Despite their apparent simplicity, the behaviour of pendulums can be remarkably complicated. Historically, pendulums for specific purposes have been developed using a combination of simplified theory and trial and error. There do not appear to be any introductory books on pendulums, written at an intermediate level, and covering a wide range of topics. This book aims to fill the gap. It is written for readers with some background in elementary geometry, algebra, trigonometry and calculus. Historical information, where available and useful for the understanding of various types of pendulum and their applications, is included. Perhaps the best known use of pendulums is as the basis of clocks in which a pendulum controls the rate at which the clock runs. Interest in theoretical and practical aspects of pendulums, as applied to clocks, goes back more than four centuries. The concept of simple pendulums, which are idealised versions of real pendulums is introduced. The application of pendulums to clocks is described, with detailed discussion of the effect of inevitable differences between real pendulums and simple pendulums. In a clock, the objective is to ensure that the pendulum controls the timekeeping. However, pendulums are sometimes driven, and how this affects their behaviour is described. Pendulums are sometimes used for occult purposes. It is possible to explain some apparently occult results by using modern pendulum theory. For example, why a ring suspended inside a wine glass, by a thread from a finger, eventually strikes the glass. Pendulums have a wide range of uses in scientific instruments, engineering, and entertainment. Some examples are given as case studies. Indexed in the Book Citation Index– Science (BKCI-S)

The blackness of eternal night encompassed me. The intense darkness oppressed and stifled me so that I struggled for breath.Having been condemned to death by the Spanish Inquisition, the narrator descends into a kind of hell. Dizzy with weakness and fainting with fear, he experiences such torments that death itself would be welcome. What troubles him most is the eternal question: how will he die?Toledo Prison is notorious for the torture of the condemned. What minds have dreamed up the terror of the pit in the center of the cell? What is the significance of the painted figure of Time with his menacing pendulum? Why do the walls glow with heat?Experience with the narrator the intensity of his suffering when death seems inevitable but its form uncertain. Can anything, or anybody, help him?

"The Mechanics of Mechanical Watches and Clocks" presents historical views and mathematical models of mechanical watches and clocks. Although now over six hundred years old, mechanical watches and clocks are still popular luxury items that fascinate many people around the world. However few have examined the theory of how they work as presented in this book. The illustrations and computer animations are unique and have never been published before. It will be of significant interest to researchers in mechanical engineering, watchmakers and clockmakers, as well as people who have an engineering background and are interested in mechanical watches and clocks. It will also inspire people in other fields of science and technology, such as mechanical engineering and electronics engineering, to advance their designs. Professor Ruxu Du works at the Chinese University of Hong Kong, China. Assistant Professor Longhan Xie works at the South China University of Technology, China.

Machines have always gone hand-in-hand with the cultural development of m- kind throughout time. A book on the history of machines is nothing more than a specific way of bringing light to human events as a whole in order to highlight some significant milestones in the progress of knowledge by a complementary persp- tive into a general historical overview. This book is the result of common efforts and interests by several scholars, teachers, and students on subjects that are connected with the theory of machines and mechanisms. In fact, in this book there is a certain teaching aim in addition to a general historical view that is more addressed to the achievements by “homo faber” than to those by “homo sapiens”, since the proposed history survey has been developed with an engineering approach. The brevity of the text added to the fact that the authors are probably not com- tent to tackle historical studies with the necessary rigor, means the content of the book is inevitably incomplete, but it nevertheless attempts to fulfil three basic aims: First, it is hoped that this book may provide a stimulus to promote interest in the study of technical history within a mechanical engineering context. Few are the co- tries where anything significant is done in this area, which means there is a general lack of knowledge of this common cultural heritage.

This is the second volume of a series of edited books whose aim is to collect c- tributed papers within a framework that can serve as a collection of persons in MMS (Mechanism and Machine Science). This is a continuation of the first volume that was published in 2008, again combining very ancient and very recent scholars in order to give not only an encyclopaedic character to this project but also to emphasize the significance of MMS over time. This project has the characteristic that the papers illustrate, by recognizing p- sons and their scientific work, mainly technical developments in the historical evolution of the fields that today are grouped in MMS. Thus, emphasis is also given to biographical notes describing efforts and experiences of people who have c- tributed to the technical achievements whose technical survey is the core of each contributed paper. This second volume of the project has been possible thanks to the invited authors who have enthusiastically shared in this initiative and who have spent time and effort in preparing the papers. The stand-alone papers cover the wide field of the History of Mechanical Engineering with specific focus on MMS. I believe that readers will take advantage of the papers in this book and future ones by supplying further satisfaction and motivation for her or his work (historical or not).

This book focuses on the way in which the problem of the motion of bodies has been viewed and approached over the course of human history. It is not another traditional history of mechanics but rather aims to enable the reader to fully understand the deeper ideas that inspired men, first in attempting to understand the mechanisms of motion and then in formulating theories with predictive as well as explanatory value. Given this objective, certain parts of the history of mechanics are neglected, such as fluid mechanics, statics and astronomy after Newton. On the other hand, due attention is paid, for example, to the history of thermodynamics, which has its own particular point of view on motion. Inspired in part by historical epistemology, the book examines the various views and theories of a given historical period (synchronic analysis) and then makes comparisons between different periods (diachronic analysis). In each period, one or two of the most meaningful contributions are selected for particular attention, instead of presenting a long inventory of scientific achievements.

Bored with their work, three Milanese editors cook up "the Plan," a hoax that connects the medieval Knights Templar with other occult groups from ancient to modern times. This produces a map indicating the geographical point from which all the powers of the earth can be controlled—a point located in Paris, France, at Foucault’s Pendulum. But in a fateful turn the joke becomes all too real, and when occult groups, including Satanists, get wind of the Plan, they go so far as to kill one of the editors in their quest to gain control of the earth. Orchestrating these and other diverse characters into his multilayered semiotic adventure, Eco has created a superb cerebral entertainment.
