Why Oil and Water Dont Mix

Why Oil and Water Dont Mix You may have experienced examples of how oil and water dont mix. Oil and vinegar salad dressing separate. Motor oil floats on top of the water in a puddle or in an oil spill. No matter how much you mix oil and water, they always separate. Chemicals that dont mix are said to be immiscible. The reason this happens is because of the chemical nature of oil and water molecules. Like Dissolves Like The saying in chemistry is that like dissolves like. What this means is the polar liquids (like water) dissolve in other polar liquids, while nonpolar liquids (usually organic molecules) mix well with each other. Each H2O or  water molecule is polar because it has a bent shape in which the negatively charged oxygen atom and the positively charged hydrogen atoms are on separate sides of the molecule. Water forms  hydrogen bonds between oxygen and hydrogen atoms of different water molecules. When water encounters nonpolar oil molecules, it sticks to itself rather than mingles with the organic molecules. Making Oil and Water Mix Chemistry has tricks for getting oil and water to interact. For example, detergent works by acting as emulsifiers and surfactants. The surfactants improve how well water can interact with a surface, while the emulsifiers help oil and water droplets mix together. Density and Immiscibility Oil floats on water because it is less dense or has lower specific gravity. The immiscibility of oil and water, however, is not related to the difference in density.

Future of technology (advantages and disadvantages) Essay Example for Free

Future of technology (advantages and disadvantages) Essay From day to day, our world has been changed gradually from one condition to another. Nowadays, technology has advanced in huge leaps and bounds. We cannot imagine the world without technological advances such as computer, televisions, and machines and so on. However there are some advantages and disadvantages of technology. First, technologies play an important role in society because it makes life easier to live on and makes time less consuming. People do not have to do all the hard labor anymore. For example, many people have washing machines, clothes driers and dishwashers, so the amount of energy needed to wash and dry clothes and wash dishes is greatly reduced. Second, medical science is very progressive and saves many innocent lives. Medical treatment has been going well with the help of technology. Nowadays, hospitals use technology as assistance for operations. However, technology also brings harm to our society. The overuse and development of factory industries causes pollution to our world. For example the use of cars and machines causes smoke that affects the quality of our air and destroys our ozone layer and as a result people suffer illnesses like cancer. Another disadvantage is that technologies create financial problems in families because most technologies are expensive. For example people that do not have a washing machine will have to wash clothes by hand which is time consuming. In conclusion, we cannot stop technology from developing in our society. Nowadays, we as people rely on technology everyday to make our lives simpler. Without modern technology our world would be a tough place to live in.

Influenza Fever :: Journalism Media Studies Ireland Health Essays

Influenza Fever DUBLIN, Ireland--It seems as though this year is not a good year for people as we have the big war going on and at home, people are stuck with a disease that the doctors do not know how to make it stop spreading. The epidemic has reached a boiling point as everyone is affected by this disease and it does not matter whether the person lives in Dublin, Ireland or Frankfurt, Germany, the disease still spreads. People dreaded to hear that they have been infected by that disease, they do not want to hear "influenza" is the disease that they are suffering from. Although the government has put out public notices that the disease is not infectious and tells people of ways to prevent as well as detect the disease, people are still afraid of it. They are in a state of panic as they are trying any means to protect themselves from having the disease. They are even gullible [enough] to believe that a certain type of nutrition tablet could help them to maintain vitality in their system so that [they] could effectively resist the influenza organism. Although, no one really knows how to cure the disease and certainly no one knows what makes one have it and one not, people are still flocking to the store to buy one of these so-called "nutrition tablets". However, this is not the worst case that I have seen since arriving at the infected city of Dublin as this latest trend will boggle anyone who has a sensible mind. A water company has advertised that people should not drink normal water because normal water has micro-organisms that will lead to influenza and only their brand of water is clean and pure and guaranteed to be free from any bacterial impurities. People are lining up at the store that I just passed by to buy the water from this company. Although I think that most of these advertisements about ways to not get influenza are scams, I cannot blame them for thinking that way. The influenza epidemic not only affected the children but also the economy as workers are infected by the disease. In a boot factory where before at lunch time one could see a bunch of girls and women come out taking their lunch break, the factory is now almost empty.

Homeostasis Essay

What is homeostasis? Homeostasis is the mechanism in our body that regulates and maintains a stable and constant environment. This enables our body to respond to changes in the environment around us as. The homeostatic mechanisms in our body, observe and monitor conditions and will then make a judgment whether to change the way the body functions is order to adapt to the outside surroundings better. The main organs involved in homeostasis are; the brain, liver, skin and kidney’s. The skin is involved as its acts as a protective layer and also regulates body temperature. The liver breaks down harmful substances and the kidneys regulate water levels and waste products. In the brain the hypothalamus controls everything and changing them to fit into the outside surroundings. Negative feedback is also linked in as it is the process of homeostasis. It is negative because it is in a negative situation and will not kick it unless there’s something wrong. Body temperature When we exercise the body has to work harder, the body temperature would increase this is due to organs having to work harder to get oxygen to muscles. The metabolic rate that produces more energy has to increase in order for more energy to be released. The heart has to pump more blood around the body in order to deliver oxygen to the working muscles so they can carry on working at that capacity. What mechanisms are there to cool the body down? Sweating-glands are stimulated to release sweat Liquid turn into gas Vasodilation-your body carries most of the heat energy around your body There are capillaries underneath your skin that can be filled with blood if you get too hot This brings the blood closer to the surface of the skin so more heat can be lost, this is why we look red when we’re hot. What mechanisms are there to warm the body up? Vasoconstriction-this is the opposite of vasodilation The capillaries underneath your skin get constricted (shut off) so less heat is lost Piloerection- this is when the hairs on your skin stand up The hairs trap a layer of air next to the skin which is then warmed by the body heat. Heart rate The heart rate is controlled by the autonomic nervous system. This system however, is split into two, the sympathetic nervous system and the parasympathetic system. The sympathetic system is in charge of speeding up the heart rate when it’s needed and the parasympathetic system is there to slow the heart rate down. There are many reasons why heart rate could increase; the main and obvious reasons are fear, stress and exercise. Exercise is one of the main reasons why heart rate would increase as when we exercise we need more oxygen to travel to our working muscles. Oxygen is only carried in the blood and the main organ for the blood pumping around the body is the heart. This is when the sympathetic nervous system comes in; the receptors tell the brain that we are doing exercise and then the brains sends a message to the heart to pump faster, in order for more oxygen to be transported in the blood to the working muscles. When we are not doing exercise we have a ‘pace maker ’ of the heart. This ‘pace maker’ called the Sino atrial node keeps a regular heart beat. We have tested our Sino atrial node by first of all doing exercise to see our risen heart rate, mine was 13. After 5 minutes of rest our Sino atrial node should have kicked in and our regular heart beat will be taking place, mine was now 11. The negative feedback system Change in the body’s external environment, the brain receives a message – exercise Change in body’s internal system Receptors detect change and send messages to the brain The brain organises internal and external body changes to bring the environment back to normal Breathing rate Breathing rate is determined by the amount of breaths taken during a certain  period of time. This can increase during exercise or any physical activity or trauma. The way in which the body recognises this is by the chemo-receptors. They send a message to the brain, which then sends a message to the heart to pump more blood by beating faster, this is because they have detected a change in the amount of carbon dioxide that is circulating the body. When the chemo-receptors detect a high level of carbon dioxide, they send a message to the brain to increase or decrease breathing rate in order to get rid of carbon dioxide or to replenish the amount of oxygen in the body. What happens next is very clever in the fact that the body recognises that during exercise we need more oxygen. Therefore messages in the form of nerve impulses are sent to the diaphragm causing it to contract. When the diaphragm contracts it lowers itself in order for the ribs to expand and move upwards so there is inc reased space for the lungs to inflate. The muscle that allows the ribs to move up and out is called the inter costal muscle. This process of breathing rate is called inspiration. When we exhale the reverse happens to what has just been explained. The diaphragm relaxes and returns to its original position. The inter costal muscle that allows the ribs to move up and out also relaxes and returns the ribs to their stationary position. This process is known as expiration. Blood glucose Blood glucose is simply the control of sugar levels in the body, and determines when the body needs more glucose (sugar) or when it needs less. The part of the body that controls the glucose is the pancreas. The pancreas releases insulin which is made to lower blood sugar levels when it gets too high but can also create glucagon that brings the blood sugar levels up when they are too low. Blood sugar levels mainly are affected and altered by the food we eat. Before a meal our blood sugar levels will be running low but after we’re eaten our blood sugar levels will be a lot higher, and in many cases will need the help of insulin to bring them down to the normal level, between 4 and 8ml, if we have consumed too much. The process of how we get the sugar is from the food we eat, mainly by the carbohydrates we consume. Carbohydrates are taken into the body by the food, and are then digested and changed into glucose that the body can use for energy. During exercise blood sugar levels will fall below our normal, so our body receptors say ‘level of glucose in the body is too low’ and therefore will tell the pancreas to produce glycogen to bring our sugar levels back up.

International Economics Gerber Study Questions Essay

The United States in a Global Economy 1.Outline Introduction Globalization in Perspective The Growth of World Trade Capital and Labor Mobility New Features of the Global Economy New Issues in International Trade and Investment The Role of International Organizations Regional Trade Agreements Trade and Economic Growth Twelve Issues in the International Economy The Gains from Trade Wages, Jobs, and Protection Trade Deficits Regional Trade Agreements The Resolution of Trade Conflicts The Role of International Institutions Exchange Rates and the Macroeconomy Financial Crises and the Global Contagion Capital Flows and the Debt of Developing Countries Crisis and Reform in Latin America Export Led Growth in East Asia The Integration of India and China into the World Economy 2. A Thumbnail Sketch of the Material Covered in Chapter One The re-emergence of international economic integration theme tries to put globalization in perspective. Most features of globalization aren’t new, and international economic integration could be described as re-emerging after a period of disruption during time periods surrounding WWI and WWII. There are three aspects of international economic integration considered: 1.The growth of world trade. World trade has grown over the last sixty or seventy years but is still fairly comparable in percentage terms to what existed 110 years ago. Trade has become a larger share of national economies as measured by the: Index of Openness (Exports Imports)/GDP This index does not tell us about a nation’s trade policies. Nations with higher figures for the index of openness do not necessarily have lower trade barriers. Large economies are less dependent on international trade and often have lower measures of openness than small countries. Figure 1.1 shows the openness index for six nations at different points in time. It shows the drop in trade from 1913 to 1950 and its growth (even above 1913 levels) for most nations by 2000. A trend obscured in the overall trade data is that in 1890 most U.S. trade was in agricultural products and raw materials, while today most is manufactured goods. The relative importance of capital goods has increased dramatically. 2.Capital and labor mobility. Labor is much less mobile internationally now than it was in 1900. For capital, it is somewhat more mobile. There is a difference between financial capital and physical capital. Foreign Direct Investment (FDI) is the flow of capital representing physical assets such as real estate, factories, and businesses. While capital flows to developing countries have increased over recent decades, the level of investment in any country is still correlated with its domestic level of savings, making national savings rates far more important than global capital flows. However, capital flows today are different from earlier periods in three ways. More types of financial instruments exist today, and flows of financial capital are likely much greater. In 1900, the world operated on a fixed exchange rate standard and much of today’s financial market transactions are aimed at protecting against exchange rate risk caused by floating exchange rates. Transactions costs associated with foreign capital flows have also fallen significantly. Volatility in international capital flows, while often a subject of intense attention today, is not new. 3.Movement of prices in different markets. The text does not develop this, but points out that in the late 1800s wheat farmers, meat packers, and fruit growers all produced for a global market where international rather than domestic supply and demand determined prices. News reports today could easily demonstrate this for most commodities. New issues in international trade and investment: Barriers to manufactured goods have fallen significantly as a result of a process that began at the end of WWII. As formal restrictions on imports  have been reduced, domestic policies on issues such as the environment, labor, and fair market conditions have become the barriers to further increases in trade flows. Reducing trade barriers has been the focus of negotiations between nations. Eliminating the traditional barriers to trade, tariffs and quotas, is referred to as shallow integration because it just changes policies â€Å"at the border.† Eliminating domestic policy differences that create trade barriers is much more complicated and is referred to as deep integration. International organizations created at the end of WWII play a key role and are an entirely new element in the international economy. Agreements between nations are not new, but there has been a significant increase in the number of regional trade agreements signed, especially in the 1990s. The formation of these regional trade agreements is controversial for different reasons for both trade opponents and trade proponents. The growth of world trade can potentially lead to a variety of consequences, but generally economists remain committed that the benefits outweigh the costs. This position is supported by the casual empirical evidence of historical experience, evidence supported by models and deductive reasoning, and evidence from statistical comparisons of countries. Open economies grow faster and prosper sooner than more closed ones. 3. What Students Should Know After Reading This Chapter Chapter 1 challenges the belief that the world has embarked on an entirely new and unprecedented era of globalization. Looked at from the long run, it seems clear that the period 1870 to 1914 was an earlier era with similar trends. Those years experienced rapid technological change in the form of railways, steamships, and telegraphs that all came into widespread usage and spanned the oceans; they underwent business and financial sector innovation through the rapid growth in the corporate form of business organization, the invention and spread of demand deposits, and the development of stockmarkets; trade policies were liberalized in many nations; and there were widespread protests against immigration and the global economy. In the United States, the protest movement was centered in populist movements that are reminiscent of some politicians and commentators today. This is not an argument about history repeating itself. Rather, i t is an attempt to get students to think of the period from World War I to the end of World War II as an aberration in the last 150 years of world history. The long run trend is toward  integration, punctuated by protests and nationalistic movements that halt or reverse the trend. When students are asked what they think is new about today’s economy, they inevitably answer: technology. E-mail, faxes, satellite systems, jet aircraft, and less visible forms such as container cargo transportation systems have each made significant contributions to increasing trade flows. It is useful to engage students in a discussion over the marginal impacts of these new technologies versus the marginal effects of steam powered ocean going vessels or trans-Atlantic telegraphy. Telegraphy cut the time it took information to cross the ocean from around three weeks to relatively instantaneously, and reduced the time it took to buy a foreign bond from around three weeks to about one day. It is us eful for students to realize there was a disruption for two reasons. First, much of what has happened over the last 50 years was aimed at fixing something that was broken, not creating a new phenomena. Second, the international institutions that deal with the global economy are new and were created because of some shared recognition that integration was important and helpful and needed to be encouraged. An important sub-theme of the text is the idea of deep versus shallow integration and the institutional process that nations go through to create deeper levels of integration. The chapter also points to some things that are new about today. Important ones for the text will be flexible exchange rates, regional trade agreements, and the changing mix of the types of goods nations produce. Domestic policies will be a key focus when trade barriers and capital flows are considered. Another important issue will be the evolving role of international organizations in negotiating and enforcing changes in domestic policies. 4. Assignment Ideas 1.I like to use the index of openness to contrast the importance of trade to various nations and to drive home the fact that relative value matters. The United States is a huge participant in trade in dollar terms, but it is not as dependent on trade as many other countries. Some countries’ entire economies are dependent on international trade. I find students need some practice calculating and interpreting the index of openness. The data below is from the World Fact Book and is 2006 estimated data in billions of U.S. dollars: Country Exports Imports GDP New Zealand 23.7 B 25.2 B 106 B Bahrain 12.6 B 9 B 17.7 B Brazil 138 B 95.8 B 1,616 B Cambodia 3.3 B 4.5 B 36.78 B Chad 4.34 B 0.823 B 15.26 B Nigeria 59 B 25.1 B 188.5 B 2. As homework very early in the course, I sometimes assign students each a nation, and one of the pieces of information they are to collect is its Index of Openness. I also ask them to find out its currency, current exchange rate with the U.S. dollar, primary exports, imports, major trading partners, and the trade agreements in which it participates. To compare with the U.S. historical data, you might ask them to track the nation’s trade figures over time. While these are basic matters of fact, I find it helps make what we are discussing more concrete. 3.The chapter also lends itself  to students developing some factual knowledge about U.S. trade history. One possibility is to look at U.S. trade policy in various time periods. The U.S. had relatively high tariffs (greater than 40 percent on average) throughout the second half of the nineteenth century. In 1890, Congress passed the McKinley Tariff, followed in 1897 by the Dingley Tariff. Both tariffs raised rates further fro m their already high base. Wilson tried to reduce tariffs but was thwarted by World War I. Rates in the 1920s fell, but the Tariff Act of 1930 (Smoot-Hawley Tariff) raised the rates back up to nearly 45 percent. In the midst of the Great Depression (1934), Roosevelt and his Secretary of State, Dulles, persuaded Congress to pass the Reciprocal Trade Agreement Act. The Act authorized Roosevelt to negotiate bilateral, reciprocal tariff reduction agreements. This piece of legislation marks an historic shift in U.S. tariff policy, away from protectionism and toward more openness. Answers to End-of-Chapter Questions 1.How can globalization and international economic integration be measured? Answer:The chapter offers three ways to measure globalization and economic integration: (1) trade flows; (2) factor movements; and (3) convergence of prices (goods, factors, and assets). 2.In what sense is the U.S. economy more integrated with the world today than it was a century ago? In what ways is it less integrated? Answer:The U.S.’s openness indicator is about sixty percent greater today than it was in 1890 ((25.3 – 15.8)/15.8 ï€ ½ 0.601), or almost one hundred and nine percent greater than in 1910. While this is a very significant increase, it is hardly the revolution in economic relations that many people claim. The sixty percent statistic might be considered misleading, however, in that a much larger share of total goods output is traded (more than thirty percent in 1990 versus less than ten percent in 1950). While we cannot compare the latter statistic to 1890 or 1900, it does appear that there is a clear trend toward a greater role for international commerce. This is consistent with the observation that world trade has been growing faster than world output, at least since 1950. Much of the growth in trade since then, however, simply brought us back to where we were before World War II. In terms of labor flows, the U.S. is probably less integrated with the world economy than it was in 1890 or 1900. At those latter dates we had an open door immigration policy (for all but Chinese citizens), and a larger share of our population was foreign born (fourteen and one half percent in 1890 versus less than eight percent in 1990 and twelve percent today). Capital flows are more difficult to generalize since they can be measured several ways. While the absolute volume of capital flows has increased dramatically, as a share of world GDP it is probably no more than it was at the turn of the century, and it may be less. While the absolute volume of capital flows to developing countries has increased, the level of investment in any country is still highly correlated with its domestic savings rate. What is different, however, is the ease at which capital can cross international boundaries (lower transaction costs) and the much greater variety of assets that are traded. The need to protect against exchange rate risk is a key component of today’s international financial markets and is a primary difference from the fixed exchange rate standard of the past. The incidence of financial crises has not increased and, as a metric of integration, it implies no increase in capital market integration. The growth of regional trade agreements is also an indicator of increased integration. A growing role for international institutions such as the IMF or the World Bank may also indicate an increase in international integration. 3.What is â€Å"openness†? How is it measured? Does a low openness indicator indicate that a country is closed to trade with the outside world? Answer:Openness is a measure of the relative importance of trade to a national economy. It is measured by the ratio of exports plus imports to GDP. A relatively small openness indicator does not necessarily mean that an economy is intentionally closed to the outside world. Large countries like the U.S. or China have big domestic markets that enable firms to specialize and produce in volume in order to attain their optimal scale. Specialization and high volume in manufacturing is often associated with increased productivity, so firms in large markets can achieve the highest possible level of productivity without having to sell to foreign markets. Firms  located in smaller countries have to trade their output across international boundaries if they want to have the same technology and the same level of productivity. Consequently, large countries tend to have lower openness indicators regardless of their trade policies. 4.Describe the pattern over the last century shown by the openness index for leading industrial economies. Answer:The indicators fell between 1913 and 1950, when it begins to rise relatively rapidly. The main caus es of the pattern shown in Figure 1.1 are the two world wars and the Great Depression of the 1930s and changes in trade policy that accompanied that period. In 2000, they are mostly higher than they were before WWI. Another pattern the chapter notes is that the index is smaller for the larger population countries of Japan and the United States, and higher for the Netherlands, with its small population. 5.Trade and capital flows were described and measured in relative terms rather than absolute. Explain the difference. Which term seems more valid, relative or absolute? Why? Answer:Absolute values are the dollar amounts of trade and capital flows. Relative values are the ratio of dollar values to GDP. Relative values are a better indicator of the importance of a variable. Large economies like the U.S. may have large export and import values, but the importance of trade to the national economy is not nearly as great as it is for other economies. The U.S. is the world’s largest e xporter and importer, but the national economy is so large that trade is much less important for the U.S. than it is for many smaller countries such as Canada, Belgium, or the Netherlands. 6.The relative size of international capital flows may not be much greater today than they were 100 years ago, although they are certainly greater than they were 50 years ago. Qualitatively, however, capital flows are different today. Explain. Answer:Major qualitative difference between late nineteenth and late twentieth century capital flows include the fact that there are many more types of financial instruments available now compared to a century ago. These instruments can be finely tailored to the income and risk preferences of investors. Secondly, a large share of the total flow of capital across borders is related to the need to protect against fluctuations in the value of currencies. This use of international capital markets was not as necessary when nations operated within fixed exchange r ate systems. And third, the transaction costs of participating in international capital markets is much lower today than it was a century ago. 7.What are the new issues in international trade and investment? In what sense do they expose national economies to outside influences? Answer:The new issues involve policy differences between nations that until recently were considered the exclusive responsibility of local or national governments. Examples include labor standards, environmental standards, competition or antitrust policies, and industrial support policies. Negotiations between nations potentially give foreign interests a voice in setting domestic policy. The scope and the depth of the negotiations determine how great a voice foreigners will have. It is often the case, however, that negotiations either occur or are proposed because some aspect of domestic policy is perceived by foreigners as a barrier to trade, and they seek to alter the domestic policy that creates it. 8.Describe the three kinds of evidence economists use to support the assertion that open economies grow faster than economies that are closed to the word economy. Answer:These are: (1) casual empirical evidence of historical experience; (2) economic logic and deductive reasoning; and, (3) evidence of statistical comparisons of countries. (1)The historical evidence examines the experiences of countries that tried to isolate themselves from the rest of the world. First, not only did trade protection exacerbate the depression of the 1930s, but it also led to the misery and tragedy of World War II. Second, an examination of countries such as the former West and East Germany, South and North Korea, and other countries with the same historical, economic, and ethnic background that were divided by war, indicate that those who closed their economies from the rest of the world suffered in terms of prosperity and environmental degradation. East Asia experienced an economic take-off when it dec ided to integrate with the rest of the world, while Latin America, which had the same economic background with East Asia but chose to remain partially closed, experienced mediocre growth. (2)The logic of economic theory also suggests a strong causal relation between trade and faster economic growth. The following is a summary of this linkage: Following Adam Smith, David Ricardo proved that comparative advantage leads to trade and this in turn leads to the reallocation of resources and the improvement of the standard of living of any nation, large or small. Modern trade theory also makes the case for exports and open trade as the causes for economic expansion. Exports and open trade foster competition, innovation, and learning-by-doing, and bring international best practices to the attention of domestic producers, spurring greater efficiency and export expansion. This helps domestic producers to realize economies of scale when they attempt to produce for the world market, rather than for their own limited domestic consumers. Larger markets create incentives for firms to engage in research and development, and allow countries to import important production inputs and foreign capital by minimizing the foreign exchange constraints. They facilitate the transfer of technology and managerial skills. It follows that open trade an d exports increase the demand for the country’s output and therefore contribute strongly to positive economic growth. (3)Even though the statistical evidence is not quite conclusive (mainly due to measuring trade policy), the evidence of statistical comparison of countries (cross-sectional time series) indicates that countries benefit from open trade.

Martin Luther King Jr Quotes

Martin Luther King Jr Quotes Dr. Martin Luther King, Jr. (1929-1968) was a principal leader of the non-violent Civil Rights Movement in the U.S. He not only began the Civil Rights Movement with the Montgomery Bus Boycott, he became an icon for the entire movement. Since King was, in part, famous for his oratory abilities, one can both be inspired and learn much by reading through these quotes by Martin Luther King, Jr. "Letter From Birmingham Jail," 16 April 1963 Injustice anywhere is a threat to justice everywhere. We will have to repent in this generation not merely for the hateful words and actions of the bad people but for the appalling silence of the good people. Freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed. I submit that an individual who breaks a law that conscience tells him is unjust, and willingly accepts the penalty by staying in jail in order to arouse the conscience of the community over its injustice, is, in reality, expressing the very highest respect for the law. We who engage in nonviolent direct action are not the creators of tension. We merely bring to the surface the hidden tension that is already alive. Shallow understanding from people of good will is more frustrating than absolute misunderstanding from people of ill will. We were here before the mighty words of the Declaration of Independence were etched across the pages of history. Our forebears labored without wages. They made cotton king. And yet out of a bottomless vitality, they continued to thrive and develop. If the cruelties of slavery could not stop us, the opposition we now face will surely fail... Because the goal of America is freedom, abused and scorned tho we may be, our destiny is tied up with Americas destiny. "I Have a Dream" Speech, August 28, 1963 I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. When we let freedom ring, when we let it ring from every tenement and every hamlet, from every state and every city, we will be able to speed up that day when all of Gods children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of the old spiritual, Free at last, free at last. Thank God Almighty, we are free at last. "Strength to Love" (1963) The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy. The true neighbor will risk his position, his prestige and even his life for the welfare of others. Nothing in all the world is more dangerous than sincere ignorance and conscientious stupidity. The means by which we live have outdistanced the ends for which we live. Our scientific power has outrun our spiritual power. We have guided missiles and misguided men. A nation or civilization that continues to produce soft-minded men purchases its own spiritual death on an installment plan. "I've Been to the Mountaintop" Speech, April 3, 1968 (the day before his assassination) Like anybody, I would like to live a long life. Longevity has its place. But Im not concerned about that now. I just want to do Gods will. And hes allowed me to go up to the mountain. And Ive looked over, and Ive seen the promised land . . . So Im happy tonight. Im not worried about anything. Im not fearing any man. Nobel Prize Acceptance Speech, December 10, 1964 I believe that unarmed truth and unconditional love will have the final word in reality. This is why right temporarily defeated is stronger than evil triumphant. "Where Do We Go From Here?" Speech, August 16, 1967 Discrimination is a hellhound that gnaws at Negroes in every waking moment of their lives to remind them that the lie of their inferiority is accepted as truth in the society dominating them. Other Speeches and Quotations We must learn to live together as brothers or perish together as fools. - Speech in St. Louis, Missouri, March 22, 1964. If a man hasnt discovered something he will die for, he isnt fit to live. - Speech in Detroit, Michigan on June 23, 1963. It may be true that the law cannot make a man love me, but it can keep him from lynching me, and I think thats pretty important. - Quoted in The Wall Street Journal, Nov. 13, 1962.

This is called duplication anomalies. It also ensures that the database has consistency (Date, 2006). The most important thing about normalization is that it allows the user to perform all types of queries which out errors. 1st Normal Formal Form (CategoryNum , Category Description ServiceID , SlipID, Description, CategoryNum, Status, EstHours ,SpentHours ,NextServiceDate). This is table in the first normal form. It has already been normalized from the 0nf because it has a primary key(Date, 2006). The table is in the first normal form (NF1) because it contains no repeating attributes or group of attributes. 2nd Normal Formal Form (CategoryNum , CategoryDescription ServiceID , SlipID, CategoryNum, Status, EstHours ,SpentHours ,NextServiceDate). This table is in second normal form because it is in first normal form and has no partial key dependency. It also means that there is no column that is not part of a primary key is dependent on only portion of the primary key.
