Astronomy from Prehistory to Galileo

Astronomy from Prehistory to Galileo Astronomy and humanitys interest in the sky are almost as old as the history of intelligent life on our planet. As civilizations formed and spread across the continents, their interest in the sky (and what its objects and motions meant) grew as observers kept records of what they saw. Not every record was in writing; some monuments and buildings were created with an eye toward a link with the sky. The pyramids in Egypt, for example, not only housed the remains of their Pharaohs, but some were also aligned with certain star patterns and stars. Nearly every culture had a connection to the sky. Everybody also saw their gods, goddesses, and other heroes and heroines reflected in the constellations. The motions of the Sun, Moon, and stars had ritual meaning, and many tales invented during the ancient epochs are still told today. This fascination with sky objects may date back tens of thousands of years, and some primitive art examples, such as the caves at Lascaux, France, have paintings that appear to show constellations and star patterns. Beyond the ritual and sacred perceptions of the sky, however, people were moving from a simple awe of the sky to an understanding of the motions of celestial objects. They used a connection between the sky and the seasons, and ways to use the sky to create calendars.  Ã‚   Early Neolithic people are thought to have built Stonehenge in England as a connection to the sky. It seems to have a link to Moonrise and Moonset times throughout the year. Orion Lawlor Using the Sky What most historians find quite interesting today is how humanity moved from merely charting and worshipping the sky to actually learning more about celestial objects and our place in the universe. Theres plenty of written evidence of their interest. For example, some of the earliest known charts of the sky date back to 2300 BCE and were created by the Chinese. They were avid skywatchers, and noted such things as comets, guest stars (which turned out to be novae or supernovae), and other sky phenomena.   The ecliptic is the path that the Sun, Moon and planets appear to follow in the sky throughout the year. The constellations that appear along the ecliptic are called the zodiac constellations. These had special meaning to early astrologers, who used them in rituals and to attempt to predict events. Carolyn Collins Petersen The Chinese werent the only early civilizations to keep track of the sky. The Babylonians first charts date back to a couple of thousand years BCE, and the Chaldeans were among the first to recognize the zodiac constellations, which is a backdrop of stars through which the planets, Sun, and Moon appear to move. And, although solar eclipses have occurred throughout history, the Babylonians were the first to record one of these spectacular events in 763 BCE.   Explaining the Sky Scientific interest in the sky gathered steam when the earliest philosophers began pondering what it all meant, both scientifically and mathematically. In 500 BCE the Greek mathematician Pythagoras suggested that Earth was a sphere, rather than a flat object. It wasnt long before people such as Aristarchus of Samos looked to the sky to explain the distances between stars. Euclid, the mathematician from Alexandria, Egypt, introduced concepts of geometry, an important mathematics resource in most of the known sciences. It wasnt long before Eratosthenes of Cyrene calculated Earths size using the new tools of measurement and mathematics. These same tools eventually allowed scientists to measure other worlds and calculate their orbits. Aristarchuss calculations on the relative sizes of the Sun, Earth, and Moon. These were done in the 3rd century B.C.E. Public Domain. The very matter of the universe came under scrutiny by Leucippus, and along with his student Democritus, began to explore the existence of the  fundamental particles called atoms. (Atom comes from the Greek word meaning indivisible.) Our modern science of particle physics owes a great deal to their first explorations of the building blocks of the universe.   Our modern attempts to understand the structrure of the atomn (as shown in thise artists concept) are based on ancient Greek explorations of the nature of matter. Science Photo Library/Getty Images Although travelers (particularly sailors) relied on the stars for navigation from the earliest days of Earth exploration, it wasnt until Claudius Ptolemy (more familiarly known simply as Ptolemy) created his first star charts in the year 127 AD that maps of the cosmos became common. He cataloged some 1,022 stars, and his work called The Almagest became the basis for expanded charts and catalogs through the succeeding centuries.   The Renaissance of Astronomical Thought The concepts of the sky created by the ancients were interesting, but not always quite right. Many early philosopher were convinced that Earth was the center of the universe. All else, they reasoned, orbited our planet. This fit well with established religious ideas about the central role of our planet, and humans, in the cosmos. But, they were wrong. It took a Renaissance astronomer named  Nicolaus  Copernicus  to change that thinking. In 1514, he first suggested that Earth actually moves around the Sun, a nod to the idea that the Sun was the center of all creation. This concept, called heliocentrism, didnt last long, as continued observations showed that the Sun was just one of many stars in the galaxy. Copernicus published a treatise explaining his ideas in 1543. It was called  De Revolutionibus Orbium Caoelestium (The Revolutions of the Heavenly Spheres). It was his last and most valuable contribution to astronomy.   The status of Copernicus in front of the Jagiellonian University of Krakow, Poland. photo muguette/Getty Images The idea of a Sun-centered universe didnt sit well with the established Catholic church at the time. Even when astronomer Galileo Galilei used his telescope to show that  Jupiter was a planet with moons of his own, the church didnt approve. His discovery directly contradicted the holy scientific teachings. Those were based on the old assumption of human and Earth superiority over all things. Galileos writings were extensive chronicles of his work, although they were suppressed for a time. That would change, of course, but not until new observations and a flourishing interest in science would show the church how wrong its ideas were.   Galileo Galilei began the era of modern astronomy when he turned a telescope to the sky. His actions unleashed events that reverberated into the 20th century. Library of Congress. However, in Galileos time, the telescopes invention primed the pump for discovery and scientific reason that continue to this day.  His contributions and those of other ancient astronomers remain important in modern astronomy. However, for astronomy to advance, it had to move beyond small telescopes and naked-eye observations. The centuries following Galileos lifetime would bring astronomy into its own as a separate scientific discipline. Key Takeaways People have been interested in astronomy as long as they have been able to look up.The first astronomers used the sky as a calendar and time-keeping device, following as the stars changed daily and over the seasons.Cultural interest in the sky led people to associate constellations and certain stars and planets with their gods, goddesses, heroes and heroines.The Greek, Babylonian, Chinese, and other early astronomers began charting the skies.The Greek astronomy was used by the Romans.The first parents of modern astronomer were Copernicus and Galileo.

Answer for few Questions - Assignment Example The rate of criminalization was high in African Americans which lead to black power movement. In 1964, the Black power movement became the civil rights movement as the Democratic Party declined to seat Black Mississippi Freedom Democratic Party (MFDP) (Gilmore, 1998.pp.175). When Black Americans realized the fact that there was no hope for them to obtain equal rights as White Americans, this issue then became the cause of major disorders and riots all over the land. Racism has played an important role in making the criminal history of the United States of America. The inequality in terms of economic rights and social rights caused the Black Americans to become violent. The white people were the true players who fought battles against people of color and different races. Surplus The essential fact behind this crime scene was that moral panic was greater than the crime. There are many crises which combined and resulted in the form of prisons and prisoner. There are social crisis and ec onomic crisis. The history of the crimes and prisons has roots indeed. The United States had the surplus ideology in the name of defence. Whether it was a conflict against Native Americans or the anti-capitalist movements there have been many crises in the history of the United States. During the period of 1970s the nation faced depression and there were surplus of crisis. The consequences of 1973-7 recession were combined with the surplus of 1981-4 recession and again in 1990-4. (Gilmore, 1998. pp 177). Prison Industrial Complex The Prison Industrial complex is the term first used by activist and the scholars to refuse the common thought that the increased rate of crime is the reason of constructing prisons. They argue that the main causes of the increased population of these prisons are profits and racism. There is exploitation of prisoners and the prisons by the big corporations, government and the communities (Davis, 2003.pp. 84). The 13th Amendment The thirteenth Amendment to t he United States constitution officially outlaws slavery except as punishment for crime (Davis, 2003.pp. 23). On April 8, 1864, it was passed by the senate and adopted on December 6, 1865. There was a history of slavery in the United States and it was abolished later, but the concept was so prominent that white abolitionists even found it difficult to imagine Black people equal. After the abolition of slavery, its effects on the society were still present in the forms of lynching and segregation. There is a relation of prisons to the slavery, segregation and lynching because all these social institutions like prison were considered as everlasting as sun. It can be clearly observed that slavery resulted due to racism and there is several evidence of prisons working as racist institutions and they are obsolete, whereas racial discrimination is also observed inside the prison walls and among prisoners. We just consider racism in terms of black and white, but we ignore racism in term am ong colored people. After the September 9, 2011, the mass of people were arrested who were Middle Eastern, South Asian and mainly Muslims. So, the question arises are prisons racist institutions? If it is the case, then like racism the prisons are also obsolete. Prisons are a â€Å"geographical solution to socioeconomic problems†

Team Communication Essay Example | Topics and Well Written Essays - 1000 words

Team Communication - Essay Example However, many people involved into this type of interpersonal relations are not fully aware about the rules and logic of team communication. This knowledge is especially important for those who supervise and direct work of teams, namely managers and coordinators. These people spend most of their working hours communicating with their subordinates: participation in planning, organizing, controlling, and supervising activities, preventing and resolving conflicts between the personnel, scheduling and many other tasks that define the nature of team work. Communication between people is a very complex process that includes several equally important aspects. Defining it as a process we mean that it is not static set of behaviors or object we can hold in hands. As David Berlo (1960), the famous expert in team communication, believes, "if we accept the concept of process, we view events and relationship as dynamic, ongoing ever-changing, continuous. When we label something as a process, we also mean that it does not have a beginning, an end, a fixed sequence of events. It is not static, at rest. It is moving. The ingredients within a process interact; each affects all of the others" (p.6). Team or group communication includes "a relatively small number of persons who have a mutually interdependent purpose and a sense of belonging, demonstrate behavior based on norms and values, use procedures accepted by the group, and interact orally" (Pearson, 1994, p.211). This definition mirrors the structure of team communication. Social psychologists long ago identified certain circumstances under which group communication is more appropriate than any other: 1. When a variety of entirely different ideas is better than several ideas that have much in common. Presence of others involved into similar activity encourages the process of thinking in each individual member of the group making them generate new ideas. 2. When members of the group express a strong desire to be involved into the process of decision making and discussing problems. In such situation, group communication helps avoid tension that would have inevitably appeared in case the group's members are denied such opportunity. 3. Team communication plays the key role when commitment of its members is at stake. It is a common knowledge that decisions put into place without agreement of people whom they concern have good chances to meet unexpected resistance. For instance, if a manger determines his subordinates' duty list without discussing it with them, there is a great probability that majority of the subordinates will express strong resistance. 4. And sometimes when a group decision is an essential condition it is appropriate not to ask the members privately, but to let them discuss the problem in group and made a common decision (Pearson, 1994, pp.211-214). Presence of others dramatically transforms behavior of separate individuals as well as their way of thinking. In order to understand the reasons for these changes we should analyze the unique characteristics of small groups, and first of all group norms, roles, leadership, member satisfaction, commitment, and productivity. Norms is a distinctive characteristic of groups. Basically, norm is "an expected standard of behaviour and belief established and enforced by a group" (Franzoi, 1996, p.261). The word "standard" includes

Analysis Of A Modern China Family English Literature Essay

Analysis Of A Modern China Family English Literature Essay Pa Chins Family is a historical, semi-autobiographical narrative of the hardships endured by the members of an aristocratic family during the massive transformation in Chinese social and political order that took place during the early 20th century. The central conflict that is embodied in the novel is the inability of the individuals portrayed in the narrative to move past the often oppressive traditional social constructs that prevent them from moving forward in light of the new revolutionary paradigm that was sweeping the country. Three brothers, Chueh-hui, Chueh-min and Chueh-hsin, are the central figures in this narrative, and the struggle to balance the responsibilities imposed upon them by the traditional order and their desire for radical change defines the essential subject matter of the novel. These conflicting desires tear them apart and force them to either adapt or be left in the past. The work embodies the voice of a nation that was steeped in contradiction, and demonstrates throughout its passages strong underlying themes of societal disillusionment and unrest. By offering a unique insight into the most personal aspects of life during this tumultuous period of Chinese history, Family offers the historian a critical perspective on the psychological underpinnings of a society undergoing fundamental changes in structure. The increasingly pronounced dichotomy between old and new is critical to the understanding of the narrative in this story. This is represented at numerous avenues, but is revealed most blatantly in a sequence where Chueh-huis ponders upon his grandfathers sleeping body and through careful analysis comes to the realization that the old man ultimately represents not his grandfather, but an entire generation and that he himself was similarly the representative of his own generation. Reflecting further upon this observation leads him to the conclusion that they could never see eye-to-eye. (Chin 64). This conclusion is important, and foreshadows the inability of China to reconcile the two radically divergent world-views; there would be an ultimate clash between traditionalism and socialist progressivism that tears apart not only the country, but all the bonds that are held within. This antagonism between the old and the new similarly crosses historical lines, with historical texts demonstrating a fundamental disconnect between the traditional constructs that served as the guidance of Chinas actions on the world stage for generations and a powerful need for reform that threatened to sweep away these traditional systems. In Madame Sun Yat-Sens public address concerning the political left, she opens with the following: if China is to survive as an independent country in the modern struggle of nations, her semi- feudal conditions of life must be fundamentally changed and a modern state created to replace the medieval system which has existed for more than a thousand years. This task needs to be done by the method of revolution (Cheng Lestz 267). Statements such as these reflect a growing animosity towards traditional social constructs, in this instance painting them as medieval. This attitude is indicative of an unwillingness to compromise with the past in order to move forward it must be burned away to make room for the new. Critically, it must be recognized that the ultimate impetus of this rebellion was not reform for the sake of general development or even reform for the purpose of furthering China as a nation, but as a means to catch up with the West. Here we see a marked transformation; China is no longer the smirking, dominant nation who expects Western nations to cow-tow to the whim of the Emperor, but a third-rate nation with a collapsing political system that is forced to play catch-up to the burgeoning Western powers. A palpable sense of inferiority can be observed when reading political material originating from this period, permeating all layers of Chinese society. The New Life movement can be seen as an extension of this pathological national insecurity; it is an attempt to emulate the West. In Madame Chiangs address on the matter, she states that Each nation, according to its lights, has sought to find a way out of stagnation into normalcy. Italy has its fascism, Germany its Nazism and America its New Deal (Cheng Lestz 295). This can be interpreted as indicative of Chinas interests to pursue the developmental patterns of the West; in the psyche of the Chinese they can no longer carve their own path in history only hope to follow the path of the West without losing the essential Chinese spirit, which is largely based on Confucian values. This attempt to reconcile the past with the present parallels many of the hardships endured by the brothers in Family. An interesting aspect of the story is the employment of the third-person narrative in order to divulge the various characters in the story in a setting where there is clearly a great degree of confusion regarding social and moral normality. By nature of this form of narration, we are sometimes limited in the psychological motivations and inner feelings of many of the characters in the novel. This is an important plot device in some instances; we do not learn anything of Master Kaos innermost thoughts until just before his death, at which point he is revealed to be a man of a good nature who holds only the best intentions for his family. In the narrative, three promising young women are ultimately destroyed by the family: Ming-feng, Jui-cheuh and Mei. This serves not only as the reason for Cheui-huis decision to abandon his family and, by extension, the traditionalist teachings of Master Kao, but a statement of the way in which traditional Chinese society exploits women in such a manner as to deprive from them the will to live. Despite the seeming lack of regard for their welfare, loss of the women is felt acutely by all members of the family, considerably more so in comparison to Master Kao, where after his passing the major concern is the dividing of his wealth and assets (Chin 295-296). This belies the fact that there was little love for the harsh Master amongst these closest to him; the love is a fascade, like all things in the traditional life. The death of Jui-cheuh was especially hard on Cheuh-hui, who felt that the baby was an enemy who had taken his beloved, then went so far as to blame the entire social order and, by extension, his own conformity to the traditional order, for having made him so weak as to be unable to save the two women that he loved: What had taken his wife away was something else. It was the entire social system, with its moral code its superstitions. He had borne them for years while they stole his youth, his happiness, his future, the two women he had loved most In the world. They were too heavy a burden; he wanted to shake them off; he struggled (Chin 309). Throughout the novel we are confronted with a Cheuh-hui that is deeply troubled by his inner hatreds and insecurities; here it is manifested in a way that is blatant to the reader and presented in a way as to make the deep-seated societal dysfunction that is the underlying theme of the novel explicit in a dramatic fashion. In Family, the brothers are ultimately driven apart, with Cheuh-hui leaving in disgust of the events that had taken place, and unable to reconcile with the past. Similar changes had also taken hold of the other brothers, whom had turned against the family either in fact or in spirit with a deep chasm growing between the siblings with the elapse of time only narrowly being reconciled by last-minute efforts to make peace with one another. Examples of such attempts include Master Kaos assertions that Cheuh-hui was a good child (Chin 289) and Cheuh-hui promising Cheuh-hsin that not only would he write, but that they would surely see one another again in the future. It is a hopeful yet sad parting, with each of the brothers attempting to make good with one another in the recognition of the fact that they have all been forced to endure extreme hardship. Family is the biography of a China that cannot reconcile with itself through any means other than destruction of the old. As Cheuh-hui is forced to endure the loss of everything that he has cherished in his life in order to break free of the traditional order that has bound him to a life that is filled with sorrow and anger, China is also forced to contend with a similar situation . Change does not and cannot come as a compromise, such as Chiangs New Life movement, but as a radical communist insurrection that simply erases the past and sews the seeds of a new future. While some of his brothers may be more willing to accept the family even in the face of its inevitable destruction, Cheuh-hui embraces the uncertain future; he recognizes that he can only move forward if he does not look back.

Discuss the concepts of the Ideal Ruler

1. Gilgamesh, as a ruler, has portrayed a character that stirred up the necessity of having a leader who does not just have the time but also the passion for service. He drew his strength in leadership from his intelligence, bravery and respect. It was his skills that encouraged social consciousness among his people that heightened their aspirations to search for answers for the freedom of his city. Amidst his many battles, he has been grateful to God for the skills that he has.The image of a warrior and a soldier being an epitome of discipline and bravery among all the people in his city appealed to Gilgamesh greatly. Gilgamesh has shown his strength when he made it to the top of double cliff of Mt. Mashu on his way to Utnapishtim. Apparently, this is just one of the rather resilient moments of Gilgamesh. The ruler, who, at all times, exhibited instances of valor, made his journey while holding characteristics of a true hero. 2. The Odyssey was a great epic led by the main character , Odysseus who holds a group of men for more than years.He led the group for years and all this he did with an innate love for his country, his crew and his self. The inevitable fact however comes with its entire weakness when Odysseus pursued his plan of getting through the walls of the Trojans by making a giant wooden horse. Odysseus had one man to present the giant horse to the Trojans as a sign of peace. Not knowing what’s inside the horse, King Priam of Troy, freely accepted the gift and had merriment together with his people.After such, when everybody was falling asleep, Odysseus and his men sneaked out from the wooden horse and murdered every man in the palace, including the King. Odysseus was known for his bravery and brilliant minds. But like any other ordinary hero, he too, has his own weaknesses. As a leader, Odysseus demonstrated a deceitful act towards the Trojans and seldom reserved his humble personality because of his pride.Despite everything though, he was ab le to portray the good traits of a true leader – clever and gallant, that is. . Augustine, a man of â€Å"mystical piety and great philosophical acumen† was always hungry for knowledge. And this carnivorous-like desire entrapped him to be enamored with different philosophies and works – Manichaeism, Platonism, and Cicero’s Hortensius. These might have influenced him to write the greatest of his writings – Confessiones, De Trinitate, and De Civitate Dei – but they don’t hold a candle to what move most believers, Augustine’s conversion. Augustine’s faith was not handed to him on a silver platter.It was a faith earned even if it took all his life to achieve it. He was rather free in choosing his own religion. But in August of 386, Augustine was subjected to incessant pressure from the stern ethical demands of the preaching Ambrose, the Bishop of Milan. Augustine was worried and was carried by anger to his own self for rejec ting the will of God and for not entering into His covenant (Confessions 8. 8). And as he stood there in the garden, he heard the voice of a child saying, â€Å"Tolle lege,† which means take it and read.Augustine took the Bible and read the first passage he came upon, Romans 13:13-14. And after reading such passage, he underwent a dramatic metanoia, a profound life-transforming experience wherein all his human desires were completely surrendered to God. 4. Oedipus’ being a King is no surprise for he was born as a prince. The people of Thebes had seen evidence of that. He was raised as a leader in a group of men who were happy during his time of leadership. He took responsibility on his people and was doing well on it. But what weaken him most were his low temperance and his pride.He couldn’t take hold of it for long that sometimes it was the only thing that was pulling him down. One instance that described how low-tempered Oedipus, was the time when he crossed t he highway and had a group of people before him. He wanted to go ahead of them and because of his impulsiveness; he jumped off and killed the group excluding one man who was leading it. With the scene, it can be concluded that despite his being a good leader and a king to his people, he too, can be as evil as any wicked beast could be to anyone who may break off before him.

Ethical and Legal Implications of Working with Alzheimers Disease Free Essay Example, 1500 words

As noted by the World Health Organization, dementia is a mental condition characterized by deterioration in behavior, memory, performance, and thinking when undertaking daily activities. These occurrences are termed abnormal because they do not characterize normal aging processes. Today, there are 36 million people suffering from dementia and the numbers are rising since 7.7 million cases are reported annually throughout the world (Murray, 2012). Therefore, individuals are at a risk of developing these mental complications in old age. According to the World Health Organization, increased cases of dementia are explained by interplay with Alzheimer s disease. According to Murray (2012), Alzheimer s disease is the primary cause of Dementia with unimaginable economic costs to the country and the world. Dementia is responsible for dependency and disability among elderly adults, and its influences on family, caregivers, and the community may have physical, social, psychological and econom ic origins. In 2010, the World Health Organization argued the social costs of dementia reached 604 million dollars, which corresponded to 1% of the global Gross Domestic Product. Moreover, as a proportion, the total cost varied from 1.24% in developed countries to 0.24% in developing countries.
