That's where I found out what makes that screeching noise when someone takes over a microphone... audio (positive) feedback that amplifies the resonant frequency (circa 15kHz to 18kHz) to saturation!This book contains a lot of nifty paradoxes. I must say that Prof. Doug Hofstadter sounds like Prof. Marvin Minsky at times, regarding the study of how brains think, consciousness, AI, semantics, etc.
