The pendulum is a universal topic in primary and secondary schools, but its full potential for learning about physics, the nature of science, and the relationships between science, mathematics, technology, society and culture is seldom realised. Contributions to this 32-chapter anthology deal with the science, history, methodology and pedagogy of pendulum motion. There is ample material for the richer and more cross-disciplinary treatment of the pendulum from elementary school to high school, and through to advanced university classes. Scientists will value the studies on the physics of the pendulum; historians will appreciate the detailed treatment of Galileo, Huygens, Newton and Foucault’s pendulum investigations; psychologists and educators will learn from the papers on Piaget; teachers will welcome the many contributions to pendulum pedagogy. All readers will come away with a new awareness of the importance of the pendulum in the foundation and development of modern science; and for its centrality in so many facets of society and culture.

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 time pieces--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 sound and light to the astonishing intersection of the pendulum's oscillations and quantum theory, resulting in new insight into the make-up of the material universe. Covering topics from the invention of time zones to Isaac Newton's equations of motion, from Pythagoras' theory of musical harmony to Michael Faraday's field theory and the development of quantum electrodynamics, Galileo's Pendulum is an authoritative and engaging tour through time of the most basic all-pervading system in the world.

This monograph is concerned with modeling and control of a novel inverted pendulum device known as the Reaction Wheel Pendulum. The Reaction Wheel Pendulum is perhaps the simplest of the various pendulum systems in terms of its dynamic properties. At the same time, the Reaction Wheel Pendulum exhibits several properties, such as underactuation and nonlinearity that make it an attractive and useful system for research and advanced education. As such, the Reaction Wheel Pendulum is ideally suited for educating engineering students at virtually every level, from freshman to advanced graduate students.
It is the year 25 A.G. Universal Government now regulates every facet of every person's daily living from conception to death. This is done by a team of specialists in every field and electronically monitored 24 hours a day for any deviations from what is defined as the "norm." But, Murphy's Law is proven once again. One man and one woman manage to bite the apple without being detected until the sin had been accomplished. When discovered-they were required to plead their own defense while the entire world tuned in. Their thoughts, while listening, were all fed into CAM, the Supreme Computer. Upon the termination of their defenses, CAM orders all computers to self destruct immediately. Men and women would then revert to human contact without government regulation thus allowing their God given love to return as the regulator of their lives. And I quote, "When man changes the love of power for the power of love, peace will reign."
Three book editors, jaded by reading far too many crackpot manuscripts on the mystic and the occult, are inspired by an extraordinary conspiracy story told to them by a strange colonel to have some fun. They start feeding random bits of information into a powerful computer capable of inventing connections between the entries, thinking they are creating nothing more than an amusing game, but then their game starts to take over, the deaths start mounting, and they are forced into a frantic search for the truth

From the May, 1999 American Society for Testing and Materials conference of the same name come 23 papers (two of which weren't actually presented at the conference) examining the benefits and pitfalls of the Charpy impact test and some alternative methods, in particular instrumented impact testing. The broad topics treated are the background of impact testing; reference energies, machine stability, and calibration; impact test procedures, and fracture toughness assessment from impact test data.

Gain experience and develop skills for a confident future practice. An excellent introduction to this age-old divination technique.
1955 to the average man or woman, the use of a pendulum or diving rod is completely new and mystifying. But in reality, it is one of the oldest sciences known to man, with many references to the use of rods and pendulums found throughout history. Stell.
