How Has Warfare Been Changed by Science and Technology?
Warfare is an element of the human experience since the beginning of time. While warfare is a destructive force, it also is a very creative force as many technologies have been developed as a result of the need to win a war. As new technologies developed so did warfare.
Simple Tools
The earliest implementation of scientific principles in warfare relate to the basic weapons that were produced. It has been hypothesized that rocks either thrown or used as a bludgeoning tool were the first weapons used by humans. As humans experimented with various warfare techniques they discovered how simple scientific tools could be used to improve their weapons. For example, the theory of the lever was used to create clubs and axes that could be used for a weapon.
Complex Tools
As humans experimented more with basic tools they learned how to create more complex tools. These complex tools were then used to develop more effective weapons. Projectiles, for example, that used complex tools and a basic understanding of aerodynamics led to the development of spears and sling shots. These allowed humans to attack an opponent from a distance. As their understanding of aerodynamics improved and their tool science improved more advanced projectile launchers were developed, including the bow and arrow and the compound bow.
Chemistry
The science of chemistry changed warfare the most for humans. It not only provided the ability for humans to create weapons that were strong, sharp and more malleable than stone and wooden weapons, but it also provided them with the ability to create more destructive weapons.
The first chemical advancement that humans made was the science of metallurgy. This science explored the methodology of extracting pure metals from metal ores. It also focused on how to create weapons from the metal that was extracted through molding, forming, hammering and sharpening the metal shapes. Copper was one of the first metals to be extracted and used as a material for weapons. Bronze was the first metal alloy to be created in 4000 B.C. The alloy was stronger and more durable than copper. Smelting iron was developed in 1250 B.C. by the Hittites who discovered that heating iron with charcoal create an extra strong veneer on the iron that was basically a layer of steel that was created by a chemical bonding of the carbon from the charcoal and the iron.
Explosives were the next chemical advancement to be discovered by humans. The Chinese had for centuries been using gunpowder to power their fireworks. However, in the 13th century a European weapons expert began to experiment with the compound and the weapon applications of this compound were developed.
Firearms
As a result of the development of gunpowder a wide range of firearms were developed. These weapons changed the face of warfare for ever. Battles were bloodier and more destructive than ever before as the firearms reduced the amount of skill needed to fight in a war, as well as provide a more power killing weapon.
In the 1500s hand held firearms were developed. By the 1600s the design of firearms had improved and long range projectiles were possible to launch using gunpowder and cannons. The first real improvement to the accuracy and reliability of a firearm came in 1836 when Samuel Colt invented the Colt Revolver. In 1903 the Ross Rifle was introduced. Then in 1947 the first automatic hand held firearm was developed, the AK-47. These weapons influenced both modern warfare and popular culture for generations to come.

The Changing Character of War $110 Over the last decade (and indeed ever since the Cold War), the rise of insurgents and non-state actors in war, and their readiness to use terror and other irregular methods of fighting, have led commentators to speak of 'new wars'. They have assumed that the 'old wars' were waged solely between states, and were accordingly fought between comparable and 'symmetrical' armed forces. Much of this commentary has lacked context or sophistication. It has been bounded by norms andtheories more than the messiness of reality. Fed by the impact of the 9/11 attacks, it has privileged some wars and certain trends over others. Most obviously it has been historically unaware. But it has also failed to consider many of the other dimensions which help us to define what war is - legal,ethical, religious, and social. The Changing Character of War, the fruit of a five-year interdisciplinary programme at Oxford of the same name, draws together all these themes, in order to distinguish between what is really changing about war and what only seems to be changing. Self-evidently, as the product of its own times, the character of each war is always changing. But if war's character is in flux, its underlying nature contains its own internal consistency. Each war is anadversarial business, capable of generating its own dynamic, and therefore of spiralling in directions that are never totally predictable. War is both utilitarian, the tool of policy, and dysfunctional. This book brings together scholars with world-wide reputations, drawn from a clutch of different disciplines,but united by a common intellectual goal: that of understanding a problem of extraordinary importance for our times.This book is a project of the Oxford Leverhulme Programme on the Changing Character of War. |

Changing of Knowledge in Composition $24 Lance Massey and Richard Gebhardt offer in this collection many signs that composition again faces a moment of precariousness, even as it did in the 1980s—the years of the great divorce from literary studies. The contours of writing in the university again are rapidly changing, making the objects of scholarship in composition again unstable. Composition is poised to move not from modern to postmodern but from process to postprocess, from a service-oriented "field" to a research-driven "discipline." Some would say we are already there. Momentum is building to replace "composition" and the pedagogical imperative long implied in that term with a "writing studies" model devoted to the study of composition as a fundamental tool of, and force within, all areas of human activity. Appropriately, contributors here use Stephen M. North's 1987 book The Making of Knowledge in Composition to frame and background their discussion, as they look at both the present state of the field and its potential futures. As in North's volume, The Changing of Knowledge in Composition describes a body of research and pedagogy brimming with conflicting claims, methodologies, and politics, and with little consensus regarding the proper subjects and modes of inquiry. The deep ambivalence within the field itself is evident in this collection. Contributors here envision composition both as retaining its commitment to broad-based, generalized writing instruction and as heading toward content-based vertical writing programs in departments and programs of writing studies. They both challenge and affirm composition's pedagogical heritage. And they sound both sanguine and pessimistic notes about composition's future. |

Understanding and Changing Your Management Style $43.24 What makes a good manager? Are the best managers born that way, while everyone else must struggle with the role and responsibilities? Robert Benfari`s answer in Understanding and Changing Your Management Style is that the way we manage is a mixture of conceptual skills and interpersonal factors that can be analyzed, understood, and changed. Starting with the powerful tool of the Myers-Briggs Type Indicator (the leading personality typology used in business today), Benfari identifies the most significant ingredients of effective management and shows readers how to devise strategies for improving their ability to resolve conflicts, solve problems, influence others, manage stress, and handle difficult situations and people at work. Understanding and Changing Your Management Style combines Benfari`s two previous books, Understanding Your Management Style and Changing Your Management Style, in one updated volume. |

Understanding Changing Telecommunications $150 The field of telecommunications is becoming ever more complex. In order to manage the new Telecom industry it is necessary not only to understand its 3 main components, namely the end users, the technology and networks, and the business aspects, but also their vital inter-relationships. Complexity leads to uncertainty, and one effect of uncertainty is for people to underestimate the complexity of the business and the technology. This book takes a holistic approach to the subject and can be used as a tool for decreasing this uncertainty.  During 2000 many operators paid extremely high sums of money for 3G licenses in a number of European countries, supposing a potential corresponding and balancing revenue from mobile services in the new frequency band. Obviously today the licenses are questionable. Consequently, suppliers and operators were forced to reduce their international work force.  What are the underlying reasons? Since the true rate and level of development was hardly foreseen by anyone, the picture is complex, including factors such as psychology and belief in a new economy. It is immediately clear that the end user impact has been severely under-estimated. It is also clear that the expected development has and is happening, with more speed than expected, and continues to be complemented with solutions such as wireless LANs. This book treats the paradigm shift from a number of angles: user needs and demands, deregulation of telecom and the convergence between telecommunications, data communications and the media industry, the service plan, service implementation, QoS, and Security. Understanding Changing Telecommunications focuses on the overall principles and context of the new telecommunications world rather than on high-level technical descriptions in order to aid the understanding and development of the next generation of telecom networks. e.g. multimedia over IP and 3G. Discusses the development of telecommunications up until 2005 Provides a holistic view of the world of telecommunications Covers three main areas: End-users, Technologies and Networks, and Telecom Business, and their vital inter-relationships Offers support and advice for those needing to implement business plans Essential reading for staff with operators and providers involved in the telecom networks, especially management, planning and design, development, integration and training, as well as Business analysts and investors keen to understand the current state of the Telecom industry. |
