The Effects Of Melting Glaciers On Canada s Coastline Essay

1.0 INTRODUCTION This problem could mark either the end of human civilizations or mark the beginning of the next era of human development. It would decide on our species survival, whether there will be another mass extinction like the one 65 million years ago. The question is â€Å"How might the breaking up and melting of continental ice in Greenland and the Antarctic affect Canada’s coastline?†. In the following sections, we have gathered an abundance of information from a variety of sources from which we will discuss, and analyze. We will find out how this data can help us understand the effect of melting glaciers on Canada’s coastline, as well as how and what we could do to stop or slow it down. 2.0 ISSUE OVERVIEW The breaking of continental ice from Greenland and the Antarctic has been slowly breaking off and melting for a long time. The continental ice which has broken off melts faster and faster as it drifts towards the equator, eventually deposing all the fresh water ice into the ocean. This process, which would slowly drown the coastlines of the entire world, including Canada, is very dangerous for the survival of human civilizations. Due to Canada’s larger and more exposed urban coastal regions, it will suffer a harder blow than most other countries. Islands like Prince Edward Island, Newfoundland, and Nova Scotia will be hit particularly hard, losing a lot of its farmland and coastal towns due to the melting and breaking off of continental ice.

Solar Energy- The True Power of the Sun - 687 Words

They say the greatest thing about our Universe is its ability to produce certain renewable energies which is then used by humans. There are numerous amounts of renewable energies found in the world. The sun, wind and tides in the oceans are just some of the many kinds . The sun alone does so much in the environment that may sometimes go unnoticed. its one of the many things some humans take for granted. Humans use the sun for various reasons, to tan on the beach, or even for their basic vitamin D. The sun triggers photosynthesis in the chlorophyll molecules of green leaves , a reaction that produces carbohydrates which is initially the basis for all terrestrial life. Scientists’ say it takes millions of years for the energy found in the sun’s core to reach the solar surface, following that it takes a bit over eight minutes to travel the 98 million miles to earth. The amount this solar energy travels to earth is approximately the speed of 186,000 miles per second, measu red in the speed of light (Telstar.ote.cmu.edu, 2014). The sun is amazing itself, it provides so much for the living organism on planet earth and the most important energy formed is solar energy. Solar energy is also the strongest/ most powerful of all renewable energy resources in the world (Writer, 2014). The sun is the initial producer of Solar energy.

How does Alan Bennet create sympathy for the character of Wilfred in Playing Sandwiches Essay Example For Students

How does Alan Bennet create sympathy for the character of Wilfred in Playing Sandwiches Essay This essay sets out to find how a playwright, ie Alan bennet, extracts sympathy from the audience for his character. Alan Bennet is an expert at creating sympathy for his characters. He places them in situations or with problems which become the focal point of his drama. Wilfreds character is that of a paedophile, but Wilfred also has a nice personality and is not the stereotypical monster that you would associate with his problem. So how does Alan Bennet create sympathy for a man who has created a tragic crime and would normally be rejected. When you read the title of the essay the title you will ask your self is what is Playing Sandwiches. Well, it is the title of play written by Alan Bennet Playing Sandwiches is also a monologue. The main characteristics of a monologue that sets it part from any ordinary piece of drama is, when you view through any medium ie on stage, television,or book it is one person speaking. Another aspect is, there is a quick change between the thoughts of the main character, in this case Wilfred, this is called a stream of consciousness, so ideas lead quickly from one to another but not necessarily in a logical sequence. Alan Bennets first task is to create a character we can understand or relate to. So how does he make Wilfred seem normal, ie someone we can relate to. The first time in the monologue where Bennet does this is in the first paragraph. Wilfred is shown in a park attendant uniform, so he has a job just like an average man, he also starts complaining about the state of the park. Alan Bennet uses, extreme words like filth instead of dirty to create the sense that Wilfred is as disgusted as the audience might be.Character response to the situation is very important, because if the response is completely differently to that which might be expected, then we might start to think of Wilfred as not being normal. Again the idea being to show that Wilfred has many of the normal attitudes and standards as other members of society. Wilfred is also married to Janet which you definitely do not associate with paedophilic tendencies. Bennet also shows Wilfred with friends and family at a social event, a christening, which also builds on the sense that he is a normal part of society. But normally a paedophile would be treated differently, he would be thought of as scum and would be a social out cast, with no friends or a job. But Wilfred is presented completely differently, he has a number of attributes which a paedophile would not be expected to have, a wife being perhaps the most important difference. Another thought that comes into peoples minds when you think of a paedophile is, monster. This is perhaps the reason why Alan Bennet needs to make Wilfred seem normal, because it would be difficult to sympathize with a monster. So Alan Bennet has managed to make Wilfred somewhat normal, so that a link is formed between Wilfred and the audience. The next step for Alan Bennet is to build up sympathy between the audience and the character of Wilfred. Bennet is often very subtle at this, most of the time, but on occasions he develops situations or scenes which demand a higher level of feeling. One example of Bennets subtle approach occurs when Rosalie is clouted for suggesting that Wilfred be a godparent. Alan Bennet again makes use of vocabulary to its fullest effect, because the harsh words emphasise the embarrassment for Wilfred. As a result we are made to feel sorry for him. Another important subtle moment of sympathy develops when his family makes fun of him. The dramatic device here is to use the other characters to show Wilfred as the outcast and underdog and as such make him appear vulnerable, the effect is again that we are made to feel sorry for him. The effect this has on the audience is the creation of contrasting characters, which gives us an alternative perspective on Wilfred. Here we sympathise because they are teasing a character that we know more closely. 'I wanna be yours', 'To His Coy Mistress' and 'Our Love Now' EssayThe judge said i would get treatment. I havent been given any treatment. Theyve put me by my self to stop me getting the others giving me the treatment. The scalded in the kitchen treatment. The Piss in the your porridge treatment Bennet also stirs up a social context here by suggesting the other prisoners are wrong to feel they have the right to punish another prisoner, because they feel his crime is worse than their crime. Thus we sympathise with Wilfred for getting unjust treatment or harassment. Wilfred also says in this scene, Its the one bit of my life that feels right and its that bit thats wrong. In this powerful soliloquy, we sympathise with Wilfred as he confronts this cruel realisation. Wilfred has a desire to be alone and isolated, this is use of soliloquy and dramatic irony. We sympathise because we realise that it is too late for him. The damage is done. Also it is ironic that he is totally isolated and alone but it is not the way he would prefer. Wilfred is seen in despair as well in the very end stage direction, the use of fade and use of vocabulary all play their part in a memorable ending. The fade here emphasises the isolation as Wilfred is engulfed in darkness. Alan Bennets stage directions leave the audience with the harrowing sound of Wilfred crying. A very difficult situation not to have sympathy for. AB has succeeded in creating sympathy for Wilfred, by firstly developing Wilfred to have similar emotions and feelings to yourselves therefore making him seem normal and easy to relate to. He then throughout the monologue builds on the sympathy we feel for Wilfred and then secures it in the last scene with a powerful and moving ending to the play which gives the audience a lasting impression of Wilfred to think about afterwards. AB uses this monologue to contrast the man against the crime, i.e. you get to know Wilfred before knowing the crime therefore you see the human behind the inhuman acts. This is also what Bennet is suggesting about the police, social services and the other poisoners because all they could see is the crime, not the man behind them.

Psychophysics Essays - Psychology, Cognitive Science, Neuroscience

Psychophysics An Approximate psychological law relating the degree of response or sensation of a sense organ and the intensity of the stimulus. The law asserts that equal increments of sensation are associated with equal increments of the logarithm of the stimulus, or that the just noticeable difference in any sensation results from a change in the stimulus, which bears a constant ratio to the value of the stimulus. Ernst Heinrich Weber (1795-1878) Weber was the first German anatomist and physiologist to introduce the concept of the just-noticeable difference, which is the smallest observable difference between two similar stimuli. From 1818 until 1871 Weber was a professor at the University of Leipzig. Weber is best known for his work on the sensory response to weight, temperature, and pressure. Weber stated that, in order for any increase in the intensity of the stimulus a threshold of sensation must be passed. This increase would create the just-noticeable difference. The ratio Weber discovered was the total intensity of sensation, rather than an absolute figure. Greater weight had to be added to heavier objects in order for the person to notice the change. Weber's observations were formed mathematically by Gustav Theodor Fechner, which he later called Weber's law. Gustav Theodor Fechner (1801-1887) Fechner was a German physicist and philosopher; he was an influential figure in the development of psychophysics. He was concerned with the quantitative relations between sensations and the stimuli producing them. When Fechner was 16, he began medical school at the University of Leipzig where he studied anatomy under Weber. Fechner upon graduation discovered his interested lead more toward physics and mathematics than medicine. Fechner by the end of the 1830's had written several papers on the perception of complementary and subjective colors. In 1840 his article on subjective afterimages was published. The same year he suffered a nervous collapse. Fechner had to quit his job at the University due to his temporary blindness from staring at the sun during his experiments. He returned in 1848 he completed when Nanna, which is a metaphysical treatise that explains the philosophical treatment of relationship of mind to body. This left a future program for psychophysics by linking increased bodily energy with an increase in mental intensity. From 1851 and 1860, Fechner worked on his psychophysical methods: just noticeable differences, right and wrong cases and average error. He also did experiments on visual distance and brightness. Fechner also lifted weights that lead to the first two volumes of the Elemente der Psychophysik. The Elemente der Psychophysik was to distinguish an exact science between physical and mental phenomena. The relationship between sensation and nerve excitation was known as the inner psychophysics. The outer psychophysics was referred to as the relationship between sensation and physical simulation. He developed his famous principle: the intensity of a sensation increases as the log of the stimulus (S = k log R) to characterize outer psychophysical relations. Fechner believed this was demonstrating a fundamental philosophical truth: mind and matter are simply different of conceiving of one and the same reality. The philosophical message of the Elemente was widely ignored while; its orderly and practical contributions were not. Fechner was a well trained, rational experimentalist and a skillful mathematician and the influence of his work on scientists was accurate. Terms of physical events could be linked to the measures of mental events. Fechner showed the potential for quantitative, experimental exploration of the phenomenology of sensory experience and established psychophysics as emerging scientific psychology. I decided to write my paper on psychophysics because I really do not know much about it. The article I read was very interesting. Denis Leri the author of The Fechner Weber Principle asked a few questions at the beginning of her article. In bright midday sun you light a candle. Does anyone notice it getting brighter? I would have never thought the candle would make the outside brighter. Will you identify my voice if I call you on a cellular phone at a rock concert? I do not think I could pick out a familiar voice because the noise level would be too loud. If you are carrying a refrigerator up a flight of stairs and someone puts a hammer on it do you notice the difference? I would have said the weight of the hammer would have made a difference. After reading this article I would now say the ratio between the hammer and the refrigerator is greatly different and would not cause a noticeable difference. I found psychophysics pretty interesting and I plan on reading more about it. Bibliography The Fechner Weber
