"The 20th century was the interaction of geometry and physics, and the 21st century is the interaction of number theory with physics." This intriguing insight comes from our recent discussion with Yang-Hui He from the London Institute of Mathematical Sciences. Yang told us an amazing story about the flow of ideas between mathematics and physics, that involves some of the most celebrated achievements in the last century.

You can find out more about the ideas we discussed with Yang in this podcast in the accompanying articles String theory: A promise from physics and String theory: Convincing mathematics. And stay tuned for the second part of our conversation with Yang in the next episode!

We were speaking to Yang about a research programme, Black holes: bridges between number theory and holographic quantum information, held at the Isaac Newton Institute for Mathematical Sciences in Cambridge. The programme brought together a fascinating array of experts in black holes and quantum theory, with mathematicians and computer scientists. You can read more in our coverage of the programme here.
