Download or read book Their Arrows Will Darken the Sun written by Mark Denny and published by JHU Press. This book was released on 2011-04-29 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The science of ballistics has a long history and starts with one question: How does a projectile move through the air? Even before physicists worked that one out, military engineers had been tinkering with ballistic devices for centuries. The trebuchet of the Middle Ages has given way to rocket power, and the science of ballistics has evolved to match the technology. Mark Denny’s survey covers this dynamic subject from prehistory to the weapons of tomorrow. Taking the bang-whiz-thud approach, Denny first talks about internal ballistics—Bang!—from before gunpowder to the development of modern firearms. External ballistics—Whiz!—are next, with discussions about short- and long-range trajectories. Denny’s lesson ends with a Thud!—an explanation of terminal ballistics. Throughout, Denny conveys applicable physics principles in a way that will appeal to technology buffs and ballistics enthusiasts alike. His fun and factual explanations are free of complicated equations; notes cover the key aspects of ballistics physics for the more technically inclined. Denny has perfected this engaging balance of science and story. For study or hobby, Their Arrows Will Darken the Sun is an entertaining guide to the world of ballistics.

Download or read book The Medieval Crossbow written by Stuart Ellis-Gorman and published by Pen and Sword Military. This book was released on 2022-07-20 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: An in-depth, illustrated history and technical study of this iconic weapon of the Middle Ages. The crossbow is an iconic weapon of the Middle Ages and, alongside the longbow, one of the most effective ranged weapons of the pre-gunpowder era. Unfortunately, despite its general fame it has been decades since an in-depth history of the medieval crossbow has been published, which is why Stuart Ellis-Gorman’s detailed, accessible, and highly illustrated study is so valuable. The Medieval Crossbow approaches the history of the crossbow from two directions. The first is a technical study of the design and construction of the medieval crossbow, the many different kinds of crossbows used during the Middle Ages, and finally a consideration of the relationship between crossbows and art. The second half of the book explores the history of the crossbow, from its origins in ancient China to its decline in sixteenth-century Europe. Along the way it explores the challenges in deciphering the crossbow’s early medieval history as well as its prominence in warfare and sport shooting in the High and Later Middle Ages. This fascinating book brings together the work of a wide range of accomplished crossbow scholars and incorporates the author’s own original research to create an account of the medieval crossbow that will appeal to anyone looking to gain an insight into one of the most important weapons of the Middle Ages.

Download or read book Rocket Science written by Mark Denny and published by Springer Nature. This book was released on 2019-10-08 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book about rocket science: what it is and what it does. From the earliest fireworks to nuclear-powered spacecraft, all you would ever want or need to know about the subject is here, along with a straightforward explanation of how, why and when things work—or sometimes don't. We begin with the history and workings of early terrestrial rocketry before moving onto the main subject of the book: how we get things into space and, on occasion, back again. Entirely math-free, the chapters weave together innumerable anecdotes, real-world examples, and easy walk-throughs to help readers break down the complex physics behind some of humankind’s most amazing feats. Neither a pure textbook nor a populist space travel tome, the book will educate, inform and above all entertain anyone intrigued by rocket science.

Download or read book The Gunpowder Age written by Tonio Andrade and published by Princeton University Press. This book was released on 2017-08-29 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: A first look at gunpowder's revolutionary impact on China's role in global history The Chinese invented gunpowder and began exploring its military uses as early as the 900s, four centuries before the technology passed to the West. But by the early 1800s, China had fallen so far behind the West in gunpowder warfare that it was easily defeated by Britain in the Opium War of 1839–42. What happened? In The Gunpowder Age, Tonio Andrade offers a compelling new answer, opening a fresh perspective on a key question of world history: why did the countries of western Europe surge to global importance starting in the 1500s while China slipped behind? Historians have long argued that gunpowder weapons helped Europeans establish global hegemony. Yet the inhabitants of what is today China not only invented guns and bombs but also, as Andrade shows, continued to innovate in gunpowder technology through the early 1700s—much longer than previously thought. Why, then, did China become so vulnerable? Andrade argues that one significant reason is that it was out of practice fighting wars, having enjoyed nearly a century of relative peace, since 1760. Indeed, he demonstrates that China—like Europe—was a powerful military innovator, particularly during times of great warfare, such as the violent century starting after the Opium War, when the Chinese once again quickly modernized their forces. Today, China is simply returning to its old position as one of the world's great military powers. By showing that China’s military dynamism was deeper, longer lasting, and more quickly recovered than previously understood, The Gunpowder Age challenges long-standing explanations of the so-called Great Divergence between the West and Asia.
