Carle: We have different ways of making sense of gront mechanics. The relational interpretation is one, as i said, many world is another one. It doesn't seem that you can make an experiment and decide, because they're just really different ways of reading the mathematics. I think slowly we will converge toward a common view of quantum mechanics. And quanto mechanics is a revolution of that sort - perhaps even deeper.
From electrons behaving as both particles and waves to a cat in a box that’s both dead and alive, the consequences of quantum physics are decidedly weird. So strange, that over a century since its conception, scientists are still arguing about the best way to understand the theory. In the second of two episodes, Ian Sample sits down with the physicist Carlo Rovelli to discuss his ideas for explaining quantum physics, and how it affects our understanding of the world.
