It's fascinating to me that giving someone a "beat down" is the same thing as "beating them up". It implies that beating exists in some sort of non Euclidean space that folds in on itself.
This past October, dozens of mathematicians gathered in Pasadena to create the third version of “Kirby’s list” — a compendium of the most important unsolved problems in topology, the study of deformable shapes.
++ Video is visually appealing, compact (28'). Tries to present the question of finiteness || infiniteness of Universe within the context of relativistic #cosmology. Intros to 2D #topology + #curvature are fair. Publicity for my group's research is nice :).
The relation to 3D topo+curv is absent; there are several bloopers in the narration.
I remember one time I ...found a book w/ pdf.
It was about displaying dynamical systems theory, showing manifolds and so on.
Plots were not made with any programming language, they were actual drawings, pastels, watercolors.
It's the type of book I literally have dreams about, but I think this one exists😅 what was it?
Our redesign for https://topology.pi-base.org finally launched! If you might be teaching #topology someday, I'd love to chat about ways to use it in your #classroom. And we're always looking for students and faculty who want to contribute to its content...
For #ArtAdventCalendar Day 13: Happy birthday to #mathematician Virginia Ragsdale (1870-1945). The Ragsdale conjecture, made in her 1906 dissertation, is amongst the earliest and most famous on the #topology of real & algebraic curves, which stimulated a lot of 20th century research & was not disproved until ‘79. A correct upper bound has yet to be found. In her dissertation she tackles the 16th of David Hilbert’s famous 23 unsolved 🧵1/n
