Quanti mechanics, in a sense, is the discovery that all quantits ar relation. You cannot avoid all the way down to the individual description o systems. If you try to associate non relation antitis to object, you get into contradictions. So objects have properties only relative to other objects and specifically whene they interact with other objects.
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.
