Charles Law Introduction In this lesson, we will investigate Charles Law, which relates changes in he temperature of a confined gas kept at a constant pressure to the volume of the gas. You will be introduced to another equation that determines the variation of gas volume with change in temperature. Discussion Jacques Charles was a French chemist famous for his experiments in ballooning. Instead of hot air, he used hydrogen gas to fill balloons that could stay afloat longer and travel farther. Figure 2. 1 Jacques Charles slaw/slaw. HTML Charles Law states that tort a given amount tot gas at constant pressure, the volume is directly proportional to the temperature in Kelvin, V a T.

Is Rap Music The Cause Of Violence Essays - Gangsta Rappers

Is Rap Music The Cause Of Violence? Is Rap Music the Cause of Violence? Since the late 1980's rap music has been called the Anti Christ in our culture, because of it's so-called influence in people's life. People swear up and down that the music is why people, specially the youth resort to violent crimes. I think by saying this they are trying to cover up the real truth by giving simple answers. Rap is defined as a style of popular music consisting of improvised rhymes performed to a rhythmic accompaniment. The first rap song was made in the late 70's, the songs were seven to eight minutes long and was mostly used in small clubs to dance to. It didn't really become popular until the early 80's. Over the years it has become mainstream music, everyone is listening to it. In the last four years rap made up 60% of music bought in stores in the United States. In 1989 a local group called N.W.A.(Niggaz Wit Attitudes) came from out of L.A. and changed rap, which was the start of Gangsta Rap. In their lyrics they talked about crime, street violence and killing. Once they were a huge hit, it caught on, and really that's when all this madness started. Everyone started rapping Gangsta style. More and more people started rapping about police brutality and killing people and with that crime rose to high levels. In my opinion it's not the artists or the record company's fault that crime rose. It's not their responsibility to look after every person who listens to their music. In all these years of rap though there are three people who took the most criticism from the public. Dr. Dre was one, after N.W.A. broke up he went on to do his own thing, and after he released The Chronic he became a star. He took rap to a higher level where it never been before and I think that scared a lot of people. He was rapping about drive by's, having sex with hundreds of women, drinking alcohol all day and so on. By this time the crime rate was sky high and a lot of people where looking for easy answers. It was mostly those few w ho just didn't like rap from the start that spoke out and tried to ban it. Most rappers loved the style Dr. Dre created, and so they tried to take the style and create something of their own. Along with Dr. Dre he helped a rising star Snoop Doggy Dog to become a big star by guest staring on his The Chronic album. Snoop released Doggy Style and it was a hit. His style similar to Dr. Dre made it a hit. It was his best-selling album to date. Congress tried every way they could to keep youth from listening to this music because they felt it was making them commit crimes. Snoop was charged not to long after his release for murder which he soon was found not guilty. They made a label for CD's and tapes that said Parental Advisory Explicit Lyrics which actually in my opinion didn't do too much. This way parents could be aware of the type of music their kids listen to and could choose if they would like to allow them to listen to it. If you sit down and think about it, when you buy a CD you by it because you want to listen to it, you don't really pay attention to that little label. Besides you see little kids no older then 11 walking around listening to Lil' Kim, Tupac, and all other rap artists cussing up a storm . . . what's with that? Why didn't the parents say anything about that, they have control over their children, yet critics and congress blame the rappers. The third man to take the most heat and who still continues to is Tupac Shakur. They say he was the best rapper alive and the most successful which I also believe is true. He has been in trouble with the law and public since his first album to even now after his death. He was arrested for numerous charges such as

Dramatic Structure Pulp Fiction Essays

Dramatic Structure Pulp Fiction Essays Dramatic Structure Pulp Fiction Paper Dramatic Structure Pulp Fiction Paper Essay Topic: Pulp Fiction Discuss a film that challenges the formulaic structure of the classic narrative. In particular, analyse approaches to Point of View and Time and Space and assess the extent to which the illusion of reality is maintained or disrupted.  In this essay I intend to look at Quentin Tarentinos 1994 Oscar winning film, Pulp Fiction. I will try to highlight and expose both the storyline and plot for their non-linear and unconventional structure. My aim therefore, is to show that Pulp Fiction is a prime example of a film that challenges the classic narrative, and in my opinion does it more convincingly than any other main stream film of my generation. Quentin Tarentino manages to meet the classic narrative demands of dominant cinema but also challenges its structure.  Pulp Fiction establishes itself as a post modern film and also remains a key part of dominant popular culture. The films idiosyncratic characteristics include fragmented storyline, eclectic dialogue, ironic and campy influences, unorthodox camerawork, and numerous pop culture references. We also see brands in the film that were common in the 1960s and 70s but no longer around today, this was again to bring a form of popular culture back to the forefront. Firstly I am going to look at the meaning of a classic narrative which is sometimes referred to as realist as suggested by one of the key characteristics, verisimilitude. The main characteristics of the classic narrative are diegesis or the creation of a fictional world, linearity of the plot or the cause and effect, continuity and the lack of disruption, narrative closure, verisimilitude and the psychological development of the characters. In the classical narrative, events in the story are organised around a basic structure of enigma and resolution. At the beginning of the story, an event may take place that disrupts a pre-existing equilibrium in the fictional world. Structural theorists such as Todorov and Freytag have both analysised narrative structure and perceive it to be one of cause and effect that is eventually resolved. Furthermore the realist aspects of the classical narrative are overlaid on this basic enigma-resolution structure, and typically operate on two different levels: firstly through the verisimilitude of the fictional world set up by the narrative rather than by documentary-style realism and secondly through the inscription of human agency within the process of the narrative. The plot basically tells us of the interwoven lives of several characters who all experience their own difficulties and discissions that have to be made. Vincent Vega and Jules Winnfield are two hit-men on the hunt for a briefcase whose contents were stolen from their boss, Marsellus Wallace. They run into a few unexpected detours along the road. Marsellus is out of town, and hes gotten Vincent to take care of his wife, Mia. That is, take her out for a night on the town. Things go smoothly until one of them makes a huge error. Butch Coolidge is a boxer whos been approached by Marsellus and been told to throw his latest fight. When Butch ends up killing the other boxer, he must escape Marsellus. Pumpkin and Honey Bunny are two thieves who have decided to rob the restaurant theyre currently eating at. But the restaurant doesnt turn out to be as easy as the other places theyve robbed. All these stories were written and told in a non-chronological order, we find a fragmented storyline, unorthodox camera work and numerous pop culture references, all challenging the classic narrative we come to expect from a main stream film. The films title and advert/cover refers to the pulp magazines popular during the mid-20th century, renowned for their strong graphic nature. The film as a whole can be broken up into six major parts, we do see within these parts a beginning, middle and an end for the multiple stories and characters, it is not clear however, where these elements fit in. Also we find that there is no unified but a multiple narrative, as each character shares with us there own idea of resolution and what they are trying to achieve during the film. The itself is well known for its cross cutting between stories, characters, time and space, all acting as devices to challenge the Todorov analysis of a classic structure. The opening shot is the dictionary definition of the word pulp followed by the reference to the magazines and their strong graphic nature. This is there to tell us immediately what to expect from the rest of the film.  The first part of the film, The Diner part 1, introduces us to a pair of petty crooks drinking coffee and talking about their aspirations and achievements. At this point in the film we dont know there names just that their occupation is holding up shops. Straight away we see intertexuality of a crime genre just from the dialogue used.
