Oh, that's a new one: Just received two different requests to review the same article (sent to two different e-mail addresses). I guess the journal using "AI to find and invite reviewers" might have something to do with this. #academicchatter #ai

Inspired by the recent AGI promotional piece in Nature, here's a suggestion for a test that LLMs will have huge difficulties with: Ask questions outside of its training data and ask for the confidence of the answer being correct. While LLMs might be correct […] [Original post on fediscience.org]

RE: https://mastodon.social/@europeanphysicalsociety/115966229883497497 The European Physical Society is now posting their materials also on here. Let’s give them a warm welcome and a reason to be even more active. ❤️ #physics

Together with Mario Birkholz of @neuSoM fame, I have written an article about Mastodon and the Fediverse in the journal of the German Physical Society: https://pro-physik.de/zeitschriften/download/23119 It's free to read but in German. Let's hope that @DPGPhysik's move to the Fediverse will […]

Topologically ordered states of matter are characterized by fascinating non-local quantum correlations in the many-body wave function. However, deciding whether a quantum state is topologically ordered or not is extremely difficult. A large part of the problem is that so far, signatures like the […]

So far, my Monday morning has consisted of writing to the editors of a journal that they published a paper containing a drove of AI slop references, helping my much-appreciated instance admin to reject a signup request from a vibe scientist, and dealing with a breach of confidentiality at a […]

Just been told that the German government plans to introduce legislation to change the Second Law of Thermodynamics, citing the need to dismantle regulatory barriers to the creation of highly efficient combustion engines. #physics #Germany #humor

RE: https://fosstodon.org/@AkaSci/115879641286036433 Well, as long as people are complaining about this on X or Substack, things will stay the same. Linus Torvalds didn't change the world by asking Microsoft for its source code.

My favorite Python program: a = 8 b = 0 while b != -1: if a % 2 == 0: b += 2 else: b -= 1 a += a//2 print("Hello, world!") Can you figure out what it is doing? It's less than 10 lines, so it surely can't be hard! Context: https://bbchallenge.org/antihydra #programming #computerscience

Large language models are pretty good for tasks that are hard to solve but easy to verify. A bit like NP-complete problems if you wish, although I wouldn't recommend to solve *actual* NP-complete problems using LLMs. Generating inputs for proof assistants, finding security bugs, and even […]

RE: https://machteburch.social/@tomkalei/115680143226592868 If you send AI slop to a journal, you should have to pay an article processing charge even though your manuscript gets rejected. #academicchatter

The highlights. ML can only be used where "its OK to be wrong", which usually means "its OK to be a little more wrong to be a LOT cheaper", which is the edge. Oh, and LLMs are very niche as they can't be used with "untrusted input + do bad thing". There is no market for the GW datacenters.

Given the drama surrounding the arXiv for its dependence on Google and its recent ban on review articles in computer science, I have a question: Do we still need the arXiv? Wouldn't a federated network of institutional repositories be a much better option? #arxiv #academicchatter #physics […]

The privacy implications of the new Verification of Payee scheme (mandatory since October for SEPA transfers) are ... interesting. I've been able to obtain the name of the second holder of a bank account without even knowing that there was a second person. #privacy #banking #sepa #eu #gdpr

Killer quote: “I’m going back to the Fediverse. Back to Mastodon. To the nerds, the hobbyists, the idealists. The people who don’t talk about reach, but about relevance. To those who understand that decentralization isn’t nostalgic, it’s the future. That digital sovereignty isn’t a gimmick […]

Large language models are quite useful to perform searches through the literature, so you have a good point to start. So, this is what I just got asking ChatGPT for references for the numerical calculation of the replica correlation lengths in topologically ordered systems: 1. Pizorn & […]

If you rely on a for-profit supplier, you should be required to carry the transaction costs to switch away from them as a form of debt in your books. Because the financing cost of this debt is what your supplier is eventually going to charge you. Allowing to hide this debt is creating some of […]

The option price betting that Nvidia's shares will crash below $40 (it's above $180 right now) by December 2027 went up by almost 50% last month, despite the underlying stock gaining over that time period. Looks like some people have started to run for the exit. #ai #nvidia #business #economy

TIL: apparently one of the main technical hurdles for universities to run their own #mastodon instances is to make the instance work with the institution's SSO (most often Shibboleth). It seems there would be a huge opportunity to facilitate the entrance of such major multiplicators into the […]

@dangillmor As Cory Doctorow repeatedly points out, apps are just websites wrapped in DRM. What about if we just start building websites again? It could be the future.

Large language models are essentially solutions to nonlinear optimization problems to predict the next token in the output text. Mathematically, these problems are quite similar to problems we routinely face in physics, like finding the ground state of a quantum system. In these physics […]

It is good IT Security practice to separate data from code. For example, an SQL Injection attack is to get the target to treat data (entered into a form) as code, that is break that barrier. Now take an "AI agent" doing a task for you like: "Download that podcast that Frank emailed me about" […]

Corporate fraudsters love AI because LLMs will fake it if necessary. For a while, company figures will look fine, and when the house of cards collapses, nobody will have to go to jail. Just imagine how easy you can build something like Dieselgate with vibe […] [Original post on fediscience.org]

Sorry @brembs, but Open Research Europe is a recipe for disaster. It's centered around the idea of big publishing, i,e., there is one huge contract awarded to a big player who runs the entire platform. Currently, it's Taylor & Francis, but if that changes to one of the other big ones, it will […]

Q: What is the largest number that has been factorized using Shor's algorithm on a quantum computer? A: No number has ever been factorized using Shor's algorithm on a quantum computer. Even for factorizing 15, the smallest possible number, the modular exponentiation part of Shor's algorithm […]

The Ising model in a transverse field is one of the most fundamental models in quantum many-body physics. Despite being around for more than 60 years, we still make new discoveries in it. In our latest work, we show the existence of a dynamical phase […] [Original post on fediscience.org]

Abrikosov vortices (fluxons) are quantum of magnetic flux (Φ~hc/e) which appear in type-II superconductors (SC) induced by persistent current loops. Fluxons allow magnetic fields to penetrate a type-II SC causing magnetic pinning. 🧪⚛️ #Science #Physics #QuantumMechanics See: doi.org/10.1038/srep...
