Electromagnetic theory is one of the fundamental pillars of physics, providing the framework for understanding electric and magnetic fields and their interactions. It is essential not only for classical physics but also for modern advancements in engineering, communications, and quantum mechanics. This chapter introduces the historical development of electrodynamics and the significance of Maxwell’s equations, which form the foundation of classical electromagnetism. The origins of electromagnetic theory can be traced back to early observations of static electricity and magnetism. The ancient Greeks, particularly Thales of Miletus, noted that rubbing amber could attract small objects, laying the groundwork for electrostatics. By the 17th century, William Gilbert’s studies on magnetism and Benjamin Franklin’s experiments on electricity further developed the understanding of electric and magnetic phenomena. The 18th and 19th centuries saw rapid progress, with Charles-Augustin de Coulomb formulating the inverse-square law of electrostatics and André-Marie Ampère discovering the relationship between current and magnetic fields. Michael Faraday’s groundbreaking work on electromagnetic induction demonstrated that a changing magnetic field could induce an electric current, setting the stage for the unification of electricity and magnetism.Ver livro

This book explains the properties for each type of spring, plus essential materials and methods. Few mechanical devices are entirely devoid of springs of one sort or another, but satisfactory operation rests on details such as spring strength and degree of movement. Yet information on calculating and making springs is not easily available. Designing springs can be difficult due to the number of variables and the complexity of the formula. The book also introduces the designer to charts and nomograms, which greatly simplify the process. Topics include tension and compression spring principles, compression and spring design, examples for winding coil springs, how to design, make, and coil a leaf spring, torsion spring, and I.C. engine valve springs.Ver livro
A "quirky, endlessly entertaining" look at the surprising history of the pigeon (Simon Winchester). Domesticated since the dawn of man, pigeons have been used as crucial communicators in war by every major historical superpower from ancient Egypt to the United States and are credited with saving thousands of lives. They have been worshipped as fertility goddesses and revered as symbols of peace. Charles Darwin relied heavily on pigeons to help formulate and support his theory of evolution. Yet today they are reviled as "rats with wings." To research this lively history of the humble pigeon, the author traveled across the United States and Europe to meet with pigeon fanciers and pigeon haters in a quest to find out how we came to misunderstand one of mankind’s most helpful and steadfast companions. Pigeons captures a Brooklyn man's quest to win the Main Event (the pigeon world's equivalent of the Kentucky Derby), as well as a convention dedicated to breeding the perfect bird. The author participates in a live pigeon shoot where entrants pay $150; he tracks down Mike Tyson, the nation's most famous pigeon lover; he spends time with Queen Elizabeth's Royal Pigeon Handler; and he sheds light on a radical "pro-pigeon underground" in New York City. In Pigeons, Andrew D. Blechman reveals for the first time the remarkable story behind this seemingly unremarkable bird.Ver livro
