Free Essays on The Lion In Love
The Lion in Love is a fable about a lion that falls in love with a woodcutterââ¬â¢s daughter. The lion demanded the daughter in marriage but her father would not grant his request. The daughter was fearfully afraid of his claws and teeth, and after serious consideration, the fathersââ¬â¢ willingness to accept the Lion as a suitor of his daughter under one condition, that he would allow him to extract his defenses, such as his teeth, and cut off his claws. The lion assented to the fathersââ¬â¢ proposal. When the toothless and clawless lion returned to repeat his request to marry his daughter, the woodcutter, no longer fearing the lion, sat upon him with his club and drove him into the forest. This fable represents the good and evil in the world. The lion only wanting to marry his daughter out of love and father only wanting him to give up his defenses so he could never fear him again shows that out of something good comes evil. The morals of the story is to never resign to your own defenses; love can blind even the wildest; and an extravagant love consults neither life, fortune, nor reputation, but sacrifices all that can be dear to a man of sense and honor, to the transports of an inconsiderate passion. The ideology of this fable is that when you give up your defenses and who you are you lose a part of you. If you have to give up your dignity and honor of who you are for someone you love then you should not be with that person. I think in todayââ¬â¢s society some people change who they are to make the person they want to be with happy. If it takes changing who you are to make someone else happy, I believe you donââ¬â¢t even need to be with that person. If a person is not happy with whom you are then they do not need to be with you. In this fable, the lion gives up his defenses in order to marry the woodcutterââ¬â¢s daughter, but in the end it never changed anything except the fact that he lost who he was, and yet he still did not...

Lord of the Flies5 essays
Lord of the Flies5 essays In the book The Lord of the Flies the beast turns out to be the boys worst enemy even though it never really existed. The beast turned out to be the boys themselves. They were all scared the beast would kill them, but they ended up hurting or killing themselves just by defending themselves from the The first sign of the beast was when the boys were first scared. When the little boy told the rest of the boys about the snake-thing he saw in the woods he refers to it as the beastie. None of the boys really believe him, but in all their minds it gets them thinking and worring about whats on the island, and if there are any beasts of some sort. The beast occurs any time the boys are frightened. If they hear a noise in the woods it must have be the beast. If they see something that scares them it must be the beast. This freightenment works the boys up so much that their primary goal is to kill the beast. In the end they kill themselves, and they realize that they were running from themselves. The beast never existed I think the author, Golding, felt the same why when he wrote the book. The beast is the boys, and it ends up being their worst nightmare, and they dont even know it. That interpetation of the beast changed throughout the book and i began to realize what the author meant by the beast. ...

SWOT analysis for outsourcing a business function, in this case - Essay
SWOT analysis for outsourcing a business function, in this case - inventory management to cloud computing - Essay Example Secondly, lack of knowledge of any particular company would lead to an inefficient service being provided by companies such as Cloud Computing at the expense of the time and resources of its client. The inventory function is one function that is central to any organizationââ¬â¢s entire business, hence it should be kept in-house rather than out-sourcing it to companies like Cloud computing because it might further increase the chances of fraud and theft. The opportunities and risks that may arise would be: Opportunities: Specialist vendors would really manage the inventory management system more efficiently if they get good knowledge of the companyââ¬â¢s activities, culture, environment, etc. Time would be saved Cyber embassies, if created, would really help in obtaining data from far away locations. Data could be retrieved quickly if the region of operation of the company is same where the cloud computing office exists. Focus of the business would divert towards the improvement of the business rather than focusing on the inventory management system Risks/Threats: The inventory management function might not be easily understood by Cloud Computing Having older and newer licenses would both have their respective complications. Data could not be easily accessible in any other regions e.g. a company operating in the EU would not be able to store its data with a U.S vendor.

Singapore Model Essay Example | Topics and Well Written Essays - 1000 words
Singapore Model - Essay Example Singaporeââ¬â¢s description of state capitalism is that the government has controlling shares in various public corporations and issue funding through the sovereign wealth fund (SWF). The SWF is state-owned capital funds used for real and financial asset investments in stocks, bonds or other alternative ventures. The funds are applied universally from export revenues or foreign exchange reserves in the custody of the central bank. Considering this, Singapore attracts multinational organizations to take the global SWF benefits. The country also imposes business friendly regulations that favor the establishment of multinational organizations. The Singaporeââ¬â¢s capitalism Model incorporates the private and public-owned companies towards an overall contribution to the economy (Tajuddin 54). The availability of the SWF has enhanced domestic investment in which the local industries are capable of manufacturing large-scale production. As a result, the state-owned companies transform into global enterprises that serve other regions with quality products. It is apparent that the SWF contribute to government social spending without raising taxes because they represent the budgetary surplus owned by the central bank. Similarly, the SWF does not have international debts accrued from government borrowing. The country creates SWF in order to boost economic activities inspired to promote the state-owned enterprises. Singapore depends on services and manufacturing exports, with little government interference.

3d Printing Technology Essay Example for Free
3d Printing Technology Essay Legitimate Concerns Facing 3D Printing Technology Executive Summary This research journal article discusses how 3D Printing technology may effect federal firearms regulations. The focus of the article is that, due to the development of 3D Printing technology, individuals, even people without technical expertise, now have the ability to use the new technology to produce guns at home much more easily than they ever have before. This behavior might bring great harm to society. However, if a comprehensive prohibition on using 3D Printers to manufacture personal weapons were implemented, it might defy the 2008 District of Columbia v. Heller Supreme Court decision. In fact, the increasing popularity of 3D Printing means lawmakers must decide soon whether or not to allow 3D Printing of weapons. 3D Printing either should only be allowed to produce things that cannot be used as lethal weapons. Or, secondly, it can be used to produce a physical, working gun. The second option might achieve advances in 3D printing technology and promote the development of firearms design. However, developments in 3D Printing technology are creating concerns that not only legitimate consumers but also criminals are able to ââ¬Å"printâ⬠firearms at home. If the law doesnââ¬â¢t allow individuals to use 3D printers to manufacturer personal weapons like handguns, it might be illegal according to the Second Amendment of the Constitution, a provision which protects the right of individuals to possess firearms under the law. Specifically, under the 2nd Amendment individuals may have the right to create their own firearms for self-defense, and the right to the manufacture firearms technology and materials. Analysis and Critique In fact, 3D Printing technology is not brand new. This technology has been undergoing development for more than a decade. The reason it became more popular recently is because of decreasing usage costs, so more and more individuals have the opportunity to own 3D Printers for personal use. In my analysis and critique of this journal article, I will focus on three different areas: how well does it deliver information to the reader, how the product will evolve in the future, and what is my opinion of concern about 3D Printing technology relate to firearms production after reading this journal article. First of all, this article is well organized and divided into four parts. The first part introduces what 3D Printing is, and how it is possible to produce firearms using the technology. The second part explains why the sale and production of firearms are limited under federal regulations, and provides an overall outlook of the firearm industry. Part three includes explanations of how 3D printers may change firearms production. Finally, Part four describes the constitutional right to bear arms, and it also analyzes the extent to which Hellerââ¬â¢s case may limit prohibitions on 3D Printing. Moreover, this article provides other critical information to explain key points. It is a very valuable introduction for a reader without a background in the subject who might not be very familiar with the IT industry or with the relevant legislation. Based on the data and supporting details provided by the author, readers will have a basic idea of the fundamental issues concerning the intersect ion of 3D Printing and weaponry. As a result, it relates the technology to big concerns about public security, and the author gives great examples of the various legal arguments on the topic. Therefore, I think this article is a valuable qualitative article that can expand peopleââ¬â¢s knowledge on the subject. Secondly, besides concerns about guns, there are no other disadvantages to the improvement of 3D Printing, which will make the operating cost of the technology increasingly cheap. Jensen-Haxel explains how 3D Printing actually works in his article: The process begins with a digital 3D model created using Computer Added Design (CAD) software. The software automatically slices the model into a stack of thin horizontal cross-sections about 0.1mm in height. The, 3D printer then builds the physical model by depositing material layer by layer. At the same time, 3D Printers are getting smaller and smaller, which will make it easier for consumers to have their own machines at home. This changes the old production model. Nowadays, people are allowed to produce whatever they want using a 3D Printer, all they need are the required data and materials. In fact, because of the development of the Internet, it is easier than ever for people to find these resources online. Evans states that: The quickest way to get started with 3D printing is simply to find models online that others have already created and shared on the Internet. The online 3D printing community is growing all the time, so more and more things are being shared every day. Therefore, the limitations of self-production have shifted from hardware difficulties to software or materials issues. The technology is becoming simpler to use, but it might harm light manufacturing industries because some designers may be able to use their own 3D Printers to produce a sample instead of finding established producers that use traditional manufacturing methods. Because of these improvements, the potential for 3D Printing is bright, but the light manufacturing industry might be negatively affected by it. Finally, the author argues that the rapid improvement of 3D Printing and the increasing convenience for individuals to produce things with it is both a major concern and a tremendous possibility. Should individuals receive the right to do whatever they want with 3D Printing technology, even the ability to ââ¬Å"printâ⬠firearms? The topic of gun safety has become especially relevant since the school shooting in Newton, Connecticut last year. More and more people are arguing about if the government should make some changes to firearms regulation. Jensen-Haxel wrote in his article that: ââ¬Å"As the power of production passes from industry to consumer, many areas of the law may be caught unprepared.â⬠(P.448) Concerns about the rate of technological progress outpacing regulations are not limited to 3D Printing. Because of the relentless improvements to technology, more and more challenges will occur as regulators try to manage new technology. The fact is, in most cases, laws only change after a new problem occurs, which means that new products will often exist in a legal gray area before rules can be changed. How the government deals with this issue might be a big concern in the following decades. To sum up, this article first introduces 3D Printing technology, and gives an example how 3D Printing has been used to ââ¬Å"printâ⬠a firearm. As a result, the author relates this new technology to a regulatory concern. Within his argument, he provides lots of legal information, and then tries to point out a fact that some gray areas exist because regulation usually develops slower than a new technology can. Back to this article, is seems like the future of 3D Printing technology in unclear until the government resolves the legal issues concerning manufacturing weapons with this technology.

Transcription from a Broadcast of Network 23 :: Television Programs Los Angeles Essays
Transcription from a Broadcast of Network 23 The following is a complete verbatim transcription from a recent broadcast of "Network 23", a program shown on a local Los Angeles Public Access Cable Channel.Good evening, I'm Michel Kassett. This is Network 23. A couple of weeks ago we had a program on the subject of AIDS, addressing the question of whether AIDS-the AIDS virus-was created by the government; and I'm sure that some people were quite shocked by what they heard. We spent that entire program relating to you the evidence of a very substantial amount of factual evidence which supports the proposition that AIDS is a synthetic biological agent that was deliberately engineered by the US government as an instrument of depopulation. This is by far the most controversial and dangerous subject that we have ever addressed on this program, so I would like to review briefly the major points-the most significant pieces of evidence-that I presented two weeks ago.The first point was that in the early 1970's, Henry Kissinger wrote a top secret document-a National Security Memorandum ("NSM 200") -- in which he indicated that "depopulation should be the highest priority of US foreign policy towards the Third World." This Memorandum which can be obtained from the US National Archives, which was only declassified very quietly in 1990, was adopted by the National Security Council as official US foreign policy towards the Third World. Now, this is a classic example of the "secret government" in action, because of none of this was known to the Congress, and certainly, it was not known to the American people. Did any of you know that depopulation was considered a matter of US national security? Did any of you know that for the p ast 20 years, depopulation has been the highest long-range priority of US foreign policy towards the Third World? No you didn't, because it was classified-it was a secret.I would like to read for you just a piece of this document. It is written by Henry Kissinger:"Reduction of the rate of population in these States is a matter of vital US national security." [National Security Memorandum, Henry Kissinger]And we even have a map of those areas in which Kissinger indicates where depopulation would be desireable. It's all Third World countries- it's all brown people and yellow people, of course."The US economy will require large and increasing amounts of minerals from abroad, especially from less-developed countries.

Alumni Tracer System
The Alumni tracer is a System that even they are far from the schools, the schools can communicate with the graduate students and to know more about their experiences and their careers after finished their studies. Technology is a tool and method used in solving problems and to make the work easier. In our modern generation, almost everything around us is made-up of technology and the most developed gadget in our generation is the computer wherein almost everyone needs it. Students, Teacher, or even a simple user can do anything they want in computers. It can make to help us to make our work easier and faster. Every schools-universities or institutions are using computers. Some of schools wants to remember all those person who have been part of their society, thatââ¬â¢s why they want to know if the students from their school has a capability to compete their knowledge or skills to everyone and they want to know more about the students who are already graduated. College has always placed great emphasis on the importance of maintaining a close rapport with its alumni. In order to build and enhance the alumni network, the Alumni Affairs Office was established to act as an intermediary platform in bridging the gap between the College and its vast alumni members. It actively plays its role in maintaining a good relationship between the alumni and College as well as extending dynamic network between alumni from various School of Studies. The Alumni Affairs Office also plays an integral part in organizing various homecomings, thus effectively keeping the communication channel between the College and its alumni open, providing countless opportunities for its alumni in strengthening its networking ties and forging an everlasting bond of fellowship. Thus the researchers came up with an idea of creating an online alumni tracer. The Alumni Tracer is being used by several schools to conduct significant feedback, to reconnect graduates to their alma mater and to know the demographic profile of the employment record of the respondents. Several schools in the Philippines nowadays have been using it and integrate it through their official websites and/or alumni associationââ¬â¢s page.

Modern Life vs Village Life Essay
Many towns and villages then are nothing more than suburbs today. By definition cities have larger populations than towns which are larger than villages, which is a major difference between modern life and village life. In todayââ¬â¢s Modern life cities have an urban settlement with large populations where as villages were settlements of community with small populations. Modern life have many advantages over village, because city modern life facility are easily available, as telephone , gas , internet, schools, colleges, universities, hospitals, industries, factories, roads, airports, railway stations and many were most, but most village are deprived of these many facilities like many villages no facility of gas, telephone , roads, etc. ââ¬Å"The Telephone,â⬠Accawi offers an unpretentious description of how the modern world began its intrusion into a timeless and insulated culture, where ââ¬Å"there was no real need for a calendar or a watch to keep track of the day, hours months, and yearsâ⬠. Read more: Essay on village life As Accawi says of village life:â⬠we lived and loved and toiled and dies without ever needing to know what year it was, or even the time of day. â⬠Village life is slow moving and more agriculturally based while city is the center for trade, commercial industry and education. Modern life is always on the go, there are many offers for pleasures, opportunities for jobs, if you have a good job you can live well. The village was a traditional place where everyone enjoyed life and being around each other. Although village life had its pleasure, but it also had its flaws. In village life there were more chances of dying then in modern life . Forexample health care wise, assistance is wasnââ¬â¢t always available in the village if someone was in danger they would of had to rely on their own resources. Medical help is more easily available in modern life. Villages were miles and miles away from the nearest hospital or police station. But in a city with EMS the nearest hospital or clinic is just a few seconds away. Mordern dangers like traffic are constant but it is rarely pointed out that villages had their dangers too. A child playing in a village park may get bit by an wild animal. Wild animals are more of a threat in villages and may carry disease. But to belive that village life is safer than modern isnââ¬â¢t necessarily true. A was a threat is a threat whereevery it occurs A village child may grow up with the appreciation of birds and the wonders of the out doors and miss out on priceless opportunites in the modern day life. Modern life may have its flaws, but the opportunity given outweighs them. Morden life may seem preferable to the village life, because of technology and large scenery, but there are some disadvantages too, the cost of the living is high in the city, the city is noisy, no fresh air nor pure water. So it is hard to live a healthy life. People living in cities are different but similar from people living in villages. It is normal to us that city life is more enjoyable than village life. From our prospective of modern life, city life is filled with a lot of advantages. This is because of the fact that there are a number of opportunities open to you in modern life . City life is provided with a lot of facilities too. The behavior of the people in village life is different from the people in modern life. The people in villages on the other hand are warm-hearted and friendly. People in villages are very helpful in nature whereas people living in cities tend to be more selfish in their attitude. Villagers accept you well where as modern life people tend not to. Itââ¬â¢s quiet, peaceful and the air was fresh in the village life, employment was seasonal for example farming witch is similar to roofers in the modern life,during the rainy season and brick making in the dry season. Wages brung better way of living to many familes in the village life, villagers were able to trade things and purchase farming goods from farmers like we trade and purchase food from our modern day markets. But You would not find many facilities and opportunities in a village. Parents would be love to send their child to the city for higher studies rather than to villages. The city is filled with quality higher education institutions whereas villages do not have with high quality colleges and universities. As read in the ,the villagers did not have much, and technology was very new to them. Fore example they judged time by certain events that happened. The birth of someone important or earthquake would be enough to grasp time. The children would play in the streets and run errands for the grown ups for money. Accawi grew up in this town and he was quietly statisfied and happy with his life. He woundnââ¬â¢t be to kindly of change because he had fun without all the advantages of technology. Assuming everyone else was happy as well. However, when the telephone came, it changed their lives forever. The telephone brought so many opportunities for the villagers. As read in the text ââ¬Å"the whole village would sit by the phone and wait for it to ring and bring them news, and opportunities to make moneyâ⬠. The people of Magdaluna fell in love with the phone. The crowd around the phone grew larger and larger. People would receive job and leave the village. This was upsetting to many people of Magdaluna, especially Accawi. . I can agree with Accawi,I miss my home town in Haiti, migrating to America was a lot to take in. Like Accawi I was so acostume to the way of living in Haiti, so similar to the village life in Magadluna. But once my father found a better job in America we moved out as soon as possible. facing a variety of finical problems crime, drugs, corruption, a troubled my town my father was overwhelmed and dissatisfied with the direction of our town. He believe life was better in the United States. Close to 70% of my town say that people who move from hatiti enjoy a better life in the U. S. And the vast majority of those who are in regular contact with friends and relatives living in the U. S. say those friends and relatives have largely achieved their goals.

Positive vs. Negative Commands in Spanish
Positive vs. Negative Commands in Spanish Spanish uses a different verb form for positive direct commands (such as do it) than it does for negative direct commands (dont do it) in the familiar second-person form, that is, when speaking to tà º or vosotros. Note the differences with the following regular verbs, all of them in the imperative mood. Pronouns in parentheses are optional and are included here for clarity: habla (tà º) (speak, you singular); no hables (dont speak, you singular); hablad (vosotros) (speak, you plural); no hablà ©is (vosotros) (dont speak, you plural) come (tà º) (eat, you singular); no comas (dont eat, you singular); comed (vosotros) (eat, you plural); no comis (vosotros) (dont eat, you plural) vive (tà º) (live, you singular); no vivas (dont live, you singular); vivid (vosotros) (live, you plural); no vivis (vosotros) (dont live, you plural) The same endings are usually used for most of the irregular verbs as well. Note that the negative form of familiar second-person commands is the same as the present subjunctive form. Here are some examples of sentences showing the difference with irregular verbs: Ve a casa. (Go home, singular) No vayas a casa. (Dont go home.) Id a casa. (Go home, plural) No vayis a casa. (Dont go home, plural.) Hazlo. (Do it.) No lo hagas. (Dont do it.) Hacedlo. (Do it, plural.) No lo hagis. (Dont do it, plural.) Dime. (Tell me.) No me digas. (Dont tell me.) Decidme. (Tell me, plural.) No me digis. (Dont tell me, plural.)

Starburst Galaxies
Starburst Galaxies The universe is filled with galaxies, which are themselves filled with stars. At some point in its life, each galaxy bristled with star formation in vast clouds of hydrogen gas. Even today, some galaxies seem to have more than the usual amount of star birth activity and astronomers want to know why. There were so many stars being born in some galaxies in earlier times that they probably looked like cosmic fireworks bursts. Astronomers refer to these hotbeds of star birth as starburst galaxies. Key Takeaways: Starburst Galaxies Starburst galaxies are galaxies where high rates of star formation has occurred very quickly.Nearly all types of galaxies can undergo starburst events if conditions are right.Astronomers know that starburst galaxies are often involved in mergers that mingle stars and gas. Shock waves push the gas, which sets off the starburst activity. Starburst galaxies have unusually highà rates of star formation, and those bursts last for a short time during the galaxys long life. Thats because star formation burns through the gas reserves of the galaxy very quickly. It is likely that the sudden burst of star birth is triggered by a specific event. In most cases, a galaxy merger does the trick. Thats when two or more galaxies mesh together in a long gravitational dance and eventually meld together. During the merger, the gases of all the galaxies involved are mixed together. The collision sends shock waves through those gas clouds, which compress the gases and set off bursts of star formation.à Properties of Starburst Galaxies Starburst galaxies are not aà new type of galaxy, but rather simply a galaxy (or mingled galaxies) in a particular phase of their evolution. Even so, there are some properties that show up in most starburst galaxies: a very rapid star formation rate. These galaxies will produce stars at rates well above the average rate of most regular galaxies; availability of gas and dust. Some galaxies may have higher than normal star-formation rates simply due to their high volumes of gas and dust. However, some starburst galaxies do not a have the reserves to justify why they would have such high rates of star formation, so mergers may not be the only explanation;star formation rate is inconsistent with the age of the galaxy. The main point is that the current rate of star formation could not have been constant since the formation of the galaxy given its age. An older galaxy simply wouldnt have enough gas left over to keep up starbirth action for billions of years. In some starburst galaxies astronomers see a sudden burst of star birth, and often the explanation is a merger or chance encounter with another galaxy. Astronomers sometimes also compare the rate of star formation in a galaxy relative to its rotational period. If, for example, the galaxy exhausts all of its available gas during one rotation of the galaxy (given the high star formation rate), then it can be considered a starburst galaxy. The Milky Way rotates once every 220 million years; some galaxies go much slower, others faster. Another widely accepted method to see if a galaxy is a starburst is to compare the star formation rate against the age of the universe. If the current rate would exhaust all of the available gas in less time than 13.7 billion years, then its possible that a given galaxy may be in a starburst state.à Annotated image showing dazzling eyelid-like features bursting with stars in galaxy IC 2163. A tsunami of stars and gas triggered by a glancing collision with galaxy NGC 2207 (a portion of its spiral arm is shown on right side of image). ALMA image of carbon monoxide (orange), which revealed motion of the gas in these features, is shown on top of Hubble image (blue) of the galaxy. M. Kaufman; B. Saxton (NRAO/AUI/NSF); ALMA (ESO/NAOJ/NRAO); NASA/ESA Hubble Space Telescope Types of Starburst Galaxies Starburst activity can occur in galaxies ranging from spirals to irregulars. Astronomers who study these objects classify them into sub-types that help describe their ages and other characteristics. Starburst galaxy types include: Wolf-Rayet galaxies:à defined by their ratio of bright stars that fall into the Wolf-Rayet classification. Galaxies of this type have regions of high stellar wind, driven by the Wolf-Rayet stars. Those stellar monsters are incredibly massive and luminous and have very high rates of mass loss. The winds that they produce can collide with regions of gas and drive rapid star formation.Blue compact galaxies:à low mass galaxies that were once thought to be young galaxies, just beginning to form stars. However, they usually contain populations of very old stars. That usually is a good clue that the galaxy is quite old. Astronomers now suspect that blue compact galaxies are actually the result of mergers between galaxies of varying ages. Once they collide, starburst activity ramps up and lights up the galaxies.Luminous infrared galaxies:à dim, hidden galaxies that are difficult to study because they contain high levels of dust that can obscure observation. Typically infrared radiation à detected by telescopes is used to penetrate the dust. That provides clues to increased star formation. Some of these objects have been found to contain multiple supermassive black holes, which can shut down star formation. The increase in star birth in such galaxies has to be the result of a recent galaxy merger. Cause of Increased Star Formation Although the merger of galaxies is pinpointed as the main cause of star birth in these galaxies, the exact processes are not well understood. Partially, this is due to the fact that starburst galaxies come in many shapes and sizes, so there may be more than one condition that leads to increased star formation. However, for a starburst galaxy to even form, there must be lots of gas available to generate the new stars. Also, something must disturb the gas, to begin the gravitational collapse process that leads to the creation of new objects. Those two requirements led astronomers to suspect galaxy mergers and shock waves as two processes that can lead to starburst galaxies.à Centaurus A galaxy has a massive black hole at its heart that is actively gobbling up material. The actions of such active galactic nuclei may play a role in starbursts in galaxies. à ESO/WFI (Optical); MPIfR/ESO/APEX/A.Weiss et al. (Submillimetre); NASA/CXC/CfA/R.Kraft et al. (X-ray) Two other possibilities for the cause of starburst galaxies include: Active Galactic Nuclei (AGN): Virtually all galaxies contain a supermassive black hole in their core. Some galaxies appear to be in a state of high activity, where the central black hole is ejecting massive amounts of energy.à There is a great deal of evidence to show that the presence of such a black hole can dampen star formation activity. However, in the case of these so-called activeà galactic nuclei, they can also, under the right conditions, trigger rapid star formation as the accretion of matter in a disk and its eventual ejection away from the black hole can create shockwaves that could trigger star formation.High supernova rates: Supernovae are violent events. If the rate of explosions increases due to the presence of a very high number of aging stars in a compact area, the resulting shockwaves can begin a rapid increase in star formation. However, this such an event to occur the conditions would have to be ideal; more so than in the other possibilities listed here. A supernova can push clouds of nearby gas around spur limited amounts of starbirth. This supernova is shown in a Hubble Space Telescope view of the Crab Nebula supernova remnant. NASA/ESA/STScI Starburst galaxies remain an active area of investigation by astronomers. The more they find, the better scientists can describe the actual conditions that lead up to the bright bursts of star formation that populate these galaxies.à Edited and updated by Carolyn Collins Petersen.
