Forces of Nature with Brian Cox - Season 1 Episode 1

Professor Cox tries to explain how the fundamental forces of nature, especially gravity, shape realty into the tiniest details, even what seems as random as the endless variation among snowflakes. He also shows with Catalonia's traditional human pyramids and the hexagonal basic shape of bee hives -to store honey which is perilously harvested in the Himalayas- how geometry vitally distributes forces.
