Constructor theory holds promise for revolutionising the way fundamental physics is formulated and for providing essential tools to face existing technological challenges. Chiara's book "The Science of Can and Can't" is available now: https://geni.us/ChiaraMarletto Watch the Q&A: https://youtu.be/q9hCRLCLztI Physicist Chiara Marletto proposes a new way of thinking about laws of nature. Thinking about which laws are possible or impossible may generate an alternative way of providing explanations, and therefore new scientific theories. In this talk, Chiara is in-conversation with Marcus du Sautoy to explain this fascinating, far-reaching approach (known as Constructor Theory) which holds promise for revolutionising the way fundamental physics is formulated and for providing essential tools to face existing technological challenges, from delivering the next generation of information-processing devices beyond the universal quantum computer to designing AIs. Chiara Marletto is a Research Fellow working at the Physics Department, University of Oxford. Within Wolfson, she is an active member of the Quantum Cluster and of the New Frontiers Quantum Hub. Her research is in theoretical physics, with special emphasis on Quantum Theory of Computation, Information Theory, Thermodynamics, Condensed-Matter Physics and Quantum Biology. Some of her recent research has harnessed a recently proposed generalisation of the quantum theory of information — Constructor Theory — to address issues at the foundations of the theory of control and causation in physics. These include applications to defining general principles encompassing classical, quantum and post-quantum theories of information; and to assessing the compatibility of essential features of living systems, such as the ability to self-reproduce and evolve, with fundamental laws of Physics, in particular with Quantum Physics. They also include the definition of a new class of witnesses of non-classicality in systems that need not obey quantum theory, such as gravity; and a scale-independent definition of irreversibility, work and heat, based on constructor-theoretic ideas. Marcus du Sautoy is the Charles Simonyi Professor for the Public Understanding of Science at the Oxford University, a chair he holds jointly at the Department of Continuing Education and the Mathematical Institute. He is also a Professor of Mathematics and a Fellow of New College. He was made a Fellow of the Royal Society in 2016. In 2006 he gave the CHRISTMAS LECTURES, entitled THE NUM8ER MY5TERIES. This talk was filmed on 27 May 2021. --- A very special thank you to our Patreon supporters who help make these videos happen, especially: Abdelkhalek Ayad, Martin Paull, Anthony Powers, Ben Wynne-Simmons, Ivo Danihelka, Hamza, Paulina Barren, Metzger, Kevin Winoto, Jonathan Killin, János Fekete, Mehdi Razavi, Mark Barden, Taylor Hornby, Rasiel Suarez, Stephan Giersche, William 'Billy' Robillard, Scott Edwardsen, Jeffrey Schweitzer, Gou Ranon, Christina Baum, Frances Dunne, jonas.app, Tim Karr, Adam Leos, Michelle J.
