Ppines-demon reacted to PeroK's post in the thread I Can this experiment break Lorentz symmetry? with
Like.
Researchers into quantum gravity are not going to change course because a student somewhere is mixing up classical physics and relativity! -
Ppines-demon reacted to sbrothy's post in the thread History Biographies, History, Philosophy of Physics with Like.
Triggered by this thread: RIP Rainer Weiss (1932-2025) arXiv: DEDICATED TO COSMOLOGY AND GRAVITATION - AS TOLD BY RAINER WEISS

Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.I was under the impression that it did not but I could not figure it out from the original paper. Wharton pre-print above says it is...

Ppines-demon reacted to PeterDonis's post in the thread I Violation of Bell Inequality with unentangled photons with
Informative.
It meets the standard definition of entanglement, correct? The joint state of the two particles can't be factorized into a product of... -
Ppines-demon reacted to martinbn's post in the thread I Violation of Bell Inequality with unentangled photons with Like.
What is indistiguishable here, the photons or something else?

Ppines-demon replied to the thread I Violation of Bell Inequality with unentangled photons.If this experiment holds it looks like a competitor to DrChinese's entanglement swapping arguments :oldbiggrin:

Ppines-demon reacted to chimay's post in the thread Solid State Ashcroft and Mermin: revised edition with Like.
Hi, I have notice that Ashcroft, Mermin and Wei worked at a revised edition of the original solid state physics book (here). The book...

Ppines-demon reacted to renormalize's post in the thread History Biographies, History, Philosophy of Physics with Like.
Paul Merriam's arXiv paper reads more like philosophy, with a capital P, not physics. All of its recent references appear in philosophy...

Ppines-demon reacted to PeterDonis's post in the thread I Modern View of Quantum Phenomena with Like.
That's not the assumption I'm questioning. The assumption I'm questioning is that "the relativity principle" is the same for Galilean...

Ppines-demon reacted to PeterDonis's post in the thread I Modern View of Quantum Phenomena with Like.
No, they don't. They're not a group in 3+1 spacetime; they're not closed under composition. Only in 1+1 spacetime do Lorentz boosts by...

Ppines-demon replied to the thread I Modern View of Quantum Phenomena.You seems to want to say that something can follow the first postulate of relativity independent if it is a relativistic or a...

Ppines-demon reacted to PeterDonis's post in the thread I Modern View of Quantum Phenomena with Like.
No, I'm not. I'm pointing out that "the relativity principle", as far as physics is concerned, is not one thing. Galilean invariance is...

Ppines-demon replied to the thread I Modern View of Quantum Phenomena.I guess I can try to understand what you mean here. But reading it for the first time, it looks like a complete fallacy. What you can...

Ppines-demon reacted to sbrothy's post in the thread History Biographies, History, Philosophy of Physics with Like.
Not much to report from here recently. I mean papers bluntly define themselves as metaphysics and iterate all the really hard problems...
