Forces of Nature
Professor Brian Cox combines some of the most spectacular sights on Earth with our deepest understanding of the universe to reveal how the planet's beauty is created by just a handful of forces. In a perfect combination of accessible science and cutting-edge filming techniques, he explores the simplest possible questions about the planet we live on – such as why is water blue? How can a shape defy gravity? Why do bees make hexagonal honeycombs? – in order to reveal deeper truths about the cosmos and the forces of nature that govern everything in it.
