The Innovation and Use of the Electrical Wire - 916 Words

Electrical Wire When metal is formed into a single, flexible strand, or fiber, it is called wire. Metal wire has been used by humans in jewelry and other decorative items since the beginning of the use of metal in the second millennium B.C. This type of use primarily involved precious metals like gold and silver; but also more common metals like copper. But with the discovery of electromagnetism, metal wire was found to be a good conductor of electricity, especially that made of copper. As with most electrical devices, the current form of electrical wire was invented by the Father of Electricity, Thomas Edison. He was awarded a patent in 1892 for what he described as an electric conductor, but was really an insulated wire that was both water and fire proof. Edisons invention consisted of a conducting wire, a covering made of cotton braid, and an outer covering made of non-conducting rubber. (Dini 2006) This new invention could conduct electricity without the danger of starting fires or being shorte d out by water. Wire is produced by forming a part of the metal into a small piece so it will fit through a die that has a hole through which the metal will be drawn. It is then slowly drawn it through a series of smaller and small dies until the diameter of the wire reaches the desired size. It can then be used in everything from wire netting and wire rope to electrical wire; which conducts the nations power.

Racism And Discriminatory Events Throughout History

Mohannad Alkhatib TKM Paper Millions of humans have suffered at the hands of racism and discriminatory events throughout history. The majority of these racial and discriminatory events are the basis of Harper Lee’s To Kill a Mockingbird. The novel references Jim Crow laws, mob mentality, as well as the issues of racism and discrimination in that period of time. To begin, the first topics inspired by real life events in the novel were the Jim Crow laws. Jim Crow was a set of laws that aimed to discriminate against African Americans in every aspect of life. First, white people believed that the laws were necessary because they thought white people were superior to blacks. They felt black people must be placed below whites to satisfy these†¦show more content†¦Furthermore, the picture shown represents how the Jim Crow laws interpreted black people because it shows a dirty man with torn clothes looking exaggerated and thoughtless. This concisely shows that the Jim Crow laws treated black p eople as if they were animals emotionally and physically (V.). Next, the citizens of Maycomb obeyed and enforced the Jim Crow laws. When Tom Robinson stated he felt sorry for Mayella, the white folk in the courthouse reacted with distaste. They were appalled by Tom’s comment, as they believed it implied he felt superior to Mayella (Lee 264). Likewise, Mayella was forced to say Mr. Robinson raped her because it was looked upon with disdain to develop feelings for a black person. This was believed as white people thought blacks were below whites (Lee 272). In addition to this, during Mr. Gilmer’s cross-examination of Tom, he spoke to Tom in a condescending tone. The manner in which he spoke to Tom implied that Mr. Gilmer thought Tom to be no more than an animal (Lee 263). As shown, the book contains a plethora of examples of Jim Crow laws, but it also contains multiple examples of mob mentality. Second, mob-mentality is a vital topic in Harper Lee’s To Kill a Mock ingbird. Mob mentality is the way people react and behave when they are in a large group. Some instances of mob mentality in our present day society are large crowds at sporting events, a large quantity of shoppers rushing to make a

Analysis Of Miles Davis Kind Of Blue free essay sample

In early 1959, jazz trumpeter Miles Davis laid down the foundation for a whole new style of Jazz music. Through his Kind of Blue+ modal Jazz was born. This record became a classic, at times showing Its complexity through the soloing, but also allowing the educated listener to revel in the simplicity of the modes. Davis planted the seeds for this new style in his album Milestones+ but Kind of BlueO showed that the style had matured and was more developed. From the introductory piano/ bass duet to the final notes, it is clear that Davis captured something original.The album was recorded In only two sessions and went on without any prior rehearsal or music written out. Davis only provided general of each song for the musicians, which they read and improvised over. For the task of recording, Davis put together an all-star lineup with some of the greatest Jazz musicians in music history. We will write a custom essay sample on Analysis Of Miles Davis Kind Of Blue or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The rhythm section was composed of Paul Chambers on bass, Jimmy Cob on drums, and Bill Evans on piano, except for Freddie Freeloader+, which featured Wanton Kelly on piano. To round out the band was the horn section, led byDavis himself, and completed by alto saxophonist Cannonball Dearly, and tenor John Coloration. The individual band members were great musicians in their own respect, but when shepherded by Davis for the Kind of sessions, the music they produced was incredible. If Kind of Blue+ is a musical Journey, then surely the rhythm section Is the flight crew, Insuring that the passengers have a smooth ride. Throughout the entire album, the beat Is kept steady, the coming never clutters or Inhibits the soloist, and the chord changes are right on the money. With a tight rhythm section laying a solid inundation, Davis, Dearly, and Coloration are free to take their solos in any direction they choose. Even from the first song, a mellow blues based tune, So What+, we can hear the creatively at work. The Interplay between Evans and Chambers In the Intro Is so melodious: It Is hard to believe It was achieved without rehearsal. Then the signature melody line, delivered by Chambers, then answered by the horn section, kicks in before we are led into the first solo section. Davis then takes us into his modal playground and allows us to listen as he runs free.The solo makes you run the motional gamut from sheer Joy to melancholy and despair in the space of a minute. The band performs equally well on the second track, Freddie Freeloader O and provide a melody line that many musicians use for impromptu jam sessions because of its chattiness and simplicity. It is a pleasant set up for the next tune called Blue in Green+. Blue in Green+ is interesting because It is not in a standard form, but in a ten-bar circular form. This provides a challenge for the soloist to follow the form, but they manage the changes beautifully and effortlessly. D has an overcast mood assisted by Davis use of a Harmon mute and the pieces minor tonality. To end the record, they recorded Flamenco Sketches+, the only song in these sessions to have two takes. All in all, Kind of Blue+ has worked its way into the hearts of millions of Jazz fans with good reason. Davis has never had a tighter band behind him and every player exudes their confidence and knowledge of their instrument with every note they play. The end product is a beautiful blend of evocative solos and innovative progressions that deserve to be heard, studied and loved by anyone who appreciates good Jazz.

Oil In April 2000 Essays - Petroleum Politics, Commodity Markets

Oil In April 2000 W A S H I N G T O N, April 6 ? The good news for consumers is gas prices are anticipated to drop this summer. But the bad news is the decline will be slow. With an increase in international oil production as a backdrop, the Energy Department today dramatically revised its forecast for summer gasoline prices. The agency said prices should peak later this month and begin dropping sometime in May, averaging about $1.46 a gallon throughout the summer. Even Cheaper Fall Prices And there's even more good news: Gasoline prices may dip lower still by fall, according to the agency. Prices may fall to a national average of $1.39 after Labor Day, the department's Energy Information Administration said in its revised short-term forecast. ?By then I expect we will have started to see some economic growth deterioration and I think from there we probably will see demand start to come under some pressure,? said Peter Beutel, president of Cameron Hanover, an energy risk management firm in Connecticut. ?So, I think we probably will see prices closer to $1.30 or maybe even $1.25.? What Happened to the $2 Estimate? Just a month ago, the Energy Department said even with increased oil production, gasoline prices were expected to soar to a national average of as much as $1.80 a gallon and likely reach $2 a gallon in some places by July. So what's changed between now and then? A key international oil meeting in Vienna, Austria. The EIA in its latest forecast assumed additional oil would begin hitting the U.S. market by June as a result of a decision March 28 by the Organization of Petroleum Exporting Countries. OPEC agreed to boost production by as much as 1.7 million barrels a day. Other non-OPEC producers also have said they would increase production. And production increases mean refilled petroleum stocks and lower prices for oil products including gasoline. ?We are more optimistic today. Some of the tightening of the market has improved,? said EIA Administrator Jay Hakes. Nationally, the average cost of regular grade gasoline was $1.52 a gallon in March, with the average for all grades, including premium, a nickel higher, the agency said. Revisions Still 25 Percent Higher But don't get too excited just yet. The agency's latest revision is still 25 percent higher than summer prices a year ago. The average motorist is expected to pay about $170 more for gasoline this summer than last, according to the EIA. Additionally, according to the new forecast, gasoline stocks are likely to remain at the lower end of the normal range through the summer. Worries about stocks aside, the latest gas price revision is good news for the Clinton administration that has been fretting over the prospects of gasoline prices soaring to $2 a gallon this summer and additional potential shortages. But Energy Secretary Bill Richardson has said repeatedly that with the additional oil production from OPEC and other producers, prices should gradually recede. Strong Summer Demand for Gas The department's latest price forecast also assumes no refining problems with refineries running at nearly 97 percent capacity through the summer. If there are refinery shutdowns, prices would spike higher, the agency said. And although summer gasoline prices will be 25 percent higher than last year, demand is expected to remain strong, exceeding summer demand a year ago. The agency predicts refiners should have no trouble meeting the increase, barring any major refinery shutdowns. The report also predicted that crude oil prices will continue to drop for the remainder of the year, assuming continued increases in world production. Social Issues

Paper Islam

Paper Islam Paper Islam Caroline McDaniel World Civilization Ms. Reif March 1 2015 Women in Islam The dress code of women in Islam is a very important part of life. A hijab is a veil that covers the head and chest, which is particularly worn by some Muslim women beyond the age of puberty in the presence of adult males outside of their immediate family. Muslim women choose to wear the hijab or other coverings for a variety of reasons. Some women wear the hijab because they believe that God has instructed them to wear it as a means of fulfilling His commandment for modesty (arabsinamerica). Muhammad and the beginning of Islam changed the status of women by issuing new laws based on what was recorded in the Qur’an, which is the holy book for Muslims. The Qur’an gained many more rights for women. A women could refuse a marriage proposal, but cultural and social pressures often forced her to comply with her parents’ wishes. A women could own property, but the only property that she truly owned were the gifts she received from her husband at marriage and her dowry, which was her family money. (Esherick 33). Some quotes from the Qur’an are â€Å"Muhammad taught that women had rights similar to men, but that men were ultimately stronger and had more authority. Muhammad taught that men could admonish their wives, refuse to share a bed with them, and beat them lightly so as not to injure them.† (Qur’an 2:228). (Esherick 48) Muslim societies have required women to cover themselves more modestly than men, covering not only their heads but also most of their bodies and even their faces. Examples of clothing that Islamic women would wear are a burqa, a mask that covers a women’s face. Young girls are not required to cover themselves with a burka. They are required to wear it when they are in public or in a presence of men who are not family members. (Pendergast 77). A chador which is a full – covering shroud worn mostly by rural women. A caftan which is full- length, loose- fitting robe with long slee ves. An Abaya, an outer garment made of tightly fitting cotton gauze, usually back, that covers the entire body and head. It is worn over other clothing. The Jilbab that is a cloak or loose outer garment that covers everything but the eyes. (Esherick 60). Some exceptions to the clothing rules are that Arab women are allowed to wear form- fitting clothing when they are with only their husbands, in their homes, around certain immediate family members, with only believing women, women who follow the same rules, and caring infants or small children

The Family of Woody Guthrie A Long Way to Oklahoma

The Family of Woody Guthrie A Long Way to Oklahoma When it comes to biographies of famous people, there is hardly a single detail of a celebrity’s that goes unnoticed by the crowd, yet there is an obvious and nonetheless strange gap of knowledge concerning the rest of the family members or the celebrity’s closest relatives.Advertising We will write a custom essay sample on The Family of Woody Guthrie: A Long Way to Oklahoma specifically for you for only $16.05 $11/page Learn More It is as if all famous people were manufactured right before they gained world recognition and had no relative attached. The same can be said about Woodrow Wilson Guthrie, known as Woody Guthrie, an American folk singer-songwriter. However, despite his family was not as famous as him, Charles and Nora Guthrie deserve just as much respect. One of the most fascinating things about Woody Guthrie’s family was that each of its members had a very unique personality and the features of character, which, quite honestly, would, probably, be completely incompatible in any other person. As the existing records say, Woody’s father, who was known among the neighbors and his fellow citizens as a politician, taught his son the charm and secrets of the Indian and Scottish music. Other sources, however, point at other influences that Charles Guthrie had on his son, some of them leaving much to be desired. For example, it is a notorious fact that Charles Guthrie was a racist and that his son supported his political viewpoint (Kinchen). However, there are other peculiar facts that even this sad bit of information out. For instance, the notorious fire, which gave Charles Guthrie severe burns, left a truly shocking impression on his son; as Woody Guthrie would say later on, this event would make him appreciate more not only the people whom he was close to, but also what these people shared with them. Thus, Woody’s fascination with music began owing not as much to his father’s stories, as t o the chain of events that led woody to appreciating these stories.Advertising Looking for essay on biography? Let's see if we can help you! Get your first paper with 15% OFF Learn More Despite the obvious strong influence of Charles Guthrie, Woody’s mother, Nora also changed her son’s life considerably with her passion for art and the willingness to share this passion with him. Unfortunately, Woody found out very soon – in fact, too soon, for a young child, – that his mother was suffering from a terminal disease, known as Huntington’s syndrome. Allowing Woody to understand how fleeting the moments of sharing love with his parents are, the boy’s first acquaintance with the fact of inevitable death, which sooner or later attacks anyone, including his closest relatives, his relationship with his mother can also be considered as an important factor in defining Woody’s further life and the ideas that he would commu nicate through his songs. These relationships between Woody and his mother, however, turned even complicated as the boy realized that the disease, which his mother was suffering from, affected their relationships greatly, seeing how it changed his mother irreversibly. Though it was not proven completely, it was believed that the fire mentioned above was set by Woody’s mother during one of her fits (Reineke 7). The impressions that shaped Woody Guthrie’s vision and talent of a musician were not restricted to the influence of his parents, though. Apart from his loving, though definitely not quite happy, parents, Woody also built very close relationships with his uncle, which would later on be reprinted not only in his songs, but also the way in which the musician would write his songs. Jeff Guthrie not only taught young Woody how to play the guitar, but also supported him in his darkles days, helping him get over the tragic death of his parents and the fact that his fami ly was literally falling apart. As for Jeff being the influence for Woody as a future musician, it will be reasonable to admit that at this point, the future folk star needed not spiritual guidance in his search for the music that he wanted to play – it was pretty much clear by then that Woody was into folk – but learning how to play the instrument. This was when Jeff’s old guitar came in handy; thrown aside when Jeff no longer had time for getting in contact with his artistic side, it was finally put to practice. Guthrie started learning to play the instrument and started performing, slowly starting to understand that his hobby was more than a fad.Advertising We will write a custom essay sample on The Family of Woody Guthrie: A Long Way to Oklahoma specifically for you for only $16.05 $11/page Learn More When watching Woody cross the threshold of his house, Jeff could hardly think of who his nephew was going to become pretty soon, as w ell as what part he would play in this transformation (Sanders). The parents of a musician who made folk and country music a complete craze in the USA, Charles and Nora Guthrie might not have been as well-known as their son, but they surely led very decent and nonetheless interesting lives. In addition, it is obvious that Woody’s siblings have also contributed to his vision and shaping of his personality, which would later on be reflected in his songs. Inspired by his outstanding, though inordinately modest, family, Woody had all rights to be proud of not only the long way that he went through, but also of the people who helped him to start his journey.

Poetry Analyze - Essay Example The poem has a whole bunch of ideas concerning parenthood and the roles of both the parents in bringing up a home. It tells a story of a complete family comprising a father, a mother and children. The mother is a homemaker and takes care of her family by doing home chores such as cleaning the diapers and ensuring her children are safe. The dad on the other hand works to provide for the family, it be evidenced by the fact that it is in the evening that we are introduced to her husband who probably is from work. She tends to the needs of her husband as said in the second last stanza of the poem, â€Å"later that night when Thomas rolled over and lurched into her.† From the last two stanzas, the poem introduces the relationship of a couple in parenthood. These two people are in very different situations. One goes to work to provide for the family, the other takes care of the family by looking after the kids. In all these occurrences, we see the way roles are divided in the running of family affairs. The situation of the woman is that which makes her selflessly dedicate herself to her roles as a mother. Despite the fact that she needs time for herself, she has no freedom at all to be herself in the family; she puts her family first in line and only gets the pleasure of resting for an hour. The rest of the time, she is a mother and a wife. This shows her dedication to parenthood. From the last two stanzas, we see the way the woman is submissive to Thomas by taking care of his needs as a husband. Thomas does not notice how tired the wife has been from the day’s activities. She does not complain about it to her husband instead she does what she wants her to do. This portrays Thomas as a man who is not caring about his wife because we are shown from the last stanza that â€Å"Thomas rolled and lurched into into her, she would open her eyes and think of the place that was hers for an hour.† This means that as a wife she is withdrawn
