How geometry created modern physics with Yang-Hui He

What's the story behind the five axioms of Euclidean geometry - and how is post-Euclidean geometry linked to modern physics? Watch the Q&A with Yang-Hui He here: Subscribe for regular science videos: From geometry’s classical beginnings, via the Renaissance and the Enlightenment, to the present day, Yang-Hui He takes us on a journey through time and space, culminating in our understanding of spacetime itself. In the 19th century, mathematicians such as Carl Gauss and Bernhard Riemann considered what would happen if we relaxed Euclid’s axioms. The result was the explosion of post-Euclidean geometry, which paved the way for Einstein’s theory of relativity and the birth of modern physics. -- This Discourse was filmed at the Ri on 24 February 2023, in partnership with the London Institute for Mathematical Sciences (LIMS).
