One of my managers at work is, like me, fascinated with all things quantum, though for very different reasons. His interests seem to stem from the philosophical implications of quantum mechanics. While it may be fun to think about, I just don't buy all the quantum mystical mumbo-jumbo stuff. We've been having a friendly debate about aspects of QM but he seems to be stuck on a few things... Entanglement-He interprets it as everything being "connected", whatever that means. What I want to know is how do particles become entangled in the first place and it is something that occurs frequently in nature? And am I right in my thinking that not all particles are entangled? He's also latched onto the role of the observer, consciousness/thoughts creating or affecting reality, and superposition all rolled up into one. Can anyone provide info or websites? I really would get a good kick out of setting him straight!
