Here the American physicist Richard Feynman talks about how, although very young, he came to be involved in the WW2 atomic bomb project. He shares his thoughts on the moral dilemmas that faced him and his fellow scientists, including Robert Oppenheimer. This audio recording is largely outtakes from the filming for a BBC TV Horizon documentary called 'The Pleasure of Finding Things Out' (1981). The film negative and work print for this unused material were junked after transmission of the finished programme as was the practice at the time film cans took up a lot of space! But you can see the accompanying picture for the sections included in the final film at the BBC Archive website if you live in the UK, or on Vimeo worldwide search for 'The Pleasure of Finding Things Out'
