A World of Art Essay Example | Topics and Well Written Essays - 1500 words - 1

A World of Art - Essay Example For instance, the Greeks invented three architectural systems called Doric, Ionic and Corinthian that stood for various meanings (Architecture, 2011). The Doric order, the column a sturdy and plain appearance, was used for the Parthenon in the capitol, and it incorporated worship of Athena, the Greek goddess of wisdom (Architecture, 2011). The point of using the Doric order was to symbolize order and harmony, which coincides with the goddess Athena. Architecture was not the only form of art that reflected religion. Sculptures were vastly popular in ancient Greece and they often times were figures of gods and goddesses like Zeus, even heroes and events were created to mirror religion. In the Christian era, art and architecture were not very different from Greece in how religion was portrayed. Before Christianity was universally accepted, art had to be hidden. These artists did not focus on perfection and beauty as did those that produced Greek art because they sought importance in tra nsforming their beliefs and teaching the Christian religion to others (Early, 2007). Sculptures were rarely seen, and unlike Greek architecture, Christian architecture was bland and unadorned in comparison (Early, 2007). However, the interiors were rich with furnishings- marble, mosaics, hangings, etc. as if to show that Christianity is not about always being beautiful and showy, but faith is set at the hearth like the heart and done with the family. 2. a. Mannerism: This era was set in before the baroque period, and it was European art that occurred around 1520-1580 in Italy Renaissance (Sayre, 2007). The focal term was harmony, which was illustrated through naturalistic paintings, i.e. paintings that were universally recognized as meaning the same thing to various people. Leonardo da Vinci and Raphael were famous artists of this era (Sayre, 2007). b. Baroque: Following the mannerism era, baroque came about in the late 16th-early 18th century throughout Europe (Sayre, 2007). It is a form of art that reflects religious themes as well as express power in aristocracy society. Lavish palaces were influenced by baroque style, as well as the artists Peter Paul Rubens and Gian Lorenzo Bernini (Sayre, 2007). c. Rococo: This type of art stemmed from baroque in the late 18th century in France due to the fact that baroque artists began to experiment giving up their symmetry and turned to creating ornate and playful art (Sayre, 2007). A lot of this art was created to be motifs of decoration and often criticized for its lack of sophistication. However, despite the controversies, it still remains a part of art history and so do the artists that incorporated it like Franz Anton Bustelli and Andrea Casali (Sayre, 2007). d. Neoclassicism: Unlike Rococo style’s seemingly unimportance, the neoclassicism era was distinct and memorable through its utilization of the visual arts like music, architecture, literature, and theatre and occurred late 19th century all over Europe (Sayre, 2007). It actually became a sort-of outspoken response to the â€Å"shallow† form of Rococo. It portrayed elements like war, politics and bravery (Sayre, 2007). Lastly, the artists that represent this period are Sir Christopher Wren and William Kent. e. Romanticism: This era is viewed as being the intellectual era, not romance, that gained popularity in the late 18th

Titration Lab Essay Example for Free

Titration Lab Essay Method for Control of Variables 1. In order to control the titration of potassium permanganate, we used the pipette to make the titration constant. We also used the same amount of chemical solutions, with the same flasks, to make the titration as constant as possible. 2. To control the amount of redox in the experiment, we have used the pipette to keep on putting the same amount of drop every time. The pipette made the amount of redox constant for every trial, and made the data more accurate. 3. In order to control the amount of potassium permanganate, we have measured the solution with the same plate and same scale. Since we have used the same materials, the amount used was very close. 4. To control the amount of force put in to mix the solution, I used my right hand for every trial and did not vary the length and procedure to mix. I have mixed the solution 5. In order to control the temperature of the liquids, I have used the same room at the same time. I did not used any air conditioning to change the temperature. Method For Data Collection 1. I have weighed out exactly 2.5 grams of AR ammonium iron (II) sulphate crystals, and dissolved them in approximately 40cmà ¯Ã‚ ¿Ã‚ ½ of sulphuric acid solution with a concentration of approximately 1 mol dm-à ¯Ã‚ ¿Ã‚ ½. 2. I did NOT heat the solution to assist the dissolving of the solution. 3. I made up to 100cmà ¯Ã‚ ¿Ã‚ ½ of the solution into a volumetric flask and mixed the solution. 4. I have used the pipette to pipette 10cmà ¯Ã‚ ¿Ã‚ ½ of the solution into a conical flask and added about an equal volume of distilled water. 5. I titrated this with 0.0200mol dm-à ¯Ã‚ ¿Ã‚ ½ potassium manganate (VII) solution to a faint pink color. 6. I repeated the titration for at least 2 times for accuracy in the data and recorded all the results. Table of Raw Results Table Showing Volume of KMnO4 Used to React With the Solution Initial Reading Final Reading Volume of KMnO4 The error or uncertainty of this data is à ¯Ã‚ ¿Ã‚ ½0.05cmà ¯Ã‚ ¿Ã‚ ½. However, the uncertainty for the volume difference is not à ¯Ã‚ ¿Ã‚ ½0.05cmà ¯Ã‚ ¿Ã‚ ½, but is à ¯Ã‚ ¿Ã‚ ½0.10cmà ¯Ã‚ ¿Ã‚ ½. This is because there are two à ¯Ã‚ ¿Ã‚ ½0.05cmà ¯Ã‚ ¿Ã‚ ½ datas, and if you add them up, you will get à ¯Ã‚ ¿Ã‚ ½0.10cmà ¯Ã‚ ¿Ã‚ ½. Evaluation Improvements: In this experiment, there were several inaccurate results and some mistakes I could have improved. 1. Pipette: For each drop from the pipette, there were same amounts of solutions, but since it is made by human hand, there should have been a slight difference in each drop. 2. Temperature: Although I have done this experiment in one class period, there were slight changes in the weather, causing the temperature to change. This could have affected the data results. 3. Force: The force applied to the solution and the flask was approximately the same, but there were some differences since it was done by humans. Humans never can do the same exact thing over, and so there should have been a slight error. Conclusion My hypothesis for this experiment was correct, because it took about 10 drops to titrate. Although there were some slight errors during the experiment, the experiment itself went fairly well, as there werent any big outstanding errors in the data and procedures. The main aim of this experiment, titration of redox with potassium permanganate, was well presented, and overall the experiment was good. Problem Calculation 1. MnO4- + 8H+ + 5Fe- = Mn2+ + 4H2O + Fe3+ 2. 5 moles of Fe2+ is required. 3. 10cm3 = 0.01dm3 0.02 mol dm-3 x 0.01 dm3 = 0.0002 mol 0.0002 moles of KMnO4 is present. 4. MnO4- : Fe2+ 1:5 0.0002 mol : 0.001 mol 0.001 moles of Fe2+ is present in 10cm3 of the solution. 5. 0.001 mol x 10 =0.01 mol 0.01 moles of Fe2+ is present in 100cm3 of the solution. 6. 1 mole of Fe2+ = 56grams 56g x 0.01 mol = 0.56g 0.56 grams of Fe2+ is in the ammonium iron (II) sulfate 7. Number of moles of ammonium iron (II) sulfate = 39 0.56g/(39mol x 0.1) = 14.4% 8. 1 mol of ammonium iron(II) sulfate = (NH4)2Fe(SO4)2 x 6H2O = 2N + 8H+ 1Fe+ 2S + 😠¯ + 12H + 6O = 392 grams 56g/392g = 14.3% 9. My result was 14.4% and it is almost equal to the correct value which is 14.3%. The difference is only 0.1%. 10. The iron (II) salt might evaporate if I heat it, and will affect the result.

Class and Culture in Urban American Essay -- Gangs Crimes Cultural Soc

Class and Culture in Urban American A gang is a loosely organized group of individual people who join forces for social reasons. Or anti-social reasons depending on how one looks at it. A person may join a gang for numerous reasons. These reasons include the need for â€Å"identity, discipline, recognition, love, money, and belonging.† 5 â€Å"Today there are approximately 274 Blood and Crip gangs in Los Angeles County alone.† 1 The gangs that are often in the news are usually made up of African-Americans. â€Å"African-Americans first formed street gangs in the late 1920s and early 1930s on the east side of Los Angeles near Central and Vernon Avenues. They were also forming in the downtown area of Los Angeles around the same time.† 4 Los Angeles is not the only area where gangs are visible, but it is often the area that will be associated with the topic of gang violence. â€Å"During the years to follow the early 1930s, African-Americans began to move south from downtown Los Angeles, down Central Ave towards Slauson Avenue.† 4 Whites primarily occupied this area during the 1920s, but African-Americans started moving in when the 1930s began. As the years went on and the time became closer to the present, these old gangs faded away, and new gangs surfaced. These new gangs were a more violent, dangerous type of group. Confrontations that would have led to fistfights in the 1930s progressed into fights that included chains, knives, and guns during the 1970s and 1980s. The two main names that will be associated with gang crime and activity these days are the Bloods and the Crips. These two names raise fear in most members of the community in the United States. The Bloods and the Crips are names that are synonymous with bloody ... ...ls, and parents to do their part. Together maybe we can put a halt to gang activity all together.

Formalism and Realism in the Movie Hero

Movie: Hero Director: Zhang Yimou Cast : Jet Li, Tony Leung Chiu Wai and Maggie Cheung Year of production: 2002 Country of production: China Language: Mandarin Film synopsis: The Qin King was obsessed with conquering all of China and becoming the first Emperor. He had been the target of assassins throughout the other states. Among them none inspired as much fear as the three legendary assassins, Broken Sword, Flying Snow and Sky. To anyone who defeated the three assassins, the King of Qin promised great power, mountains of gold and a private audience with the King himself. Following this Nameless came to the palace bearing the legendary weapons of the slain assassins, sitting in the palace, and told his extraordinary tale. Journal question: How does the colour cinematography of Hero (Zhang Yimou, 2002) contribute to formalism? â€Å"In art theory, formalism is the concept that a work’s artistic value is entirely determined by its form—the way it is made, its purely visual aspects, and its medium. Formalism emphasizes compositional elements such as color, line, shape and texture rather than realism, context, and content. . In Hero, Zhang Yimou combines cinematography with mise en scene to bring his own vision of the story, particularly with the use of certain colours. There are a total of five colours in this movie which choosed to express different versions or point of views ; black, white, red, blue, and green. Zhang Yimou uses the four colours, Red, Green, Blue and White, to tie in four different segments of the story. On the other han d, each of them also contains a different story The King of Qin’s palace is black, enlivened only by splashes of red. This forms the beginning and the end of the story and the overall feel of this sequence extends into the first fight between Nameless and Sky. The chosen colour metaphorically represents the battle between good and evil. Red dominates the first version of the story by Nameless in which he describes the calligraphy school, the attack by the Qin army, the stabbing of Broken Sword and the subsequent fight between Flying Snow and Moon. The color of red brings emotion, such as love, anger, passion nd romance. It portrays the tension between lovers and their passion for revenge to the King Qin. The costumes of the characters are in red, as well as the props. The red is a Kodak red as said by the film’s cinematographer. It's a much more saturated solid red. Blue becomes the colour for the second version of the story by the King himself. During the part of the story telled by the King, it evolved some fighting sequence in a lake. Since the colour of water is blue, so this section of story surrounded by blue colour with costumes and props and also location as well as the lake. Blue also represents peace, calmness and detachment. The colour suits the King as he shows peace in discovering Nameless true plan, which is to kill the King. The story version of the king surrounded with blue colour as well. Green is the colour for the story that Nameless doesn’t necessarily know since it covers the first meeting of Broken Sword and Flying Snow and also the failed assassination attempt. Since green colour known for memories and knowledge, it used to portray the flashback scene which evolve broken sword and flying snow. Broken Sword believes that the King of Qin has the power to unite these kingdoms for the greater good of the future. White is the final colour, dominating the deaths of Flying Snow and Broken Sword and alternating with the black sequences back in the palace. this scene is achieved through mise en scene, cinematography and post-production. The characters wear white and the props are in white colour. The lighting is over exposed to highlight the white colour . The scene reflects truth of the characters’ intentions. Reading synopsis: The Language of Film Mise en scene, cinematography, editing and sound can be combined to form a language that is used to tell stories and express meanings.

Yeast Fermentation

The purpose of this experiment was to observe the process in which cells must partake in a respiration process called anaerobic fermentation and as the name suggests, oxygen is not required. This particular procedure, which Is catabolic meaning, it breaks down energy, can be present In to types of fermentation; alcohol In yeast or lactic acid in muscles. This Is a continued reaction from glycoside, where glucose Is broken down Into three carbon sugars.The products of alcohol fermentation are ethanol and carbon dioxide and the products produced by lactic acid fermentation is lactate. As we observed the effects of yeast fermentation, It Is Imperative to know that yeast makes energy through fermentation. Yeast fermentation was combined with several different saccharine such as glucose, sucrose, starch, and fructose. Dolled water was also included In this experiment as another variable. The control was simply a vial of yeast and distilled water at room temperature.Each vial was filled co mpletely with the mixture (the solution was composed of individual saccharine and water) and then the gap was measure in 2 minute increments. The spectrometer was set at a 600 mm absorbency and each vial was measure, once again, in every two minute intervals. The purpose of this experiment was to better understand the logistics behind the fermentation process. In tube one, the succinctness was fumigated. The second tube differed in the fact that there was boiled water, which is not a suitable living indention for yeast, and therefore the enzyme was denatured.There was no carbon dioxide produced when mixed with boiled water but without that variable's presence, there was a greater amount of carbon emission. Tube three had an added inhibitor so therefore the rate of reaction was considered slow which can be observed in figure 1-1 . Adding the inhibitor meant that the enzyme was occupied and not in absorbency. Tube four, the final tube, had the most substrate included and due to this, the enzyme had a chance to bind to an activation site despite the inhibitor.
