MIT 8.962 General Relativity, Spring 2020 • Instructor: Scott Hughes • View the complete course: https://ocw.mit.edu/8-962S20 • YouTube Playlist: • MIT 8.962 General Relativity, Spring ... • The kinematics of bodies in spacetime. Free fall described by geodesics: trajectories that parallel transport their tangents through spacetime, and extremize the experienced proper time. How symmetries of spacetime lead to quantities being conserved along geodesics; associated notions of 'energy' and 'angular momentum' for certain spacetimes. • License: Creative Commons BY-NC-SA • More information at https://ocw.mit.edu/terms • More courses at https://ocw.mit.edu • Support OCW at http://ow.ly/a1If50zVRlQ • We encourage constructive comments and discussion on OCW’s YouTube and other social media channels.
