Sense Perception Essay Example for Free

Sense Perception Essay Maurits Corneluis Echecher (1898-1972) is one of the most famous graphical artists. He used to use maths in his art to trick peoples senses. Some of his paintings are used for atmosphere ideas in movies, for example inception. Magicians also play with our senses and trick us. The method they use is known as smoke and mirrors. The expression smoke and mirrors has now entered our everyday language in English it refers to deceptive behaviour, actions or information. What does red mean? Love, dangeretc. But it can also be a corporate symbol (vodaphone), a political symbol (like communist flag) communists were called the reds. Red can also be an artistic symbol, symbol of danger, sports team, red can take the significance of health (red cross). Iconoclastic when you cannot have use any religious symbols, like in Islam. In the mosque there are no statues, just quotes from the Koran. Whenever we perceive something the meaning changes depending on the context, the meaning depends on the context. What makes up this context ? * The history of the people. * The culture of the people. * The political views of the people. * Emotions. * The environment surrounding us (if were in a museum, class etc.) John Locke was the founder of the school of Empiricism he said that the human mind is born as a tabula rasa (clean slate). He believes we are born with nothing and no skills, he thinks that we gain ideas, skills and knowledge throughout our lifes. This means that context that provides the meanings to the things we perceive is not something were born with, but something we learn. Gestalt psychology (school of thought), it argues that we shouldnt understand perception as an individual phenomena, but as a whole because the result is more than the part of it. This theory may be applied to many things ex. a movie or a painting. This applies to the way we interpret other individuals and human actions, this is what we call social perception. Social perception is also related to the we dress up. Social perception also leads to racism, think of Germans and Jews.

Poetic Wordplay Essay -- Poetry Analysis

One of the recurring themes within Manyoshu, a collection of over 4,000 poems (Keene 1955, 33) written by a variety of authors—some of whom were emperors and their paramours—is love and the coping with the loss of one’s love. The very nature of the Manyoshu lends itself to this subject matter, particularly since many of the poetic works contained within are tankas that are highly symbolic and suggestive of association. As such, many of the poets found within this work utilized various literary devices to express their notions of love and its absence, some of the most important of which include diverse aspects of diction, anaphora, alliteration, and other forms of sentence structure. There is a definite proclivity of the structure of a poem influencing and coloring its content, particularly due to the utilitarian aspects of much of the literature that comprises Manyoshu. Many of these poems were also regarded as songs that would be stated or sung aloud during impo rtant rituals to utilize a spiritual aspect of the words and the sentiments they conveyed. Therefore, when discussing the topic of love and its loss within this compendium, it is important to understand that specific choices of words are highly influential in conveying the desires and feelings of both the poets and their poems. Numerous examples abound in which one can see how the diction of a poem helps to impart a particular meaning, especially when the thematic issue of that poem has to do with love. Oftentimes, much of the poetry within Manyoshu—which is the oldest known work of poetry written in Japanese (Morrow 2004)—treats of unrequited feelings of passion between individuals, such as the verses composed by Empress Iwa no Hime, who was romantically involved with Em... ...h is why so many of the poems in this volume deal with the haunting memory of a past relationship that a poet is clinging to through his or her writing.

Lab Report Mn-Steel

Determination of Manganese in Steel Submitted by: ——————- Date of Submission: 27. 03. 11 Objectives: In steel production aside the iron, which is the primary source, some amounts of manganese is used together with carbon. The objective of this experiment is determining the manganese amount in the steel compound by using UNICAM UV-VIS Spectrometer. Theory: Many molecules absorb ultraviolet or visible light. The absorbance of a solution increases as attenuation of the beam increases.Absorbance is directly proportional to the path length, b, and the concentration, c, of the absorbing species. Beer's Law states that A = ebc, where e is a constant of proportionality, called the absorptivity. Different molecules absorb radiation of different wavelengths. An absorption spectrum will show a number of absorption bands corresponding to structural groups within the molecule. In this experiment wavelength range between 400-650nm is used in order to detec t in the visible range. Steel is an alloy primarily composed of iron with carbon content between 0. 2% and 1. 7% by weight. 1. 5% manganese is may be used too, to provide additional strength for a modest price increase. Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Manganese is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. In order to detect the manganese amount in the compound KIO4 is used to oxidize Mn+2 to Mn +7 since Mn+2 does not absorb in the visible region therefor cannot be detected.Tungsten lamp is used in the experiment to reach the range between 400-650nm. After the beam comes from the tungsten lamp, it passes through the monocromator to reach the wavelength range which was selected to find the maximum wavelength. After the light passes through the monocromator it goes through the cuvette and then the detector. The cu vette is made of quartz in order to pass the visible light whereas a glass cuvette would absorb it. The Redox Reaction: 5 IO4 – + 2 Mn2+ + 3 H2O ? 2 MnO4 + 5 IO3- + 6 H+ Reagents: KMnO4 KIO4 H3PO4 Unknown SolutionDeionized Water Apparatus: Pipette Beaker Heater UNICAM UV-VIS Spectrometer Quartz Cuvette Volumetric Flask Calculations: Weight of KMnO4 : 0. 09149g Weight of KIO4 : 0. 40807g emax: 525nm Absorbance for the unknown: 0,415 [pic] Conclusion: I: Qualitative and or Quantitative identification II: Error discussion While at the addition step of H3PO4 after 5ml of H3PO4 is pipetted, it was transferred into a volumetric cylinder, and then transferred into the unknown solution and the blank solution. There may have been material loss during the process.Dilution errors may have been done during the dilution process. There may be some personal errors made while weighing the compounds Any scratch, stain or fingerprint left on the cuvette may cause a shift from the accurate wave length in the detected value. If any bubbles left in the cuvette while the detection is made will as well as cause wrong wavelength value.

Essay on The Misconceptions of the American Agriculture...

Have you ever thought about what the world would be without Agriculture? Have you thought about going to the meat department of your local grocery store and there is no meat, but vegetable substitutes? The same people that are telling you that soy is an appropriate alternative to meat, have never been on a farm, and wouldn’t know the first thing about it. There are many organizations that lie to the American public each day to fulfill their self centered agendas. The organic sub-culture is gaining more popularity than ever, with their lies and false propaganda on topics as, herbicides, pesticides, land erosion, hazardous waste, steroids and medicines. Despite the lie’s and misconceptions, the agricultural industry is one†¦show more content†¦Most of the members are high school students, but many members are at collegiate levels. Another youth organization is the 4-H organization. The 4-H is a community of young people across America learning skills such as, citizenship, leadership, and lifelong skills. 4-H pro grams have three main goals: Science; Citizenship; and Healthy Living. The 4-H organization mission is to educate youth in arts, and sciences and also to encourage fellowship with service opportunities. With the continued urban expansion, 4-H continues to plan new projects for its members to study beyond agriculture and animal science, including, photography, conservation, cooking, public speaking, shooting sports and other skills. The 4-H is often associated with its summer camps, county fairs and large state fairs. 4-H has spread its philosophy to an international youth audience, and regularly awards and sponsors the 4-H trips and cultural events. The 4-H club currently has about 6.5 million members across America. Even though we’ve been educating our youth for many years, there is a small group of people that make their living attacking the United States Department of Agriculture. Misconceptions are often created by groups with an anti-agriculture or anti-animal agriculture agenda.
