Astronomy As a Natural Science - Essay Example The cosmology  encompasses the study of the universe as a whole. Such prehistoric cultures include the Nubian and Egyptian monuments and other early civilizations such as the Iranians, Maya, Chinese, Greeks, Babylonians and the Indians. There was the need to invent the telescope before astronomy made it into the modern science. Astronomy has historically included disciplines ranging from astrometry, observational astronomy, celestial navigation and the making of calendars (Trumper, pg. 11). Currently, astronomy is considered synonymous with astrophysics. In the twentieth century, astronomy split into theoretical and observational branches. Observation astronomy focus on acquiring data from various observations of astronomical objects that is then analyzed using basic principles of physics. On the other hand, theoretical astronomy is oriented towards computer development or analytical models that describe the astronomical phenomena and objects (Renner et al., pg. 618). Thomas Harrio t was the first person, four centuries ago, to look like a celestial object using a microscope. He used his simple Dutch trunk telescope to view the moon in the late 1600s and made drawings of the observations (Basu and Matzner, N. p. 115). Thomas was operating within the same time as Galileo and actually, Thomas did his observation before Galileo. Both Galileo and Thomas were astronomers. They spent time in studying celestial bodies more so the moon. They both developed an interest in studying the lunar. Unlike Galileo, Harriot did not publish his observational drawing though he was able to share his telescopic findings with a group of English correspondents. They both drew â€Å"moon maps† and they believed to be the geographical surface of the moon to be (Hyslop, pg. 293). The type of moon maps, in this case, is well illustrated in some literature writings such as in the School of Night where a letter is missing and the search result to the discovery of buried gold and cod ed maps (Bayard, 2010). This book was written in the 16th century. These coded maps are actually some of the drawings by Thomas and Galileo.

US Airways Group - Putting It All Together Essay

US Airways Group - Putting It All Together - Essay Example In a market characterized by low-fares, high volumes, traditionally basic services such as in-flight meals and movie were included in the fare price but in today’s fierce operating environment airlines have resulted to charging extra for these services in an effort to offer the lowest selling price possible for the passengers. U.S. Airways is suffering from an image problem, where it is collectively viewed as one of the least admired corporations in its industry sector. In the Fortune 1,000: Most Admired Companies 2006, U.S. Airways received the lowest score out of ten of the major airlines in the U.S. Even in the 2011 Fortune survey with added competition from other major airlines out of the twelve companies surveyed only AMR received a lower score than U.S. Airways. Furthermore it has not improved in any of the attributes surveyed in the study (Cnn, 2011). It is clear that U.S. Airways needs to address its quality of service in order to increase its market share in the domestic market as well as successfully entering into the global airline market. The airline industry in general is very susceptible to external economic, legal and political factors which can deeply affect its day to day operations. The recessionary economic conditions in the domestic economy as well as internationally significantly affec ted the airline industry particularly in the years 2008-2009 where most major airlines reported operational losses. Price gouging and intense competition have been a defining characteristic of the industry ever since the deregulation of 1978. After the 2010 travel season with slight improvement in the domestic and global economy the airline industry has been able to bounce back maintaining full occupancy rates for its flights and has once again reached profitability (Yahoo, 2011). One of the biggest costs for any airline is the cost of fuel, so in general the industry is particularly vulnerable to fuel price increases (Datamonitor, 2011). Regardless, rising costs and the volatility of fuel prices has cut the average margin of the airline industry to only 2%.U.S. Airways as a whole needs to improve the customer satisfaction rate by improving their customer service, improving the quality of its services, and decreasing the percentage of delayed flights. They also need to improve the s peed of the boarding process in order to improve customer satisfaction. These are some of the things that U.S. Airways management needs to address in order to improve their market share and increase revenues. The airline industry has always been characterized for being a highly regulated industry with various federal agencies overseeing their operations from a safety and security standpoint. The Federal Aviation Administration (FAA) is responsible for regulating and ensuring the overall safety of all civilian as well as commercial flights in the domestic airspace. All airlines operating in the domestically are subject to the rules and regulations of the FAA. The FAA has the authority to issue any directives or changes in procedures, including aircraft maintenance. For U.S. Airways the adequate planning and budgeting of enough cash reserves, manpower, airplane inventory and financial resources to meet with the changing operational demands of running a domestic and global airline must be factored in the strategic and contingency planning of the company. There is a high degree of complexity in the operation, maintenance and repair of commercial aircrafts. As a consequence there is a high level of added costs
