1975 Christchurch - New Zealand. Dirac's comments here can be nicely joined with the words of Heisenberg at http://www.youtube.com/watch?v=ZqfTO4NTqJ4 . Thanks to ThoughtThinksYou.,,this too is well worth listening to.
Branimir Vasilic has also kindly cleaned the sound and removed the 50 cycle hum. Big thanks - (I don't know how to do this!) See http://www.youtube.com/user/el3ktropionir/videos.
I'm very sorry the quality is so poor - these movies were made from old spool video tapes when the first video recorders had just become available in New Zealand. (The magnetic coating brushes off the tape when touched.) I only posted these because no other better stuff like this has yet been offered to the public. I found these lectures after years of thinking I'd stupidly lost them. I was recently cleaning out the garage and there they were! I had to share them immediately just in case I die tomorrow and no-one else in the world could offer anything like these little treasures. Although these recordings are substandard, I hope someone out there may enjoy them as much as I have. These movies suffer from age so for this, again, I offer my sincere apologies. Dirac deserves much better than this. I teach school but not at this level. Here they are then for you smarter guys out there. Dirac can never be forgotten....
