Physicist Steve Hsu just posted a new arXiv paper showing how GPT‑5 can assist in physics research, from hypothesis generation to quantum‑foundations checks, while stressing human oversight. Could this be the next leap for large language models in science? Read the full analysis now. #GPT5 #SteveHsu #GenerativeAI #QuantumFoundations

This week was good for #QuantumFoundations in the Arxiv; this one is particularly interesting because the usage of operational theories is not only a foundations matter, but it is highly used in applications and proofs of quantum information advantage.
It is a constant aspect: quantum foundations keep proving itself interesting for the applied physicist. In defense of quantum foundations, here is an g(old) gem!

Just finished reading an interesting paper discussing non-linear dynamics.
The claim can be explained with the following task: Consider a researched in its laboratory (system S) and a physical system being tested (system A). Can the researched discriminate/learn if the total system SA is coherent, performing only local tests inside the laboratory?
The work shows that this is possible iff the theory allows for non-linear dynamics. (1/n)

Interesting unpacking from Hossenfelder on the issues she has with particle physics.
But I'm not sure she herself is immune from the motivational issues she cites. For example, are her reasons for preferring hidden variable theories in QM really any different from the ones she's criticizing here?
To be fair, I doubt anyone really avoids these issues. Testing matters! And which tests to fund seems inevitably a judgment call.

Q16 (part B): What is your reason for NOT favoring De Broglie - Bohm theory?
A: It is too complex compared to other interpretations - i.e. Ockham's razor
B: It has hidden variables, which makes the theory untenable according to Bells inequality
C: Nonlocality
D:The notion of all particles possessing a quantum potential that guides them seems too farfetched
E: Other

Ethan Siegel here argues we shouldn't explore quantum interpretations, because they can't currently be adjudicated empirically.
It's worth noting that Einstein and colleagues received this type of criticism with their 1935 EPR paper. If everyone had heeded it, this year's Nobel prizes for entanglement experiments wouldn't exist.
Curiosity, and attempted explanations, are a good thing, as long as we remember the status of those explanations.

@ZachWeinersmith I feel like superdeterinism should be called something like "Universal Conspiracy", because it amounts to the universe, from the big bang forward, being arranged in just such a way to make sure our little experiments have correlations they shouldn't.
