Writing about the paradoxical nature of quantum mechanics poses a peculiar paradox of its own. If you explain it well enough that your readers understand it, you've somehow committed a gross error, because (as Feynman famously said) nobody really understands quantum mechanics.
But don’t worry. There is no danger that anybody reading this blog will come away understanding it. Nevertheless there are some new developments in the never-ending quest to explain quantum physics that, even if hard to understand, are worth knowing about. Especially considering where these new developments come from. Two giants of 20th century physics have recently offered 21st century views on how to interpret the quantum math that requires the subatomic world to be so weird.
The giants are Steven Weinberg (Nobel 1979) and Gerard ’t Hooft (Nobel 1999). They both played key roles in forging the modern understanding of particles and forces known as the standard model. They share a deep concern about the issues afflicting efforts to understand the foundations of quantum mechanics. But they offer very different views on what to do about it.
