Even after a century of working with quantum theory, we still don't understand it particularly clearly. We have multiple different explanations as to to what's going on. It has given us predictions like entanglement, which was first predicted and then observed. All sorts of things were predicted theoretically and then realized concretely. And yet, if we try to ask ocaso, what is it telling us about the world? Don't ask. That's it for part one. On thursday, we'll be leaving the shores of helgo land and heading into deeper waters to investigate the relational interpretation of quonto mechanics. Join us again on th Thursday for that. This is the guardian.
It has been more than a century since the groundwork of quantum physics was first formulated and yet the consequences of the theory still elude both scientists and philosophers. Why does light sometimes behave as a wave, and other times as a particle? Why does the outcome of an experiment apparently depend on whether the particles are being observed or not? In the first of two episodes, Ian Sample sits down with the physicist Carlo Rovelli to discuss the strange consequences of quantum theory and the explanation he sets out in his book Helgoland.
