Mathematician Dr. Hannah Fry explores the mystery of math. It underpins so much of our modern world that it's hard to imagine life without its technological advances, but where does math come from? In this episode, Hannah explores a paradox at the heart of modern math, discovered by Bertrand Russell. These flaws suggest that math is not a true part of the universe but might be a human language. Hannah argues that Einstein's theoretical equations and theory of general relativity are so good at predicting the universe, they must reflect some basic structure. She then explores what math can reveal about the fundamental building blocks of the universe-the subatomic, quantum world.
