Archimedes, the center of gravity, and the first law of mechanics by André Koch Torres Assis( )

12 editions published between 2008 and 2010 in English and Portuguese and held by 1,584 WorldCat member libraries worldwide

Publisher's description: Archimedes, the Center of Gravity, and the First Law of Mechanics deals with the most fundamental aspects of physics. The book describes the main events in the life of Archimedes and the content of his works. It goes on to discuss a large number of experiments relating to the equilibrium of suspended bodies under the influence of Earth's gravitational force. All experiments are clearly described and performed with simple, inexpensive materials. These experiments lead to a clear conceptual definition of the center of gravity of material bodies and illustrate practical procedures for locating it precisely. The conditions of stable, neutral, and unstable equilibrium are analyzed. Many equilibrium toys and games are described and explained. Historical aspects of the concept are presented, together with the theoretical values of center of gravity obtained by Archimedes. The book also explains how to build and calibrate precise balances and levers. Several experiments are performed leading to a mathematical definition of the center of gravity and the first law of mechanics, also called the law of the lever. Consequences of this law and different explanations of it are described at the end of the book, together with an exhaustive analysis of the works of Euclid and Archimedes

The electric force of a current : Weber and the surface charges of resistive conductors carrying steady currents by André Koch Torres Assis( )

8 editions published in 2007 in English and German and held by 799 WorldCat member libraries worldwide

&Quot;The Electric Force of a Current analyzes the electric force between a charge and a circuit carrying a steady current when they are at rest relative to one another. It presents experiments and analytical calculations showing the existence of this force, contrary to the statements of many scientists. It also includes calculations of the potential and electric field inside and outside resistive conductors carrying steady currents, and the distribution of charges along the surface of the conductors that generate this field. It contains two appendices that discuss the works of Wilhelm Weber and Gustav Kirchhoff, and a substantial bibliography of modern literature on the topic."--BOOK JACKET

Weber's electrodynamics by André Koch Torres Assis( Book )

12 editions published between 1994 and 2011 in English and held by 212 WorldCat member libraries worldwide

This volume is a substantially complete presentation of the electrodynamics developed by Wilhelm Weber. Weber's force between point charges is explored and thoroughly analysed. Ampère's force between current elements is discussed in connection with modern experiments relating to the Ampère versus Grassmann--Biot--Savart controversy. Ampère's force is a central feature of this work, as Maxwell maintained it should always be in the study of electrodynamics, although it is included in few textbooks on electromagnetism. A detailed study of this force is an outstanding feature of this book. Other topical questions of physics are analysed, such as a potential-dependent inertial mass, Mach's principle and the origin of inertia, action at a distance as opposed to contact actions, etc. No previous knowledge of the subject is required, and all topics are introduced with both their historical backgrounds as well as modern experimental evidence. This volume will appeal to physicists, mathematicians, electrical and electronic engineers, historians and philosophers of science
