Constructor theory is a relatively nascent idea in fundamental physics that proposes to underlie all other currently known theories, not to mention those yet to be known, and to solve problems across a host of fields in science and beyond. Logan Chipkin joins Oxford physicist and constructor theorist Chiara Marletto to discuss what constructor theory is, how it might point the way to a successor to quantum theory, and how it might allow physics to tackle some of philosophy’s most perplexing puzzles.  Link to interview transcript.  Link for interview video.
