Galileo Galilei Essay Example for Free

Galileo Galilei Essay Galileo Galilei is an Italian astronomer, physicist, philosopher, and mathematician. He ranks with Archimedes, Newton, and Einstein as one of the greatest scientists of all time. His discoveries, made with the crudest of equipment, were brilliant examples of scientific deduction. Galileo’s studies of natural laws laid the groundwork for the experimental scientists who followed him. Galileo was born at Pisa, the son of a musician who planned a medical career for him. He began studying medicine at the University of Pisa. According to legend, Galileo made his first major discovery at this time. He is said to have used his pulse to time the swinging of a suspended lamp in a cathedral; he found that, no matter how far the lamp swung, the timing has always the same (Drake, 2002). In later life Galileo established the fact that a free-swinging object, or pendulum, moves in uniform time intervals. Pendulum clocks are a common application of this principle. Thesis Statement: This paper scrutinizes the life and contributions of Galileo Galilei. II. Discussion Galileo constructed the first telescope used for astronomical observations; the observations he made supported Copernicus’ theory that the sun is the center of the solar system. In physics, Galileo discovered the principles of motion followed by swinging pendulums, falling bodies, and flying projectiles. Galileo used his heartbeat to time the period of a pendulum. He realized that a pendulum could be used as a standard of time for a clock (Rose 2004). Pendulum clocks are still sold today, more than three hundred years after their invention. Moreover, changing from the study of medicine to that mathematics and natural science, Galileo conducted experiments on gravity that brought him to public attention. In 1589, he became a lecturer on mathematics at the University of Pisa, and began his studies of falling bodies. According to legend, as mentioned earlier, he dropped objects from the Leaning Tower of Pisa to prove his theory that bodies fall at the same speed and with the same acceleration regardless of their weight and size. He also demonstrated that projectiles follow a parabolic path. These discoveries were contrary to the teachings of the ancient Greek scientist and philosopher Aristotle, many of whose ideas had for centuries been accepted without question. Galileo aroused such opposition that in 1951 he was forced to resign from the university (Rose 2004). The next year Galileo obtained a professorship in mathematics at the University of Padua, where he remained for 18 years. This was a period of successful research, acclaim, and prosperity for Galileo. In 1609, Galileo received news of the invention, in Flanders, of a device that made a distant objects appear larger. He immediately set out to build such a device for himself. The final result was a 32-power refracting telescope, with which he made series of major discoveries (Poupard 2005). He found by observation that the moon shone only from reflected light; that the Milky Way was formed of a multitude of stars; and that the planet Jupiter was circled by several moons. His discoveries caused great excitement among astronomers; he was besieged with orders for telescopes. In 1610, Galileo left Padua for Florence to become official mathematician and philosopher to Grand Duke Cosimo II de’ Medici. By the end of the year his telescopic discoveries included the rings of Saturn, the phases of Venus, and sun spots. His observations clearly confirmed the theory of the Polish astronomer Copernicus that the earth and planets revolved around the sun. The church, however, had accepted as conforming the Bible the earlier idea of the planets and sun revolving around the stationary earth. When Galileo visited Rome in 1611 he was given a welcome by Church officials befitting one of the greatest astronomers of all time, as he was then acknowledged to be. This gave him the courage to announce his support of the Copernican theory of the solar system. Controversy flared. Although warned by the Church to avoid religious interpretation of his theory, Galileo attempted to prove it by quoting the Bible. He was told by the Church in 1616 to abandon the Copernican theory because it contradicted the Bible. In 1632, however, he published Dialogue on the Two Chief Systems of the World, in which he revived his argument in favor of the Copernican system. Galileo was then summoned to appear before the Inquisition and forced to renounce the view that the earth moves around the sun (Poupard, 2005). Although sentenced to imprisonment, he was permitted to retire to his home, where he continued his studies. III. Conclusion As a conclusion, Galileo Galilei made great contributions to our society through his invention and discoveries. His works are highly acclaimed and made significant impact in the fields of mathematics, physics, astronomy, and in sciences. Reference: Drake, Stillman (2003).

When you dial 911 for an emergency, the outcome may very well depend on the 411 – the quality of information available on your condition and ways to treat it. Everybody will experience an Emergency Room visit at some point in their life, go through the extensive admittance process and will be expected to wait for a considerable amount of time before they get treated. The treatment might not come right away depending on the severity of the injury. But have you ever wondered why this always happens? It is obvious that hospitals are always busy; you’ll see nurses always running around and hear doctors’ names being called on the PA, all of this caused by the endless amount of people that get admitted every second of the day. What people aren’t aware of is that there’s an uprising problem that’s present throughout the whole healthcare system. The healthcare industry generates massive amounts of data every day, part of which is sourced and document ed from ancient times. Not every bit of information generated has been in a format readily understood by people in the medical field. To help better acquire, document and understand this information, and to create practical guidelines and applications in today’s healthcare industry, Health Informatics has been created as a discipline. Many medical informatics systems have been developed for maintaining patient records in the doctor’s offices, clinics, and individual hospitals, and in many instances systems have been developed for distributing information among multiple hospitals and agencies. But much remains to be done to make such information systems maximally useful, issues surrounding confidentiality and ethics plus the lack of funds and training pose as the biggest challenges. The advance... ...tics to Improve Environmental Health Practice† published in the Journal of Environmental Health, asserts that the Environmental Health Specialists Network Information System (EHSNIS) program has been implemented by the Center for Disease Control and Prevention’s National Center for Environmental Health to serve as a model of how health informatics would translate into the health environmental field. The EHSNIS’ main purpose is to accumulate data from numerous areas to track of a potential â€Å"foodborne and water-borne illness outbreak† (44). On the local to global scale an integrated informatics system would enable health professionals to detect and track natural health emergencies. More importantly this emphasizes on how the collaboration of two different organizations in making of an informatics system that could detect of a potential outbreak should serve as a model

History of Western Art Essay

It entered into the register in 1593 and was there for a period of 47 years. Venus is the goddess of love, while Adonis is a handsome mortal. The woman image (Venus) is seen, assisted by a small child, trying to restrain Adonis from setting off. The woman is naked while the man is in a hunter’s attire. Some hunting dogs are also seen by the man’s side. This painting shows only a small part of Adonis and Venus. The artist focused only on the two characters; Venus wanting Adonis’ embrace but Adonis is refusing and this is clear in the painting. It can also be seen that behind her, there are some flowers and a small thicket. In this painting the artist has tried to use the least poses or none at all. This makes it unique from most other paintings. Another ingredient of the uniqueness of this painting is that the artist has fairly restricted the gestures belonging to the two hovering figures. He has actually used calmness in such a situation that is so emotional. Le Dejeuner sur l’Herbe (1863) This was first presented to the salon in 1863. There is minimum use of lines. A naked woman with two men seated together in an absurd manner. At the background is another image of a woman slightly bending and appears to be bathing and facing the two men and the woman. The background is also dark as compared to the foreground. In fact, the woman looks brighter than anything else. The naked woman has her clothes spread all over with some food stuff in a basket at the lower side end, while one of her legs is stretched towards one of the men’s own space. How these two men are seated suggests that they have no business to do with the woman and they seem to be communicating with each other. Being ignored, this woman chooses to just look at the viewer shamelessly. On the other hand, the two men are in attire which is actually decent and it probably was fashionable during this period. And contours here have not been used; the artist has utilized light and paint. It is evident that a viewer’s emotional response will be determined by the image of the naked woman and at the first glance, will be left wondering about the situation that these two men are in; nicely dressed men sitting next to a blatant woman who has not even a single piece of a covering on her body, in fact on an open. Grande Odalisque by Ingres Created in 1814, it fit into the romanticism of between 1750 and 1850. It was fist shown in salon in 1819. It again has an image of a naked woman lying in something like a sofa and also posed in an unhurried manner. She has a small head, looking at the viewer, and a stretched out arms and legs. She has only shown her back and small part of her breast in the ingress painting; it is polished smoothly on the surface and has simple contours drawn round in a rhythmic manner. The eventful material by the woman’s side complements the smooth body planes. The painter seems to be bringing out a relationship between colors and tone in a way that it is hard for one to forget. During this period, the concubines had a duty of merely satisfying sultan’s bodily pleasures. For this purpose, the artist has symbolically elongated the area around her pelvis. Furthermore, the way this woman has posed and her position in relation to her pelvis is an illustration of how deep and complex the emotions and the thoughts of the woman are. The romantic founders cast-off some common approaches and looked for freedom of expression through their art work. By doing this, they concentrated much on freedom in self-expression, mantic love, individualism, and adventure. Another dominant concept they used is the inspirational idea of dealing with pain, terror, power and darkness. This, of course, is not difficult for humans. Hence romantic artists have engaged a variety of styles and ways in their work even in neglecting the strict academia. This is displayed by Ingress in his Grande Odalisque work. From the above, it can be seen that the three images differ in some way. First, how the paintings are done differs from one another. For instance, while we are have wide use of lines and contours in Grande Odalisque, minimal of these features are employed in the Le Dejeuner sur l’Herbe. another. The difference is that, the images were produced at different times and hence their themes are also different and each has a theme that is in line with the period it was created. Thirdly, we have different artists for the different images and as such since every artist has a different taste from another, definitely their work will be different. In as much as these differences exist, there are also similarities between these images. It is clear in all images that romance has been the major, or one of the major, themes and in every case the main character is a woman. Another major similarity is the nudeness of the women in every image. With all these, I still disagree that these nudes were consistent with the general trends of the period. This is because at some instances, the nudes behaved in a very awkward manner such as staying completely naked in public, and leaving the viewer questioning their moral standards. The difference is as a result of the fact that the artists have different ways of symbolizing events ant ideas and, as said earlier, they have different tastes. The similarity is as a result of the fact that each of the artists wants to divert from the tradition of the academic style and wants to embrace freedom. Every artist in these three images has shown the woman to be the major character and a suitable object of bringing out the real feeling of what each of them wants to communicate. Nudeness was actually such an enduring subject in western art because every one of the images tries to bring out a theme in the best way possible and every artist did not want to be left behind and subject of the nudes had to be considered by them.

Many African-American activist fought and died for African-Americans’ rights. There would only be nuance, but today things are going downhill again. Today, the stereotypes of African-Americans are put upon me. I am often judged due to my race. I have been treated intellectually inferior multiple times. People often assume me to be living in poverty and fatherless. Sometimes, people are suspicious of me due to media and newscasts displaying African-Americans as criminals and dangerous. Due to my color, people even believe silly things like me having a love for watermelon, grape soda and fried chicken. Although, none of those things are true about me.
