Samenvatting:

This book is a popular introduction to the science of motion. It tells the story of mechanics, from Galileo's time to the present day, with an emphasis throughout on surprising phenomena that most challenge our physical intuition.



What makes an aeroplane fly? Why aren't rollercoasters circular? And how long would it take to fall right through the Earth? This wide-ranging popular introduction to the science of motion tells the story of how dynamics developed, from Galileo's time to the present day. Including such exciting discoveries as the motion of the planets, the dynamics of spinning objects, wave motion, elasticity, and fluid mechanics, the book explains the physical phenomena involved, especially those that surprise us and most challenge our elementary intuition. The book brings the fundamental principles of mechanics to life by tackling a wide variety of real-world questions, such as why modern-day loop-the-loop rollercoasters are not circular, why skaters on ice spin faster when they draw in their arms, and how a falling cat, initially upside-down, can sometimes manage to land on its feet. The book also explores the idea that classic problems in mechanics can often acquire a wholly new life by being given a sudden and unexpected modern 'twist', including, for example, the role played by the gravitational three-body problem in the Apollo moon missions of the 1960s. Written in an informal and accessible style, yet underpinned by rigorous scholarship and historical research, this book shows that, even after all these years, classical mechanics still has the potential to surprise us and challenge our understanding of how the world around us really works.
