Professor Marcus du Sautoy reveals a hidden numerical code that underpins all nature. A code that has the power to explain everything, from the numbers and shapes we see all around us to the rules that govern our own lives

Starting at the hexagonal columns of Northern Ireland’s Giant’s Causeway, Marcus discovers the code underpinning the extraordinary order found in nature - from rock formations to honeycomb and from salt crystals to soap bubbles.

Marcus enters the strange world of what happens next. His odyssey starts with the lunar eclipse – once thought supernatural, now routinely predicted through the power of the code.
