Brandon asked Anna out. It was a gloomy day with black heavy clouds threatening a storm. He was with his friends when Anna was walking home. He said: â€Å"Hey Anna, wow you look so grown up and beautiful. I want to invite you over at my house. Just some movies and stuff.† His friends sniggered. Anna didn’t care. She was in heaven and tried to look like she thought about it first before saying a nervous â€Å"Okay.† His friends left them. Inside the house, they watched a porn movie. It made Anna uncomfortable. The video looked amateur. Boys were breathing deeply at the background and it was dark. Brandon groped her breasts and whispered: â€Å"Let’s do it.† Anna said no, but she felt dizzy and weak.

The impact of the first world war on international relations in the decade after 1918 Essay Example for Free

The impact of the first world war on international relations in the decade after 1918 Essay In the fall of 1918, the allied forces won victorious on all fronts. An Armistice ended the fighting on November 11th 1918.During the four years of war between 1914 and 1918; there were immeasurable devastations, which left no aspect of civilization untouched. It was described by German General Erich Ludendorff as totalitarian war1 with human casualties, social consequences and economic consequences. These consequences made Allied leaders to meet in Paris from January through June 1919to draft peace terms; so that such wars should not happen in future. 2In order to achieve this, they agreed in creation of new world order to replace the four great Empires and satisfy expectations that this could be a worldwide settlement and would be permanent. Because of the devastations this war inflicted on humanity, nations were eager to form relations to avoid the future world war. This essay therefore attempts to look at factors that contributed to international relations, as seen by the new world order which was central to the fear of Bolshevism and autocratic government and the leadership during the mid 1920s. One of the agendas at the Peace Conference was the creation of International order to replace the four great empires. These were; the German, Russian, the Austro-Hungarian and Ottoman, that had previously structured Central Europe, the Balkans and the principle of self determination so as to liberate the wrongly supposed aspirations of nationality groups, whose struggles for independence was a cause also to war.3 Some new states which were created are; Estonia, Latria, Lithuania, and new Poland. After assuring their own stability in the summer of 1919, these nations were to act according to General Rudiger Vonder Goltz as the fluid borderlands of Eastern Europe. Apart from gaining their own independence, these nations were to help remove border conflicts that would have emerged between German and Russia. This is true when one examines Lenins reasons for accepting the treaty of Brest-Litovsk, which was for the benefit of Bolsheviks. He wanted the Bolsheviks to gain peace so that there could have been a time to organize and strengthen itself within Russia.4Frankly speaking, the Russians were not happy with it and it was very likely that they would reclaim their land as seen by Stalins aims of recouping most of the Rest Russias 1917 losses in the summer of 1940.5 Apart from states that were created between the borders of Germany and Russia, there were also other states created from Austria, Hungary and Ottoman Empire. These states are Austria-Hungary, Czechoslovakia, Romania, Croatia and Yugoslavia. One of the aims of Paris Conference was to remove secret diplomacy and give way to free and open discussions to international issues. In this way, the beneficent influence of the public opinion would be taken advantage of, and secretive intrigues of Imperialistically inclined national leaders would have their rows minimized.6 Although there was this advantage, some states created by the Peace Settlements made little economic sense. For example; the new countries of Austria and Hungary, which were small ad weak and unable to support themselves. They had most of their population, resources and markets. Austrias largely German population had wanted to unite with Germany, but the Peace treaties forbid that Union.7This was because the peacemakers did not want German to gain territory after the war. On the broader view, these problems cemented the relationship between powerful states (like Britain and France) with these smaller states in that there was dependability between these states. For example in the case of France whose major eastern ally since 1892, Russia materially weak and politically hostile, Frenchs security needs would be doubly served against Germany and against Bolsheviks.8 The other reason for new international order was that all internal political institutions of Europe would be democratized so as to remove autocratic constraints on public opinion that had permitted the ruling elites of the central powers to wage their war of aggression. For example, the Reichstag (German Parliament) was to be elected by universal suffrage and proportional, and the government was made responsible to it. The President was to be directly elected by the people in U.S.A and he was given wide emergency powers. The first elected President was Albert.9 In Constantinople where the allied military administered until the treaty of Sevres, which guaranteed the Greeks to stay in Turkey for fie years until it was democratized.10 Although the Sultan was ready to accept the treaty term, Turkish nationalities werenot. This is what led to nationalism led by veteran General Mustafa Kemal backed allied assistance to demand the retention by Turkey, of all territory inhabited by an Ottoman Moslem majority and to capitulate. General Mustafas main aim was to transform Turkey from Asiatic into a European country. By Europeanizing, it meant that Turkey was to democratize its all institutions in accordance to Britain or France. Because of these ideas of modernizing Turkey, she stood on a good relationship with her neighbors (Greece, Romania and Yugoslavia) who formed a common front to combat fascist threat as it was increasing.11From this it can be said the new international implemented by the League, of free and independent nations empowered to solve disputes by negotiation and compromise in the process maintaining international relations and peace. Another factor that made the nations to come together after the First World War was the fear of Bolshevism. By 1917,protracted war was producing revolutionary strains on all the belligerent countries. For example, in Russia, they could no longer contain the pressures of war weariness, social conflict and national separitism. These were the reasons, which made Lenin to organize the Bolsheviks who overthrew the provisional government in what is commonly known as the October revolution of 1917.12 In the years that followed, there was a civil war from 1918 to 1920.In this civil war; the Allied forces actively supported the Mensheviks, though they never took direct combat roles in this war. The unsuccessfulness of the Mensheviks was because they were disorganized and that workers who believed that the allied forces were helping the Mensheviks so that they should maintain that old system of landlords and tenants did not support them. Because of their disorganization and little support they received from workers, the Bolsheviks used this weakness, successfully won, and established themselves. The triumph of the Bolsheviks created a second European center of attraction and aspiration. There was fear of Bolshevisms and this made premier Clemenceau to understand that a harsh peace with Germany would spread Bolshevism into Germany. 13 Even though the relationship between Germany and the Allied nations was not good during this period of time, there were also some Germans who were asked by Allied nations to volunteer themselves under Rudiger Vonder Goltz to remain in the borderlands of Eastern European 1919.These acted as de facto allies of the western powers against Bolsheviks.14From this, it can be deduced that the fear of the Bolsheviks was bringing nations together. According to historians, the first five years after the war were years of hostility between Allied nations and Germany. Because of these Bolsheviks, Germany even volunteered herself to work hand in hand with Allied nations to avoid spread of Communism. This shows that despite the hostility that was there, they all had a common enemy to fight against and this eventually brought them close to the Allied nations. The change in leadership helped to ease international tensions which were there before 1924.The period between1918 and 1924 can be described as a period of tensions which would have disturbed the relationship among nations in the aftermath of world war One. There were problems that arose from the Paris Peace settlements and the League of Nations struggled to sort out the problems. For example, Turkey and Italy were dissatisfied with their treatment. The Turkish people were prepaid to defy the settlement because of huge territorial losses. The Italians who later came under the rule of Mussolini in1922, showed their resentment by seizing Fiume, which was previously given to Yugoslavia. 15 The problems in questions can be attributed to leaders who shaped the Peace Conferences in work as a national and self-interest of principal victors. Premier GeorgesClemenceau, in particular represented France with keen awareness that his people had withstood the worst of the Allied war effort and must withstand the worst of enforcing the peace terms on the continent of Europe. He was determined that the peace terms should favor the French.16To prove that the peace conference was for their self-interest (victorious nations), the defeated powers were not invited during the drafting of the peace terms, for there was a role that called merely for signing of the completed documents. Because some nations were not consulted but were forced to sign, some commentators have described it as a dictated, not negotiated peace. Furthermore, when Germany raised the question of Moratorium after experiencing greater inflation of the currency, just after the first payment, a partial of it was granted. When she attempted to make her revised payments, the mark again sank and she requested a moratorium on all cash payments until January 1925.Because the then leaders were not ready to help each other, the reparations problem for a time ceased to be merely a question between Allied forces and Germany and resolved itself into a diplomatic conflict between the British and French government.The problems arise because Britain wanted Germany to regain her prosperity and with it, her ability to purchase British commodity and improve her economy. While France wanted immediate reparations to resolve the region which was devastated by the war, she believed that Germanys fiscal difficulties were chiefly caused by its bad administration of finance and by bad faith of her nationals who were deliberately evading taxation and sending millions of dollars in gold and security out of the country. Because of these differences and their uncompromising attitude, a conference was called and it was held at Genoa in April 1922to discuss world economic problems and to try to get the Soviet Union to repay tsarist debts to Allied nations.( ) Because of Frances attitude towards Germany at the Conference, it helped to push the two main outsider nations; Weimer Germany and Soviet Russia into each others arms, hence Rapallo treaty between Russia and Germany. Come the second half of 1920s, there was a general improvement in the International atmosphere caused partly by a change in political leadership. In France, Edouard Herriot and Foreign Minister Aristide Briand, in Britain, Ramsy Mac Donald, and in Germany, Gustar Streetman came to power and all were keen to improve their relations. The result of this was Dawes plan. It was formed in London in 1924 and it was an attempt to break the dreadlock. Because leaders were eager to reconcile, they agreed that Germany should pay annually only what she could reasonably afford until she became more prosperous. Apart from the European leaders mentioned above, who were eager to reconcile, U.S.A. was also willing to help and it was in fact America, which granted loan of 800,000,000 (eight hundred million) gold marks to Germany.( )In1925, came the most important one in which Germany, France and Belgium promised to respect that joint frontiers. Thus, if one of the three broke the agreement, Britain and Italy would assist the state that was being attacked. This agreement was greeted with wild enthusiasm all over Europe and the reconciliation between France and Germany was referred to as the Locarno honeymoon( )The most significant feature of the Locarno agreements was the spirit of hope they had awakened in Europe. In heady mood, the major European State, U.S and Japan (with other countries totaling 65), included with the Kellogg-Briand Pact on August 27th, 1928.The signatories promised to renounce war as an instrument of national policy, ( )although no means of enforcing this promise were included in the pact.It is also sufficed to note that the dying out of tensions in Europe not only encouraged international relations, but also economic boom in these European states. Long at last, European states returned to normal. This essay has assessed the impact of world war one on international relations. Among other things, international relations were disturbed by the Peace settlements. Some nations were not happy with the terms of the Versailles treaty. However, despite this, other factors helped to cement the relations. These were: the new world order, fear of Bolsheviks and change of leadership during the second half of 1920s.Governments continued to deal with each other in secret and the interest of the states (as perceived by each, of course) continued to be the driving force of international relations. The First World War had nevertheless profoundly and permanently altered foreign relations. The tensions relaxed and a period of calm and prosperity followed in the late 1920s.

The Great Gatsby -The Valley of Ashes versus Toms House :: essays research papers

F. Scott Fitzgerald's The Great Gatsby is, at first sight, a novel about wealth, idealism, and social class. However it soon reveals its author’s true intensions and ideals. F. Scott Fitzgerald uses symbolism to produce immense emotion. He not only uses it on the characters but on the places and even objects found in the novel. Two example of symbolism and what they truly represent are, The Valley of Ashes and Tom and Daisy’s house. The Valley of Ashes was first introduced in Chapter II, its located between West Egg and New York City, it consists of a long stretch of desolate land created by the dumping of industrial ashes. It represents the moral and social decay that results from being part of the lower class, as the rich only worry for their pleasures. The Valley of Ashes also symbolizes the unfortunate conditions of the lower class, like George and Myrtle Wilson, who live among the dirty ashes and lose their durability as a result. In other words, The Valley of ashes can also be referred to as â€Å"the symbol of failure of the American dream†. Tom and Daisy’s house is a fairly large and well elaborated colonial mansion, located on East Egg, the rich and prestigious side where only the people who are â€Å"truly rich† live, not the ones that have made their fortunes themselves. Tom and Daisy’s house is spacious, just like their marriage, but it has nice furniture and antiques so that it appears to be comfortable and old fashioned, and anyone would assume that a happy family lives in it. Tom and Daisy, like the house, are not really happy, or in love, but they have all the right properties and conveniences to cover up the real situation, their huge marital problems. Fitzgerald’s description of Tom Buchanan’s huge house not only symbolizes his marriage but Tom and his values. The red and white colors in the mansion represent his personality. Red in this case is an example of impurity and boldness, while white represents Tom’s superiority towards others. This huge house represents nothing but Tom and Daisy’s marital problems and Tom’s arrogant attitude. This two places and its inhabitants at first glance appear to be very

Social Media and the Egyptian Revolution

January 2011 marked the beginning of peaceful protests and movement demonstrations staged by citizens throughout Egypt. Movement actors fought for democratic advances, political freedoms and equality. The genuine commitment for change, the unity of the people and most notably the tactful com/the-effects-of-social-media-on-communication-skills/">manipulation of social media resulted in the disposition of the suppressive regime. Modern social media has significantly changed the traditional forms of activism and has simplified the efforts needed to provoke civic mobilization.Social media applications such as Twitter, Facebook and YouTube hold the dynamic power to manipulate, control, inform and motivate. Essentially, they have become excellent tools for activists. This paper seeks to describe and assess specifically the relationship between social media and the Egyptian Revolution. Building on this foundation, this essay will prove that social media platforms were the major catalysts fo r social change in Egypt. To begin, social media, or more precisely Twitter and Facebook, defined and formed the movement's collective identity.These platforms represented safe environments that permitted individuals to consult about common grievances and share revolutionary ideas (Comunello & Anzera, 2012; 466). Furthermore, social media applications played key roles in facilitating the efforts needed for communication, organization, and recruitment (ibid). These applications were highly trusted as they allowed activists to network effortlessly and moreover, assisted in turning rational individuals into constituents. Lastly, social media aided in attracting global support and ‘helped spread democratic ideas across international borders' (Comunello & Anzera, 2012; 466).By referencing the works of scholars such as Kenneth Pollack, Halim Rane and Francesca Communello, this paper will prove social media as the underlying force of the Egyptian revolution. To begin, the con versations held on Facebook and Twitter shaped the collective identity that would make ‘individuals feel capable of effecting change' (Staggenborg, 2008; 191). Twitter and Facebook were the underlying catalytic forces of the movement as they provided a space that would allow Egyptians to publically aspire for changes and ‘express opposition to the existing order' (Doran, 2011; 41).â€Å"We Are All Khaled Said† was a Facebook page that established Khaled Said's death as the spark of the Egyptian movement. With Said's brutally beaten face as the banner, this page quickly spurred anger as it emphasized both the unreasonable level of cruelty that was exerted towards him and as well as the oppression Egyptians faced daily. Remarkably over the course of a few weeks, half a million Egyptians were on Facebook, expressing their anger and sharing their grievances over police brutality, rising food prices and corruption.This platform page assisted in framing the movement â⠂¬Å"in terms of demands for dignity, justice, freedom and democracy† (Rane et al, 2012; 80). The establishment of the movement's frame gave rise to many other Facebook pages. These highlighted the corrupted practices of the government and educated both constituents and adherents to the movement about democracy and its benefits. Facebook succeeded in breaking down the psychological fear barrier that obstructed Egyptians from participating.Once fear was no longer an issue, the Egyptian social capital progressed intensively as the collective consciousness emerged. Facebook was used as a mobilization structure that would undeniably give back the power to the people and restore their self esteem. Correspondingly, Tunisia's success in toppling their dictator, had inspired a wave of revolutions in the Middle-East. Socio-political debates and ideas of democratic advances in Egypt were highly influenced by the current events in Tunisia. These influences had left a marginal impact on th e Egyptian collective identity.By using social media platforms, Tunisian activists guided their Egyptian counterparts regarding the matters of revolution. On Facebook, Tunisians inspired Egyptians by further highlighting the benefits of democratic advancements and by providing words of encouragement and advice ( Rane & Salem, 2012; 85). Tunisians contributed to the empowerment and collective morale of the Egyptian people entirely through the use of social networking applications. Social media is what ultimately allowed the Egyptian people to be galvanized.It created a type of common room that allowed dissidents to speak feely which gave emergence to the movements collective action frame and identity. As Twitter and Facebook were deduced as safe and anonymous environments, the psychological fear barrier had eventually been broken, thus supporting the thesis that social media was undeniably a prominent feature in the outcome in Egypt. (Rane & Salem, 2012; 84) In addition, Twit ter and Facebook had facilitated the movement's needed efforts for mobilization.Activists used these platforms as reliable tools  to propagate their message and contact fellow movement actors. Both Twitter and Facebook contain features that allow statements to be liked, shared or quoted; therefore breaking down all geographical barriers. Egyptian activists, while by passing government restrictions, would use these applications to strategically organize peaceful protests and other forms of collective activities and events. Movement actors would organize ways to contest authorities on Twitter or Facebook as they knew their great power to spread news (Idle and Nunns, 2011, p. 20).Specifically, Twitter played a key role during the revolution as it held the power to potentially turn a simple tweet into a worldwide trending topic. Similarly to the diffusion theory, Twitter along with Facebook became key channels of diffusion. Both these applications accelerated the speed at which the ad opters received the innovations initiated by the transmitters, resulting in the instantaneous mobilization of individuals and resources ( Rane & Salem, 2012; 78). The pertinent example of this phenomenon presents itself a few days prior to the massive revolutionary demonstrations of January 25.To avoid attracting authorities, main organizers of this uprising had avoided disclosing details too early. When details were finally shared, it diffused virally over social media applications at an impeccable speed that would attract 80, 000 protestors in two days, thus proving social media as a prominent inciting force. Social media was used to raise expectations of success and coordinate strategy (Howard et al. 2011; 9). These networks were manipulated in ways that would inspire â€Å"dissidents to organize protests, criticize their governments and spread ideas about democracy† (ibid).Twitter and Facebook supported Egyptian activists by sustaining collective action and by facilit ating the process of diffusion (Rane & Salem, 2012; 90). To deduce, social media simplified the dynamics needed to provoke the mobilization of the Egyptian social movement, thus supporting the thesis that Twitter and Facebook were the catalysts to the movement. Lastly, social media platforms galvanized foreign support and â€Å"helped to globally spread voices against [oppressive] regimes† factors that contributed to the movement's success (Comunello & Anzera, 2012; 466).As previously mentioned, social media networks had broken down the geographical barriers that would otherwise limit activists. Twitter, Facebook and YouTube disseminated images and videos of police brutality towards the relatively peaceful protestors; which heightened awareness in countries. Activists used these platforms in their favour to gain international support, thus weakening the oppressive regime. Simply put, the more Egyptians attracted awareness, the more likely Mubarak would fall.Specifical ly, Egyptians directed these images to Western countries as they recognized that added pressures from these States was paramount (Khamis & Vaughn, 2011). An important speech permitted Egyptian movement actors had known of their success days before Mubarak had actually resigned. When Obama publically stated his discontentment with the Egyptian government's abuse of power, there was a cry of victory in all of Egypt. The Leader of the Free World's statement had rekindled the fire of passion and had empowered Egyptians, inspiring them to continue their pursue for change.Moreover, similarly to the Tunisian Revolution, the Egyptian Revolution had sparked movements throughout the Middle East. Countries across the Middle East and North Africa (MENA) region share many common elements, thus explaining the wave of uprisings (Rane & Salem, 2012; 84). The Egyptian movement was merely a response to a lack of human rights and freedoms and its success, motivated all pro- democratic activist s in the MENA region. These activists learned of the power of social media by following the Egyptian movement on Twitter and Facebook.In hoping to rid their countries from â€Å"adverse social, economic and political situation†, activists look at social media platforms as the initiators for change (ibid).. Consequently, current oppressive governments in the Middle East have taken example from the failures of the Egyptian and Tunisian governments and â€Å"have been subjected to a new level of scrutiny† (Doran, 2011; 43). In Syria, the authoritative government has been behaving with great brutality in response to mobilization efforts. Assad has ruthlessly killed many of the rioting individuals all while censoring the media, in efforts of shielding ‘himself from foreign audit' (ibid).The social media tactics used by Egyptian and Tunisian activists have weakened their respective government all while strengthening other authoritarian governments in the region. Twitte r and Facebook supported Egypt during its plight for social change as they assisted activists in raising international awareness. Because of their abilities to cascade information virally with no geographical limits, the Egyptian Revolution became an international topic in a matter of weeks; ultimately leading to the movements success.Lastly, social media aided with  spreading ideas of revolution and democracy in the MENA region (Rane & Salem, 2012; 84). The diffusion of Egypt's success on Facebook and Twitter, inspired pro-democratic movements throughout the Middle East; thus supporting the statement that social media was the seminal impulse for social change in Egypt and as well as the rest of the Middle East. â€Å"The best practical reason to think that social media can help bring political change is that both dissidents and governments think they can† C. Shirky ( Comunello & Anzera, 2012; 461).The Egyptian Revolution and the contributory role played by Twitter and Facebook demonstrate the predominant effect social media platforms have on social movements. The achievement of the movements objectives didn't solely depend on social media; offline efforts were required. Nevertheless, Twitter and Facebook were the major driving forces of the movement as they accelerated the movement's progression towards success. To begin, these social media applications shaped the collective action frame and defined the collective identity, ultimately leading to the mobilization of the movement.Furthermore, these platforms facilitated communicational efforts and the transfer of pertinent information thus simplifying all the dynamics involved with mobilization. Lastly, Twitter and Facebook helped in the spreading of democratic ideas and attracted the international awareness needed that would essentially overthrow the Mubarak regime. Considering these statements aforementioned, it is extremely likely that without these social media platforms, the revolution wou ld have evolved at a much slower pace, therefore proving that these platforms were verily major catalysts for social change in Egypt.

NATURE OF SCIENCE Definition: Science can be defined as study â€Å"mainly concerned with the phenomenon of physical universe any or all of natural sciences or biological sciences. Or Science as the â€Å"the field of study which attempts to describe and understand the nature of the universe in whole or part. † Science is the faculty to reason out the how and why of the things as they occur in the phenomenal world or t he objective world†¦ Basically science is the study of laws of nature and man has developed science by observing. Infact this subject has completely transformed our power over nature and the world outlook. Development of the modern technology is directly the outcome of the development of modern science.Without the scientific revolution the industrial revolution would not have been possible. It has raised the human activity level by significant observations in the various fields of human existence. Whether it‘s the exploration of human health, industrial progress, agrarian developments and modern communication technologies, the benefits gained from this major subject are enormous. Infact it would not be wrong to say that we are living in the age of science and is a dominant factor in our day to day existence. 2.

This hidden potential is surfaced out by the subject of science through the process of understanding. Science has proved to be of enormous beneficial nature . It h as made lasting impact on regarding each and every field of human existence. Whether it is concerned with our day to day lives or whether it is related with the various modern developments which have resulted in elevating the living standards of the individuals.The significant contributions which the study of this subject has made are enumerated below. SCIENCE AND HUMAN ATTITUDE: The various noteworthy scientific advances have helped the individuals in raising up of their self confidence . This subject has enabled the human beings to control and modify their needs and requriements. With greater understanding of the scientific phenomena human beings have now become more confident about the environmental issues as compared to the people in the past. Infact science has promoted and paved the way for the independent and logical thinking.SCIENCE AND HUMAN HEALTH: Before the development of modern medicinal factors, a large number of people used to lose their precious lives because of the unavailability of the sources and medicines for a proper health care. With the advancements of science now the human life expectancy rate has increased as the various modern developments in the field of health care has helped in warding off the dangerous diseases†¦ The revolutions in surgery and medicine the infectious diseases like small pox, malaria, typhoid etc. have been eradicated. Thus science has improved the health standards of the people. SCIENCE AND TRAVEL: People used to travel on foot before the inventions of automobiles,aeroplanes and steam engines. They also used animal carts and camels for the purpose of moving from one place to another. However, the modern scientific inventions have proved to be of great significance as it has added speed to the area of travel. The quick means of transportation have decreased the distances and are a source of saving time. In fact it would not be wrong to regard that these inventions have added much peace to the lives of the mode rn men.SCIENCE AND COMMUNICATION: Science has also played a significant part in the development of the modern communication technology. Earlier people were living in isolation because of the slow means of communication. Now the well developed, efficient media have made it possible to communicate with each other more rapidly and quickly. The impact of mass media is enormous. The use of computers and televisions has made the world a global village where an event in one part of the world leaves an influence on the other.DEMERITS OF SCIENCE: Every invention of science has got its own merits and demerits. The most serious invention that science has contributed to is the development of the weapons of mass destruction like the atom and nuclear bombs. The recent wars have greatly showed that how much destruction can be brought about with the use of these lethal weapons. In fact these modern inventions of science have resulted in the elevation of the anxiety and unrest in the modern societie s. Another notable demerit which the study of this subject has lead to the rise in the environmental deterioration.Day by day the pollution factor is increasing which has proved to be very toxic and harmful for the human health. Not only the human health it is also proving fatal for the animals as well as the existing plants. The rapid developments of science and industrialization have also divided the world. The developed and the undeveloped. This division has lead to a widening gap between the status and the living standards of people. There is economic disparity which has also given rise to class distinction 4. UNIVERSEThe BIG BANG THEORY about the universe is the most widely acceptable theories with regard to the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions. All the galaxies were formed from this matter. Observations of these galaxi es show that they are still moving apart from each other . The universe is expanding Some scientists have suggested another theory as â€Å"steady theory:† to explain the process of the evolution of the universe.However the general notion on which all scientists agree is the theory of Big Bang. Steady theory is the theory about the universe and the observations by the astronomers have shown that the galaxies are moving away from each other and the universe seems to be expanding. The theory shows that the new matter is always being created to fill the space left by this expansion. The new matter moves apart and forms galaxies which continue to move apart. This means that the universe always look exactly the same. It has no beginning or end but in a steady state.However many observations have suggested that the universe has not always looked like the same. THE FUTURE OF UNIVERSE: At present the universe is expanding but the astronomers have questioned that whether or not this e xpansion will continue . Certain observations which have been made in this regard is that one possible ending of the universe will be the â€Å"big crunch?. The galaxies and other matter may be moving apart but their motion is restrained by their mutual gravitational attraction. If there is a sufficient matter in the universe gravity will eventually win and egin pulling the galaxies together again causing the universe to experience a reverse of the big bang i. e. , the BIG CRUNCH. However there is a possibility that there is not enough matter in the universe for the big crunch to happen. This means that if it happens then the universe will continue to expand forever. 5. GALAXY Galaxy is a huge number of stars grouped together. The term galaxy can also be described as a collection of dust, gas and stars measuring thousands of parsecs across. Galzxy contains 10000million stars and looks like a disc with a fat centre and spiral arms.From the front it looks like a convex lens‘s C lasses of galaxy: Two broad classes of galaxy are there. 1. Elliptical 2. Spiral the spiral galaxies are further sub divided into normal which constitutes of majority of spirals and barred spirals. Barred spirals have their centre in the form of the bar. The elliptical galaxies range from E 0 to E 7 from an almost spherical shape to a flattened disc. 5 Milky Way: Our galaxy is a spiral galaxy about 30,000 parsecs across. There are more than 200 billion stars in the galaxy.Its disc appears as a faint white band that is responsible for dividing the white sky at the night into two. The name of our galaxy is Milky Way. The galaxy has three spiral arms called the Orion, Perseus, and Sagittarius arms and the whole system is rotating in space. The sun revolves around the nucleus of the galaxy once in 225 million years. This duration is also called the cosmic year. I -INTRODUCTION: Milky Way, the large, disk-shaped aggregation of stars, or galaxy, that includes the Sun and its solar system. In addition to the Sun, the Milky Way contains about 400 billion other stars.There are hundreds of billions of other galaxies in the universe, some of which are much larger and contain many more stars than the Milky Way. The Milky Way is visible at night, appearing as a faintly luminous band that stretches across the sky. The name Milky Way is derived from Greek mythology, in which the band of light was said to be milk from the breast of the goddess Hera. Its hazy appearance results from the combined light of stars too far away to be distinguished individually by the unaided eye. All of the individual stars that are distinct in the sky lie within the Milky Way Galaxy.From the middle northern latitudes, the Milky Way is best seen on clear, moonless, summer nights, when it appears as a luminous, irregular band circling the sky from the northeastern to the southeastern horizon. It extends through the constellations Peruses, Cassiopeia, and Cepheus. In the region of the Northern Cross it divides into two streams: the western stream, which is bright as it passes through the Northern Cross, fades near Ophiuchus, or the Serpent Bearer, because of dense dust clouds, and appears again in Scorpio; and the eastern stream, which grows brighter as it passes southward through Sputum and Sagittarius.The brightest part of the Milky Way extends from Sputum to Scorpio, through Sagittarius. The center of the galaxy lies in the direction of Sagittarius and is about 25,000 light-years from the Sun (a light-year is the distance light travels in a year, about 9. 46 trillion km or 5. 88 trillion mi). II -STRUCTURE: Galaxies have three common shapes: elliptical, spiral, and irregular. Elliptical galaxies have an ovoid or globular shape and generally contain older stars. Spiral galaxies are disk-shaped with arms that curve around their edges, making these galaxies look like whirlpools.Spiral galaxies contain both old and young stars as well as numerous clouds of dust and gas from whic h new stars are born. Irregular galaxies have no regular structure. Astronomers believe that their structures were distorted by collisions with other galaxies. Astronomers classify the Milky Way as a large spiral or possibly a barred spiral galaxy, with several spiral arms coiling around a central bulge about 10,000 light-years thick. Stars in the central bulge are close together, while those in the arms are farther apart. The arms also contain clouds of interstellar dust and gas.The disk is about 100,000 light-years in diameter and is surrounded by a larger cloud of hydrogen gas. Surrounding this cloud in turn is a spherical halo that contains many separate globular clusters of stars mainly lying above or below the disk. This halo may be more than twice as wide as the disk itself. In addition, studies of galactic movements suggest that the Milky Way system contains far more matter than is accounted for by the visible disk and attendant clusters—up to 2,000 billion times more mass than the Sun contains.Astronomers have therefore speculated that the known Milky Way system is in turn surrounded by a much larger ring or halo of undetected matter known as dark matter. III -TYPES OF STARS: The Milky Way contains both the so-called type I stars, brilliant, blue stars; and type II stars, giant red stars. Blue stars tend to be younger because they burn furiously and use up all of their fuel within a few tens of millions of years. Red stars are usually older, and use their fuel at a slower rate that they can sustain for tens of billions of years.The central Milky Way and the halo are largely composed of the type II population. Most of this region is obscured behind dust clouds, which prevent visual observation. Astronomers have been able to detect light from this region at other wavelengths in the electromagnetic spectrum, however, using radio and infrared telescopes and satellites that detect X rays (see Radio Astronomy; Infrared Astronomy; X-Ray Astronomy). Su ch studies indicate compact objects near the galactic center, probably a massive black hole. A black hole is an object so dense that nothing, not even light, can escape its intense gravity.The center of the galaxy is home to clouds of antimatter particles, which reveal themselves by emitting gamma rays when they meet particles of matter and annihilate. Astronomers believe the antimatter particles provide more evidence for a massive black hole at the Milky Way‘s center. Observations of stars racing around the center also suggest the presence of a black hole. The stars orbit at speeds up to 1. 8 million km/h (1. 1 million mph)—17 times the speed at which Earth circles the Sun—even though they are hundreds of times farther from the center than Earth is from the Sun.The greater an object‘s mass, the faster an object orbiting it at a given distance will move. Whatever lies at the center of the galaxy must have a tremendous amount of mass packed into a relatively small area in order to cause these stars to orbit so quickly at such a distance. The most likely candidate is a black hole. Surrounding the central region is a fairly flat disk comprising stars of both type II and type I; the brightest members of the latter category are luminous, blue supergiant.Imbedded in the disk, and emerging from opposite sides of the central region, are the spiral arms, which contain a majority of the type I population together with much interstellar dust and gas. One arm passes in the vicinity of the Sun and includes the great nebula in Orion. See Nebula. 6 IV -ROTATION: The Milky Way rotates around an axis joining the galactic poles. Viewed from the north galactic pole, the rotation of the Milky Way is clockwise, and the spiral arms trail in the same direction. The period of rotation decreases with the distance from the center of the galactic system.In the neighborhood of the solar system the period of rotation is more than 200 million years. The speed of t he solar system due to the galactic rotation is about 220 km/sec (about 140 mi/sec). 6. SOLAR SYSTEM The solar system includes nine planets and sun being at the centre. All the planets revolve around the sun . The solar system also includes the asteroids, meteors and numerous comets. All of these travel around the sun in a particular orbit . The planets which are the significant part of the solar system namely,Mercury,venus,earth,mars,Jupiter,Saturn
