integral over p diverges. So you can't... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.If the tracks are sufficient to record which path information, why would there be any interference at all? -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.I hadn't thought about that explicitly, but if my claim that the tracks are sufficient to record which path information is correct, my... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.As I understand it, @Roberto Pavani intended a scenario basically as follows: (1) Start with a double slit experiment setup which is... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.Interference pattern of what? The plastic is not measuring impact positions. It's measuring tracks. What would an "interference pattern"... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.Mine doesn't. Let's suppose we apply a voltage of 1000 V to accelerate the protons; that gives them a speed of about 400,000 meters per... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.What's p? -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.I don't think your Mott track analogy works here, at least not the way you are trying to use it. In the case of the standard double... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.Is this a peer-reviewed paper? It doesn't look like one. Not to mention that the red lines are added by you. Is there a peer-reviewed... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.Please start a separate thread if you want to discuss a separate question. -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.How? In path integral terms, what contribution to the amplitude would such paths make? My answer is, zero, since the experiment is set... -
PeterDonis replied to the thread Graduate Time evolution of a detected particle.No, the particle's speed is extremely uncertain. It could be almost light speed or it could be zero. And it could be moving in any...
