Everyone has heard of quantum physics. Many of us can parrot its key ideas – uncertainty, entanglement, collapsing the wave function, something to do with a cat…

But when it comes to really understanding it, well that’s a different matter altogether. “Anyone who is not shocked by quantum mechanics hasn’t understood it”, wrote the eminent physicist Niels Bohr.

So, what is quantum physics? How did it come about? What does it say about ultimate reality? And how might it transform our lives?

This week on Reading Our Times, Nick Spencer delves into the quantum realm with scientist Paul Davies to discuss his latest book, Quantum 2.0: The Past, Present, and Future of Quantum Physics.
