How do you build a machine too small to see, and why did the Nobel committee compare it to the Wright brothers' first flight? In 2016, three chemists won the prize for making working engines from single molecules. This book tells their story in vivid, jargon-free prose. It will delight curious readers who love science, wonder at the very small, and want to know what comes after the smartphone age.
Readers will discover how Jean-Pierre Sauvage used a copper ion to link molecular rings into chains held together without a single chemical weld. They will see how Fraser Stoddart threaded rings onto axles and made them shuttle on command, and how Ben Feringa built a light-driven motor that spins in only one direction. Along the way, they will enter a jostling world where heat shakes everything and direction must be paid for with fuel.
What makes this book special is its central argument: these are not imitations of life's proteins but a technology designed from a blank page. Compact, accessible, and honest about what remains experimental, it explains the chemistry without equations and points toward medicine, smart materials, and future machines.
