Energy transference at hypersonic velocities Free Essays

I’m pretty sure we have had this discussion before so I’ve got one of my old copycats from a previous thread. Force travels through solid objects at roughly the speed of sound in that object, if you force a piece of an object to move at greater than the speed of sound through that medium it will simply tear whatever is holding it together without transmitting force to the surrounding structure. His gives a kind of hole punch effect If the projectile Is moving faster than the speed of sound In the target. We will write a custom essay sample on Energy transference at hypersonic velocities or any similar topic only for you Order Now The maximum known speed of mound is about 1 km/s in diamond, given that a dreaded shot moves at about Kim/s it is safe to assume that armor anti going to do sit. Given the momentum behind the small slug it should remain above the speed of sound in diamond until (keg*Kim/s/km/s) the total mass of matter it has punched through reaches 5. 3 tones. Second, things heat up when they are compressed as given by the perfect gas law (at these energy densities it is close enough for our purposes despite everything being solid) so when the projectile gets compressed it heats up, if it heats up to the correct bevel it melts, vaporizes and turns into plasma, that depends on the energy densities present (FUSION). So when a solid slug hits the armor the first thing which will happen Is that the slug punches a hole clean through the armor, no if’s, no buts. Then the pressure wave begins to propagate through both the armor chunk which has been torn out and the projectile, the amount of pressure in this wave is so immensely fugue that the matter instantly becomes plasma shortly followed by becoming a angular fireball. The only question left is how far does the projectile reach inside the ship until you can top modeling It as a projectile and have to start modeling It as a nuke. He Irony here Is that armor essentially contains the fireball Inside the vessel Instead of keeping it on the outside. This is also why whippier shields are effective, the small layer of matter makes a hyper velocity impact under go the pressure induced explosion and become a far less damaging gas which Is then repelled by the actual armor of the vessel. Than weapons are a whole different ballgame. Nationally what comes out of a Than weapon can be considered a mass driver slug (the fact that it is molten doesn’t tater, the impact velocity is so far beyond the speed of sound in the target and projectile that it’s irrelevant) but in this case instead of being a CACM long cylinder or even a Javelin It is a long thin wire which probably only has a cross section measured In tenths of millimeters and a length In the hundreds of meters. ND punches a hole, the pressure wave propagates back through the projectile, as the pressure wave passes it explodes with the force of a nuclear weapon. So far normal. BUT Because the projectile is so long and traveling orders of magnitude faster than it’s peed of sound, once the front end explodes it leaves relatively clear (exploded) space for the next section of the projectile to pass through anus strike deeper into the target, Just like a pulsed laser or a multiple impact kinetic weapon like metal storm. His happens over and over and over again, the end effect is that a Than weapon will punch clean through a ship and out the other side which leaves a nice neat little hole.

Sun Also Rises And Hemingway Hero Essays - Literature, Fiction

Sun Also Rises And Hemingway Hero Prevalent among many of Ernest Hemingway's novels is the concept popularly known as the "Hemingway hero", an ideal character readily accepted by American readers as a "man's man". In The Sun Also Rises, four different men are compared and contrasted as they engage in some form of relationship with Lady Brett Ashley, a near-nymphomaniac Englishwoman who indulges in her passion for sex and control. Brett plans to marry her fiancee for superficial reasons, completely ruins one man emotionally and spiritually, separates from another to preserve the idea of their short-lived affair and to avoid self-destruction, and denies and disgraces the only man whom she loves most dearly. All her relationships occur in a period of months, as Brett either accepts or rejects certain values or traits of each man. Brett, as a dynamic and self-controlled woman, and her four love interests help demonstrate Hemingway's standard definition of a man and/or masculinity. Each man Brett has a relationship with in the novel possesses distinct qualities that enable Hemingway to explore what it is to truly be a man. The Hemingway man thus presented is a man of action, of self-discipline and self-reliance, and of strength and courage to confront all weaknesses, fears, failures, and even death. Jake Barnes, as the narrator and supposed hero of the novel, fell in love with Brett some years ago and is still powerfully and uncontrollably in love with her. However, Jake is unfortunately a casualty of the war, having been emasculated in a freak accident. Still adjusting to his impotence at the beginning of the novel, Jake has lost all power and desire to have sex. Because of this, Jake and Brett cannot be lovers and all attempts at a relationship that is sexually fulfilling are simply futile. Brett is a passionate, lustful woman who is driven by the most intimate and loving act two may share, something that Jake just cannot provide her with. Jake's emasculation only puts the two in a grandly ironic situation. Brett is an extremely passionate woman but is denied the first man she feels true love and admiration for. Jake has loved Brett for years and cannot have her because of his inability to have sex. It is obvious that their love is mutual when Jake tries to kiss Brett in their cab ride home: "'You mustn't. You must know. I can't stand it, that's all. Oh darling, please understand!', 'Don't you love me?', 'Love you? I simply turn all to jelly when you touch me'" (26, Ch. 4). This scene is indicative of their relationship as Jake and Brett hopelessly desire each other but realize the futility of further endeavors. Together, they have both tried to defy reality, but failed. Jake is frustrated by Brett's reappearance into his life and her confession that she is miserably unhappy. Jake asks Brett to go off with him to the country for bit: "'Couldn't we go off in the country for a while?', 'It wouldn't be any good. I'll go if you like. But I couldn't live quietly in the country. Not with my own true love', 'I know', 'Isn't it rotten? There isn't any use my telling you I love you', 'You know I love you', 'Let's not talk. Talking's all bilge'" (55, Ch. 7). Brett declines Jake's pointless attempt at being together. Both Brett and Jake know that any relationship beyond a friendship cannot be pursued. Jake is still adjusting to his impotence while Brett will not sacrifice a sexual relationship for the man she loves. Since Jake can never be Brett's lover, they are forced to create a new relationship for themselves, perhaps one far more dangerous than that of mere lovers - they have become best friends. This presents a great difficulty for Jake, because Brett's presence is both pleasurable and agonizing for him. Brett constantly reminds him of his handicap and thus Jake is challenged as a man in the deepest, most personal sense possible. After the departure of their first meeting, Jake feels miserable: "This was Brett, that I had felt like crying about. Then I thought of her walking up the street and of course in a little while I felt like hell again" (34, Ch. 4). Lady Brett Ashley serves as a challenge to a weakness Jake must confront. Since his war experience, Jake has attempted to reshape the man he is and the first step in doing this is to accept his impotence. Despite Brett's undeniable love for Jake, she is engaged to marry another.

Civil Disobedience vs. Sociology of the South essays

Civil Disobedience vs. Sociology of the South essays Civil Disobedience vs. Sociology of the South Examining two pieces of writing from 1800 US history, we see two writers with strong polar backgrounds agreeing on minor issues of the time. It is hard to find a common ground between Henry Thoreau and George Fitzhugh, but they share similar views toward government and its relationship with the masses. They opposed the government and wanted the people to dictate their wants to the government. Henry David Thoreau, writer, naturalist, and philosopher, was born in Concord, Massachusetts, in 1817. Thoreau became involved in the transcendentalist movement, a discipline promoting self-education and the development of the individual. Thoreau's most famous essay, Civil Disobedience (1849), was a result of an overnight visit in 1846 in a jail, when he refused to pay his taxes in protest against the Mexican War and the extension of slavery. Believing that his money should not go towards programs he did not believe in, Thoreau ended up in jail for one night. In Civil Disobedience, Thoreaus advocacy of civil disobedience as a means for the individual to protest those actions of his government that he considers unjust has had a wide-ranging impact. Emphasizing the magnitude and significance of individuality vs. conformity, Thoreau expresses a strong distaste for the interfering role of the government in peoples lives. His reasoning behind this is essentially that the government is always throwing up seemingly impossible obstacles to obstruct the path toward individual success. As a result of mankinds frustration at not being able to get around these obstacles, man instead marches in line at the governments bidding, believing only with the governments control will they be able to successfully plot the path to individual freedom. Thoreau found it ironic, however, that this supposed path to individual freedom was paved by traditional mindsets. Thoreau viewed the government as the ...

Normality and Normalcy

Normality and Normalcy Normality and Normalcy Normality and Normalcy By Maeve Maddox Audrey Bennett asks: Can normalcy and normality be used interchangeably? Both nouns derive from the adjective normal. normal: conforming to a standard; usual, typical, or expected. The adverb is normally. According to some speakers, normalcy is an abominable neologism to be avoided at all costs. This attitude is illustrated by this comment praising a writer for preferring normality over normalcy: A Nobel in Literature to you for writing â€Å"return to normality† instead of the ugly neologism â€Å"normalcy,† first popularized by Warren G. Harding. Actually, according to the OED, this particular neologism was around as early as 1857, nearly half a century before Harding used it in his campaign in 1920 when he promised a return to normalcy. The following examples are all from U.S. publications: After Opener, Giants Hoping for Normalcy For a man doing time on the yard, sports offer a touch of normality and tangible contact with his life outside. Pasternack hoping to bring normalcy to New Orleans Seventeen years later, my quest for normality had taken me through a career in journalism†¦ AFTER THE STORM; South Florida Staggers to Normality Evacuees Worry and Hope for Return to Normalcy Normalcy is not interchangeable with normality in some contexts. For example, in comparing an untypical condition to a typical condition, one would want to pair abnormality with normality and not normalcy. Although the form abnormalcy is showing up on the web and even in some dictionaries, its not in the OED, and it is not standard in American speech. Bottom line: Normalcy is well established and acceptable in standard American speech, although it is not interchangeable with normality in some contexts. Normality, on the other hand, suits every context in which the sense the state or condition of being normal is intended. Want to improve your English in five minutes a day?

ICT Effect on Teaching Term Paper Example | Topics and Well Written Essays - 3000 words

ICT Effect on Teaching - Term Paper Example Information Communication Technology (ICT) is an umbrella name that covers a range of applications and devices used for collection, analyzing, storage, retrieval, processing and transmission of information for instance radio, computer hardware and software, television, satellite systems, video conferencing software, and cell phones. These applications and devices have played a big role in how various sectors perform their functions due to their ability to improve communication, assessment of objects while reducing the time taken to achieve desired results. The modern ICT usage has been a driving force in the creation of a global village, which refers to the current situation where people communicate with each other across the world in real time. The importance of ICT usage in the contemporary world lies less in the technology itself than in its potential to facilitate higher levels of access to information and communication in areas that record low usage of the different technologica l applications and devices. As a consequence of the focus on access to technology, different countries have put in place special organizations.This basis for concern by relevant authorities that if not less technologically innovative areas are supported with necessary infrastructure to catch up, the continued technological advances experienced in the industrialized countries will only serve to worsen the existing situation where the economic gap between those with an ability to use technology and who do not have been rising.

Nietzsche's program for a new europe Assignment

Nietzsche's program for a new europe - Assignment Example Nietzsche advocated the idea of â€Å"New Europe†, a utopian concept that described Europe as a continent without national boundaries which is united not on the basis of a common economic benefit and financial guiding principle but by the aspiration to cultivate the Dionysian, his basic principles based on the Greek philosophies and concepts of totality (Deleuze, 12). His idea of a new Europe was inspired by the Jewish populace in Europe. For him, the Jewish represented his description of the spiritually and mentally exceptional creatures. Nietzsche believed that such spiritual could perform creatively in a set up devoid of national institutions. . For this reason Nietzsche bestowed the Jewish with such a crucial role in the formation of an extraterritorial and a supranational (Golomb and Wistrich, 12) continent of the future where their bountiful power will surge into the great spiritual persons and their works, which would ultimately act as an everlasting consecration for Eu rope. He believed that the Jewish would turn out to be the creator and originator of values and also the catalysts in the transfiguration of values. He believed that the feeling of extreme nationalism often comes in the way of creative and spiritual emancipation. Nietzsche’s idea of a New Europe is inspired and developed on the basis of several factors which include his philosophies, the cultural, political and social influences and also the spiritual aspects that have been mentioned above. Nietzsche was fascinated by the history of the Jewish people and it was a great source of mystery for him. He was enthralled by the pattern of the Jews in the Diaspora and their aptitude as well as their capability to create a successful spiritual and cultural empire in Europe not on the basis of any nation or territory. Despite their apparent political and physical limitation, he referred to the Jews as the

Analysis of Birches by Robert Frost Essay -- Birches Robert Frost Poet

Analysis of Birches by Robert Frost In the poem Birches by Robert Frost, Frost portrays the images of a child growing to adulthood through the symbolism of aging birch trees. Through these images readers are able to see the reality of the real world compared to their carefree childhood. The image of life through tribulation is the main focal point of the poem and the second point of the poem is if one could revert back to the simpler times of childhood. The language of the poem is entirely arranged through images, although it contains some diction it lacks sound devices, metaphors, and similes compared to other published works by Frost.   Ã‚  Ã‚  Ã‚  Ã‚  The first half of the poems’ images are of life, coming of age, and death. The first three lines in the poem represent the image of childhood and adulthood. â€Å"When I see birches bend to left and right Across the lines of straighter darker trees, I like to think some boy’s been swinging them.† Childhood is represented when the branches swing Frost thinks there is a boy swinging on them. Adulthood is represented by straighter darker trees because darker is a reference to older trees just by the nature of the color as compared to a birch tree which is white or light in color. â€Å"But swinging doesn't bend them down to stay. Ice storms do. Often you must have seen them Loaded with ice a sunny winter morning. After a rain. They click upon themselves As the breeze rises, and turn many-colored As the stir cracks and crazes their enamel....
