Expanded Horizons: Adding to the case that math was discovered, Hannah travels down the fastest zip line in the world to learn more about Newton's thoughts on gravity and examines the work of James Clerk Maxwell, who unified the ideas of electricity and magnetism. But the 19th-century creation of new types of geometry argues for math being invented, as does Georg Cantor's theories on the different sizes of infinity.
