Ghost Light from Dead Galaxies Sheds Light on Ancient Galaxy Interactions

Did you know that astronomers can learn about galaxies that died long ago? Thats part of the story of the cosmos that the  deep cosmos-gazing  Hubble Space Telescope  was built to tell. Along with other telescopes on the ground and on orbit, it fills in the story of the universe as it peers out at distant objects. Some of its most fascinating objects are galaxies, including some that formed in the infancy of the universe and are now long gone from the cosmic scene. What stories do they tell?   What Hubble Found Studying long-dead galaxies sounds like it would be impossible. In a way, it is. Theyre no longer around, but it turns out, some of their stars are. To learn more about early galaxies that no longer exist, Hubble observed dim  light from orphaned stars that lie some 4 billion light-years away from us. They were born billions of years ago and somehow were ejected at high speed from their original galaxies, which themselves are long gone. It turns out some kind of galactic mayhem sent these stars reeling across space. They belonged to a galaxies in a massive galaxy called Pandoras Cluster. The light from those far-flung stars provided clues to a crime scene of truly galactic proportions: as many as six galaxies were somehow torn to pieces within the cluster. How could this happen? Gravity Explains a Lot Each galaxy has a gravitational pull. Its the combined gravity of all the stars, clouds of gas and dust, black holes, and dark matter that exist in the galaxy.  In a cluster, you get the combined gravitational pull of all the galaxies, and that affects all of the members of the cluster. That gravity is pretty strong. In addition, galaxies tend to move around within their clusters, which affects the motions and interacts of their cluster-mates. Add those two effects together and you set the scene  for the destruction of some not-so-lucky small galaxies that happen to get caught in the action.  They get stuck in a squeeze play between their larger neighbors as they travel, Eventually, the strong gravity of the bigger galaxies pulls the smaller ones apart.   Astronomers found clues to this destructive shredding of galaxies by studying the light from stars scattered by the action.That light would be detectable long after the galaxies were destroyed. However, this predicted intracluster glow of stars is very faint and is quite a challenge to observe.These are extremely faint stars and they are brightest in infrared wavelengths of light. This is where Hubble comes in. It has very sensitive detectors to capture that faint glow from the stars. Its observations helped scientists study the combined light of about 200 billion stars that were cast out from interacting galaxies. Its measurements showed that the scattered stars are rich in heavier elements like oxygen, carbon, and nitrogen. This means they are not the first-ever stars formed. The first stars consisted mainly of hydrogen and helium, and forged heavier elements in their cores. When those earliest ones died, all the elements were cast into space and into nebulae of gas and dust. Later generations of stars formed from those clouds and show higher concentrations of heavy elements. It is the enriched stars that Hubble studied in an effort to track what happened to their galactic homes.   Future Studies Zero in on More Orphan Stars Theres still a lot to figure out about the earliest, most distant galaxies and their interactions. Everywhere Hubble looks, it finds more and more distant galaxies. The farther out it  peers, the further back in time it looks. Each time it makes a deep field observation, this telescope shows astronomers fascinating things about the earliest times in the cosmos. Thats all part of the study of cosmology, the origin and evolution of the universe.

Mulan Free Essays

Hayden Ikerd Mr. Wheeler AP Literature 12 April, 2013 Thomas Foster’s Themes Traced in Mulan In his book How to Read Literature Like a Professor, Thomas Foster explains many reoccurring themes in literature, and shows how to recognize them and in some instances shows certain works where they occur. By reading this guide to literature, one may gain a deeper understanding of the work itself and of the author’s intent in writing it. We will write a custom essay sample on Mulan or any similar topic only for you Order Now However, Foster’s methods can also be applied to films. A film that contains many of the various themes, models, symbolism, and devices discussed in his book is Walt Disney’s Mulan. Mulan is a character type with which people are familiar. Foster discusses this process of association in the chapter â€Å"Now Where Have I Seen Her Before? † In his book, he asserts that no work is wholly original. The whole idea of a female Chinese heroine was not originally conceived by Disney. The character of Mulan can be traced back to The Ballad of Hua Mulan, written sometime in the 11th century. Still, most people may not be so familiar with this relatively dated ballad. Some people may associate the character of Mulan with that of Scout from To Kill a Mockingbird. Both Mulan and Scout are tomboys by nature, acting in ways more suited to boys. Also, they both do things they do for the approval of their respective father figures. Mulan is notably the heroine of her story, saving the Chinese empire from the attacking Huns. The ‘heroine’ model can also be seen in characters such as Antigone and Hester Prynne. Food plays some role in every work- namely the act of consuming it. Mulan is no exception. Foster talks about this in the chapter â€Å"Nice To Eat With You. † Towards the beginning of the movie, Mulan along with several other young maidens go to visit the match maker, who is in charge of determining each girl’s eligibility as a wife. This process by which she judges them is by partaking in a cup of tea with each one. Mulan’s ‘interview’ as it were went over horribly. This is to establish the fact that Mulan has a measure of difficulty coming into womanhood, and the whole idea of being ladylike does not come to her naturally. The second meal that plays a big part in the film is the one that takes place in the barracks. Mulan just met her fellow soldiers, and the next thing to occur is a meal with them. Trying to establish herself as a man, she accidently picks a fight with one, leading to a riot, and rice being spilled all over the camp. After this, they all held her in contempt. Mulan’s first meal with her comrades shows that she has just as hard a time fitting in with these men as she did with the women. Mulan’s two meals show the difficulty she has trying to find her place. The role of men and women play an important role in this movie. Foster touches this phenomenon in the chapter â€Å"It’s All Political. † The underlying message of Mulan is that of gender equality. As a woman, Mulan is looked down upon, and is not allowed to fight in the war against the Huns in the first place. To fight is to disgrace her whole family. This offense was so dire, that when she was discovered to be a woman on the battlefield, she was sentenced to death. She is also portrayed as being weaker and less capable than the other soldiers. However, she learns to keep up, and eventually excels in combat training and proves to be an invaluable asset to the Chinese army. In the end, Mulan portrays women as strong, and in the battle could not have been won without femininity. Towards the end, the Huns are ultimately overcome by the male soldiers dressing as women, who seduce them, then defeat them. In the end of the film, virtually all of China bows to Mulan in respect, showing that she is held in equal esteem as even the emperor, who is male (he also bows, of course). Another important element in Mulan that Foster points out is that of rain, which he mentions in his chapter entitled, â€Å"It’s More Than Just Rain or Snow. † Foster would have one to believe that often times when a character goes through rain, snow, or something of the sort, that he or she has undergone a figurative baptism. After Mulan has failed in her encounter with the matchmaker, she goes home and begins singing the marvelous, gripping song called â€Å"Reflection†. She asks, â€Å"When will my reflection show who I am inside? She realizes that her fair appearance does not reflect her feelings. Singing this song, she washes away her makeup, and gives up on becoming the perfect daughter and bride; it is a baptism. Maybe it would be key to mention that during this song, Mulan sings in a downpour of rain. Just like Foster describes in his book, Mulan is ‘baptized’ in the rain. Disney movies are not notorious for their violent nature. So, when so mething violent occurs in a Disney movie, or an individual (or animal in many cases) dies, it must carry some kind of importance. In the chapter of his book â€Å"More Than It’s Gonna Hurt You†, Fosters says that there is usually more to violence than just violence. When Mulan is struck by the sword of Shan Yu, many more things happen to her than a fatal wound. She almost meets her demise, and for the first time, the reality of war sets in. Mulan realizes that she is not invincible and grasps the perils of war for the first time. When she receives medical attention for her wound, she is discovered to be a woman. All she has worked for up until this point is now for naught, as she is expelled from the army and her family name is disgraced. Another instance where violence plays an important role is when Li Shang’s father is discovered to be dead. Li Shang’s father was the head general of the Chinese army; he was held in high esteem by everyone, especially his son. Li Shang aspired to be the general his father was. Shang’s father’s plan was to make an assault on the Hun army, and meet up with Shang after they had obtained victory, which they thought was inevitable. When Shang reaches the point at which he was to intersect with his father, he found him gone. Shang’s father’s death signals the time for Shang to take up the burden of leading the Chinese army and the time to become a man. The only way for China to be victorious was for Shang to surpass his father and to do what he could not: defeat the Huns. Without this loss, Shang would have never grown and would have never become the general that he was. One can see that Foster’s themes are very prevalent in the story of Mulan and are echoed in movies and books alike. Mulan is a real masterpiece to include so many elements of good literature.

Robert Browning Essays (448 words) - Robert Browning,

Robert Browning B.J. Gilstrap English March 20, 1999 Biography of Robert Browning Robert Browning was born on May 7, 1812, in Camberwell (a suburb of London), the first child of Robert and Sarah Anna Browning. His mother was a fervent and an accomplished pianist. Mr. Browning had angered his own father and forgone a fortune: the poet's grandfather had sent his son to oversee a West Indies sugar plantation, but the young man had found the institution of slavery so abhorrent that he gave up his prospects and returned home, to become a clerk in the Bank of England. On this very modest salary he was able to marry, raise a family, and to acquire a library of 6000 volumes. He was an exceedingly well-read man who could recreate the siege of Troy with the household chairs and tables for the benefit of his inquisitive son. Indeed, most of the poet's education came at home. He was an extremely bright child and a voracious reader and learned Latin, Greek, French and Italian by the time he was fourteen. He attended the University of London in 1828, the first year it opened, but left in discontent to pursue his own reading at his own pace. This somewhat distinctive but extensive education has led to difficulties for his readers: he did not always realize how obscure were his references and allusions. In 1845 he saw Elizabeth Barrett's poems and contrived to meet her. Although she was an invalid and very much under the control of a domineering father, the two married in September 1846 and a few days later eloped to Italy, where they lived until her death in 1861. The years in Florence were among the happiest for both of them. Her love for him was demonstrated in the Sonnets from the Portugese, and to her he dedicated Men and Women, which contains his best poetry. Public sympathy for him after her death (she was a much more popular poet during their lifetimes) surely helped the critical reception of his Collected Poems (1862) and Dramatis Personae (1863). The Ring and the Book (1868-9), based on an old yellow book which told of a Roman murder and trial, finally won him considerable popularity. He and Tennyson were now mentioned together as the foremost poets of the age. Although he lived and wrote actively for another twenty years, the late '60s were the peak of his career. His inf luence continued to grow, however, and finally lead to the founding of the Browning Society in 1881. He died in 1889, on the same day that his final volume of verse, Asolando, was published. He is buried in Poet's Corner of Westminster Abbey. Poetry Essays

An Overview of the Branches of Philosophy essays

An Overview of the Branches of Philosophy essays Generally speaking, philosophy the critical examination of the grounds for fundamental beliefs and an analysis of the basic concepts employed in the expression of such beliefs. Philosophical inquiry is a central element in the intellectual history of many historical civilizations. The word is from the Greek (by way of Latin, philosophia) and means "love of wisdom" (Martinich provides a brief definition and description of three approaches to philosophical investigation: metaphysics, epistemology, and axiology (including its two branches, aesthetics and ethics). Metaphysics. This branch of philosophy deals with the ultimate nature of human existence, largely as an extension of the Metaphysics of Aristotle. This collection of treatises placed after the Physics [Gr. metaphysics =after physics ] treated what Aristotle termed the First Philosophy. The primary focus of metaphysical speculation is termed "ontology," which is the study of the ultimate nature of being; however, philosophical theology and cosmology are typically considered branches of metaphysics as well (Metaphysics 2000). This branch of philosophy leaves nothing unquestioned and proceeds entirely without assumptions; according to Walsh (1963), "The only propositions with which a metaphysician could properly be content were propositions whose truth could not be denied, or whose truth was seen to be involved in their own attempted denial" (11). Epistemology. This field of philosophy is defined as the study of the nature, origin, and limits of human knowledge. The term comes from the Greek episteme ("knowledge") and logos ("reason"), and accordingly the field is sometimes called the theory of knowledge (Martinich Axiology. This branch of philosophy is concerned with "values" and "what is good" (Morris 1961:219). "If axiological issues underlie ethical ...

Creating Compelling Characters

Creating Compelling Characters Creating Compelling Characters Creating Compelling Characters By Guest Author This is a guest post by Ali Hale. If you want to write for Daily Writing Tips check the guidelines here. The success of a story rests on its characters. We remember truly compelling, vivid characters long after weve finished reading a novel or watching a movie: Im sure you can recall characters from books you read in childhood. Great characters can compensate for a weak plot or a so-so writing style – but if readers dont care about your characters, theyll put your story down. That clever plot twist or beautiful passage of writing might hook them briefly, but without characters that leap off the page, readers wont stay engaged. If you need more evidence that characters are crucially important, search Google for fan fiction. Many, many books, TV series and movies have spawned a huge amount of creative writing by fans – and this writing is all about the characters. The plots and sometimes even the settings are different from those in the original, but the characters remain the same. Simply knowing how important characters are doesnt help you much, though. You need to figure out how to create truly compelling characters who readers care about, laugh about, even cry about. Heres how: What Does Your Character Need? All compelling characters have a strong need, longing or desire. They should have a problem to overcome. They may not recognise this need (and indeed, many stories are about person coming to understand themselves better – for example, learning that they need companionship). I picked up a great tip on figuring out what characters need from Holly Lisles Create a Character Clinic. Use Maslows hierarchy of needs. Pick a level on the pyramid (you can find all you need to know on Wikipedias page) and then figure out what your character is seeking. At the most basic, physical level, your character might be in a survival situation and need food and water. Going up a level, you might have a character whose security is threatened: perhaps shes lost her job, or hes facing a health crisis. Quirks Dont Equal Character Many beginning writers make the mistake of thinking that giving a character a set of mannerisms or physical quirks is characterisation. It can be amusing and diverting, certainly. Sure, you can give your character a habit of whistling a particular tune, or jangling his keys, or peering over her glasses. But these alone dont make your characters compelling. When your characters do have unusual quirks, these need to be relevant to their back story – the things which happened to them before they appeared in your book. (Compelling characters need to be like icebergs: the reader has to have the sense that theres a lot more under the surface: characters shouldnt feel like they didnt exist before page one.) For example, Harry Potters scar is an important feature because it relates to his history and to the broader plot of the stories. Giving your character a mysterious scar which has no relevance to your story, however, isnt a shortcut to becoming as popular as J.K. Rowling In general, focus on who your character is rather than what they look like. Draw From Life – But Not Too Much So where do powerful, vivid characters come from? Often, the best place to start is yourself. What do you dream about, fear, desire? What secrets do you have? What are you most ashamed of – and most proud of? If youre trying to convey a characters internal thoughts, then you must be willing to draw on your only source of direct experience: the inside of your own mind. Dont go too far in drawing on real life, though. Beginning writers sometimes make the mistake of writing a version of themselves into their stories – often a perfect, flawless character who theyd quite like to be! While this might be emotionally satisfying to the writer, its either very irritating or very boring for readers. Some other tips when drawing on your life are: Were all complex people who may, at times, behave in contradictory ways. Dont make your characters too one-dimensional Most of us have quiet, even boring, lives. Your characters need to do more exciting things in order to engage the reader. Dont worry about describing your characters physically. Mention anything thats important (eg. a characters physical size may have a bearing on the plot and on their self-confidence) but dont burden the reader with details. Watch people when youre out and about, and make up stories about them. Let the Reader Empathise Your reader doesnt necessarily have to like your characters, but they should be able to feel a sense of empathy for them. Even your villains shouldnt be purely evil: there needs to be some explanation for why theyre such awful people – this often forms part of their back story. On the flip side, your heroes shouldnt be too perfect. We like to read about people with flaws, doubts and struggles – because when we read, were imagining ourselves in their place. Characters are compelling when we can share their struggles and cheer on their victories. Some quick ways to build empathy are: Show a character suffering (either mentally or physically) Include a brief flashback to an unhappy childhood or traumatic incident Write about your characters thoughts – especially if their actions might be hard for us to understand or treat sympathetically Use the first-person or third-person limited (deep) point of view Show a character being misunderstood by others Frustrate a characters attempts to meet their need Finally, have fun with creating your characters! If you find yourself writing about a character who bores you, then rewrite them – or recast them as a new character entirely. When you write characters that are truly compelling to you, theyll be compelling to the reader.

Assignment # 1 - Geography of Everyday Life Essay

Assignment # 1 - Geography of Everyday Life - Essay Example Although people inside the gym are normally few in the mornings, the place normally smells of sweat as people strain and flex their body muscles under various loads. The gym is decorated with pictures of people with a lot of muscle and strength. Whenever I get inside this place, I first feel some temporary tension especially when I think of having to bear the load of weights I will lift. Visiting the gym daily makes me feel more confident about my physical appearance and makes me feel strong, fit and physically powerful. For many people, the gym is a place where one expends some energy to rejuvenate the mind while at the same time strengthening muscles. This is a place where people invest their confidence in to control their Body Mass Index (BMI), blood pressure and boost their muscular endurance. After showering, eating, and spending a little time in the privacy of my home, I walk down to the harbour on a regular basis. The Lakeshore Harbour is a commercial area which welcomes millions of tourists each year, especially in the summertime. It is a huge open area where public events are held daily during the summer, and almost every weekend until extreme weather hits. The interesting thing about the harbour is that it is an extremely busy public area open for anyone, yet it is also the place I like to go when I feel the need for some peace and quiet. The sound of water gently hitting the beach is normally very pleasant to my ears. Although the sound is never pleasant during turbulent weather, the site of the pace is usually captivating during such times. The site of people relaxing, children playing and people rowing in boats or riding on floats is quite delightful to me especially when the sky above is clear. Urban parks, such as the harbour surroundings, are highly valued lan dscapes. They represent sources of pleasure, leisure, and escape from the concrete of the streets, and everyday sensuous encounters with ‘nature’. If

Moral relativism and Moral absolutism Essay Example | Topics and Well Written Essays - 1000 words

Moral relativism and Moral absolutism - Essay Example The concept of moral relativism stipulates that there is no sense in asking abstract questions concerning whether an act is either good or its bad. As per the theory, abstract questions that contain neither goodness nor badness in them. The concept stipulates that the issues of goodness and badness can only be found in contexts that are specified. Therefore, this implies that an action can be good for a certain individual but on the other hand be bad for another individual. It also suggests that certain acts may be correct in a certain cultural setting but considered to be bad in another cultural setting (Moral Relativism. Info). However, if the concept of moral relativism is considered true, an act should not be questioned on its goodness or badness in its abstract form but should only be questioned in particular situations. Different people view the issue of more relativism as being a palpable truth and undeniable whereas others perceive it as a threat to the ethical foundations up on which societies are built (Hammerlinck). The concept of moral relativism has been supported with various proofs by different people. Some of them have put forward arguments from disagreements, flexibility and from tolerance. Those who have forwarded arguments from disagreements argue that ethical relativism best describes the fact that different cultures and individuals have different ethical beliefs. From this perception, the ethical disagreements demonstrate that the issue of morality is just but a product of our personal opinions or our different cultures. This is the exact claim that has been put forward by the notion of moral relativism (Moral Relativism. Info). Other arguments for the notion of moral relativism that have been presented from flexibility arguments stipulate that the issue of moral absolutism will certainly break down when exposed to particular situations.
