What do a bumble bee and a 747 jet have in common? It’s not a trick question. The fact is they have quite a lot in common. They both have wings. They both fly. And they’re both ideally suited to it. They just do it differently. Why Don’t Jumbo Jets Flap Their Wings? offers a fascinating explanation of how nature and human engineers each arrived at powered flight. What emerges is a highly readable account of two very different approaches to solving the same fundamental problems of moving through the air, including lift, thrust, turning, and landing. The book traces the slow and deliberate evolutionary process of animal flight—in birds, bats, and insects—over millions of years and compares it to the directed efforts of human beings to create the aircraft over the course of a single century. Among the many questions the book answers: Why are wings necessary for flight? How do different wings fly differently? When did flight evolve in animals? What vision, knowledge, and technology was needed before humans could learn to fly? Why are animals and aircrafts perfectly suited to the kind of flying they do? David E. Alexander first describes the basic properties of wings before launching into the diverse challenges of flight and the concepts of flight aerodynamics and control to present an integrated view that shows both why birds have historically had little influence on aeronautical engineering and exciting new areas of technology where engineers are successfully borrowing ideas from animals.

""Aviation Technology"" explores the fascinating world of human flight, delving into the scientific principles and technological innovations that have made aviation possible. The book focuses on three key areas: aerodynamics, propulsion systems, and aircraft structures, providing readers with a comprehensive understanding of how aircraft generate lift, propel themselves through the air, and maintain structural integrity under extreme conditions. From the Wright brothers' first powered flight to modern jet engines and emerging electric propulsion technologies, the book traces the rapid advancements in aviation technology over the past century. It presents complex concepts in an accessible manner, using clear language, analogies, and illustrations to explain the delicate balance of forces that enable sustained, controlled flight. The book's unique approach combines technical explanations with real-world applications and future projections, making it valuable for engineering students, aviation professionals, and technology enthusiasts alike. As readers progress through the chapters, they'll gain insights into aircraft design, flight planning, and aviation safety, while also exploring emerging technologies like hypersonic flight and electric vertical takeoff and landing vehicles. By addressing ongoing debates in the field, such as the future of supersonic commercial flight and the potential for electric aircraft to reduce aviation's carbon footprint, ""Aviation Technology"" encourages critical thinking about the future of air travel and inspires curiosity about one of humanity's greatest achievements.

The Eastern Professional Basketball League (1946-78) was fast and physical, often played in tiny, smoke-filled gyms across the northeast and featuring the best players who just couldn’t make the NBA—many because of unofficial quotas on Black players, some because of scandals, and others because they weren’t quite good enough in the years when the NBA had less than 100 players. In Boxed out of the NBA: Remembering the Eastern Professional Basketball League, Syl Sobel and Jay Rosenstein tell the fascinating story of a league that was a pro basketball institution for over 30 years, showcasing top players from around the country. During the early years of professional basketball, the Eastern League was the next-best professional league in the world after the NBA. It was home to big-name players such as Sherman White, Jack Molinas, and Bill Spivey, who were implicated in college gambling scandals in the 1950s and were barred from the NBA, and top Black players such as Hal “King” Lear, Julius McCoy, and Wally Choice, who could not make the NBA into the early 1960s due to unwritten team quotas on African-American players. Featuring interviews with some 40 former Eastern League coaches, referees, fans, and players—including Syracuse University coach Jim Boeheim, former Temple University coach John Chaney, former Detroit Pistons player and coach Ray Scott, former NBA coach and ESPN analyst Hubie Brown, and former NBA player and coach Bob Weiss—this book provides an intimate, first-hand account of small-town professional basketball at its best.
