If you think numbers are just about sitting in a boring maths lesson, then think again. Johnny Ball is back! Numbers are eternal and have been a crucial element in human history, scientific discovery, and adventure. Mathmagicians carries on the mathematical escapades of number-crunchers throughout history. Starting in ancient times we explore the birth of measurement -- from time, weight, and distance to how great thinkers believed in the magic of numbers. Through the ages, from ancient times to the Renaissance and into the Industrial age, Mathmagicians examines how numbers have allowed explorers, engineers, and scientists to explore, build, and discover. From sailing the seven seas to journeying deep below the waves and up through the atmosphere, it's all about numbers. Discover how integral measurement is to simple modern-day things and see how the future will be shaped by numbers as we travel farther into space and beyond.
