| Mar 22, 2012 at 16:57 | comment | added | roy smith | Gauss apparently defined curvature, as repeated by Riemann in his paper translated in Spivak, as (the angle sum minus 2π)/area for an infinitesimal triangle centered at the point. This occurs in a nice article about Descartes' anticipation of Euler's theorem: ams.org/samplings/feature-column/fcarc-descartes6 Another nice elementary discussion is in chapter 7 of Experiencing Geometry, 2nd edition, by David Henderson. see also: post #29, my paragraph on parallel transport: physicsforums.com/showthread.php?t=578235&page=2 | |
