Copernicus Essays - Copernican Revolution, Ancient Greek Astronomy

Copernicus Essays - Copernican Revolution, Ancient Greek Astronomy Copernicus Nicolas Copernicus Nicolas Copernicus 1473-1543 Physics February 8, 2000 Nicolas Copernicus Nicolas Copernicus 1473-1543 Copernicus was born in Poland in 1473, he started his education at Cracow University. There he studied mathematics and optics. From here he went to Italy, where he was appointed as a canon in the cathedral of Frauenburg, where he spent a comfortable academic life studding. Copernicus had some small hobbies while at the cathedral, he painted, and frequently translated Greek poetry into Latin. One other hobby that just wasn't small enough to be called a hobby to most of us was astronomy. He made investigations quietly and alone, without any help. He observed from a turret on a protective wall around a cathedral, he also looked with his naked eye rather than with a telescope. He was one of the founders of modern astronomy. Copernicus died in 1543 of a cerebral hemorrhage. In 1530 right before Copernicus died he managed to published his work, De Revolutionibus. Which said that the earth rotated on its axis once daily and traveled around the sun once yearly. This might no sound very controversial but at this time the church and its followers believed in the Ptolemiac theory, which stated that the universe was a closed space bounded by a spherical envelope beyond which there was nothing. (Landry 1999) Copernicuss works went against the church, and most scientific beliefs. This may be one reason why Copernicus didnt publish his work until his deathbed. Another reason may be that Copernicus was a huge perfectionist, and continuously redid his works over and over to get them right. (Field 1995) So you can see why Copernicus wasnt in any big rush to have the world know about his theory. On one hand he would cause a Nicolas Copernicus tramoundous stir in the church, and all the scientific community. He wouldve most likely have been fired from the comfortable church position he had for many years, and couldve given him a bad name. If it hadnt been for George Rheticus, a 25-year-old German mathematics professor Copernicuss might have never publiched his work. (Field 1995) Rheticus stayed with Copernicus for two years, and convinced him to release his work. His work the Copernicus's heliostatic cosmology involved giving several distinct motions to the Earth. It was consequently considered implausible by the vast majority of his contemporaries, and by most astronomers and natural philosophers of succeeding generations before the middle of the seventeenth century. Its only defenders included Johannes Kepler (1571 -1630) and Galileo Galilei (1564- 1642). Strong theoretical underpinning for the Copernican theory was provided by Newton's theory of universal gravitation (1687). (Field 1995) So Copernicuss whole argument stated that the planets and the Earth were in orbit around the sun, and the moon was in orbit around the Earth. This is called the The Heliocentric System: Nicolas Copernicus In conclusion Copernicus said that the Sun was the center of the universe, and went against all known knowledge, religion, and teachings. He took all his observations with the naked eye and with no help. Many disregarded his book and his theory, which went against everything that the church believed in. However if it wasnt for Copernicus, modern astronomy would have never made advances as far as it has to today. Copernicuss hard work and strength is why he is one of the most important founders of modern astronomy. Bibliography Field, J. V. (1995 August). Home page. [Online]. [2000, Feb. 8].

Economic topic - Assignment Example This paper, therefore, explains the empirical evidence on different roles played by the history and geography on the international finance and how they are inter-connected in improving the investors desires in the market. Over the recent years, geography has been seen as the growing interests of the international finance, particularly, on the studies of using the gravity models. The models were being used to determine the direction of the cross border financial flows and stocks. Using this approach, the bilateral trade in assets is deemed to increase depending with the size of the country and also decline with information asymmetries and transaction costs. This is because they are being captured by geographical distance and the variables relating to it (Portes and Rey, 2005). Furthermore, there has been a lot of empirical work on the gravity but has taken place without a theoretical foundation which can stand firm on the matter of financial holdings for cross-border. Anderson and van Wincoop (2003) gave an analysis that the estimated gravity equations which are not being founded in economic theory can result to biased estimations since some variables are omitted. It also leads to comparatives with an incorrect static analysis which doesn’t consider the general equilibrium effects of changing the cross border barriers. Different sources of literature such as Clemens and Williamson (2004) highlight the important trend and progress of the financial globalization since 1990s although it has not analyzed the historical forces which have influenced the international investment for a longer period of time. The existing literature also doesn’t highlight the applicability and generality over time of the emphasized factors on the standard framework. These shortcomings aroused the interests of writing this paper in order to be addressed accordingly. The paper gives a clear discussion on the issue by estimating the gravity model the international investment u sing an example of information on Us investors’ holdings. The history an effect is being tested through the past holdings influenced the current holdings (Eichengreen and Irwin, 1998). The aspect on how the past investment influences the current investment is through the fixed costs. The empirical evidence and literature theories have shown the permanent impacts on trade patterns as a result of mart penetration. This is due to the fixed costs incurred by firms when entering into the new market which they can’t get when exiting the same market (Dixit, 1989). The passing shocks of literatures can be cumulated to impact a more powerful still which can lead firms to penetrating the market and have the ability to learn more about the market in question thereby, have the advantage of having the initial information of the market. This helps many organizations to analyze the conditions of the current market with the information contained of the past before deciding on which st rategy to be used in penetrating the larger market. In simple terms, the historical theories and literature helps many companies to be prepares on the impacts as many firms have been penetrated in the past. As it is currently penetrating, hence, there
