We also have fantastic sessions on Anosov representations, Group actions on hyperbolic spaces, Knots and links in dimensions 3 and 4, Number theory in low-dimensional topology, Teaching undergraduate topology, and Teichmuller space and geodesic currents! ncngt.org/2022-topic-gro…

I loved learning from @RanthonyEdmonds, Arunima Ray, Rebecca Black, Anthony Bosman, and Christian Millichap today. I have so much to think about for the future. Surprising to me/ maybe my favorite part--how much I took away for non-topology courses! ncngt.org/2022-topic-gro…

NCNGT 2022 participant interests as word cloud--most of the big words aren't too surprising, but some of the small ones make me smile!

I have a linear algebra student who is interested in doing a mini-project on "something related to matrices and binary." Ideas for references? Ideally it would be an intro to linear algebra over a field of order two, with applications, but any recs would be v welcome!

Two questions: 1. Do you have a favorite book for a first course in undergrad algebra, and if so what is it and why? 2. To you, are group actions or group homomorphisms more fundamental things to think about?

Darth Jamie and I wish you all a very happy Halloween.

I have a memory of a great "what is a proof" class activity/ exploration posted within the last year (I know, very helpful.) Does this ring a bell for anyone?

I appreciate Ed Yong's writing on COVID so much, especially his insistence on paying attention to peoples' experiences as the "ground truth against which all other data must be understood." theatlantic.com/health/archive…

NCNGT 2023: 5 fantastic topic groups ncngt.org/topic-groups-2… 3 terrific plenary speakers ncngt.org/live-events-an… 1 more day left to apply to participate! docs.google.com/forms/d/e/1FAI…

Gradescope, I love you dearly (particularly the ability to never again worry about losing students' homework), but is allowing EVERY EMOJI to be given as student feedback really a wise choice?
