Overview

Bored during Mass at the cathedral in Pisa, the seventeen-year-old Galileo regarded the chandelier swinging overhead - and remarked, to his great surprise, that the lamp took as many beats to complete an arc when hardly moving as when it was swinging widely. Galileo's Pendulum tells the story of what this observation meant, and of its profound consequences for science and technology. The principle of the pendulum's swing - a property called isochronism - marks a simple yet fundamental system in nature, one that ties the rhythm of time to the very existence of matter in the universe. Roger Newton sets the stage for Galileo's discovery with a look at biorhythms in living organisms and at early calendars and clocks - contrivances of nature and culture that, however adequate in their time, did not meet the precise requirements of seventeenth-century science and navigation. Galileo's Pendulum recounts the history of the newly evolving timepieces - from marine chronometers to atomic clocks - based on the pendulum as well as other mechanisms employing the same physical principles, and explains the Newtonian science underlying their function. The book ranges nimbly from the sciences of sou

This delightful short book addresses the problem of time measurement, viewed in its different aspects through history. It is centered on the keen observation made anecdotally in the cathedral of Pisa by Galileo Galilei, when he was only 17, that the time it took the hanging chandelier to complete one oscillation was independent of how far it was swinging...The far-reaching and pervading properties of the harmonic oscillator are presented clearly and concisely as a crucial building block for our understanding of nature in this very interesting and engaging book. -- Germaine Cornelissen Key Reporter
