Immense, strange and infinite, the world of modern physics often feels impenetrable to the undiscerning eye – a jumble of muons, gluons and quarks, impossible to explain without several degrees and a research position at CERN. But it doesn’t have to be this way! Allow world-renowned theoretical physicist and bestselling author Sean Carroll to guide you through the biggest ideas in the universe. Elegant and simple, Carroll unravels this web of theories and formulae equation by equation, getting to the heart of the truths they represent. In the first book of this landmark trilogy, Carroll delves into the core of classical physics. From Euclid to Einstein, this book explores the ideas which revolutionised science and forever changed our understanding of our place in the cosmos.
