I think administrators cowing to media pressure hurts the reputation of a university much more than piloting a long overdue and quite modest change to grading practices.

Imagine replacing people with tokens for plagiarism slot machines. This is why I take the extreme position that LLM-fuelled papers are not research, should not be read or cited, and should definitely count in one’s CV, but negatively.

THIS. AI isn't "going rogue" any more than those exploding Samsung galaxy phones from 2016 went rogue. Human engineers poorly deployed a technology and there were negative consequences. The responsibility falls entirely on humans.

For physics instructors, the takeaway is important: if our grading practices heavily penalize blank responses, exams may disadvantage some student groups and may not measure physics understanding equally well across students.

@djphysicswebb.bsky.social, Mary Chessey and I have a newly accepted paper on uncollected test item responses on open-ended physics exam questions! Blank responses on exams are missing data, not measurements of physics knowledge or skills. Read on for details... Preprint: arxiv.org/abs/2606.05473

Missing Data on Physics Exams: Demographic Patterns, Course-Level Predictions, and Implications for Equity
In a previous quantitative retrospective study we showed that different demographic groups of students leave different numbers of problems blank on physics exams, leading to inequities in course outco...

Abstract
We provide a clearer presentation of the Chair44 monotile, a new strongly aperiodic
monotile in three-dimensional Euclidean space E3
.
With LLM tools (ChatGPT Astra), Ioannis Tsiokos recently reported the first
known strongly aperiodic monotile in three-dimensional Euclidean space E
3
, the Chair44
monotile (see Figure 3, taken from Tsiokos’ preprint [11]). Hats off to Tsiokos for this
discovery, the framework he developed, and the human inquiry that led to the Chair44
monotile.
However, the paper itself and the formalization that it claims for support are not
in a form that is readily usable to anyone who wants to understand or check it. This is
not just because of the needless length or complexity of the argument (which is indeed
overwhelming as presented), or because the formal repository is not in normal form, or
because much of the text is misleading or poorly organized, but mainly because there
is so much irrelevant puff to push through. These are hallmarks of an LLM-driven
research paper.
We must, absolutely, insist on a higher standard for scientific discourse. The aim
must be to communicate, clearly, with people in the community — certainly this is an
historical requirement for publication.1

I know mathematicians aren't big on methods from other disciplines, but I feel like comparatists would have a field day examining this and e.g. the Leiden declaration

Starting to get kinda annoyed at senior mathematicians saying "I use AI to speed up my work because I have to. But we must protect junior researchers from being scooped. I just have no idea how!" You are the ones doing the scooping!

My take is that OpenAI, Anthropic et al. are in violation of the NC (non-commercial) variant licenses. I personally always opt for SA (share alike) licenses (a.k.a. copy left), which the AI companies also violate by not resharing their derivative works under the same license.

So not only was Navier-Stokes likely plagiarized, the Jacobian conjecture counterexample was likely plagiarized as well. arxiv.org/html/2609.05...
Supplemental AI statement of the third author. Very unfortunately and without me being aware, the in-progress version of this work dated January 14, 2025 was shared publicly at the link https://www.ihes.fr/~gabber/BGV160.pdf on January 16, 2025. My understanding is that after 18 months it became a feed of the AI models. On July 23, a graduate student sent me the 37 pages pdf file at the link https://people.math.binghamton.edu/adrian/AI.pdf produced by AI when prompted on how the 7 pages AI paper https://www.ulam.ai/research/jacobian.pdf relates to BGV160.pdf; a typo in the statement of Theorem 30.1(2.j) was fixed based on what the file mentioned (its application to Theorem 30.1(10.c) did not require any change).

Not impressed by colleagues who used blatantly unethical AI, helped it develop, got research funds from it, made advertisement for it, and now are clutching their pearls "oh no this isn't what maths is about" while carefully not apologizing nor promising to behave differently in the future.

I do not wade into discussions often, but I find the math community rallying around Alpöge, Buckmaster, and Coiculesco troubling. Like it or not by collaborating with Alpöge and using LLMs I think you are stepping outside of academic mathematics and into a PR war between Anthropic and openAI. (1/8)

I’m going to go out on a limb and say that if you are signing a letter supporting a disgraced eugenicist famous for hounding a Black scholar to death your main concern is not academic freedom. This goes double if you don’t have the same smoke for the Trump administration’s attacks on academia.

Why are otherwise smart people attributing human behaviors and thought processes to machine-learning outputs? Claude doesn't "identify a topic," it doesn't "write ," and "original" is doing a lot of work here. Machines do not think; humans do. AI has no episteme, it has probabilities & sequences

It seems many people are more interested in having a single, unequivocal answer than a correct answer, or being exposed to multiple alternative answers. This lack of a willingness to engage in critical thinking is quite worrying.

I'm sorry, the what problem?
Abstract
Consider a graph whose vertices are colored in one of two colors, say black or white. A white vertex is called integrated if it has at least as many black neighbors as white neighbors, and similarly for a black vertex. The coloring as a whole is integrated if every vertex is integrated. A classic exercise in graph theory, known as the Affirmative Action Problem, is to prove that every finite simple graph admits an integrated coloring. The solution can be neatly summarized with the
