Hi there! I'm a theoretical physicistI work on topics related to general relativity. I currently teach classes at St. Edward's University and work as an affiliate researcher at the University of Texas at Austin. Here's my cv. PhysicsNotes:The Poor Man's Introduction to
Tensors  These are my notes on tensorsthey serve as an introduction to tensor calculus (in Euclidean space) accessible to those with a basic knowledge of linear algebra and vector calculus.
