1. LETTERS TO THE EDITOR| September 01 2024 It is time to honor Emmy Noether with a momentum unit Geoff Nunes, Jr. Am. J. Phys. 92, 647 (2024) https://doi.org/10.1119/5.0229624 I have been teaching physics, on and off, for 30 years now, and every time I get to momentum and start writing “kg m/s” for the unit, my students ask if there is some official unit they can use instead. And every time, I have to inform them that, sadly, there is not. The International System of Units contains seven base units and 22 derived units. Of these units, 17 are named in honor of people, every one of whom is a man. It seems to me that momentum offers the perfect opportunity to admit a woman to that club. For several years, I have been declaring that, in my class, one kg m/s is equal to one Noether, in honor of Emmy Noether, whose theorem shows, among other things, that space translation symmetry results in conservation of momentum. Formal adoption of this new unit by the Bureau International des Poids et Mesures may take a while. I propose that we teachers start the process from the grassroots. Let us adopt the Noether in our own classrooms and abbreviate it Nr (which is shorter—what my students want—and which will honor Emmy Noether's contributions to physics—what is long overdue).

@ColinTheMathmo Cute. I get 44.05 (giving you an extra digit since it was a five).

@ColinTheMathmo Or 44.0 if we're using the more numerically stable round-to-even 🙃
I could see using this when tutoring a student one-on-one in trig, to help cement the concepts. I agree with the other commenter that asking for the exact angle at A would be a good thing.

@nova I've been assuming it's the MCP from Tron.

Culture is kept in our conversations, for some loose definition of 'conversation'.I work in software and currently lead a team of physicists, MEs, EEs, and software engineers, all working to protect the biosphere.I have a background in physics and math to the BSc level. My posts tend to be a mélange of all the above, and a bit more.
