The Vega Science Trust - Richard Feynman - Science Videos

A set of four priceless archival science video recordings from the University of Auckland (New Zealand) of the outstanding Nobel prize-winning physicist Richard Feynman - arguably the greatest science lecturer ever. Although the recording is of modest technical quality the exceptional personal style and unique delivery shine through. Feynman gives us not just a lesson in basic physics but also a deep insight into the scientific mind of a 20th century genius analyzing the approach of the 17th century genius Newton. For the young scientist, brought up in this age of hi-tech PC/Power Point-based presentations, we also get an object lesson in how to give a lecture with nothing other than a piece of chalk and a blackboard.
