Writing Prompts 101

Writing Prompts 101 Writing Prompts 101 Writing Prompts 101 By Simon Kewin Even if you are not a professional writer you probably already heard about writing prompts. They represent a very effective tool for any writing project, so its a good idea to know how to use them. What Is A Writing Prompt? If you’re a fiction writer, you may want to consider using writing prompts to kick-start your creativity. A writing prompt is simply a topic around which you start jotting down ideas. The prompt could be a single word, a short phrase, a complete paragraph or even a picture, with the idea being to give you something to focus upon as you write. You may stick very closely to the original prompt or you may wander off at a tangent. You may just come up with rough, disjointed notes or you may end up with something more polished and complete, a scene or even a complete story. The point is to simply start writing without being held back by any inhibitions or doubts. Here are four good reasons for writing to prompts : Sometimes it’s hard to start writing when faced with a blank page. Focusing on an unrelated prompt for a while helps get the creative juices flowing. If you write for just ten minutes on a prompt, you should then find it easier to return to the piece you intended to write. You may also find that if you stop trying to think so hard about what you wanted to write and switch you attention to the prompt instead, the words and ideas for your original piece start to come to you after all. The things you write in response to a prompt may also end up as worthwhile material in their own right. The prompt may give you ideas from which a complete story grows or you may get fresh ideas for another piece you are already working on. It’s often surprising how much material you come up with once you start. Writing to a prompt regularly helps to get you into the habit of writing. This can act as a sort of exercise regime, helping to build up your â€Å"muscles† so that you start to find it easier and easier to write for longer and longer. Prompts can be a great way to get involved in a writing community. Sometimes writing groups offer a prompt for everyone to write about, with the intention being for everyone to come up with something they can then share. This can be a source of great encouragement, although knowing that others will read what you have written can also inhibit your creativity. Examples of Writing Prompts The following are twenty writing prompts that you could use to spark your imagination. If you want to use one, don’t worry about where the ideas take you or whether what you’ve written is â€Å"good†. The point is just to get into the flow of writing. You can come back later and polish if you wish to. It was the first snowfall of the year. He hadn’t seen her since the day they left High School. The city burned, fire lighting up the night sky. Silk. She studied her face in the mirror. The smell of freshly-cut grass. They came back every year to lay flowers at the spot. The streets were deserted. Where was everyone? Where had they all gone? This time her boss had gone too far. Red eyes. Stars blazed in the night sky. He woke to birdsong. ‘Shh! Hear that?’ ‘I didn’t hear anything.’ He’d always hated speaking in public. She woke, shivering, in the dark of the night. The garden was overgrown now. He’d never noticed a door there before. She’d have to hitch a ride home. ‘I told him not to come back too!’ His feet were already numb. He should have listened. Where To Find Writing Prompts Online The internet is a wonderful source of writing prompts. There are sites dedicated to providing them which a quick search will turn up. Examples include : CreativeWritingPrompts.com WritersDigest.com Creative-Writing-Solutions.com Perhaps even more valuable are the lists compiled by authors and websites. Here are some suggestions: 200+ Writing Prompts to Inspire You There are numerous blogs that offer a regular writing prompt to inspire you and where you can, if you wish, post what you’ve written. Examples include : SundayScribblings.blogspot.com DragonWritingPrompts.blogspot.com There are also many other sites that can, inadvertently, provide a rich seam of material for writing prompts – for example news sites with their intriguing headlines or pictorial sites such as Flickr.com that give you access to a vast range of photographs that can prompt your writing. If you’re on Twitter, there are users you can follow to receive a stream of prompts, for example : twitter.com/writingprompt twitter.com/NoTelling twitter.com/writingink Another idea is just to keep an eye on all the tweets being written by people all over the world, some of which can, inadvertently, be used as writing prompts. How To Make Your Own Writing Prompts You can find ideas for writing prompts of your own from all sorts of places : snatches of overheard conversation, headlines, signs, words picked from a book and so on.

Jean-Jacques Rousseau - The Origins and Effects of Inequality Essay

Jean-Jacques Rousseau - The Origins and Effects of Inequality - Essay Example The Dedication to the Republic of Geneva summarized the essence of Rousseau's views in the following statement: "If I had had to make choice of the place of my birth, I should have preferred a society which had an extent proportionate to the limits of the human faculties; in which every person is equal to his occupations, no one should be obliged to commit to others the functions with which he was entrusted; a State, in which all the individuals being well known to one another, and in which the pleasant custom of seeing and knowing one another should make the love of country rather a love of the citizens than of its soil"(Rousseau, 1993, pp.32-33). The Republic of Geneva was perfectly lining with Rousseau's understanding of an ideal state: a moderate democracy occupying an adequate territory, governed mostly by the laws based on traditions with citizens living relatively plain and calm life. The main paradox emphasized by Rousseau is the following: people prescribe laws to other people without proper knowledge about the natural state of human being. However, this natural law did not exist in contemporary European society that "offered a corrupt form of the species and the inequality inherent in its societies should not be taken as a standard for assessing either other cultures or other species" (Moran, 1993, p.140). For Rousseau who believed that human character was "deeply shaped by society" (Divine, 2000, p.291) it seemed impossible to unveil the true nature of humans in the European context where people had been squeezed by unfair laws and customs for centuries. The philosopher argued that the true measure of a man that would not depend upon contemporary laws and customs could be found only in 'natural' places such as African jungles. Rousseau drew strong parallels between the natural state of human beings and the state of animals. Human beings began as animals having no potent mean of communication such as language, and could not convey much of their knowledge and experience to their offspring, lacked foresight and history. These seemingly disadvantageous features gave the natural men one essential benefit: they did not suffer from the fear of death while contemporary humans feared death virtually every moment of their life (Rousseau, 1993, p.52). Rousseau positioned the natural man "at equal distances from the stupidity of brutes and the fatal enlightenment of civil man" (Rousseau, 1993, p.53). For Rousseau the fatality of enlightenment or civilization meant that it deprived man of the natural desire to exploit the potential of his body to full extent making it an instrument in achieving the balance with nature: "The body of a savage man being the only instrument he understands, he uses it for various purposes, of which ours, for want of practice, are incapable: for our industry deprives us of that force and agility" (Rousseau, 1993, p.53). Civilization brought the understanding that cooperation and mutual help would improve the results of labour, and in the process of such cooperation humans came to realize that some men were better hunters, some were better thinkers, some were stronger, etc. The understanding of inequalities between human beings was, in Rousseau’s opinion, the crucial point: â€Å"†¦from the moment one man began to stand in need of the help of another; from the moment it appeared advantageous to any one man to have enough provisions for two, equality disappeared, property was introduced, work became indispensable, and vast forests became smiling fields, which man had to water with the sweat of his brow, and where slavery and misery were soon seen to germinate and grow up with the crops† (Rousseau, 1993, p.74).

Barry Tomatoland Essay Example | Topics and Well Written Essays - 1000 words

Barry Tomatoland - Essay Example A major downside of these industrially grown tomatoes is their lack of taste, as compared to organically grown tomatoes that re provided with the necessary nutrients and care required. Estabrook gives a rather interesting history of the tomato plant, tracing it back to its original habitat in South America, and provides a great difference between the tomatoes produced today in areas as Florida and those that are grown naturally. The use of industrial agriculture to grow these tomatoes has numerous negative effects to the quality of tomatoes produced and especially to the workers who work in those farms. This paper aims to look at two main issues Estabrook highlights facing the tomato industry and possible solutions to help solve them. Estabrook depicts the state of Florida as the worst state to grow tomatoes given its very poor soils and the high levels of humidity recorded in the state. The tomatoes are grown on sandy soil, which lacks the very important nutrients required for adequ ate growth of most crops, and therefore farmers have to utilize chemical fertilizers in order to make the sand soil a suitable planting medium. The sunny weather and high humidity in the state provide an adequate atmosphere for the existence of many pests and insects such as spots, blights, and molds that pose a serious danger for producing healthy tomatoes. Estabrook explains a disturbing picture of modern-day slavery in one of the most democratic country in the world where people enjoy various rights and freedoms. He clearly shows some of the harsh conditions that most laborers working in these tomato farms undergo, especially in Immokalee, Florida, the major growing area for winter tomatoes. Most of these workers are illegal immigrants, mostly from Mexico, and cannot speak neither Spanish nor English, which places them at a disadvantage. Some of these immigrants are brought into the country through illegal human trafficking channels and are usually tortured and mistreated and sur vive in very poor living conditions, mostly without enough food and proper sanitary facilities. They work very hard and are paid very low wages that are paid irregularly. It is very disturbing to imagine a worker

Case in motivation and teamwork of Starbuck Essay Example for Free

Case in motivation and teamwork of Starbuck Essay Case in motivation and teamwork of Starbuck Introduction Question 1 Â   Â   Â   Â   Â   Â   Formal teams are teams whose structures are clearly defined mainly of the basis of specialization. In these types of teams, the members are not equal and every one of them has a rank (Moorhead Griffin, 73). For example, there are managers, supervisors and other junior employees. It is worthy noting that every member of a formal team performs their specific duties. For example, managers stay in their offices and issues directives to their juniors. On the other hand, informal teams have no structure and all team members are seen as equal regardless of their specialty. In these types of teams, any member can perform any task. Question 2 A team in Starbucks consists of three to six people and this helps the employees to know each other well. Any opinion expressed by employees is given an equal significance regardless of their position. The top management at Starbucks work together with their juniors which makes them more familiar and closer compared to other bureaucratic companies. The management at Starbucks treats all employees as equals and this is aimed at reducing the gap between the employees and the management. The top management at the company believes that employees are its main spirit. Consequently, the management adopts an interactive organizational structure that makes the employees love their jobs and perform them with passion. Question 3 a) The size of a team is an important factor because it determines how well the team members know each other. This is important because it brings about cohesion in the work place. b) The first benefit of Starbucks having small teams of staff in every branch is that the team members get to know each other better. Secondly, it improves communication within the group. Question 4 Â   Â   Â   Â   Â   Â   From the Starbucks case study, it is clear that there are three major issues that the company needs to address in its planning process namely listening to the opinion of its employees, equal treatment and ensuring good welfare for the employees. Â   Â   Â   Â   Â   Â   Equal treatment- this is one of the major issues that the company needs to address in its planning process. Equal treatment requires all employees to be treated equally regardless of their position. According to the case study, it is clear that the management at the company treats all employees as equals and refers to them as partners. This is important because it narrows the gap between the employees and the management. Treating every employees fairly and equally in the workplace results in a friendly working environment. Consequently, if the issue of equal treatment is addressed in the planning process, it will help in creating closer working atmosphere and good management (Rynes Rosen 64). Â   Â   Â   Â   Â   Â   Listening to the employees- listening to the employees is other issue that requires to be addressed in the planning process. From the Starbucks case, it is clear that the company wants every employee to take part in developing plans and work as a team to achieve the set goals. Consequently, the company’s principles and policies are communicated to all employees, and there is no restriction in the employee’s individual opinions. By listening to the employees, makes them feel important which in turn motivates them hence increasing their productivity (Rynes Rosen, 83). References Moorhead, G., Griffin, R. W.

journalism Essay -- essays research papers

In my twenty years and some months existence in this world, I’ve been fortunate enough to live a secured life. I believe food and shelter are two of the most important essentials in life, and I’ve never had to worry about food not being on the table or if I had a place to sleep at night which is why I consider myself to have a secure life. Volunteering at Simpson Housing helped me realize many things in life, and also made me wonder why some people are so fortunate in life while others struggle to survive in this world. Prior to Simpson Housing, I was vaguely familiar with the issue of homelessness. I only knew the basis of it, but never fully understood it. There are a lot of misconceptions and stereotypes about the homeless and I’ve learned that you can’t really judge until you’ve experienced it. You hear a lot of bad things about homeless people- they’re lazy, drug addicts, bums, freeloaders, etc†¦ It’s easy to focus on the bad because you remember the bad more than the good. It must be hard for homeless people because they are pre-judged without even getting to be known. They get rejected before getting a chance. I will admit that I did believe some of the misconceptions of homeless people because I had one negative experience. When I was younger, my family and I used to go eat at Rainbow, a Chinese restaurant, in Minneapolis. We always went at night and on the way home, there was a strip where all the homeless people would camp out. I couldn’t believe people had to live like that. I’ve had several encounters with homeless people where they’d come up to me asking for money until this once incident. I was with my dad and this lady and her son approached us asking for some help. I had always given a dollar or two before, but I saw she had a son so I convinced my dad to give them five dollars. They seemed to be really gracious of our donation and we felt really good about helping them. Five minutes later, we saw the lady and her son drive away in a brand new Toyota Camry. My dad and I were completely stunned. I was so angry. There are so many others that could’ve used the money we had given. The lady took advantage of us, and completely had no morals whatsoever. However, that did not stop me from wanting to give help to the needy. Instead of giving them money, I give them food. I know it’s not exactly that same, but I still do feel that I am helping them. ... ... but I certain some people have no control over it and that really saddens me. My heart goes out to homeless children because they are so young. They have so much more to worry about when they should only be focusing on having fun as a child and getting their education. However; instead of being able to focus on school, they have to focus on surviving.   Ã‚  Ã‚  Ã‚  Ã‚   Life isn’t fair, but then again what is in life? Situations like homelessness is not something many can touch base with, but it is something we can all take part in to help reduce it. No one deserves to live a life where nothing at all is certain. With so many mistaken beliefs on homeless people, those who are fortunate in life need to realize that those who are homeless are strong in heart. They don’t give up and they keep living each day in hope for a better tomorrow. I’ve learned through volunteering at Simpson Housing is that you have to take the good with the bad and learn from it all. Don’t let the bad hold you down and you should embrace it and turn it into something positive. Whatever may come your way, you should appreciate it because it only helps you grow into the person you are to become.

Gender in the Matrix Essay

The Matrix became one of the most notable films released in 1999 which provided rich visual effects and a thrilling storyline. Most of the scenes from this film play within the context of the future, a visual offering of year 2199 wrapped in virtual reality where machines govern and control human actions. Though the film deals with the relationship between machines and humans, every character in the plot represents an underlying gender-related interaction. Since the film basically revolves on the cyber world in the form of a simulation created by machines, gender specific plots are not explicitly conveyed throughout the whole duration of The Matrix. The following discussion will focus on some of the gender dynamics present within the film. The paper will analyze some parts of the film where norms of gender are either contradicted or affirmed. As previously mentioned, the world in which the main characters believed to be real, is manipulated by intelligent machines. These machines utilized human body heat to convert into energy while they control human behaviors within the matrix. In the general sense machines are considered as a non-living thing created by man and from this perspective, machines do not have a specific gender. In this film they can be considered as androgynous, the Agents who can take any virtual body for their usage is an example on how the machines in this film are androgynous. Contrary to the real world, these androgynous machines have the power over humans with no concept of male and female. Somehow, it projects a balanced and equal form of gender treatment. First of all, there is no direct interaction between genders since their physical bodies are trapped inside a tank connected to the simulation. Second, all humans are used and contained for a single purpose that no other humans can dominate. Seeing the domination of machines as a projection of gender balance, the concept of the â€Å"ONE† enters the scene. It has been revealed from the start that Neo – the male protagonist of the film – is the savior of the human kind. This can be regarded as an obvious manifestation of upholding patriarchy, since the real world is where men are associated with power. From the world matrix where men and women are controlled, a man is predicted by the Oracle to save the humans from the machine’s imprisonment. Naturally, to the film’s audience, Neo’s success is attributed to the male strength and the power of patriarchy. The female character of Trinity shows her strength which is equal to her male counterparts. However, this strength seems to compliment her appearance which resembles Neo, who has the same shape of face, same sunglasses, and same battle moves. From earlier scenes of the film, Neo mistaken her for a man who cracked a difficult code called IRS d-base (The Matrix 1999), a scene where intelligence are stereotyped among males is reinforced. This film has been said to draw out some of its concept from theological concepts. Neo being the ONE symbolized as the God who is the savior of humankind while Trinity – derived from God’s three dimensional forms – represents Neo not just in physical traits. The kiss she gave to Neo when he died miraculously revived him which can be compared to the Holy Spirit (Diaz-Diocaretz & Herbrechter 200). The issue of gender in The Matrix tackles the usual gender norms of exhibiting male power and dominance. The balance of gender interaction within the simulated environment became the antagonist throughout the film where the characters try to escape. Agent Smith said that the real world is shaped by misery and suffering and the purpose for the creation of the Matrix is to build a perfect world for humans where everyone is treated equally. Ironically, the concept of equality in the film is one thing that needs to be eradicated. Works Cited Diaz-Diocaretz, Myriam. , and Herbrechter, Stefan. The Matrix in Theory. New York: Rodopi, 2006.

Yeats Easter

â€Å"Easter 1916† – manuscripts the events of Easter revolution in Ireland. It was Written in 1916 and Published only in 1921. The Question remains in the readers mind that â€Å"Was the revolution really necessary or was it unnecessary death? † The language in poem is simple and straight which makes use of figure of speech like slimly and metaphor. The poem conveys the moral that individual, war, friendship and relationship are more important in the world.We must have self control and shouldn't complain if the things go wrong. In the poem Yeats is taking the role of flamers and he is giving the description of normal dally lives of people. He also tells that he wants to go and meet his friends at theatre and say â€Å"A terrible beauty Is born†. This shows a dualistic nature of rising. It said a terrible beauty because It caused death and beauty of their step towards Independence. The revolution caused many problems which ruined the normal days of people as shown in the poem.Yeats describe about a revolutionist woman leader to be placed at a cabinet position ho is both a socialist and politician. She was left alone in Ireland by her husband who moved to Ukraine. She belongs to IIRC and designed uniform and national anthem for IIRC. RIB Leaders includes Patrick Pears: Leader of RIB, teacher, poet, nationalist and activist. Pears, he was the head of RIB and he delivered the proclamation speech on 24th of April at General Post Office. The second includes McBride: Member of RIB, husband to Yeats Love; Maude Gonne.Thirdly, James Connelly: Who Founded Irish Republican Society and Irish Citizen Army he was ideation at G. P. O leading 150 rebels as commandment- General. Followed by Marketable a Nationalist, suffragette and socialist, she Is also a first woman to hold cabinet position In world. She Designed uniforms and composed anthem for RIB. She motivated and inspired many other revolutionist. Lastly Macdonald: who contributed to the Proc lamation speech. He was stationed at Jacob Biscuit. They planned a movement during the early spring to actually revolt against British rules.By then England was heavily involved in war with their allies. Irish nationalists ND revolutionist thought it would be great opportunity to fight for the revolution. They made friends with Germany and got helped in terms of weapons and ammos to fight against Britain. Yeats have written this poem as legacy in memory of Macdonald, McBride, Connelly, and Pears who are all untied by their commitment to their dream of freedom, giving Ireland everything they could for the good thing to happen.Yeats continues to say, wherever the split of Ireland Is represented by people wearing the color â€Å"green,† and those people will be forever changed-Yeats also describes how nature is corresponding to the Irish revolution which is very that is to achieve freedom for Ireland as if like a stone which can be resembled as an island of destiny because of th eir excessive love towards Ireland which made them revolt against British rules. Revolution is simply disturbing the social lives of people and their privacy.It means if the revolution continues then there is the chance that people will become emotionalism with heart in nature which can further more lead to much destruction. Yeats says only God can help. Though Ireland is happy for its independence Yeats is not as happy about the revolution as he says that those revolutionaries were very impatient to gain independence as British rules has actually promised the homeland for self governing but revolutionaries were so eager to fight.The revolution left 300 civilians, 200 soldiers & revolutionist dead, 2500 wounded, 15 leaders executed and 1841 sent to prison. The main theme if the poem is Art and politics which reflects Yeast's opinion of the British politics on Ireland. The Impact of fate and Divine on History is also included in the poem. He explains to us about the Fate and historic al determinism time. We can also see Yeast's transformation from being romantic poet to modernist poet. The poet has a perfect command over words.He has also deep insight in to human character. The characters of RIB have been pointed with great skills which seem simply is unforgettable. This shows the basic honesty and simplicity of the poet. The poem ends on a note of hope as the poem makes delightful reading simply because the very sincere about his ideas. He neither neither boasts nor hide anything. The toe is a patron of music and possesses a pictorial quality to build up an atmosphere of rare charm and reality.The quality of the poem is unquestionable. I can't name another poet which contains so much beauty as this person. The poem is very much optimistic and sentimental with the help of deep poetic inside. He creates realistic feeling in the readers mind. â€Å"Wherever green is worn/Are changed, changed utterly' these lines are unforgettable and a delight wonders. The poet o scillates between the present and the past, between Joy and despair and feels miserable.

Progress of Technology essays

Progress of Technology essays Personal computers were officially introduced just around 15 years ago and already changed our lives dramatically. People that were born around that time rely on computers a lot more than older generations. We use computers for just about everything like instant messaging, games, homework, music and e-mail; just to name a few. I think that advances in technology and, therefore, computers have mostly a positive effect on humans. They replace peoples jobs and do them millions of times faster. We wouldnt be able to launch any spaceships if it wasnt for the computer helping humans control it. Homework and research would take hours to complete because you would have to look for different sources everywhere and now you just log onto the internet and all known encyclopedias are at your fingertips. Computers these days can be found everywhere from being the brain of new cars and helping you drive without getting lost to just sitting on your arm and telling you the correct time. A computer isn't just the thing that sits on your desk to be used for word processing. They are amazing machines able to do things some people don't even think possible. Computers are helping humans live. They take off many responsibilities so people just watch the numbers on the screen and not worry about anything else as the computer does the rest. Computers also save lives. SWAT teams use them inside radio controlled robots that can disarm all sorts of bombs or even serve as a camera to go through small spaces that people can't get through. A computer is something not to be underestimated. Computers are not only becoming faster every day but they are also becoming smaller. Around 40 years ago, computers were as big as several rooms and needed thousands of times more power than a personal computer today. All they could do was simple arithmetic operations that nowadays can be performed on any tiny hand-held calculator. Soon people will carry their...

An Introduction to Black Holes

An Introduction to Black Holes Black holes are objects in the universe with so much mass trapped inside their boundaries that they have incredibly strong gravitational fields. In fact, the gravitational force of a black hole is so strong that nothing can escape once it has gone inside. Not even light can escape a black hole, it is trapped inside along with stars, gas, and dust. Most black holes contain many times the mass of our Sun and the heaviest ones can have millions of solar masses. This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black holes event horizon, where no light can escape the massive objects gravitational grip. The black holes powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as the stars skim by the black hole. NASA, ESA, and D. Coe, J. Anderson, and R. van der Marel (Space Telescope Science Institute), Science Credit: NASA, ESA, C.-P. Ma (University of California, Berkeley), and J. Thomas (Max Planck Institute for Extraterrestrial Physics, Garching, Germany). Despite all that mass, the actual singularity that forms the core of the black hole has never been seen or imaged. It is, as the word suggests, a tiny point in space, but it has a LOT of mass. Astronomers are only able to study these objects through their effect on the material that surrounds them.  The material around the black hole forms a rotating disk that lies just beyond a region called the event horizon, which is the gravitational point of no return. The Structure of a Black Hole The basic building block of the black hole is the singularity: a pinpoint region of space that contains all the mass of the black hole. Around it is a region of space from which light cannot escape, giving the black hole its name. The outer edge of this region is what forms the event horizon. Its the invisible boundary where the pull of the gravitational field is equal to the speed of light. Its also where gravity and light speed are balanced. The event horizons position depends on the gravitational pull of the black hole. Astronomers calculate the location of an event horizon around a black hole using the equation  Rs 2GM/c2.  R is the radius of the singularity,  G is the force of gravity, M is the mass, c is the speed of light.   Black Hole Types and How They Form There are different types of black holes, and they come about in different ways. The most common type is known as a stellar-mass black hole.  These contain roughly up to a few times the mass of our Sun, and form when large main sequence stars (10 - 15 times the mass of our Sun) run out of nuclear fuel in their cores. The result is a massive supernova explosion that blasts the stars outer layers to space. Whats left behind collapses to create a black hole. An artists conception of a stellar-mass black hole (in blue) hat likely formed when a supermassive star collapsed, feeding from material ejected by a nearby star. ESA, NASA and Felix Mirabel) The two other types of black holes are supermassive black holes (SMBH) and micro black holes. A single SMBH can contain the mass of millions or billions of suns. Micro black holes are, as their name implies, very tiny. They might have perhaps only 20 micrograms of mass. In both cases, the mechanisms for their creation are not entirely clear. Micro black holes exist in theory but have not been directly detected. Supermassive black holes are found to exist in the cores of most galaxies  and their origins are still hotly debated. Its  possible that supermassive black holes  are the result of a merger between smaller, stellar-mass black holes and other matter. Some astronomers suggest that they might be created when a single highly massive (hundreds of times the mass of the Sun) star collapses.  Either way, they are massive enough to affect the galaxy in many ways, ranging from effects on starbirth rates to the orbits of stars and material in their near vicinity. Many galaxies have supermassive black holes at their cores. If they are actively eating, then they give off huge jets and are known as active galactic nuclei. NASA/JPL-Caltech Micro black holes, on the other hand, could be created during the collision of two very high-energy particles. Scientists suggest this happens continuously in the upper atmosphere of Earth and is likely to happen during particle physics experiments at such places as CERN.   How Scientists Measure Black Holes Since light can not escape from the region around a black hole affected  by the event horizon, nobody can really see a black hole. However, astronomers can measure and characterize them by the effects they have on their surroundings. Black holes that are near other objects exert a gravitational effect on them. For one thing, mass can also be determined by the orbit of material around the black hole. A model of a black hole surrounded by heated ionized) material. This may be what the black hole in the Milky Way looks like.

Black holes, like all massive objects, have enough gravitational pull to bend lights path as it passes by. As stars behind the black hole move relative to it, the light emitted by them will appear distorted, or the stars will appear to move in an unusual way. From this information, the position and mass of the black hole can be determined. This is especially apparent in galaxy clusters where the combined mass of the clusters, their dark matter,  and their black holes create oddly-shaped arcs and rings by bending the light of more distant objects as it passes by.   Astronomers can also see black holes by the radiation the heated material around them gives off, such as radio or x rays.  The speed of that material also gives important clues to the characteristics of the black hole its trying to escape. Hawking Radiation The final way that astronomers could possibly detect a black hole is through a mechanism known as Hawking radiation. Named for the famed theoretical physicist and cosmologist Stephen Hawking, Hawking radiation is a consequence of thermodynamics that requires that energy escape from a black hole. The basic idea is that, due to natural interactions and fluctuations in the vacuum, the matter will be created in the form of an electron and anti-electron (called a positron). When this occurs near the event horizon, one particle will be ejected away from the black hole, while the other will fall into the gravitational well. To an observer, all that is seen is a particle being emitted from the black hole. The particle would be seen as having positive energy. This means, by symmetry, that the particle that fell into the black hole would have negative energy. The result is that as a black hole ages, it loses energy, and therefore loses mass (by Einsteins famous equation, EMC2,  where Eenergy, Mmass, and C is the speed of light).

Organ Transplants Essay Example | Topics and Well Written Essays - 1750 words - 1

Organ Transplants - Essay Example If the black market is analyzed, it is seen that most of the sellers are poor while most of the buyers of organs are comparatively wealthy (Satz 10). Most of the organ transfers in the black market are from the poor to the rich, from the third world countries to the first world countries, from non-whites to whites and from females to males (Satz 10). Why is it that these trends reflect the long perceived inequalities in society? There certainly is a link between organ transplantation and societal inequalities, be it on an economic or a health front. This paper thus argues that organ transplants can cause inequality within society. Organ transplantation will demarcate and enhance the pre-existing inequalities in society. As per statistics laid out by the National Kidney Foundation, more than 89,000 patients in the US are currently awaiting organ transplant and about 4000 additional patients are added every month to the waiting list (unckidneycenter.org 1). Each day, 17 patients die waiting for a transplant (1). In 2004, 3,886 patients waiting for kidney transplant, 1,811 patients waiting for liver transplant, 457 patients waiting for heart transplant and 483 patients waiting for lung transplant died while waiting (1). Estimation of people who meet premature death simply waiting for organ transplants is difficult. Worldwide, it is estimated that 700000 patients are on dialysis and in need of kidneys (Erin and Harris 137). In Western Europe alone, 40,000 people wait for kidney transplantation while only 10,000 kidneys become available (137). It is thus obvious that there is a huge shortage of organs, so much so that governments worldwide are considering the prospects of a legalized organ market! Howev er, it is feared that such a market will lead to exploitation of those (such as the poor) who are in desperate need of money, or those (such as women or weak sections of society) who are forced to sell or donate their organs for various reasons.
