Is It Even Possible to Understand Quantum Mechanics?
A big problem with physics is that it’s invented by humans. We see stuff around us and use our observations to build a mental model of the world. Children do this, and of course physicists keep right on doing it. In many cases, this is awesome. It's how we got Newton's laws of motion. But it goes sideways when we try to picture the behavior of tiny, invisible things like subatomic particles.
This is the “quantum realm,” as they call it in Ant-Man. It's not really a place you can visit in a special suit; you're already in it, and it's in you. But quantum phenomena are so alien that this deep layer of reality may as well be an alternate universe. The physicist Richard Feynman once famously said, “Nobody really understands quantum mechanics.”
Feynman didn't mean we can't explain quantum behavior. Today we have models that...
