In this latest episode of the Physics World Weekly podcast, we discuss the science of sand dunes, and find out how dunes interact with each other as they move across the landscape. After that, we have a chat about our recent skiing trips and examine the physics underlying the formation and migration of moguls on the piste. We also take a look at snowmaking cannons, and whether the recent “warm” weather in ski resorts could preclude their use. Finally, we talk about a new variant of the classic Young’s double-slit experiments, which uses photoelectrons emitted via two different paths from rubidium atoms, and the implications of this research.
