The Elegant Universe :: essays research papers

Part I: The Edge of Knowledge Chapter 1: Tied Up with Strings This is the introductory section, where the author, Brian Greene, examines the fundamentals of what is currently proven to be true by experimentation in the realm of modern physics. Green goes on to talk more about "The Basic Idea" of string theory. He describes how physicists are aspiring to reach the Theory of Everything, or T.O.E. Some suspect when string theory is completely understood that it might turn out to become the T.O.E.Part II: The Dilemma of Space, Time, and Quanta Chapter 2: Space, Time, and the Eye of the Beholder In the chapter, Greene describes how Albert Einstein solved the paradox about light. In the mid-1800's James Maxwell succeeded in showing that light was actually an electromagnetic wave. From this he concluded that light always travels at the speed of light. It never slows down. Einstein asked the question: "What happens if we chase after a beam of light, at light speed?" From reasoning based on Newton's laws of motion, one can assume that the light would appear stationary. But according to Maxwell's theory, light cannot be stationary. Einstein solved this problem through his special theory of relativity. Greene continues with his explanations of the special theory of relativity.Chapter 3: Of Warps and Ripples Green begins the chapter by describing "Newton's View of Gravity" and continues by discussing the incompatibility of Newtonian Gravity and Special Relativity. The author also talks about how Einstein discovered the link between acceleration and the warping of space and time. Greene also discuses the basic aspects of General Relativity. He later points out how the two theories of relativity effect black holes, the big bang, and the expansion of space.Chapter 4: Microscopic Weirdness This chapter describes, in detail, the workings of quantum mechanics. The author tells of how waves are effected by quantum mechanic. He also discusses the fact that electromagnetic radiation, or photons, are actually particles and waves. He continues to discuss how matter particles are also matter, but because of their h bar, is so small, the effects are not seen. Green concludes the quantum mechanics discussion by talking about the uncertainty principle.Chapter 5: The need for a New Theory: General Relativity vs. Quantum Mechanics This chapter compares the theory of general relativity and quantum mechanics. It shows that relativity mainly concerns that microscopic world, while quantum mechanics deals with the microscopic world.

Fast Food Nation Essay

Of all non-profit organizations involved in the improvement of food handling, S. T. O. P or Safe Tables Our Priority deserved to be supported by the government as it had effectively acted as public health organization dedicated to preventing illness and death from food-borne pathogens. Since 1993, S. T. O. P had advocated changes in US public policy, widely educated and had done massive outreach, provided assistance to the victims of food-borne diseases, and implemented in-depth studies based on victims’ experience and listed them in the organizations’ registry so as for them to study the long-term consequences of food-borne disease. Historically, the organization was borne out of united anguish of parents of E. coli O157:H7 victims brought about the mishandling of foods by Jack in the Box hamburgers. Given its substantial numbers of victims, it has reached a nationwide attention of the public and the media. The group has presented itself with a clear mission of propagating food safety rules and regulations that would safeguard and inform the American populace on the seriousness of the illness. And since there was no existing organization as such, S. T. O. P. ’s membership had radically increased. Now everyone worries about the nutritional implications of excessive dining at fast-food restaurants and food safety issues. Moreover, their national visibility has soared as they were frequently contacted by media sources. Since then, new programs across the nation had run five different shows discussing meat, seafood, poultry, produce and even fruit juice safety guidelines for the sake of public education. Because of the mass media channel, food industry and legislative officials had taken action and highlighted the issue of food safety whereas before none had done at all. Through the media mileage S. T. O. P. ’s mission had a pivotal momentum as media had effectively assisted its advocacy and legislative efforts that had resulted to reform of food safety in the United States. Current food safety strategy followed by both the government and industry places far too much emphasis on consumer behavior. This over-emphasis on consumer education fosters the misleading impression that it is the consumers’ responsibility to make sure their food is safe, and if people get sick, it is their own fault. Furthermore, through their research they had found out that there were government agencies that lacked efficient communication when the said outbreak happened. They also found out that there were agencies of the government that are aware of the emerging food-borne pathogens however they lacked propagation of the knowledge nor do they have any comprehensive plan to resolve it. According to their study, the USDA (Department of Agriculture), the Congress and the media had failed to inspect these food products and aren’t aware of the massive growth in numbers of its victims. Moreover, S. T. O. P. had joined Safe Food Coalition, an organization with twelve consumer groups that advocated food safety. After several, extensive communication with USDA S. T. O. P. had became a catalyst for change as they were invited to join at policy making table and became a key player in assisting and promoting the launching of food handling inspection after ninety years. They endorsed microbial testing for animal fecal contamination like Salmonella and E. coli. They implored government agencies to reform their policies and address improved food handling. They implored that medical professional for humans and not just veterinarians to work at USDA. They implored for USDA to eradicate conflict of interest in view of the fact that both the marketing and the inspection of food handling is under the same department. In addition, the organization had promptly become the shelter of food-borne victims. They had received frequent telephone calls inquiring about the disease and S. T. O. P. had distributed packets of information from consumers to households. Members had helped try save victims and their families through anchoring various lectures for those struggling with the medical and emotional repercussions of the disease. Then in 2003, S. T. O. P. had launched a groundbreaking report entitled, â€Å"Why Are People Still Dying from Contaminated Food. † It reports the food safety challenges and their recommendations. They advocated that everyone should address the problem from the start of food handling fro instance by keeping pathogens out of the food supply. Also, they had distributed this information through mailings, newsletters and currently through E-alerts. These medium had discussed numerous food-borne diseases such as Pathogens 101, E. coli 0157:H7 bacteria, viruses like Hepatitis A and Norovirus among others, parasites from foods such as Cryptosporidium and others, other syndromes and conditions like Hemolytic Uremic Syndrome (HUS), nvCJD (Mad Cow Disease) and reactive Arthritis/Reiter’s among others, numerous miscellaneous illnesses from digested metals, toxins, prions or wasting diseases and even plastics. Suffice it to say in its endeavor to combat food-borne bacteria S. T. O. P. has had many successes as they focus on advocacy, victim support, outreach, and safe food education. For more than fifteen years they already had worked with both national and local media, responsive food industry trade groups and firms, government agencies such as the Congress, USDA, Food and Drug Administration (FDA), Health and Human Services (HHS), and the Centers for Disease Control (CDC). Through various television segments such as S. T. O. P. in the News, numerous newsletters, teleseminars and podcasts, press releases, media kits, special events and reports, speaking engagements, and online educational resources, the organization had brought about a drastic change in the eating lifestyle of Americans. Thus, the government should be supporting such agencies that clearly promote safety on its constituents.

Recognize and Use Clauses in English Grammar

A clause is the basic building block of a sentence; by definition, it must contain a subject and a verb. Although they appear simple, clauses can function in complex ways in English grammar. A clause can function as a simple sentence, or it may be joined to other clauses with conjunctions to form complex sentences. A clause is a group of words that contains a subject and a predicate. It may be either a complete  sentence (also known as an independent or  main clause) or a sentence-like construction within another sentence (called a dependent or subordinate clause). When clauses are joined so that one modifies another, they are called matrix clauses. Independent: Charlie bought a 57 Thunderbird. Dependent: Because he loved classic cars Matrix: Because he loved classic cars, Charlie bought a 57 Thunderbird. Clauses can function in several ways, as outlined below. Adjective Clause This dependent clause (adjective clause) is also known as a relevant clause because it usually contains a relative pronoun or relative adverb. It is used to modify a subject, much as an adjective would, and is also known as a relative clause. Example: This is the ball that Sammy Sosa hit over the left-field wall in the World Series.   Adverbial Clause Another dependent clause, adverbial clauses function like an adverb, indicating time, place, condition, contrast, concession, reason, purpose, or result. Typically, an adverbial clause is set off with a comma and subordinating conjunction. Example: Although Billy loves pasta and bread, hes on a no-carb diet. Comparative Clause These comparative subordinate clauses use adjectives or adverbs such as like or than to draw a comparison. They are also known as proportional clauses. Example: Julieta is a better poker player than I am. Complement Clause Complementary clauses function like adjectives modifying a subject. They usually begin with a subordinating conjunction and modify the subject-verb relationship. Example: I never expected that you would fly to Japan. Concessive Clause A subordinate clause, the concessive clause is  used to contrast or justify the main idea of the sentence. It is typically set off by a subordinating conjunction. Example: Because we were shivering, I turned up the heat. Conditional Clause Conditional clauses  are easy to recognize because they usually begin with the word if. A type of adjectival clause, conditionals express a hypothesis or condition. Example: If we can reach Tulsa, we can stop driving for the night. Coordinate Clause Coordinate  clauses usually begin  with the conjunctions and or but and express relativity or relationship with the subject of the main clause. Example: Sheldon drinks coffee, but Ernestine prefers tea. Noun Clause As the name suggests, noun clauses  are a sort of dependent clause that functions as a noun in relation to the main clause. They are typically offset with that, which, or what. Example: What I believe is irrelevant to the conversation. Reporting Clause The reporting clause is more commonly known as attribution because it identifies who is speaking or the source of what is being said. They always follow the noun or noun clause. Example: Im going to the mall, shouted Jerry from the garage. Verbless Clause This kind of subordinate clause may not seem like one because it lacks a verb. Verbless clauses provide tangential information that informs  but is not directly modifying the main clause. Example: In the interest of brevity, I will keep this speech short.
