The Schwarzian Derivative and 2D CFT - Projective Space, the Cross Ratio, Möbius transformations and SO(1,3), Conformal Transformations, three ways to understand the Schwarzian Derivative, Ridge Systems, the Virasoro Algebra, and why the Schwarzian appears in 2D CFT! (Lecture notes for graduate theory seminar)

The C Metric for Beginners (with pictures) - The C Metric is a spacetime describing two charged black holes which are uniformly accelerated by a cosmic string. The notes start with a review of the Schwarzschild black hole and its Euclidean section, then give an introduction to the Lorentzian and Euclidean C metric. It then describes how the Euclidean C metric is an instanton describing the decay of a cosmic string via quantum tunneling, and how the Lorentzian C metric describes a vacuum transition from one asymptotically locally flat vacuum to another by a superrotation.
