Physics is the oldest and deepest of all the sciences, revealing profound truths about the way in which the Universe operates. Schrödinger’s Cat, the Higgs boson particle, string theory―concepts we’ve all heard of, but how far do we really understand them? Physics Squared guides you through these topics and more. It may have taken us many centuries to realise it, but physical principles underpin all of the other sciences and much of modern technology, making an understanding of basic physics invaluable.

Physics Squared takes you on a whistlestop journey – across 10 chapters and 100 topics, it guides you from the laws of motion and the basic mechanics of the everyday world, through hugely important fields such as electricity and nuclear physics, to the quantum physics and relativity theories that describe the Universe.

With accessible yet authoritative text complimented by new colour illustrations, infographics and photos, Physics Squared is the ideal primer or refresher for those who want to learn more about the science that governs our Universe, to gain a better understanding of how the world we live in works.
