A guide to everything you need and want to know about quantum physics, how our universe works and our existence in it. Quantum physics is the most cutting-edge, important and fascinating area of modern science. We have all heard of Einstein's theory of relativity and Schrodinger's Cat - but do we really understand the mind-bending theories of our universe?In 50 concise chapters, Joanne Baker covers the foundation concepts of quantum physics and moves on to present clear explanations of complex theories and their advanced applications - from string theory to black holes, and quarks to quantum computing. With informative two-colour illustrations alongside key ideas in straightforward, bite-sized chunks, this book will teach you everything you need to know about quantum physics - and challenge the way you understand the world. The ideas explored include: Theory of relativity; Schrödinger's cat; Nuclear forces: fission and fusion; Antimatter; Superconductivity.
