If you were to throw a baseball, physicists could tell you what its trajectory would be. The same goes for an electron in classical mechanics. But what happens when we move onto the quantum scale? Suddenly, predicting the path of particles becomes much more complex. Euan McLean explains how physicists are creating spacetime simulations to solve this problem.

The 2000 cult film ‘Dude, where’s my car?’ portrays two young men, Jesse (Ashton Kutcher) and Chester (Seann William Scott), on a journey to find a car. In this episode, UCL philosopher Luke Fenton-Glynn suggests they could have turned to philosophy to find it, and that policy-makers could do the same to tackle hard practical problems such as climate change.
