Social Anxiety And The Classroom Essay - 862 Words

I didn’t know what to expect. It had been years since I’d last sat in a classroom with forty other kids my age. What if I’m not as smart as them? What if I make a fool of myself? Thoughts like these swarmed around my head as I watched the clouds roll by my mom’s. Surely I was smart enough; after all, I did get accepted into the same program as all the other kids. The Young Scholars Program, an opportunity like no other. This program offered at Sinclair would grant you a two-year scholarship; all you had to do was dedicate your Saturdays from 8th-grade year to senior year. I was overcome with social anxiety, I had gone to school since the fourth grade, and I preferred homeschool over the classroom setting. Yet, here I was about to start the journey that would affect the rest of my life. I made my way to Sinclair’s basement alone, attempting to navigate where the classroom was. Everything looked the same, the carpet remained the same muddy brown, the walls the same blaring white, the fluorescent lights occasionally flickering eerily. The atmosphere alone was enough to send me into a panic. As I neared closer to my room I began to feel like I was suffocating. The room began to spin. I can’t do this. I can’t do this. I can’t do this! The thought as resounding. I had to push through, but it seemed impossible. The hall began to fill with other kids my age; I knew I was just about there. With one last final breath, I emerged into the lecture hall. The room was huge.

Looming Economic Crisis in United States Free Essays

On January 21st and 22nd 2008, world financial markets crashed amidst the fears of American economy slowly are gradually moving toward recession. The emerging markets world over corrected almost 20 to 30 percent while the developed financial markets of Europe and American corrected over 10-15 percent. At present the DOW is 20 percent below its July top a signal that financial markets are entering a bear phase. We will write a custom essay sample on Looming Economic Crisis in United States or any similar topic only for you Order Now (Landler Timmons 2008) The paper will try to shed light on what is looming large on American economy, what are the policy or market failures which are taking the economy into recession, How the present Bush plan of stimulus will impact the scenario in future and will it be good enough to bring the economy back on track. Main contributors to the slowdown of the economy American economy is hit by numerous factors at the same time – growth slowdown, increasing unemployment numbers, falling retail sales, increasing trade deficit, weakness of dollars, emergence of Euro, housing crisis and failure of financial markets. (Landler Timmons 2008) Housing Market – The housing market has been slowing down for an year now and most presidential candidates are suggesting ways on how American economy can come out this mess. The slowdown in the housing market is due to high default rate on mortgages especially sub-prime mortgages. During the credit expansion time post first Bush tax cuts banks and financial institutions lowered their vigilance on credit rating and in quest to expand market end up giving housing mortgages to shady borrowers. Another reason why this happened was – money was easy to come and housing market was on uptrend so in case of failure of installment and foreclosure the banks and financial institutes were able to get the money back through increased price of the houses. But after the slowing down of housing markets real estate rates have fallen 5-10 percent in last year only and according to UBS it is expected go down by 15-20 percent more in coming year. Increasing National Debt – the present national debt is around 9 trillion dollars which accounts for almost 65 percent of the Gross Domestic Product. Such high level of national debt increases the interests on payments significantly and reduces the elbow space of the government in tinkering with the fiscal policy. In the past America able to finance its debt by weakening the dollar but now with emergence of Euro it has become increasing difficult to export the national debt to foreign institutions and countries which in past are happy to maintain huge dollar reserves. (Kjeldsen, 2002) Increasing Trade Deficit – The profitability of American companies have grown over the past half a decade but the trade deficit hasn’t come down. The main reason for it is off-shoring and outsourcing. American companies are making the most of low cost manufacturing and services in countries like China and India to boost their bottomline. Low level of saving rates – In response to the main reason for credit card default rate one women respondent on CNBC summed up the saving rate of Americans – â€Å"we all like to buy things, we all love to travel and we don’t want to wait for it†. This culture of plastic money spending today paying later has brought down saving rates to alarming levels and it can significantly hamper the investment in the economy. Increasing inequality among Americans – the last tax cuts provided immense benefits to the rich Americans and increased the income gap between the rich nation and poor nation. Hurricane Katrina exposed the underbelly of this growing inequality in the country and it will take years of corrective actions. Financial Markets crash – America is financial market sensitive country by that it means that the wealth effect among American can be reflected by the state of the financial markets as more than 80 percent of the population invest in the financial markets. This has let the consumer sentiments down which is resulting in lowering retail sales and subsequently lowering employment generation. (Landler Timmons 2008) President Bush Stimulus Plan President Bush has passed the stimulus plan of 168 billion into law, the stimulus plan will ensure money in the hand of real consumers in short time which will help in keeping the economy afloat by not letting the demand go drastically down. In the long run along with the tax cuts and stimulus plan the economy will able to get new investments which can bolster production and employment opportunities. The stimulus package will start providing tax cuts after May and before that it provide a one time rebate of 600 dollars for the individual and 1200 for couple and an additional 300 dollar each for a child in the family.   (MSNBC, 2008) The stimulus plan may be a step in right direction but the challenges the economy is facing are fundamental one. With high oil prices and fears of inflation the tax cuts may end up fuelling the inflation in the economy resulting in more import of cheap products from countries like China which is maintaining fixed exchange rates. Conclusion At present the economy is looking down the barrel and there is a very slim chance that it will escape recession and more importantly a growth slowing down in next 2-3 years. America is fast graying and productivity going down with increasing health costs, the times seems to be certainly tough in future. The one ray of hope is creating of jobs by investing in new technologies which America is historically good at. References Kjeldsen-Kragh, Soeren. (2002)   International Economics.

Rutherfords Gold Foil Experiment Essay Example For Students

Rutherfords Gold Foil Experiment Essay Rutherfords Gold Foil ExperimentRutherford started his scientific career with much success in local schoolsleading to a scholarship to Nelson College. After achieving more academichonors at Nelson College, Rutherford moved on to Cambridge UniversitysCavendish laboratory. There he was lead by his mentor J.J. Thomson convincedhim to study radiation. By 1889 Rutherford was ready to earn a living andsought a job. With Thomsons recommendation McGill University in Montrealaccepted him as a professor of chemistry. Upon performing many experiments andfinding new discoveries at McGill university, Rutherford was rewarded the nobelprize for chemistry. In 1907 he succeded Arthur Schuster at the University ofManchester. He began persuing alpha particles in 1908. With the help of Geigerhe found the number of alpha particles emitted per second by a gram of radium. He was also able to confirm that alpha particles cause a faint but discreteflash when striking luminescent zinc sulfide screen. These greataccomplishments are all overshadowed by Rutherfords famous Gold Foil experimentwhich revolutionized the atomic model. This experiment was Rutherfords most notable achievement. It not onlydisproved Thomsons atomic model but also paved the way for such discoveries asthe atomic bomb and nuclear power. The atomic model he concluded after thefindings of his Gold Foil experiment have yet to be disproven. The followingparagraphs will explain the significance of the Gold Foil Experiment as well ashow the experiment contradicted Thomsons atomis model. Rutherford began his experiment with the philosophy of trying any damfool experiment on the chance it might work.1 With this in mind he set out todisprove the current atomic model. In 1909 he and his partner, Geiger, decidedErnest Marsden, a student of the University of Manchester, was ready for a realresearch project.2 This experiments apparatus consisted of Polonium in a leadbox emitting alpha particles towards a gold foil. The foil was surrounded by aluminescent zinc sulfide screen to detect where the alpha particles went aftercontacting the gold atoms. Because of Thomsons atomic model this experimentdid not seem worthwhile for it predicted all the alpha particles would gostraight through the foil. Despite however unlikely it may have seemed for thealpha particles to bounce off the gold atoms, they did. Leaving Rutherford tosay, It was almost as incredible as if you fired a fifteen-inch shell at apiece of tissue paper and it came back and hit you. Soon he came up with a newatomic model based on the results of this experiment. Nevertheless his findingsand the new atomic model was mainly ignored by the scientific community at thetime. In spite of the views of other scientists, Rutherfords 1911 atomicmodel was backed by scientific proof of his Gold Foil Experiment. When heapproched the experiment he respected and agreed with J.J. Thomsons, his friendand mentor, atomic theory. This theory proposed that the electrons where evenlydistributed throughout an atom. Since an alpha paritcle is 8,000 times as heavyas an electron, one electron could not deflect an alpha particle at an obtuseangle. Applying Thomsons model, a passing particle could not hit more than oneelctron at a time; therefore, all of the alpha particles should have passedstraight through the gold foil. This was not the case a notable few alphaparticles reflected of the gold atoms back towards the polonium. Hence the massof an atom must be condessed in consentrated core. Otherwise the mass of thealpha particles would be greated than any part of an atom they hit. AsRutherford put it:The alpha projectile changed course in a single encounter with a target atom . But for this to occur, the forces of electrical repulsion had to be concentrated in a region of 10-13cm whereas the atom was known to measure 10-8cm.He went on to say that this meant most of the atom was empty space with a smalldense core. Rutherford pondered for much time before anouncing in 1911 that hehad made a new atomic modelthis one with a condensed core (which he named thenucleus) and electrons orbitting this core. As stated earlier, this newatomic model was not opposed but originally ignored by most of the scientificcommunity. .u909f7f9544d1284c57e5d572d2c2d02f , .u909f7f9544d1284c57e5d572d2c2d02f .postImageUrl , .u909f7f9544d1284c57e5d572d2c2d02f .centered-text-area { min-height: 80px; position: relative; } .u909f7f9544d1284c57e5d572d2c2d02f , .u909f7f9544d1284c57e5d572d2c2d02f:hover , .u909f7f9544d1284c57e5d572d2c2d02f:visited , .u909f7f9544d1284c57e5d572d2c2d02f:active { border:0!important; } .u909f7f9544d1284c57e5d572d2c2d02f .clearfix:after { content: ""; display: table; clear: both; } .u909f7f9544d1284c57e5d572d2c2d02f { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u909f7f9544d1284c57e5d572d2c2d02f:active , .u909f7f9544d1284c57e5d572d2c2d02f:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u909f7f9544d1284c57e5d572d2c2d02f .centered-text-area { width: 100%; position: relative ; } .u909f7f9544d1284c57e5d572d2c2d02f .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u909f7f9544d1284c57e5d572d2c2d02f .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u909f7f9544d1284c57e5d572d2c2d02f .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u909f7f9544d1284c57e5d572d2c2d02f:hover .ctaButton { background-color: #34495E!important; } .u909f7f9544d1284c57e5d572d2c2d02f .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u909f7f9544d1284c57e5d572d2c2d02f .u909f7f9544d1284c57e5d572d2c2d02f-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u909f7f9544d1284c57e5d572d2c2d02f:after { content: ""; display: block; clear: both; } READ: Gettysburg Address EssayRutherfords experiment shows how scientists must never just accept thecurrent theroies and models but rather they must constently be put to new testsand experiments.
