Quantum vs. Classical Mechanics :: essays research papers

Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated, Classical mechanics can still be used for many everyday problems with bigger and slower moving objects. However, when dealing with extremely fast moving or small subatomic particles a Classical approach will not produce sufficiently accurate results as was the case around the 19th century.   Ã‚  Ã‚  Ã‚  Ã‚  Difficulties with the Classical mechanics theory came right around the 19th century. First was the Ultraviolet Catastrophe. Experimental data when testing blackbody radiation was found to be inconsistent with Classical mechanics. The data showed that as the wavelength of the incoming radiation approaches zero, the amount of energy being radiated also approaches zero, whereas Classical mechanics says the emitted energy is infinite. The second difficulty with the theory was its inability to correctly describe the photoelectric effect. The photoelectric effect says that photons from a surface are released when light hits it. Classical mechanics says that electrons will be emitted from a metal by light waves with any frequency as long as the intensity of the light is strong enough, and even if it is weak over a long enough period of time electrons will eventually be emitted. The theory was proved incorrect after experiments showed that light under certain frequencies did not produce the photoelectric effect on the metal, which meant that the emitting of electrons is related not to intensity but the waves frequency. A new string of mechanics, Quantum mechanics, was created in order to resolve the incompatibilities of Classical Mechanics. A main difference between the two fields of mechanics is the make up of the atom. In Quantum mechanics electrons in an atom are outside of the nucleus in specific orbitals around the nucleus that they can jump from one to another only when a specific energy level is reached, and can never be in-between the specific orbitals. Also Quantum mechanics says that a photon is released only when an electron jumps from a higher energy level to a lower energy level, or a higher energy orbital to a lower energy orbital. Classical mechanics, contradicting this, says that an atom is constantly emitting radiation. Quantum mechanics describes light as both a wave and a particle, depending on the situation.

Body and gender representation Essay

The general public is also the intended audience for this movie. Here, woman is represented as a jobless, single mother, a situation that many women in society find themselves in. Out of desperation, Brokovich presses her lawyer to give her a job in his firm and was given a clerical position. However, she was not treated with seriousness because she did not conform to the dress and manners required of an office employee. In the course of her work, she came across information about a company depositing toxic chemicals that polluted the local water supply. She takes an active role in building a case against the company. Gender representation is consistent with cultural norms in that women are mothers whose role is to nurture their children. However, the strength, assertiveness, intelligence, efforts to control and direct life and active involvement in social issues portrayed by Brokovich departs from cultural norms which dictate that women be passive, dependent or should focus their time on domestic affairs. This female representation is very positive. Les Miserables (1998) An adaptation of the French classic novel, the movie is again for general patronage. In line with the novel, the film portrays an ex-convict Jean Valjean who commits crime but soon establishes a new life under a new identity. He builds a business employing the poor and disadvantaged and upon the dying wishes of a prostitute whom he defended from unjust imprisonment and whom he took care of while sick, raises her daughter as his own. He does everything to ensure her safety, education, home, social standing and financial security. Gender representation in this film is positive. Male representation moves away from the cultural norm of detached and not domestically inclined father. Here, Valjean takes on the nurturing role, selfless with a strong stance against the oppression of both women and men. However, this was not carried out in the traditional manner of knight in shining armor or as a male holding a position of power but rather as a struggling person helping his fellow poor. The representation of women was through Fantine, an unwed mother whom poverty forced into prostitution and her daughter who was enslaved and abused by the family to whom she was initially entrusted. The woman in this family was particularly cruel. This portrayal of women as traditionally helpless, discriminated and taken advantage of but who can also take on the role of oppressor provides a realistic view of the variety of roles that women take on in society. Pictures 1. This photo in a magazine’s swim suit edition portrays femininity in terms of physical beauty. This is defined as flawless hair, clear skin with an excellent tone, slimness and curves. This representation is consistent with society and male’s standard of femininity and beauty to which a woman’s worth may be judged. Because women’s bodies are different and the average woman does not look like her at all, its impact on women is negative. It leads them to become dissatisfied with their bodies which results in a poor body image and low self-esteem. It also reinforces women’s gender roles of preoccupation with beauty. In regarding themselves as defective and in cultivating the desire to attain the model’s looks and body, women will spend much time, effort and money. The target audience of the magazine includes teen-agers and young women who are potential buyers of the product being advertised. 2. The strong, muscular and aggressive stance of the male in this photo, which appeared in a magazine for women, represents current cultural norms regarding masculinity which encompasses male gender roles of taking the active part, dominant, capable and powerful. It reflects traditional views that men cannot be soft, weak, puny or vulnerable. Men are affected negatively by this representation because it also establishes a standard that they have to conform to. It establishes that these physical characteristics are what women would find appealing but like women, men are also different. Hence, those men who do not possess the physical attributes portrayed by this model will feel insecure and would also attempt to build their physique and the matching attitude. 3. The intended audience for this picture is also women. Aside from portraying femininity in terms of beauty, femininity is also represented as youth and sensuality. The dress, the body parts revealed and position of the model are both sexy and seductive. It reflects the traditional view of women as sex objects and their role as a source of male sexual fantasy and satisfaction. Similarly, this representation is negative because it implies that in order to be desired by men, women have to have the proper physical attributes of breasts, legs and buttocks such as portrayed. It impacts most especially on the self-esteem of older women since age diminishes the physical characteristics perceived as desirable. Wrinkles, age spots and decreasing muscle tone, which occur within the normal course of an older woman’s life, are now regarded as their adversary.

Marketing Plan Final Paper - 4426 Words

MKT/421 April 8, 2013 Ken Metz Marketing Plan: Final Paper and Presentation Fisher Price produced a new product to teach children how to tie shoes. In this paper, there is information about who Fisher Price is a description of the new product, their marketing mix method and a SWOTT analysis of the product. Fisher-Price, Inc. was founded in 1930 and is based in East Aurora, New York. It all started out when Herman Fisher, Irving Price, and Helen Schelle created the toy company and brought 16 wooden toys to The International Toy Fair in New York City. Those first toys became very popular and became the hallmarks of Fisher Price. As of 1993, Fisher Price operates as a subsidiary of the organization Mattel Inc., the worldwide leader in†¦show more content†¦Every toy that has been made must pass through the Play Lab process. The results that are analyzed from the Play Lab play a crucial role in the expansion and redesign of the toys. Another market research strategy is meeting with parent in focus group-like settings. They also conduct at home research testing. Fisher-Price compensates the parents for individual parent talk sessions and for in-home testing of their products. When the at-home products are returned a survey must be filled out about the product that was tested (Pisan i, 2006). Product testing, quality assurance, and research and development are important when considering how to market The Talking Shoe. The company must understand whom they are designing the product for and how to reach that audience effectively, because without targeted marketing it is very easy to burn capital without gaining sales. Marketing can help create ideas for product usage in the consumer mind, as well as increase consumer interest, loyalty and spending. TV, digital, print and radio advertising have the most reach and cost the most money. The Talking Shoe must educate the parents to encourage them to purchase the product. Because the aim of the product is to lessen frustration for children and making teaching easier for parents, an educational visual approach, printed visual image of use, and digital combination would be the most effective methods of message delivery.
