Nikola Tesla Essay - 1590 Words

quot;Were we to seize and eliminate from our industrial world the results of Mr. Teslas work, the wheels of industry would cease to turn, our electric cars and trains would stop, our towns would be dark, our mills would be dead and idle. Yes, so far reaching is his work that it has become the warp and woof of industry... His name marks an epoch in the advance of electrical science. From that work has sprung a revolution...quot; -B.A. Behrend If you were to go to an encyclopedia and tried to find out who invented the radio, X- rays, and the tube amplifier, this is what you would find: radio was invented by Marconi, X- rays by Roentgen, and the tube amplifier by de Forest. While youre there, look to see who invented the fluorescent†¦show more content†¦Seeing that there were none, Tesla invented the predecessors to the motors used in every appliance in our houses. Inventing these motors was not simple, since scientists of the late 1800s were convinced that because no motor could be devised for an AC system, trying to develop a motor for it was waste of time. After all, AC current reverses direction 60 times a second, which would make the motor rock back and forth and never get anywhere. Tesla easily solved this problem and proved everyone wrong by developing a working motor for the AC system. In May 1885, word of the AC system was heard by George Westinghouse. Tesla signed contract with Westinghouse under which Tesla would receive $2.50 for each Kilowatt of AC electricity sold. Tesla finally had the money to conduct all the experiments he wanted. The problem was Edison. He had too much invested in his DC system of electricity. So Edison tried his best to discredit Tesla. He constantly tried to show that AC electricity was far more dangerous than DC electricity. Tesla easily countered this. At the 1893 World Exposition in Chicago, Tesla demonst rated how safe AC electricity was by passing high frequency AC electricity through his body to power light bulbs. He then shot lightning bolts from his Tesla Coils into the crowd, without harm. Tesla had dramatically proven once an for all that AC electricity was safe to use. In addition, Tesla also used Fluorescent bulbs in his lab about forty years before they wereShow MoreRelatedNikola Tesla Essay1550 Words   |  7 PagesNikola Tesla was born midnight on July 10, 1856, in Smiljan, Lika, which at that time was part of the Austrian-Hungarian Empire, which is now known as Croatia.

North And South By Elizabeth Cleghorn - 1128 Words

Welcome, welcome! Come one, come all to Aidan’s Amazing Writing Emporium! The reason for this piece is to compare and contrast fiction and nonfiction writings from a selected time period. The time period I chose was the Industrial Revolution. The Industrial Revolution was when societies went from making everything by hand to using machines and factories. It was a huge leap in human achievement and helped businesses make a lot more money than they used to, but also forced lower class people to work long hours in factories to produce goods. For the fiction writings, I chose the book North and South by Elizabeth Cleghorn and the short story â€Å"Life in the Industrial Revolution by someone with the online username of PukaMaseillaise. They†¦show more content†¦Thirdly is the setting of each writing. Life in the Industrial Revolution takes place in a poor town and dangerous factories, while North and South focuses on the life of a lower class girl who lives in a quiet to wn at first and then moves to the city but does not work in a factory. From LIR is this text quote: We were forced to move to the city and work in a factory, where we tend machines all day long until the day is over... In LIR, the narrator lives in a hut with many others and attends a factory six days a week with very long hours to work and earn money. Next is the fiction to nonfiction section. For my nonfiction books I chose The World for a Shilling: How the Great Exhibition of 1851 Shaped a Nation by Michael Leapman, The Most Powerful Idea in the World: A Story of Steam, Industry, and Invention by William Rosen, and The Victorian Internet: The Remarkable Story of the Telegraph and the Nineteenth Century s On-line Pioneers by Tom Standage. These books also compare and contrast in some ways. Firstly, the use of steam engines. LIR and Most Powerful Idea both include steam engines and how they worked in factories. (You’re going to be hearing the words â€Å"steam engine† a lot in this essay.) Second, are the â€Å"specifics† of the steam engine use. In LIR, the steam engine is used to run machines in factories where people tend to them to make money,

Navy Chief Petty Officer Medal of Honor Recipients Free Essays

The Chief Petty Officer is a rank in the U.S. Navy just above the rank of the Petty Officer First Class. We will write a custom essay sample on Navy Chief Petty Officer Medal of Honor Recipients or any similar topic only for you Order Now They serve both as leaders and technical experts.   Promotion as a Chief Petty Officer requires superior evaluation and time in service. The Navy Medal of Honor is America’s oldest and still continuing award. The Medal of Honor is the supreme award in the United States of America for bravery in wars.   Any member of the Armed Services of the United States who performs exceptionally in his field of warfare during martial operations risking his life to protect the interests of the country is awarded the Medal of Honor. Since everyone in the Armed Services has values of bravery and selflessness, the recommendation for this award is made with the greatest care and consideration. When the Medal was initially awarded during the Civil Wars, it was the only medal for bravery in wars; but during the Spanish American War, it became the highest honor, with many other medals being given for valor in wars. Apart from the respect the Medal entails, the recipients have many other privileges like increased monetary benefits, wearing their uniforms wherever they choose to, and attending Presidential inaugurations. Even the children of the recipients of the Medal of Honor enjoy privileges. If they are qualified and desire to attend the U.S. military academies, they can do so without any restrictions of quotas. So far, more that 3400 Medal of Honor awards have been given. Getting the prestigious Medal would be the proudest moment of any serviceman, and John Finn had  the taste of it when it was placed around his neck in recognition for his valor in the Second World War. Born in Los Angeles, California, on July 23, 1909, he enlisted in the Navy in 1926 and served as a Chief Petty Officer. John Finn was awarded the prestigious Medal of Honor for his conspicuous heroism and gallantry while at the Naval Air Station Kahoehe Bay, Hawaii, during the air raid by Japan, which targeted the facility.   With a machine gun, Chief Finn effectively fired at the enemy planes. Though he received severe wounds, he put up a brave fight and created great havoc to the enemy planes. His action during the attack was indeed amazing. George Brady was yet another proud possessor of the Medal of Honor. He was born on September 7, 1867.   He was a Chief Gunner’s Mate in the U.S. Navy.   George Brady was awarded the Medal of Honor for his exceptional performance in the Spanish American War. George Brady proved a real asset to the U.S. forces. He was on board the torpedo boat Winslow when enemy forces targeted it. The boat was extensively exposed to bombs and suffered great damage. He repaired the steering gear and promptly maintained watertight integrity and thus saved the vessel.   His masterly skills and untiring loyalty to duty was greatly appreciated, and he was awarded the Medal of Honor. Though every serviceman fights for the country risking his life, such events, which depict individual courage and bravery, are the grounds on which a recommendation for the Medal of Honor is made.   The worth of the Medal of Honor is so  great that senior officers and even the President salutes the Medal, thereby the recipient wearing it.

I Integrating Science and Mathematics free essay sample

One major concern when science and mathematic is being integrated is the way teachers will teach the two this is a continuing professional concern. Educators will have to make the efforts to direct the presentation of science and mathematics lessons In an era dominated by mathematics, science, and technology , it is essential that science and mathematics be taught in K-12 and that classroom teachers are equipped with the knowledge and skills to teach both science and mathematics meaningfully to students. However, in a test driven curriculum where students and teachers are evaluated on student performance based on reading and mathematics standardized test scores, teaching meaningful science remains a challenge (2007 Joseph M. Furner ). Because of the many benefits of integrations academic subjects this is not a new concept. The integrations of mathematic and science help students thinks about the â€Å"real world â€Å"and by doing so the NCTM standards are met. There are others benefit of the integrations of math and science it allows the students to start thinking about why things happen which in term will the students a more practical approach to learning and using mathematics with the application of science. A common question asked by students is’ are we ever going to use this when we leave school† the integration between math and science will show the students how usefulness and importance of mathematic which therefore enables them to develop new understandings and skills. Educators in all schools systems have struggled to rise students test scores one advantage that integrating math with science is to help students’ scores increate. In defining how to integrate math and science, White and Berlin (1992), and Sunal and Furner (1995) made the following recommendations: †¢Base integration on how students experience, organize, and think about science and †¢Take advantage of patterns as children from the day they are born are looking at patterns and trying to make sense of the world Collect and use data in problem-based integrated activities that invoke process skills. †¢Integrate where there is an overlapping content in math and science. †¢Be sensitive to what students believe and feel about math and science, their involvement and the confidence in their ability to do science and math. †¢ Use instructional strategies that would bridge the gap between students’ classroom experiences and real-life experiences outside th e classroom. When integrating math and science in the classroom it will encompasses a number of considerations, an example of this integrating would be if the teachers taught math entirety as a part of the science or to teach math as a language tool for teaching science, or teaching science entirely as a part of math. The teachers’ training and knowledge level will determine their confident level in teaching math and science and if the teacher lacks either this need to be addressed , for example if the teachers is confident in their able to teach math but not science some teacher may not know how to teach all require science disciplines. Beane (1995) defines curriculum integration as a way of thinking about the purpose of schools, the sources of curriculum, and the basis of knowledge. Beane believes in order to define curriculum integration; there must be a reference to knowledge. According to Jacobs (1989) and the Association for Supervision and Curriculum Development (1989), planning and teaching interdisciplinary lessons involve two or more teachers, common planning time, the same students, teachers skilled in professional collaboration, consensus building, and curriculum development. As Robinson (1994) pointed out, the following considerations are necessary for the preparation of interdisciplinary instruction. Some state tests are being designed to reflect an integrated curriculum. In Connecticut, students take the CAPT (Connecticut Academic Performance Test) while in high school. While traditional assessments determine what students know, the CAPT test was intended to determine what students can do with that knowledge. The objective of the test is for students to be able to apply what they have learned to other situations. Another reason to consider the integration of curriculum is because it is the way people learn. Current brain research points out that the human brain looks for patterns and interconnections as its way of making sense of things. Unfortunately, in many schools students learn one subject in one classroom and then move on to the next classroom for the next subject. By delivering the curriculum in this format, subjects lack coherence and therefore students become disconnected and disengaged. Educators presume that students will miraculously make the associations between subjects by themselves and will see how the subjects â€Å"fit† together and into the real world. With an integrated curriculum, teachers do not need to guess about whether the connections have been made by students, the connections will be clear. Integrating mathematics into the curriculum can be a challenge for many teachers. It takes a great amount of time and teamwork but the benefits outweigh any possible disadvantages. Integration of subjects gives meaningful contexts for students rather than having them learn in isolation. As a result, this relevance of information better prepares all students. Teaching mathematics in isolation does students a disservice. One goal of mathematics teachers is to produce a mathematically literate nation where people can use the concepts from this subject to solve real-life problems. When mathematics is connected with other subjects, students can develop the intellectual scaffolding they need that will aid them and the nation for the future. Mathematical assessments should be more than just tests at the end of every chapter. Assessments should inform and guide teachers and enhance student learning. They should give students the opportunity to communicate mathematically and apply their knowledge. PBAs do this by providing an open-ended curriculum and can more accurately assess the skills of a diverse group of students. PBAs are a way for students to use their expertise and knowledge to â€Å"tie everything together† because the goal of acquiring knowledge should be its application. Both mathematics and science education are highly influenced by standards developed by professional organizations. For math, the National Council of Teachers of mathematics [NCTM] (2000) produced Principles and Standards for School Mathematics. This document purports six principles for school mathematics and five curriculum and five process standards. Similarly, the National Research Council [NRC] (1996) produced National Science Education Standards that provides standards for science teaching, learning, and professional development.
