The world of quantum physics is an amazing place, where quantum particles can do weird and wonderful things, acting totally unlike the objects we experience in day-to-day life. How can atoms exist in two places at once? And just how can a cat be dead and alive at the same time? Find out more with this entertaining illustrated guide to the fascinating, mysterious world of quantum physics. Topics include: quanta, light, waves and particles, mass, photons, atoms, molecules, spectra, wave-particle duality, matter and antimatter, Schrödinger’s cat, the Uncertainty Principle, probability waves, quantum entanglement, radioactivity and quarks.
