Professor Walter Lewin's video lectures

No bullshit ! just the integrality of M.I.T. video lecture from Professor Walter Lewin...

After the Massachusetts Institute of Technology  decided to remove all the video lectures of Professor Walter Lewin from the "MIT OpenCourseWare " (https://ocw.mit.edu/courses/audio-video-courses/) , I decided to upload them here to help studiants in their work.
