Cause and Effect: The Outbreak of World War II

War , in the popular sense, a conflict between political groups involving hostilities of considerable duration and magnitude. In the usage of social science , certain qualifications are added. Sociologists usually apply the term to such conflicts only if they are initiated and conducted in accordance with socially recognized forms. They treat war as an institution recognized in custom or in law. Military writers usually confine the term to hostilities in which the contending groups are sufficiently equal in power to render the outcome uncertain for a time. Armed conflicts of powerful states with isolated and powerless peoples are usually called pacifications, military expeditions, or explorations; with small states, they are called interventions or reprisals; and with internal groups, rebellions or insurrections. In all ages war has been an important topic of analysis.

Pinpointing the causes of a vast, global event like the Second World War is a challenging task for the historian. Events—especially enormous, multifaceted events—have multiple causes and multiple inputs. A proximate cause is an incident that appears to directly trigger an event, as the election of Abraham Lincoln in November and the shelling of Fort Sumter led to the outbreak of the Civil War. In the case of the Civil War, for example, historians often point to the growing sectional polarization that divided the nation in the s and s, the national debate over the future of slavery, and the divergent economic paths that distinguished North and South during the antebellum period. In the case of the Second World War, historians generally point to a series of conditions that helped contribute to its outbreak. The unbalanced Treaty of Versailles which forced a crippling peace on Germany to end the First World War and the global depression that enveloped the world during the s which led to particularly desperate conditions in many European nations as well as the United States usually emerge as two of the most crucial.

The history of radar where radar stands for RA dio D etection A nd R anging started with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell 's seminal work on electromagnetism. Numerous similar systems, which provided directional information to objects over short ranges, were developed over the next two decades. The development of systems able to produce short pulses of radio energy was the key advance that allowed modern radar systems to come into existence. By timing the pulses on an oscilloscope , the range could be determined and the direction of the antenna revealed the angular location of the targets.

The Agency's collection, begun in Washington, DC, during World War II, moved in to Maxwell Air Force Base, the site of Air University, to provide research facilities for professional military education students, the faculty, visiting scholars, and the general public. It consists today of over 70,, pages devoted to the history of the service, and represents the world's largest and most valuable organized collection of documents on US military aviation. Monday-Friday a. Documents requested by the general public will be sent to them.

Но сообщать имена жертв… с точки зрения человека в очках в металлической оправе, это было признаком особой элегантности стиля. Его пальцы снова задвигались, приводя в действие сотовый модем, и перед глазами появилось: СООБЩЕНИЕ ОТПРАВЛЕНО ГЛАВА 26 Сидя на скамейке напротив городской больницы, Беккер думал о том, что делать. Звонки в агентства услуг сопровождения ничего не дали.

ГЛАВА 49 Беккер с трудом поднялся и рухнул на пустое сиденье. - Ну и полет, придурок, - издевательски хмыкнул парень с тремя косичками.
