Ppines-demon replied to the thread Predictions for the Nobel Prize in Physics 2025 (and results).Topological qubits do not exist yet, Microsoft released a fake topological qubit in 2025, but they are not sure if it is topological and...

Ppines-demon replied to the thread Predictions for the Nobel Prize in Physics 2025 (and results).I started the topic, because the first predictions are in. Domenico Fuoco from Polytechnique Montréal wrote a paper "How To Predict The...
-
Ppines-demon posted the thread Predictions for the Nobel Prize in Physics 2025 (and results) in General Discussion.Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a...

Ppines-demon reacted to Ibix's post in the thread I Can this experiment break Lorentz symmetry? with
Like.
But the results won't be exactly symmetric due to experimental error. So how big a deviation can you tolerate? To answer that question... -
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...
