i'm not trying to revolutionize the teaching of quantum mechanics, but i do want to nudge it in a productive direction. Entanglement will be there, non optional. But then you can choose to still spend a lot of time doing clepch gordon coefficions and editions of spins if that's what gets your juices flowing. We'll see if it all pans out. Gregory kusnick says since events at the scale of human affairs are effectively classical and deterministic, we should expect histories that diverge radically from our own. I don't see how this follows. It seems to me there's ample scope for quantum uncertainties in things like genetic recombination and the r
