The Universe in Your Hand
A Journey Through Space, Time and Beyond
As he sets off to conduct a journey through the universe, the astrophysicist Christophe Galfard aims to ‘not leave any readers behind’ and promises to use only one equation (E=mc²). In a widely acclaimed, non-scientists’ introduction to modern physics and cosmology, Galfard uses humour, storytelling and thought experiments to make concepts such as electromagnetism, quantum mechanics, general relativity and black holes intelligible to all of us.
