The Enigma was a German ciphering machine used in World War II. In the later years of the war, one was stolen and the Allies were able to decipher German messages, helping the Allies to resist and come to victory. It is said that if the Allies had not broken the Enigma, the war could have gone on for one or two years longer than it did, making it a very important part of the story of World War II. The Mechanics of the Enigma Before 1919, four different men, from four different countries, created very similar ciphering machines all using a rotor or wired code wheel. Edward H. Hebern, United States; Arthur Scherbius, Germany; Hugo Alexander Koch, Netherlands; and Arvid Gerhard Damm, Sweden. Three of the four inventors were unable to complete their machines due to lack of funds. Only Scherbius, an electrical engineer from Germany, was able to complete his ciphering machine. He named the successful creation The Enigma. Scherbius’s first model was big, bulky, and had a keyboard from a typewriter to input code. Four geared wheels drove four rotors. The four wheels drove one rotor ea...
The sender would type the message in plaintext (not encrypted) and the letters would be illuminated on a glass screen. With the press of each typewriter key the rotor would shift 1/26 of a revolution giving each letter a different encryption each time, which made the code so difficult to crack. Due to the complexity of the code the enigma became very useful for the Germans for radioing messages to u-boats. The cipher was finally broken when the British were able to capture some key documents from a German warship.
European states started embarking on a sequence of worldwide explorations that marked a new period in the world during the start of the 15th century. This period was called the Age of Exploration and it extended to the early 17th century, allowing Western Europe to venture to places like Africa, America and the Far East. This period is defined by figures like Ferdinand Magellan, the first to go crosswise the Atlantic to the Pacific Ocean as well as the first to go around the globe.
In the fall of 1931, the Atlantic Ocean was the boiling point of a criminal battle between the British and Germans. Most people think that the Battle of the Atlantic may have decided World War II’s outcome. This battle was the dominating factor throughout the war. The Battle of the Atlantic was a violent and destructive battle. Many people lost their lives fighting in this battle. New technology was one of the major factors in the Allies winning the long and crucial Battle of the Atlantic.
Further, Daughan covers the British blockade on American ports and the Napoleonic Wars. First, the British blockade on 1813 made difficult for American flagships to leave ports because the British Navy blocked almost all American ports with the exception of New England which provided goods to the British Navy during the war. Secondly, Daughan adds that the Napoleonic wars had a major impact on the American local war; exclusively, Napoleon’s defeat in Russia gave more confidence to Britain for supporting the War of 1812 longer. In contrast, A.J. Langguth did not include in his book, Union 1812: The Americans Who Fought the Second War of Independence, any international aspect that might influence the War of 1812.
In The Landscape of History, John Lewis Gaddis makes a cohesive argument concerning about the debate over the objectivity of truth by stating “objectivity as a consequence is hardly possible, and that there is, therefore, no such thing as truth (Gaddis 29). The question for objective history has long been debated by numerous historians, and the differing viewpoints of history have led to a transition in our ways of thinking in the modern world. Ultimately, the question that this paper focuses on is: to what extent is history objective? Along with this, the relation to historical consciousness and the challenges of living in modernity will also be assessed. This paper will analyze the texts of John Lewis Gaddis, Nietzsche and the Birth of Tragedy, Modernity and Historical Vision, Living in Modernity, and Hermeneutics. Finally, the paper will argue that history is not largely objective, and is fundamentally shaped through the historian’s subjectivity.
Elected in 1932 following the Great Depression, Franklin Delano Roosevelt took on his presidency as a challenge to reform the United States by finding ways to provide a larger amount of people economic security in an unequal financial environment. To accomplish this goal, Roosevelt not only implemented a variety of New Deal programs under the categories of reform, recovery and relief, but also redefined what the word “liberty” meant for Americans.
The Aztec Empire was the largest civilization of the Americas in the early 16th century until Spanish conquistadors arrived in the New World. A motley crew of men from Spain, they were led by Hernan Cortes who intended to expand lands for the Spanish monarch and through many factors he was able to do just that. The three main factors that contributed to the fall of Tenochtitlan by the hands of Spanish conquistadors were significance of native allies, difference in battle tactics among the natives and conquistadors, and widespread disease. Another chapter in the Spanish colonization of the Americas, this one stands out in particular due to its unorthodox sequence of events that led a small group of men to defeating an entire empire in a few short years.
God began His greatest work of creation. When God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground"(Genesis 1:26).
Mark I. It was actually a electromechanical calculation. It is said that this was the first potentially computers. In 1951 Remington Rand’s came out with the UNIVAC it began
In 1930 they had found the source of their problem. Germany had hired, “Hans Schmidt, who invented the enigma machine”, (Sales). This machine enabled Germany to send messages effortlessly with the security of knowing the codes could not be broken. Initially there was only one machine that was to be used as a public machine, but soon the German military contracted Schmidt to build a machine that the German Military could only use.
Throughout the course of Africa’s history, imperialism is one of the biggest transformations that could have happened. More specifically, South Africa. Though it happened almost one hundred and eighty years ago, we are still capable of seeing the different impacts it had on modern South Africa. You should care about the effects of imperialism because you can still see the different effects imperialism has had on South Africa. But, did imperialism have a positive or negative impact on modern South Africa? I believe that though imperialism has had some positive impacts, most of the outcomes were negative. I believe this for several reasons.
The trends that have been most instrumental in the shaping of America over the past sixty years have been suburbanization and the development of our consumer culture. These two phenomena have changed not only the face of America, but also the fabric of our society, our values and aspirations. Suburbanization and consumer culture are broad, sweeping terms that encompass many different catalysts of change. However, the automobile is an important product and tool of both of these institutions. This paper examines the inundation of American society by the automobile during the post war era as a key catalyst for the rise of consumer culture, its role in facilitating suburbanization and some of the negative impacts the automobile has had on America. Over the past sixty years America has changed greatly to become what it is today, and these changes have largely been driven by our national love affair with the automobile.
Herman Hollerith (1860 - 1929) founded IBM ( as the Tabulating Machine Company ) in 1896. The company renames known as IBM in 1924. In 1906 Lee D. Forest in America developed the electronic tube (an electronic value). Before this it would have been impossible to make digital electronic computers. In 1919 W. H. Eccles and F. W. Jordan published the first flip-flop circuit design.
