Electricity, Magnetism, And Light Saslow

This book provides a chronological introduction to the electromagnetic theory of light, using selected extracts from classic texts such as Gilbert’s De Magnete, Franklin’s Experiments and Observations on Electricity, and Huygens’ Treatise on Light. Particular attention is given to the works of Faraday, Maxwell and Heaviside, scientists who unified the formerly separate disciplines of electricity, magnetism and light. Their electromagnetic theory—developed during the 19th century—would lead to the invention of modern radar, electrical power grids, and telecommunication networks.

This textbook emphasizes connections between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigour inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result.

Knowledge of and skill in physics are essential foundations for studies in science and engineering. This book offers students an introduction to the basic concepts and principles of physics. It covers various topics specifically related to waves, sound, electricity, magnetism, and optics. Each chapter begins with a summary of concepts, principles, definitions, and formulae to be discussed, as well as ending with problems and solutions that illustrate the specific topic. Steps are detailed to help build reasoning and understanding. There are 250 worked problems and 100 exercises in the book, as well as 280 figures to help the reader visualize the processes being addressed. Computer calculations and solutions are carried out using wxMaxima to give insight and help build computational skills. The book is aimed at first-year undergraduate students studying introductory physics, and would also be useful for physics teachers in their instruction, particularly the exercises at the end of each chapter.

Over the course of 9 video lessons and many painting demonstrations, award-winning fine artist and plein air painter, John Burton, will share with you his extensive knowledge and expertise gained through decades of traveling and plein air painting in amazing scenarios and locales around the world. John meticulously crafted these lessons to be as helpful to a seasoned veteran as to someone who is just getting their feet wet. He will guide you on this journey, helping you to improve your painting, drawing, and observational skills through an elevated understanding of rhythm, gesture, and silhouetted shape.
