In 1975, R. Buckminster Fuller gave a series of lectures. In 42 hours he talked about everything he knows, as he called it "thinking out loud".
- You can watch a 40 minute part of the lecture at Google Video.
- The Buckminster Fuller Institute has a transcript of all 12 sessions.
- Greylodge.org links to video and audio files of the complete series but the source seems to be down at the moment.
