Event description

Quantum physics is not mystifying. Its implications may be mind-bending, and not yet fully understood, but the theory is illuminating. It is the best explanation of reality we have. And no, God does not play dice with the universe.

This talk spans the history of quantum discoveries, from Einstein and Bohr to the present day, guiding you through the most intriguing subject in science.

Sean M Carroll will debunk the myths that have grown up around quantum physics, resurrect and reinstate the Many-Worlds Interpretation, and present a new path to solving the apparent conflict between quantum mechanics and gravity.

About the speakers

Sean M Carroll is a theoretical physicist, specializing in quantum mechanics, gravitation, cosmology, statistical mechanics, and foundations of physics, with occasional dabblings elsewhere. His official titles are Research Professor of Physics at Caltech and Research Professor at the Santa Fe Institute. He lives in Los Angeles with his wife, writer Jennifer Ouellette.

His newest book, 'Something Deeply Hidden', is about quantum mechanics, Many Worlds, and the emergence of spacetime. He recently started a podcast, 'Mindscape', where he interviews smart people about interesting ideas.

The event will be introduced by Flora GrahamFlora is a science journalist who writes a daily email newsletter for Nature, the world's leading science journal. She has written for New Scientist, the BBC, CBC, and CNET, among others and specialises in physics and technology.


The doors will open at approximately 6.30pm, with a prompt start at 7.00pm. There will be time for questions after the talk.

Latecomers will be admitted into the gallery.

Book signing

Copies of Sean's book, 'Something deeply hidden', will be available for purchase and signing after the event.
