Differential Geometry

Differential Geometry (UNSW). This is a collection of video lectures on Differential Geometry given by Professor N. J. Wildberger. The lectures present a systematic and sometimes novel development of classical differential geometry, going back to Euler, Monge, Dupin, Gauss and many others.

Differential geometry is the application of calculus and analytic geometry to the study of curves and surfaces, and has numerous applications to manufacturing, video game design, robotics, physics, mechanics and close connections with classical geometry, algebraic topology, the calculus of several variables and mostly notably Einstein's General Theory of Relativity.
