Charles Babbage

Charles Babbage (1791-1871) To begin with, Charles Babbage, an original innovative thinker and a pioneer of computing from Great Britain, was born on the 26th of December of 1791 in Walworth, Surrey and he died at his home in London on October 18, 1871. He was an incredible mathematician and it is mentioned that he was indisposed as a child so he mainly been educated at home. Babbage made contributions that may assured his fame irrespective of the Difference and Analytical Engines. After his wife’s death he was never again married. not necessary to put) He went at Trinity College, Cambridge in October of 1810. He was very disappointed about the poor variety of the math programs available there so he and some other friends decided to form the Analytical Society. In 1812 he transferred to Peterhouse, Cambridge but he failed to graduate with honours. He received a degree later without even being examined in 1814. After graduation Babbage was hired by the Royal Institution in orde r to lecture on calculus. There, in 1816 he was elected as a member of the Royal Society and found the Astronomical Society.In the meantime (1817) he received MA from Cambridge. Since 1828 and some years after, until 1839 he was named the Lucasian Professor of Mathematics at Cambridge. Charles Babbage also has the nickname â€Å"Father of Computing† due to his detailed plans for mechanical Calculating Engines, both the table-making Difference Engines (1821) and the far more ambitious Analytical Engines (1837), which were flexible and powerful, punched-card controlled general purpose calculators, containing many features which later reappeared in the modern computer.Because of the high error rate in the calculation of mathematical tables, Charles Babbage wanted to find a solution with which the mechanical calculations could be done with less or without errors. He was influenced by three different factors such as a dislike of untidiness; his experience working on logarithmic ta bles; and existing work on calculating machines carried out by Wilhelm Schickard, Blaise Pascal, and Gottfried Leibniz. During 1820, Babbage started the development of his first Difference Engine. It was a mechanical device that could perform simple mathematical calculations.Although he began promising, was unable to complete it due to huge expenses needed. After that,  in the 1830s Babbage began developing his Analytical Engine, which was designed to cope with much complicated calculations, but it was never built. (put what you think in diff. words.. ) Unfortunately because of critical tolerances required by his machines exceeded the level of technology available at the time and, though Babbage’s work was formally recognized by respected scientific institutions, the British government suspended funding for his Difference Engine in 1832.In 1833 Ada Augusta Lovelace met Charles Babbage and was fascinated with both him and his Engines. Later she became a competent student of mathematics, which was unusual for a woman at that time. Under Babbage's careful supervision Ada added extensive notes which constitute the best contemporary description of the Engines, and the best account we have of Babbage's views on the general powers of the Engines. It is often suggested that Ada was the world's first programmer.There remain only fragments of Babbage's prototype Difference Engine, and though he devoted most of his time and large fortune towards construction of his Analytical Engine after 1856, he never succeeded in completing any of his several designs for it. George Scheutz, a Swedish printer, successfully constructed a machine based on the designs for Babbage's Difference Engine in 1854. This machine printed mathematical, astronomical and actuarial tables with extraordinary accuracy.Babbage's work was continued by his son, Henry Prevost Babbage, after his death in 1871, but the Analytical Engine was never successfully completed, and ran only a few â€Å"prog rams† with disappointing results. Summing up, Babbage extent his achievements by writing about the assurance of life as well as breaking mathematical codes. His calculus engine was stayed in history for many years and until today left their mark in our world. It is remarkable that was create a foundation, with the name of Charles Babbage, in order to honor him and to recognize his work and how is connected to the modern computers.

The Scarlett Letter Essays (1445 words) - English-language Films

The Scarlett Letter Essays (1445 words) - English-language Films The Scarlett Letter The Effective Use of Symbolism The novel, The Scarlet Letter, by Nathaniel Hawthorne is an intriguing account of a Puritan community that experiences a breakdown in beliefs. The story deals with a woman, Hester, who commits adultery with a Calvinistic minister resulting in the birth of a child (Martin 110). As compensation for her crime of passion and her refusal to name her lover, Hester is sentenced to wear an embroidered scarlet letter on her bosom. It is this letter, or secret sin, that becomes the emphasis of the novel and assumes many different roles (Martin 111). Hawthorne starts the novel by portraying the literary reality associated with the different aspects of the letter (Martin 110). From the start, Hawthorne seems to say, this is a scarlet letter; because of that, it is capable of further meaning. The letter will have to carry the burden of the tale (Martin 111). Hawthornes use of symbolism is fully developed in the multi-meanings hidden in the scarlet letter through a variety of characters. The scarlet letter represents different ideals to different people and should be given the proper consideration (Martin 114). In the Puritan community, the letter is viewed as a moral obligation to inform others of Hesters sin, one that they feel should be dragged out into the sunshine (Hawthorne 43). They believe the letter symbolizes psychological and religious truth. The Puritans are a people amongst whom religion and law were almost identical, and in whose character both were so thoroughly Foti 2 interfused, that her mildest and severest acts of public discipline were alike made venerable and awful (Hawthorne 40). It is said that meager, indeed, and cold, was the sympathy that a transgressor might look for, from such bystanders at the scaffold (Hawthorne 40). The Puritans are firmly against Hesters actions and feels that she has disgraced them along with herself. They feel that she must take responsibility for her actions. The effect of her punishment however is not what the Puritans had hoped to achieve. Hesters sin has grown from that of passion to one of purpose. Even with Hesters sympathetic attitude, she was not filled with regret and therefore the letter had not done its task (Martin 122). To the Reverend Arthur Dimmesdale, the scarlet letter contains a whole new meaning. He views the letter as a constant reminder of his sin and cowardice. His guilt continues to grow as a result of his not being able to come forth in front of the community and take responsibility for his actions. His guilt and sin become magnified by his inability to stand beside Hester at the scaffold. Dimmesdale, also is ironically charged with questioning Hester and trying to convince her of the importance of identifying her fellow sinner (Hawthorne 52). He begins to feel more and more grief and it begins to affect his mental and physical state. He soon becomes weak; however, it is believed by the community to be because of his too unreserved self-sacrifice to the labors and duties of the pastoral relation (Hawthorne 80). When Dimmesdale is believed to be near death, the community again believes it is because the world was not worthy to be any longer trodden by his feet (Hawthorne 88). Dimmesdale se ems to be haunted by Satans emissary, in the guise of old Roger Chillingworth. This diabolical Foti 3 agent had the Divine permission, for a season, to burrow into the clergymans intimacy and plot against his soul (Hawthorne 94). Chillingworth proposes to Dimmesdale that a sickness, a sore place, if we may so call it, in your spirit, hath immediately its appropriate manifestation in your bodily frame (Hawthorne 99). However, Dimmesdale denies and refuses to discuss it with him. Dimmesdale becomes weaker and weaker because by the constitution of his nature, he loved the truth, and loathed the lie, as few men ever did. Therefore, above all things else, he loathed his miserable self! (Hawthorne 105). Before Dimmesdales death, he finally confesses to his sin on the scaffold and frees his soul and conscience. Spectators have testified to seeing on the breast of the unhappy minister, a SCARLET LETTERthe very semblance of that worn by Hester Prynneimprinted in the flesh (Hawthorne 182).

Liberal Art Studies Essay Example | Topics and Well Written Essays - 1500 words

Liberal Art Studies - Essay Example Perhaps in more authoritarian societies using cunning and deceit are necessary to rise out of poverty, but one would hope that in a free society that although using the end to justify immoral means may give a person wealth, it will damage their souls and lead to negative consequences in the end. In this sense, the liberal arts are important because they serve as a guide for moral and ethical behavior and show that one’s duty to the state and their fellow man is rewarding in many ways, even economically. This essay will focus on the importance of the liberal arts in modern as well as ancient times through the writings of Kimball, Shorris, Sullivan, Cicero, and Machiavelli. Additionally, the essay will focus on the problems that arise when what is viewed as modern realism is pitted against traditional moral idealism. The liberal arts can certainly have a positive effect on professional life. The liberal arts teach of things like ethics and integrity. Shorris believes that humani ties does function on its own, but does not have its full effect unless it is integrated into professional life (2000). The ancient Greeks also believed it was essential to the welfare of the state that humanities and public life function together. Morals are generally inherent in any professional career. Being a professional carries with it a responsibility to clients, communities, and society in general. This social contract is the basis of professionalism. Therefore it is important that professionals exercise moral judgment in their professional careers. Because a professional is confronted with moral dilemmas, a liberal education is something that is very useful to society in general. A liberal education teaches us about morals and can be seen as something that makes a person’s professional career more rewarding when it is fully guided by ethical principles. Many people feel that a job is just a job and is a means to an end, but the study of liberal arts tell us that a pe rson and their job can’t be completely separated. In other words, a person influences the job and the job influences the person. Because of this, it is important to realize that a job, or making money, can often impose moral decisions upon the professional. Also, a person who is very immoral and unethical can use their job as a means to lie, cheat, and steal from others. Sullivan believes that, at its best, a profession can provide an important benefit to the individual as well as to society as a whole. However, at its worst, a profession can strip a person of their ethics and their humanity (2004). Using this definition he illustrates that professionalism is headed down a dangerous road as more and more people feel that economic ambition is the only thing that matters and things like loyalty and social responsibility are being thrown by the wayside. Sullivan also believes that society is in danger of simply training people instead of educating them and explains that this cou ld lead to people only using one small part of their brain. Often certain professionals are only focused on the technical aspect of their career and do not regard anything else as important. This type of person may be doing their job but they are not engaged in examining their lives and therefore it is difficult for them to achieve a truly fulfilled working life. The study of liberal arts is something that is capable of making a person’s everyday life better because it can take a person out of their

Plagiarism Assignment Example | Topics and Well Written Essays - 250 words

Plagiarism - Assignment Example The relevancy of the information presented tends to prove or disprove facts. In some cases, the officer conducting the data analysis may decide to produce work acquired by another colleague for a different investigation that is similar. This is illegal and the person in question will lose their job and face possible prosecution (Gaines & Miller, 2014). In a prosecution case, the prosecutor attempts to establish guilt beyond reasonable doubt. In cases where the prosecutor is lazy, and attempts to present plagiarized information in front of a jury, the jury might not be convinced. This is because the prosecutor will not have facts or will contradict him/herself or maybe the judge/ jury may recognize the facts as those presented in a different case. The guilty person may end up walking free because of the prosecutor’s laziness (Gaines & Miller, 2014). When it comes to preparing witnesses for cross-examination, the defense attorney and the attorney ought to sure that the witnesses produce work based on their own knowledge and not something they heard (hearsay). The prosecutor and the attorney should also avoid coaching the witnesses as this may lead to perjury, which is an offense (Gaines & Miller, 2014). The perjury comes in when the witness lies after taking an oath. The lies might be factual though not based on the witnesses’ knowledge especially by giving information experienced or witnessed by another individual. If the court finds out that the lawyer and prosecutor were part of this, they may lose their license (Gaines & Miller,

Evolution Essay Example | Topics and Well Written Essays - 750 words - 1

Evolution - Essay Example Although Scientists are convinced that macroevolution occurs resulting in emergence of new species, this is a misconception. This paper argues that macroevolution has never and will never occur. The reasons given by scientists to support occurrence of evolution are controversial and disputable. Irrespective of there being no observable evidence to show occurrence of macroevolution, scientist continue to defend the notion that the existing species evolved from primitive species through gradual stages. There is not recorded evidence that any distinct organism ever evolved into a different kind of organism. This shows that evolution of any significant scale has never occurred and will never occur (Camp, 2006). If the process of evolution ever occurred, then someone must have observed it. On the contrary no one has ever witnessed an organism undergo evolution. Additionally, there are no transitional forms of organism in existence. If evolution does occur, then different organisms of different species would at least be seen in their transitional stages (Denton, 2010). On the contrary, organisms belonging to same species are almost indistinguishable in terms of the traits they possess. Although a single species may have different varieties, there are no organisms in the transition stages that show characteristics such as shared features between two different species. For example, if human evolved from the apes, there should be some existing ape like human in the process of evolving into humans. On the contrary, contemporary apes are different from humans with no entities in the transitional stages (Camp, 2006). Another reason why macroevolution is an invention by scientists is failure of experiments in the lab. Scientists have carried out experiments using rapidly reproducing organisms such as fruit flies in an attempt to produce better species. Such experiments have failed even with use of
