The Search for Quark :: essays research papers

What exactly is Quark? Quark: a fermion which is believed to be one of the fundamental constituents of matter. All quarks have a fractional electric charge1. This pretty much means quarks have  ½ spin (rotate two full rotations to get to place it started), apply to Pauli Exclusion Principle, is one of the things that make up all matter, and its electric charge is a fraction. There are three different colors of quark; red, green, and blue. The colors always up to white. Also there are three different kinds of antiquark; cyan, yellow, and magenta. Quarks are at least 330MeV. Quarks were first proposed in 1964. It was named quark by Caltech theorist Murray Gell-Mann. He named them that from a quotation in a novel â€Å"Three quarks for Muster Mark, Sure he hasn’t got much of a bark †¦Ã¢â‚¬ 2 Gell-Mann said all mesons, baryons, and hadrons are made of quarks. He also said they are made of three types of quarks (up, down, and strange). That makes a total of nine types of quarks. George Zweig called them aces. Not many people believed in it at this time. From 1968 to 1973 MIT bombarded protons and neutrons with electrons. Electrons ricocheted off protons and neutrons as if it hit a hard, tiny object. The hard object was a quark. Over the years experiments and researches have led to a lot of indirect evidence that quarks exist. Despite all this indirect evidence they could not find a single free quark. No particle detector detected one. This led to a lot of non believers. As more proof has been shown that quarks exist it became more popular and less doubted. Chapter 1: Over coming Skepticism   Ã‚  Ã‚  Ã‚  Ã‚  Doubters did not believe in quarks. They thought of quarks just as a math equation that could explain a couple of things. They had good reason. The quark was never found free or even revealed itself. That was until 1974 when two discoveries occurred at the Brookhaven Laboratory and Stanford. They had found a new particle. Stanford called it the psi and Brookhaven called it the J. The new particle had to be a new kind of quark. Two years later Harvard theorist Sheldon Glashow named the new particle the charmed quark. This discovery shattered any doubts about the quark being real or not.   Ã‚  Ã‚  Ã‚  Ã‚   The discovery also shattered the bootstrap model theory. This theory said that protons, neutrons, and other particles were the smallest units.

Walden Theme

I believe that the overall message or theme of the novel Walden was to be simplistic. In his section â€Å"Economy† he stated that the feeling of dissatisfaction with one's possessions can be fixed In two ways; one might require more to fulfill the emptiness, or one might reduce their desires to achieve satisfaction. I think that this Is a true statement because you don't need everything In life to be happy. You could have the bare necessities and live your life with the same Joy as someone that Is successful and needs everything expensive to make them happy.It is all about your perspective on how you want to live your life. Another example that went along with the theme of simplicity was when he talked about other residents that were going through life Just trying to make mortgages and payment to all the new things that they own and still wanting the newest fashion trend. On the other hand Thoreau decided that he wanted to live his life differently he took another path that w as indeed the simple life. He left society and lived in the woods to live this certain lifestyle.If he ever came long a time that he needed new clothes, he Just patched them instead of getting the latest fashion and he only wanted the necessary accessories. He thought If you bought something that wasn't needed to survive everyday life was Just a disadvantage of living life to Its fullest. Think of the last time you went shopping for groceries. Did you Just buy what you needed or did you buy other things that you could live without? Do you really need that pack of gum to survive?Most likely you didn't need that pack of gum, cigarettes or zebra cakes. You could just buy what you absolutely need and still live. This is what Walden wanted most people to see is that you can live a simple life with only the necessities and be happy with how you have fulfilled your life. To live this simple life Thoreau built his own shack and actually owned it instead of having a house that was owned by a bank because of a mortgage. Because he didn't have all the big payments he was able to afford other things that he needed.He did say that those that have larger, more Impressive possessions actually have less when you compare them to his possessions. They might have a nice car but he has his life and all that It contains and doesn't have to worry about others taking It away because they can't pay for it. The last thing that I would like to say about the theme simplicity, is that he definitely lived a very simple life but he didn't do the same for his writing style. Thoreau writing in this book was complicated and filled with quotes, puns and double meanings that were not at all simple.He wrote this book in such a way that it was a little hard to read and understand the point he was trying to get across, but we ere able to accomplish it and at least understand a little bit of it. Overall, since I think that the theme of this book was to be simplistic I think that Thoreau achieved hi s goal in living a simple life and making his life be filled to the fullest. I also think that If he were still alive today and had the chance to see how many people are still reading his novel that he would be surprised. I bet he didn't think that his book was going to be as successful as It Is.Thoreau lived his life the way that he wanted and it was to be as simple as it could be. In his section â€Å"Economy' he stated that the feeling of dissatisfaction with one's possessions can be fixed in two ways; one might require more to fulfill the emptiness, or one might reduce their desires to achieve satisfaction. I think that this is a true statement because you don't need everything in life to be happy. You could have the bare necessities and live your life with the same Joy as someone that is successful latest fashion and he only wanted the necessary accessories.He thought if you bought something that wasn't needed to survive everyday life was Just a equidistant of living life to i ts fullest.

Fullest. I also think that if he were still alive today and had the chance to see how think that his book was going to be as successful as it is. Thoreau lived his life the

Remember the Titans Essay

In â€Å"Remember the Titans† there are at least a series of ten or more conflicts, whether they are physical, mental, interpersonal, or even just random violence. there are groups of whites on one side and blacks on another side, having an interpersonal conflict about the school becoming integrated. A white boy gets an attack of random violence and he is killed, causing a group of white football players, deciding split second, create an assailant against a group of black people; thinking that if some blacks decide to do random violence on a white person that it is ok for them to create an act of aggravated assault on the blacks. As football camp comes rolling around, many of the whites still separate themselves from the blacks and vice versa. Coach Boone steps in to be a mediator and to have many of the kids converse with each other so they can learn tolerance with each other, causing less want for homicide. This causes any other conflicts to not escalate and then everyone is heard out on what they want to say or have to say. There is a conflict of authority between Coaches Yoast and Boone. Then there is a budding friendship between Bertier and Julius, and then the team in general uniting together regardless of color. The successful, almost-hall-of-famer, white coach, Bill Yoast is suddenly replaced by a no-crap-taking black coach, Herman Boone. At first there is a power struggle between Coach Boone and Coach Yoast, Coach Boone wants to run things his way and Coach Yoast wants to keep different things the way they were. They soon begin to level with each other and work together as a unit which is good for the team. In the beginning of the film Bertier was like the leader of the white boys of his team and Julius is seemingly the head of the black kids. When they arrive to football camp, the first day they fight. Julius doesn’t like the way Bertier leads the team as a captain and he decides that he is going to look out for himself, when Bertier brings up the fact this attitude is not good for the team Julius questions him as to why he is letting the black kds do the brunt of the work. Bertier realizes that Julius is right and then starts to change first off by correcting his white best friend’s blocking. Thus begins their friendship. When they get back from the camp they face problems in school from being friends. When Julius helps bertier stop a fight he gets called an â€Å"Uncle Tom†. When Bertier turnd down his girlfriend to go hang out with Julius she tells him that he needs to get his priorites straight. But through all this they remain best friends.

Appearance vs. Reality in Sedgwicks Hope Leslie

Appearance vs. Reality in Sedgwicks Hope Leslie In her novel, Hope Leslie, Catharine Maria Sedgwick supplants the importance of strict adherence to religious tenets with the significance the human conscience and following one's own heart. This central theme of the novel is intimated to the reader in the scene where Sir Philip Gardiner, a character that completely defies this ideal, is described. Although he "had a certain erect and gallant bearing that marks a man of the world . . . his dress was strictly puritanical" (124). In other words, even though his demeanor is completely unlike that of a puritan, he adheres to the outward seeming of one. The scene describes in detail these markings and intimations of his person that would indicate an attitude not befitting a puritan. His face suggested the "ravages of the passions" while his constantly roving eyes indicated a "restless mind" (124). The only signs of Sir Philip's "puritanism" are his pretenses and his clothing, and these are enough to convince society he is a religious man, quite a "dandy quaker" (125).English: The actress Leslie Hope at San Diego Comi...Sir Philip is hailed as "a godly and approved member of the congregation" (152). He is considered such an exemplar of the puritanical faith that he is deemed a more appropriate match for Hope than Everell. While Sir Philip maintains the outward appearances of a puritan, Everell, while his "puritan principles [remain] uncorrupted . . . has little of the outward man of a 'pilgrim indeed'" (150). When Mr. Fletcher asks Winthrop about the validity of Sir Philip's supposed credentials, Winthrop replies "that he thought the gentleman scarcely needed other than he carried in his language and deportment" (155). While Sir Philip's principles are untested and Everell clearly rests on puritanical principles, Sir Philip remains the preferred choice for Hope because he has all of the seeming of...

Gender And Post Colonial Nation Building In India Essay

Gender And Post Colonial Nation Building In India - Essay Example Focus shifted to the problems of social position of women and to the satisfying of their needs and demands. The main issue of the welfare approach was that Indian women were the object of the programmes designed for their development and they acted the roles of consumers, rather than participants in various agencies. This approach was then recognized as unfortunate due to the narrow range of issues defined as essential for women. These main issues were education, health and domestic violence. Besides, this approach defined that the women should be responsible for the housekeeping only, assigning to them the following roles: housewives, mothers and wives. (Banerjee) The period of the Decade of Women started in 1975 and lasted till 1985. At the beginning of this period the scientists started to speak about separating practical and strategic needs, or interests, of women. Among other authors, Molyneux in 1985 determines these needs and Moser in 1989 described them in detail. Here is the example: "finding food or fuel for the family is a practical gender need; women's issues addressing practical gender needs, which if fulfilled, could lead to an improvement in the condition of women". (qtd in Mohanty) But as the experience shows, to provide constant an... ecessary to remove gaps between gender roles in education in medicine, but providing such changes only won't significantly change women's position in the society. The specialists speak about the changes that are to be provided at first on the level of morals. It is necessary to make the notion of gender equity be recognized in the society, and ideological changes are to be provided to reshape social patterns in the state. (Buch) Conception of "strategic gender needs" appeared during the period of Decade of Women, and the process of gender planning started. The purposes of gender planning were elimination of gender discrimination and accepting gender mainstreaming. The concept of gender mainstreaming "meant that the 'Ladies Compartment' approach of having one Gender Unit or a single Ministry for Women be abandoned, because land reforms, fisheries development, trade, school curricula, road construction, taxation, conflict resolution, etc., were all as much the concerns of women as of men". (Mohanty, p.6) All these issues were recognized as those that have different influence on men and women, and, accordingly, demanding different strategies and approaches. Thus, the activists of the movement required that each programme worked out by the government, should include gender analysis, based upon key interests and demands of genders. It was also necessary to create an institution to control this process and to offer the direction of the changes to be made. It was planned that this institution would be provided with high power and would be financed good, and would focus on the women's interests, needs and demands. The authors describe this condition the following way: "Strategic gender needs were identified as ones that challenged the existing division of labour and catalyzed

Data Driven Marketing Assingment Assignment Example | Topics and Well Written Essays - 1250 words

Data Driven Marketing Assingment - Assignment Example By disaggregation, the present value of lifetime  customer  cash flows are seen in two main ideas: how much cash a customer  pays per period and how many periods a  customer  pays.  Customer  longevity is often associated with loyalty. Analysis in Cell2cell is based on the Net Present Value (NPV) principle: Customer  NPV = PV of lifetime  customer  cash flows - acquisition costs PV of lifetime cash flows = cash flow per period x number of period Cell2cell wireless telecom has a more formal and regular interaction with customers through their service sales points, where various issues and technical problems are resolved. Cell2cell runs two major payment packages: post paid and prepaid payment plans. With the prepayment package, many customers who are not very interested in bills or may not be able to afford a post payment plan can enjoy the flexibility of cellular network services over easily absorbed or smaller bill packages lower than a dollar, this is an effecti ve means of generating revenue for Cell2cell. Customers in general prefer lower priced goods yet they value quality, in line with the demand theory â€Å"the lower the price, the more the quantity demanded.† A predetermined billing arrangement with customers on the post pay plan pronounces ease in predictability in terms of cash flow streams. Even at the prepaid level, the customer still maintains a predictable line rental fee. A reasonable amount of data is stored in the archives of Cell2cell on the numerous customers. Based on relationships, behavioral patterns, income levels, social criteria, nature of business, emotional complexities, and a number of factors, Cell2cell makes adscititious predictions on cash flow streams. Churning is possible if total utility falls, the sum of utilities from each quantity consumed, of the goods and services provided by Cell2cell, from one to the number actually consumed. Utility denotes satisfaction or benefit, utility is essentially based on individual feelings and not on things which have objective or physical existence and it relates to a particular time. Timing for Cell2cell introduces bundling, adding new products contributes massively in cutting down churning. Model Predictions for Cell2cell - Predictive modeling support churn management by tagging customers likely to churn - Campaign targeted to the most profitable at-risk customers - Customers on high risk churning percentage should first be sorted by profitability Factors Driving Churn Telecommunication has seen considerable increase in efficiency, growth and profitability. Growth in the industry for the players has meant fierce competition, consumers on the other hand are more and more demanding and to sustain this continuous need to be on top of the market would mean enchaining affordability and reliability. Ensuring that customer gets full services readily and without any hindrances would mean an extra cost in purchasing more powerful equipments with high speed capabilities, Cell2cell has made a substantial investment in leading edge technologies and has placed itself on a viable platform in retaining the price leader in the market. With poor technologies, the ability to meet the demands of customers is reduced; churning increases and profitability is affected. Customers are very interested in new technologies to do away with boredom, inventing new approaches to business and offering
