Theories Of The Origin Of The Moon :: essays research papers fc

The Moon is the only natural satellite of Earth. The distance from Earth is about 384,400km with a diameter of 3476km and a mass of 7.35*1022kg. Through history it has had many names: Called Luna by the Romans, Selene and Artemis by the Greeks. And of course, has been known through prehistoric times. It is the second brightest object in the sky after the Sun. Due to its size and composition, the Moon is sometimes classified as a terrestrial "planet" along with Mercury, Venus, Earth and Mars. Origin of the Moon Before the modern age of space exploration, scientists had three major theories for the origin of the moon: fission from the earth; formation in earth orbit; and formation far from earth. Then, in 1975, having studied moon rocks and close-up pictures of the moon, scientists proposed what has come to be regarded as the most probable of the theories of formation, planetesimal impact or giant impact theory. Formation by Fission from the Earth The modern version of this theory proposes that the moon was spun off from the earth when the earth was young and rotating rapidly on its axis. This idea gained support partly because the density of the moon is the same as that of the rocks just below the crust, or upper mantle, of the earth. A major difficulty with this theory is that the angular momentum of the earth, in order to achieve rotational instability, would have to have been much greater than the angular momentum of the present earth-moon system. Formation in Orbit Near the Earth This theory proposes that the earth and moon, and all other bodies of the solar system, condensed independently out of the huge cloud of cold gases and solid particles that constituted the primordial solar nebula. Much of this material finally collected at the center to form the sun. Formation Far from Earth According to this theory, independent formation of the earth and moon, as in the above theory, is assumed; but the moon is supposed to have formed at a different place in the solar system, far from earth. The orbits of the earth and moon then, it is surmised, carried them near each other so that the moon was pulled into permanent orbit about the earth. Planetesimal Impact First published in 1975, this theory proposes that early in the earth's history, well over 4 billion years ago, the earth was struck by a large body called a planetesimal, about the size of Mars. The catastrophic impact blasted portions of the earth and the planetesimal into earth orbit, where debris from the

Would Life Still Be Meaningful in the Absence of an Afterlife?

When people ask about the meaning of their lives, they are more likely concerned as to what worth would their actions be on Earth if there is no specific end to the road that they travel on. Being inherently inclined to the material, Man always seeks reward for everything that we do in our lives. As children, we almost always seek to excel in class in order that we can have the persuasive power to ask our parents for the different goods that we have laid our eyes on. This is human nature, and our nature always invades into our train of thought.   â€Å"What would I get for doing this?† would be the collective question that permeates our minds if we think about the meaning of our lives. To them, the meaning of life is the material end which they believe their individual actions would entitle them to. People seek something tangible, something that can be felt, in determining the meaning of life. Some are also driven by their sufferings, their negative experiences, in questioning why they are here. They want to know to what purpose have they been born into this world, and why do they have to suffer that way. To them, the meaning of life is an answer, a reason that will explain the things that happen to them throughout their lives in this world. I believe that the question about the existence of the afterlife is detrimental to one's quest to finding meaning in his existence. Instead of finding the true value of our lives, we are now preoccupied with how we should act in order to attain the afterlife, and inevitably forget about the fact that we should be living as meaningfully as we could in this world that we have been born into. People, especially those who have found themselves in suffering and in great emotional pain, view the afterlife as a form of escape or a greener pasture that they believe awaits them if they play their cards right in their present lives. However, if we take away that notion, would life for us still be meaningful to live if there is no clear end to which we could direct our efforts to? II. The True Meaning of Life For me, life can still be meaningful despite the apparent absence, or lack of proof thereof, of the afterlife. From my point of view, the afterlife is a figurehead, a symbolic figure, perhaps created by the ancients to address man's question as to the meaning of his life. It is more of an abstract idea rather than a specific â€Å"life† by itself. I define the afterlife for its simplest meaning: â€Å"to live after we have died,† not an exact place that the supposed soul goes to after death. I believe that the idea of â€Å"going to Heaven by doing good† is made especially to cater to man's materialistic nature that everything he does should be given a reward. Obviously, man has been created with a reason. Each of us has a reason, maybe a mission, in this world that we have been born into. Unless we ascertain what that is, we obviously cannot find the meaning for our existence here on Earth. We will continue to ask ourselves why we are still here. But how can we find that answer? Perhaps, the famous adage â€Å"no man is an island† is what I'll consider the most apt and summarized answer to the question of â€Å"Why are we here?† Man exists for the sake of his fellowmen. We are made for the service of each other. That is what man should live for: the good of his fellow human beings and not himself. Every action that we take should be decided with the well-being of our fellowmen in mind, and not just ourselves. The key to finding meaning to our earthly lives is to start shedding our selfish human nature and start living for our fellows. Man's suffering in this world is brought about by his earthly desire to preserve his own self, his discontentment and his desire to hoard all good things in this world for himself. The more material things Man receives, the more he desires, and the more he feels empty because not all things in this world are achievable. Leading such life is meaningless, for there is no point in that life that man can say that his purpose in living has been fulfilled, that he has found his reason for existing. One would probably argue that the key to self-fulfillment and happiness is to achieve all that we have longed for, definitely including money. However, that is materialism, and anything material is temporary and empty. The feeling is passing, and leads to more emptiness and questions, leading to emotional suffering and discontentment. Like Epicurus said, â€Å"the wealth required by vain ideals extends to infinity.† I, for one, would not be able to find happiness even if I had the power to buy everything that this world could offer and money could buy, because there will always be something better than the ones we have. With endless supply of money perhaps, I would be able to buy those things that I could lay my eyes on. However, I still would not be satisfied because then I find something I do not have, and will then long for it again. The process will go on and on until I find that there is no end to the material wealth that the world offers. When we die, all the material things that we have worked for will not go with us to the grave. Materialism is human nature, and like I said, we should overcome human nature if we are to start finding the meaning of life. If I spend my life entertaining every material and carnal urges that I would find, I would be living in vain because in the end it will all come down to nothing. In finding the meaning of life, we should start looking beyond ourselves and start thinking of what is good for the people around us and ourselves as a whole. This constitutes morality, as one does not learn the value of morality without learning to consider what things would be good for him alone, and what things will benefit both him and the people around. When we are morally upright, we will feel a sense of peace and security. For example, an honest man will have nothing to fear from the law than a dishonest thief will. People might say that honesty is actually subjective because the law has loopholes that can be exploited and bent in ascertaining who is honest from the dishonest, but there is the basic law of morality that we are all governed by. A thief may be able to circumvent the due process of law to his favor, but for the rest of his life he will live in fear that someone will come up with some kind of evidence to implicate him. By then, his life would have been meaningless and without peace, spent in fear of the justice that he has evaded. The time allotted for him to exist in Earth would have been wasted, for instead of cherishing every moment that has been granted to him, he instead spends it in dread and apprehension. III. Conclusion The lack of proof that the afterlife exists will not deter me from finding meaning in living my own life, even if my death is the most definite end of my journey. A life of service through acts of kindness and selfless is, for me, the most meaningful life that I can possibly lead. The greatest fulfillment that I could have for myself is the feeling of peace and contentment that I can attain by being satisfied and being thankful for the things that I have, rather than wasting it trying to own the world and finding no peace in entertaining my material nature. To sum it up, the meaning of my life would be the peacefulness that I would get when I look back at my life when I am in my deathbed, knowing that I have done as little wrong as possible in the time that I have lived on Earth. It is the peace I'd feel in knowing that, in living my life, I have not stepped on anyone's rights and lives for my own gain.                     

Different Methods of Communication - 15726 Words

Different methods of communication 1.0 Introduction Communication can be considered as one of the most important parts of human life that has evolved during the history of our existence. Different methods of communication from smoke signal to sign languages to face to face communication have played an important part in our lives. Rapid development in the technology field caused evolution of electronic communication and we started to develop better and faster tools and methods to communicate with each other. As the result of faster and more effective communication people started to learn about different cultures and regions. Actions or deliverables which took our ancestors weeks if not months to achieve were made possible in hours. It†¦show more content†¦During the BSc course at Royal Holloway, the Information Systems Theory and Practice module team conducted a virtual training project which triggered the interest in this aspect of technology. The project involved conducting research into the potential virtual training market by conducting different surveys. Based on the research the team proposed the best method of delivering virtual training such as the use of video conferencing. The team also had to justify the use of virtual sessions for training instead of using traditional face to face training. To increase profit margin and reduce overhead expenses many organisations in the near future will be aiming to conduct virtual sessions. It is much easier to install the hardware and train people on how to use the equipment, but the main challenge is to monitor and increase the level of human interaction. If the human computer interaction is increased and the participants have more freedom and comfort to carry virtual session the result will increase drastically. It will increase the flow of communication which will result in more sharing of knowledge. The motivation to investigate this field is not only based on the reason that this could be the future for all most all organisations but also on the very interesting topic of human computer interaction. Another motivation to conduct this research is to help to reduce the carbonShow MoreRelatedThe Different Methods Of Communication1073 Words   |  5 PagesIn general, there are two different methods of communication.
