 But this fundamental idea that things travel as waves wasn't too controversial, but the fundamental idea that they did both travel as waves and then jump when you look at them was very upsetting to a large number of physicists, including those that were instrumental in developing the theory of quantum mechanics. Here are some of the things they said. So despite all these misgivings, quantum mechanics kept on giving us such accurate and precise answers to questions about how the universe around us works. It gives us theoretical calculations that agree with experiment up to 14 significant figures, better than any other theory we have. And the fact that it's so successful means that perhaps all of this problem with the worldview is more about our intuition and our own prejudices rather than about the world around us. After all, we don't get to tell the universe how it's supposed to work, just because that's how we expect, the universe gets to tell us how it works and we have to adjust our intuition to suit. A couple of generations later, Richard Feynman said this. A couple of generations later, and physicists really are more comfortable with quantum mechanics. We've gone from the point of questioning its every axiom and trying to reform it into a more pleasing theory, and we're focusing more these days on actually doing engineering with it. We're deliberately using its strangest behaviors to build novel technologies like quantum computers.
