Absolutely wild to me that mathematicians can't be bothered to use their own brains to write a statement about AI use in math education. maa.org/wp-content/u...

This statement was developed with the assistance of AI tools used by contributors for various
purposes including drafting, note-taking, and summarizing, and was human-reviewed and
approved by the MAA Board prior to publication.

Went north, but not nearly as far, to see some trees this weekend

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).

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

This statement hasn't echoed enough fascist talking points yet, so they had to drop some xenophobia in there as well.

Universities should carefully evaluate and scrutinize formal and informal arrangements before accepting gifts or contracts from, or entering into collaborative relationships with, foreign entities or individuals.

I suppose one may have been able to make this argument in the past, but this laughable in 2026 as federal research funding is mired in political interference.

Federal investment in universities is grounded in merit guided by the national interest and policy priorities

It is well documented that standardized test are neither transparent nor objective, and are instead correlated with race and socioeconomic status.

Standardized tests or other transparent objective measures should be used wherever possible to ensure fairness and academic excellence.

If your institution's core purpose does not include supporting the humanity of all of your students, faculty, and staff, your institution is in fact engaged in this "politicization"

Institutional neutrality is a foundational component of a university’s commitment to its core purpose. To maintain public confidence and avoid politicization, universities — and their administrative leaders, including those in charge of academic units like schools, departments, and research centers — must refrain from taking institutional positions on political or social matters that are not directly connected to their core purpose.

Pretending that you do not have a politicsl ideology is in itself a political ideology

If faculty and students seek to pursue the truth wherever it lies, a university cannot have a political ideology or pursue a particular vision of social change

They have to be actively involved in the play, which they weren't here. See the IFAB guidance. www.theifab.com/laws/latest/...

While a forward (Team A) takes a shot on the goal, a midfielder (Team A) is standing in an offside position on the goal line. The midfielder does not attempt to play the ball and does not challenge the goalkeeper and other Team B players (no impact on the opponents). The ball goes directly into the goal. What is the correct decision?
The referee awards a goal because the midfielder has not committed an offside offence.

I generally don't share things from Substack no matter how great I think they are, but I appreciated this footnote on a blog post about alternative grading in large classes that addresses this. Too many folks just keep posting away without the slightest acknowledgement of what Substack stands for.

A note about the Substack platform from the authors. We had several conversations about whether we wanted to write a post that was published on Substack, given Substack’s current stance on publishing pro-Nazi and racist content. We decided to write this guest post because we think alternative grading can help move the needle in a more just and equitable direction, but we nevertheless want to collectively express our discomfort with Substack for choosing to promote and platform Nazi rhetoric. Notably, one contributor to this post chose not to list their name as an author out of a moral objection to Substack’s pro-Nazi stance.

Please tell me again about how grades are and have always been objective measures of students' learning.

I have tried to find ways to return to the old ethos of grading, in which I would judge a student as a whole person rather than as a series of assignment transactions. But in the age of courseware, I must give this holism a name and a value and a slot in the gradebook. Fine. I call it “Slush”—a grading category that I put into the system to account for whatever the rubric, the outcomes, and their computerized rigidity cannot. Slush is my gesture at an overall assessment of student performance and growth.
