Essay Lottery Idea

Idea of Lottery Some people like to make a quick buck without toiling much. But the majority work hard to earn a living. Both of them cannot understand the other point of view. Those who don’t like to work cannot understand how the other group can toil all day long just to earn some money when there are other methods like lottery and gambling to make money quickly. Oh the other hand, those who believe in hard work cannot understand how people can hope to survive without working hard. It is true that people have to work hard to live a proper life and become successful. So many people have shown by example that it can be done. There are thousands of millionaires and less number of billionaires throughout the world history, who were able to amass wealth through their hard work and ingenuity. They have demonstrated to the world that man can succeed against all odds and become hugely successful. People who believe in the lottery and gambling, on the other hand, depend on luck and destiny to become rich. They lack any kind of self-confidence and wait for providence to smile at them. They are not sure when or if that would ever happen. But they are always eagerly waiting for it to happen. They would rather wait patiently than do anything constructive that can make them successful. Therefore, lottery and other kinds of get-rich-quick schemes simply destroy people’s will to work and succeed in life. People are lulled into a state of expectancy where they do nothing but wait for something to happen. To my mind, this method is extremely unreliable and it is always better to control your life on your own, than simply to wait for some fictional chance to become rich.

“AP” By John Updike Presents Readers With A Straightforward

â€Å"AP† by John Updike presents readers with a straightforward narrative structure that features striking characterization. The first paragraphs contain eloquent descriptions of Queenie and her friends’ physical characteristics and the alluring draw of their blatant sexuality on display. However, a deeper and more specific kind of characterization comes to the forefront as the story develops. The text contains perceptive character profiles of the various types of newly emerging American consumers. â€Å"AP† was published in 1961. This was a time of rapidly expanding American consumerism and an unquenchable thirst for countless products and services. Lengel, the manager, is a businessman who, within limits, benefits from the capitalist system he†¦show more content†¦Sex appeal holds the boys’ attention as the girls walk around the store; however, it is this sexuality framed against the context of capitalism that stirs Sammy to quit his job. There are multiple moments in the text that offer visual images of this melding of capitalism and sex. Sammy describes the oddity of seeing a bathing suit, not on the beach, but parading around the AP â€Å"under the fluorescent lights, against all those stacked packages† (Updike 296). Or again when Queenie retrieves a folded dollar bill from the â€Å"hollow at the center of her nubbled pink top† (Updike 297). These descriptive passages embody the merging of sexuality and consumerism that drives the story. They also serve as perfect visual representations of the inherent nature of capitalism’s influence on consumers: i.e., always in the background but never the less forcibly present, or inescapable. Tyson makes a point about how dangerous it is for capitalism to exist as a â€Å"distant backdrop† in society (Tyson 133). In this way, capitalism influences people without their conscious knowledge, therefore leaving them ill equipped to tangibly understand a nd resist its influence. This is the exact dilemma in which Sammy finds himself at the end of the story. The capitalist system that thrives in Updike’s â€Å"AP† is also portrayed more traditionally and straightforward at various other points in the story.

1.Oxidation is when a substance gains oxygen, lose Essay Example For Students

1.Oxidation is when a substance gains oxygen, lose Essay s electrons, and itsoxidation state increases after a reaction. One example of an oxidation reaction is:C + O2CO2(s)(g)(g)In this reaction, the carbon has become oxidised (gained oxygen) and itsoxidation state has changed from 0 to +4. Explosive reactions are oxidation reactions that happen very quickly andexothermically, and where more gases are released to cause greaterpressure, and thus an explosion. An example of this is the ignition of black powder:KNO3 + 3C + SK2S + N2 + 3CO2 (s)(s)(s)(s)(g)(g)Source 1In this reaction, The C and S are fuels and the KNO3 is an oxidiser. Theproducts are mainly gases, which cause an increase in pressure. Thereaction happens quickly because there is oxygen contained in the reactantKNO3, this means the oxygen is available immediately, which allows the Cand S to burn extremely quickly. The extent of explosive reactions depend on the speed of the reaction,energy released, and amount of pressure created due to the production ofgases. 2. The earliest explosive is believed to have been invented in Chinacenturies ago. This was named black powder which is composed of compressedpotassium nitrate, Sulphur and Charcoal. This was used for centuries forfireworks and warfare. One problem with it being used in warfare was that the explosion produced alot of smoke, which obscured sight. In battles where there was extensiveuse of black powder (or gun powder when used in guns as a propellant) thegrounds were covered in smoky fog. Nitrocellulose (or Gun cotton) was accidentally discovered by Dr ChristianSchnbein in 1846 when he was experimenting with acids at home. Hisdiscovery led to the research of Nitrocellulose in the 1860s for use inwarfare. A year later, Ascanio Sobrero was also experimenting with concentratedacids, mixing nitric and sulphuric acid together, along with glycerine (amore chemically accurate name is glycerol as it was later discovered to bean alcohol). He found that this yellow oil was a very unpredictable explosive that couldbe detonated by the touch of a feather. This new explosive was namedNitroglycerine. Later, a scientist called Alfred Nobel continued Sobreros research, makingNitroglycerine safe by mixing it with Kieselguhr (a silica-based mineral,similar to clay). The resulting paste was shaped into rods to form sticksof dynamite which would only detonate when intended. Nobel had invented thefirst safe high explosive. This explosive was difficult to detonate withfire or a fuse, and so Nobel used a smaller explosion to detonate theDynamite. He used small amounts of black powder to do this. This was later made more effective by replacing the Kieselguhr withsubstances that had similar properties but would themselves burn orexplode. This was called Dynamite no.2. He later thought of usingcollodion, partially nitrated cellulose, instead of fully nitratedcellulose. The result was a stiff jelly-like mass called blasting jelly,which was more effective than dynamite, for both the nitroglycerine and thecollodion were explosive. By the 20th century, black powder used in guns was replaced by smokelesspowder made from Nitrocellulose. Unlike black powder, this explosive couldbe detonated by percussion, therefore a fuse was unnecessary. The British army developed smokeless powder called cordite in the 1880s,made from Cellulose trinitrate and glycerol trinitrate. The end product is not in fact an explosive, but merely a very rapidignition that creates pressure from the produced gases. Source 2During the second world war, TNT (trinitrotoluene) was developed, which hasNO2 nitro groups and not -O-NO2. Because it does not react with metals andhas a melting point of 81oc, it could be poured into metal artillery shellsand bombs. .uab0a0cc6304beb0b8ea77b248bb88a75 , .uab0a0cc6304beb0b8ea77b248bb88a75 .postImageUrl , .uab0a0cc6304beb0b8ea77b248bb88a75 .centered-text-area { min-height: 80px; position: relative; } .uab0a0cc6304beb0b8ea77b248bb88a75 , .uab0a0cc6304beb0b8ea77b248bb88a75:hover , .uab0a0cc6304beb0b8ea77b248bb88a75:visited , .uab0a0cc6304beb0b8ea77b248bb88a75:active { border:0!important; } .uab0a0cc6304beb0b8ea77b248bb88a75 .clearfix:after { content: ""; display: table; clear: both; } .uab0a0cc6304beb0b8ea77b248bb88a75 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uab0a0cc6304beb0b8ea77b248bb88a75:active , .uab0a0cc6304beb0b8ea77b248bb88a75:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uab0a0cc6304beb0b8ea77b248bb88a75 .centered-text-area { width: 100%; position: relative ; } .uab0a0cc6304beb0b8ea77b248bb88a75 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uab0a0cc6304beb0b8ea77b248bb88a75 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uab0a0cc6304beb0b8ea77b248bb88a75 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uab0a0cc6304beb0b8ea77b248bb88a75:hover .ctaButton { background-color: #34495E!important; } .uab0a0cc6304beb0b8ea77b248bb88a75 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uab0a0cc6304beb0b8ea77b248bb88a75 .uab0a0cc6304beb0b8ea77b248bb88a75-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uab0a0cc6304beb0b8ea77b248bb88a75:after { content: ""; display: block; clear: both; } READ: ALS DISEASE Oral Notes Essay3. For a reaction to be explosive, it must happen extremely quickly, itmust be exothermic (heat discharged), and gases must be produced. The reaction can happen quickly because the oxygen source is containedwithin the reactants. This is because the oxygen is available immediately. The more oxygen available, that faster the reaction can happen. For the reaction to be exothermic, bonds in the molecules must be broken,causing heat energy to be released. How much energy released depends on thebond enthalpies between each atom. For example the N-O bond has an enthalpy of +214kJ mol-1, the N=O has+587kJ mol-1. When hot gases are produced in a confined space there is a big rise inpressure. When this happens very quickly, it can be called an explosion.

Propanone was in demand during the first world war and new methods ofproduction had to be invented. Previously propanone was produced by the drydistillation of wood excluding air. In 1914 Chaim Weizman used bacterial fermentation of starch from maize toproduce propanone. Later on, a lack of Maize resulted in the use of conkersusing the same process. This however was less efficient. Later, propanone was produced by passing propan-2-ol vapours over a coppercatalyst. The source of the propan-2-ol is propene, a result of crude oilcracking. 5. Safety during the development of these explosives was relatively poor,as some scientists would experiment in their own homes, despite workingwith dangerous and explosive chemicals. There were many accidents,including that of Nobels factory which resulted in the ban of explosivemanufacture near residential areas in Sweden. Those manufacturing some of these explosives also had illnesses such as NGhead where Nitroglycerine was produced. However, Nitroglycerine can be used beneficially in the treatment of anginapectoris. The production of TNT caused headaches, anaemia and skin irritation in theworkers. Nowadays there are strict regulations enforced by the Healthy and SafetyExecutive, which provides detailed information on dangers of explosives andprotection of workers against chemical effects.
