Guy Montag Character Analysis - 980 Words

In the novel Fahrenheit 451 by Ray Bradbury, the main character Guy Montag can be described as being on a journey. Throughout the whole story he drastically changes both mentally and physically. Montag lives in a corrupt society, where they believe in suppressing knowledge. In the novel, Guy is breaking away from the popular views, and forming his own opinions on the government. In his journey to his true self he hits many major milestones and realizations. A few are 1. He is not happy in his current life, and feels the need to explore and learn about other rebels like him. 2. Montag steals a book, which were banned at the time 3. He kills his boss in a final argument. These changes form a new Montag, a Montag that defies the rules and†¦show more content†¦This is such a big milestone because it was the first root, the first rebel thought that would eventually bring him down a path in which he could never return from. After Montag had been self reflecting he came to a conclusion that he needed to steal a book. His outlook on life had changed and he wanted to see what he had been missing all of the years he was a firefighter. He wanted to find out why books were banned, and what they hid beneath top-secret covers. At this major point in the story Montag is burning a house down that was said to have books hidden inside. Although he had been burning houses for years, and he was supposed to go about it normally, he was appalled. Seeing his job in the light made him feel shocked and and disgusted by the people he used to call his friends. He takes it upon himself to steal a book from the house and bring it home with him. â€Å"Montag felt the hidden book pound like a heart against his chest. ‘Go on.’ Said the woman, and Montag felt himself back away and out the door, after Beatty, down the steps, across the lawn, where the path of kerosene lay like the track of some evil snail.† Thi s quote proves that this is a big milestone in the story. It shows that Montag is actually going through with stealing a book. He believes in knowledge enough so much that he will break a law to expose the government. Montag is now determined and has his mind set.

Essay on Personality and Personal Growth - 796 Words

Personality and Personal Growth â€Å"An integral being knows without going, sees without looking and accomplishes without doing† – Lao Tzu The text book definition of Personality is an individual’s unique pattern of thoughts, feelings and behaviors that persist over time and across situations. I agree with this idea that a personality is what makes all of us who we are. I believe that a personality is a combination of innate characteristics that everyone is born with and the sum of total life experiences. I believe that a personality is a portrayal of an individual’s reality. The way that an individual walks, talks, speaks and even the career path that they choose to go on is all a reflection of their personality. I believe that†¦show more content†¦Like my niece teaching me to slow down and look at life more open minded and less judgmental, I also teach her about the responsibilities of life, I guess you could say that we teach each other to find a happy medium. My beliefs can be summarized as follows 1. You must always live your life to the fullest, 2. Make mistakes because that is the only way that you are going to learn, and grow 3. In order to find happiness one must first suffer to discover what is in front of them. These are only three that I found but in my opinion there are many more. I believe that an individual’s growth is determined on the way that they choose to live their life. All beings are given a choice, a fork in the road to follow. Once you have chosen the road to take then the lessons that you come upon are the ones that you are meant to learn. My mom always says to me when I get frustrated that I made the choice to live the life that I am living. The problems that I encounter during this lifetime are the ones that I have to encounter in order to find true happiness. I was once told that when any person is about to come to earth they sign a contract stating that they have different lessons to learn in order to find true happiness, if they do not learn the lessons that they are meant to learn then the challenges to teach them will follow them through to the next lifetimeShow MoreRelatedAnnotated Bibliography On The Implications Of Psychopathic Personality Traits For Successful And Unsuccessful Political Leadership1312 Words   |  6 PagesImplic ations of psychopathic Personality traits for successful and unsuccessful political leadership.

Usability Evaluation and Recommendations For Sixties Press Poetry Magazine IT3210 – Web Systems and Technologies John Winko Capella University Introduction This paper will propose a website redesign for Sixties Press Poetry Magazine located at http://www. sixtiespress. co. We will write a custom essay sample on Usability Evaluation and Recommendations or any similar topic only for you Order Now uk. The site is owned by Thushari Williams according to Whois and the primary purpose of the site is curating/collecting/publishing various poets’ work that relates to a 1960’s era theme. There does not appear to be any corporate backing to the publication or syndication of any sort. After reading through the tirade of obfuscated source code, it is a safe assumption the site was initially done in an older version of Microsoft Word then saved as a webpage. Site improvements will be recommended based off of a blended heuristic matrix found in appendix 1 formed from Search Engine Journal and usereffect. com. Table of Contents Introduction2 Table of Contents3 Identity4 Structure and layout4 Information architecture and site navigation5 Use of visual elements6 Usability7 Accessibility7 Conclusion8 References9 Appendix 1 – Heuristic Usability Questionnaire10 Appendix 2 – Site Navigation and Use Case Scenario14 Identity The website http://www. sixtiespress. co. uk is for a magazine called â€Å"Sixties Press Poetry†. The site has a logo that is replicated at the top of every page but does not have a clear tag line to indicate the purpose of the site. A user has to glean the fact the site is a collaboration of different authors generating 60’s themed poetry from menu items and the body content on the main page. There is not a specific â€Å"About Us† page anywhere on the site and the only contact information is in a small section on the bottom left portion of the homepage. The target audience is anyone seeking poetry with a 60’s theme and critical of poetry publishing processes in place in today’s society. Additionally, there are options for purchasing hard-print magazines chosen from a catalog. These facts are not readily ascertained from the overload of content found on the homepage. The site redesign will give a more concise description of the site’s purpose on the homepage as well as a brief tagline. The amount of content on the homepage will be trimmed down so that the site’s identity and purpose are more readily apparent. Structure and layout From a layout standpoint, the overall wrapping of the body of each page on the site changes with the homepage having a wrapped width of 836px while the poetry page has a fixed width of 989px. This inconsistency leads to extra whitespace for some pages while less or none for other pages based on the user’s browser resolution and size. The body content is also left aligned so all extra whitespace is shown on the right which detracts from easier focus on the central content of pages. All of the pages show the site logo at the top followed by a navigation menu. This is considered good design and will not be changed structurally for the site redesign. The homepage uses a 3 column layout while other pages vary from 1 to 3 columns for their layouts. Columns are not distinctive in their content and are structurally disruptive giving the appearance of â€Å"cramming† information into a tighter space. There are apparent sections within the homepage body to delineate different parts of the site but no form of clean navigation to identify a relevant section quickly aside from consolidated coloring for each section. Pages are laid out with tables using blank paragraph tags to add space for formatting. This creates a very different viewing experience across different browsers as each medium has a different set of default values for spacing padding etc. The table widths also vary from page to page and section to section creating different alignments from the fixed position formatting used. The site redesign will eliminate the table structure for layout and use floated elements (divisions) to accomplish a more fluid layout. Column structure will follow designs set forth in Appendix 2. Information architecture and site navigation The entire site is broken into about 8 pages branching from the homepage with numerous anchor links used to navigate long pages of poetry. The actual content pages are extremely long, to the point the thumb scroll becomes it’s minimize size at 1920Ãâ€"1080 screen resolution. Given the breadth of information on pages such as â€Å"Poetry. hml†, the architecture could be improved by breaking out pages by author and/or subject. Individual hyperlinks do follow a consistent pattern of being underlined and a hand mouse pointer to indicate that clicking the link is actionable. The actual ordering information for hard print magazines is hidden in a catalog link not listed on the main navigation bar. There are also pages for internal authors that are only accessible from the main page and are not descriptive to being a collection of a specific the respective authors work. The site redesign will encompass using a more description navigation menu to better direct the user if they wish to purchase anything the site has to offer as well as a more intuitive menu and architecture for collective works by author. Use of visual elements For a website decided to poetry, the decisions for color and contrast do not follow a typical 60’s theme let alone theming for easier reading. Typically 60’s themed colors include Turquoise, Jade, and Mint Green amongst others (McEvoy, n. d. ), starkly contrasted to the dark red on black shown on the homepage. The â€Å"important† headings all have a random color with an â€Å"XOR’d† background while the menu has the same variation of random colors with a pitch black background. Each subsection of content within the body of the homepage is a different color with additional areas having an offset color scheme. The under-contrasted pages would make viewing the site very difficult for someone that is color blind The background wallpaper on each page has a subtle 60’s them but does not contrast well with the multi-color text of poetry passages or content in general. The font size and space are adequate but the font face itself detracts from the aesthetics of the pages’ content. The majority of the block text uses a â€Å"Black Chancery† font face which is not considered web safe and the site would be better suited to use a standard serif font. An exception can be made to allow for an embedded font such as Bellbottom Laser (Lorvad, 1991) to be used for adding flare to title headings. Usability Rather than using the html pseudo element â€Å"copy;† the designer made a picture of their copyright statement and it appears they expanded its size from the original distorting the image quality. The site redesign will use text in place of images used to accomplish to the same task. The picture of Barry Tebb, one of the authors, requires a java applet to run only to have a non-value added effect of water droplets on a grainy photo. The site redesign will remove the unnecessary applet and use a static image instead. Additionally, the site logo will be linked directly to the homepage making navigation easier. There is a text area on the homepage that contains about 5 paragraphs of text and requires scrolling in a very narrow window. This will be revised into a more useable text block following the same design pattern as the rest of the site. With the exception of archives page, text blocks are limited to less than 80 characters per line making reading easier. Although links are properly anchored and are consistent with being underlined, the redesign will consolidate link colors to preserve thematic relevance. The actual number of links on the homepage will be reduced as its current form has more links than descriptive content detracting from understanding the purpose of a homepage. Accessibility A W3C validation of the homepage discovered over 130 HTML coding errors and all of the styles were made inline without any use of external CSS. (W3C, 2012) None of the images on the site have alt text to failover if the image failed to load. There is not a concise separation between navigation and content within the code as the home used a table row and other pages used paragraphs as the separating entities. By eliminating the table structure of pages, the site redesign will properly code in HTML5/CSS3 ensuring the viewing experience is consistent across the majority of browsers. The site uses a JavaScript based pop-out menu to assist navigating large pages of poetry but there are numerous compatibility issues that occur. The pop-out menu rests about halfway down the screen and overlaps the body content both when expanded and collapsed. The menu bar beneath the logo is in an intuitive place but â€Å"jumps around† when navigating different pages since the formatting rules vary between browsers. The site redesign will eliminate the JavaScript based pop-out menu and will instead use a floating sub-menu for individual sections. Conclusion The majority of changes to the site will be thematic in nature, updating the color scheme and positioning. Additional changes will be made to improve the site’s identity starting with revising the homepage and including an â€Å"About Us† page to further expand the site’s purpose. HTML and CSS coding standards and practices will be strictly adhered to ensuring compatibility and proper viewing experience across major browsers. References Cumbrowski, C.

Are links labeled with anchor text that provides a clear indication of where they lead? Yes. 2. Depth – what is the maximum number of clicks it takes to reach a page within the depths of the site? All pages are a single click away from the homepage (2 clicks if including anchoring from the menu). Given the amount of content on the site it would be more manageable to have a 3 click architecture to more concisely filter and arrange content (by author/by subject). 3. If a splash screen or navigation feature is provided in a Java/JavaScript/Flash format, is a text-based alternative also available? Yes, a JavaScript pop out menu is feature on long pages of poetry and a text version is available at the top of the page. 4. Do clickable items stylistically indicate that they are clickable? Yes, all items that are underlined are linked to some content and the mouse pointer changes to a hand to indicate that the click will be actionable. 5. How intuitive is it to navigate? Are signs obvious or obscured? In a general sense the navigation is intuitive but far from consistent with the layout changes between different pages. The pop-out menu is intuitive in IE but not in other browsers (actual clickable area is not visible). 6. Main navigation is easily identifiable. Mostly yes, however there is a page that contains revenue generation from ordering magazine that is not shown in the navigation bar or easily identifiable. Additionally there are pages that are specific to internal authors that are only accessible from the main page. 7. Navigation labels are clear concise. Textually relevant yes but thematically difficult to read. 8. Number of buttons/links is reasonable. No, there are links to too many different areas on the homepage detracting from being concise. The homepage itself has more link than actual content. 9. Company logo is linked to home? page. No. 10. Links are consistent easy to identify. All links are underlined but thematically change very regularly from size and color. An exception exists for the clickable area for each of the links, clicking to high on the text has no effect. Accessibility 1. Is content structurally separate from navigational elements? The navigation menu on the home page is separated from other content by a tr tag but on subsequent pages is contained in a p tag. There is not a concise separation between navigation and content. 2. Is the website cross-browser compatible? No. The layout is achieved using tables and paragraph blanks and the viewing experience was different between Firefox, Chrome and IE. 3. How compliant is the website with W3C coding standards? Valid HTML/CSS? No, a W3C validation resulted in over 130 errors. The pages only contain inline styles with no external or embedded CSS. 4. Are ‘alt’ tags in place on all significant images? No, there are not alt tags used for any images. 5. Are text-based alternatives in place to convey essential information if this is featured within images or multimedia files? No, on top of alt text being absent, the java applet containing a photo on the main page does not fail safely and left as an empty area. 6. Site load? time is reasonable? Yes, there are very few pictures and most pages consist primarily of text in the form of poems/poetry. . Adequate text? to? background contrast? No. The featured articles page has text color very close to the background color while the navigation items are too contrasted in difference. 8. Flash add? ons are used sparingly. Yes, but the sole java applet add-on used has no specific utility or purpose. The JavaScript pop-out menu does not load correctly across all browsers and is completely cut off from use in Chrome and Firefox. 9. Site has custom not? found/404 page. No. (Requires a server side change so not applicable) Identity 1. Company logo is prominently placed. Yes 2. Clear statement of PURPOSE of the site? Purpose does not become clear within a few seconds without reading much or no text copy at all. Assumptions have to be made from the text in the logo and menu to find out it is a magazine about poetry. 3. Who is the target audience? The site is meant for anyone seeking 60’s era poetry and those looking to purchase a copy of the print magazine. 4. Tagline makes company’s purpose clear. No tagline present. It is assumed the site is about poetry after reading through the body content. . Home? page is digestible in 5 seconds. No, there are multiple vectors the eyes are drawn to which makes getting an overall view more difficult. There are laundry lists of authors, selected readings and selected sections for each subpage of the site on the homepage. 6. Clear path to company information. No specific â€Å"About Us† page listed and had to specifically perform a WHOIS search to determine t rue site ownership. The homepage does contain a clause that specifies original copyright remains with respective authors and images were courtesy of Leeds Library. . Clear path to contact information? Not really, there are contact details on the bottom left corner of the homepage but not specifically listed as official site contact. Design 1. Is the site’s design aesthetically appealing? No, the color scheme alone makes the site very unappealing. The stark contrasts set against the â€Å"swirling† background makes focusing difficult and the left aligned nature draws too much attention to the whitespace left on the right side of the screen. 2. Are the colors used harmonious and logically related? No, colors seem extremely random in nature although they are logically related to sections (one color for each section). 3. Are the color choices visually accessible? No, some parts have color themes that are too starkly contrasted while others are not contrasted enough to allow easier reading. It would be very difficult for someone color blind to absorb a lot of the content. 4. Is the design audience appropriate? Yes, the font size is appropriate for older audiences and those wishing to â€Å"retro† to 60’s content. 5. Font size/spacing is easy to read? Font size and spacing is adequate. 6. Readability and appropriate type face? No, there are multiple different fonts used and the specific fonts do not add to the readability or theme of the website. The â€Å"Black Chancery† font use predominately for block text is not considering a web safe font. Content 1. Is the website copy succinct but informative? There are continuous sections of poetry that detracts from being â€Å"succinct† but the content only design can be considered informative. 2. Does the copywriting style suit the website’s purpose and ‘speak’ to its target audience? There is an attempt at using vibrant colors resembling 60’s design but that attempt falls short of effectively speaking this to the audience. 3. Are bodies of text constrained to 80 characters per line? Most pages do, however, the Archives page does not and has text that spans the entire width of the page. 4. Can text be resized through the browser or do CSS settings restrict size alteration? Text can be resized at different resolutions without detriment. 5. Is the contrast between text and its background color sufficient to make reading easy on the eyes? No, the color scheme heavily detracts from easier reading (see design considerations) 6. Is text broken into small, readable chunks and highlighted using headings, sub-headings and emphasis features where appropriate to assist in skimming? Yes. 7. Do you have testimonials and publish them on the site? There is a â€Å"Reviews† page that acts as a testimonials or critical acclaim although the mix of good and bad reviews is not concise. 8. Do you update the content regularly and don’t live by the phrase â€Å"set it and forget it†? Content has not been updated since 2007 so it appears the content has been â€Å"forgotten†. . Major headings are clear descriptive. Yes 10. Styles colors are consistent. No, see previous comments on color scheme. 11. Emphasis (bold, etc. ) is used sparingly. No, although there is an absence of b and em tags, emphasis is placed by using the stark contrast for header items in the form of color. 12. Ads pop? ups are unobtrusive. No, the menu pop-out overrides the underlying text. 13. Main copy is concise explanatory. Mostly, yes. As a poetry site each individual article accomplishes its own purpose although the particular arrangements used are not self-explanatory. 4. HTML page titles are explanatory. Yes.

You have things like: The vacuum of space Heat managementproblems The difficulty of re-entry Orbital mechanics Micrometeorites and spacedebris Cosmic and solar radiation Restroom facilities in a weightlessenvironment And so on But the biggest problem of all is harnessing enoughenergy simply to get a spaceship off the ground. That is where rocket enginescome in. Rocket engines are on the one hand so simple that you can build and flyyour own model rockets very inexpensively (see the links at the bottom of thepage for details). On the other hand, rocket engines (and their fuel systems)are so complicated that only two countries have actually ever put people inorbit. In this edition of How Stuff Works we will look at rocket engines tounderstand h ow they work, as well as to understand some of the complexity. TheBasics When most people think about motors or engines, they think aboutrotation. For example, a reciprocating gasoline engine in a car producesrotational energy to drive the wheels. An electric motor produces rotationalenergy to drive a fan or spin a disk. A steam engine is used to do the samething, as is a steam turbine and most gas turbines. Rocket engines arefundamentally different. Rocket engines are reaction engines. The basicprinciple driving a rocket engine is the famous Newtonian principle thatto every action there is an equal and opposite reaction. A rocketengine is throwing mass in one direction and benefiting from the reaction thatoccurs in the other direction as a result. This concept of throwing massand benefiting from the reaction can be hard to grasp at first, becausethat does not seem to be what is happening. Rocket engines seem to be aboutflames and noise and pressure, not throwing things. So lets loo k ata few examples to get a better picture of reality: If you have ever shot ashotgun, especially a big 12 guage shot gun, then you know that it has a lot ofkick. That is, when you shoot the gun it kicks yourshoulder back with a great deal of force. That kick is a reaction. A shotgun isshooting about an ounce of metal in one direction at about 700 miles per hour. Therefore your shoulder gets hit with the reaction. If you were wearing rollerskates or standing on a skate board when you shot the gun, then the gun would beacting like a rocket engine and you would react by rolling in the oppositedirection. If you have ever seen a big fire hose spraying water, you may havenoticed that it takes a lot of strength to hold the hose (sometimes you will seetwo or three firemen holding the hose). The hose is acting like a rocket engine. The hose is throwing water in one direction, and the firemen are using theirstrength and weight to counteract the reaction. If they were to let go of thehose, it would thrash around with tremendous force. If the firemen were allstanding on skateboards, the hose would propel them backwards at great speed!When you blow up a balloon and let it go so it flies all over the room beforerunning out of air, you have created a rocket engine. In this case, what isbeing thrown is the air molecules inside the balloon. Many people believe thatair molecules dont weigh anything, but they do (see the page on helium to get abetter picture of the weight of air). When you throw them out the nozzle of aballoon the rest of the balloon reacts in the opposite direction. Imagine thefollowing situation. Lets say that you are wearing a space suit and you arefloating in space beside the space shuttle. You happen to have in your hand abaseball. If you throw the baseball, your body will react by moving away in th eopposite direction. The thing that controls the speed at which your body movesaway is the weight of the baseball that you throw and the amount of accelerationthat you apply to it. Mass multiplied by acceleration is force (f = m * a). Whatever force you apply to the baseball will be equalized by an identicalreaction force applied to your body (m * a = m * a). So lets say that thebaseball weighs 1 pound and your body plus the space suit weighs 100 pounds. Youthrow the baseball away at a speed of 32 feet per second (21 MPH). That is tosay, you accelerate the baseball with your arm so that it obtains a velocity of21 MPH. What you had to do is accelerate the one pound baseball to 21 MPH. Yourbody reacts, but it weights 100 times more than the baseball. Therefore it movesaway at 1/100th the velocity, or 0.32 feet per second (0.21 MPH). If you want togenerate more thrust from your baseball, you have two options. You can eitherthrow a heavier baseball (increase the mass), or you can throw the baseballfaster (increasing the acceleration on it), or you can throw a number ofbaseballs one after another (which is just another way of increasing the mass). Oedipus's Crime EssayIn the case of the SRBs, it gives the engine high initial thrust and lowerthrust in the middle of the flight. Solid-fuel rocket engines have threeimportant advantages: Simplicity Low cost Safety They also have twodisadvantages: Thrust cannot be controlled Once ignited, the engine cannot bestopped or restarted The disadvantages mean that solid-fuel rockets are usefulfor short-lifetime tasks (like missiles), or for booster systems. When you needto be able to control the engine, you must use a liquid propellant system. Liquid Propellant Rockets In 1926, Robert Goddard tested the first liquidpropellant rocket engine. His engine used gasoline and liquid oxygen. He alsoworked on and solved a number of fundamental problems in rocket engine design,including pumping mechanisms, cooling strategies and steering arrangements. These problems are what make liquid propellant rockets so complicated. The basicidea is simple. In most liquid propellant rocket engines, a fuel and an oxidizer(for example, gasoline and liquid oxygen) are pumped into a combustion chamber. There they burn to create a high-pressure and high-velocity stream of hot gases. These gases flow through a nozzle which accelerates them further (5,000 to10,000 MPH exit velocities being typical), and then leave the engine. Thefollowing highly simplified diagram shows you the basic components. This diagramdoes not show the actual complexities of a typical engine (see some of the linksat the bottom of the page for good images and descriptions of real engines). Forexample, it is normal for either the fuel of the oxidizer to be a cold liquefiedgas like liquid hydrogen or liquid oxygen. One of the big problems in a liquidpropellant rocket engine is cooling the combustion chamber and nozzle, so thecryogenic liquids are first circulated around the super-heated parts to coolthem. The pumps have to generate extremely high pressures in order to overcomethe pressure that the burning fuel creates in the combustion chamber. The mainengines in the Space Shuttle actually use two pumping stages and burn fuel todrive the second stage pumps. All of this pumping and cooling makes a typicalliquid propellant engine look more like a plumbing project gone haywire thananything else look at the engines on this page to see what I mean. All kindsof fuel combinations get used in liquid propellant rocket engines. For example:Liquid hydrogen and liquid oxygen used in the Space Shuttle main enginesGasoline and liquid oxygen used in Goddards early rockets Kerosene and liquidoxygen used on the first stage of the large Saturn V boosters in the Apolloprogram Alcohol and Liquid Oxygen used in the German V2 rockets Nitrogentetroxide (NTO)/monomethyl hydrazine (MMH) used in the Cassini engines OtherPossibilities We are accustomed to seeing chemical rocket engines that burntheir fuel to generate thrust. There are many other ways to generate thrusthowever. Any system that throws mass would do. If you could figure out a way toaccelerate baseballs to extremely high speeds, you would have a viable rocketengine. The only problem with such an approach would be the baseballexha ust (high-speed baseballs at that) left streaming throughspace. This small problem causes rocket engine designers to favor gases for theexhaust product. Many rocket engines are very small. For example, attitudethrusters on satellites dont need to produce much thrust. One common enginedesign found on satellites uses no fuel at all pressurizednitrogen thrusters simply blow nitrogen gas from a tank through a nozzle. Thrusters like these kept Skylab in orbit, and are also used on the shuttlesmanned maneuvering system. New engine designs are trying to find ways toaccelerate ions or atomic particles to extremely high speeds to create thrustmore efficiently. NASAs Deep Space-1 spacecraft will be the first to use ionengines for propulsion. See this page for additional discussion of plasma andion engines. This article discusses a number of other alternatives. Science
