Geometry: From Land Measurement to Understanding the Universe

This episode of the podcast 'The Joy of Why' features theoretical physicist Yang-Hui He discussing the evolution of geometry. From its ancient roots in land measurement and pyramid construction to its pivotal role in Einstein's general relativity, geometry's influence is explored. He argues that geometry serves as a unifying language for modern physics and speculates on AI's potential to revolutionize the field. The hosts also discuss the tension between formal mathematics and intuition-driven insight, and the two types of mathematicians: 'birds' and 'hedgehogs'.
