The idea of the post is also based on something I'd been thinking about recently, in the process of revising my forthcoming book on quantum physics (due out in December)-- writing about quantum physics of everyday life forced me to deal with that a bunch. The fact that the rules of classical physics have quantum roots doesn't change the fact that they're very different from the underlying quantum rules. Of course, that doesn't mean there can't be quibbles and subtleties about what, exactly, counts as "weird" in quantum physics. There's one bit of quantum physics, though, that I think is inescapably weird, and that's quantum entanglement. If you pin down a bunch of people in the field, though, and ask them to name the single weirdest aspect of quantum physics, odds are they'll tell you it's quantum entanglement.
