Every day we need reliable ways of measuring length, weight and time. For most of human history these were based on creatively improvised local standards, such as the ancient Chinese connection between length and musical pitch. This book, by the philosopher who writes a regular Physics World column, tells little-known stories behind the world’s diverse measures and shows how they were gradually consolidated into a universal system, and how scientists are creating the first absolute system based on physical constants.
