persian war essays

persian war essays A long time ago Croesus the king of Lydia took over the Greek colonies on the east coast of Asia Minor (Turkey). Croesus was a kind and fair ruler so the Greeks did not really mind. But around 546 BC King Croesus and his empire was overthrown by Cyrus the Great About fifty years later Asia Minor revolted against Persia. The rebellion was assisted by Athens. The rebellion was successful. After the rebellion had stopped Darius I took complete control over Asia Minor. Darius sent tyrants to rule over all Greek city states except Athens and Sparta refused to accept the tyrants. After Darius took rule the Ionian city states rebelled another time. Darius took this as a personal insult and sent troops in to destroy Athens. Athens beat the Persians whose army was almost three times the size of the Athenian army at the famous Battle of Marathon. The battle was fought on the Plains of Marathon outside of Athens. Darius' successor Xerxes I brought together the largest army of ancient history. In 480 BC Xerxes led his troops to the narrow passes of Thermopylae. In this battle several thousand soldiers led by the Spartan leader Leonidas I fought against the Spartans. A Greek traitor told the Persians a way to get around the Greek forces and enter the pass through their flank. The Persians did so and annihilated the Greek forces from the rear. There was nothing left between the Persians and Athens so the Persians plundered and destroyed the abandoned city. The next battle that took place was when the Persian fleet tried to pursue the Greek fleet at the Battle of Salamis. The Persians did not stand a chance in that battle and lost. All the Persian forces left in Greece were defeated a year later at the Battle of Plataea and Greece won ...

Computer Models Show How a Black Hole Eats a Star

Computer Models Show How a Black Hole Eats a Star Were all fascinated with black holes. We ask astronomers about them, we read about them in the news. and they show up in TV shows and movies.  However, for all our curiosity about these cosmic beasts, we still dont know everything about them. They flout the rules by being hard to study and detect. Astronomers are still figuring out the exact mechanics of how stellar black holes form when massive stars die. All this is made tougher by the fact that we havent seen one up close. Getting near one (if we could) would be very hazardous. No one would survive even a close brush with one of these high-gravity monsters. So, astronomers do what they can to understand them from a distance. They use light (visible, x-ray, radio, and ultraviolet emissions)  that come from the region around the black hole to make some very shrewd deductions about its mass, spin, its jet,  and other characteristics. Then, they feed all this into computer programs designed to model black hole activity.Computer models based on actual observational data of black holes help them to simulate what happens at black holes, particularly when one gobbles something up. What Does a Black Hole ComputerModel Show Us? Lets say that somewhere in the universe, at the  center of a galaxy like our own Milky Way, theres a black hole. Suddenly an intense flash of radiation flares out from the area of the black hole. What has happened? A nearby star has wandered into accretion disk (the disk of material spiraling into the black hole), crossed the event horizon (the gravitational point of no return around a black hole), and is torn apart by the intense gravitational pull. The stellar gases are heated up as the star is shredded  and that flash of radiation is its last communication to the outside world before it is lost forever. The Tell-Tale Radiation Signature Those radiation signatures are important clues to the very existence of a black hole, which does not give off any radiation of its own. All the radiation we see is coming from the objects and material around it. So, astronomers look for the telltale radiation signatures of matter being gobbled up by black holes:  x-rays or radio emissions, since the events that emit them are very energetic.   After studying black holes in distant galaxies, astronomers noticed that some galaxies suddenly brighten up at their cores and then slowly dim down. The characteristics of the light given off and the dim-down time came to be known as signatures of black hole accretion disks eating nearby stars and gas clouds and giving off radiation. It was, as one astronomer said, Like a black hole putting up a sign that said, Here I am!! Data Makethe Model With enough data on these flareups at the hearts of galaxies, astronomers can use supercomputers  to simulate the dynamic forces at work in the region around a supermassive black hole. What theyve found tells us much about how these black holes work and how often they light up their galactic hosts. For example, a galaxy like our Milky Way with its central black hole might gobble up an average of one star every 10,000 years. The flare of radiation from such a feast fades very quickly, so if we miss the show, we might not see it again for quite a long time. But, there are many galaxies, and so astronomers survey as many as possible to look for radiation outbursts. In the coming years, astronomers will be deluged with data from such projects as Pan-STARRS, GALEX, the Palomar Transient Factory, and other upcoming astronomical surveys. There will be  hundreds of events in their data sets  to explore. That should really boost our  understanding of black holes and the stars around them. Computer models will continue to play a large part in delving into the continuing mysteries of these cosmic monsters.

Statement of Purpose + Autobiography Essay Example | Topics and Well Written Essays - 1250 words

Statement of Purpose + Autobiography - Essay Example The testimonies of students do attest to a driven and highly respected learning community; the presence of a culture that fosters innovation and academic contribution; and having a highly competent faculty. Perhaps, the most appealing feature of the graduate programs that Fielding offers is the establishment of nurturing mentoring relationships with the students. I am a strong advocate of coaching and mentoring, and do believe that a post graduate student should be accountable for his or her learning as well. Its reputation is attested to by its accolades. For one, it is the sole program in clinical psychology that is acknowledged and certified by the American Psychological Association. Moreover, it explicitly expresses its intent to teach out of the box, and beyond the conventional graduate programs offered by similar learning institutions. Since I am strongly for innovation as a value, I would like to be part of a learning community that similarly attaches premium to out-of-box thinking. Moreover, in future practice, both in the professional and research spheres, I would like to explore more non-traditional counseling areas where I can add the most value. Yet another personal advocacy that I have is the respect for diversity, which is also apparently espoused by Fielding. The site indicates that Fieldings Clinical Psychology program " brings a rich diversity of prior learning and professional experience with backgrounds in psychology and many students have experience as therapists and counselors". I believe that interaction with individuals of varying backgrounds will make the learning experience richer, as it will permit you to evaluate issues and insights from differing perspectives. I plan to be as inclusive as possible in my practice, helping as many people as I can possibly can. In fact, I have a strong leaning towards helping indigents. Fielding has acknowledged the

Marketing Audit on a 1 shop Essay Example | Topics and Well Written Essays - 2750 words

Marketing Audit on a 1 shop - Essay Example According to the figures released earlier this year, Poundland reported an 81.5% increase in profits from the previous year. Poundworld posted record profits of ?5.4m in on sales of ?133m. Buying from these pound points provides incredible value for money to the consumers, and with budgets stretched, it makes pound shops very preferable for them. The low prices are made possible due to low costs incurred in their model, by these shops. A conscious effort to keep a check on costs is made, in terms of overhead expenses and direct costs. Pound shops are able to save large chunk of money by buying in bulk quantities. They don’t shelve varieties for their products, but usually stack on products from one or two manufacturers for each category. This allows them a lot of bargaining power with the suppliers. Since they only have to stock few varieties for each product category, they can always switch to those suppliers that offer the lowest rates. Even renowned brands have supplied the ir products to pound shops, recently. Pound shops’ model is based on keeping prices at the low price points, ensuring there’s price consistency across the shop, and which continues overtime. This creates greater certainty for the customers, who confidently return to the shop, knowing they would be able to shop without draining on their low budgets. For the administration too, it’s a relief, since they don’t have to spend time and hire resources, to calculate prices for each product item. All product items can be arranged anywhere in the shop, and rearranged to change the display, without worrying about changing tags, or shelves. Pound shops also don’t undergo price inflation. This certainty gives them a rare advantage over other consumer retail and other avenues of consumers’ pounds, where inflation can be a huge drain on consumers’ already limited incomes. Pound shops try to absorb inflation by negotiating harder with suppliers so th ey continue getting products at same level of prices. Alternatively, they might switch to another supplier, which, however, could be offering products which are inferior to those previously offered. However, at times, pound shops have been known to counter inflation by other means too. Instead of increasing prices, they have reduced the quantity of product offered. 99p Stores, for instance, were selling 200g Toblerones but later the chocolate bars were only 170g in weight. In general, however, the zero-price inflation, price consistency, and of course low prices, ensure a large customer base for pound shops. In times of recession and low economic growth, when wages don’t increase by much, if at all, low wage earners find pound shops extremely valuable. When unemployment is relatively high, more people are living off benefits. Middle and upper classes too feel compelled to look for value in their shopping, and then there are students and other such groups of consumers who are very conscious about their spending. With their unique business model, pound shops are able to reach out to, and cater to, a larger customer base than other retailers. Pound shops also employ an effective tool in their marketing mixes- that of psychological pricing, in pricing. 99c is a successful price point chain in UK, and others also use the psychological pricing effectively, to give the consumer the perception of greater value for money. In terms

The Components of Criminal Justice Essay Example for Free

The Components of Criminal Justice Essay There are three main components of understanding the components of criminal justice. They are law enforcement, courts, and corrections. First is law enforcement, it broadly refers to any system by which some members of society act in an organized manner to promote adherence to the law by punishing people who violate the rules governing that society. However, the term may encompass entities such as courts and prisons, it is most frequently applied to those who directly engage in patrols or surveillance to dissuade and discover criminal activity, and those who investigate crimes and apprehend offenders. Next are courts. It’s a tribunal, often a governmental institution, with the authority to adjudicate legal disputes between parties and carry out the administration of justice in civil, criminal, and administrative matters in accordance with the rule of law. The third and final component of the criminal justice system is corrections. The role of this component is to uphold and administer sentences handed down by judges. The corrections system, which is tightly intertwined with the previous two components, is very important and quite large. The corrections component includes jails, prisons, correctional officers, probation officers and parole officers. Criminal procedures are safeguards against the indiscriminate application of criminal laws and the wanton treatment of suspected criminals. Specifically, they are designed to enforce the constitutional rights of criminal suspects and defendants, beginning with initial police contact and continuing through arrest, investigation, trial, sentencing, and appeals. The U.S. Supreme Court, pursuant to its authority under the Rules Enabling Act, first promulgated the Federal Rules of Criminal Procedure, which Congress, in turn, passed. The Federal Rules outline the procedure for conducting federal criminal trials. Similarly, states have their own codes of criminal procedure of which many closely model the Federal Rules. The Federal Rules incorporate and expound upon all guarantees included within the U.S. Constitutions Bill of Rights. A few of the rights guaranteed to criminal defendants by the Constitution include the guarantees of due process and equal protection under the laws, the right to have legal counsel present, the right to confront witnesses, the right to a jury trial, and the right to not testify against oneself. While state constitutions and procedural rules may increase the protection afforded to criminal defendants, they may not offer less protection than that guaranteed by the U.S. Constitution. According to Freedictionary, policing is to regulate, control, or keep in order with or as if with a law enforcement agency and to make (a military area, for example) neat in appearance: policed the barracks. On the other hand, community policing is a philosophy that promotes organizational strategies, which support the systematic use of partnerships and problem-solving techniques, to proactively address the immediate conditions that give rise to public safety issues such as crime, social disorder, and fear of crime. Corrections are a euphemism. It’s a less distasteful word chosen to represent jails and prisons. For many professionals involved in the justice system, though, the word represents a hope that the people they deal with can learn from their mistakes and return to society as productive citizens. The history of corrections is full of various interpretations of the purposes of removing criminals from societya debate that continues in todays theories of corrections. Penology comes from the Latin word poena, punishment and the suffix -logy, study of. It is a section of criminology that deals with the philosophy and practice of various societies in their attempts to repress criminal activities, and satisfy public opinion via an appropriate treatment regime for persons convicted of criminal offenses. Ethical issues in criminal justice have been addressed on both a philosophical and historical level. Ethical issues have existed in relation to government, policing and international politics for centuries. The standard code of ethics that law enforcement personnel and public servants are asked to uphold can often be translated subjectively by individuals, resulting in the possibility of ethically questionable conduct. Ethical issues regarding brutality, corruption and off-duty behavior have become an increasing challenge in criminal justice.

Wind Power Essay -- Wind Power Energy Sources Essays

Wind Power Harnessing the natural power of the wind is by no means a new concept. Asides from sailing, wind power has been utilised for many thousands of years, principally for agricultural purposes. Basic windmills are thought to have been used in Persia (now Iran) as early as the 7th century AD. Their ability to make use of otherwise untapped energy sources without the needs and costs of other alternatives, ensured that they remained the machines of preference in several industries throughout both agricultural and industrial revolutions. Whilst their basic concepts have remained true to the basic origins, technological advances have enabled engineers to adapt the mechanics of the mill to enable a more functional and useable source of power. In the 18th C, engineers developed spring sails (a device incorporating shutters onto the sails) to enable the mill to be run at constant speed during variable wind speeds automatically. The development of the fantail in 1745 also ensured the mills ran in the face of the wind and along with airbrakes meant that the mill could run at its most efficient at all times without the risk of doing itself damage in strong winds. Uses developed into water pumping, wood sawing, papermaking, pressing oil seeds and a variety of grinding uses. The use of wind turbines for generating electricity was pioneered in Denmark late in the 1890s. The concept was made a reality by Poul la Cour (1846-1908) who had originally trained as a meteorologist. He built the world's first electricity generating wind turbine in 1891 and although his project was a success, decided the greatest problem lay in storage of the electricity. As a result he used the electricity from his turbines for electrolysis in order to produce hydrogen for the gas lighting in his school.  ¡Ã‚ §One basic drawback of this scheme was the fact that he had to replace the windows of several school buildings numerous times, as the hydrogen exploded due to small amounts of oxygen in the gas (!) ¡Ã‚ ¨ DWTMA. As technological barriers were worked through, wind turbines became increasingly complicated. One of the greatest developments was the use of aerofoils instead of angled blades.

Reading Maketh a Full Man Essay

Did you know that there are nearly 800 million people around the world today who cannot read? All 320 of us can, but so many others can’t. And that’s when we realize just how important reading really is. Good morning, respected judges, teachers and dear friends. My name is Merlin Raphael and I’m here to talk about how reading makes a man. There was a time, without any screens, when reading was a popular leisure activity. People would spend hours reading and travelling to distant, exotic lands -in their minds, with only a leather bound book. But somewhere along the road, the passion to read is lost. And that’s just sad because reading offers a completely new life. Sir Francis Bacon, once said, and I quote, â€Å"Reading maketh a full man.† And he couldn’t be more correct. Reading involves a considerable level of concentration and thus, nurtures patience. Such an indulgence constantly elevates one’s vocabulary and knowledge. In fact, the habit can become a healthy addiction and helps us to stay in-touch with contemporary writers as well as those from the past. It also helps us to deal with issues of the modern world. Reading different types of texts make an even fuller man. What I mean is that he kind of knowledge you get from news articles is very different from reading stories. Being ignorant can be prevented with reading. It opens this huge wooden window and we finally start understanding other people and their lives. And a deeper awareness leads to tolerance and respect, creating a more civilized society. Furthermore, when one is caught up in a book, one comes across an array of emotions and somewhere in the middle; we find the sheer happiness of the reader. Lack of reading in one’s life can hinder gaining new knowledge, professional growth and the pure pleasure of reading. After all, no reading might even disturb one’s integrity. According to Confucius, we must find time for reading or surrender to â€Å"self-chosen ignorance†. You guys, reading is not merely a process of examining and understanding a text. There is a certain aura of finesse around one who reads. If a person can obtain so much from it, I think it’s safe to say that reading make a man.

A regular turn in American sign language Essay

In the next example, the Professor is suggesting that the next step is to separate portions of the Student’s narrative into chunks. She explains that narrative chunks in spoken languages are detected through linguistic cues, such as rhythm, intonation, and discourse markers (Chafe 1982). She concludes by saying that she does not know if ASL has these cues or if there are other kinds of cues. Her final remark, Ð ° rhetorical question, is interpreted into ASL as Ð ° direct question: Does ASL has cues? The Student immediately responds, â€Å"YES† The Professor’s delay at hearing Ð ° response is minimal, less than Ð ° half second. The briefness of this delay accounts for the illusion that the speakers are almost talking to each other, Because the Student begins to respond in ASL by the second potential turn transition, the exchange between Professor, Student, and Interpreter occurs seemingly naturally within Ð ° brief time span and without problems. That primary speakers are responding to the Interpreter in terms of the norms of their own language is also demonstrated by their nonverbal behavior. Both speaker’s nod their heads, smile and silently laugh, and make other gestures at moments that co-occur with utterances they understand in their own languages. For example, later in the meeting when the Professor learns that the Student will be going to another city to give Ð ° speech, she smiles and nods, but these expressions occur after she hears the interpretation in English, not after the Student says it in ASL. one wonders, then, whether the Student understands, intuitively or not, that the nonverbal information he sees the Professor engage in at that moment is attached to what he said moments ago noted that when people speak the same language, they know what facial signals go with what words and so can interpret the combination of the two signals. But when we interact with people who speak another language, any speaker might observe another speaker’s body and facial cues but most likely cannot associate these cues with their exact words, sentence, or meanings. In this section І have demonstrated how the Student and the Professor take turns at potential transition moments within their own language, and thus, with the Interpreter. Regular turns occur naturally in face-to-face interaction, and they also occur naturally in interpreting. The participants, the discourse, and the moment combine (McDermott and Tylbor [1983] call this â€Å"collusion†) to create interactional harmony whereby Ð ° turn happens successfully and comfortably. In regular turns, then, the Interpreter is an active participant who constructed equivalent responses in terms of message content and also in terms of potential turn transition. Knowing when and how to signal turns or pauses is discourse knowledge and an indication of communicative competence. Creating Turns From studies of no interpreted conversations, we know that speakers do not take turns or continue their turns only because they recognize Ð ° transition moment or Ð ° specific syntactic unit that allows for exchange. Bennett (1981) suggests that the structural regularities in discourse and Ð ° participant’s understandings of the thematic flow of the discourse make turn units â€Å"considerably more flexible† (emphasis his) than the notion of turns created solely from structural surface signals. Within conversations, participants create themes which unfold, diverge, and reconverge as the talk proceeds (Bennett 1981). Themes comprised of individual and shared motives, feelings about the subject, and the meanings that are uttered direct conversational contributions Turns, then, also come about through participants’ intuitive sense of â€Å"now† being the right moment to speak, or take Ð ° turn. After playing back the videotape of the meeting once, І asked the participants to focus on turn-taking. І asked them to recall, if they could, their motives and feelings around their turns, and why, in some places, they chose to speak. Predictably, their own reasons for taking Ð ° turn or continuing Ð ° turn were based in large part on their own sense of participation in the conversation and from Ð ° sense of wanting either to contribute to Ð ° theme or, in one case, to stop Ð ° theme. These developments are not predictable but are Ð ° part of conversational behavior. Moreover, the ways in which the interlocutors contribute to the flow constitutes an emerging pattern of conversational style (Tannen 1984). For example, at one point in the meeting, the Professor began to talk even though she could hear an interpretation. During her interview, І asked the Professor about this segment. Her response was, â€Å"І probably just decided it [the Student’s talk] was enough. І didn’t especially want to hear the answer now. І just wanted to set it as Ð ° topic that would be interesting for him to think about and report on during the semester. † The Professor began to talk from her own sense of the direction of the conversation and her desire to have the Student think about the topic and not initiate Ð ° longer discussion at present. To steer the conversation in Ð ° different direction and perhaps head off Ð ° lengthy discussion, she took Ð ° turn from her own sense of needing to alter the theme of the conversation, not from Ð ° surface syntactic signal. In another example, at the beginning of the meeting, the Student was looking at the Interpreter because the Interpreter was signing, and then he turned away from the Interpreter and looked toward the Professor and the telephone and answering machine. He began to talk while the Interpreter was still interpreting, not at Ð ° potential transition moment in ASL. His turn, too, has to be motivated by reasons other than an approaching grammatical unit or paralinguistic signal. When asked why he stopped watching the Interpreter and began to speak, the Student replied, â€Å"І knew where [the Interpreter] was going; І could sense the way his sentence would end. І wanted to see what she was doing to make the phone stop ringing. † (This he had learned from what the Professor had just said. ) Discourse knowledge, real world knowledge, Ð ° sense of conversational direction, speaker intention, and many other factors motivate speakers to take turns. Although interpreters cannot always predict when Ð ° speaker will talk, they can become accustomed to the possibilities of change and that turns can occur at the least likely moments, or rather, at any moment. Primary participants are actively involved in creating and responding to turns, and, for all intents and purposes, make arbitrary decisions which must be managed by an interpreter. More significantly, these examples demonstrate that primary participants are active in the emerging nature and flow of talk as the interpreter directs and coordinates the exchange.

Major General Winfield Scott Hancock - Biography

Major General Winfield Scott Hancock - Biography Winfield Scott Hancock - Early Life Career: Winfield Scott Hancock and his identical twin, Hilary Baker Hancock, were born February 14, 1824 at Montgomery Square, PA, just northwest of Philadelphia. The son of school teacher, and later lawyer, Benjamin Franklin Hancock, he was named for noted War of 1812 commander Winfield Scott. Educated locally, Hancock received an appointment to West Point in 1840 with the aid of Congressman Joseph Fornance. A pedestrian student, Hancock graduated in 1844 ranked 18th in a class of 25. This academic performance earned him an assignment to the infantry and was commissioned as a brevet second lieutenant. Winfield Scott Hancock - In Mexico: Ordered to join the 6th US Infantry, Hancock saw duty in the Red River Valley. With the outbreak of the Mexican-American War in 1846, he received orders to oversee recruiting efforts in Kentucky. Successfully fulfilling his assignment, he continually requested permission to join his unit at the front. This was granted and he rejoined the 6th Infantry at Puebla, Mexico in July 1847. Marching as part of his namesakes army, Hancock first saw combat at Contreras and Churubusco in late August. Distinguishing himself, he earned a brevet promotion to first lieutenant. Wounded in the knee during the latter action, he was able to lead his men during the Battle of Molino del Rey on September 8 but soon was overcome by fever. This prevented him from taking part in the Battle of Chapultepec and capture of Mexico City. Recovering, Hancock remained in Mexico with his regiment until the signing of the Treaty of Guadalupe Hidalgo in early 1848. With the end of the conflict, Hancock returned to the United States and saw peacetime duty at Fort Snelling, MN and St. Louis, MO. While in St. Louis, he met and married Almira Russell (m. January 24, 1850). Winfield Scott Hancock - Antebellum Service: Promoted to captain in 1855, he received orders to serve as the quartermaster at Fort Myers, FL. In this role he supported US Army actions during the Third Seminole War, but did not take part in the fighting. As operations wound down in Florida, Hancock was transferred to Fort Leavenworth, KS where he aided in combating partisan fighting during the Bleeding Kansas crisis. After a brief period in Utah, Hancock was ordered to southern California in November 1858. Arriving there, he served as assistant quartermaster under future Confederate commander Brigadier General Albert Sidney Johnston. Winfield Scott Hancock - The Civil War: An avowed Democrat, Hancock befriended many Southern officers while in California, including Captain Lewis A. Armistead of Virginia. Though he did not initially support the Republican policies of newly-elected President Abraham Lincoln, Hancock remained with the Union Army at the beginning of the Civil War as he felt that the Union should be preserved. Bidding goodbye to his southern friends as they left to join the Confederate Army, Hancock travelled east and initially was given quartermaster duties in Washington, DC. Winfield Scott Hancock - A Rising Star: This assignment was short-lived as he was promoted to brigadier general of volunteers on September 23, 1861. Assigned to the newly formed Army of the Potomac, he received command of a brigade in Brigadier General William F. Baldy Smiths division. Moving south in the spring of 1862, Hancock saw service during Major General George B. McClellans Peninsula Campaign. An aggressive and active commander, Hancock mounted a critical counterattack during the Battle of Williamsburg on May 5. Though McClellan failed to capitalize on Hancocks success, the Union commander informed Washington that Hancock was superb today. Seized upon by the press, this quote earned Hancock his nickname Hancock the Superb. After taking part in the Union defeats during the Seven Days Battles that summer, Hancock next saw action at the Battle of Antietam on September 17. Forced to take command of the division after the wounding Major General Israel B. Richardson, he oversaw some of the fighting along the Bloody Lane. Though his men wished to attack, Hancock held his position due to orders from McClellan. Promoted to major general on November 29, he led the First Division, II Corps against Maryes Heights at the Battle of Fredericksburg. Winfield Scott Hancock - At Gettysburg: The following spring, Hancocks division helped cover the withdrawal of the army after Major General Joseph Hookers defeat at the Battle of Chancellorsville. In the wake of the battle, the II Corps commander, Major General Darius Couch, left the army in protest of Hookers actions. As a result, Hancock was elevated to lead II Corps on May 22, 1863. Moving north with the army in pursuit of General Robert E. Lees Army of Northern Virginia, Hancock was called into action on July 1 with the opening of the Battle of Gettysburg. When Major General John Reynolds was killed early in the fighting, new army commander Major General George G. Meade sent Hancock ahead to Gettysburg to take command of the situation on the field. Arriving, he took control of Union forces after a brief squabble with the more senior Major General Oliver O. Howard. Asserting his orders from Meade, he made the decision to fight at Gettysburg and organized Union defenses around Cemetery Hill. Relieved by Meade that night, Hancocks II Corps assumed a position on Cemetery Ridge in the center of the Union line. The next day, with both Union flanks under attack, Hancock dispatched II Corps units to aid in the defense. On July 3, Hancocks position was the focus of Picketts Charge (Longstreets Assault). During the artillery bombardment that preceded the Confederate attack, Hancock brazenly rode along his lines encouraging his men. In the course of the subsequent attack, Hancock was wounded in the thigh and his good friend Lewis Armistead was mortally wounded when his brigade was turned back by II Corps. Bandaging the wound, Hancock remained on the field for the rest of the fighting. Winfield Scott Hancock - Later War: Though he largely recovered over the winter, the wound plagued him for the remainder of the conflict. Returning to the Army of the Potomac in the spring of 1864, he took part in Lieutenant General Ulysses S. Grants Overland Campaign seeing action at Wilderness, Spotsylvania, and Cold Harbor. Arriving at Petersburg in June, Hancock missed a key opportunity to take the city when he deferred to Baldy Smith, whose men had been fighting in the area all day, and did not immediately assault the Confederate lines. During the Siege of Petersburg, Hancocks men took part in numerous operations including fighting at Deep Bottom in late July. On August 25, he was beaten badly at Reams Station, but recovered to win the Battle of Boydton Plank Road in October. Plagued by his Gettysburg injury, Hancock was forced to give up field command the following month and moved through a series of ceremonial, recruiting, and administrative posts for the remainder of the war. Winfield Scott Hancock - Presidential Candidate: After supervising the execution of the Lincoln assassination conspirators in July 1865, Hancock briefly commanded US Army forces on the Plains before President Andrew Johnson directed him to oversee Reconstruction in the 5th Military District. As a Democrat, he followed a softer line in regard to the South than his Republican counterparts elevating his status in the party. With the election of Grant (a Republican) in 1868, Hancock was moved to the Department of Dakota and Department of the Atlantic in an effort to keep him away from the South. In 1880, Hancock was selected by the Democrats to run for president. Squaring off against James A. Garfield, he narrowly lost with the popular vote being the closest in history (4,454,416-4,444,952). Following the defeat, he returned to his military assignment. Hancock died at New York on February 9, 1886 and was buried at Montgomery Cemetery in near Norristown, PA.

Introduction to the Major Laws of Physics

Introduction to the Major Laws of Physics Over the years, one thing scientists have discovered is that nature is generally more complex than we give it credit for. The laws of physics are considered fundamental, although many of them refer to idealized or theoretical systems that are hard to replicate in the real world. Like other fields of science, new laws of physics build on or modify existing laws and theoretical research. Albert Einsteins  theory of relativity, which he developed in the early 1900s, builds on the theories first developed more than 200 years earlier by Sir Isaac Newton. Law of Universal Gravitation Sir  Isaac Newtons groundbreaking work in physics was first published in 1687 in his book The Mathematical Principles of Natural Philosophy, commonly known as The Principia. In it, he outlined theories about gravity and of motion. His physical law of gravity states that an object attracts another object in direct proportion to their combined mass and inversely related to the square of the distance between them. Three Laws of Motion Newtons  three laws of motion, also found in The Principia, govern how the motion of physical objects change. They define the fundamental relationship between the acceleration of an object and the forces acting upon it. First Rule: An object will remain at rest or in a  uniform state of motion unless that state is changed by an external force.  Second Rule:  Force  is  equal to the change in  momentum  (mass times velocity) over time. In other words, the rate of change is directly proportional to the amount of force applied.  Third Rule: For every action in nature there is an equal and opposite reaction.   Together, these three principles that Newton outlined form the basis of classical mechanics, which describes how bodies behave physically under the influence of outside forces. Conservation of Mass and Energy Albert Einstein introduced his famous equation E mc2 in a 1905 journal submission titled, On the Electrodynamics of Moving Bodies. The paper presented his theory of special relativity, based on two postulates: Principle of Relativity: The laws of physics are the same for all inertial reference frames.  Principle of Constancy of the Speed of Light: Light always propagates through a vacuum at a definite velocity, which is independent of the state of motion of the emitting body. The first principle simply says that the laws of physics apply equally to everyone in all situations. The second principle is the more important one. It stipulates that the  speed of light  in a vacuum is constant. Unlike all other forms of motion, it is not measured differently for observers in different inertial frames of reference. Laws of Thermodynamics The  laws of thermodynamics  are actually specific manifestations of the law of conservation of mass-energy as it relates to thermodynamic processes. The field was first explored in the 1650s by  Otto von Guericke  in Germany and  Robert Boyle  and  Robert Hooke  in Britain. All three scientists used vacuum pumps, which von Guericke pioneered, to study the principles of  pressure,  temperature, and  volume. The  Zeroeth Law of Thermodynamics  makes the notion of  temperature  possible.The  First Law of Thermodynamics  demonstrates the relationship between internal energy, added heat, and work within a system.The  Second Law of Thermodynamics  relates to the natural flow of heat within a  closed system.The  Third Law of Thermodynamics  states that it is impossible to create a  thermodynamic process  that is perfectly efficient. Electrostatic Laws Two laws of physics govern the relationship between electrically charged particles and their ability to create electrostatic force  and electrostatic fields.   Coulombs Law is named for Charles-Augustin Coulomb, a French researcher working in the 1700s. The force between two point charges is directly proportional to the magnitude of each charge and  inversely proportional to the square of the distance between their centers. If the objects have the same charge, positive or negative, they will repel each other. If they have opposite charges, they will attract each other.Gausss Law is named for  Carl Friedrich Gauss, a German mathematician  who worked in the early 19th century. This law states that  the net flow of an electric field through a closed surface is proportional to the enclosed electric charge. Gauss proposed similar laws relating to magnetism and electromagnetism as a whole. Beyond Basic Physics In the realm of relativity and quantum mechanics, scientists have found that these laws still apply, although their interpretation requires some refinement to be applied, resulting in fields such as quantum electronics and quantum gravity.

The management of financial risks in the telecom industry Essay

The management of financial risks in the telecom industry - Essay Example To study the financial risks of telecom industries, we will also introduce information regarding telecom sectors from countries such as India, China, and Philippines and so on to give an enhanced overview of existing practices. In this dissertation proposal, we will adequately sum up the reasons for this research, why it is significant, what methodology needs to be adopted, how information will be obtained and so on. As mentioned in the abstract, the purpose of this dissertation proposal is to study financial risk management in the existing telecom industry. Today, telecommunication is widespread and devices such as telephones, radios, internet, instant messaging and so on facilitate the process of communication. By definition, financial risk management means the process of identifying, evaluating and reducing financial risks. The telecommunication industry suffers from a number of problems such as market saturation2, financial recession, growing consumer prospects and so on. ... Moreover, certain external factors such as natural disasters and terrorist attacks, cross-border transactions, development of new markets and so on have added to the existing risks in the telecommunication industry paving the way for greater financial risk management. To gain a better perspective of financial risk management, let us consider some theories. Financial risk management3 becomes essential when an organisation desires an increase in its shareholders value by taking on a viable project. However, organisations alone, cannot hedge a risk correctly when the cost of the services or product is similar in the existing market and the market where the organisation desires expansion. For this purpose, these organisations require outside help in terms of financial risk management. Derivatives4 are commonly used in financial risk management as tools through which specific risks can be gauged effectively and accurately. Some of these derivativesi include swaps or forward contracts that tend to be costly; while others include trade on future exchanges that tend to be cost efficient but leave certain risks. Proposed methods As stated earlier, the purpose of this dissertation proposal is to study financial risk management in the existing telecom industry. In order to complete an efficient study of the project, the research will comprise of the following stages; a detailed literary search, anthology of a bibliography, drafting the literary review, designing the research instrument, revising, planning and organising the research, making a glossary of the bibliography, scheduling, conducting a research, collating and analysing the data generated by different agencies on a regular basis, writing the results and analysis, writing the full draft,
