Book Description
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.

Book Description
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.

Book Description
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

Book Description
You have one chance. Run. "ONE OF THE BEST THRILLERS OF THE YEAR" -- JAMES PATTERSON, bestselling author. Photojournalist John Wallace struggles to consciousness to find he has been bound and blindfolded by a masked man who is preparing to hang him in his own living room. Forced onto a chair with a noose around his neck, Wallace briefly reconsiders his mostly lonely life before the chair is kicked out beneath him and his world fades to black. Then he gets lucky and manages to escape his apartment, just ahead of his assailant. Bloody, barefoot, and with at least one broken rib, he has no choice but to run for his life. When his would-be killer strikes again, Wallace realizes he will have to figure out who is hunting him and stop him on his own. The pendulum of fate swung briefly in his favor, but it's only a matter of time before its momentum carries it to the other side . . .

Book Description
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.

Book Description
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.
