In this brief yet expansive science lesson, the UK physicist and science educator Brian Cox explores how ‘each snowflake is a microcosm of the laws of physics’. Narrating over charming paper cut-out animation, Cox details a snowflake’s journey from its birth in the clouds to its final melting place, as well as how Johannes Kepler’s theory about their hexagonal shape would take some four centuries to be proved correct. Connecting the structure of these small ice crystals to that of spiral galaxies, this riveting dive into the natural laws that govern all things great and small will almost surely make you see the humble snowflake anew.
