Lost In Space-Time
This evening I've been caught up in the early-week ritual of watching re-runs of the late-seventies series "The Secret Army" [Google it if you're too young to remember it], which is, for someone of my generation, a bit of a guaranteed time-waster, as it is so compulsive. Whatever. Before settling down to watch the umpteen episodes in tonight's linear binge-feed, I was re-watching an interview on YouTube with Professor Sir Roger Penrose, regarding [particularly] his thoughts on the rôle of the 'observer' in the collapse the of the wave function in quantum mechanics. As you do. He, I think quite reasonably, argues that the notion of a simple observation of a quantum superposition of states by a 'consciousness' leads to that collapse is actually pretty daft. But the counter thought experiment that he uses is also basically flawed in my book: he uses the photographic medium as the intermediary recorded state of the quantum superposition, positing that ...
