Greek mathematician Pythagoras Essay Example for Free

Greek mathematician Pythagoras Essay Pythagoras was a Greek philosopher and mathematician. He was born in Samos, Ionia around 580 b.c. Thales, who was another philosopher was the main teacher of Pythagoras. Pythagoras went to study further in Egypt so Thales couldnt teach him anymore. In Pythagoras teenage years, he began to become known for his philosophic ideas. He also succeeded in math, astronomy, wrestling, and music. In music, he figured out that when a string is vibrating, the longer or shorter it is makes a difference in the tune of the note. In astronomy, he taught that the earth was a sphere, and in math he compared the difference between composite and prime numbers, discovered irrational numbers, and proved the Pythagorean Theorem. This stated that when the two shorter sides in a right triangle were squared and then added, it would equal the square of the longest side or hypotenuse. This was known earlier, but he was the first one to really prove it was true. He soon moved from his home in Italy to a place called Crotona. In Crotona, he found a wife named Theano and founded a school based on philosophy and religion. While in Crotona he discovered many things and even had some followers. Pythagoras followers called themselves the Pythagoreans. In order to become a Pythagorean , you had to follow a couple of strict rules. One of the rules was silence. This meant that you could never share any of your own ideas with the others and that you could only listen to your fellow Pythagoreans. Another rule was avoiding the ingestion of meat. An interesting thing about his school was that if you joined you were automatically a Pythagorean so that meant if you were a student, youd have to obey the rules also. His followers also believed in reincarnation. Reincarnation- when one dies, their soul is transferred to another human beings body. Pythagoras died in Metapontum, Lucania in 500 b.c. Historians think that he  fled and just barely escaped death when violence broke out in Crotona. When he died, a lot of his ideas were forgotten. We will always miss our dear Pythagorus.

Organic Molecules Challenge :: essays research papers

Organic Molecules Challenge Silicon's Reign as King of Semiconductors There is a revolution fomenting in the semiconductor industry. It may take 30 years or more to reach perfection, but when it does the advance may be so great that today's computers will be little more than calculators compared to what will come after. The revolution is called molecular electronics, and its goal is to depose silicon as king of the computer chip and put carbon in its place. The perpetrators are a few clever chemists trying to use pigment, proteins, polymers, and other organic molecules to carry out the same task that microscopic patterns of silicon and metal do now. For years these researchers worked in secret, mainly at their blackboards, plotting and planning. Now they are beginning to conduct small forays in the laboratory, and their few successes to date lead them to believe they were on the right track. "We have a long way to go before carbon-based electronics replace silicon-based electronics, but we can see now that we hope to revolutionize computer design and performance," said Robert R. Birge, a professor of chemistry, Carnegie- Mellon University, Pittsburgh. "Now it's only a matter of time, hard work, and some luck before molecular electronics start having a noticeable impact." Molecular electronics is so named because it uses molecules to act as the "wires" and "switches" of computer chips. Wires, may someday be replaced by polymers that conduct electricity, such as polyacetylene and polyphenylenesulfide. Another candidate might be organometallic compounds such as porphyrins and phthalocyanines which also conduct electricity. When crystallized, these flat molecules stack like pancakes, and metal ions in their centers line up with one another to form a one-dimensional wire. Many organic molecules can exist in two distinct stable states that differ in some measurable property and are interconvertable. These could be switches of molecular electronics. For example, bacteriorhodpsin, a bacterial pigment, exists in two optical states: one state absorbs green light, the other orange. Shinning green light on the green-absorbing state converts it into the orange state and vice versa. Birge and his coworkers have developed high density memory drives using bacteriorhodopsin. Although the idea of using organic molecules may seem far-fetched, it happens every day throughout nature. "Electron transport in photosynthesis one of the most important energy generating systems in nature, is a real-world example of what we're trying to do," said Phil Seiden, manager of molecular science, IBM, Yorkstown Heights, N.Y. Birge, who heads the Center for Molecular Electronics at Carnegie-Mellon, said two factors are driving this developing revolution, more speed and less space. "Semiconductor chip designers are always trying to cram more electronic

Of Mice and Men- Candy character analysis Essay

Steinbeck presents Candy as a vulnerable character. He does this by referencing him as an â€Å"old man† before citing his name, using pre-modification; so that the reader instantly knows not only his physical state but maybe that metaphorically he is a weak person. He is also shown to be desperate throughout the opening of chapter 2, where he tries to make friends with George and Lennie as soon as he meets them. He gossips about other people on the ranch and makes sure George â€Å"won’t tell Curley nothing†. This quote alone indicates Candy is lonely and just wants to have friends but deep down is afraid of the other men on the ranch, implying he doesn’t have many friends on the ranch at all, therefore he needs to be welcoming and confident towards George and Lennie to gain their friendship but this quote gives away his fear of Curley finding out he was talking about him and throwing him off the ranch, leading the reader to believe the ranch is the only place Candy can call home. This idea of Candy being completely alone and having no where else to go is reinforced when Steinbeck introduces Candy’s â€Å"ancient dog†, the use of pre-modification again this time with the word â€Å"ancient† helps to show that like his owner this dog is old, the lexis â€Å"ancient† has the connotations of being so old it could be considered an artifact or piece of history, this concept could suggest that Candy’s dog is in fact a part of the history of the ranch that is why he is still there because even though his dog is old and useless he is still allowed on the ranch even with no purpose, just like Candy staying on the ranch with no hand, meaning he cannot do any proper jobs except â€Å"settin’ out the wash basins†. However when Steinbeck introduces the dog at first, Candy says â€Å"my dog†, this possessive lexis could suggest Candy is proud of his dog especially as he goes on to say â€Å"he was a good sheepdog when he was younger†, you could take this quote as a declarative, him protecting but also bragging about his dog. A conflicting idea could be that Candy and dog are similar that is why Candy likes to talk and brag about his dog, Steinbeck writes for both that they are â€Å"old† and â€Å"ancient† but both are disabled in that Candy has lost his hand and the dog is so old and decrepit it cannot hunt or feed itself. Both are looking for a companion that could take care of them, they have a codependent relationship. This idea could be considered a recurring theme as some say Lennie and Georges’ relationship is co-dependent, even though George wouldn’t admit it due to his controlling personality. So the reason Candy brags about his dog is because he really wants to prove himself, and that he was in fact worthy of being on the ranch. This point of Candy and his dog being similar supports my original idea, which was that using the descriptions of Candy and his dog we find that Candy is in fact just like an old animal, a useful and valued member of any ranch as opposed to just something that takes up space, money and food.

How might an organization create and sustain competitive advantage Essay

How might an organization create and sustain competitive advantage through the strategic use of design thinking Your task for t - Essay Example 2). Design thinking has been shown to be the process through which individuals within organizations identify particular issues and through strategic thinking develop viable solutions, which are mainly focused on improving future results to the organization. It is therefore a process whereby the innovation starts from the goal or purpose intended to be achieved as against from the problems to be solved (Wattanasupachoke, 2012, p. 1; Kevin and Ron, 2008, p. 8-10). Through critical analysis of issues in current as well as future perspectives, design thinking explores the parameters of the issues and then resolutions are explored simultaneously. This system is therefore uniquely applied within trading organizations as against scientific methods, which are adopted for solving problems. Design thinking is therefore an emerging trend that trading organizations are adopting in order to create as well as sustain competitive advantage in business environment against other competing organizatio ns. It is a popular notion among business organizations that yesterday’s innovation can never guarantee tomorrows competence hence the need to encourage the innovation spirit (Maier and Zenovia, 2011, p. 975). Manufacturing and technical organizations are basic examples, which adopt effectively the design-thinking framework. In such an example to an organization, which bears the traits of manufacturing and technical attributes, we consider the Volkswagen automotives company. This project therefore has the main objective as being the analysis of design thinking as an effective tool to be adopted within the locomotive industry with a special attention to Volkswagen. The Volkswagen is a brand name for a group of entrepreneurs; companies whose main area of operation is within the automotive industry. They are well known for the manufacture and sale of the Volkswagen, Audi, Skoda, SEAT, Bentley, Lamborghini, Bugatti, and Porsch

Econ reading - Assignment Example On the contrary, Fiat money is the one that does not have intrinsic value. Fiat money may be utilized upon government decree. On the other hand, demand deposits are account balances in a bank that depositors may obtain via writing a check upon request. Therefore, demand deposits should be included in the stock money in order to measure the value of money in the stock (Mankiw, 2011). The U.S Federal Reserve System acts as a central bank, it sets monetary policies in an economy. The Federal group is appointed by the president upon senate approval. Fed can increase the amount money in circulation through open market operation, whereby, Fed can make dollars and utilize them to buy bonds this led to an increase the amount of money in circulation (Mankiw, 2011). On the contrary, banks do not hold 100 reserves because they lend some money to earn profits. The relationship between amount of reserves and amount of money in the banking system a rises because banks accepts deposits from the pub lic and lend out some deposits while ensuring proportion bank reserve is maintained (Mankiw, 2011). If bank A has a leverage ratio of 10, while Bank B has a leverage ratio of 20 whereby, similar losses on bank loans at the two banks cause the value of their assets to fall by 7 percent. The above statement indicates that bank B showed a larger change in bank capital than bank A because its capital value declined twice as much as bank A. However, the two banks remained solvent because they can be able to meet their financial obligation. Connectively, discount rate is an interest rate charged by Fed to commercial banks when advancing loans, when Fed raises discount rates, the amount of money in circulation decreases (Mankiw, 2011). Discount rate is the interest rate charged by Fed to commercial bank on borrowed funds, when Fed raises the discount rates, bank reserve decrease this in turn causes the cost of borrowing to increase. This discourages borrowing and consequently reduces the a mount of money in circulation (Mankiw, 2011). . On the other hand, a reserve requirement is the amount of funds that a bank should retain after advancing loans. Whereby, an increase in reserve requirement causes an increase in reserve ratio, this in turn leads to a decrease in money supply. Additionally, Fed can not perfectly control the supply money because it does not have control of the amount of money held in the pockets of households. Secondly, Fed does not have control of the amount of money advanced as loans by the banks (Mankiw, 2011). 2.) Answer Questions for Review #1 in the middle of page 666 The value of money may be affected through increasing price level. This is because the money tends to lose its value this further reduces the purchasing power of money. According to the quantity theory of money, an increase in quantity of money leads to an increase in inflation rates. In above connection, nominal variables are those measured in monetary terms while real variables are those that can be measured in physical terms. According to the principle of monetary neutrality, nominal variables may be affected by changes in quantity of money. Inflation is like a tax in the senses that when government print money, the amount of money held by people losses value due to increase in money supply (Mankiw, 2011). According to Fishers effect, an increase in inflation rate causes real interest to fall. On the hand, nominal interest rate increases. The cost of inflation may involve menu cost that causes the company to adjust its prices such cost of printing new catalogues, advertising to mention just but a few. The most important cost for the U.S economy is inflation cost because an increase the tax burden
