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
