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

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

Spacetime is Curved
“General relativity can be summed up in two statements: Spacetime is a curved pseudoRiemannian manifold with a metric of signature . The relationship between matter and the curvature of spacetime is contained in the equation.” —Sean Carroll There you have … Continue reading
