André Koch Torres Assis, "The Experimental and Historical Foundations of Electricity"
English | 2010 | ISBN: 0986492639 | PDF | pages: 270 | 2 mb
The Experimental and Historical Foundations of Electricity deals with the most fundamental aspects of physics. The book describes the main experiments and discoveries in the history of electricity. It begins with the amber effect, which is analogous to the usual experiment of attracting small pieces of paper with a piece of plastic rubbed in hair. The book explains how to build several instruments: versorium, electric pendulum, electroscope and charge collectors. Electric attraction and repulsion, positive and negative charges, and the ACR mechanism (attraction, communication of electricity, and repulsion) are discussed. The concepts of conductors and insulators, together with the main differences in the behaviours of these two kinds of substances are analyzed. All experiments are clearly described and performed with simple, inexpensive materials. These experiments lead to clear concepts, definitions, and laws describing these phenomena. Historical aspects are presented, together with relevant quotations from the main scientists. The book presents an exhaustive analysis of the work of Stephen Gray (1666-1736), the great British scientist who discovered conductors and insulators, together with some of their main properties. An ample bibliography is included at the end of the work.

Marilyn Morris, "Sex, Money and Personal Character in Eighteenth-century British Politics"
English | ISBN: 0300208456 | 2015 | 288 pages | PDF | 3 MB
How, and why, did the Anglo-American world become so obsessed with the private lives and public character of its political leaders? Marilyn Morris finds answers in eighteenth-century Britain, when a long tradition of court intrigue and gossip spread into a much broader and more public political arena with the growth of political parties, extra-parliamentary political activities, and a partisan print culture. The public's preoccupation with the personal character of the ruling elite paralleled a growing interest in the interior lives of individuals in histories, novels, and the theater. Newspaper reports of the royal family intensified in intimacy and its members became moral exemplars–most often, paradoxically, when they misbehaved. Ad hominem attacks on political leaders became commonplace; politicians of all affiliations continued to assess one another's characters based on their success and daring with women and money. And newly popular human-interest journalism promoted the illusion that the personal characters of public figures could be read by appearances.
Istvan Deak, "Europe on Trial: The Story of Collaboration, Resistance, and Retribution during World War II"
English | ISBN: 0813347890 | 2015 | 256 pages | PDF | 4 MB
In "Europe on Trial," acclaimed historian Istvan Deak explores the history of collaboration, retribution, and resistance during World War II. These three themes are examined through the experiences of people and countries under German occupation, as well as Soviet, Italian, and other military rule. Those under foreign rule faced innumerable moral and ethical dilemmas, including the question of whether to cooperate with their occupiers, try to survive the war without any political involvement, or risk their lives by becoming resisters. Many chose all three, depending on wartime conditions. Following the brutal war, the author discusses the purges of real or alleged war criminals and collaborators, through various acts of violence, deportations, and judicial proceedings at the Nuremberg International Military Tribunal as well as in thousands of local courts. "Europe on Trial" helps us to understand the many moral consequences both during and immediately following World War II. "Foreword by Norman M. Naimark"
The World's Most Evil Gangs by Nigel Blundell

The darkest depths of the organized underworld, from mobsters in the U.S. to Hells Angels in Germany to child armies in Africa Historically, those outside the law have always tended to band together in pursuit of riches and power, eventually spawning the murky, brutal world of today's organized crime discussed here. This book traces the origins of the archetypical, modern gangster to 1920s America, when Prohibition turned street-corner hoodlums into rich and powerful businessmen. From that beginning, highly organized and ferociously protective gangs have become prevalent throughout the world. Despite their despicable methods, we are still fascinated by their labyrinthine networks, and this book reveals how did gangs formed, how they wield their power, how they maintain their secretive societies, and how they evade the massive forces of law and order arrayed against them.
