Outline On Galileo Galilei

Outline On Galileo Galilei Thesis statement main argument The astronomer Galileo Galilei contributed to the field of astronomy majorly by observing the sky with a telescope he had built, observations which resulted in his discovery of many astronomical phenomena further proving that the Earth was not the center of the solar system. Statement of purpose (scope of the essay): Following a brief biography of Galileo Galilei, this paper will determine the state of the scientific knowledge prior to Galileos astronomical discoveries, explain what Galileos contribution to astronomy was, and discuss how his findings subsequently changed humanitys conception of the universe. Body Topic sentence of paragraph 1: Besides being known as a very influential astronomer, Galileo Galilei was also known for being an Italian scientist and philosopher. Birth date: February 15, 1564; Place of birth: Pisa, Italy. (Galileo Biography, 2013) Death date: January 8, 1642; Place of death: Arcetri, Italy. When he died, he was blind and very ill, and was under house arrest for heresy. (Galileo Biography, 2013) Galileo first started in a monastery school because he wanted to become a monk, but he eventually left the monastery and attended the University of Pisa to study medicine, like his father wished. However, he never completed his medicine degree and instead found an interest in mathematics and philosophy. (Bellis, 2013; Galileo Galilei, 2013) Galileo taught for three years at the University of Pisa, but transferred to the University of Padua when his three-year contract at Pisa ended. (Bellis, 2013) In 1609, Galileo heard rumours of a spyglass having been created by a Dutch spectacle-maker. Galilei decided to create his own spyglass, later renamed a telescope, and eventually made it more powerful than the Dutch spyglass. One night, he pointed his telescope towards the sky and his astronomical discoveries began then. (Bellis, 2013) Topic sentence of paragraph 2: Prior to Galileos astronomical contribution, the Catholic Church and the Bible were the principal sources of explanation for most of the phenomena that occurred on Earth and in space. In that time period, the geocentric model, suggested by Claudius Ptolemy at the beginning of the 2nd century A.D., argued that the Earth was in the center of the solar system and that the other planets and the Sun revolved around it. This model was widely accepted and encouraged by the Catholic Church. (Mochà ©, 2009; Redd, 2013) However, a more recent model had been brought forward by Nicholaus Copernicus, in 1543. This model was called the heliocentric model and declared that the Earth was not in the center of the solar system, but rather that this place was occupied by the Sun and that all the planets, including the Earth, rotated around the Sun. (Mochà ©, 2009; Redd, 2013) Galileo Galilei supported the Copernican theory (Galileo Biography, 2013), but this theory was considered against the teachings of the Church. As a result, Copernicus writings were banned by the Church. (Machamer, 2009; Mochà ©, 2009) Topic sentence for paragraph 3: Galileo Galilei made more than one contribution to the field of astronomy by observing the sky with his telescope, but his major discoveries were the first moons of Jupiter and the phases of Venus. His two major discoveries provided proof that the heliocentric model, introduced by Copernicus, was truly the one that was representative of the solar system. (Mochà ©, 2009; Weisstein, 2007) The moons of Jupiter (*the names of those moons will be included in the final essay*) that Galileo observed rejected the geocentric models argument against the Copernican theory. This argument stated that if the Sun was the center of the solar system, Earth would lose its moon because it circulated around the Sun; Earth could only keep its moon if it was in the center. However, with the moons of Jupiter (later named the Galilean moons in honour of Galileo) rotating around Jupiter, the scientist community could only face the fact that a planet could keep moons, even though it was not in the center of the solar system. (Mochà ©, 2009; Galileo Biography, 2013) The phases of Venus further encouraged the heliocentric model. The phases of Venus indicated that Venus must circle the Sun for its phases to be visible from Earth, just like the phases of the moon were. In the geocentric model, Venus would show no phases and would always be a crescent shape because the Sun would not be in the center of its orbit. (Mochà ©, 2009; Galileo Biography, 2013) Topic sentence of paragraph 4: Although Galileos observations and discoveries were not first accepted by the religious community, evidence of Galileos findings started to circulate and the Church was eventually forced to admit that Galileo had been right. (Galileo Biography, 2013; Bellis, 2013) Galileo had already published multiple books (*the names and dates will be included in the final essay*) prior to being charged of heresy by the Church and placed under house arrest. (Galileo Biography, 2013; Bellis, 2013) While being under house arrest, Galileo continued to write and publish books (Galileo Biography, 2013; Bellis, 2013), although he was becoming blind from having stared too much at the Sun with his telescope for another of his astronomical discoveries. (Our solar system, 2011) In 1758, the Church was forced to face the truth and lifted the ban on most of the books that supported the Copernican theory and the heliocentric model. In 1835, it abandoned its opposition against this model completely. (Galileo Biography, 2013) In the 20th century, some popes acknowledged the revolutionary work done by Galileo. In 1992, Pope John Paul II publicly apologized and showed regret on how the case of Galileo had been delt with. (Galileo Biography, 2013; Bellis, 2013) Conclusion Restatement of thesis statement: Galileo Galilei significantly contributed to astronomy primarily by observing the sky with a telescope, which resulted in his discovery of many astronomical phenomena proving that the Earth was not the center of the solar system. Summary of main points: Prior to Galileos findings, the Church believed in the geocentric model, introduced by Claudius Ptolemy. However, Galileos discovery of the moons of Jupiter and the phases of Venus instead supported the heliocentric model, suggested by Nicolaus Copernicus. Galileos contribution took a long time to be recognized, but it allowed for a better understanding of the way the solar system functions. Other discoveries based on the astronomers contribution: Galileos use of a telescope to observe the sky also allowed him to observe the Suns dark patches known as sunspots, part of the star cloud of the Milky Way, the rings of Saturn that he identified as ears, and the Moons crater-covered surface. (Mochà ©, 2009) There is also recent evidence that Galileo may have discovered Neptune nearly two centuries before it was official found by satellites and modern telescopes.

Ib Economics Commentary 1 †Microeconomics Essay

Rebecca Bundhun, (October 19, 2012) Cost of summer getaways hit as air ticket prices rise, The National, http://www.thenational.ae/thenationalconversation/industry-insights/tourism/cost-of-summer-getaways-hit-as-air-ticket-prices-rise The cost of an airline ticket can fluctuate tremendously based on a number of factors. The goal of airlines is to maximize their capacity by having the greatest number of passengers on all trips. This may however be difficult, as airlines pricing is not only dictated by their own operating costs and profit margins required but they have to consider complementary items that could have an effect on supply and demand for their product. By definition, demand theory explains the inverse relationship between quantity and price. This law explains that if the quantity available of a product or service wanted by the public is low, the price for that product or service will be high. As demand for a product or service increases, the price will increase. This law is critical as we are able to predict prices based on the demand of a product. In the case of airlines, they are able to predict that prices for their services will go up during the high travel months. People are willing to pay more for travel during the summer months, as they know that supply is limited and their available time is defined by their vacation schedules. If we were to graph this scenario, we would find that price and quantity relationship creates a maximum efficiency point called equilibrium point. The equilibrium point tells us the best combination of price and quantity. With the graph below, we can illustrate that some travelers will be forced to cancel their travel plans due to high ticket costs, just as we can identify travelers that will have to fly no matter what the cost of the fare is. However what economists tend to focus on is trying to find an equilibrium point between price and quantity. As we know, airlines provide a service to clients by connecting passengers to desired destinations worldwide. Although prices tend to be set by supply and demand, they are also exposed to externalities. An externality occurs when the actions of consumers or producers give rise to positive or negative side effects on other people, who are not part of these actions and whose interests are not taken into consideration. A perfect example of a negative externality is the rise of jet fuel. As a barrel of oil rises, the price of jet fuel also rises and consequently the price of an airline ticket also rises. Externalities can create a positive or negative demand or effect on a product or service. Price elasticity of demand is a term that helps us understand the measure of the responsiveness of the quantity demanded to changes in price. In general, if there is a large responsiveness of the quantity demanded, the demand is referred to as being elastic, if there is a small responsiveness, demand is inelastic. Airlines take advantage of the existence of inelasticity. Mr. D’Souza states in the article, â€Å"People are still flying. People traditionally plan these breaks, and regardless of the price, they fly. The demand is very, very high.† On the contrary, airlines understand price elasticity and use this well. They know that fare prices can be considered both elastic and inelastic based on the circumstance the traveler finds themselves in. Airlines study their client base, their competitors, and use patterns to predict the behavior of clients based on the condition. They know the probabilities of travelers changing to an alternative airline if their price rises, if they modify their routes, but most of all, they use price elasticity to predict the success of promotions offered by themselves or any other competitor. Airlines want to lure business by creating special values and convince unplanned tourists to take the trip. Say an average ticket price from Dallas to Las Vegas is $550.00; airlines will create a promotional price and may offer the same route for $199.00. Since the price is so low, people will often forget that they are taking an unplanned trip and will justify the trip by thinking about the cost savings realized and not of the unplanned expense. The demand curve below shows how changes in price lead to changes in the quantity demanded. Although airline tickets are considered elastic and inelastic, most economists consider it elastic unless travel is done for business use. Domestic airline travel can be substituted by bus transportation, automobile, train etc. Airline travel is elastic especially as the person’s income increases so their opportunity for travel increases and they will be more likely to afford the variation in cost.

Additionally, ways for management to motivate Susan have also been identified. 1. Physiological Needs: Food, Water, Warmth, Rest. - Susan is a 30 year old wife, mother of two young children, and LPN of 10 years. She has also worked more than normal the last few months, due to the rising inpatient census. It is likely Susan is tired. - Management can help by ensuring schedules are fair, nurses have the opportunity to take breaks, and ensure over-time is evenly assigned to nurses. 2. Safety Needs: Security and Safety. - Susan’s husband is a lawyer so it can be inferred financial distress is not a cause of dissatisfaction. Susan could have some concerns of new employees not following proper protocol to ensure patient safety. - However, Jane can ensure Susan’s benefit package is fair. Jane could make observation rounds on other employees, to ensure they are following best practices. 3.
