Jenny Holzers Untitled | Analysis
Jenny Holzers Untitled | Analysis Erin Brubaker Fig. 1. Jenny Holzer, Untitled. 1989,16 x 162 x 6 Solomon R. Guggenheim Museum, New York.Ã Untitled is a piece of art by Jenny Holzer that was located in the main lobby of the Solomon R. Guggenheim museum in 1989. Selections of phrases are presented in LED lights that follow the spiral ramp, drawing the eye gradually upwards. Constantly moving and changing, the sentences are presented in a variety of colors and fonts in all capital letters. On the floor below are marble benches arranged in a circle which have additional phrases etched into them. From every angle, the viewer is given a new statement to read. The phrases Holzer included make stances about several areas of interest, for example political, social, and personal. In figure 1, the top level of electronic text reads PRIVATE PROPERTY CREATED CRIME. This sentence exemplifies her style of writing, which involves making bold claims that are a matter of opinion. Holzers writings, as well as the materials she uses to present them, are designed to make the viewer react strongly, causing them to call into question what is presented to them as truth on a daily basis. Holzer uses her materials to make a comparison to the media. By using LED lights as her method of expressing her writing, Holzer shows that her message is for the public. LEDs are familiar to most people because we see them in everyday life. In cities they are used to display the names of hotels, restaurants, casinos, and other businesses. They can also be found on buildings to inform breaking news, or advertise products. Viewers can react to her phrases similarly to the way they would react to a headline news story. Underneath the LEDs are seventeen marble benches with her texts etched on the tops and sides of them. The benches contrast the LED boards because instead constantly changing; they are static and have a sense of permanence. While the physical structures Holzer uses are important, the messages written on them are what Holzer uses to provoke further thought. The content of Holzers work is significant because it provokes thought. Her piece in the Guggenheim included texts from several of her past collections of writings. The collections she chose from were Truisms, Inflammatory Essays, The Living Series, The Survival Series, Under a Rock, and Laments. Truisms, which she wrote in the late 1970s, is a body of one-liners, slogans, and aphorisms. The stances they take are difficult to categorize because it seems like they come from a variety of perspectives. The intentions of the Truisms are not clear, but they all act to surprise the reader. For example, MONEY CREATES TASTE and AN ELITE IS INEVITABLE are thought provoking, but do not demand action from the reader. This aspect of her work will change in later writings. Holzers next body of writing was called Inflammatory Essays. In this series, her phrases were more forceful and assertive than Truisms. The essays are aggressive from beginning to end, and are sequences of private thought. At times her statements contradict each other, for example the beginning of one of her essays reads DONT TALK DOWN TO ME. DONT BE POLITE TO ME. According to Terry Barrett, The essays show how language, truth, force, and power can pervert each other (Barrett 1994, 60). In other words, this way of writing serves to confuse the reader, and possibly make them question what is presented to them as truth. The difference between Truisms and her later collections Living and Survival is that the intentions of her work become clearer. Although the texts in these series do not have a unifying purpose, many of them act to advertise, instruct, or cause emotional reactions. Several phrases in Survival provoke fear and uncertainty. For instance, THE BEGINNING OF THE WAR WILL BE SECRET, and YOU ARE TRAPPED ON THIS EARTH SO YOU WILL EXPLODE suggest that the future will be dangerous. Under a rock is written from the perspective of someone who has experienced or witnessed dark crimes, such as murder and terrorism. The collection is made up of gory and disturbing descriptions that involve pain. This is a similar theme to her other collection, Laments. Laments is Holzers most political collection of phrases. For this series, she uses her imagination to create voices for innocent lives lost in the AIDS epidemic happening at the time. According to Paula Geyh, In Laments, Holzer sought to give voice to the final thoughts of the dead, to give them a chance to say what they couldnt say(Geyh 2002, 178). It is significant that this is her first series in which she uses the pronoun I. Instead of writing from an outsiders perspective, this series is much more based on an individual. She used her anger about the death toll of the disease to make a political statement that there was no good reason for that many people to die. Untitled at the Guggenheim was a display of language that publicized Holzers private thought. She demonstrates a variety of perspectives in her writing that details the human condition. Her materials she used to present her writing gave her work a sense of importance to the public. The exhibit was designed to provoke thought and emotions. The unifying theme in all of the texts that are a part of Holzers exhibit is that they impose reactions on the viewer, making them rethink what they believe to be truth.

Liberty Bell Essays -- essays research papers
Among the more obscure events in American history involves the Liberty Bell's travels by rail car around the United States to be placed on exhibit at numerous World's Fairs. From 1885 to 1915, the Liberty Bell traveled by rail on seven separate trips to eight different World's Fair exhibitions visiting nearly 400 cities and towns on those trips coast to coast. At the time, the Liberty Bell's trips were widely publicized so that each town where the Liberty Bell train stopped was well prepared for their venerable guest. Each stop on the way to the host World's Fair exhibition lasted anywhere from a few minutes to a couple of hours. The Liberty Bell was nearly always met with military salutes, parades, patriotic music and throngs of cheering men, women and children. In 1873, Philadelphian Henry Seybert donated to the City of Philadelphia a new bell and a large clock for tower of Independence Hall. Seybert commissioned the Meneely and Kimberly Bell Foundry to cast the bell and have it installed in the steeple by July 4, 1876 in time to usher in the Centennial anniversary celebration. The bell was cast using a mixture of 80% copper and 20% tin with the addition of one hundred pounds each of four cannons - a British and American cannon from the battle of Saratoga and a Union and Confederate cannon from the battle of Gettysburg. The bell weighs 13,000 pounds representing 1,000 pounds for each of the 13 original states and bears the following inscriptions: Around the crown: "Glory to God in the highest and on earth peace, good will toward men - Luke, chapter II, verse 14." Around the lip: " Proclaim liberty throughout all the land unto all the inhabitants thereof - Leviticus, chapter XXV, verse 10." Upon one side of the of the bell is cast - "Presented to the city of Philadelphia, July 4, 1876, for the belfry of Independence Hall, by a citizen." On the opposite side is the date "1776" and the coat of arms of the United States set in a shield containing 13 stars. I... ...;. Unfortunately, the fair was not a tremendous success due to low attendance - only 10 million of the expected 50 million visitors attended. Attributing to low attendance was the rain that was present on more than half the days the fair was open. While the Liberty Bell remained in its home in Independence Hall not far from the fairgrounds its image was used repeatedly as a symbol of the Exposition. The Liberty Bell had long since come to represent liberty and freedom for the United States and using its image on Exposition souvenirs was ideal in light of the fair's theme - our nation's 150th birthday. In 1950, the United States Department of the Treasury assisted by several private companies selected a foundry in Annecy-le-Vieux, France to cast 55 full-sized replicas of the Liberty Bell. The bells were shipped as gifts to states and territories of the United States and the District of Columbia to be displayed and rung on patriotic occasions. This was part of a savings bond drive held from May 15 to July 4, 1950 with the slogan "Save for Your Independence."

Heavenly Creatures Film Analysis Essay
Heavenly Creatures is based on a true story about two teenage girls who murder one of their mothers in Christchurch, New Zealand. The film, directed by Sir Peter Jackson, uses many techniques in the opening scene to efficiently show how vital this scene is to the film. These techniques include a documentary clip, costume, cinematography and sound. In the beginning of the opening scene, a documentary clip is used to introduce us to the town of Christchurch, New Zealand. The director uses this to show us how seemingly perfect the town of Christchurch was. In the clip it includes appealing imagery of flowers, gardens, lakes and schools. Accompanied with joyful music, Christchurch is presented to be the idyllic town. Described as a ââ¬Å"quiet haven,â⬠the audience become aware of how unlikely and implausible it would have been at the time for two teenage girls to commit a brutal murder against one of their mothers. The clip is used to create juxtaposition and shock the audience and to illustrate how alarming it would have been in the 1950ââ¬â¢s for a murder of this nature to have occurred. Jackson wanted us to see the situation through the eyes of the people of Christchurch in the 1950ââ¬â¢s ââ¬â it would have been completely out of character for their town, causing quite a scandal. Therefore the media, at the time, would have had a field day. The media were quick to accuse the girls of being ââ¬Å"lesbian school girl killers,â⬠the girls became far more outcast than they already were. They were essentially the villains of the town. Jackson said up until the murder, he had tried to portray the girls from a sympathetic point of view. They were misunderstood creatures, exiled from their peers. The cinematography is used very effectively in the opening scene of ââ¬Å"Heavenly Creatures.â⬠An example of cinematography in the scene is when we see shots of the girlsââ¬â¢ legs running up a path. They are covered in blood and screaming. This is paralleled with another shot of the girlsââ¬â¢ legs, but this time they are running towards Julietââ¬â¢s parents, on a boat. The next shot shows the girls both yelling ââ¬Å"Mummyâ⬠as they get closer to Julietââ¬â¢s mother. These shots show the girls are running from reality to fantasy. The fantasy scene where they are running towards Julietââ¬â¢s mother shows that the girls desired to be sisters. Pauline would have done anything to be a part of the Hulme family, including killing her own mother. Theà director wanted the audience to see how much of an intense relationship Juliet Hulme and Pauline Parker had- they killed someone in an attempt to stay together. The black and white colouring on the boat scene represents the girlsââ¬â¢ fantasy, and how it was not real. The director also uses establishing shots to introduce us to the two main characters. We see Pauline exit from a shed-like house and jump down from over a fence. Her hair is unkempt, and she seems to be unhappy. Later in the scene when Pauline has arrived at school, there is a tracking shot of her walking down a school corridor. She seems awkward, and as she walks past her school peers she seems outcast. When people greet her, she would half-heartedly reply. The director wants us to see that Pauline does not come from a rich family, and to show she is quite different than the rest of her peers. Juliet, however, is first introduced with a shot of her travelling in a flash car, and later an establishing shot of her with her perfectly tidy hair and uniform as she is being introduced to the French class. The director shows that she comes from a wealthy and respectable background. When Juliet outsmarts the French teacher and is not afraid to speak up for herself, the audience is shown that Juliet, as well as Pauline, stands out from the rest of the class. The girls together were outsiders, and became fast friends because of this. Costume is also used skilfully in ââ¬Å"Heavenly Creatures.â⬠In the majority of the opening scene we see the girls, Pauline and Juliet, dressed in their identical school uniforms. As the school gathers for their morning assembly, they sing school hymns. High angle shots show all the girls in their identical uniforms and haircuts. The director wants us to realise that in a girlââ¬â¢s school in the 1950s, individuality was not widely accepted. The girls were expected to be well behaved, polite and obliging. Every girl is the scene is singing and looking relatively happy ââ¬â except for Pauline. Though she is dressed correctly from top to toe in he r black leather shoes and white socks, her blue school-girl uniform dress and her short hair, Pauline stands out from the crowd. She is not singing the hymn and looks bored and sullen. Her hair is also far more dark and unruly than the rest of the girls around her. The director wants to show that Pauline is not just the average school girl, and she detests being in unison with everyone else, as she desires to be unique. Pauline and Juliet both had the desire to be unique, to stand out from the crowd with their own ideas andà own opinions, but that was not socially acceptable in their society or school. People, including the girlsââ¬â¢ own family looked down on them for creating their fantasies and imaginary worlds. They did not fit in with their society in the 1950s. Expertly crafted in the ââ¬Å"Heavenly Creaturesâ⬠opening scene is the soundtrack. During the documentary clip, the music playing is cheerful and happy. This is because the clip is showing Christchurch to be a beautiful and harmonious place. The music helps to create the illusion that everything in the world of Christchurch is perfect. But as the scene transitions from the documentary clip to the actual story line, the music becomes dark and almost menacing. The director uses this to show that Christchurch is hiding a daunting side to it; this side involves deluded and murderous young girls. The music also creates tension which could be linked to how the outside world of Christchurch at the time were feeling ââ¬â the shock of the murder case was startling, and the audience lives this too, through use of music. The director also wants to see past what Christchurch looks like on the outside, and realise that underneath, the town has damaged and scared parts, just as every other town does. The town of Christchurch has both good and bad people who do good and bad things. The harmonious music and the dark music is a way of symbolising the town and the people who live in it.

Essay on Thomas Jefferson A Controversial Man - 1785 Words
Most people only know Thomas Jefferson as the third President of the United States but he was much more than that. Thomas Jefferson was a very controversial man. From his work as a Founding Father to the mysteries of his personal life, Americans continue to find him to be very intriguing. He challenged the way the government was run previously by the first two presidents and became an advocate for the people. This paper talks about Jeffersonââ¬â¢s role as a leader during the creation of the Declaration of Independence, his life before he became well-known, and the controversies related to his relationship with his slave named Sally Hemings.

Fireflies, Family Lampyridae
Who hasnââ¬â¢t chased a blinking firefly on a warm summer night? As children, we captured their luminescence in glass jars to make insect lanterns. Unfortunately, these beacons of childhood seem to be disappearing due to habitat loss and the interference of manmade lights. Fireflies, or lightning bugs as some call them, belong to the family Lampyridae. Description: Fireflies are usually black or brown, with elongate bodies. If you handle one, youll notice they feel somewhat soft, unlike many other kinds of beetles. Hold it gently, as its quite easy to squish. When viewed from above, the Lampyrids seem to conceal their heads with a large shield. This feature, an extended pronotum, characterizes the firefly family. If you examine the underside of a firefly, you should find the first abdominal segment is complete (undivided by the hind legs, unlike in ground beetles). In most, but not all fireflies, the last two or three abdominal segments look quite different from the others. These segments are modified as light-producing organs. Firefly larvae live in moist, dark places ââ¬â in the soil, under tree bark, and even in swampy areas. Like their adult counterparts, larvae glow. In fact, fireflies produce light in all stages of their life cycles. Classification: Kingdom ââ¬â AnimaliaPhylum - ArthropodaClass ââ¬â InsectaOrder ââ¬â ColeopteraFamily ââ¬â Lampyridae Diet: Most adult fireflies do not feed at all. Firefly larvae live in the soil, preying on snails, grubs, cutworms, and other soil-dwellers. They inject their prey with digestive enzymes that paralyze and break down the bodies, and then consume the liquefied remains. Some fireflies eat mites or even pollen. Life Cycle: Fireflies typically lay their eggs in damp soil. Eggs hatch within weeks, and larvae overwinter. Fireflies may remain in the larval stage for several years before pupating in the spring. In ten days to a few weeks, adults emerge from the pupal cases. Adults live just long enough to reproduce. Special Adaptations and Defenses: Fireflies are best known for their coolest adaptation ââ¬â they produce light. Male fireflies flash their abdomens in species-specific patterns, hoping to attract the attention of a female hiding in the grass. An interested female will return the pattern, helping guide the male to her in the darkness. Some females use this behavior for more sinister means. A female of one species will purposefully mimic the flash patterns of another species, luring a male of another kind to her. When he arrives, she eats him. Male fireflies are rich with defensive chemicals, which she consumes and uses to protect her eggs. Most females dont practice cannibalism, though. In fact, since females live just a few days spent waiting in the grass for a mate, some dont even bother to develop wings. Firefly females may look just like larvae, but with compound eyes. Many fireflies use foul-tasting defensive compounds to deter predators, like jumping spiders or even birds. These steroids, called lucibufagins, cause the predator to vomit, an experience it wont soon forget when it next encounters a firefly. Range and Distribution: Fireflies live in both temperate and tropical climates throughout the world. About 2,000 species of Lampyrids are known globally.

Alice Walker s Everyday Use - 1924 Words
Family, is a word that is familiar to everyone, but may have different meanings for each individual. It is most commonly seen as a group consisting of parents and children. Family can be defined not just through blood but through love and commitment as well. In our readings this semester, one of the frequent themes has been about family. The unconditional love found in a family does not prevent them from experiencing difficult dilemmas. Families can have powerful influences on an individual being either positive, negative, or even both. The influences brought on by families can give a sense to someone as more of a positive feeling such as, attachment, love, and thrill, or a sense more negative such as pain, anger, and guilt, or, can evenâ⬠¦show more contentâ⬠¦In Theodore Roethkeââ¬â¢s poem, ââ¬Å"My Papas Waltzâ⬠, the dance between the father and son can be viewed from a loving perspective or a fearful one.

Aviation Benchmarks Essay Research Paper Aviation BenchmarksThousands free essay sample
Aviation Benchmarks Essay, Research Paper Aviation Benchmarks Thousands of people have contributed to Aviation. Dreams by the Wright Bothers made flight possible for all of us. Others like Emelia Earhardt, and Charles Linburg stretched the bounds to carry through what had neer been done earlier. Many have even given their life to be in the air. I will discourse some of the paramount events and people that helped exceed Aviation. The most appropriate topographic point to get down is on the Seventeenth of December in 1903, the brothers Orville and Wilber Wright flew the first powered aircraft a sum of 120 pess in 12 seconds. Wilber the eldest, and younger brother Orville ever were fascinated by flight. During their childhood, sailplanes and balloons were being used. Painstaking attempts were made by them subsequently in life to make an expeditiously powered trade. They had used aeromechanicss tabular arraies set Forth by Langley to prove their ain sailplanes. We will write a custom essay sample on Aviation Benchmarks Essay Research Paper Aviation BenchmarksThousands or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page They found that the tabular arraies didn # 8217 ; t supply adequate lift to acquire barely anything off the land. So they set out to hammer their ain tabular arraies by expereimenting with two-hundred different flying designs in a home-made air current tunnel. They invalidated Langley # 8217 ; s aeromechanicss tabular arraies. From there with the aid of mechanic Charles Taylor, they were able to plan an engine visible radiation and yet powerful plenty to propell a little trade. The powerplant on the # 8220 ; Flyer 1 # 8243 ; weighed 170 pound. and operated with 12hp at 1200rpm. With this design they made air power history as described above. Subsequently on that twenty-four hours though, Wilber soloed a flight of 152 pess in 59 seconds. After 100s of successful flights and small attending, the military took an involvement in their advancement. They designed the first plane that could turn, bank, and do calculate 8s for one-half an hr. They named thier creative activity the Flyer III. The Wright # 8217 ; s winging machine recieved a patent on March 22nd, 1906. One twelvemonth after that in 1907, the foundation of the Aeronautical Experimental Association ( FEA, now the FAA ) was founded. I feel its lone proper to honour the persons that tested themselves and thier trade in order to learn us about aircraft design, processs, and human bounds in the air. The first individual to decease in an aeroplane clang was Lt. Thomas E. Selfridge. He was winging with Orville in 1908. No admiration Orville was the 4th individual in history to acquire a pilot certification: the 3rd was Lousis Paulhan, 2nd was Frank Lham, and the first was Glen Curtiss. The first pilot to be killed was Eug ne Lef bvre in France, on Sept 7, 1909. Calbreth Perry Rodgers bought the first Wright aeroplane. Rodgers recieved 90 proceedingss of flight direction from Wilber. After his ample flight school, Rodgers accepted the challeng of winging across the United States for a award of $ 50,000 ( if he could make it in 30 yearss ) offered by a publishing house. He got a soft drink shaper to sponser him, and therefore the flight of Vin Fiz ( name of the sodium carbonate ) got off the land. He started in New York, and shortly ran into a batch of problem. He crashed someplace between 20 and 36 times. His patron fixed him up though. It took the persistant and invariably bandaged Rodgers 49 yearss to acquire to Pasadena ; funny merely 82 hours and 4 proceedingss were spent in the air. Luckly Rodger # 8217 ; s 51mph clangs didn # 8217 ; t kill him. Amelia Aerhart is another noteworthy individual that sacrificed herself for the promotion of air transit. She was the first adult female to traverse the Atlantic-from Newfoundland to North Ireland, 2,026 stat mis. She did it in 1932. But this wasn # 8217 ; t adequate. In 1937 she wanted to circle the Earth at the equator. Unfortunately she missed the bantam Howeland Island in the Pacific and was neer seen once more. Other indispensable people in air power include Glen Curtiss, Charles Lindbergh, and Ilray Jeppeson. Glen Curtiss flew from Albany to New York in 1910, which crushed the old distance record of 24 stat mis. His flight amounted to 143 entire stat mis. Curtiss was besides a innovator in early engines. Charles Lindbergh is credited for the first flight across the Atlantic from New York to Paris. His flight on the 20th of May, 1927 took him an astonishing 33 hours and 20 proceedingss. His plane # 8220 ; The Spirit of Saint Louis # 8221 ; traveled 3,610 stat mis. Lindbergh thrilled everyone in the provinces and positive people that aeroplanes were # 8217 ; nt merely for barnstormin g shows. They could be used for the transit of mail, lading, and even people. This was all a reasonably new construct. Ilray Jeppeson was a innovator in the country of flight pilotage. In the 1920ââ¬â¢s he was an air mail pilot who methodicly charted and mapped mention points and jeopardies. Soon his fellow employees wanted transcripts, and the concern was born. Later he provided pilotage charts and maps to about every major airdrome in the universe. Finally, I will advert a critical flight made by Louis Bleriot across the English Channel. Bleriot was a mechanical fiddler. Kind of like Bellââ¬â¢s male parent in Beauty and the Beast. Bleriot was in the headlamp concern but sought to construct an aeroplane. He accomplished this when he engineered the Model XI monoplane in 1909. With predictable drop the balling manner, he finished the 22 stat mi stretch across the channel by crashing his overheated trade near Dover Castle. He captured the imaginativenesss of all who heard about i t. I did program on traveling into great item about the developments in air foils and aeromechanicss. But I # 8217 ; ve decided its merely excessively complicated. I will travel over some cardinal improvemnets on aerofoils through the old ages. We all understand the construct of Bernouli # 8217 ; s Principle whre the air going over the top of the foil will be accellerated because its somewhat longer, and therefore force per unit area is decreased. The unchanged speed of the air going beneath the foil consists of a higher force per unit area that pushes the air foil up. This construct International Relations and Security Network # 8217 ; t wholly true. Research indicates that air that is seperated doesn # 8217 ; t meet at the draging border simotaneously like one time thought. So, basicly we truly wear # 8217 ; t cognize how it works, we merely discovered the aerofoil through test and mistake. And from there we tweaked it to acquire the coveted consequence. Newton helped us to see t he four forces moving on an aeroplane in flight: lift, push, weight, and retarding force. Therefore we have done much research refering how to diminish retarding force. In WWII the Germans came up with the swept wing design. So alternatively of the organic structure and wings coming together at near perpendicular angles, they are swept back like in the form of an pointer. This reduces, or more accurately delays retarding force. Thus higher velocities can be obtained. Last, another of import devolopment in earodynamics is the laminal air foil. A regular air foil will hold Eddies of air resiling off the surface of the wing. But a laminal air foil will maintain the air flow smooth over the top of the wing and hence a decrease in retarding force is accomplished. Now, I can depict a few of the countless alterations aviation powerplants have gone through. The male parent of aircraft engines is known as Glen Curtiss. He began by doing two cylinder engines for bikes, and in 1906 was looking to sell his engines for aircraft. From what I # 8217 ; ve read he wasn # 8217 ; t a savvy salesman. Once he put his engine in the # 8220 ; June Bug # 8221 ; and flew an amazing 1 kilometre, subsequently he worked with the Navy in planing sea planes. Some clip after the Curtis the Conquerer engines, the Clerget came into usage. It had 1200hp. In 1937, Daimler-Benz came out with their DB-601. It had twelve cylinders, was liquid cooled, and produced 1,475hp. During this epoch, Pratt and Whitney, Lycoming, and Wright Aeronautical wholly contributed to the advancemnet of the recipricating and radial engines. In the early 1940 # 8217 ; s the industry came out with fanjets, propjets, and the fanjet engine designs. Turbofans were of import to the industry, so we re coal-black engines. These two types of engines made ace sonic flight possible, and non to advert a fast, efficient, and safe manner to go. There are excessively many people and developments that contributed to aviation as we know it today. I tried in vain to capture the most of import events in the industry since it # 8217 ; s birth 97 old ages ago. Im certain I missed much. Aviation has become a portion of everyone # 8217 ; s lives. We depend on it for commercialism and enjoyment. The industry will go on to thrive, and better.
