Emily Dickinson Essays - American Christians, Emily Dickinson

Emily Dickinson Essays - American Christians, Emily Dickinson Emily Dickinson Emily Dickinson is one of the most well known poets of her time. Though her life was outwardly uneventful, what went on inside her house behind closed doors is unbelievable. After her father died she met Reverend Charles Wadsworth. She soon came to regard him as one of her most trusted friends, and she created in his image the ?lover? whom she was never to know except in her imagination. It is also said that it was around 1812 when he was removed to San Fransico that she began her withdrawal from society. During this time she began to write many of her poems. She wrote mainly in private, guarding all of her poems from all but a few select friends. She did not write for fame, but instead as a way of expressing her feelings. In her lifetime only six of her poems were even printed; none of which had her consent. It was not until her death of Brights Disease in May of 1862, that many of her poems were even read (Chelsea House of Library Criticism 2837). Thus proving that the analysis on Emily Dickinson?s poetry is some of the most emotionally felt works of the nineteenth century. Miss Dickinson is often compared with other poets and writers, but ?like Shakespeare, Miss Dickinson is without opinions? (Tate 86). ?Her verses and technical license often seem mysterious and can confuse critics, but after all is said, it is realized that like most poets Miss Dickinson is no more mysterious than a banker. It is said that Miss Dickinson?s life was starved and unfulfilled and yet all pity is misdirected. She lived one of the richest and deepest lives ever on this continent. It was her own conscious choice to deliberately withdraw from society into her upstairs room (Tate 83). She kept to ?only a few select friends and the storm, wind, wild March sky, sunsets, dawns, birds, bees, and butterflies were sufficient companionship for Miss Dickinson? (Loomis 79). She dealt with a lot both physically and psychologically and in the end she still came out on the top. So as Allen Tate best said it ?in her own historical setting Miss Dickinson is nevertheless remarkable and speci al? (82). Thomas Higginson said that ?the main quality of her poems is that of extraordinary grasp and insight, uttered with an uneven vigor, which was all her own? (78). The works and phrases she uses shows that she was unconcerned with the fact that no one else could understand her poetry, but instead, she was satisfied by using mere words in order to fit her own ear (Higginson 78). Miss Dickinson?s poetry was strictly confidential and written without the purpose of publication and merely as a way of expressing her own mind (Bloom 2838). ?Art forms were totally unknown to her, and nature was always viewed not in a cosmic way but in its smallest and most intimate forms? (Whicher 87). Allen Tate describes her biggest influence to be nature itself, and though she could not deal with the problems of society, she had such an attitude toward life that she was able to see into this character of nature more deeply than any other (84). Miss Dickinson?s poetry style contains ?flashes of wholly original and profound insight into nature and life? (Chelsea House of Library Criticism 2841). ?At first impression her tiny lyrics appear to be no more than the jottings of a half-idiotic school-girl instead of grave musings of a full grown, fully educated woman? (Monro 81). Miss Dickinson often writes out of habit allowing her poems to not require a point of view, but instead, they require for some of the deepest understanding, which allows her style to emerge even when she has nothing to say (Tate 86-87). Some consider her works to be the most original of her time, written with an unusual amount of emotion and often referred to as poetry torn up by its roots with rain, dew and earth still clinging to them? (Higginson 78). To others she was considered to be ?intellectually blind, partially dead, and mostly dumb to the art of poetry? (Monro 81). It was best stated by Allen Tate when he wrote,

History of Electromagnetism

History of Electromagnetism Electromagnetism  is an area of  physics  which involves the study of the  electromagnetic force, a type of physical interaction that occurs between  electrically charged  particles. The electromagnetic force usually produces  electromagnetic fields, such as  electric fields,  magnetic fields  and  light. The electromagnetic force is one of the four  fundamental interactions  (commonly called forces) in  nature. The other three fundamental interactions are the  strong interaction, the  weak interaction  and  gravitation. Until 1820, the only magnetism known was that of iron magnets and of lodestones, natural magnets of iron-rich ore. It was believed that the inside of the Earth was magnetized in the same fashion, and scientists were greatly puzzled when they found that the direction of the compass needle at any place slowly shifted, decade by decade, suggesting a slow variation of the Earths magnetic field. Edmond Halleys Theories How can an iron magnet produce such changes? Edmond Halley  (of comet fame) ingeniously proposed that the Earth contained a number of spherical shells, one inside the other, each magnetized differently, each slowly rotating in relation to the others. Hans Christian Oersted: Electromagnetism Experiments Hans Christian Oersted was a professor of science at Copenhagen University. In 1820 he arranged in his home a science demonstration to friends and students. He planned to demonstrate the heating of a wire by an electric current, and also to carry out demonstrations of magnetism, for which he provided a compass needle mounted on a wooden stand. While performing his electric demonstration, Oersted noted to his surprise that every time the electric current was switched on, the compass needle moved. He kept quiet and finished the demonstrations, but in the months that followed worked hard trying to make sense out of the new phenomenon. However, Oersted could not explain why. The needle was neither attracted to the wire nor repelled from it. Instead, it tended to stand at right angles. In the end, he published his findings without any explanation. Andre Marie Ampere and Electromagnetism Andre Marie Ampere in France felt that if a current in a wire exerted a magnetic force on a compass needle, two such wires also should interact magnetically. In a series of ingenious experiments, Andre Marie Ampere showed that this interaction was simple and fundamental: parallel (straight) currents attract, anti-parallel currents repel. The force between two long straight parallel currents was inversely proportional to the distance between them and proportional to the intensity of the current flowing in each. There thus existed two kinds of forces associated with electricity- electric and magnetic. In 1864, James Clerk Maxwell demonstrated a subtle connection between the two types of force, unexpectedly involving the velocity of light. From this connection sprang the idea that light was an electric phenomenon, the discovery of radio waves, the theory of relativity and a great deal of present-day physics.
