PeterDonis's latest activity
-
PeterDonis replied to the thread B Need help understanding particle physics and quantum physics.None. The electron is a fundamental particle in our best current theoretical models. (But "particle" is just shorthand for "quantum... -
PeterDonis reacted to Nugatory's post in the thread B New idea about wave-particle duality - looking for feedback/criticism with
Like.
You have been victimized by pop-sci misdescriptions. The entire notion of “wave-particle duality” was abandoned as a false start almost... -
PeterDonis reacted to Ibix's post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with Like.
I also agree. To call what you get with a homogenous but anisotropic two way speed a "simultaneity plane" you need to require that...

PeterDonis replied to the thread B Trying to calculate proper time of worldlines using rotating frames.The velocity limit won't be, but you won't be able to integrate over p2's worldline past a certain point, because, as has been pointed...

You might want to, as it makes it possible to prove that a message came from you. Say you want to make a public proclamation that is...

PeterDonis replied to the thread Is this public key encryption?.Try this: I send you a box and a padlock that's currently open. I have the key to the padlock, but no one else does. You put your...

PeterDonis replied to the thread B Trying to calculate proper time of worldlines using rotating frames.That is Born coordinates. I don't know what you mean by this. A number ##\omega## appears in your metric; that appears to be a fixed...

PeterDonis replied to the thread B Trying to calculate proper time of worldlines using rotating frames.Then I'm confused. The metric you gave in post #7 is for Born coordinates.

PeterDonis reacted to .Scott's post in the thread Who is responsible for the software when AI takes over programming? with Like.
The same people who were responsible before the AI "took over". If someone does their home work with AI assistance, it is still their...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.For a critique of her treatment of Feynman from someone who was in a much better position than she to know relevant facts, see this...

PeterDonis reacted to JimWhoKnew's post in the thread B Trying to calculate proper time of worldlines using rotating frames with Like.
As @PeterDonis said in #22, the OP calculated in the Born coordinates (see the "edit" note at the end of #20). I just "tidied up" the...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.Oh, for goodness' sake. I'm sorry to sound blunt here, but if you feel cheated because you didn't think to look at the inside cover of...

PeterDonis replied to the thread I Schrödinger equation and classical wave equation.I'm not sure what you're asking for in post #8. That might help here, yes. The Schrodinger Equation is (writing it in one spatial...

PeterDonis replied to the thread B Trying to calculate proper time of worldlines using rotating frames.I'm not sure the OP is actually using the same Born coordinates for both observers. The calculation in post #7 looks like it's...

PeterDonis reacted to Dale's post in the thread I Is Maxwell's electromagnetism an effective (field) theory? with Like.
Unfortunately, that means the topic is not suitable for this forum. We exclusively focus on topics that are in the literature. We could...
