The Composition and Properties of Glass

When you hear the term glass you may think of window glass or a drinking glass. However, there are many other types of glass. Glass is the name given to any amorphous (non-crystalline) solid that displays a glass transition near its melting point. This is related to the glass transition temperature, which is the temperature where an amorphous solid becomes soft near its melting point or a liquid becomes brittle near its freezing point. Glass is a type of matter. Sometimes the term glass is restricted to inorganic compounds, but more often now a glass may be an organic polymer or plastic or even an aqueous solution. Silicon Dioxide and Glass The glass you encounter most often is silicate glass, which consists mainly of silica or silicon dioxide, SiO2. This is the type of glass you find in windows and drinking glasses. The crystalline form of this mineral is quartz. When the solid material is non-crystalline, it is a glass. You can make glass by melting silica-based sand. Natural forms of silicate glass also exist. Impurities or additional elements and compounds added to the silicate change the color and other properties of the glass. Glass Examples Several types of glass occur in nature: Obsidian (volcanic silicate glass)Fulgurites (sand that has been vitrified by a lightning strike)Moldavite (green natural glass likely resulting from meteorite impacts) Man-made glass includes: Borosilicate glass (e.g., Pyrex, Kimax)IsinglassSoda-lime glassTrinitite (radioactive glass formed by heating of the desert floor by the Trinity nuclear test)Fused quartzFluoro-aluminateTellurium dioxidePolystyreneRubber for tiresPolyvinyl acetate (PVA)PolypropylenePolycarbonateSome aqueous solutionsAmorphous metals and alloys

`` Beloved `` By Toni Morrison - 2097 Words

â€Å"Beloved† by Toni Morrison is a historical/fictional novel that deals with the idea of the supernatural and the repercussions of slavery towards a society and the individual persona. The novel explores the wreckage slavery brings upon its characters in all senses of the self. They have been freed from slavery but the psychological trauma endured remains constant; leading them to do the unthinkable. In the novel Morrison utilizes the character of Beloved to represent the ghost of slavery in an entire community. As we learn about the community we come to understand that they are haunted by their past because they refuse to accept it. Most importantly we realize that slavery has led the characters to become completely desensitized with their individuality and sense of self. Yes, they are physically free of slavery, but mentally they are still enslaved. The novel exemplifies how hard it is for the characters to re-discover their sense of self and their own worth. Only thro ugh individual and communal healing, are they able to achieve the prior. The story is set in 1873, numerous years after the abolition of slavery, taking the reader through flashbacks and back without warning.

Body Image vs. Self Esteem - 1565 Words

BODY IMAGE VS. SELF-ESTEEM According to Merriam Webster’s Dictionary, diet is food and drink regularly provided or consumed. It is also defined as the regimen of eating and drinking sparingly so as to reduce one’s weight. The latter definition will be the one used for this research paper. Currently, up to fifty percent of women have tried dieting at some point in their lives and at least 90 percent of teenagers diet regularly. Due to this, the â€Å"diet fad† is worth billions with its government, pharmaceutical, and weight loss agencies funding it. Americans alone spend more money on weight loss programs and products than any other nation. People go on diets for a number of reasons. One reason is their concern for their health. Many†¦show more content†¦When success gets the majority of the ratio, a person feels good about him/herself. A poor body image is classified under failures. In turn, self-esteem is hindered greatly by poor body image. There is a thin line between body image and self-esteem but one greatly affects the other. Body image becomes a major factor in having a high or low self-esteem. In improving your body image, you are unconsciously creating an â€Å"ideal self.† According to Brennecke (1978), â€Å"as we gain more experience with life, we begin to develop an image of what we wish to be: our ideal self.† He also stated that this is largely affected by culture, family, friends and media. In many cases, our ideal self can be unrealistic and hard to attain. These high expectations cause people to fall short on their image. As stated above, people usually prefer dieting as their key solution to improve their body image. Based on personal interviews, people are not always happy with the results of their dieting. Most of them are tempted by the food they try to avoid. Some of them don’t get contented with the results because it wasn’t what they were aiming for. This is because dieting is tricky.

It would mean a process of gaining such knowledge and experience as would help us to cope with the challenges that life throws at us and to find ways of enhancing our own existence, as well as that of as great a portion as possible of all the other occupants of our planet. To put it in another way, the highest form of learning would be that which makes us caring and responsible citizens of this world, and equips us with the intellectual means necessary to translate our concerns into specific deeds. Surely such a view of learning is in harmony with the idea of education as conceived in the motto of Hong Kong University – Wisdom and Virtue. One hundred years of furnishing the world with young people who have been provided with the capacity to think independently, to express those thoughts cogently, and to use them for the betterment of our world is an achievement of which this University can be justly proud. We will write a custom essay sample on Aung San Suu Kyis Speech or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The hopes of its founding fathers have been more than realized. At the foundation laying ceremony Sir Frederick Lugard hoped that the graduates of The University of Hong Kong would exert an influence which will be immeasurable in the future among the 400 millions of China’s population. Little could he have envisaged such an institution as this one of today, internationally renowned and one that attracts students from all over the world, who will one day exert an ever-widening influence on the future of more than just one country. As I contemplate the achievements of Hong Kong University, I am filled with deep admiration and also, it has to be admitted, with wistfulness. Whenever I consider the educational progress that has been made in other countries, I think with sadness of the deplorable state of education in my own. There was a time when educational standards and institutions in Burma were viewed with respect and envy by many countries in Asia and elsewhere. Rangoon 1 University, ten years younger than Hong Kong University, is the outcome of the amalgam of Rangoon College and Judson College, the Baptist college. The University rapidly became the breeding ground not only of bright young intellectuals, but of dedicated nationalists determined to free their country from colonial rule. Even as academic standards grew robustly and gained the recognition of long established institutions in the Western world, so did the patriotic fervor of the students gained new momentum. Rangoon University became the vanguard of movements demanding equality and justice and, eventually, these movements were supported and joined by students from Mandalay University, and from schools all over the country. The close link between political movements and universities became an established tradition in Burma. When the country fell under military rule, students were among the first protesters calling for the restoration of democratic rights. As authoritarian rule tightened its grip on the country, the position of universities as institutions aimed at fostering freedom of thought, expression and association was steadily eroded. Yet, after more than two decades of totalitarian governance, it was again the students of Rangoon University who led the movement to free the country from military administration. This was the famous public uprising of 1988. Now, more than twenty years on, the aims of democracy and human rights, for which many students sacrificed liberty and life, have not yet been realized. In the meantime, the standard of education at all levels has fallen and Burma is a country crying out for the potential of its people, especially its young people, to be realized. I might mention here that many leaders of the 1988 student movement still remain in prison today, serving unbelievably long sentences. Education should be available to all, not just to a privileged few. Education should foster values that will promote human dignity and guide human progress in a positive direction. Education should be a true learning process, not a machine for churning out meek, obedient people incapable of reasoning why justice and liberty should not be the birthright of all human beings. I congratulate The University of Hong Kong on its achievements on the human front as well as on its solid academic credentials, which have made it one of the most respected institutions in Asia. I look forward to a closer cooperation with both the faculty of the University, as well as with the student body. I am confident that the day will come when we in Burma will be able to enjoy the fruits of real education and to share them with the rest of the world. This will be the day when wisdom and virtue will triumph. 2
