Downward Causation. Cosmologist George Ellis investigates agency and argues that causation is a two-way process between the mind and lower level biological and physical functions. From the 6th FQXi m…
Designing the Mind. Cognitive scientist Susan Schneider talks transhumanism and asks at what point does human enhancement go too far? Are we in danger of accidentally destroying ourselves through tec…
Measuring Free Will. To what degree are our choices really free, rather than determined? And how much control do we have over them? Quantum physicist Ian Durham presents a new mathematical model for …
How do we make decisions? Physicist Carlo Rovelli discusses the science behind choice -- arguing that agency is intimately tied to time's arrow. From the 6th FQXi meeting in Tuscany.
Building an AI Physicist. Cosmologist Max Tegmark describes the challenges with creating trustworthy artificial intelligence, and his own project writing a code that used neural networks to re-discov…
The Limits of Computation. Astrophysicist Fred Adams argues the world will run out of resources for computation in 32 years without a paradigm shift. And he discusses how alien civilizations could mi…
Causality, Memory and the Arrow of Time. Cosmologist Sean Carroll is searching for a mathematical description of why causes precede effects and asking what makes our memories of the past special. Aud…
