How geometry created modern physics – with Yang-Hui He

From the creator

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: https://youtu.be/taB75bCk8J0 Subscribe for regular science videos: http://bit.ly/RiSubscRibe 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). Discourses are one of the Ri’s oldest and most prestigious series of talks. Since 1825, audiences in the theatre have witnessed countless mind-expanding moments, including the first public liquefaction of air by James Dewar, the announcement of the electron by JJ Thomson and over 100 lectures by Michael Faraday. In more recent times, we have had Nobel laureates, Fields medal winners, scientists, authors and artists – all from the cutting-edge of their field. Discourses are an opportunity for the best and brightest to share their work with the world. Steeped in nearly two centuries of tradition, a Disco
