Politics, manners, humor, sexuality, wealth, even our definitions of success are periodically renegotiated based on the new values society chooses to use as a lens to judge what is acceptable. Are these new values randomly chosen or is there a pattern? Pendulum chronicles the stuttering history of western society; that endless back-and-forth swing between one excess and another, always reminded of what we left behind. There is a pattern and it is 40 years: 2003 was a fulcrum year, as was 1963, its opposite. Pendulum explains where we have been as a society, how we got here, and where we are headed. If you would benefit from a peek into the future, you would do well to read this book.
Chris, a young man, stands next to an elderly grounds keeper, in an old Virgina cemetery. He is telling a remarkable story of the connection of two graves that lay before them. Chris' father, Ben, a retired deputy sheriff, was seriously wounded while employed as a security guard for a very high end research institute. Due to his serious, dimensioning condition, he is used in an experiment that produces strange, unexpected results which subsequently changes the lives of those around him. No one could know the journey Ben would take until almost a year later when the experiment comes to a crescendo that led to unbelievable discoveries.
This gripping memoir traces Brazilian-born American Julie Lindahl's journey to uncover her grandparents' roles in the Third Reich as she is driven to understand how and why they became members of Hitler's elite, the SS. Out of the unbearable heart of the story--the unclaimed guilt that devours a family through the generations--emerges an unflinching will to learn the truth. In a remarkable six-year journey through Germany, Poland, Paraguay, and Brazil, Julie uncovers, among many other discoveries, that her grandfather had been a fanatic member of the SS since 1934. During World War II, he was responsible for enslavement and torture and was complicit in the murder of the local population on the large estates he oversaw in occupied Poland. He eventually fled to South America to evade a new wave of war-crimes trials. The pendulum used by Julie's grandmother to divine good from bad and true from false becomes a symbol for the elusiveness of truth and morality, but also for the false securities we cling to when we become unmoored. As Julie delves deeper into the abyss of her family's secret, discovering history anew, one precarious step at a time, the compassion of strangers is a growing force that transforms her world and the way that she sees her family--and herself.
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)
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
In 1851, struggling, self-taught physicist Léon Foucault performed a dramatic demonstration inside the Panthéon in Paris. By tracking a pendulum's path as it swung repeatedly across the interior of the large ceremonial hall, Foucault offered the first definitive proof -- before an audience that comprised the cream of Parisian society, including the future emperor, Napoleon III -- that the earth revolves on its axis. Through careful, primary research, world-renowned author Amir Aczel has revealed the life of a gifted physicist who had almost no formal education in science, and yet managed to succeed despite the adversity he suffered at the hands of his peers. The range and breadth of Foucault's discoveries is astonishing: He gave us the modern electric compass, devised an electric microscope, invented photographic technology, and made remarkable deductions about color theory, heat waves, and the speed of light. Yet until now so little has been known about his life. Richly detailed and evocative, Pendulum tells of the illustrious period in France during the Second Empire; of Foucault's relationship with Napoleon III, a colorful character in his own right; and -- most notably -- of the crucial triumph of science over religion. Dr. Aczel has crafted a fascinating narrative based on the life of this most astonishing and largely unrecognized scientist, whose findings answered many age-old scientific questions and posed new ones that are still relevant today.
As new presidential administrations come into power, they each bring their own approach to foreign policy. No grand strategy, however, is going to be completely novel. New administrations never start with a blank slate, so it is always possible to see similarities between an administration and its predecessors. Conversely, since each administration faces novel problems and operates in a unique context, no foreign policy strategy is going to be an exact replica of its predecessors. In American Pendulum, Christopher Hemmer examines America's grand strategic choices between 1914 and 2014 using four recurring debates in American foreign policy as lenses. First, how should the United States balance the trade-offs between working alone versus working with other states and international organizations? Second, what is the proper place of American values in foreign policy? Third, where does the strategic perimeter of the United States lie? And fourth, is time on the side of the United States or of its enemies?Offering new readings of debates within the Wilson, Truman, Nixon, Bush, and Obama administrations, Hemmer asserts that heated debates, disagreements, and even confusions over U.S. grand strategy are not only normal but also beneficial. He challenges the claim that uncertainties or inconsistences about the nation's role in the world or approach to security issues betray strategic confusion or the absence of a grand strategy. American foreign policy, he states, is most in danger not when debates are at their most pointed but when the weight of opinion crushes dissent. As the United States looks ahead to an increasingly multipolar world with increasing complicated security issues, Hemmer concludes, developing an effective grand strategy requires ongoing contestation and compromises between competing visions and policies.
This volume chronicles the horological work carried out in France, Germany, and North America and completes the fascinating history of precision timekeeping in recent time. Over 500 beautiful color and black-and-white photographs illustrate the historical contributions of renowned clockmakers from France and Germany. America's contribution to precision timekeeping is chronicled along with recent advancements in precision pendulum timekeeping.
