Pendulum

Identifies patterns in the way society judges acceptability, revealing a forty-year cycle in Western society that explains current trends and viewpoints that are shaping the successes of today's political, business, and celebrity figures.

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

Also included are charts for working with homeopathic remedies, herbal teas, to increase health and vitality and number of other alternatives.

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.

The pendulum: a case study in physics is a unique book in several ways. Firstly, it is a comprehensive quantitative study of one physical system, the pendulum, from the viewpoint of elementary and more advanced classical physics, modern chaotic dynamics, and quantum mechanics. In addition, coupled pendulums and pendulum analogs of superconducting devices are also discussed. Secondly, this book treats the physics of the pendulum within a historical and cultural context, showing, for example, that the pendulum has been intimately connected with studies of the earth's density, the earth's motion, and timekeeping. While primarily a physics book, the work provides significant added interest through the use of relevant cultural and historical vignettes. This approach offers an alternative to the usual modern physics courses. The text is amply illustrated and augmented by exercises at the end of each chapter.

This monograph describes the Reaction Wheel Pendulum, the newest inverted-pendulum-like device for control education and research. We discuss the history and background of the reaction wheel pendulum and other similar experimental devices. We develop mathematical models of the reaction wheel pendulum in depth, including linear and nonlinear models, and models of the sensors and actuators that are used for feedback control. We treat various aspects of the control problem, from linear control of themotor, to stabilization of the pendulum about an equilibrium configuration using linear control, to the nonlinear control problem of swingup control. We also discuss hybrid and switching control, which is useful for switching between the swingup and balance controllers. We also discuss important practical issues such as friction modeling and friction compensation, quantization of sensor signals, and saturation. This monograph can be used as a supplement for courses in feedback control at the undergraduate level, courses in mechatronics, or courses in linear and nonlinear state space control at the graduate level. It can also be used as a laboratory manual and as a reference for research in nonlinear control.

The Presbyterian Pendulum is a study in mainline Protestant social ethics with a focus on the Presbyterian Church (USA). This book is written for the church with the hope that it will provide theological foundation and spiritual encouragement for our efforts to find unity despite the diversity of convictions and perspectives in our midst. This is a historical study of the significant social and political issues to which the church responded throughout the twentieth century. With a foundation in solid historical research, this book offers the compelling thesis that the Presbyterian Church is at its best when the wild diversity of worldviews, theological perspectives, and convictions are encouraged. Even more, the book offers the spiritually rich thesis that it is in this wild diversity, not despite of it, that the providence of God is seen and known. What is unique and compelling about this study is the guiding metaphor of the pendulum swinging. The vast difference of opinion in the church around social issues has historically always been true, is necessary today, and itself points to a deeper truth about God's sustaining providence. The church must discern and hold onto that deeper truth. We must let the pendulum swing. It is my hope that this book will be an encouragement for the church even as we continue to be mired in deep conflict.
