A three part BBC series

In this series, mathematician Dr Hannah Fry explores the mystery of maths. It underpins so much of our modern world that it is hard to imagine life without its technological advances, but where exactly does maths come from? Is it invented like a language or is it something discovered and part of the fabric of the universe? It's a question that some of the most eminent mathematical minds have been wrestling with. Dr Eleanor Knox from King's College London believes it is discovered, Prof Hiranya Peiris from University College London believes it is invented, while Prof Jim Gates from Brown University believes it is both, and Prof Brian Greene from Columbia University has no idea. The jury is very much divided.

Episode I: Numbers as God (59 min) | ( Click here to watch )

In this episode, Hannah goes back to the time of the ancient Greeks to find out why they were so fascinated by the connection between beautiful music and maths. The patterns our ancestors found in music are all around us, from the way a sunflower stores its seeds to the number of petals in a flower. Even the shapes of some of the smallest structures in nature, such as viruses, seem to follow the rules of maths. All strong evidence for maths being discovered.

But there are those who claim maths is all in our heads and something we invented. To find out if this is true, Hannah has her brain scanned. Then along comes the invention of zero to help make counting more convenient and the creation of imaginary numbers, and the balance is tilted in the direction of maths being something we invented. The question of whether maths is invented or discovered just got a whole lot more difficult to answer.
