Otsikko: [tuubi] Planeetat ja ellipsit! Kirjoitti: sideman - 08.11.2020 12:03:03 https://youtu.be/xdIjYBtnvZU This video recounts a lecture by Richard Feynman giving an elementary demonstration of why planets orbit in ellipses. See the excellent book by Judith and David Goodstein, "Feynman's lost lecture”, for the full story behind this lecture, and a deeper dive into its content. ...dsuu, dsuu, dsuu... ;) |
