Ethan Frome man of duty essays

Ethan Frome man of duty essays Ethan Frome is lead by desire however controlled by duty. Ethan is a self-contradicting character. Ethan is firm and strong, however Ethan is also feeble and weak. Ethan desires Mattie however he is bound to his duty as a husband and tradition to Zeena. Ethan is strong in that he sticks to his duty, but Ethan shows his weakness when he is manipulated by Zeena. I find the season of winter to be a symbol for Ethan. A reference coming from the Dictionary of Symbols by Jack Tresidder defines the season of winter; "Winter may appear as an old man by a fire or a bare-headed woman in a winter landscape. It is linked with Hephaestus (Vulcan) or Boreas, the salamander or wild duck, and Capricorn, Aquarius and Pisces." According to astrologers, Capricorns have responsible, disciplined, practical, methodical, cautious, serious, and sometimes pessimistic natures. According to astrologers, Aquariuses feel most comfortable in the world of ideas; they find situations that require emotional responses, such as personal relationships, to be difficult. Also, according to astrologers, Pisceans tend to be idealistic; sometimes the real world gets too harsh and ugly for them. To escape unpleasant realities, some Pisceans retreat into their own dreams and fantasies, and Pisceans can be delicate and vulnerable, especially when under emotional stress. Ethan most definitely falls under these categories. Ethan is emotionally weak, in that he allows Zeena to control him. Ethan was described, in the beginning of the book, as looking far older than he was in actuality. His work and torment made his physical appearance to match his inner suffering. Winter is typically seen as cold, dark, and lonely. These are reflective feelings succumbing Ethan. Love mostly suites those who remain oblivious to the harsh reality of our duty. Duty binds but love sets people free. Ethan realizes his duty, the duty of tradition, the duty to remain with Zeena. Ethan realizes this ...

How Laszlo Biro Changed the History of Ballpoint Pens

How Laszlo Biro Changed the History of Ballpoint Pens No man was more foolish when he had not a pen in his hand, or more wise when he had. Samuel Johnson. A Hungarian journalist named Laszlo Biro invented the first ballpoint pen in 1938. Biro had noticed that the ink used in newspaper printing dried quickly, leaving the paper smudge-free, so he decided to create a pen using the same type of ink. But the thicker ink wouldnt flow from a regular pen nib. Biro had to devise a new type of point. He did so by fitting his pen with a tiny ball bearing in its tip. As the pen moved along the paper, the ball rotated, picking up ink from the ink cartridge and leaving it on the paper.   Biros Patents This principle of the ballpoint pen actually dates back to an 1888 patent owned by John Loud for a product designed to mark leather, but this patent was commercially unexploited. Biro first patented his pen in 1938 and he applied for another  patent in June 1943 in Argentina after he and his brother emigrated there in 1940.   The British government bought the licensing rights to Biro’s patent during World War II. The British Royal Air Force needed a new pen that would not leak at higher altitudes in fighter planes the way fountain pens did. The ballpoint’s successful performance for the Air Force brought Biro’s pens into the limelight. Unfortunately, Biro had never gotten a U.S. patent for his pen, so another battle was just beginning even as World War II ended.   The Battle of the Ballpoint Pens   A lot of improvements were made to pens in general over the years, leading to a battle over the rights to Biros invention.  The newly-formed Eterpen Company in Argentina commercialized the Biro pen after the Biro brothers received their patents there. The press hailed the success of  their writing tool because it could write for a year without refilling. Then, in May 1945,  Eversharp Company teamed up with Eberhard-Faber to acquire exclusive rights to Biro Pens of Argentina. The pen was rebranded as the â€Å"Eversharp CA,† which stood for â€Å"capillary action.† It was released to the press months in advance of public sales. Less than a month after Eversharp/Eberhard closed the deal with Eterpen, a Chicago businessman, Milton Reynolds, visited Buenos Aires in June 1945.  He noticed the Biro pen while he was in a store and recognized the pen’s sales potential. He bought a few as samples and returned to America to launch the Reynolds International Pen Company, ignoring Eversharp’s patent rights. Reynolds copied the Biro pen within four months and began to sell his product by the end of October 1945. He called it Reynolds Rocket and made it available at Gimbel’s department store in New York City. Reynolds’ imitation beat Eversharp to market and it was immediately successful. Priced at $12.50 each, $100,000 worth of pens sold their first day on the market. Britain was not far behind. The Miles-Martin Pen Company sold the first ballpoint pens to the public there at Christmas 1945.   The Ballpoint Pen Becomes a Fad Ballpoint pens were guaranteed to write for two years without refilling and sellers claimed they were smear-proof. Reynolds advertised his pen as one that could write under water. Then Eversharp sued Reynolds for copying the design that Eversharp had acquired legally. The 1888 patent by John Loud would have invalidated everyones claims, but no one knew that at the time. Sales skyrocketed for both competitors, but Reynolds’ pen tended to leak and skip. It  often failed to write. Eversharp’s pen did not live up to its own advertisements either. A very high volume of pen returns occurred for both Eversharp and Reynolds. The ballpoint pen fad ended due to consumer unhappiness.  Frequent price wars, poor quality products, and heavy advertising costs hurt both companies by 1948. Sales nosedived.  The original $12.50 asking price dropped to less than 50 cents per pen. The Jotter   Meanwhile, fountain pens experienced a resurgence of their old popularity as Reynolds’ company folded. Then  Parker Pens introduced its first ballpoint pen, the Jotter, in January 1954. The Jotter wrote five times longer than the Eversharp or Reynolds pens. It had a variety of point sizes, a rotating cartridge, and large-capacity ink refills. Best of all, it worked. Parker sold 3.5 million Jotters at prices from $2.95 to $8.75 in less than a year. The Ballpoint Pen Battle Is Won   By 1957,  Parker had  introduced the tungsten carbide  textured ball bearing in their ballpoint pens. Eversharp was in deep financial trouble and tried to switch back to selling fountain pens. The company sold its pen division to Parker Pens and Eversharp finally liquidated its assets in the 1960s. Then Came Bic   The French Baron Bich dropped the ‘H’ from his name and began selling pens called BICs in 1950. By the late fifties,  BIC  held 70 percent of the European market.   BIC bought 60 percent of the New York-based Waterman Pens in 1958, and it owned  100 percent of Waterman Pens by 1960. The company sold ballpoint pens in the U.S. for 29 cents up to 69 cents. Ballpoint Pens Today   BIC  dominates the market in the 21st century. Parker, Sheaffer, and Waterman capture smaller upscale markets of fountain pens and expensive ballpoints.  The highly popular modern version of Laszlo Biros pen, the BIC Crystal, has a daily worldwide sales figure of 14 million pieces. Biro is still the generic name used for the ballpoint pen used  in most of the world.

Current Macroeconomic Situation Research Paper Example | Topics and Well Written Essays - 500 words

Current Macroeconomic Situation - Research Paper Example A problem that the global recession created which the U.S economy has not been able to manage well is an explosion in the unemployment rate. The unemployment rate in the U.S. traditionally used to be under 5%. The unemployment rate reached double figures in 2010 for the first time in decades. During the last few months the U.S. has gone down a bit which is a positive sign. The creation of jobs is very important for the economy because it provides much needed income to many American families. The graph below shows the movement in the U.S. unemployment rate during the past nine months. The United States population has not had any problems with inflation in recent history. Economies that suffer from inflation are problematic because inflation diminishes the purchasing power of money. A rise in inflation is also bad because it increases the cost of acquiring money from banks and lending institutions. Investors are not attracted by economies that suffer from inflationary tendencies. During 2009 and 2010 the inflation rate in the United States was a very low 0.92% and 1% (Countrywatch, 2012). A problem the U.S economy faces which affects the long term well being of its entire population is its overall deficit. The deficit of the Unites States is growing every year due to three factors. The three factors that are increasing the total debt of America are budget deficits, trade deficit, and a lack of savings. During the past 40 years the U.S has only been able to achieve a budgetary surplus five times. The deficits keep accumulating themselves year after year. The U.S also has the largest trade deficit in the world. In January 2012 the U.S economy generated $180.6 billion in exports and $233.4 billion in imports (Tradeeconomics, 2012). The end result was that the U.S. started the year by accumulating a trade deficit of $52.3 billion in January 2012. The United States fiscal policy should focus on expansionary policies. The

Using accelerometer and EMG signals to estimate arm motion Dissertation

Using accelerometer and EMG signals to estimate arm motion - Dissertation Example Using accelerometer and EMG signals to estimate arm motion This study investigates a means to overcome this degradation through use of EMG signals combined with accelerometer signals to measure the upper arm static and dynamic acceleration. Both EMG signal and accelerometer inputs are fed into an artificial neural network. The artificial neural network continuously predicts arm movement trajectories. An offline time-delay Artificial Neural network (TDANN) is employed to predict the movement trajectories of the arm. The accuracy of prediction was judged by using a set of goniometer readings which provides the changes in the angles of the upper limb. All data was processed in the Matlab environment. The TDANN deployed was developed in the neural network toolbox present within the Matlab environment. The developed neural network was optimized and trained with different sets of inputs, and the results for each of the trails was noted. The results obtained clearly demonstrated that accelerometers are able to enhance pattern recognition and thus p rovide better prosthesis control. Neural Network Optimization and Prediction Performance The neural network structure used for the study is the TDANN. TDANN is a neural network architecture whose primary purpose is to function on continuous data. The major advantage of using TDANN on continuous data is its ability to adapt the network’s weights and activation function online by use of back propagation error method. (Fougner, et al., 2011). The networks can be visualized as a feed forward neural network which is trained for time series prediction. The architecture has continuous inputs that are delayed and sent into the network. In this study, the inputs to this neural network architecture were delayed time series; that is the previous values of 10 channels for 4 for EMG and 6 channels for accelerometers. The measured goniometer signals served as desired output of the TDANN and also as the present state of the time series. The usage of one- layer time delay artificial neural n etwork which is a feed forward structure allow us to predict continuous trajectories which is advantageous for a coordinated and simultaneous control of multiple degrees of freedom in a natural manner. The use of delayed input signals enabled the neural network to capture dynamic input-output properties and account for the delay between the onset of the muscle activity and mechanical arm movement (the activation of the hardware motors in the prosthesis) (Fougner, et al., 2011). TDANN have also an advantage of rapid training time when compared to the dynamic neural networks with recurrent connections. We investigated using a TDANN to predict the elbow flexion degrees, wrist flexion degrees, wrist deviation degrees and forearm rotation degrees based on EMG information from the available intact muscles in transhumeral amputation patients. The EMG information was combined with the accelerometer information about the upper arm and the upper trunk orientations. A one layer time-delay arti ficial neural network (TDANN) was created using Matlab’s neural network toolbox; this network was used to capture the time-series data (EMG and accelerometer signals as an input with the goniometers and torsiometer signals as output). The size of the hidden layer was set by default to be 10 neurons and the network was trained then the hidden layer size was increased to 25 then to 35 and the performance of the network was monitored. TDANN with 35 neuron hidden layer size was then chosen. The network used 2 input delays to allow building a dynamic network, which has memory so

The Road to Disappearance Essay Example for Free

The Road to Disappearance Essay The Road to Disappearance: A history of the Creek Indians was written by Angie Debo, a native of Oklahoma. She had curiosity of the life and history of the â€Å"creek Indians’ which is also known as the ‘Muskigees’. These people are later on named as ‘Creek Indians’ because they thrive on the Creek areas or besides rivers and canals. This book was written in 1941, a part of many books about Creek Indians that was written by the author as she was teaching history in the University of Oklahoma. Basically, the book gives the reader the story of the ‘Creek history’. It covers the years from 1725 up until 1906. It tackles the experiences of the Creeks as a nation and their interaction and relationship with the Washington government as well as with the states that they occupy namely, Alabama, Georgia and Kansas. Throughout the book, the author kept on presenting data and facts that serves as evidence of her arguments regarding the fast paced obliteration of the ‘Creek Nation’. She also cited accounts of the attempts and struggles made by the Creeks as the State and Federal government draft laws that somehow keep these people marginalized and controlled. The first chapters in the book cover the discussion of the Creek Nation’s history, which, as Debo pronounced was ‘lost in legend’. There are those which talks about coming from the ‘huge mountains†¦a migration toward sunrise†¦ the crossing of a great and muddy river and the occupation and conquest of their eastern home’. These chapters also talks about the Creeks relation with other Indians and some of their customs, beliefs and practices. The third chapter offers the beginning of the destruction of the ‘Nation’ that was followed by conquers and the war with these conquerors. Chapter VI shows that after devastation, the ‘Creeks forms a nation again’, nonetheless the proceeding chapters shows and discuss rivalries and conflicts inside the ‘Nation’ itself. In chapter IX there was a moment of peace, nonetheless it does not stand for long as what Debo believes to be happening right now is the ending of the tribe. The book was well written and provides a good overview of the history of Indian Americans in general and Creek Nation in particular. It helps the readers understand what was the life that these people has to endure and the history that they have along with their distinct culture, beliefs and traditions that were slowly being eroded by modernization and ethno racism. The book was obviously in favor and in support of helping the Creek Indians get the rights, respect and recognition that they properly deserved. The author has successfully point out the different period in history that the Creeks have been oppressed and how the government policies are hurting and demeaning the Indian population. The author has successfully laid the foundation and evidence that will make the reader question the legitimacy of the laws and policies that the government has made in the past and today. It somehow expands the horizon of what I know about American Indians. Moreover it helps me understand their situation. The author made me feel how wrongly the Creek Indians are treated. Along with illustrations, the book successfully captures sympathy and understanding from its readers. This I think is the main purpose of the book aside from being informative. There are a lot of things that I have learned from the book aside from the different Indian tribes and the way they live. I also found about how they are treated and what their history in connection to my own is. Understanding the difference between us (the Creek Indians and me) and the fact that we are living in the same country, give me a higher regards and respect for their abilities and their being the real owners of the lands in which we (Americans) thrive. To further understand the book and to find the topics more easily, there an index at the end that can make reading easier especially when looking back and looking for terms in relation to other topics in the book. The book also contains maps aside from illustrations. These maps are important to help the reader’s picture in their mind the length and area that the Creek’s covers. There is also a page that contains other works created by Angie Debo which are also related to the ‘Creek Indians’. I definitely recommend this book for people who would like to know about the Creek’s life. It is thorough and it refers to the problems of the Creek in a straightforward manner. Although it is somehow bias, it delivers a good stance in regards to the life and the rights of the Creek people. The readers would enjoy the way the book is written eventhough it talks about history. The author has the ability to look at the subject matter in an inclusive perspective, such that the reader will feel as though they are pat of the history that they are reading. This is a must read for enthusiast and non enthusiast alike and I recommend it for a deeper understanding of the culture and the people that once been the sole owners and cultivators of the American land.

OXFAMs Global Reach :: Essays Papers

OXFAM's Global Reach "Consequences of the New Economy" was the theme for St. Olaf College's Globalization and Social Responsibility conference. The conference explored the social and economic effects of the globalization of capitalism. One of the speakers for this event was Raymond Offenheiser, a leader in international development and philanthropy, and president of OXFAM America. OXFAM America, an international nonprofit agency, is recognized for its human rights and national public education program on issues of hunger and injustice throughout the world. Offenheiser's lecture, OXFAM's Global Reach , addressed the increasing interdependence in global markets and its effects on agriculture, coffee, and fair trade. World trade has the potential to reduce poverty, if poor people could sell their products at a reasonable price. However, the injustices of the world trade system are stopping them. Unfair trade agreements and agricultural subsides hinder efforts to reduce poverty in poor countries. In particular, farm and trade policies in the United States and the European Union are creating adversities for family farmers worldwide. The world's wealthy countries provide a substantial amount of money to support agriculture, enabling corporate and large-scale farmers in these countries to grow more than is needed. The access is dumped on international markets, where it is sold for less than it costs to grow. This dumping drives down prices and destroys the livelihood of farmers in countries that do not subsidize farmers and are forced to open their markets to foreign commodities. Unfair trade and farm policies that allow dumping are a major cause of poverty, since many poor communities rely on agriculture as a major source of income. If farmers can't sell their crops for a fair price, they must leave their lands, their families, and migrate in search of jobs. American cotton subsidies are a prime example of how US agriculture and trade policies worsen poverty in Africa. These American subsides have greatly reduced world cotton prices, generating losses to African producers. Although West African cotton farmers are more efficient, low-cost producers they cannot compete with the US producers' access to huge subsidies. Consequently, the cotton price crisis is contributing to the poverty for millions of African farmers. Unfortunately, farm and trade policies do not help most small farmers in the United States either. Low world prices are quickly forcing US family farmers out of business, while large-scale, corporate agriculture benefits from government payments. The global coffee crisis is also creating hardships for families around the world.

Psychology and Social Support Essay

Marriage these days does not seem to last very long. Two months after his wedding, your friend Tom confides in you that he’s unhappy in his marriage. He tells you that he and his wife seem to be fighting all the time, and nothing seems to get resolved. He tends to be very high-strung anyway(His friends call him â€Å"Type-A Tom†) and now he feels like the stress of the constant bickering is affecting every aspect of his life, including his health. Since you’re in a Psychology class, he asks you for your thoughts on the chances of his marriage surviving and your advice about what he can do about his stress. Based on what you’ve read (either in the assigned readings in this module or your own Internet research), you answer his questions by addressing 10 factors that may be related to his situation. Briefly discuss each of these factors (and how it may relate to Tom’s predicament) in a 5-7 page essay. The Factors are: Predictability of the stressor. In psychology, stress is a feeling of strain and pressure. Symptoms may include a sense of being overwhelmed, feelings of anxiety, overall irritability, insecurity, nervousness, social withdrawal, loss of appetite, depression, panic attacks, exhaustion, high or low blood pressure, skin eruptions or rashes, insomnia, lack of sexual desire (sexual dysfunction), migraine, gastrointestinal difficulties (constipation or diarrhea), and for women, menstrual symptoms. It may also cause more serious conditions such as heart problems. Also, experimental research which has been performed on animals, also displayed results relating to stress and negative effects on the body. It has been shown that stress contributes to the initiation and development of specific tumors within the body. A stressor is any event, experience, or environmental stimulus that causes stress in an individual.[22] These events or experiences are perceived as threats or challenges to the individual and can be either physical or psychological. Researchers have found that stressors can make individuals more prone to both physical and psychological problems, including heart disease and anxiety.[23] Stressors are more likely to affect an individual’s health when they are â€Å"chronic, highly disruptive, or perceived as uncontrollable†.[23] In psychology, researchers generally classify the different types of stressors into four categories: 1) crises/catastrophes, 2) major life events, 3) daily hassles/microstressors, and 4) ambient stressors. Social support (human relationships) Social support is the perception and actuality that one is cared for, has assistance available from other people, and that one is part of a supportive social network. These supportive resources can be emotional (e.g., nurturance), tangible (e.g., financial assistance), informational (e.g., advice), or companionship (e.g., sense of belonging). Social support can be measured as the perception that one has assistance available, the actual received assistance, or the degree to which a person is integrated in a social network. Support can come from many sources, such as family, friends, pets, organizations, coworkers, etc. Government provided social support is often referred to as Public aid.

How Graduate Admission Committees Evaluate Applications

How Graduate Admission Committees Evaluate Applications Graduate programs receive dozens or even hundreds of applications and many are from students with stellar qualifications. Can admissions committees and departments really draw distinctions among hundreds of applicants? A competitive program that receives a large number of applications, such as a doctoral program in clinical  psychology, may receive up to 500 applications. Admissions committees for competitive graduate programs break the review process into several steps. First Step: Screening Does the applicant meet the minimum requirements? Standardized test scores? GPA? Relevant experience? Is the application complete, including admissions essays and recommendation letters? The purpose of this initial review is to ruthlessly weed out applicants. Second Step: First Pass Graduate programs vary, but many competitive programs send batches of applications to faculty for an initial review. Each faculty member may review a set of applications and identify those with promise. Third Step: Batch Review In the next step batches of applications are sent to two to three faculty. At this stage, applications are evaluated with regard to motivation, experience, documentation (essays, letters), and overall promise. Depending on the size of the program and applicant pool the resulting set of applicants is reviewed by a larger set of faculty, or interviewed, or accepted (some programs do not conduct interviews). Fourth Step: Interview Interviews may be conducted by phone or in-person. Applicants are evaluated with regard to their academic promise, thinking and problem-solving skills, and social competence. Both faculty and graduate students evaluate applicants. Final Step: Post Interview and Decision Faculty meet, gather evaluations, and make admissions decisions. The specific process varies depending on the size of the program and number of applicants. Whats the takeaway message? Make sure that your application is complete. If youre missing a recommendation letter, essay, or transcript, your application will not make it through the initial screening.

Biography of Samuel Morse, Inventor of the Telegraph

Biography of Samuel Morse, Inventor of the Telegraph Samuel Finley Breese Morse (April 27, 1791–April 2, 1872) is famous as the inventor of the telegraph and Morse Code, but what he really wanted to do was paint. He was a well-established artist when his youthful interest in electronics resurfaced, leading to the communications invention that changed humanity until it was overshadowed by the telephone, radio, television, and, finally, the internet. Fast Facts: Samuel F.B. Morse Known For: Inventor of the telegraphBorn: April 27, 1791 in Charlestown, MassachusettsParents: Jedidiah Morse, Elizabeth Ann Finley BreeseDied: April 2, 1872 in New York, New YorkEducation: Yale College (now Yale University)Spouse(s): Lucretia Pickering Walker, Sarah Elizabeth GriswoldChildren: Susan, Charles, James, Samuel, Cornelia, William, EdwardNotable Quote: What hath God wrought? Early Life and Education Samuel F.B. Morse was born on April 27, 1791, in Charlestown, Massachusetts, the first child of noted geographer and Congregational minister Jedidiah Morse and Elizabeth Ann Finley Breese. His parents were committed to his schooling and the Calvinist faith. His early education at Phillips Academy in Andover, Massachusetts, was undistinguished, except for his interest in art. He next enrolled in Yale College (now Yale University) at age 14, where he focused on art but found a new interest in the little-studied subject of electricity. He earned money by painting small portraits of friends, classmates, and teachers before graduating in 1810 with Phi Beta Kappa honors. He returned to Charlestown after college. Despite his wishes to be a painter and encouragement from famed American painter Washington Allston, Morses parents wanted him to be a booksellers apprentice. He became a clerk for Daniel Mallory, his fathers Boston book publisher. Trip to England A year later, Morses parents relented and let him sail to England with Allston. He attended the Royal Academy of Arts in London and received instruction from Pennsylvania-born painter Benjamin West. Morse became friends with poet Samuel Taylor Coleridge, several accomplished painters, and American actor John Howard Payne. He adopted a â€Å"romantic† painting style featuring heroic characters and epic events.  In 1812, his plaster statuette The Dying Hercules won a gold medal at the Adelphi Society of Arts exhibition in London, and his painting of the same subject received critical acclaim at the Royal Academy. Family Morse returned to the U.S. in 1815 and opened an art studio in Boston. The next year, seeking portrait commissions to earn a living, he traveled to New Hampshire and met Lucretia Pickering Walker, 16, in Concord. They soon became engaged. Morse painted some of his most notable work at this time, including portraits of military leader  Marquis de Lafayette  and President  George Washington.   On Sept. 29, 1818, Lucretia Walker and Morse were married in Concord. Morse spent the winter in Charleston, South Carolina, and received many portrait commissions there. The couple spent the rest of the year painting in Portsmouth, New Hampshire. A year later, Morses first child was born. While living with his family in New Haven, Connecticut, in 1821, Morse painted more distinguished individuals, including cotton gin inventor Eli Whitney and dictionary compiler Noah Webster. Morses second child was born in 1823 and his third child arrived two years later, but tragedy followed. One month after the birth of his third child, Lucretia Morse died suddenly at age 25 and was buried in New Haven before he could return. Interest in Electricity Resurfaces In 1827, Columbia College Professor James Freeman Dana presented a series of lectures on electricity and electromagnetism at the New York Athenaeum, where Morse also lectured. Through their friendship, Morse became more familiar with the properties of his earlier interest. In November 1829, leaving his children in the care of relatives, Morse left for a three-year tour of Europe, where he visited friends Lafayette and novelist James Fenimore Cooper, studied art collections, and painted. While raising his family, painting, lecturing on art, and viewing works by the old masters, Morses fascination with electronics and inventions never disappeared. In 1817, he and his brother Sidney patented a human-powered water pump for fire engines that worked but was a commercial failure. Five years later, Morse invented a marble-cutting machine that could carve three-dimensional sculptures, but it couldnt be patented because it infringed on an earlier design. Meanwhile, advances in electronics had been moving the world closer to a device that could send messages over vast distances. In 1825, British physicist and inventor William Sturgeon invented the electromagnet, which would be a key component of the telegraph. Six years later, American scientist Joseph Henry developed a more powerful electromagnet and demonstrated how it could send electric signals over long distances, suggesting the possibility of a device such as the telegraph. In 1832, on his voyage home from Europe, Morse conceived the idea of an electromagnetic telegraph during conversations with another passenger, a doctor who described to Morse European experiments with electromagnetism. Inspired, Morse wrote in his sketchbook ideas for a prototype of an electromagnetic recording telegraph and a dot-and-dash code system that would bear his name. Later that year, Morse was appointed professor of painting and sculpture at the University of the City of New York (now New York University), but he continued to work on the telegraph. Developing the Telegraph In the fall of 1835, Morse built a recording telegraph with a moving paper ribbon and demonstrated it to friends and acquaintances. The next year he demonstrated his prototype to a professor of science at the university. Over the next several years, Morse demonstrated his invention to friends, professors, a House of Representatives committee, President Martin Van Buren, and his cabinet. He took on several partners who helped with the science and financing, but his work also began to attract competitors. On Sept. 28, 1837, Morse began the patent process for the telegraph. By November he was able to send a message through 10 miles of wire arranged on reels in a university lecture room. The next month, after completing the paintings he was working on, Morse set aside his art to devote his full attention to the telegraph. At this point, other men- including the doctor on Morses 1832 return voyage from Europe and several European inventors- were claiming credit for the telegraph. The claims were resolved and in 1840 Morse was granted a U.S. patent for his device. Lines were strung between many cities, and on May 24, 1844, Morse sent his famous message- What hath God wrought?- from the Supreme Court chamber in Washington, D.C., to the B O Railroad Depot in Baltimore, Maryland. By 1849, an estimated 12,000 miles of telegraph lines were being run by 20 American companies in the United States. In 1854, the Supreme Court upheld Morses patent claims, meaning that all U.S. companies using his system had to pay him royalties. On Oct. 24, 1861, Western Union completed the first transcontinental telegraph line to California. After several breaks, a permanent undersea Atlantic Cable was finally laid in 1866. New Family Back in 1847 Morse, already a wealthy man, had bought Locust Grove, an estate overlooking the Hudson River near Poughkeepsie, New York. The next year he married Sarah Elizabeth Griswold, a second cousin 26 years his junior. The couple had four children together. In the 1850s, he built an Italian villa-style mansion on the Locust Grove property and spent his summers there with his large family of children and grandchildren, returning each winter to his brownstone in New York. Death On April 2, 1872, Samuel Morse died in New York. He was buried in Greenwood Cemetery in Brooklyn. Legacy Morses invention changed the world, as it was used by the military during engagements, newspaper reporters filing stories from the field, far-flung businesses, and others.

Mu2 - Essay Example They should be taught how to deal with panicky situations, how to deal with emergency and to how to address their safety in such undesirable circumstances. Life safety is very important and given the context, it means trying to curb down un-necessary exposure to the harmful products due to combustion. There are three basic directions that need to be followed. The first one is to try stopping ignition, the second one is to control the outbreak of fire and the third one is to keep the humans safe from the byproducts of combustion. This can be done keeping in mind the concepts of either of the three of time, distance and shielding. The smoke and heat don’t develop instantaneously. They develop over time to create a harmful hazardous environment. There are a lot of variables involved and each of these variables varies in different circumstances so the rate at which this happens can’t be exactly predicted. The fire starts of as small and slowly gradually intensifies thus invoking a very hazardous environment in the process. The fire can be detected by either of the 2, through automatic means or by personnel detection. The real focus should be on what stage after ignition and heat buildup has the fire been discovered. It is that stage which will have a major impact on the life safety measures that would be taken up. It is not necessary that all the occupants at the site of the fire will react to it in the same way. The reaction of two different people will vary. The reaction of a single individual can also vary in different time frames, in different settings. It is not necessary that someone who reacts in a particular way at one point in time will react in exactly the same way three days from now. By reaction, it is meant, how humans react to smoke build up, to the flame, to the burns, to the hue and cry etc. There are some factors that help determine how humans react to fire situations typically. These factors are: Where age is concerned, the

The Story of Arthur Wergs Mitchell Essay Example | Topics and Well Written Essays - 1000 words

The Story of Arthur Wergs Mitchell - Essay Example Arthur Wergs Mitchell was born on December 22 1883, at Roanoke, Alabama and was the son of former slaves Taylor and Ammar Mitchell. His father has worked as a modest farmer to raise his family. Mitchell studied in public schools and has financed his college education at the Tuskegee Institute by working as a university assistant and farm laborer. After a year at the Tuskegee Institute, Mitchell transferred to Snow Hill Institute, where he was mentored by a Washington protà ©gà © in the person of Professor William J. Edwards. Mitchell’s beliefs toward his own teaching skills and capabilities have later on led him to putting up a vocational elementary school, the West Alabama Normal and Industrial Institute that was exclusive for African American children. These milestones have also brought difficulties to the life of Mitchell. He was accused of deceiving the poor blacks to working for cheap labor and was even charged of defrauding them to obtain their land titles. He was sued by the black farmers, but has managed to avoid prosecution. Nonetheless, the charges filed against Mitchell did not hinder him to moving toward his goal of becoming a lawyer. Eventually, Mitchell has left Alabama and moved to Washington. Then, he went to Chicago to pursue law. On 1919, he has moved to Washington D.C., where he has tried to familiarize himself with the law and has gone to real estate by establishing the Mutual Housing Company of Washington D.C (Asseln 1995). In spite of his lack of formal law education, Mitchell passed the bar in Chicago, Illinois in 1927 (Asseln 1995). He has later on ventured into the practice of law by opening a law office that has paved the way for him to creating a connection with the Republican Party (Asseln 1995). This then marked the beginning of his political career as the first African American democrat in the country. Mitchell has worked for the Republican Party and has managed the campaign of the Republican presidential bet Herbert Hoover (Nordin 2007). This responsibility has made him inspired to entering the arena of politics. Upon joining politics, Mitchell left the Republican Party and became a Democrat. As a democrat, he had the advantage of representing the black community, for he was seen by the party leader as one who will not intrude in the plans of the white political leaders that may be unfavorable for the black constituents (Nordin 2007). Arthur Mitchell replaced Harry Brooke as candidate of the Democratic Party for Congress Representative due to his sudden death (Arthur Wergs Mitchell 2013). Mitchell rivaled with fellow African American Oscar De Priest, but Mitchell managed to defeat Brooke, thereby, electing him as the very first African American Democrat to represent a state in the American Congress in November 7, 1934 (Arthur Wergs Mitchell 2013). Mitchell expressed his support to â€Å"President Roosevelt and the New Deal† during his tenure in Congress (Arthur Wergs Mitchell 2013). On the one hand, Mitchell got involved in a controversy that prompted him to file charges against the Illinois Central and Rock Island Railroads. The
