William Thurston, geometrizer of manifolds Sometimes I like to spend an hour looking at something I barely understand. The inside of this guy’s mind has got to be so interesting, but it’s been shaped by geometry rather than words, so … Continue reading

Manifolds, Star Fox, and SelfversusOther
Branes, Dbranes, Mtheory, Ktheory … news articles about theoretical physics often mention “manifolds”. Manifolds are also good tools for theoretical psychology and economics. Thinking about manifolds is guaranteed to make you sexy and interesting. Fortunately, these fancy surfaces are already … Continue reading

Pictures of the 3sphere, or should I say the 4ball? It’s a 4dimensional circle. Even though these drawings of it look completely sweet, I have a hard time parsing them logically. They’re stereographic projections of the hypersphere. All they’re trying … Continue reading
Complement
Here’s an insideout thought: The air around us is a 3manifold with 3holes where solid objects are, and the 2boundary is the ground. Or if you think of all the sky, it’s a spherical 3shell (with one 3hole, the Earth) floating … Continue reading

In the loop quantum gravity approach, spacetime is quantized by a procedure that encodes it in a discretized structure, consisting of spin networks and spin foams. A spin network consists of an oriented embedded graph in a 3dimensional manifold with … Continue reading
