Atomic Bomb 5

Atomic Bomb 5 Essay On the morning of August 6, 1945, the first Atomic Bomb in history was dropped on the Japanese city of Hiroshima. Three days later, a second bomb was dropped on Nagasaki. Soon after, on August 14, 1945, the Japanese abruptly surrendered, abandoning their ancient customs regarding honor in war. The fact that only two bombs were able to bring an entire country to its knees is a true testament to the awesome power they held. There is nothing in modern warfare that can compete with the devastating effects of nuclear weapons. At the beginning of World War II, the Japanese were a major threat to the Asian World. On December 7, 1941, when they decided to attack Pearl Harbor (a US naval base in Hawaii), it was evident that their intentions were not limited to Asia. The United States entered World War II as a result of this attack. The war continued for six long years, and involved most of the major World Powers. During this time, there were many battles between the United States and Japan, i ncluding one of the bloodiest battles of World War II, which took place at Okinawa. If allowed to expand, Japan posed a serious threat to the allies. During the war, one of the most brilliant scientists in history, Albert Einstein, hypothesized that if the true power of the atom were released in a weapon, the results would be devastating. This was soon confirmed by a large portion of the scientific community. Whoever possessed such a weapon would be in complete power. Many government officials felt that such a weapon could put an end to the war. For this reason, in 1942, the United States decided to pursue the atomic bomb. Later that year, Franklin D. Roosevelt began the Manhattan Project. The Manhattan Project was a massive engineering enterprise aimed at the ultimate goal of creating an atomic bomb. At one time it employed over 129,000 workers. The United States was the only nation in the world with the capacity to work on such a high level. Though it cost approximately $2 billion dollars, many officials who knew about the Top Secret project felt it was well worth it- if the Atomic Bomb proved useful. Another major expense of the United States government was the development of the B-29, a bomber plane specifically designed for dropping Atomic Bombs. The estimated cost of this project is $3 billion dollars, bringing the total cost of the new atomic weapon to $5 billion dollars (approx. $50 billion 1998 dollars). If the Atomic Bomb failed, not only would many people lose their jobs, but the outcome of the war might have changed. For this reason, the Manhattan Project employed many of the top scientific minds of the world. Unbeknownst to the Allies, the Germans decided not to pursue an atomic weapon. They felt it was more important to spend the money on troops and machinery, and thought that they would have won the war before they were able to obtain an atomic weapon. They were also unaware of the top-secret Manhattan Project. The Japanese conducted small research on the possibility of building a bomb, but never fully pursued it. If the Germans had decided to build a bomb, and obtained it before the United States, they most certainly would have used it against the Allies. This is why it was so crucial for the U.S. to complete the Manhattan Project as quickly as possible. A German victory would have resulted in a history that is completely different from that which took place. If the Axis Powers had developed the Atomic Bomb, they would have been unstoppable. A nuclear weapon harnesses the power of the atom with a process known as an Uncontrollable Fission Reaction. In this process, a neutron (a subatomic particle found in the nucleus of atoms) is bombarded with the nucleus of a radioactive atom, such as Uranium or Plutonium. This causes the nucleus of the radioactive atom to become unstable, and split into two new atoms. To stabilize the new atoms, more neutrons are released, which move on to bombard with another radioactive nucleus.

History of Pennsylvania - Essay Example Prior to the entry of the Europeans into the new territories, the state was home to indigenous Indian tribes of Algonquian and Iroquoian linguistic origins like the Delawares, Shawnees, Susquehannocks, Eries and other unidentified tribes.2 During 1638-1655, it was the The Swedes who made settlements in Wilmington, Delaware area. The Dutch followed when they seized from the Swedes important trading posts in 1655. In 1664, the English assumed authority over the area gaining much control of the Delaware region in the name of the Duke of York.3 In the ensuing sections of the paper, the relevant periods in Pennsylvanian history would be discussed. The discourse will also focus on the founding of the State and how it shaped the future Pennsylvania. Pennsylvania, as mentioned earlier was the site of a major event in US history, the Declaration of Independence. In the months before the declaration, the state struggled with opponents to autonomy because gaining autonomy would mean the disruption of political and economic life as the Pennsylvanians knew and a death knell to the new State Constitution. Archeologists thought that the first inhabitants of the land that would later be known as Pennsylvania were inhabited by paleo-Indians who were nomadic and hunter-gatherers, and preferred to live in groups of twenty to thirty.4 Archeological evidences indicated that the early inhabitant used stone impediments. The Meadowcroft Rockshelter archeological site in Pennsylvania revealed that there were inhabitants in the area as early as 16,000 years ago.5 Before the first Europeans set foot on Pennsylvania, the Lenni Lenape or Delawares lived in the northern and southern parts of the Delaware Valley.6 On the west, the northern Susquehanna Valley was home to Iroquoian-speaking tribes.7 The Susquehannocks, on the other hand occupied the Lancaster Valley and conducted trade along the Great Minguas Path.8 By the time the Europeans arrived,

The Concept of Literacy to Prospective Teachers Essay

The Concept of Literacy to Prospective Teachers - Essay Example This begins with children who come into the classroom from different backgrounds, learning methods and special needs that should be enhanced. Each of these requires different formats for teaching literacy while helping children with their specific characteristics that are within the classroom. By developing this, there is the ability to create deeper understanding and knowledge that is a part of the education of children while enhancing learning abilities by meeting children with the culture which they understand. The development that is created from this becomes easier while allowing all students from diverse backgrounds to have their needs met with literacy (Flint, 2007). The second point which would be made would expand on the idea of reaching cultures into developing and working with specific tools for students. Language development is one that is based on creating skills and working with children to develop these with the use of scenarios and circumstances. Both oral and reading skills are developed specifically by helping to create the right learning environment so the skills are continuously practised and developed in a way that ensures all children are able to develop the right approach to reading and writing. This means that the environment in the classroom needs to be established in a manner that allows children to understand and develop their literacy skills over time and with continued support from the environment and teaching that is available. Using this as a foundation invites in cultural diversity and enhances the needs each child has (Flint, 2007). The third relevant point that would be used with teachers would be from the different ways in which children can be introduced to practising skills while boosting the diversity of the classroom.
