Most amateur astronomers – and many of those with similar interests but who are not currently practising observers – have only a sketchy understanding of space flight. This book provides an introduction to its mechanics. The beauty of this book, written by an engineer who is also an accomplished science writer, is that it covers the subject comprehensively, and yet is almost entirely descriptive and non-mathematical. It deals with all aspects of space flight, from how to leave the Earth (including the design of the rocket, mission planning, navigation and communication), to life in space and the effects of weightlessness. The book also includes sections describing how an amateur can track satellites and understand their orbital parameters.
ENOTENPLATO: Military tactics answer the questions of how best to deploy and employ forces on a small scale. Some practices have not changed since the dawn of warfare: assault, ambushes, skirmishing, turning flanks, reconnaissance, creating and using obstacles and defenses, etc. Using ground to best advantage has not changed much either. Heights, rivers, swamps, passes, choke points, and natural cover, can all be used in multiple ways. Before the nineteenth century, many military tactics were confined to battlefield concerns: how to maneuver units during combat in open terrain. Nowadays, specialized tactics exist for many situations, for example for securing a room in a building.
There are many myths and legends surrounding the advanced German aeronautical technology of the Second World War. There are also facts and proven events. Yet within these stories and behind these facts lie conspiracy theories, mistaken assumptions and denials that seem to contradict the evidence. So what really happened? How far ahead were the German scientists? And, of even greater interest, why and how?There have been other books about advanced German wartime aeronautics, yet few authors have fully examined the detail of the designs and their relevance to the fighter and bomber legends of the 1950s and '60s, let alone the current crop of military and civil all-wing or blended-wing aircraft. This book charts the story from it origins, through current-day innovations and beyond, into the all-wing future of tomorrow.
This book offers a comprehensive study and account of the co-evolution of technological and scientific literature in the early modern period (1450-1750). It examines the various relationships of these literatures in six areas of knowledge – Architecture, Chemistry, Gunnery, Mechanical Engineering, Mining, and Practical Mathematics – which represent the main types of advanced technological and scientific knowledge of the era. These six fields of technologically advanced knowledge and their interrelations and interactions with learned knowledge are investigated and discussed through a specific lens: by focusing on the technological literature. Among present-day historians of science, it ha...
This book takes readers back and forth through time and makes the past accessible to all families, students and the general reader and is an unprecedented collection of a list of events in chronological order and a wealth of informative knowledge about the rise and fall of empires, major scientific breakthroughs, groundbreaking inventions, and monumental moments about everything that has ever happened.
Poland has a long tradition of space-related research and activities, going back to the 15th-century astronomer Nicolaus Copernicus. In the 21st century, the Polish space sector is building stable cooperation between science and industry, developing innovative technologies, and stimulating contacts and foreign cooperation, despite the government only devoting around 0.01 percent of Poland’s GDP to its space sector. This overview of the Polish space sector covers the heritage of space-related activities in Poland, present-day development of space law in Poland, and a review of present applications and regulations in both commercial and public applications.
This book introduces readers to the topical area of CSI: critical space infrastructure, which is defined as an emerging domain of systems-of-systems encompassing hardware, workforce, environment, facilities, business and organizational entities. Further, it includes unmanned air systems, satellites, rockets, space probes, and orbital stations, and involves multi-directional interactions essential for maintenance of vital societal functions (i.e., health, safety, economic and social well-being), the loss or disruption of which would have significant impact on virtually any nation. The topics covered include the main elements of CSI, CSI taxonomy, effects of CSI on other infrastructure systems...
This volume offers a unique glimpse into a European household in 18th century India. Claude Martin was an entrepreneurial Frenchman who settled in Lucknow, capital of the rich Muslim state of Awadh (Oudh). The book presents the inventory of his houses here for the first time, together with the catalogue of books from his library. It gathers together six experts to examine Martin’s numerous possessions, and discuss his paintings, silverware, jewellery, textiles, weapons, carriages, boats and hot air balloons. His collection of scientific items imported from the best European instrument makers reveals his practical experiments with electricity and astronomy, while his buildings exploited hydraulic engineering to keep them cool. This book will appeal to readers fascinated by the introduction of Enlightenment ideas into post-Mughal India and the rise of a ‘common soldier’ to the highest ranks of the East India Company. Childless himself, Martin left money to found La Martinière schools in India and France.
