Arthur Bruce McDonald Essays - Physics, Particle Physics, Neutrinos

Arthur Bruce McDonald Arthur Macdonald is a Canadian astrophysicist. Born August 29, 1943 in Sydney, Nova Scotia, he obtained his Master of Science degree from Dalhousie University in 1964 and shortly after received a PhD from the California Institute of technology. He is currently the director of the Sudbury Neutrino Observatory Institute. He is most famous for proving neutrinos have mass. He did this by showing experimentally that they oscillate between different types of neutrinos (electron, muon and tau). After knowing that neutrinos oscillate though different types it is easy to show that they have mass: If they didn't the neutrinos would travel at the speed of light and wouldn't experience time (according to relativity). If this was true they wouldn't be able to oscillate between states, therefore they must have mass. He did this work in the Sudbury Neutrino Observatory, a facility located 2.1 km underground made to solve the solar neutrino problem, which it did. The results he obtained from working there were of 5 significance meaning a chance of statistical error are smaller than 1 in a 1 000 000. He was awarded the Nobel Prize in 2015 for that work (it was shared with Professor Takaaki Kajita). His contribution to society was the advancement of human knowledge, doing science for the sake of science itself. In his own words " " We are very satisfied that we have been able to add to world's knowledge at a very fundamental level." He now holds the Gordon and Patricia Gray Chair in Particle Astrophysics in Queen's University.

Arab Views of Europeans 1578-1727 Essay Example | Topics and Well Written Essays - 1500 words

Arab Views of Europeans 1578-1727 - Essay Example And given the fantasy and the Orientalism that marked early modern and modern European perceptions of Arabs and Muslims, did Occidentalism evolve in Arab-islamic thought? Did the military polarisation that marked the two shores of the Mediterranean produce an Arab fantasy and invention similar to that characterising a large amount of Europeans about Muslims. (p. 127) From the start, Matar have recognized that majority of the historians and scholars believed that the degree of interest of the Arabs and Muslims in Latin Christendom is significantly lower than what was shown by the Europeans in the Far East. He pointed to two prevailing schools of thought that explain this attitude: First, the Europeans are generally viewed as barbarians because of their heathen religion that teaches a theology, which, according to Quran, is false and distorted; Second, the European society has been seen as inferior to the Arab world because of the Muslim belief that the heritage of the Middle Ages have given them the edge over the Europeans. The corpus of the Islamic literature on the subject has shown a degree of hostility towards the West which clouds the existing curiosity over the other civilization. This hostility would further grow as the West asserted its hegemony in the course of its colonisation efforts. Matar, however, added an interesting insight to this variable. According to him, the disinterest, as has been comprehensively illustrated by the various sources, permeated in the Ottoman territory and those within the reach of its influence. He cited the case of Morocco, Tunisia and Algeria who, in their history and literature, have spoken about the Europeans quite extensively, displaying a level of interest that is unprecedented elsewhere in the Islamic world. He took note of the fact that the Moroccan elite were educated and have in their disposal a high level of literacy that have made up with the lack of printing machines that could have made the mass production of

Lord Of The Flies - Discovery :: essays research papers

Lord Of Flies( The Importance of self-discovery) 1Human should understand the importance of self-discovery. In the Lord of the Flies, Ralph, Simon and Samneric learned the weaknesses and darkness within the human hearts. People grows up when they faces a challenge. Ralph ‘s challenge is how to be a good and responsible leader. Simon’s challenge is how to speak at front of people. Samneric’s challenge is how to make right choice. The truth about self-discovery may be cruel, but it is worth to learn from it. 2Ralph is being a playful, innocent child in the beginning of the story, but towards the end he matures significantly. Excluding Piggy, Ralph is the most mature and responsible member of the boys, for he is concerned throughout the book with keeping the fire on the mountain going, and building shelter. " If a ship comes near the island they may not notice us. So we must make smoke on top of the mountain. We must make a fire." pg,37 Ralph always has the strong belief that all the children will be saved from the island sooner or later, but at middle part of the story he begins to doubting it. At end of the story, after the death of Piggy, Ralph’s encounter with the Lord of the Flies, he knocks over the pig’s skull. " A sick fear and rage swept him. Fiercely he hit out at the filthy thing in front of him that bobbed like a toy and came back, still grinning into his face, so that he lashed and cried out in loathing." pg206 Ralph realize the evil is part of him and just as to other boys. However, he is the only person who acknowledges the importance of being responsible, and he takes over as a true leader even though he is not necessarily good at it. 3Sam and Eric represents the crowd in modern society, just like every ordinary human. They are faithful and mostly good. They can be described as loyalist in the story. Their rule is to serve whomever is the leader. For example when Jack says " Grab them! No one moved. Jack shouted angrily. I said " grab them"! " Samneric finally give into his threats on their travel to Castle Rock. Later, then betray Ralph, by showing his hiding place to Jack. " You’re sure he meant in there? The twin moaned faintly and then squealed again. " " He meant he’d hide in there?" pg. 214 In this way, Samneric symbolize the weakness of human nature. They have lose any real sense of loyalty to others.
