Weirder and Weirder

Hannah concludes that while we have invented the language of maths, the structure behind it all is something we discover

Expanded Horizons

In this episode, Hannah travels down the fastest zip wire in the world to learn more about Newton’s ideas on gravity. His discoveries revealed the movement of the planets was regular and predictable. James Clerk Maxwell unified the ideas of electricity and magnetism and explained what light was.  As if that wasn’t enough he also predicted the existence of radio waves. His tools of the trade were nothing more than pure mathematics. All strong evidence for maths being discovered. 

But in the 19thcentury, maths is turned on its head when new types of geometry are invented. No longer is the kind of geometry we learned in school the final say on the subject. 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. 

To try and answer this question, Hannah travels to Halle in Germany on the trail of perhaps one of the greatest mathematicians of the 20thcentury Georg Cantor. He showed that infinity, far from being infinitely big actually comes in different sizes, some bigger than others. This increasingly weird world is feeling more and more like something we’ve invented. But if that’s the case, why is maths so uncannily good at predicting the world around us. Invented or discovered, this question just got a lot harder to answer.
