Apollo 4 - NASAs First All Up Test

Apollo 4 - NASA's First All Up Test On January 27, 1967, tragedy struck on the launch pad during a preflight test for Apollo 1 (also called AS-204), which was scheduled to be the first Apollo manned mission, and would have been launched on February 21, 1967. Astronauts Virgil Grissom, Edward White, and Roger Chaffee lost their lives when a fire swept through the Command Module (CM). The accident was the first major mishap in NASAs short history, and it shocked the nation.   Moving Beyond Tragedy NASA made an exhaustive investigation of the fire (as it does with all space mishaps), which resulted in extensive reworking of the CMs. The agency postponed manned launches until officials cleared the new capsule design for use by human crews. In addition, Saturn 1B schedules were suspended for nearly a year, and the launch vehicle that finally bore the designation AS-204 carried a Lunar Module (LM) as the payload, not the Apollo CM. The missions of AS-201 and AS-202 with Apollo spacecraft aboard had been unofficially known as Apollo 1 and Apollo 2 missions (AS-203 carried only the aerodynamic nose cone). In the spring of 1967, NASAs Associate Administrator for Manned Space Flight, Dr. George E. Mueller, announced that the mission originally scheduled for Grissom, White and Chaffee would be known as Apollo 1, as a way to honor the three astronauts. The first Saturn V launch, scheduled for November 1967, would be known as Apollo 4. No missions or flights were ever designated as Apoll o 2 and Apollo 3.    The delays caused by the fire were bad enough, but NASA also faced budgetary cutbacks as it raced to reach the Moon before the end of the decade. Since the U.S. was in a race to get to the Moon before the Soviets could get there, NASA had no choice to but move ahead with the assets it had. The agency did further tests on the rockets, and eventually scheduled the Apollo 4 mission for an unmanned flight.  It was referred to as  all-up testing. Resuming Space Flight After the complete retooling of the capsule, the mission planners for Apollo 4 had four major goals: Demonstrate structural and thermal integrity and compatibility of launch vehicle and spacecraft; confirm launch loads and dynamic characteristics.Verify operation of command module heatshield (adequacy of Block II design for reentry at lunar return conditions), service propulsion system (SPS; including no ullage start), and selective subsystems.Evaluate performance of emergency detection system in open-loop configuration.Demonstrate mission support facilities and operations needed for launch, mission conduct, and CM recovery. After extensive testing, re-resting, and training,  Apollo 4 launched successfully on November 9, 1967 at 07:00:01 a.m. EST from Launch Complex 39-A at  Cape Canaveral FL. There were no delays in the preflight preparations and with the weather cooperating, there were no delays during countdown. During the third orbit and after SPS engine burn, the spacecraft coasted to a simulated translunar trajectory, reaching an altitude of 18,079 kilometers. The launch marked the initial flight testing of the S-IC and S-II stages. The first stage, S-IC, performed accurately with the center F-1 engine cutting off at 135.5 seconds and the outboard engines cutting off at LOX (liquid oxygen) depletion at 150.8 seconds when the vehicle was traveling at 9660 km/h at an altitude of 61.6 km. Stage separation occurred only 1.2 seconds off the predicted time. Cutoff of the S-II occurred at 519.8 seconds. It was a triumphant, if subdued return to space flight, and moved NASAs goals to reach the Moon farther forward. The spacecraft performance went well, and on the ground, people heaved a huge sigh of relief.   A Pacific Ocean landing occurred on November 9, 1967, 03:37 p.m. EST, just eight hours and thirty-seven minutes and fifty-nine seconds after takeoff. The Apollo 4 Spacecraft 017 splashed down, missing its planned impact point by only 16 kilometers. The Apollo 4 mission was a success, all  objectives were achieved. With the success of this first all up test, the Apollo program resumed manned missions and moving toward the eventual 1969 target for the first human landing on the Moon during the  Apollo 11 mission.  After the loss of the Apollo 1 crew, the Apollo 4 mission benefitted from many tough (and tragic) lessons learned.

Tokugawa period until 1868 Research Paper Example | Topics and Well Written Essays - 2500 words

Tokugawa period until 1868 - Research Paper Example In fact, there had been no hiatus between high class and lower class cultures (Ng). Further I Ching scholarship which had achieved its highest status during the Tokugawa period and its aspects of yin-yang wu-hsing had also impacted on Tokugawa’s cultural aspects. The flower arrangement popularly known as Kado or Ikebana traceable to pre-Tokugawa period namely Kamakura period (1186-1336) had developed as a Buddhist art. It had been associated with nemustu (chanting to Amida Buddha) and renga (linked poetry) during the Muromachi period (1392 -1573). It came closer to chanoyu during the sixteenth century. The flower arrangement had been the most popular during the Tokugawa period. The yin-yang wu-hsing principle representing harmony of the universe was depicted in the flower arrangement relating to I Ching concepts of yin-yang, san-ts’ai associated with the three powers of heaven, earth, and man, and wu-hsing. The flower arrangement with three divisions was symbolic of hea ven, earth and man (Ng). Thus, the religions were the roots of Japanese culture and Tokugawa was no exception. Now the broad aspects of Tokugawa’s culture having been briefly examined, this paper will narrow down its research of Japanese Tokugawa’s culture to Theatrical forms (Kabuki) in the following pages. Kabuki Kabuki is depicted by the three Japanese characteristics referring to ‘dance, music and craft or skill’ as depicted below. Figure 1. (Source: creative-arts.net). Originally Kabuki was associated with â€Å"tilted† or â€Å"out of balance† characters depicted as ‘exotic’, racy, or debauched’. Though its origin comes from temple dance, Kabuki’s earlier recorded history shows much of its association with... The period between the ascendancy and the fall was the period of isolation of Japan from the rest of the world. The 268 years under the spell of Tokugawa clan had been characterized as ‘static political, social and cultural life’. Family structure, political structure and social class structure along with many values and ideas remained constant during the 268 years of Tokugawa rule. During this period, Buddhism and Confucianism had been rejected. The native religion Shinto re-emerged. The culture of Tokugawa period is indeed overwhelming with the Kabuki players surviving the period of seclusion and rigors of Tokugawa’s clans over more than two and a half centuries. The seemingly vulgar culture alleged to have been portrayed by Kabuki plays actually had been well intended as revealed in the above account of Nishiyama and Groemer. Otherwise, they would not have survived. The popularity of Kabuki amongst the lower classes had its own repercussions. The crowds gathering at the performance places often used to turn boisterous that Shougun had to ban the actors and dancers from towns and permitted them to perform only at the remote places close â€Å" pleasure quarters† in 1608. Kabuki’s early history shows that there had been links between such places of entertainment and theater as a source of entertainment at the places of pleasure for the common man popularly known as ukiyo (floating world). The actors of Kabuki Theater were social outcasts and theater managers were kawara kijiki (riverbed beggars) until 19th century when the actors were accorded the status of artists.

Speciation Essay Example | Topics and Well Written Essays - 250 words

Speciation - Essay Example These two processes  led to  the behavioural speciation between Sciuirus apbios and Sciuirus vulgaris. Allopatric speciation was a consequence of the geographic isolation of the Caribbean Sea. Initially, St. Kitts and Nevis were a single island and there only existed one squirrel species. However, there was the divergence of the initial island, and there emerged two small islands that contained different species of the first squirrel species. The diagram below best describes allopatric speciation: The bottleneck effect occurs when excessive tourism and development creates a genetic drift between animals of the same species. In this case, there was a volcanic eruption in St. Kitts that killed an enormous population of the squirrel population. The explosion led to massive loss of alleles in the genetic pool of St. Kitts rodents. Consequently, Sciuirus apbios evolved differently from Sciuirus vulgaris. The image below best describes the bottleneck effect: †¢ Sciuirus vulgaris has an average gestation period of 29.3 days compared to Sciuirus apbios that have a gestation period of 42.7 days. The difference in the gestation periods of the two species is significant enough to prevent successful reproduction. In conclusion, the emergence of Sciuirus apbios is a result of the divergence of the Sciuirus vulgaris population as a result of allopatric speciation and the bottleneck effect (Wolff & Sherman,

Problems Of The Aging Health And Social Care Essay

Problems Of The Aging Health And Social Care Essay for death from cancer, Management of the elderly cancer patient becomes complex because other chronic conditions, such as osteoarthritis, diabetes, chronic obstructive pulmonary disease (COPD), and heart disease, must also be considered in their care. The attitude of health care providers towards older adults affect their health care. Unfortunately, research indicates that health care professionals are significantly more negative in their attitudes towards older patients than younger ones. This attitude must change if the health care provider is to have a positive interaction with the elderly patient. These attitude appear to be related to the pervasive stereotyping of the elderly, which serves to justify avoiding care and contact with them, as well as being reminders of our own mortality. Ageism is a term used to describe the stereotyping of and discrimination against elderly persons and is considered to be similar to that of the racism and sexism. It emphasized that frequently the elderly are perceived to be repulsive and that a distaste for the aging process itself exists. Ageism suggests that he majority of elderly are senile, miserable most of the time, and dependent rather than independent individuals. The media have also influenced on going stereotypical notions about the elderly. Health care providers must learn to appreciate the positive aspects of aging so that they can assists the elderly in having a positive experience with their imaging procedure. PHYSICAL, COGNITIVE, AND PSYCHOSOCIAL EFFECTS OF AGING The human body undergoes a multiplicity of physiologic change second by second. Little considerations is given regarding these changes unless they are brought on by sudden physical, psychological, or cognitive events. Radiographers must remember that each elderly person they encounter is a unique individual with distinct characteristics. These individual have experienced a life filled with memories and accomplishment. Young or old, the definition of quality of life is an individual and personal one. Research has shown that health status is an excellent predictor of happiness. Greater social contact, health satisfaction, low vulnerable personality traits, fewer stressful life events have been linked to successful aging. Self-efficacy can be defined as the level of control one has over ones future. Many elderly people feel they have no control over medical emergencies and fixed incomes. Many have fewer choices about their personal living arrangements. These environmental factors can lead to depression and decreased self-efficacy. An increase in illness will usually parallel a decrease in self-efficacy. The elderly may experience changing roles from life of independence. The family role of an adult caring for children and grandchildren may evolved into the children caring for their caring aging parents. It is also a time of loss. Losses may include the death of a spouse and friends, as well as loss of income due to retirement. The loss of health may be the reason for the health care visit. The overall loss control may lead to isolation and depression in the elderly. Death and dying is also an imminent fact of life. The aging process alone does not likely alter the essential core of human being. Physical illness is not aging, and age-related changes in the body are often modest in magnitude. As one ages, the tendencies to prefer slower-paced activities, take longer to learn new tasks, become more forgetful, and lose portions of sensory processing skills increase slowly but perceptibly. Health care professionals need to be reminded that aging and disease are not synonymous. The more closely a function is tied to physical capabilities, the more likely it is to decline with age, whereas the closer a function depends on experience, the more likely it will increase with age. Joint stiffness, weight gain, fatigue and loss of bone mass can be slowed through proper nutritional interventions and low-impact exercise. The importance of exercise cannot be overstated . Exercise has been shown increase aerobic capacity and mental speed. Exercise programs designed for the elderly should emphasized increased strength, flexibility, and endurance. One of the best predictors of good health in later years is the number and extent of healthy lifestyles that were established in earlier life. The elderly person may shown decreases in attention skills during complex tasks. Balance , coordination, strength and reaction time all decrease with age. Falls associated with balance problems are common in the elderly population, resulting in a need to concentrate on walking. Not overwhelming them with instructions is helpful. Their hesitation to follow instructions may be fear instilled from a previous fall. Sight, hearing, taste and smell are all sensory modalities that decline with age. Older people have more difficulty with bright lights and tuning out background noise. Many elderly people become adept at lip reading to compensate for loss of hearing. For radiographers to assume that all elderly patients are hard of hearing is not usual; they are not talking in a normal tone, while making volume adjustments only if necessary, is a good rule of thumb. Speaking slowly, directly, and distinctly when giving instructions allows older adults an opportunity to sort through directions and improves their ability to follow them with better accuracy. Cognitive impairment in the elderly can be caused by disease, aging, and disuse. Dementia is defined as progressive cognitive impairment that eventually interferes with daily functioning. It includes cognitive, psychologic, and functional deficits including memory impairment. With normal aging comes a slowing down and a gradual wearing out of bodily systems bit it does not include dementia . Yet the prevalence of dementia increases with age. Persistent disturbances in cognitive functioning, including memory and intellectual ability, accompany dementia. Fears of cognitive loss, especially Alzheimers disease, are widespread among older people. Alzheimers disease is the most common form of dementia. Therefore health care professionals are more likely to encounter people with this type. The majority of elderly people work at maintaining and keeping their mental functions by staying active through mental games and exercises and keeping engaged in regular conversation. When caring for pati ents with any degree of dementia, verbal conversation should be inclusive and respectful. One should never discuss the patients as through they are not in the room or are not active participants in the procedure. One of the first questions asked of any patient entering a health care facilities for emergency service Do you know where you are and what day it is? The health care providers need to know just how alert the patient is. Although memory does decline with age, this is experienced mostly with short-term memory tasks. Long-term memory or subconscious memory tasks show little change over time and with increasing age. There can be a variety of reasons for confusion or disorientation. Medication, psychiatric disturbance, or retirement can confuse the patient. For some older people, retirement means creating a new set routines and adjusting to them. The majority of elders like structure in their lives and have familiar routines for approaching each day. PHYSIOLOGY OF AGING Health and well- being depend largely on the degree to which organ systems can successfully work together to maintain internal stability, With age, there is apparently a gradual impairment of these homeostatic mechanisms. Elderly people experience nonuniform, gradual, ongoing organ function failure in all systems. Many of the body organs gradually lose strength with advancing age. These changes place the elderly at risk for disease or dysfunction, especially in the presence of stress. At some point the likelihood of illness, disease and death increases. Various physical diseases and disorder affect both mental and physical health of people of all ages. They are more profound among elderly people because diseases and disorders among older people are more likely to be chronic in nature. Although aging is inevitable, the aging experience is highly individual and is affected by heredity, lifestyle choices physical health, and attitude. A great portion of usual aging risks can be modified with positive shifts in life style. In elderly, the aging of the organs systems is one of the process where they need to understands and there are as list below: Integumentary systems disorders Nervous systems disorders Sensory systems disorders Musculoskeletal systems disorders Cardiovascular systems disorders Gastrointestinal system disorder Immune system decline Respiratory system disorder Hematologic system disorders Genitourinary systems disorders Endocrine systems disorders. THE RADIOGRAPHERS ROLE The role of the radiographer is no different than that of all other health professionals. The whole person must be treated, not just the manifested symptoms of an illness or injury. Medical imaging and therapeutic procedures reflect the impact of ongoing systemic aging in documentable and visual forms. Adapting procedures to accommodate disabilities and disease of geriatric patients is a critical responsibility and a challenge based almost exclusively on the radiographers knowledge, abilities, and skill. An understanding of the physiology and pathology of aging, in addition to an awareness of the economic the social, psychologic, cognitive, and economic aspects of aging, are required to meet the needs of the elderly population. Conditions typically associated with elderly patient invariably require adaptations or modifications of routine imaging procedures. The radiographer must be able to differentiate between age related changes and disease processes. Production of diagnostic image s requiring professional decision making to compensate for physiologic changes, while maintaining the compliance, safety, and comfort of the patient, is foundation of the contract between the elderly patient and the radiographer. RADIOGRAPHIC POSITIONING FOR GERIATRIC PATIENTS The preceding discussions and understanding of the physical, cognitive, and psychosocial effects of aging can help radiographers adapt to the positioning challenges of the geriatric patient. In come cases routine examinations need to be modified to accommodate the limitation, safety, and comfort of the patient. Communicating clear instructions with the patient is important. The following discussion addresses positioning suggestion for various structures. The common radiography examinations for geriatrics are: Chest Spine Pelvis/hip Upper extremity Lower extremity CHEST The position of choice for the chest radiograph is the upright position; however, the elderly patient may not be able to stand without assistance for this examination. The traditional posteroanterior (PA) position is to have the backs of hands on hips. This may be difficult for someone with impaired balance and flexibility. The radiographer can allow the patient to warp his or her arms around the chest stands as a means of support and security. The patient may not be able to maintain his or her arms over the head for lateral projection of the chest. Provide extra security and stability while moving the arms up and forwards. When the patient cannot stands, The examination may be done seated in a wheelchair, but some issues will affected the radiographic quality. First, the radiologist need to be aware that the radiograph is an anteroposterior (AP) instead of a PA projection, which may make comparison difficult. Hyperkyphosis can result in the lung apices being obscured, and the abdomen may obscure the lung bases. In sitting position, respiration may be compromised, and the patient should be instructed on the importance of a deep inspiration. Positioning of the image receptor for kyphotic patient should be higher than normal because the shoulder and apices are in a higher position. Radiographic landmarks may change with age, and the centering may need to be lower, if the patient is extremely kyphotic. When positioning the patient for the sitting lateral chest projection, the radiographer should place a large sponge behind the patient to lean him or her forward. Sitting Chest PA Chest Standing SPINE Radiographic spine examinations may be painful for the patient suffering from osteoporosis who is lying on the x-ray table. Positioning aids such as radiolucent sponge, sandbags, and a mattress may be used as long as the quality, of the image is not compromised. Performing upright radiographic examination may be also appropriate if a patient can safely tolerate this position. The combination of cervical lordosis and thoracic kyphosis can make positioning and visualization of the cervical and thoracic spine difficult. Lateral cervical projections can be done with the patient standings, sitting, or lying supine. The AP projection in the sitting position may not visualized the upper cervical vertebrae because the chin may obscure this anatomy. In the supine position the head may not reach the table and result in magnification. The AP and open-mouth projection are difficult to do in wheelchair. The thoracic and lumbar spines are sites for compression fractures. The use of positioning blocks may be necessary to help the patient remain in position. For the lateral projection, a lead blocker or shield behind the spine should be used to absorb as much scatter radiation as possible. Lateral Spine PELVIS/HIP Osteoarthritis, osteoporosis, and injuries as the result of falls contribute to hip pathologies. A common fracture in the elderly is the femoral neck. An AP projection of the pelvis should be done to examine the hip. If indication is trauma, the radiographer should not attempt to rotate the limbs. The second view taken should be a cross-table lateral of the affected hip. If hip pain is the indication, assist the patient to internal rotation of the legs with the use of sandbags if necessary. Immobilization device are place to the patient foot. UPPER EXTREMITY Positioning the geriatric patient for projections of the upper extremities can present its own challenges. Often the upper extremities have limited flexibility and mobility. A cerebrovascular accident or stroke may cause contractures of the affected limb. Contracted limbs cannot be forced into position, and cross-table views may need to be done. The inability of the patient to move his or her limb should not be interpreted as a lack of cooperation. Supination is often a problem in patients with contractures, fractures, and paralysis. The routine AP and lateral projections can be supported with the use of sponges, sandbags, and blocks to raise and support the extremity being imaged. The shoulder is also a site decreased mobility, dislocation, and fractures. The therapist should assess how much movement the patient can do before attempting to move the arm. The use of finger sponges may also help with the contractures of the fingers. Hand Projection Lateral Wrist LOWER EXTREMITY The lower extremities may have limited flexibility and mobility. The ability to dorsiflex the ankle may be reduced as a result of neurologic disorders. Imaging on the x-ray table may need to be modified when a patient cannot turn on his or her side. Flexion of the knee may be impaired and required a cross-table lateral projection. If tangential projection of the patella, such as the Settegast method, is necessary and the patient can turn on his or her side, place the image receptor superior to the knee and direct to central ray perpendicular through the patellofemoral joint. Projections of the feet and ankles may be obtained with the patient sitting in the wheelchair. The use of positioning sponges and sandbags support and maintain the position of the body part being imaged. AP Ankle Projection Lateral Ankle Projection PATIENT CARE Patient care must be apply to geriatric patient because they all are all fragile where their bone can easily broke or they can be easily fainted during the examination. For communications, take time to educate the patient and his or her family, speak lower and closer, and treat the patient with dignity and respect. Transportation and lifting patient are also be need because geriatrics patient is not stronger than normal person. If possible, give the patient time to rest between projection and procedures. Avoid adhesive tape because elderly skin is thin and fragile. Provide warm blankets in cold examination rooms, use table pads and hands rails and always access the patients medical history before contrast media is administered. Take time with the patient Immobilization Device CONCLUSION The imaging professional will continue to see a change in health care delivery system with the dramatic shift in the population of persons older than age 65. This shift in the general population is resulting in an ongoing increase in the number of medical imaging procedures preformed on elderly patients. Demographic and social effects aging determine the way in which the elderly adapt to and view the process of aging. An individuals family size and perceptions of aging, economic resources, gender , race, ethnicity, social class, and the availability and delivery of health care will affect the quality of the aging experience. Biologic age will be much more critical than chronologic aging when determining the health status of the elderly. Healthier lifestyles and advancement in medical treatment will create a generation of successfully aging adults, which in turn should decrease the negative stereotyping of the elderly person. Attitudes of all health care professionals, whether positiv e or negative, will affect the care provided to be growing elderly population. Education about the mental and physiologic alterations associated with aging, along with the cultural, economic and social influences accompanying aging, enables the radiographer to adapt imaging and therapeutic procedures to the elderly patients disabilities resulting from age-related changes. The human body undergoes a multiplicity of physiologic changes and failure in all systems. The aging experience is affected by heredity, lifestyle choices, physical health, and attitude, making it highly individualized. No individuals aging process is predictable and is never exactly the same as that of any other individual. Radiologic technologists must use their knowledge, abilities, and skills to adjust imaging procedures to accommodate for disabilities and disease encountered with geriatric patients. Safety and comfort of the patient is essential in maintaining compliance throughout imaging procedures. Implementation of skills such as good communication, listening, sensitivity, and empathy, all lead to patient compliance. Knowledge of age-related changes and disease process will enhance the radiographers ability to provide diagnostic information and treatment when providing care that meets the needs of the increasing elderly patient population.

Disastrous Date

There was this time I went out on a blind date. OK, not totally blind, because I'd met this guy on the Internet, and had sort of seen pictures. But this is back in the day when Internet dating only first kicked off and digital cameras weren't what they are now. Anyway, you get the picture – the photos weren't that clear. I thought it was a bit weird that when we were corresponding the guy kept on asking how tall I was, making a real big deal out of it. In one email he said he even got out a measuring tape to convert (I only knew in cm's and he only knew in feet).Well my question was answered when I arrived (a bit late) at the fancy restaurant he had booked for us – he was tiny. OK, not that I have a problem with short guys, but I'm short for a woman, and he wasn't much taller. That and the fact that the guy was old enough to be my grandfather – early 60's at least – I was in my early 20's. In emails prior to meeting up he'd said he was older, but didn't gi ve out any specifics. I quite like older men, so it wasn't really something on the forefront of my mind, and I just assumed he'd be in the age category I had specified in my profile criteria.Well, let me just say this, there's older men and then there's just old. And this also has a lot to do with how much a guy looks after himself, his dress sense, his outlook on life etc. Dinner was long, drawn out and awkward as hell. We had zero things in common and the guy was really boring and from a totally different world and generation to me. He also had this habit of making a sort of ‘hmmmm' sound when he looked at me across the table which was totally creepy. I'm not sure if it was a nervous tick or if he thought it was a sexy kind of thing to do.At one point I had a brief vision of those small old hands touching my bare skin and I wanted to run out of there screaming. If a friend had told me this I would have said to her, why didn't you just leave? And the thing is it was such a fa ncy place, with the whole three courses, plus little things here and there from the chef, that it just didn't feel right to up and leave after the starters. Also, although we were unsuited to each other, this guy had clearly gone through some trouble to book a nice place and make it special, and I felt it would have been rude to just leave him stranded there.Finally dinner came to an end and I couldn't wait to beat it out of there. Outside he hailed a taxi for me and said in the same weirdly creepy old guy trying to be sexy voice, â€Å"You know, I don't have to be up early tomorrow morning, unless of course you want to be my alarm clock? † To which I replied (nervously laughing), â€Å"You know, unfortunately I do – have to be up early that is, maybe next time. † Before beating a hasty retreat. I guess I didn't come off much better in the date either, because I didn't hear from him after that.

The Potato Peeler Analysis - 1151 Words

The Potato Peeler (1885) (Fig. 1) (reverse: Self-Portrait with a Straw Hat) (1887) (Fig. 2) by Vincent van Gogh (1853-1890) is one of many paintings that lack highly saturated hues and colors by van Gogh. Many have a misconception that his darker and less saturated paintings come from a short time in his life when he experimented with dark colors; the reality is that his more saturated paintings were not developed until the last four years of his life and his less saturated pieces come from a longer period in his life. Given how different the two pieces are, one can assume they are unrelated; but they really show how much he grew as an artist and how much he challenged himself to move from less saturated still lifes, portraits, etc. to†¦show more content†¦Much, if not all, of his work before 1886 was very similar; he used vibrant color infrequently if it all and painted dark landscapes, still-lifes, and portraits (like The Potato Peeler). It was not until he left for France in 1886 that he decided to focus more on himself, thus transforming his style into what we recognize more easily today. There seems to be a misconception that he had always painted with vibrant colors and little thick strokes; but he only painted using vibrant and highly saturated colors for a brief time in his life as stated before. Van Gogh was influenced by Jean-Franà §ois Millet to paint rural scenes. In the winter of 1884 to 1885, van Gogh painted more that 40 portrait studies of peasants, including The Potato Peeler (Department of European Paintings). These studies would then lead to his piece The Potato Eaters as seen in Fig. 3. Van Gogh was inspired to portray rural life this way because he â€Å"intended to relay to the viewers a feeling of the coarseness of rural life† (Stotland, 387). Van Gogh was more focused on life around him and depicting it in a more humanistic way. Although the use of light and shadow may be exaggerated to some extent, the color stays accur ate to what humans do look like. A few more minor pieces were painted after in the same style as The Potato Peeler; but after his move to France, his style changes to the more vibrant and impressionist style we know today.

How Close Are We Really Artificial Intelligence - 1249 Words

How Close Are We Really to Artificial Intelligence? In The Hitchhiker’s Guide to the Galaxy, written by Douglas Adams, a man named Arthur Dent wakes up and finds himself at the beginning of beyond a bad day. When he learns that a friend of his is actually an alien with advanced knowledge of Earth s impending destruction, he is transported off the Earth seconds before it is exploded to make way for a new hyperspace motorway. And as if that s not enough, throw in being wanted by the police, Earth II, an insane electronic encyclopedia, no tea whatsoever, a chronically depressed robot and the search for the meaning of life, and you ve got the greatest adventure off Earth. Introduction Artificial Intelligence (AI) is a common subject found in many works of science fiction.
