>I was referring to Heisenberg's uncertainty principle Now I see.. I only took a few physics courses and mostly associate his name when using the inequality, i.e what I think of when I read "uncertainty principle" (also, doing time-frequency signal processing/analysis). I was thrown off by the expression "quantum observation" because I thought you were talking about the observer effect, something that didn't really make me think of him. Maybe we can chalk it up to cultural differences, but we've never called it like that here (it was always "Heisenberg's uncertainty principle"). >the quotes in the link suggest to me that he has spent a large amount of time pondering ethics, unseen causality, and attributed intent. That is what I meant by seeking perspective. Indeed. I also think this is the case for the others, too. What's impressive was his almost forensic approach. His remarks read more like an autopsy than someone being in the situation he was in.
