Explore the laws and theories of physics in this accessible introduction to the forces that shape our universe, our planet, and our everyday lives.

Using a bold, graphics-led approach, The Physics Book sets out more than 80 of the key concepts and discoveries that have defined the subject and influenced our technology since the beginning of time. With the focus firmly on unpacking the thought behind each theory-as well as exploring when and how each idea and breakthrough came about-five themed chapters examine the history and developments in specific areas such as Light, Sound, and Electricity.

Eureka moments abound: from Archimedes' bathtub discoveries about displacement and density, and Galileo's experiments with spheres falling from the Tower of Pisa, to Isaac Newton's apple and his conclusions about gravity and the laws of motion. You'll also learn about Albert Einstein's revelations about relativity; how the accidental discovery of cosmic microwave background radiation confirmed the Big Bang theory; the search for the Higgs boson particle; and why most of the universe is missing. If you've ever wondered exactly how physicists formulated-and proved-their abstract concepts, The Physics Book is the book for you.
