The Nine Lives of Schrödinger's Cat
Quantum theory's predictions are clear, but its physical interpretation is not. IAI News invited nine physicists and philosophers to explain their interpretation of the Schrödinger's cat thought experiment. One interpretation of quantum mechanics called "QBism" focuses on the beliefs of the observer rather than the physical reality of the object being observed. Amanda Gefter interviewed the founder of QBism, Christopher Fuchs, for Quanta in 2015.

Good News for the Scatterbrained
Studying the entropy produced during various brain activities could lead to insights about how the mind works. Morten Kringelbach and Gustavo Deco write for Aeon about their thermodynamic theory of the mind. The neuroscientist Anil Seth also sees a connection between thermodynamics and the brain: He believes the brain actively fights against the 2nd law of thermodynamics by using predictive models to keep tight control over its processes.
