Diagonals of an ellipse

I have been watching Norman Wildberger’s videos on all things mathematics for about 10 years. To say that I have learned a lot is the understatement of the decade. His most recent video is a recorded talk from July this year titled “How Chromogeometry transcends Klein’s Erlangen Program for Planar Geometries”. It is fascinating throughoutContinue reading “Diagonals of an ellipse”

I am not a mathematician. During my training as a physicist I developed some competence in fields like geometry, algebra, and calculus, but I do not have the ability to create mathematics. I even find it really hard to read the mathematical literature. So I am probably missing out on exciting methods that may beContinue reading “Watching geometry on YouTube”
