Theoretical physics has two theories at its core that are not straightforward to link – quantum mechanics and general relativity. Lee Smolin, one of the world’s greatest living theoretical physicists, has spent his career working out why the theory of quantum mechanics is incomplete and how it might link to general relativity. He is an advocate of versions of quantum loop gravity. His work to marry the two theories resulted in him developing the theory of cosmological natural selection. Join Syma and Tim as they talk to Lee about theoretical physics.

His book is called Einstein's Unfinished Revolution: The Search for What Lies Beyond the Quantum and was published in 2019 by Penguin. https://www.penguin.co.uk/books/269402/einsteins-unfinished-revolution-by-smolin-lee/9780141979168

Biodiversity is under threat, and there are many ongoing efforts to help save it, including from within universities. But are academic contributions doing any good? Our cohost Tim Coulson discussed this topic with Professor Dame EJ Milner-Gulland in the Oxford Martin School (OMS) in April. Thanks to Carlyn Samuel, OMS and the OMS team for hosting the debate and allowing us to record.

Artificial intelligence is a modern-day technology that will impact the way we live much as past innovations like mastering fire, and inventing the printing press, home computers and the internet changed civilisation. But what exactly is it, how does it work, and what are the opportunities and risks of its continued development? We talk to Chris Summerfield about Artificial Intelligence and his fabulous new book, “These Strange New Minds: How AI Learned to Talk and What It Means” recently published by Penguin.
