Found on MathOverflow
In this post I present some of my favourites from the last months at MathOverflow.
Subject: mathematics
Walk-through to Morel-Voevodsky A¹-homotopy theory, page 48-50
Chapter 2.1. Homotopy theory of simplicial sheaves: The simplicial model category structure. Discussion of 1.2, 1.3, 1.4, 1.5, 1.6, 1.8, 1.9, 1.10.
Beautiful new geometry videos
On dimensions-math.org you can see a whole bunch of before unseen geometry videos introducing 2-, 3- and 4-dimensional space, complex numbers and even more to the non-mathematician.
Video: Some important themes in geometry
Mathematics for non-mathematicians: I recommend a talk by Dan Freed, “The Hodge Conjecture”. You’ll get a glimpse on some central ideas of geometry from this talk, even if you’re not interested in the Hodge Conjecture.
