February – 2010 – Konrad Voelkel's Blog – Mathemagically

Sadly, Ubuntu is not perfect. A wish-list of future Ubuntu features/applications. Some are available on Windows or Mac OS X, most aren't.

In this post I present some of my favourites from the last months at MathOverflow.

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.

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.
