Part of the new Ladybird Expert series, Quantum Mechanics is a clear, simple and entertaining introduction to the weird, mind-bending world of the very, very small. Written by physicist and broadcaster Professor Jim Al-Khalili, it explores all the key players, breakthroughs, controversies and unanswered questions of the quantum world. You'll discover how the sun shines, why light is both a wave and a particle, the certainty of the Uncertainty Principle, Schrodinger's Cat, Einstein's spooky action, how to build a quantum computer, and why quantum mechanics drives even its experts completely crazy.
