Richard Feynman once famously said that if you think you understand quantum physics, you don’t understand quantum physics. And while this quote is still popular today, Feynman died nearly forty years ago, and physics has since moved on.
So, is it possible to understand quantum physics? And if so, to what degree? Where are we in our current understanding?
Joining my today is Jim Al-Khalili, an Iraqi-British theoretical physicist. He is professor of theoretical physics and chair in the public engagement in science at the University of Surrey, and a recognisable figure in popular science.
