Book excerpt: Quantum physics helps explain many mysteries of the universe. It underpins everything, but it need not be quantum difficult with this informative, accessible, easy-to-follow guide to the fundamentals and concepts of quantum physics and our quantum universe! Quantum physics is all around us. It’s in electrical lights, lasers, and the color of the sky. Without it, the sun wouldn’t shine. It even explains how human eyes work. With its role in photosynthesis, it literally supports life. Yet, it had Schrödinger wondering whether his cat was alive or dead. It tells us that something can be both a wave and a particle and that two linked particles can communicate across the universe instantaneously! And it might even explain how the multiverse is real. Quantum physics is the key to understanding our complex world, yet even our most brilliant minds haven’t figured it all out yet. Engaging and approachable, The Handy Quantum Physics Answer Book helps untangle this complex subject, making quantum physics and its impact on us, the world, and the universe entertaining and easy to grasp. From the basics to the theories and from the practical applications to the future, this illuminating book answers more than 800 fascinating questions so you can easily understand quantum physics, including ... Did the Big Bang arise from quantum foam? When did philosophers first consider the existence of atoms? What is the largest nuclear weapon ever detonated? What are quarks? What is quantum teleportation? What is the Heisenberg Uncertainty Principle? What is the quantum principle used in MRI machines? Does entangled time mean the present can affect the past? Why did Albert Einstein say, “God does not play dice with the universe”? How is a black hole a quantum object? How does quantum physics appear in portrayals of space? Do we live in a multiverse?
