The Formation of Planet Earth

The Formation of Planet Earth The formation and evolution of planet Earth is a scientific detective story that has taken astronomers and planetary scientists a lot of research to figure out. Understanding our worlds formation process not only gives new insight into its structure and formation, but it also opens new windows of insight into the creation of planets around other stars.   The Story Begins Long Before Earth Existed Earth was not around at the beginning of the universe. In fact, very little of what we see in the cosmos today was around when the universe formed some 13.8 billion years ago. However, to get to Earth, its important to start at the beginning, when the universe was young. It all started out with only two elements: hydrogen and helium, and a small trace of lithium. The first stars formed out of the hydrogen that existed. Once that process started,  generations of stars were born in clouds of gas. As they aged, those stars created heavier elements in their cores, elements such as oxygen, silicon, iron, and others. When the first generations of stars died, they scattered those elements to space, which seeded the next generation of stars. Around some of those stars, the heavier elements formed planets. The Birth of the Solar System Gets a Kick-start Some five billion years ago, in a perfectly ordinary place in the galaxy, something happened. It might have been a supernova explosion pushing a lot of its heavy-element wreckage into a nearby cloud of hydrogen gas and interstellar dust. Or, it could have been the action of a passing star stirring up the cloud into a swirling mixture. Whatever the kick-start was, it pushed the cloud into action which eventually resulted in the birth of the solar system. The mixture grew hot and compressed under its own gravity. At its center, a protostellar object formed. It was young, hot, and glowing, but not yet a full star. Around it swirled a disk of the same material, which grew hotter and hotter as gravity and motion compressed the dust and rocks of the cloud together. The hot young protostar eventually turned on and began to fuse hydrogen to helium in its core. The Sun was born. The swirling hot disk was the cradle where Earth and its sister planets formed. It wasnt the first time such a planetary system was formed. In fact, astronomers can see just this sort of thing happening elsewhere in the universe. While the Sun grew in size and energy, beginning to ignite its nuclear fires, the hot disk slowly cooled. This took millions of years. During that time, the components of the disk began to freeze out into small dust-sized grains. Iron metal and compounds of silicon, magnesium, aluminum, and oxygen came out first in that fiery setting. Bits of these are preserved in chondrite meteorites, which are ancient materials from the solar nebula. Slowly these grains settled together and collected into clumps, then chunks, then boulders, and finally bodies called planetesimals large enough to exert their own gravity.   Earth Is Born in Fiery Collisions As time went by, planetesimals collided with other bodies and grew larger. As they did, the energy of each collision was tremendous. By the time they reached a hundred kilometers or so in size, planetesimal collisions were energetic enough to  melt and vaporize  much of the material involved. The rocks, iron, and other metals in these colliding worlds sorted themselves into layers. The dense iron settled in the center and the lighter rock separated into a mantle around the iron, in a miniature of Earth and the other inner planets today. Planetary scientists call this settling process  differentiation.  It didnt just happen with planets, but also occurred within the larger moons and  the largest asteroids. The iron meteorites that plunge to Earth from time to time come from collisions between these asteroids in the distant past.   At some point during this time, the Sun ignited. Although the Sun was only about two-thirds as bright as it is today, the process of ignition (the so-called T-Tauri phase) was energetic enough to blow away most of the gaseous part of the protoplanetary disk. The chunks, boulders, and planetesimals left behind continued to collect into a handful of large, stable bodies in well-spaced orbits. Earth was the third one of these, counting outward from the Sun. The process of accumulation and collision was violent and spectacular because the smaller pieces left huge craters on the larger ones. Studies of the other planets show  these impacts and the evidence is strong that they contributed to catastrophic conditions on the infant Earth.   At one point early in this process a very large planetesimal struck Earth an off-center blow and sprayed much of the young Earths rocky mantle into space. The planet got most of it back after a period of time, but some of it collected into a second planetesimal circling Earth. Those leftovers are thought to have been part of the Moons formation story. Volcanoes, Mountains, Tectonic Plates, and an Evolving Earth The oldest surviving rocks on Earth were laid down some five hundred million years after the planet first formed. It ​and other planets suffered through whats called the late heavy bombardment of the last stray planetesimals around four billion years ago). The ancient rocks have been dated by the uranium-lead method  and appear to be about 4.03 billion years old. Their mineral content and embedded gases show that there were volcanoes, continents, mountain ranges, oceans, and crustal plates on Earth in those days. Some slightly younger rocks (about 3.8 billion years old) show tantalizing evidence of life on the young planet. While the eons that followed were full of strange stories and far-reaching changes, by the time the first life did appear, Earths structure was well-formed and only its primordial atmosphere was being changed by the onset of life. The stage was set for the formation and spread of tiny microbes across the planet. Their evolution ultimately resulted in the modern life-bearing world still filled with mountains, oceans, and volcanoes that we know today.  Its a world that is constantly changing, with regions where continents are pulling apart and other places where new land is being formed. These actions affect not just the planet, but life on it. The evidence for the story of Earths formation and evolution is the result of patient evidence-collecting from meteorites and studies of the geology of the other planets. It also comes from analyses of very large bodies of geochemical data, astronomical studies of planet-forming regions around other stars, and decades of serious discussion among astronomers, geologists, planetary scientists, chemists, and biologists. The story of Earth is one of the most fascinating and complex scientific stories around, with plenty of evidence and understanding to back it up.   Updated and rewritten by Carolyn Collins Petersen.

Examining a Business Failure - Essay Example Two other recruitments to follow were that of Rebecca Mark and Jeff Skilling, both of whom were close accomplices of the CEO, and both of them strong enough to head new business lines of Enron. The CEO’s strong political back-up also helped the cause. While these new executives helped Enron spread its wings internationally into the energy market and energy financing, there was an unhealthy inter-personnel rivalry going on in the organization. The exit of Kinder as President fuelled the rivalry further, after Skilling was promoted as President of Enron. Mergers and acquisitions were a part of life at Enron, and soon the conglomerate, which started as a gas pipeline company, ventured into energy trading, and subsequently launched into new markets such as metals, paper, water and bandwidth. Enron was known as a â€Å"Takeover Tycoon† with a â€Å"Midas-touch†. However, most of these merger and acquisition decisions were taken not professionally, but for personal interests of the top executives who wanted to flex their own muscles within the organization to out power the other. Much to the surprise of the corporate world, the Enron ‘bubble’ burst in the year 2001, and investigations into this matter opened a can of worms, revealing that it was not only the Enron executives, but also the legal advisors, their accounting firm and security brokers were a part of the scandal. Keep a fair distance between political influence and business. Too much of political influence on business could prove hazardous. As for Enron’s case, their proximity to the political system helped them easily garner deregulations and other macro issues in their favor, much to the agony of the workers, pensioners and other stakeholders. Professional service providers such as that of accountants, lawyers, stock brokers, etc. should keep themselves away from ‘personal interests’ gained

ICD 9 to ICD 10 Regulations and Standards - Benefits and Challenges Article

ICD 9 to ICD 10 Regulations and Standards - Benefits and Challenges - Article Example It was first instituted in the mid 1970’s and is therefore almost forty years old. Along with being outdated, the codes for the older editions are at maximum capacity. Technically, the United States will be almost the last developed country to fully embrace ICD 10, as it had been in use in many countries since 1993. Actually it will be known in this country as ICD 10-CM, due to changes made to the version. The change from nine to ten was also necessitated by the increasing evolvement of informatics. Where edition nine can only utilize 13,600 volumes of code, ICD 10-CM can handle 69,000, an increase of over five hundred per cent (AAPC, 2012). Discussion Besides the added capacity of ICD 10-CM, there are various benefits it offers. First of all, part of the reason for the increased volume is the difference in the size of codes between the two. Nine has no more than five characters and is alpha numeric but only uses E or V (only in digit 1). ICD-10 has up to seven characters and is likewise alpha numeric but the difference is the alpha character can be any letter, first or last position. The Centers for Medicare and Medicaid Services (2010) defines the benefits (among others) as the ability to have a measurement device for care and efficiency, preventing public health risks (such as communicable diseases), streamlining payment devices, tracking and stopping fraud, and conducting policy and research. The attachments required by ICD-9 to diagnose a patient will also be greatly reduced in ten. With benefits of a new system there are also always challenges involved. First are the financial and resource liabilities payers will face for implementation, as it â€Å"will be a complex and painstaking process† (Thompson, 2011). Another problem for payers and health care staff alike is the training involved, both for the time constraints involved and moneys expended. Like Thompson points out however, training is tantamount, for health Workers entering the wrong codes could be disastrous and also result in delayed payments for their entity. Also, certain private payers such as Workmen’s Comp insurers are not required to transition to ICD 10-CM. So providers will have to face the economic and logistical nightmare of operating two different versions. Actually Kathleen Sebelius, the Secretary of US Department of Health and Human Services (HHS) announced earlier this year that the deadline for ICD 10-CM has been extended for one year, until October 1, 2014. So hospitals have some breathing room. Cumberland Consulting Group specializes in helping healthcare facilities employ new technologies such as ICD 10-CM. Their Amanda Brenegan in an unbiased report on ten (Herman, 2012) points out over forty per cent of hospitals at least have a plan of implementation and many have already started the laborious process of training physicians and staff. However, she is critical in stating that the training is probably lacking, as most trainees donâ⠂¬â„¢t understand the concept of ICD 10-CM. Another hurdle facing hospitals is having to undergo too many transitions at once. Electronic Health Records (EHR) has already surpassed its October 3, 2012 deadline for incentive payments due to early implementation. In February of this year the National Institutes of Health (NIH) published a roadmap to help with the interaction of ICD 10-CM and the Systematized Nomenclature of Medicine-Clinical Terms (SNOMED CT), which had been adopted by eighteen countries, including the US, Australia and Denmark.

How Modern Medical Technology is Easing Out Standard Physical Examination Essay Example for Free

How Modern Medical Technology is Easing Out Standard Physical Examination Essay In today’s time-constrained society, medical practitioners are noticeably turning to modern technology to pinpoint health problems of patients. Most new-generation doctors who rely a great deal on sophisticated machines in ascertaining medical issues faced by their patients illustrate a startling reality: the standard physical examination stands to be eased out. While science has made possible quicker, more convenient, and non-invasive ways of spotting and treating health disorders, being overly dependent on technology has its drawbacks. The problem with technology arises when doctors rush to order tests without first performing a thorough physical exam†¦ Doctors may be overly reliant on tests because they have confidence in the results; however, tests aren’t always accurate† (Max, 2009, par. 6). A seemingly better approach that redounds to patient benefit is the combination of modern technology with age-old practices that worked, notably a thorough physical examination done prior to tests or possible confinement and as part of the doctor’s hospital rounds. There are several factors contributing to the demise or exclusion of the standard physical examination in modern medical practice. For one, there is the shortage of medical personnel in certain localities. Harried doctors and nurses end up employing measures to maximize time. â€Å"Time constraints also discourage performing a complete physical during routine office visits. The managed care system pushes doctors to see patients as briefly as possible† (Obel, 2003, par. 6). The fact is that the physical examination â€Å"can be a valuable guide in deciding which tests to order and letting specialists know where to concentrate their efforts† (Obel, 2003, par. 7). Hence, the standard physical examination can greatly aid doctors in ruling out certain health issues, thereby saving time and money on unnecessary tests. However, new-generation doctors overlook these, believing that using sophisticated equipment is more effective in reaching an accurate medical analysis than conventional routine practices. Indeed, a professional diagnosis relying first and foremost on the standard physical examination appears to have been displaced by modern devices. The downside is the loss of human contact that most patients may still prefer. â€Å"There is an intangible benefit to the contact afforded by the physical exam†¦(it) can go a long way in establishing and building a good doctor-patient relationship† (Max, 2009, par. 11), something which most patients – from the very young to the elderly – yearn for. The emotional bonding between the healthcare giver and the patient is obliterated with less time allocated to examine patients. As seasoned medical practitioners decry the demise of the physical examination, which â€Å"can be therapeutic in itself† (Obel, 2003, par. 35), concerned medical institutions have instigated efforts to train and retrain medical interns on the vast range of medical approaches – including the routine physical examination. The increasingly important role of nurses, who can assume the vital task of resuscitating the fading practice of conducting a thorough physical examination and promoting human interaction, cannot be underestimated. Well-trained nurses who realize the value of human interaction can play significant role in fostering enhanced patient care and faster recovery. The upsurge in electronic technology users is another phenomenon affecting the demise of face-to-face interaction with physicians and the traditional physical examination. With many doctors nowadays dispensing medical advice online by relying purely on patient history and description of symptoms, thereby eliminating the need for a comprehensive physical examination, it becomes clear that modern trends are taking the place of traditional medical approaches. The inescapable fact is that medical practitioners cannot always totally rely on modern technology alone to ascertain patient needs. Even in modern times, there is a need to go back to basics, ingrain patient-oriented skills among the emerging crop of doctors, and revive conventional medical approaches like the physical examination.

Gun Control Essay -- Second Amendment The Right To Bear Arms

â€Å"A well-regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.† Does our second amendment really give rights to civilians to carry guns, which are a mechanical device that expels a bullet which can accurately travel colossal distances? As the U.S. sees it today, guns are legal to anyone who fits their criteria. Guns have been used for hundreds of years in the history of our world and nation. However, gun control has been a major debating issue during the past few decades. On one side, there are those who completely agree with the control laws and on the other there are those who oppose gun control laws all together. Gun control opponents provide many justifications for carrying a gun, such as the second amendment, self-defense, hunting, or target practice.   Ã‚  Ã‚  Ã‚  Ã‚  Guns are not for everyone. Certain individuals cannot handle a firearm safely, and some individuals choose to use firearms unsuitably. Our society has passed laws regulating the possession and use of firearms, and more legislation is being considered. Most of this legislation restricts, to some degree, the rights of individuals to possess or use firearms. â€Å"Some limitations may be necessary, but some modern legislation has gone too far. Society benefits from firearms in the hands of conscientious citizens. Attempts to keep firearms away from these citizens do more harm than good.† (stated by the NRA)   ...

Musical Instruments Speech Essay

The Chinese philosopher Confucius said long ago that â€Å"Music produces a kind of pleasure which human nature cannot do without. † Being able to play any musical instrument is extremely satisfying. This includes everyone from the person who has mastered her instrument right down to the beginner who knows only a few chords. I personally believe that if there’s one thing you should learn in your lifetime, it’s how to play an instrument. Learning to play a musical instrument offers a lot of benefits and can bring joy to you and to everyone around you.. Here the four most important benefits of playing instruments: The first benefits, is that playing a musical instrument makes you smarter. Playing an instrument helps the mind to be alert and remain active eventually helping to sharpen the memory. Learning an instrument requires you to learn about tones and scores which increase your ability to store audio information. According to an article from The Telegraph online magazine, â€Å"New research suggests that regularly playing an instrument changes the shape and power of the brain and may be used in therapy to improve cognitive skills. There is continually more evidence that musicians have organizationally and functionally different brains compared to non-musicians, especially in the areas of the brain used in processing and playing music. These parts of the brain that control motor skills, hearing, storing audio information and memory become larger and more active when a person learns how to play an instrument and can apparently improve day to day actions such as being alert, planning and emotional perception. And according to Lutz Jancke, a psychologist at the University of Zurich, said: â€Å"Learning to play a musical instrument has definite benefits and can increase IQ by seven points, in both children and adults. † For children especially we found that learning to play the piano for instance teaches them to be more self-disciplined, more attentive and better at planning. All of these things are very important for academic performance, so can therefore make a child brighter. The second benefits, is that playing a musical instruments relieves stress. Playing any instrument can actually help release the endorphins in your body, which will also result in reduced levels of stress Playing music naturally can soothe not only others, but the musician as well, not only the actual sound of the instrument, but also the release of creativity and emotion, as well as the simple vibration of an instrument against a player’s body can significantly lower a musician’s stress level.. The study’s principal investigator, Barry Bittman, M. D. f the Mind-Body Wellness Center in Meadville, PA, says these unique findings not only shed new light on the value of active music participation, but also extend our understanding of individualized human biological stress responses on an unprecedented level. Most people would be very surprised at just how easily their stress and problems can be forgotten while playing their instrument on a quiet evening. There are no pressures or expectations while playing. This creates a perfect environment for relieving stress, along with the joy and relaxation of listening to your own musical creations. The third benefits, is that playing musical instruments enhances an individual’s ability to recognize emotion in sound. The musicians had a heightened response to the complex portion of the sound, where the frequency rapidly changes. When the musicians heard the simple sections of the sound they had lower responses. Musicians showed enhanced responses to the most acoustically complex portion of the stimulus and decreased activity to the more periodic, less complex portion. the musicians conserve neural resources while processing simpler sounds (economy) and deploy them to more thoroughly respond to complex sounds (enhancement). The study found that the more years of musical training and the earlier the age in which the musical studies began, the more enhanced their nervous systems were to process emotion in sound. Historically, it has been thought that the auditory brainstem is fixed, that information flows through without changing any of the circuits. According to Kraus’ research shows that it is not only trainable, but more malleable than previously thought. Scientists know that emotion is carried less by the linguistic meanings of words than by the way the sound is communicated. Kraus’ work reveals that brain changes involved in playing a musical instrument enhance one’s ability to detect subtle emotional cues in conversation. And last most important benefits of playing instruments, is that playing a musical instrument is fun. Everybody enjoys hearing music, but the people who make the music have the most fun. Once you get better playing your chosen musical instrument, you will be able to demonstrate what you have been learn to your families and friends that gives you fun and enjoyment. The songwriter Bob Dylan has written numerous well-known songs using only a few chords. There is nothing like the feeling of suddenly walking into a room and playing a song you just learned or wrote for a friend. You don’t have to be Beethoven to appreciate the benefits. And it is nothing but fun to sit down with a couple of friends and play and sing a song. In this camaraderie there is an endless amount of discovery and laughs to be had. The sound you’re making rises and falls, singing in the voice of the instrument. But it’s not really the instrument that’s making those great sounds—it’s you! It’s fun, even when you play by yourself. Playing in a group is even better because other players are sharing the fun. There’s no way to have all that fun than for you to be the person who is playing the music! As you can see, playing a musical instrument has many benefits and hopefully that will motivate you to keep on practicing and always hold music in high esteem. Whenever you come across challenges as a musician, think about the end results and always remind yourself of all the great reasons you love to play. I’ll leave you with an inspiring quote by jazz saxophonist and composer Charlie Parker who once said, â€Å"Music is your own experience, your thoughts, your wisdom. If you don’t live it, it won’t come out of your horn. †

Feminist Criticism By Lois Tyson - 2072 Words

It is difficult to imagine living in a world without the patriarchal roles that are present in society and have been throughout history. In the article â€Å"Feminist Criticism,† by Lois Tyson, the idea of feminism and how society has affected feminism is the focus. These ideas are seen because men have more of a voice in nearly everything and the oppression of women is very common; a society set up like this can be described with the term patriarchy which is â€Å"any culture that privileges men by promoting traditional gender roles,† where men are cast as â€Å"rational, strong, protective, and decisive,† and women are cast â€Å"as emotional, weak, nurturing, and submissive† (Tyson, 1). This thought that men are strong and women weak is not uncommon in†¦show more content†¦Daisy Miller is breaking these social norms by constantly associating with different men, drawing the attention of many others and Connie expresses her sexuality by abandonin g her friends to spend time with a boy in his car; this ultimately leads to society’s metaphorical murder of these women. Daisy is an American teen who is traveling Europe and spends lots of time with men in an 1800s European society that frowns upon these actions and ultimately punishes her for them. Winterbourne is a man who is infatuated with Daisy due to her beauty and although he knows it isn’t proper to interact with Daisy without a chaperone present, he talks to her anyways and â€Å"was ceasing to be embarrassed, for he had begun to perceive that she was not in the least embarrassed herself. There had not been the slightest alteration in her charming complexion; she was evidently neither offended neither fluttered† (James, 6). The first time that Winterbourne has a conversation with Daisy he had expected it to be under the supervision of another person. Because Daisy is not used to having to do this she isn’t phased and continues the conversation with Winterbourne. This doesn’t make Winterbourne mad, but instead makes him more attracted to Daisy.
