Keplers Laws and Planetary Movement Essay - 1399 Words

By the turn of the 1600s, the way in which the solar system and the universe as a whole was viewed began to change. With the controversial conclusions of Copernicus, scientists already began to adopt the idea of a heliocentric solar system. Further advancements in astronomy came about through the research of Tycho Brahe and his assistant Johannes Kepler. The three planetary laws developed by Kepler with the data gathered by Brahe shaped the way in which science viewed the structure and motion of the planets of the solar system in profound ways, lasting to this day. A Brief History of Johannes Kepler Johannes Kepler began his studies in astronomy as an assistant to the astronomer Tycho Brahe, whom, by his own right, was a formidable†¦show more content†¦However, with the advent of calculus and Newton tackling the problem, it was proven that this was in fact the case for all celestial bodies. Formal Statement of Kepler’s First Law: Planets move in elliptical orbits with the sun at one focus of the ellipse. The above illustration exaggerates the actual orbit of a planet; an actual orbit is more circular with the two foci of the ellipse close together in the center, but explains the basic concept. With an elliptical orbit, a planet would not maintain a constant distance from a sun. It would, in fact, be closer to the sun at one point in its period than in others. Kepler’s Second Law The idea that Kepler sought most in his dealings with astronomy was a theorem that would have the capacity to predict where a planetary body would be at a particular time. This, of course, would require the knowledge of the velocity of the body at any point in its orbit. The key to solving this problem is finding the relationship between the different velocities of a planet as it travels through its orbit. Kepler’s solution to this problem involved making several assumptions. 1) All planets are driven by a force emanating from their axis of rotation, in other words, the sun. Although we now know this force to be gravity, Kepler viewed it as a ray coming from the sun and acting of a planet as a paddle acts on a boat. 2) This force would decrease at a rate of the inverse of the radius fromShow MoreRelatedEssay on The Scientific Revolution1344 Words   |  6 Pagesconcept of divine design were Robert Boyle (1627 -1691), Johannes Kepler (1571-1630) and Sir Issac Newton (1642- 1727).

The Effect of Pollution on Mount Everest Free Essays

Nepal is the small, one of the poorest country of the world. Yet it is very rich in natural resources and scenic beauty including highest ranges of Himalayas. Nepal is the home of the eight highest mountains out often in the world. We will write a custom essay sample on The Effect of Pollution on Mount Everest or any similar topic only for you Order Now Mountaineers, trekkers and skilled professionals regularly visit to scale the Mountains in Nepal, which has increased the number of tourist in Nepal. In the last decade, people’s attraction toward the mountaineering has increased a lot, by which number of climbers visiting Mount Everest has also been increased. Due to the increasing umber of climbers in the Everest, pollution in and around the Everest has increased and it needs a special attention to prevent from the pollution. Everest attracts people of all around the world. In the past only few climbers who know well about the mountains used to come but today most of the interested people who have enough economic sources visit Himalayas to climb the mountain. According to Norbu Sherpa, a mountain tourist guide, people come to climb Everest as they want to be famous scaling the tallest mountain in the world (Wawahare). In the early 2000s the number f tourist arriving to Nepal was around 400,000 but in last two years people flowing to Nepal has increased rapidly reaching around 900,000 nearly triple of starting 2000s as per the statistics given by the Nepal Tourism Statistics in 2012 (Ministry of Culture, Tourism and Civil Aviation ). As the numbers of climbers has increased, pollution in the highest portion of the peaks has been increased. Pollution in the Everest includes foods, plastics, cans, gas tanks, papers, climber’s equipment, human excreta, and also dead bodies of climbers. According to Norbu Sherpa in the article, â€Å"A Conversation with: Mountain Guide Norbu Sherpa†, if the flow of the climbers is frequent, more and more waste is created (Wawahare). The article â€Å"Everest Maxed Out† published on June 2013 in National Geographic Magazine by Mark Jenkins provides information about his climbing on Everest and the flow of climbers he saw near camp Ill and pollution in the Everest. Jenkins says, â€Å"The two standard routes, the Northeast Ridge and the Southeast Ridge, are not only dangerously crowded but also disgustingly polluted, with garbage leaking out of the glaciers and pyramids of human excrement befouling the high camps. And then there are the deaths. † Pollution due to death of climbers happens especially due to certain change in weather and climbers who is less experienced or trained. Despite of being polluted, Everest fascinates and attracts the climbers toward it every year. As the increasing numbers of trekkers and climbers in the Everest has led to the pollution, government should try to clean up all the wastes in the Everest utilizing the revenue they had earned from the tourism industry. Norbu says, the government earnings through tourism has not been utilize in mountains nor for benefit of Sherpas (Wawahare). Government should make strict rules and laws to punish the people who makes pollution in the Everest. If the Climbers did not bring back their all used equipment’s and the trash from Everest they should lose their deposit money and Sherpas should be rewarded if they brought wastes to the lower base of Everest. And also government, mountaineering agencies should limit the number of people climbing the mountain in every season or month which will not only helps to control pollution but also maintains the traffic Jams in Everest. A climbers, guides and Sherpas should be provided trainings to handle the severe eather condition in mountain so that deaths in the mountains decrease. Decreasing the number of deaths and limiting the number of climbers on Everest pollution will be controlled and also government needs to be aware about the pollution on Everest and utilize their revenue for reducing pollution in mountains. Everest is one of the main factor that world recognizes Nepal, so every concerned individual as well as government and agencies should control pollution. Controlling pollution it will not only preserve the beauty of Everest but also more people can have the glory to scale the Everest in future.

Communication and Feedback in Organizationsâ€Myassignmenthelp.Com

Question: What Is the Role of Communication and Feedback in Organizations? Answer: Introduction Communication and Feedback required for successful management. To survive in the operating market, it is important for every organization to manage its business effectively. Management of the organization has become a concept of focus in the management literature. By effective management, organizations are also able to implement effective change in the business operations whenever it is required. But, there are many researchers who have found that there are organizational programs do not reach to the results due to the lack of effective communication and feedback process in the organization. Poorly managed communication in the organization is the cause of rumors and resistance among the employees (Robbins, 2003). So, communication and feedback can be considered to be the important part of the organization for managing the organization effectively. This essay demonstrates the role and importance of the communication and feedback in the business for managing the organization effectively. The studies revealed that the communication has positive cor relation with the many positive organizational results such as organizational performance, commitment, job satisfaction and the organizational citizenship behavior. Failure in the communication can be the cause of various functionless results i.e. low trust, stress, job dissatisfaction, absence, severance intension, and decrease in the organizational commitment (Tripathi Reddy, 2012). Organizational communication Now, effective and meaningful communication provides information to the employees at the levels of their job roles and motivates them to adopt the innovative business strategies. It is important that there should be the positive attitude among the employees towards managing the organization. Meaningful communication needs the cognitive organizational reorientation to manage the organizational strategies. According to Mckinney Smith (2004), communication is an important part which impacts the performance of the team in the organization. The organization which understands the importance of the communication is able to manage the daily operations of the business (Pauley, 2010). The communication process in the organization coordinate the factors of the production and human elements for the effective network change. There is the need of effective communication every organization with the new technology that would increase organizational performance (Key ton, 2011). The communication pro cess includes seven steps in the organization i.e. message, encoding, transmitting, receiving, decoding understanding and feedback. Communication in the organization is not a simple task. The communication process within an organization is described below in the figure. Figure 1: Communication Process (Source: Pauley, 2010) Communication in the organization- Based on the research done by Banihashemi (2011), the various channels of the communication are the most effective way to build the relationship with the employees in the organization. So, communication is the basic part for developing the structure of the organization. Communication is the key factor in the organization to maintain the coordination in the various activities at different level in the organization. Now, the communication in the organization can be upward, downward and horizontal. The process of communication is important for the organization to manage the basic functions of the business i.e. organizing, planning, controlling and leading. Communication is also helpful in managing the responsibilities by the managers (Rajhans, 2012). The role of the communication in the business is described below: Communication serves as the motivation by providing information and clarifying the employees about the job roles and the ways to perform the job. Communication process is important to improve the performance of the employees within the organization. Further, communication is basically spreads the information among the organizational members. Communication is also important for the successful decision making process as it is helpful in identifying the alternative course of actions. Communication is helpful in controlling process within the organization. In the organization, there are many levels of hierarchy and various guidelines and principles that should be followed by the employees. Employees should fulfill the organizational policies to perform the tasks effectively. They must communicate the work problems and accusation with the senior management. Thus, communication is helpful in managing the various functions of management (Goris, 2007). Example There are many top companies which are using effective communication process to manage their business process. The famous company Ford uses a number of communication tools to connect people with the business. In the business operations of Ford, communication is most challenging but visual tool. Ford uses bulletins, tools and exclusive newspaper and newsletters. There is the internal newsletter of the company @Ford which is translated in various languages. The communication tool makes sure that the provided messages always stay in peoples mind (Tanwar, 2015). Feedback and its role There are many people in the organization who suffer from the lack of performance feedback. Feedback is the most powerful and most under used management tool which are used by the organization to motivate the employees. Feedback is helpful in bringing the people on track in their job roles. It has effective skills to satisfy the employees and improve their productivity in the organization. By getting positive feedbacks, employees in the organization feel involved and identified. Basically, feedback takes place when an environment reacts on some behavior or action. For instance, it can be related to customers feedback for the companys product, policy or service or it can be employees performance feedback given by the manager for the performance of the employees. Feedback can be both positive and negative. To make important decision in the business operations, feedback can be the valuable information. Top performing companies are able to get higher position in the market because they a re continuously seeking for the ways to make their better to best. The main focus of these companies by the feedback are on the various parts i.e. employees, clients, suppliers, customers, stakeholders and vendors. Effective feedback are beneficial for everyone i.e. for the receiver, giver, and for the organization. There are some reasons which prove that feedback is very important in organization (D'hoedt Bouckaert, 2011). Feedback can take place all the time i.e. at the time of employee survey, training evaluation, and performance appraisal. At every time, a person can say to the person, customer, employee, vendor etc. Basically, people communicate feedback in the organization. Feedback has the ability to motivate the employees to perform better in the job role. By getting feedback on the performance, they feel appreciated and valued within the organization. The feedback from the suppliers, clients, customers, stakeholders and vendors, employees can be motivated to build up better working relations in the society. Further, feedback can be effective tool in improving and managing the organizational activities and operations. Continuous feedback is crucial for the entire organization for creating strategies; developing products, stay connected with the goals, improving relationship, improving services and much more. Sometimes, feedback is considered as the criticism and negative criticism is not good for organization. But the best and positive feedback can be helpful in formulating and taking better decisions to increase and improve the performance of the organization. Now, there are many researchers who have stated that the feedback is the important part of the communication. It is the link or component in the communication cycle as it indicates the successful spread of the message. So, effective feedback is interactive, active and able to improve the performance of organization. Feedback can be time consuming, difficult and repetitious when the performance of the organization and its employees is poor. Feedback has the most positive impact in the organization. To maintain the good working relationship between the organization and staff, Feedback is important. The importance of building relationship is based on the trust, collaboration and mutual respect. There is the process in obtaining useful feedback in the organization. Figure 2: Feedback process (Source: Torokoff Mets, 2005) There are three steps in the feedback process i.e. organization of observation and feedback, content and delivery feedback and use of feedback in learning process. So, it is clear that the various feedbacks are very helpful in improving the performance of the organization and managing the organizational activities (Torokoff Mets, 2005). Example Feedback process is used by the company PepsiCo which is the second largest food and Beverage Company. The company is using 360 feedback programs to maintain its leadership population in the global market. To improve leadership, the company has adopted four programs i.e. 360 processes, an employee survey, upward feedback process and a personality instrument. These four processes are important to work together in the company. Conclusion This essay describes the importance of feedback and communication in managing the organization effectively. From the above discussion, it is observed that communication and feedback can be considered to be the important part of the organization for managing the organization effectively. Communication is an important tool part of the organizational activities as there should be the positive attitude among the employees towards managing the organization. There is the need of effective communication every organization with the new technology that would increase organizational performance. The process of communication is important for the organization to manage the various activities of the organizations to improve the reputation in organization. Now, in terms of feedback, it is observed that feedback is helpful to guiding the people so that they can do the best in their job roles by motivating and energizing them. To make important decision in the business operations, feedback can be th e valuable information. Thus, it can be said that feedback and the communication process is important to manage the organization as they motivate the people of the organizations to perform bets in their job role.
