The Phonograph's early beginnings In 1876 Edison had opened the first industrial research laboratory, at Menlo Park, New Jersey.

Other News about the Record Player EMILE BERLINER demonstrated the first flat-disc gramophone to an audience in Philadelphia on May 16 1888. His model quickly caught on, overtaking Mr Thomas Edison's machine, invented a decade before, which ran on cylindrical records.

- 22682: Symbolism In The Scarlet Lette
- ... religion. The town maintains a sense of strict moral values and disciplinary measures in accordance with the Puritan religion. Therefore, the town stands for lawfulness and purity. It serves as a contrast to Hester Prynne s scarlet letter. The prison that the city was built around serves as a symbol as well. It represents guilt and the human tendency to sin, and it also symbolizes penance. Hester is forced to spend time in jail for committing the sin of adultery, and it is the starting point of Hester s trek of shame to the scaffold in the market place. The scaffold itself is another symbol Hawthorne uses. Like the prison, it also symbolizes sin and guilt. The very ideal of ignominy was embodied and ... Hester is forced to stand for three hours as punishment, where Dimmesdale, Pearl, and Hester stand in the night, and where Dimmesdale reveals himself and dies. It is also a symbol of truth because Dimmesdale s great revelation occurred there. The second setting is the forest just outside of the town. It proves to be a kind of dramatic foil to the idealistic Puritan society. The Puritans maintain a community ...

In 1589 he became a professor of mathematics at Pisa, where he is reported to have shown his students the error of Aristotle's belief that speed of fall is proportional to weight, by dropping two objects of different weight simultaneously from the Leaning Tower At Padua, Galileo invented a calculating “compass” for the practical solution of mathematical problems ... the strength of materials. He showed little interest in astronomy, although beginning in 1595 he preferred the Copernican theory (sun centered theory)—that the earth revolves around the sun. Only the Copernican model supported Galileo's tide theory, which was based on motions of the earth. In 1609 he heard that the Dutch had invented a spyglass, what is now called a telescope. In August of that year he presented a ... and had time for research and writing. By December 1610 he had observed the phases of Venus, which contradicted Ptolemaic astronomy and confirmed his preference for the Copernican system. The professors of philosophy scorned Galileo's discoveries because Aristotle had held that only perfectly spherical bodies could exist in the heavens and that nothing new could ever appear there. Galileo also disputed with professors at Florence and Pisa over hydrostatics, ...
- 22684: Animal Farm: Struggle for Power
- ... Farm, but the animals rename it to Animal Farm, and when the pigs take over, they change the name back to Manor Farm. The time setting for this story is some point during the 1940’s.

There are also the other dogs on the farm, who had side things going on with Napoleon, and eventually took away Jesse’s litter from her, so that they may become “guards” to Napoleon and his “empire”. What each thought and did developed the characters. For example, the horse Boxer’s character was developed by the fact that he was such a diligent worker, and trusted everything that the pigs said.

- ... fighters discovered the power on the Minuteman, the average American gun owner.

The founding fathers of the country understood that an armed populace was instrumental in fighting off oppression, and they made the right to keep and ... resist their efforts. An unarmed man stands little chance against and armed one, and these armed men saw their plans work completely. It was a full century before the civil rights activists of the 1960’s were able to restore the constitutional freedoms that blacks in this country were granted in the 1860’s(46). Today’s gun control activists are a slightly different breed. They claim that gun violence in this country has gotten to a point where something must be done to stop it. They would ...

- 22689: Camus' "The Stranger": Choice and Individual Freedom Are Integral Components of Human Nature
- Camus' "The Stranger": Choice and Individual Freedom Are Integral Components of Human Nature Camus's The Stranger is a grim profession that choice and individual freedom are integral components of human nature, and the commitment and responsibility that accompany these elements are ultimately the deciding factors of the morality of one's existence. Meursault is placed in an indifferent world, a world that embraces absurdity and persecutes reason; such is the nature of existentialist belief, that rationalization and logic are ultimately the essence of humanity, and that societal premonitions and an irrelevant status quo serve only to perpetuate a false sense of truth. Meursault's virtue, as well as his undoing, lies in his unique tendency to choose, and thereby exist, without computing objective standards or universal sentiment. His stoic, de facto existentialism is a catalyst for endless conflict ...

Later when the system is booted from the system hard disk, the Junkie virus becomes memory resident at the top of system memory below the 640K DOS boundary, moving interrupt 12's returns. Once memory resident, Junkie begins infecting .COM files as they are executed, and corrupts .COM files. The Junkie virus infects diskette boot sectors as they are accessed. The virus will write a copy of ... diskette, and then alter the boot sector to point to this code. On high density 5.25 inch diskettes, the viral code will be located on Cylinder 79, Side 1, Sectors 8 and 9." Junkie's description is that of a basic stealth/Trojan virus which have been in existance for 10 years. They also listed Anti-exe as one of the top ten viruses but did not acknowlege the fact that it has three aliases. It's no wonder that the general public is confused about computer viruses!
