If I Were George Bush Essay example -- essays research papers

If I Was George Bush   Ã‚  Ã‚  Ã‚  Ã‚  If I was George Bush I would follow the exact same path he is following right now. His plans for our countries Education and Health Care plan live up to their promises. These plans also benefit the country greatly as a whole. Yet, if I was President Bush, I would make the positive effects of these plans to prove themselves more immediate than they have been. This would urge America to follow my, or Bush’s, plans to make America a better place.  Ã‚  Ã‚  Ã‚  Ã‚   The Education Plan the Bush has produced is almost perfect. It contains six key points that I totally agree with. The first part of the plan says that American will provide state grants to recruit and train teachers. The second part of the plan being that America will be recruiting high quality Individuals to become teachers. The third part says that America will be expanding programs to train teachers in specific subject areas. The fourth part suggests that America will implement the Teachers Protection Act. The fifth part says that a new teacher’s tax deduction will be implemented. Lastly, the sixth part of the plan says that America will be providing expanded student loan forgiveness for teachers. All of these goals lead to one key plan. This plan is to put a quality teacher in every room. If this feat can be accomplished, I would follow the exact same plan Bush is following right now. Bush basically has this plan covere...

The Assassin Strikes Again

Once there lived a man named Jack. Every day he woke up refreshed and renewed. Jack started the day by having a nice big stretch, and then he did 100 press-ups. He took a cold shower and brushed his teeth with Sensodyne Jack dressed him self in casual clothes and left for work. Jack has a usual profession. He is hired by rich and powerful people to murder the innocent and honest. Jack became an assassin when he was a teenager. During his childhood he had been kind, generous and helpful boy. One day he was walking home with his friends. Jack's friends suggested that they should go through the alley because it was a shortcut home. Jack agreed and so did the others. They walked through the dark, deep and frightening alley, then they saw a gang of bullies in the alley but they decided not to run. It was a bad decision. The biggest bully started straight away on Jack's smallest friend Mark. Jack consumed with anger, picked up a iron bar and whacked it down violently on the bully's head â€Å"Ahhhh† Jack yelled ferociously, the bullies terrified ran away as fast as they could Jack kept on hitting and hitting the bully until he could not move a muscle. His shocked friends knew he had killed him. They ran way in different directions. The police arrived. Jack ran as fast as he could, until he was out of breath, Even now he's still running and running away from the Police. News travelled fast and within months rich and powerful people were begging Jack to kill their enemies. During a few years Jack was responsible for 15 deaths of innocent people. He was there offered one million pounds to murderer a man called Tom Matthews by his former friend Reece Jones. Tom and Reece had been best friends. Tom was a kind, generous and an intelligent man. Tom had a beautiful wife names Angela. They had just got married three months ago; Tom had joined Reece's company shortly before. Every day he dressed in a black suit and went off early in the morning to work. He was on time every day and ready to go. Tom had a poor family back ground and was determined to make best of his chances. Reece had a wealthy back ground and was always wasting money on gambling. He was always late for work, Reece was very jealous of Tom. One day Tom got promoted to Assistant Manager, Reece was so furious he said â€Å"that's it! I will have Tom murdered!† When he finished work, he rushed home to call an assassin and arranged a meeting outside an abandoned house. He gave Tom's details and his picture to Jack. Reece paid à ¯Ã‚ ¿Ã‚ ½100, 000 in advance the rest to follow when the job was done. Jack researched Tom's lifestyle carefully and worked out when Tom would be alone. It was when he went through the junk yard as a shortcut to his home. Jack planned the murder methodically. He would use a rifle with a silencer to shoot him. On May 17th 2004 the plan took action. First he would pretend he was being attacked by a vicious gang He would run up to Tom and beg for his help and say â€Å"I am being attacked by a vicious gang who are trying to murder me.† Tom was driving on the way home from work, feeling tired and sleepy when he was driving through the junk yard, a man rushed in front of his car, Tom stepped as hard as he could on the brake Tom stormed out of his car and asked mysterious man â€Å"Are you Ok† the strange man replied â€Å"no I am not I am being chased by a vicious gang who want to murder me†. The stranger wore a black leather coat and a woollen knitted scarf covering him from the misty fog and cold. The man told Tom he was delivering a package and was shocked when he saw a gang of teenagers brutally murdering an innocent man. Tom went a few steps ahead to see whether he could locate the gang. Jack took out his rifle from his right coat pocket and pointed it at when Tom looked at Jack with astonishment and a fear of death, Jack shot Tom with no hesitation or any mercy the bullet tore through the muscles as it went for the heart of Tom. Tom could see the blood was red As a red paint. Tom could see the blood on Jacks shoes as he fell on to the ground as he was falling he repeatedly asked â€Å"why†, â€Å"why† When he fell on to the ground there was silence. Jack made Tom's murder seem like an accident he put Tom into the car and drove Tom off the cliff. The next day Jack received the full payment from Reece. As Jack was reading the news paper, he saw that Tom's death made the front page. Seeing Tom's wife's picture made him realise that Tom's wife was the girl he loved when he was in school. After thinking for several hours he came up with the decision that he should surrender to the police. The next day he stood in front of the police station thinking should I surrender to the police or not.

Starburst Galaxies

The universe is filled with galaxies, which are themselves filled with stars. At some point in its life, each galaxy bristled with star formation in vast clouds of hydrogen gas. Even today, some galaxies seem to have more than the usual amount of star birth activity and astronomers want to know why. There were so many stars being born in some galaxies in earlier times that they probably looked like cosmic fireworks bursts. Astronomers refer to these hotbeds of star birth as starburst galaxies. Key Takeaways: Starburst Galaxies Starburst galaxies are galaxies where high rates of star formation has occurred very quickly.Nearly all types of galaxies can undergo starburst events if conditions are right.Astronomers know that starburst galaxies are often involved in mergers that mingle stars and gas. Shock waves push the gas, which sets off the starburst activity. Starburst galaxies have unusually high  rates of star formation, and those bursts last for a short time during the galaxys long life. Thats because star formation burns through the gas reserves of the galaxy very quickly. It is likely that the sudden burst of star birth is triggered by a specific event. In most cases, a galaxy merger does the trick. Thats when two or more galaxies mesh together in a long gravitational dance and eventually meld together. During the merger, the gases of all the galaxies involved are mixed together. The collision sends shock waves through those gas clouds, which compress the gases and set off bursts of star formation.   Properties of Starburst Galaxies Starburst galaxies are not a  new type of galaxy, but rather simply a galaxy (or mingled galaxies) in a particular phase of their evolution. Even so, there are some properties that show up in most starburst galaxies: a very rapid star formation rate. These galaxies will produce stars at rates well above the average rate of most regular galaxies; availability of gas and dust. Some galaxies may have higher than normal star-formation rates simply due to their high volumes of gas and dust. However, some starburst galaxies do not a have the reserves to justify why they would have such high rates of star formation, so mergers may not be the only explanation;star formation rate is inconsistent with the age of the galaxy. The main point is that the current rate of star formation could not have been constant since the formation of the galaxy given its age. An older galaxy simply wouldnt have enough gas left over to keep up starbirth action for billions of years. In some starburst galaxies astronomers see a sudden burst of star birth, and often the explanation is a merger or chance encounter with another galaxy. Astronomers sometimes also compare the rate of star formation in a galaxy relative to its rotational period. If, for example, the galaxy exhausts all of its available gas during one rotation of the galaxy (given the high star formation rate), then it can be considered a starburst galaxy. The Milky Way rotates once every 220 million years; some galaxies go much slower, others faster. Another widely accepted method to see if a galaxy is a starburst is to compare the star formation rate against the age of the universe. If the current rate would exhaust all of the available gas in less time than 13.7 billion years, then its possible that a given galaxy may be in a starburst state.   Annotated image showing dazzling eyelid-like features bursting with stars in galaxy IC 2163.

ALMA image of carbon monoxide (orange), which revealed motion of the gas in these features, is shown on top of Hubble image (blue) of the galaxy. M. Kaufman; B. Saxton (NRAO/AUI/NSF); ALMA (ESO/NAOJ/NRAO); NASA/ESA Hubble Space Telescope Types of Starburst Galaxies Starburst activity can occur in galaxies ranging from spirals to irregulars. Astronomers who study these objects classify them into sub-types that help describe their ages and other characteristics. Starburst galaxy types include: Wolf-Rayet galaxies:  defined by their ratio of bright stars that fall into the Wolf-Rayet classification. Galaxies of this type have regions of high stellar wind, driven by the Wolf-Rayet stars. Those stellar monsters are incredibly massive and luminous and have very high rates of mass loss. The winds that they produce can collide with regions of gas and drive rapid star formation.Blue compact galaxies:  low mass galaxies that were once thought to be young galaxies, just beginning to form stars. However, they usually contain populations of very old stars. That usually is a good clue that the galaxy is quite old. Astronomers now suspect that blue compact galaxies are actually the result of mergers between galaxies of varying ages. Once they collide, starburst activity ramps up and lights up the galaxies.Luminous infrared galaxies:  dim, hidden galaxies that are difficult to study because they contain high levels of dust that can obscure observation. Typically infrared radiation   detected by telescopes is used to penetrate the dust. That provides clues to increased star formation. Some of these objects have been found to contain multiple supermassive black holes, which can shut down star formation. The increase in star birth in such galaxies has to be the result of a recent galaxy merger. Cause of Increased Star Formation Although the merger of galaxies is pinpointed as the main cause of star birth in these galaxies, the exact processes are not well understood. Partially, this is due to the fact that starburst galaxies come in many shapes and sizes, so there may be more than one condition that leads to increased star formation. However, for a starburst galaxy to even form, there must be lots of gas available to generate the new stars. Also, something must disturb the gas, to begin the gravitational collapse process that leads to the creation of new objects. Those two requirements led astronomers to suspect galaxy mergers and shock waves as two processes that can lead to starburst galaxies.   Centaurus A galaxy has a massive black hole at its heart that is actively gobbling up material. The actions of such active galactic nuclei may play a role in starbursts in galaxies.   ESO/WFI (Optical); MPIfR/ESO/APEX/A.Weiss et al. (Submillimetre); NASA/CXC/CfA/R.Kraft et al. (X-ray) Two other possibilities for the cause of starburst galaxies include: Active Galactic Nuclei (AGN): Virtually all galaxies contain a supermassive black hole in their core. Some galaxies appear to be in a state of high activity, where the central black hole is ejecting massive amounts of energy.  There is a great deal of evidence to show that the presence of such a black hole can dampen star formation activity. However, in the case of these so-called active  galactic nuclei, they can also, under the right conditions, trigger rapid star formation as the accretion of matter in a disk and its eventual ejection away from the black hole can create shockwaves that could trigger star formation.High supernova rates: Supernovae are violent events. If the rate of explosions increases due to the presence of a very high number of aging stars in a compact area, the resulting shockwaves can begin a rapid increase in star formation. However, this such an event to occur the conditions would have to be ideal; more so than in the other possibilities listed here. A supernova can push clouds of nearby gas around spur limited amounts of starbirth. This supernova is shown in a Hubble Space Telescope view of the Crab Nebula supernova remnant. NASA/ESA/STScI Starburst galaxies remain an active area of investigation by astronomers. The more they find, the better scientists can describe the actual conditions that lead up to the bright bursts of star formation that populate these galaxies.   Edited and updated by Carolyn Collins Petersen.
