A stimulating and highly readable introduction to the science of imperfections, this book focuses on their crucial role in technology, as well as their influence on society, love, life, health, politics, career development, and key environmental issues, enabling readers to counteract scientific misinformation.

Résumé
It may be surprising to focus on and praise imperfection, but, in reality, perfection is a fiction. Every aspect of our technologies is based on understanding and exploiting imperfections in the materials we use. Imperfections are key to our use of metals, glass, electronics, computers, optical fibres, and building materials. Catalysis, as used throughout chemical industries, is dependent on imperfections, as are a wide range of modern advances in biology and medicine. This book provides examples in each area that are readily understandable to non-scientists but also aim to offer a far deeper insight into how the technologies and disciplines advance and operate. However, once we change our focus from idealised perfection to reality, the implications can extend far beyond the realm of the sciences. The second part of the book examines the importance of our ability to recognise and adapt to imperfections in such wide-ranging areas as cookery, successful career development, love, life, and the survival of humanity. Using a broad range of accessible examples, this book aims to give readers the tools to recognize technological imperfections and apply those lessons to improving several key aspects of our lives, crucially enabling them to define a world that will survive current excesses and environmental destruction.
