For years, scientists adhered to the physics of Sir Isaac Newton. Over time, however, they discovered that Newtonian physics couldn''t describe every phenomenon they observed. They developed a new model, called quantum physics, which described the universe in a fundamentally new way, in terms of quanta and fields. Its revolutionary concepts, including wave-particle duality, randomness, and quantum jumps, are explained in this book in easy-to-follow language. The text examines the gaps in classical physics that spurred the search for new theories, the discoveries that shaped those theories, and the scientists who developed this exciting field. This volume also explores the ongoing ramifications of quantum physics in our lives today.
