Meteorites Evidence in Support of Solar Nebular Hypothesis Research Paper

Meteorites Evidence in Support of Solar Nebular Hypothesis - Research Paper Example This theory has been widely accepted because it is thought to provide a worthwhile explanation of the orbital properties of the solar system and the way planets orbit less or more in the same plane (Abruzzo 44). According to this theory, originally, there existed a big cloud of gas and dust, which became unstable, probably because of the shock waves originating from the nearby density waves or supernova. The part of the cloud, which was the densest begun collapsing under the force of gravity. This force of gravity, then pulled the gas and dust towards the center point of the cloud. The cloud was forced to take a spherical shape, thereby becoming a protostar. Increased centrifugal force or rotation of gas and dust caused this cloud to form a flattened shape or accretion disk around it (Abruzzo 46). According to this hypothesis, this explains why the rotating disk if gas and dust is solar Nebula. A number of studies have sought to confirm this hypothesis, however, the practically of th is hypothesis has never been illustrated as it has been illustrated in the American Museum of national History (AMHH). American Museum of Natural History (AMNH) has been one of the world prominent scientific institutions, known for its exhibitions and collections, which illuminate of the Earths evolutions, right from the origin of the present planet to its present form. AMNH is New York Icon. I have always wondered how everything came into being. The mystery of life and therein has been a closely contested subject. Besides, it has always been my dream to visit AMNH and learn of the scientific evidence located in meteorites supports Solar Nebula Hypothesis. Recently, I made my way into the AMNH. The Museum is located at Central park West on the 79th Street and is easily accessed by public transport. Driving to the museum, I got inclined to give a benefit of doubt, though I had no basic grasp of the real evidence for the Solar Nebular Hypothesis. The main entrance to the Rose Center for Earth and Space is situated at 81st Street between the Columbus Avenue and Central Park West. Although I have a perso nal car, I chose public transport perhaps to evade the huge parking fees. When I arrived at 10 am, I was surprised to find many uniformed police at the entrance, directing traffic. The heavy police presence depicted the 9-11post security situations. Perhaps, this shows the importance of the structure under close security. I marveled at the structure  it was huge yet with a modern style. While, at the museum, I sought direction to the Arthur Ross Hall of Meteorites. The hall is situated on the far end of the AMNH bordering Sacker Educational library to the south and The Hall of Minerals to the East. First, we watched a movie in the Meteorite Theater, located in the Hall along the Planet Wall display. The movie was breathtaking. It brought into perspective the events that took place million years ago. In essence, the film presented the role of meteorites and their connectedness to the history of the solar system. This offered a solid foundation for the understanding of the concepts later presented in the exhibition. I came across one of this displays which stated that meteorite were rocks from space, which had survived their passage in the universe to land to the surface of the Earth. Some meteorites, are often heard or seen, when they fall and are collected afterwards while other are discovered later. The size of meteorites varies, in that some are large to cause craters upon falling while others are small and one need a help magnifying equipments to vie them. They take different forms, where some resemble igneous rocks, and others are metals. Despite their variation in terms of appearance, size, and manner of discovery, they are all pieces of different bodies in space,

Importance of Prayer Essay Example for Free

Importance of Prayer Essay An uncontrolled mind cannot progress in spiritual path unless it discovers the Self. The discovery of the Self is possible by self-control achieved through the withdrawal of sense organs from their respective objects. Yoga can be attained by striving hard to utilize the conserved energies for the Divine purposes. Yoga is the science of religion. Meditation is said to be the best among all the paths of spirituality. Meditation is a deliberate act by which the seeker strives to keep his thoughts channelized into one pre-determined line of thinking by not allowing the mind to entertain any other thoughts. It is therefore an attempt to fix the mind upon some object of contemplation. The Bhagavad Gita elucidates meditation as the final gateway to Self-realization. Renunciation is not giving up enjoyments, abandoning one’s duties and escaping to a safe sanctuary. It is this misunderstanding that has turned away genuine seekers and prevented them from accessing the benefits of renunciation. The Yogi whose mind is harmonized will see the Self in all beings and all beings in the Self. He never becomes separate from The Lord nor does The Lord become separated from him. The perfected saint acts as an instrument in the hands of God. The mind must be made to rest in God. When the mind is restrained by the practice of meditation, it realizes the Self within. It experiences such Bliss as if there is nothing else in the three worlds worth possessing. When the mind is directed towards God, with a comprehensive understanding, ones perception, attitude and desires for the world change automatically. On realizing the Self even the taste for the sense-objects ceases. Thus by experiencing the God-consciousness through continuous meditation one perceives the Unity in Diversity when all the desires come to an end. Arjuna, like us, is afraid of leaving the safe confines of his present existence to discover the unknown realm of the Infinite. He asks Krishna what would be the fate of those who commit themselves to a spiritual life but die before realization. Krishna gives a fitting reply to reveal one of the most insightful laws of life. He says, â€Å"One who is righteous will never come to grief – either now or in the future. His efforts will not go in vain. He will carry forward the credits to his future life†. Hence Live ND PRACTISE as the Gita Teaches us to Live Meditationneeds to be practiced diligently and devotedly. The essential prerequisite is a calm mind. A mind burdened with desires and attachments is unable to take off into subtler realms of concentration and meditation. Yoga brings about a disciplined mind. This can be brought about by curtailing the outgoing tendencies of the mind. It leads to bliss. Once the state of bliss is reached, all other worldly matters lose their influence over the body and mind. Such a man will feel his oneness with God. He will experience unity in diversity. Any effort towards meditation is not wasted. Raise yourself by yourself. Know what meditation is and practice it regularly. Be moderate in everything you do.

Conan Doyle´s The Speckled Band vs Visitor´s by Brian Moon Essay

  Ã‚  Ã‚  Ã‚  Ã‚  This essay will examine both "The Speckled Band" by Conan Doyle and "Visitors" by Brian Moon and will look at how each one conforms to or diverges from the conventions of the detective story and also how each story is representative of the century it was written in by how it presents the woman, the hero and the villain.   Ã‚  Ã‚  Ã‚  Ã‚  The conventions of the detective story were mostly established in the early twentieth century yet "The Speckled Band" was written in the late nineteenth century. However, it still conforms to most of the detective story conventions, therefore I conclude that it deserves to be called a detective story   Ã‚  Ã‚  Ã‚  Ã‚   One of the conventions of the detective story is that the detective if frequently an amateur. In "The Speckled Band" Holmes does not work for any official body, like the police, for example. He is not, however, an amateur in the sense that he solves crimes for a hobby, he says, â€Å"as to my reward, my profession is my reward.'; Holmes is an amateur in the root sense of the word â€Å"someone who works simply for the love of it'; However the way that Holmes uses the word â€Å"profession'; shows that he does not consider himself to be an amateur.   Ã‚  Ã‚  Ã‚  Ã‚  Another convention of the detective story is that the detective will have a confidant through whom he can explain his reasoning to the reader. Holmes has a confidant, Watson, who is the stereotypical gentle doctor who is plain and uninteresting so as not to draw attention away from Holmes. â€Å"I had no keener pleasure than in following Holmes in his professional investigations'; this implies that Watson lead an uninteresting life, without many interesting hobbies or pastimes.   Ã‚  Ã‚  Ã‚  Ã‚  Another convention of the detective story is that the detective is in competition with the police, however, in "The Speckled Band" Holmes is not in competition with the police. Holmes does, however, express his disgust with the official police force â€Å" fancy his having the insolence to confound me with the official detective force'; this line shows that Holmes considers the police force to be incompetent and ineffective.   Ã‚  Ã‚  Ã‚  Ã‚  A convention of the detective story is that it has a variety of suspects for the detective to choose between, "The Speckled Band", however, does not have many suspects, only Dr Roylott and the gypsies. Roylott is a suspect for the murder as he is violent â€Å"uncontrollable in his anger'; and the local... ...tray a hero and a criminal, the difference is that in ‘The Speckled Band’ they are different people while in ‘Visitors’ they are arguably the same person. In ‘Visitors’ the police are expected to act the heroic role but don’t look or sound the part, in this way ‘Visitors’ appears not only to fail to comply with the conventions but also to be a paradoxical story.   Ã‚  Ã‚  Ã‚  Ã‚  My essay has shown that both stories conform to a certain extent to the conventions of the detective story. Both show views of the woman, hero and villain, and in ‘The Speckled Band’ this highlights the complacent, satisfied attitude of the Victorians, while ‘Visitors’ shows the less complacent, worried, changing attitude of the late twentieth century, influenced by the social devastation of two world wars.   Ã‚  Ã‚  Ã‚  Ã‚  After looking at ‘Visitors’ and ‘The Speckled Band’ I have come to the conclusion that ‘Visitors’ does not really deserve to be called a detective story as it does not really have a detective in it or even a crime to solve, however I still think that ‘Visitors’ is an exceptional story in its own right and a better story than ‘The Speckled Band’ because of how the important issues it brings up are dealt with.

A Sympathetic Antonio in Hector Tobar’s The Tattooed Soldier

A Sympathetic Antonio in Hector Tobar's The Tattooed Soldier BY ant28 Sympathetic Antonio In Hector Tobar's novel, The Tattooed Soldier, many of the characters experience unpleasant situations. These include homelessness, Joblessness, and murder. These unpleasant situations lead to negativity in their lives, and this negativity can evoke feelings of sympathy. Of all the characters in Tobar's novel, I believe Antonio deserves the greatest amount of sympathy because he lives a life of constant despair and is often treated unfairly, which is like a trap from which he cannot escape.Antonio's wife and son, Elena and Carlos, are killed by Longoria. In the chapter, Fire Escape†, on page 183, it states â€Å"l did not bury my wife and child, but I can stand and seek vengeance, for them and for the many, for the anonymous dead†. â€Å"Now Antonio knew how Elena must have felt when she marched in the demonstrations. Now he could see why she was a revolutionary, he could understan d what had been a mystery before†. â€Å"This is how Elena felt, tall and strong. This is what she was trying to tell me, but I wouldn't listen. Elena knew that to march with the many was to stand tall.Elena loved me because she knew I could be a brave fghter† (Tobar 183). This shows that Antonio is upset because his wife Elena and his son Carlitos are killed. Elena had written a complaint letter to the government because people were dying due to the filthy water caused by the garbage that people dumped onto it. She requested that the changes should be made in a nearby city. She was also famous for making her points clear. The Guatemalan government sent a soldier named Longoria to kill Antonio and Elena for complaining to the fascist government and they found it to be a threat.Their family have been suspected of being informer immigrants and are being hunted down. Antonio escaped death by being at work when his family was killed. After the death of his wife, Antonio had no choice but to escape from there if he wanted to live. He ran away to Los Angeles, hoping for a better life. Instead, Just the opposite occurred. Antonio felt sad due to the fact he was facing many hardships and has difficulties living. In Los Angeles, Antonio saw poverty and despair everywhere he went He was poor, had no Job, and no home. He became homeless because he was an immigrant.Antonio was an immigrant who didn't know that much English. He used to be a middle class government worker in Guatemala. When Antonio came to Los Angeles, everything he knew became useless. It was like this for him since he couldn't communicate and he had to accept any Job that would help him earn money. He had to be in this situation if he did not want to be killed. He was living in a hotel but eventually he got kicked out of it and had to go live on the streets. In the chapter, â€Å"Fire Escape†, on page 183, it states that â€Å"Antonio would stay in Los Angeles and track down the tatto oed soldier and make him pay for his crimes.He would kill this man with his own hands† ( Tobar 183). In the chapter, Department of Sanitation, on page 228, it states that â€Å"l have been living this way, less than human, for longer than I can remember. I have been wearing the helmet of mourning and self-pity too long. I am living in the streets, under the starless sky. I am homeless† (Tobar 22 In the chapter, â€Å"Department ot Sanitation†, on page states that â€Å"there is a balance between us. We are opposites balancing a scale, we are mathematics. I am tall, he is short. I live under the sky, he lives under the roof.He as a girlfriend, I live alone. He has a Job, I do not. He is the killer, I am his victim. † (Tobar 229). In the chapter, Department of Sanitation, on page 232, â€Å"it also states â€Å"In a matter of moments their shelter had been reduced to a tidy patch of dirt. After the police left, after he had listened to their final warning to â€Å"stay off this property', Antonio went back to the lot and examined the ground, walking slowly in a growing spiral. There was nothing to be found but the bumpy soil beneath his feet, the crisscross of the bulldozer's long tracks, the wounds gouged by the shovel† (Tobar 32).These are the three ways it shows that he is facing poverty and despair. Homelessness is why Antonio became the man he is. Antonio felt as if he had really lost everything. He had lost the family he had, his life in Guatemala, and now his apartment in Los Angeles. Antonio felt that being on the streets downtown made him feel braver than he had ever felt because he made choices that he most likely would never have made if he lived in his old apartment in Los Angeles. Antonio lets out his anger on an elderly man who attempts to steal a hot plate pan from a large trash bag f their belongings from his old apartment.Antonio runs after the old man and punches him multiple times. â€Å"Antonio drove his f ist into the man's face, the nose cartilage snapping under his knuckles. Another punch this one like hammering nails into the ground, a clenched fist to the temple. A weak scream from the thief, and then one more punch, to the mouth†. He felt ashamed and embarrassed of what he did to the old man, unlike Longoria who feels more alive after his savage acts. Antonio eventually blames his actions on the surroundings. Antonio becomes determined to ill Longoria and begins to watch Longoria's every move.He has the desire to kill Longoria for many reasons and wants to get rid of him. Eventually, under many conditions, Antonio does manage to meet Frank, another homeless man who is an African American on the streets of Los Angeles. As they both move from place to place, they spot Longoria. This sighting evokes feelings of sadness in Antonio, and asks Frank to help him get revenge. Frank is hesitant at first to assist Antonio but then does because he hears that Longoria can be similar to a Nazi, and doesn't think again and offers to help.Just a few feet from the soldier, he raised the pipe in the air, lifting his arms and rotating his shoulders like a baseball pitcher in his windup, gathering a wave of strength in his muscles to kill the man once and for all, to rid the earth of him(Tobar 208). This is because Antonio came into his anger and tried to attack Longoria while he is at the park, playing chess with his friends. Antonio felt that he made his extinct baby and wife proud of him by doing this revenge. He also purchased a gun to ensure himself that he would take the life of Longoria and make no mistakes while doing so.

Network 240 Linux Comparison

Outline There are a quite a few Linux distributions available that address a variety of functionalities within the operating system ( OS ). There are many factors to consider when deciding which Linux vendor to use and what distribution will suit your needs. According to DistroWatch there are 322 active distributions available in the database. The basic difference between the desktop version and the server version is the presence of a graphical user interface ( GUI ). This paper will provide basic information on Knoppix, list the top ten Linux distributions, and provide a comparison of Ubuntu, Red Hat, and Fedora.Knoppix is an ideal option for new users. Knoppix is a low maintenance distribution that allows an individual to boot directly from a CD in order to sample the Linux environment. The user can run several different software applications and save files. More importantly, because Knoppix can be booted from a CD no actual installation takes place so there is no interruption with the existing operating system ( OS ). Ubuntu is one of the most popular versions of Linux and very user friendly.The Ubuntu desktop version comes with three years of support, a graphical user interface ( GUI ) and the following applications installed: X, Gnome, and KDE. The server version does not utilize a graphical user interface ( GUI ) and relies on the end user utilizing the command line interface ( CLI ). The server version comes with Apache Web Server 2 and Bind 9. Red Hat Enterprise Linux was formally known as Novell Linux Desktop. Redhat offers a combination options to address end user needs, but concentrated in the server area. The server side offers two 9 2 ) or four ( 4 ) socket server options and the use of virtual guests.Redhat Enterprise Desktop utilizes a layered defense system, plug-n-play support, is bundled with popular applications, which are interoperable with Microsoft counterparts. Fedora appears to be one of the more flexible versions. Fedora is an open proj ect for Redhat and allows the end user to customize the installation and choose which services and applications to install. This feature allows users to choose exactly what is needed during installation to address their needs and is targeted for at home users.
