John Dalton

John Dalton contributed a lot towards advancing in chemistry and in physics. His most well known accomplishment was his work on atomic theory. This theory was based on his studies with gases and their reactions with each other. This theory was the most important discovery of its time, leading the way to what we know chemistry to be today. Dalton also is known for Law of Multiple Proportions, and Law of Partial Pressures. Chemistry was not Dalton’s first interest though; he was first interested in the weather and color blindness, after considering law and medicine (wikipedia). John Dalton was born in Eaglesfield, Cumberland, England, on September 6 1766. His family was Quaker; he was a son of a weaver. He joined his older brother Jonathan and ran a Quaker school in Kendal at the age of 15 (wikipedia). The school taught languages, 21 mathematics, and science courses, at one point they had 60 students. Though the school was popular they did not make any money, so for extra income Dalton wrote answers to “ladies questions” in magazines (Blamire). After teaching for a while he considered taking up medicine or law but his relatives did not show enthusiasm for either subject. He then moved to Manchester where he became a teacher of mathematics and natural philosophy at the “New College.” He got this position through a blind philosopher and polymath John Gough; Dalton owes much of his scientific knowledge to Gough (wikipedia). After resigning from teaching, he became a private tutor in mathematics and natural philosophy. He also published works on color blindness; he proposed it was due to discoloration of the liquid medium of the eyeball called deuteroanomaly. He was color blind himself but was later discovered he a less common type called deuteroanopia (wikipedia). During this period of his

Teoria Atomica

...Pontificia Universidad Católica de Puerto Rico Extensión Coamo Teoría Atómica María Isabel Rodríguez Goncalves A00214885 CHEM 117 – Prof. Correa Introducción Cada sustancia del universo, están enteramente formada por pequeñas partículas llamadas átomos. Son tan pequeñas que no es posible tirarle una foto. Estas pequeñas partículas son estudiadas por la química, ciencia que surgió en la edad media y que estudia la materia. Para comprender estos átomos a lo largo de la historia diferentes científicos han enunciado una serie de teorías que nos ayudan a comprender la complejidad de estas partículas. Estas teorías significan el asentamiento de la química moderna. Ya se conocía el átomo pero no del todo. Posteriormente a fines del siglo XVIII se descubren un gran número de elementos, pero este no es el avance más notable. Ya en el siglo XIX se establecen diferentes leyes de la combinación y con la clasificación periódica de los elementos (1871). Actualmente su objetivo es cooperar a la interpretación de la composición, propiedades, estructura y transformaciones del universo, pero para hacer todo esto hemos de empezar de lo más simple y eso son los átomos, que hoy conocemos gracias a esas teorías enunciadas a lo largo de la historia. Estas teorías que tanto significan para la química es lo que vamos a estudiar en las próximas hojas de este trabajo. ¿Qué es una teoría? Es una explicación basada en las observaciones y experimentos.

History in Native Son

...History in Native Son Richard Wright’s novel, Native Son, is a more than one man’s story--it is a piece of American history we can see in this tale of an African American young man in the ghetto of Chicago. Wright makes several statements about the African-American experience through characters and situations. By using realistic details, Wright successfully shows us what life might have been like for blacks in America, specifically in the city of Chicago, during the 1930s. Maybe one of the most prominent factors affecting the American life in Native Son is the Depression. The Depression, or the aftermath of it, is simply seen as a way of life in the ghetto that Bigger and his family and friends live. It is obvious in how Bigger and his family lived. An example of this can be seen in the apartment that Bigger and his mother, sister, and brother share with the huge black rat. According to James Davidson, editor of Nation of Nations, Millions stayed alive by foraging like animals. “In Chicago, people stood at local dumps, waiting for the next garbage truck. When one pulled away from the pile, read a 1932 report, crowd of 35 started digging with sticks, some with their hands, grabbing bit of food and vegetables.” (Davidson, et al. 949) The image of struggling to survive is evident throughout the entire novel. As a result of the Depression, the government offered public assistance commonly referred to as “relief” to those in need. Native Son also shows the existence of...

...we live in a society that is defined as being free and democratic. The Government of Canada works extensively in order to ensure that the country’s laws are regulated and maintained and eventually followed by society. These rules and regulations arrive from the decisions made by the court systems and the government. Politicians are elected by us, the citizens, in order to represent our views on the regulation of certain laws but also assist in taking care of society and the economy by influencing public policies and making critical decisions. Living in a democratic country, these elected officials are expected by society to be honourable and fair when it comes to making decisions that are in the best interests of the community. Premier Dalton McGuinty, however, overlooked this concept when he decided to hold a private meeting behind closed doors with a stakeholder. In 2007, the Ontario Government announced that it would increase the minimum wage of workers every year until it reached the maximum of $10.25 in March of 2010. McGuinty’s private meeting involved a discussion with the stakeholder about cancelling the remaining increases due to Canada’s economic placement. This unethical decision by Premier McGuinty caused an uproar within communities mainly due to the fact that this action did not represent a democratic society. But is democracy the only issue present in this case? How does procedural fairness play a role in McGuinty’s unethical act? The answer to these questions...

Johnny Got His Gun Dalton Trumbo Analysis

...The passage from Johnny Got His Gun by Dalton Trumbo shows a complicated but loving relationship between a father and his son. In the passage, the tradition of Joe and his father fishing together is broken. The father, however, reacts calmly. For eight years, they had gone camping together, preferring each other’s company over anyone else’s. And that year, Bill Harper and Joe were going fishing together. This coming of age tale shows a young man separating from his father and becoming independent, and an abandoned father showing acceptance instead of anger. Through syntax, point of view, and selection of detail, and symbolism, Trumbo creates a complicated and vivid relationship between a father and son. The use of diction and syntax in the...

Rawlsian Arguments

...Forthcoming: 72 Fordham L. Rev. 1857 (2004) RAWLSIAN FAIRNESS AND REGIME CHOICE IN THE LAW OF ACCIDENTS Gregory C. Keating* The political philosophy of John Rawls is pregnant with implications for the tort theory. Our law of intentional and accidental physical injury is rich with the rhetoric of reasonableness and fairness, and these ideals lie at the heart of Rawls’s political philosophy. The figure of the reasonable person is central both to the law of negligence—where it serves as the master criterion of justified risk imposition—and to the law of intentional torts—where it helps to define the contours of permissible self-defense, the sensibility by which the offensiveness of contact in battery is measured, and the content of the consent given in connection with matters as diverse as The concept of contact sports and medical operations.1 reasonableness figures prominently in strict liability as well. The intentional infliction of unreasonable harm triggers liability for damages in the law of nuisance, and strict liability in general can be fruitfully understood as a form of liability applicable when the conduct which leads to accidental injury is reasonable, but the failure to make reparation for the harm done is unreasonable.2 Principles of fairness figure more prominently in the judicial rhetoric of strict products liability than economic ideas of efficient precaution and efficient insurance do.3 * William T. Dalessi Professor of Law, USC Law School. For instruction...

The Age of Enlightenment

...The so-called long Age of Enlightenment in Europe, stretching from the mid-17th century into the 1830s, engendered new political, economic and social ideals and generated knowledge across the arts and sciences. But part of its impetus was outside of Europe. Dorinda Outram likens the European Enlightenment to" a world drama of cross-cultural contact" that "triggered anxieties" for Europeans about the nature of being civilized (Outram, 2004). To the 17th century English philosopher John Locke, an early archetype of an enlightened thinker, the discovery of the New World of America "enlarged the sphere of contemplation" about "civilized man" and his "savage ancestors" (Locke, 1690). There was more to discover. The scientific journeys of exploration around the Pacific in the 18th century by James Cook, another archetypal figure of the Enlightenment, were significant in creating the imagination and knowledge of the age. Although the Enlightenment was a European phenomenon, its scope became global as the scholars of Europe attempted to classify and order the peoples, plants and animals of other worlds as well as map their landscapes. Maori scholar Linda Tuhiwai Smith succinctly sums up the process: "They came, they saw, they named, they claimed" (Tuhiwai Smith, 2001, p. 80). 'Discovery' was the watchword of the Enlightenment (Porter, 2000), realised only by a few Europeans but imagined by many others and evident in the fashion for paintings of drawing room explorations with globes ahd...
