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 Myths of the Civil War written by Scott Hippensteel and published by Rowman & Littlefield. This book was released on 2021-11-15 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the spirit of Robert Adair’s cult classic The Physics of Baseball, here is a book that tackles the long-cherished myths of Civil War history—and ultimately shatters them, based on physics and mathematics. At what range was a Civil War sniper lethal? Did bullets ever “rain like hail”? Could one ever step across a battlefield by stepping only on bodies and never hard ground? How effective were Civil War muskets and rifles? How accurate are photographs and paintings? In this genre-bending work of history, Scott Hippensteel puts the tropes of Civil War history under the microscope and says, “Wait a minute!” Combining science and history, Hippensteel reexamines much that we hold dear about the Civil War and convincingly argues that memoirs and histories have gotten it wrong. This is a work of history and science for our era of “fake news”—and for well beyond. Readers will never look at the Civil War the same way again.

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.

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.
Download or read book Setting Aside All Authority written by Christopher M. Graney and published by University of Notre Dame Pess. This book was released on 2015-04-15 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Setting Aside All Authority is an important account and analysis of seventeenth-century scientific arguments against the Copernican system. Christopher M. Graney challenges the long-standing ideas that opponents of the heliocentric ideas of Copernicus and Galileo were primarily motivated by religion or devotion to an outdated intellectual tradition, and that they were in continual retreat in the face of telescopic discoveries. Graney calls on newly translated works by anti-Copernican writers of the time to demonstrate that science, not religion, played an important, and arguably predominant, role in the opposition to the Copernican system. Anti-Copernicans, building on the work of the Danish astronomer Tycho Brahe, were in fact able to build an increasingly strong scientific case against the heliocentric system at least through the middle of the seventeenth century, several decades after the advent of the telescope. The scientific case reached its apogee, Graney argues, in the 1651 New Almagest of the Italian Jesuit astronomer Giovanni Battista Riccioli, who used detailed telescopic observations of stars to construct a powerful scientific argument against Copernicus. Setting Aside All Authority includes the first English translation of Monsignor Francesco Ingoli’s essay to Galileo (disputing the Copernican system on the eve of the Inquisition’s condemnation of it in 1616) and excerpts from Riccioli's reports regarding his experiments with falling bodies.

Download or read book Cultures of Prediction written by Ann Johnson and published by MIT Press. This book was released on 2024-05-07 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: A probing examination of the dynamic history of predictive methods and values in science and engineering that helps us better understand today’s cultures of prediction. The ability to make reliable predictions based on robust and replicable methods is a defining feature of the scientific endeavor, allowing engineers to determine whether a building will stand up or where a cannonball will strike. Cultures of Prediction, which bridges history and philosophy, uncovers the dynamic history of prediction in science and engineering over four centuries. Ann Johnson and Johannes Lenhard identify four different cultures, or modes, of prediction in the history of science and engineering: rational, empirical, iterative-numerical, and exploratory-iterative. They show how all four develop together and interact with one another while emphasizing that mathematization is not a single unitary process but one that has taken many forms. The story is not one of the triumph of abstract mathematics or technology but of how different modes of prediction, complementary concepts of mathematization, and technology coevolved, building what the authors call “cultures of prediction.” The first part of the book examines prediction from early modernity up to the computer age. The second part probes computer-related cultures of prediction, which focus on making things and testing their performance, often in computer simulations. This new orientation challenges basic tenets of the philosophy of science, in which scientific theories and models are predominantly seen as explanatory rather than predictive. It also influences the types of research projects that scientists and engineers undertake, as well as which ones receive support from funding agencies.
