Magic Numbers - Hannah Frys Mysterious World of Maths - 02 - Expanded Horizons 720p

In this episode, Hannah learns more about Newton's ideas on gravity. His discoveries revealed the movement of the planets was regular and predictable. Evidence for maths being discovered.

If maths is more like a game, albeit a complicated one, where we can change the rules, surely this points to maths being something we invent - a product of the human mind.
