Kyle Upham, a soldier who was about to be deployed on his second tour of duty in Iraq, was in the store with his wife, Kristen. He wanted to upgrade her ring to something nicer. One engagement set caught Kristens eye, but it was $9,000 way out of their budget. I noticed there was someone else in there, but didnt give it much thought, Kristen recalled to CBS in Los Angeles. We started looking at rings and whatnot and he kept saying, Go bigger and I kept saying, No, look at the prices. The newlyweds struck up a conversation with Walker and soon realized they were speaking to the star of The Fast and the Furious actor. Walker seemed even more impressed with Kyles line of work. After there conversation the couple left the store without purchasing anything. While heading out the salesperson ran out of the store calling the couple back stating that the 9000$ ring is freee of charge.

He called the manager and he said, Um, the ring that those people are looking at put it on my tab,' she said. Soon after that, he just left. To do something like that to a perfect stranger is just unbelievable, King adds. The couple, who is still happily married, plans to hand the ring down to the next generations in their family.

Free Essays on Alexander The Great Why hello. Thank you for taking an interest in my life, as you already know I am Alexander the great. You’re probably wondering why I have such a cool nickname as â€Å"the Great† huh? Well, stick around and listen to what I have to say about myself and then you can be the judge on whether or not I should be known as Alexander the Great, or Alexander the Best. Sorry, just a little joke. Obviously I can’t give you a life story day by day, so here’s my life in a nutshell. The miraculous year that I was born was 356 B.C. That makes me (pretty damn old) 2,358 years young. I was born into royalty in Pella, Macedonia, being my father was King Philip II, and my mother Queen Olympias. As most of you already know all great figures want the best for their children, so for my education I was tutored by Aristotle; one of the greatest minds to ever live. Since I was heir to the thrown I supported and backed my father 100%. I fought many campaigns for my father, but after I let my temper loose one time I was sent into exile with a few of my companions. I returned after the death of my father in 336 B.C., in which Darius had believed to be involved in, and was hailed as king, although I was careful to eliminate any possible rivals to the throne. This started the path to becoming â€Å"the Great.† I had to clean up so to speak, what my father had already started and undertook the invasion of Asia. Now with me as the â€Å"commander-in-chief† my first goal was to restore a sense of stability back to the League of Cornith (the League of Cornith was a league formed of Greek city-states, held together by treaties and alliances) that was starting to break apart. I felt it was my job to prove myself to my followers, townspeople, and most of all my father. I began by executing all potential enemies of Philip in court. My father would have been so proud of me for that (sniffle, sniffle). My next mission was to regain support of all ... Free Essays on Alexander the Great Alexander the Great, was born in June, 356 BC, in Pella, the ancient capital of Macedonia. His parents were Philip II and Olympia. Some say that Zeus was his father but it is probably just a myth. Aristotle taught Alexander in his early teen years. He stimulated his interest in science, medicine, and philosophy. In the summer of 336 BC, Alexander's father was assassinated, and Alexander ascended to the Macedonian throne. He found himself surrounded by enemies at home and threatened by civilizations all over. But Alexander disposed of quickly of all his enemies by ordering their execution. Then he took off to Thessaly, where partisans of independence had gained ascendancy, and restored Macedonian rule. Before the end of the summer of 336 BC as general of the Greeks in a campaign against the Persians, originally planned by his father before he croaked, he carried out a successful campaign against the defecting Thracians, penetrating to the Danube River. On his return he crushed in a single week the threatening Illyrians and then again took of to Thebes, which had revolted. He took the city by storm and razed it, sparing only the temples of the gods and the house of the Greed lyric poet Pindar, and selling the surviving inhabi ¬ tants, about 8000 in number, into slavery. Alexander's promptness in crushing the revolt of The ¬ bes brought the other Greek states into instant submission. Alexander began his war against Persia in the spring of 334 BC by crossing the Hellespont (now Dardanelles) with an army of 35,000 Macedonian and Greek troops: his chief officers, all Macedonians, included Antigonus, Ptolemy, and Seleucus. At the river Granicus, near the ancient city of Troy, he attacked an army of Persians and Greek soldiers which totaled 40,000 men. His forces slatured the enemy and according to tradition, only lost 110 men! After this battle all the stated of Asia Minor submitted to Alexander. Continuing south,... Free Essays on Alexander The Great Alexander the Great was a great military leader for many reasons. His life was filled with events that would provide him with valuable experience. The people with whom he was close while growing up urged him to try his hardest, and this also contributed to his great leadership. In the following paper, I will explain how Alexander’s parents and education, among other things, helped him to gain the necessary experience and qualities of a good leader, and how he used this experience as he got older and became a greater military leader. Alexander’s youth played a great role in his development into a great military leader. Many aspects of his youth contributed to this development, including his parents, his education, and the military experience he had early on in his life. Alexandros was born in the summer of 356 BC to Philip II and Olympias (â€Å"Alexander the Great† 1). Alexander’s parents both wanted him to become a great leader, both pushing him to do his best. When Alexander was young, his mother, Olympias, poisoned Philip’s other son so that he could not compete with Alexander. She also once commanded Cleopatra to commit suicide, and then threw Cleopatra’s infant son into a fire (Roselle 28). Alexander received not only support from his mother, but probably inherited her hot temper. One of the men who played the greatest role in Alexander’s life was his father, Philip II. As Alexander was growing up, Philip always treated him like an adult, and Alexander in turn treated him with respect (Gunther 8). This bond between father and son was never broken, although it was weakened by one event. When Alexander was a teenager, his father and he got into an argument, and Alexander then ran away from home. Alexander soon returned, and although he and his father made peace, he never actually forgave his father (â€Å"Alexander the Eckert 2 Great† 1). There was one other man who affected Alexander’s life near ly as much as Philip did. ... Free Essays on Alexander the Great Voltaire quickly chose literature as a career. Advertisement He began moving in aristocratic circles and soon became known in Paris salons as a brilliant and sarcastic wit. A number of his writings, particularly a lampoon accusing the French regent Philippe II, duc d'Orlà ©ans of heinous crimes, resulted in his imprisonment in the Bastille. During his 11-month detention, Voltaire completed his first tragedy, Å’dipe, which was based upon the Å’dipus tyrannus of the ancient Greek dramatist Sophocles, and commenced an epic poem on Henry IV of France. Å’dipe was given its initial performance at the Thà ©Ãƒ ¢tre-Franà §ais in 1718 and received with great enthusiasm. The work on Henry IV was printed anonymously in Geneva under the title of Poà ¨me de la ligue (Poem of the League, 1723). In his first philosophical poem, Le pour et le contre (For and Against), Voltaire gave eloquent expression to both his anti-Christian views auuuuuuuuuuuuuuuuuuucreed. A quarrel with a member of an illustrious French family, the chevalier de Rohan, resulted in Voltaire's second incarceration in the Bastille, from which he was released within two weeks on his promise to quit France and proceed to England. Accordingly he spent about two years in London. Voltaire soon mastered the English language, and in order to prepare the British public for an enlarged edition of his Poà ¨me de la ligue, he wrote in English two remarkable essays, one on epic poetry and the other on the history of civil wars in France. For a few years the Catholic, autocratic French government prevented the publication of the enlarged edition of Poà ¨me de la ligue, which was retitled La Henriade (The Henriad). The government finally allowed the poem to be published in 1728. This work, an eloquent defense of religious toleration, achieved an almost unprecedented success, not only in Voltaire's native France but throughout all of the continent of Europe as well. III. Popularity at CourtP... Free Essays on Alexander The Great Alexander the Great was king of the Macedonians and one of the greatest generals in history. Alexander was born in 356 as the son of the Macedonian king Philip II (359-336). Alexander the Great was born in 356 B.C. His father, Philip, was the brother of King Perdiccas III of Macedon or Macedonia, in northern Greece. His mother was Philip's wife Olympias, daughter of King Neoptolemus I of Epirus, in modern Albania. Alexander had a younger sister, Cleopatra (not the famous Egyptian queen). Unfortunately for Alexander and Cleopatra, their parents hated each other. In keeping with Macedonian tradition, Philip had several lesser wives, and Olympias regarded these other women and their children with great animosity. When one of her rivals gave birth to a retarded son, Philip Arridaeus, it was rumored that Olympias had caused his disability with poison. Olympias told Alexander that Philip wasn't his real father, but this probably wasn't true. Philip certainly seems to have believed that Ale xander was his son. He made sure the boy was well educated; the great philosopher Aristotle was one of Alexander's tutors. At the age of 13, Aristotle was hired to be Alexander’s private tutor. Aristotle inspired interests of politics, other races of people and countries, plants and animals, and a great love for literature in Alexander. He was an outstanding athlete and excelled in every sport of his time. In 338 B.C., at the age of 18, Alexander led the cavalry of his father’s army in the Battle of Chaeronea, which brought Greece under Macedonian control. At the age of 20, Alexander’s father was murdered by one of his bodyguards, and Alexander succeeded the throne as king of Macedonia. After his father's murder in 336 B.C. Alexander became King Alexander III. After Alexander’s father died, some Greek cities under Macedonian rule revolted. In 335 B.C., He had several rival claimants to the throne executed, including his cousin Amyntas, whose t... Free Essays on Alexander the Great Alexander the Great By: Lynn E-mail: moninghoff@yhoo.com Who is â€Å"Great†? In history there are few people who can be termed â€Å"Great† and even fewer who deserve to be called so. Alexander, the son of King Phillip of the Macedonians, was one of these truly â€Å"Great† people. He not merely ruled the largest know empire, was declared a God, lead his troops in battle, and conquered foreign cities, his first being at the age of sixteen, but he did it all within a thirteen year time period. Not only did he do all of this, but also it was done within thirteen years. When Alexander became the new King of Macedonia, many believed him to be to young to rule. They felt that he didn’t have the experience needed to be their new leader. They had no way of knowing of the many things that he would come to accomplish in such a short time period. Alexander’s first great accomplishment occurred when he was just sixteen years old. At this time, his father went away to war leaving Alexander to serve as a regent of Ma cedon. During his father’s absence, Alexander led an expedition to a wild region that is now known as modern day Bulgaria. Once there, he subdued the rebellious barbarians and established his first city, Alexandropolis. On the return from his trip, King Philip was so impressed by his son’s achievement that he appointed him a general in the royal army. (www.mrdowlings.com) When Alexander turned his attack towards Persia, his forces were much smaller than his opponent’s. Alexander’s army conquered Persia anyway, by winning a series of battles in which his troops were better trained and organized than the Persian army. His soldiers also admired Alexander because of his personal participation in the battles. He led his soldiers into battle instead of remaining behind the lines as was common for military leaders to do at that time. This allowed the troops to see that Alexander was sharing their danger, and was not asking the... Free Essays on Alexander The Great Alexander the Great, Hybris – Nemesis Life In the life of Alexander the Great, one could examine that he had a hybris-nemesis effect on the world. As a great conqueror and warrior Alexander resembled the mind a hyberistic man that created a nemesis world view in his Hellistic world. Throughout his life time one can evaluate that Alexander had a great unchecked pride that was never tested till the gods took his soul. We can also see that because of his hybris view that he could only create a world of nemesis all around him, just like that of the man that he chased all throughout his crusades of Persia the King of Kings, Dorias who may have been his greatest adversary. It is without a doubt Alexander the Great definitely lead a Hybris lifestyle that led to a Nemesis world view like the other conquerors before him. As stated by John Porter, â€Å" hybris is a tricky word. Today it is used to refer to â€Å" overweening pride,† often in very Christian terms. In antiquity, however, hybris was a form of violent arrogance or aggression that displayed itself, not in one’s attitudes, but in one’s actions.† This is exactly what Alexander the Great resembled both in life and the battlefield. When in battle Alexander would rush into battle, weather he outnumbered the enemy or the enemy outnumbered him, with battened disregard for the safety of his men or himself. In the Battle of Issus in 333 B.C. Alexander and his men charge through Dorias’ Persian army directly at Dorias, who in fear retreats and abandons his family and army. Dorias’ army discuses the battle and his family is captured and kept as Alexander’s personal servants. In these actions Alexander resembles the meaning of a â€Å"hybristic man,† as also defined by John Porter â€Å"was n ot simply a proud or arrogant man (as we have seen, the Greeks did not regard justifiable pride as a character flaw) but treated others with violence that suggested that they were in effect mere... Free Essays on Alexander the Great Alexander the Great was the king of Macedonia, conqueror of the Persian Empire, and one of the greatest military leaders of all times. Even at an early age, Alexander showed that he would a great leader. Through all his victories and conquests, he has become a great hero and has had a large impact on history. Alexander, born in 356 B.C. in Pella, the ancient capital of Macedonia, was the son of Philip II, king of Macedonia. Alexander's tutor, Aristotle, taught him from age 13 to 16 in medicine, science, and philosophy. When the time came, he was well prepared to take over the throne. In the summer of 336 B.C. Philip was assassinated, and Alexander became the new ruler of Macedonia. He soon showed his power when the large city of Thebes revolted in 335. He charged the city with mighty force and took 30,000 people as slaves. Alexander’s next attempt was to defeat Persia because he could never be the dominant force in Europe as long as the Persian ruler Darius was still living. A fter beating Persia the second and final time in 332, Darius, who managed to survive, fled to the mountains. He died in the mountains when one of his own men killed him. With Darius dead, Alexander was crowned King of Persia and became known as the king of all Asia. Babylon surrendered after Gaugamela, and the city of Susa was soon conquered. In midwinter, Alexander forced his way to Persepolis, the Persian capital. After plundering the city of its treasuries and taking other rich â€Å"booty†, however he burned the city during a drunken rage, which completed the destruction of the ancient Persian Empire. His empire now extended along and beyond the southern shores of the Caspian Sea, including modern Afghanistan and Baluchistan, and northward into Bactria and Sogdiana, the modern Western Turkistan, which is also Central Asia. It had taken Alexander only three years, from the spring of 330 B.C. to the spring of 327 B.C., to gain control of this vast empire. In or... Free Essays on Alexander The Great â€Å"Alexander the Great: Hunting For A New Past?† Paul Cartledge attempts to tell the history of the myth and legend of Alexander the Great in this article. Alexander was born to Olympias and Philip of Macedon, or was he, in 356 at the Macedonian capital of Pella. Olympias claims that Alexander was conceived not by Philip, but by the Egyptian God Amun. So the legend begins. As a teenager Alexander is said to have tamed a fiery and exorbitantly expensive Thessalian stallion called Bucephalas. This was Alexander’s horse for hunting and war. Bucephalas and Alexander were unfortunately separated when the steed died in Pakistan at the age of thirty. Alexander loved his horse so much that he named a city after him. At the age of sixteen Alexander was appointed regent of Macedon while his father was away on a campaign. To upstage his father, Alexander waged war on the Thracian people and established a new capital named after, of course, himself. To become a man though Alexander had not to conquer a city, but to hunt and kill a wild boar and a human enemy. This allowed him the right to recline at social gatherings rather than sit straight up. It is said that alcohol may have played a factor in Alexander the Great’s early death. Some scientists say that he may have become a clinical alcoholic. This cannot be proven today, but according to Cartledge his drinking habit may have led him to kill his personal companion and senior cavalry commander. Alexander was taught by Aristotle, the greatest intellectual of his time. Aristotle advised Alexander to treat all non-Greeks as barbarians. He obviously did not pay much attention to this because of his many wives were of non-Greek people. Despite all his wives it is said that Alexander may have had interest in the opposite sex. How they can prove this I am not sure, but the author wrote that he may have had at least two lovers of the opposite sex. One was a boyhood fri...

Discuss the issue of legalization of marijuana Essay

Discuss the issue of legalization of marijuana - Essay Example Marijuana has always been a controversial drug, but it has become even more so since individual states have petitioned for its legalization for medical purposes. Though the long-term goal is to legalize the drug for recreational purposes, the short-term goal is to get it approved for medical uses. Some states, such as California, have opened up medical marijuana dispensaries, which allow people with prescriptions to obtain their drugs. They were able to be approved for medical marijuana because they provided proof that it is the only drug that can ease nausea and chronic pain. Doctors, scientists, and government officials alike believe that as long as the drug is being used for its intended purpose, then it should be legalized as a medical drug. Unfortunately, not all patients are using marijuana as directed. Since quite a few patients are able to grow their own medical marijuana, some have abused the system and have sold marijuana to be used as a recreational drug. While marijuana has shown its usefulness in helping some of the sickest patients, they are not helping society by making an illegal and controversial drug more readily available to the public. On the other side of the coin in regard to marijuana is legalization for recreational purposes. Many individuals from a variety of backgrounds have tried to compare marijuana with alcohol and cigarettes, attempting to convince those in power that marijuana is no worse than these other vices. Indeed, people have proven that marijuana is actually the lesser of the three evils (Regan 109). As such, it is believed that as long as marijuana is treated and regulated like alcohol and cigarettes, then there should be no reason for the drug to remain illegal. One of the assumed perks of legalized marijuana for recreational purposes is that drug-related crime will significantly decrease. This is due to the belief that if marijuana is legal, people will not have

Introduction to Requirements and Systems Modelling Essay

Introduction to Requirements and Systems Modelling - Essay Example Post Conditions The LED keep on showing the updated status of the water level received from the sensors. Assumptions It is assumed that the user has switched on the button of the Tunze Osmolator and checking / viewing LED to know the level of the water. Basic Flow: 1. The user of the Tunze Osmolator switches on the machine. 2. The sensor motor activates itself and detects levels of the water in the tank. 3. The sensor sends the information to the arithmetic unit to compare the sensor’s value with the lower set value of the tank. 4. Once the value has been compared, the LED would show the information whether the water level is lower than the threshold value [A – 1]. 5. The motor starts itself to increase the level of the water till it reaches to the upper limit of the tank. Alternate Flow: A – 1. The motor would not start if the water level in the tank is higher than the required or lower threshold value of the tank. Conditions Trigging Alternate Flow: The alterna te flow would only be initiated if the water level in the tank is within the prescribed threshold limits. Note: - The use case description format has been taken from the book of the R. S. Pressman. Unified Modeling Language (UML) In software engineering, the Unified Modeling Language (UML) is a standardized modeling language that facilitates to create a graphical depiction of the object oriented systems under development. The UML is utilized for specifying, building, visualizing and documenting the software artifacts for the software application is to be developed. The UML adopts a combination of various concepts including the Booch, Object Modeling Technique (OMT) and Object Oriented Software Engineering (OOSE). By utilizing these concepts the UML provides a single platform for describing and modeling the software systems. However, there are various limitations of the UML, as it focuses on software rather than hardware (Overgaard, Selic and Bock, 2000). In other words, there are ma ny issues in building the UML of the real-time systems include: the description of hardware elements, time constraints, communications tasks and network modeling. Many solutions have been developed to overcome these issues and one of the solutions is to build the diagrams in three (3) tier structure of the system. In the first tier the object building and software construction would focus on the software architecture, whereas, the system architecture would focus on the hardware and communications aspects of the system (Lou, 2000). The Tunze Osmolator water level controller system relates to the systems based on hardware more as compared to the software implementation. As described above, therefore, it can be stated that the implementation of the UML notation is quite difficult for the systems entirely based on hardware, time constraints and communications tasks. As the Tunze Osmolator includes the hardware and communications tasks, therefore, comparatively the UML notation cannot be as fruitful as for the data-intensive applications or the software applications mostly based on the software. On the other hand, the UML notation can effectively use in various software engineering areas include but are not limited to the enterprise resource planning, banking and accounting services, web based

The length and width Essay Example for Free

The length and width Essay This is due to the electron s for a long distance than before. Thus we say the resistance increases. When the width of the wire increases, the hindrance for the flow of electrons increases. Because the space through which electrons flow increases. Thus we say that the resistance decreases Preliminary Width of the wire ( mm) Length of wire (mm) Voltage (V) Current (A) Resistance ( ? ). From this preliminary experiment I will increase the length of the wire up to 30cm in order to get the reliable results. The reason why I chose the thin wire is because to get a high resistance and therefore it is easy to measure. I have used three different widths because I want to find out width gives the best results. To get precise measurement I will measure the value of the current and voltage up to two decimal places. Obtaining evidence This is how the set up of my apparatus looks like. First I join everything together and check if everything is in the right place. Then I adjust the 30cm length of wire to the length of 5cm, 10cm, 15cm, 20cm and 25cm, with the help of the crocodile clip. After that I change the resistance by means of the variable resister to get an accurate measurement /result of the current and voltage for each length. Actual experiment Width of the wire ( mm) Length of wire (mm) Voltage (V) Current (A) Resistance ( ? ) Safety When the experiment has been started the wire becomes hot. The safety here is to put the things (e. g. paper, books, exercise books etc. which are inflammable) to a side, so that it cannot come into contact with the wire. After finishing the experiment turn the current off. Length (cm) Average Resistance   I can use the results not with 100% certainty; I can rely only on 60%. This is in regard to change in resistance caused by the charge on the length of the wire. This is in regard to the change in resistance caused by the change in length of the wire. As far as concerning the change in resistance due to change the width of the wire are anomalous. Analysis My experiment shows longer the wire higher the resistance. That is, when the length of the wire increases, resistance increases. Resistance is directly proportional to the length of the wire. Resistance of wire ? length of the wire Resistance = k x length Observation K Constant First 0. 21/5 0. 04 Second 0. 45/10 0. 04 Third 0. 58/15 0. 04 Fourth 0. 87/20 0. 04 Fifth 0. 95/25 0. 04 From the above table, this numerical calculations shows that the resistance is directly proportional to the length of the wire. If I double the length of the wire, the resistance also get doubled as a result. My experiment ,in respect of the conductor with the length of 15cm, shows that the current flow is directly proportional to the potential difference. The voltage ? current In respect of other length of the conductors (5cm, 10cm, 15cm, 20cm and 25cm) there is a variation in the second decimal of the constant figure. These discrepancies may be due to the slight changes of the external temperature of the conductor when current passes through the conductors. It may be also due to the reading of the ammeter and voltmeter by the eye. Evaluation My results are reasonably good as far as concerning the change of resistance due to the change in length of the conductor. My results are fairly good as far as concerning the Ohms law. That is, the current passes through the conductor is directly proportional to the potential difference across the conductor provided the temperature remains constant. My results were not at all good as far as concerning changes of the resistance due to changes in the width of the conductor. My graph which shows the resistance and length of the conductor is a straight line which passes through the origin and 3 points. Two points stays out of the line. For the variation of the resistant, I could not draw one line on one graph and I have drawn 5 lines on one graph. I could not draw my conclusion on the graph because the variations of the width are not great enough to produce significant variation in the resistance. Only 2 points fell on the line and the third one slipped out. If the straight line passes through 3 points on the graph we can depend on the reliability (length against resistance graph). In contrast in the width against resistance graph, only 2 points falls on the straight line. Therefore I cannot depend on the reliability. This anomaly is due to the fact that the wires which I have chosen are not considerably vary in thickness (width). Another way of doing that is to take reading using the constantan wire and then the second reading connecting 2 wires as shown in the prediction and keep on doing this for 3, 4 wires. The anomalous points on the graph (2 points) may be due to the crocodile clips which were not properly attached. There may be lack of specification in observing the ammeter and voltmeter with the eye. There may be fluctuation in the external and in the internal temperature of the conductor. I can use a conductor made of nichrome which is an alloy of 60% nickel, 24% iron and 16% chromium. Accurate laboratory standard are made from a coil of resistance wire inside a protective plastic case. 1 Show preview only The above preview is unformatted text This student written piece of work is one of many that can be found in our GCSE Electricity and Magnetism section.

General Information Deoxyribonucleic acid (DNA) which is found in all living thing and one of the building blocks of the body. (1, 2, 3) The molecule is found in the nucleus of the cell and it is a double helix molecule and it looks like a twisted ladder. If it was unwound the molecule would be 6 feet in length! (2) DNA has 3 nucleotides which are sugar, base, and phosphate. (1) The four bases, which are adenine (A), thymine (T), cytosine(C), and guanine (G) and they are all Nitrogen bases and there are about 3 billion of them.(1, 2, 3, 4) Adenine and thymine always pair up with one another and cytosine and guanine always pair together. (1, 2, 3, 4) In the cell there is also the RNA which acts as the messenger for the DNA because the DNA is too big to leave the nucleus. (1) RNA also doesn’t have thymine, instead it has uracil. (1, 2, 3, 4) The RNA then goes off to tell the ribosomes to make protein for parts of your body that need it the most. (1) Genes are the heredity material that is made up by DNA. (1, 2, 3) Your genes are all have from your mother and half from your father. (2) All of your genes are inside chromosomes which carry your genes. (2, 3, 4) The chromosomes carry thousands of your genes and your DNA will replicate your genes so it stays the same. (1, 2, 3, 4) If the gene code is changed it will cause a mutation. Some mutations can be good like evolution, but some can cause cancer. (1, 2, 3, 4) The 4 different types of mutation are point, frame shift, deletion, and insertion. (1, 2, 3, 4) Point and Frame shift are not as bad because it’s just changing a letter in a sequence but, insertion and deletion are changing the whole sequence.

American life Essay

Who says grabbers are only for narratives? Some of the best expository pieces start out with sentences that capture the readers’ attention. The authors from different literary genres give their own attention grabbers to make their pieces more attractive and more suspense from the beginning up to the end. According to Ruhanie Perera (2007), â€Å"Each creator brings with them their values and beliefs shaped by their education and exposure to English Literature, but their search is the same – for the creative, the bold, the sharp and the fresh. † However, expository grabbers are not created only for narratives but for all kinds of situations like in the field of soccer. Deep down in the ocean lurks a dangerous killing machine. This is one of the examples that we hear in soccer. It is a form of attention grabber to make the players become aware of their actions. From this aspect, it only means that any attention grabber must be new from the ears, minds, and eyes of the audience. Many of us like soccer. We watch different plays and games on television about soccer. This is somehow part of American life. Because of this, we hear different attention grabbers from the announcers, coaches, and players. When these people say their expository grabber, the crowd yells and feels that there is hope for success. Like narratives, attentions grabbers could be heard in the beginning of the event. Expository grabbers make each situation noble and powerful. In soccer, attention grabber means a lot of things – it becomes the life and endurance of the team to work hard and win the game. That is why even in this field, expository grabber is very important. In conclusion to this, it can be said that expository grabbers lift the minds and hearts of the audience or readers. It gives power and indirect control to the spectators. The people may not realize this but they were influenced in freedom and captivation.
