Episode notes

In your book, you say that the philosophers got here first. What does it mean to exist by itself is a very hard notion to pin point? We may think that it exists, but it has no act whatsoever. If we base physics on this idea, namely, that to exist is to interact, then suddenly i think quanto mechanics make sense. The key point is not to assume that there are non relational properties.

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.
