Following Einstein: deriving Riemannian metric on the Poincaré disk
There is no geometry without metry. That is, without metric. It was Bernhard Riemann who gave the foundations to what we call today “Riemannian geometry”. When Einstein learned Rimennian geometry, he was able to compete with smart mathematicians and lay … Continue reading
