WHYB maths
Welcome to WHYBmaths! My goal is to try and bridge the gap between physics and rigorous mathematics. I will mostly be focusing on Tensors and Manifolds, as I have often found the presentation of these subjects (for a physics audience at least) to be lacking in mathematical detail. I am currently working on finishing the differential geometry series with Lie groups and Principal bundles and also working on a full series covering special and general relativity using all the differential geometry previously covered!
Check out my GitHub repository that has notes and other interesting stuff!
