The geometry of chaos can explain our uncertain world, from weather and pandemics to quantum physics and free will.
This talk was recorded at the Ri on 21 April 2023.
Join Tim Palmer as he explores how it provides the means to predict the world around us, and provides new insights into some of the most astonishing aspects of our universe and ourselves.

Tim Palmer is a Royal Society Research Professor in the Department of Physics at the University of Oxford. Following a PhD in general relativity theory, he spent much of his career working on the predictability and dynamics of weather and climate, developing probabilistic ensemble prediction systems across a range of weather and climate timescales. He also researches the foundations of quantum physics, in addition to applications of quantum and imprecise computing. He is a Fellow of the Royal Society and an International Member of the US National Academy of Sciences. Amongst other awards, he has won the Institute of Physics Dirac Gold Medal, and the top medals of the American and European Meteorological Societies.
