“How the Earth was Formed” video notes Essay

Theory: -sun was surrounded by a cloud of dust and gas -as cloud cooled little grains of minerals started forming -grains of minerals started bumping into each other (Problem was nobody could explain how these microscopic minerals formed a planet) Then in 2003 astronaut Don Pettit performed an experiment onboard the international space station. He put some salt in a plastic bag and found that almost immediately the grains started gathering together into little clumps held together by static charge. -These mineral grains grew into small pieces of rock orbiting the sun -over the next few million years some of these rocks collided and grew bigger -when a rock grew to become around half a mile across, its gravitational pull became strong enough to pull objects towards it. (The bigger the rock was the faster it grew because it had higher gravitational pull) -so that biggest rock eventually grew to become ‘the fledgling earth’ -soon this small planet grew to attract even bigger objects that collided with its surface, every impact only served to increase its size. -The collisions were so intense it only (lol) took about 30 million years for the planet to grow to (approximately) its present size. Presently, the earth is separated into three layers: A thin crust, then a massive dense layer of rock called the mantle, and an iron and nickel core. -So then this big rock became so hot that it melted and the denser materials drifted to the core while the lighter materials floated at the top -the heating up of fledgling earth could have been due to the incorporation of very hot radioactive elements. -The temperature of molten earth was now 2000 degrees, but at the edge of the planet the temperature of space was a constant -450 degrees, almost 2  ½ thousand degrees colder. -So because of this the surface could not stay molten forever -then in about a million years the earth had its thin crust, but volcanoes still erupted and meteorites still showered the surface Physicist Ernest Rutherford discovered that measuring radioactive decay could accurately measure the age of rocks. Soon after this rocks from around the globe were found to be billions of years old. The meteor that hit in the crater in Arizona landed with the force of a two-mega ton atomic bomb. The explosion vaporized most  of the meteorite, but individual fragments survive. Patterson took some samples, dated them, and found that they were around 4.5 billion years old. A recent study estimates the earth to be around 4 billion 567 million years old Theory of how the moon was formed: (1974) in the early solar system there were dozens of small planets chaotically orbiting the sun, one of them was on a collision course with earth. When it collided with the earth it blew some of its crustal/mantle rock off and within a few thousand years that debris formed the moon. (The other small planet was destroyed in the collision.) Rocks at Porpoise Cove in Canada are highly altered deformed volcanic lavas called amphibolite. They are 4.28 billion years old, 200 million years older than any rocks so far discovered and the closest anyone has come to earth’s original crust. These amphibolites give us clues about the thickness of the earth’s early crust. O’Neill has found minerals that are unusual and can only form under high temperatures and pressures which proves that these rocks formed at least 12 miles into the crust of the earth, which tells us that just over 4 billion years ago the earth’s crust was about 12 miles thick. The chemical signature of amphibolite indicates that 4 billion years ago, earth had both a solid crust and oceans. (because amphibolite is similar to the ocean floor or something like that) Banded iron formations: made up of alternating light layers of silica and dark bands full of a mineral called magnetite. These bands full of magnetite only form underwater, further proving that oceans existed 4 billion years ago. How water came to be on earth: Grains of table salt found in meteorites that fell to earth carry tiny droplets of water. Over the billions of years in which the earth was formed, these droplets added up and became the oceans, etc. 3.5 billion years ago there was no oxygen, the air was a mixture of sulfur, methane, carbon dioxide, and sulfuric acid. But primitive life forms did exist, the fossilized remains of coral like structures have been found in rocks that are of that age. They are called stromatolites. They are made up of billions of microbes called cyanobacteria, which produce oxygen. At this time oxygen was poisonous to other life forms, which used sulfur to obtain energy. Over time there was enough cyanobacteria to produce trillion of tons of oxygen, creating the atmosphere we breathe today. Over 100s of millions of years, decaying plant matter built up compressed layers, which eventually formed all the coal, oil, and gas deposits on the planet.  Sedimentary rocks like lime stone and chalk are largely made from the skeletons of marine animals, which accumulated at the bottom of shallow seas.

Final Act of the play Essay

Secondly Elizabeth made a sacrifice, and really showed by doing this how much she respects John Proctor as her husband. When it came to the question itself, whether John was a lecher, she waited a while before she came to a final decision as she had no idea what to say, not knowing what her husband had stated before her. Constantly looking for a sign from john across the court having no clue what he had said before her. She was nervous, but was forced to answer the question and make that final decision: She replied faintly ‘No, sir’. This answer really shows the audience how strong her love is for proctor, lying for him to save his life, doing this against her religion, condemning herself to hell however this was a choice between either her husband or her religion and chosen her husband shows how strongly she feels about him. From what she believed he had lied to but they were both court out.  Act Four is considered to be a very emotional scene and is really shown by Miller himself. The events which occur in this scene are considered gruesome and drastic and have various reactions from different characters, but mainly Elizabeth and John’s relationship and how it dramatically changes and gradually pulls together in the final Act of the play. The day in which act four starts Elizabeth is aware John is going to be hanged, and clearly states that no emotion is shown towards him, especially when talking to Dan forth about it before speaking to proctor himself. She shows this coldness, relating back to the first two scenes and makes it seem as though she’s not going to let them win against her, making it very hard for her as really underneath she knows in fact her husband is about to die before her very own eyes and there’s nothing she can do to save him, and she wants to follow what she think john would have wanted her to do for him or if he were in her shoes. Having Elizabeth and Proctor apart from each other for a period of time whilst she was taken to Salem must be hard for them as they both haven’t as of yet spoken at all to each other about what has happened. This proves to the audience there a large amount of emotion between them both which a real change from Act two were emotion between them was very low and Elizabeth’s thoughts toward Proctor weren’t anything to what they are now. Miller really uses this scene to stun the audience when seeing the couple starring into each others eyes with such needed love and emotion really showing how there relationship is some what different to before. The first thing that is stated when the conversation begins with john is ‘the child’ which straight away takes us back to the first conversation they had in act two were the general talk was about there children. The conversation continues but sentences and phrases are very short, showing a real awkward atmosphere between them which is acceptable seeing as though they haven’t spoken or even seen each other in so long. The conversation carries on and they begin to open up to each other, there speech becoming longer and idea’s coming out, such as whether john should now confess or not? Finally there reaches a point were they are coming to terms with the truth and Elizabeth and john except the fact they have ‘known each other’ deeply and that fact he can end his life knowing she was always there to support him. This is were Act four is drawing to an end, were john lifts Elizabeth and kisses her with great passion which clearly states there relationship has come together, and changed so much from act two were john kissing Elizabeth was seen as such disappointment to her but no such a romantic and emotional moment. However its not just Elizabeth feeling this passion, they both share such moment together, letting the audience really no what they both want. After this passionate moment takes place, john is taken off the scene to be hanged, and Elizabeth is there to say her last few words to support her husband’s tragic death. Elizabeth seems glad he can finally be at peace as before his life seemed always troubled and never settled. He only really had one fault that he had made in his life and that was the affair with Abigail, and from she believed was that it was because of her, this shows her true feelings for there relationship and faulting herself makes her feel that little bit better. Throughout the whole play Author Miller presents the couple in many different ways, changing the way there relationship occurs in each scene, taking both different personalities into perspective. From act two were the relationship between them both was extremely tense and uncomfortable at times around each other, but progressively throughout the play, even when times got really tough there relationship seemed to get stronger and closer, showing that when times got tough they were actually there when they needed somebody to be with them and help the through it, this really shows how all along the couple have never fallen out of love and have always had such deep feelings for each other and meant for each other and this can especially be seen in act four when there relationship had to end due to the death of john Proctor.

Apple Customer Based Analysis Essay

Apple’s brand name has a very highly valued name in society. As an American, it is common for people of all ages and demographics to be a customer of Apple. It is prestigious yet also almost considered the normal in today’s society to have an Apple iPhone, Apple iPad, Apple iPod, or Apple Macbook. Society values Apple as having a high quality product that consumers can rely on but this also comes at a price. Most customers of Apple are just below the baby boomer generation with users as young as toddlers. Some parents may allow their toddler’s to use applications on their Ipads for their toddlers to learn and play games. Other demographics include all different races and both males and females. Apple prides themselves with easy to user consumer friendly technological products that people of all ages can use. Normally electronic products are focused towards the males however the Apple products have a significant female customer base as well. Apple products are normally sold in high income countries due to the high cost of the products. Apple products are not necessity products by any means and therefore apple customers have discretionary income to buy luxury goods such as the products that Apple offers. However, a music and video system such as Itunes may be more affordable for some consumers that use computers, phones, and tablets from other companies yet they can still download media from the Apple Itunes company. Middle class families in the U.S. can own Apple products but it may be a luxury item that the household saves for. Apple, as a technology based company naturally attracts customers that are looking for high quality up to date products that fit in with society yet are customizable and satisfy all of their customers’ needs. Apple’s Itune’s has legal rights to protect their media through patents and other legal rights that protect their electronic products. There is a current lawsuit between Samsung and Apple in which Apple claims that â€Å"the Galaxy S4, Samsung’s flagship smartphone violates five of its patents† (Zeman 2013). Therefore, this shows that Apple takes their patent and products very seriously and will follow up with a lawsuit if any of their competitors take any of their legal rights. Apple collaborates with many different companies in order to optimize their services and products including Microsoft. An Apple employee noted that â€Å"the company will now be organized by function- marketing, legal, business development etc.—with more collaboration across divisions† regarding Microsoft (Shaer, 2013). Apple also works with companies regarding the development of applications for their Iphone and Ipad products. There are many competitors of Apple such as manufacturers of PCs, tablets, cell phones, computer monitors, TVs, and many other types of electronics. These companies may consider Apple their largest competition but the one disadvantage that Apple has over other products is their higher price for their premium products. Due to the amount of competition it is very important that Apple continues update their products and marketing in order to remain in the market. Apple products can be purchased directly through Apple through the telephone, internet, or in anyone of their own Apple retail stores that are commonly found in shopping malls. The most popular products are also found in department stores, electronic stores, and even certain Apple vending machines. Due to all of the supplier locations, Apple has made it easy and convenient for their customers to access their products, services, and assistance. Stakeholders of the company include the employees, stockholders, and customers. If there is any major change or re-organization of the company the employees will be impacted and this may potential affect the stock prices which will affect the stockholders whom are essentially the owners of the company. The Apple stock at the time this paper is being written is at $502.36 a share which is very high and this truly shows that value that shareholders have for this company. The customers are stakeholders in the company because all of the managerial decisions will trickle down to the product and price. As of January 2013, there were executive changes at Apple that created drama for people in the tech press field. â€Å"The man responsible for much of Apple’s hardware design since 1996, Jonathan Ive is now in charge of design of both software and hardware† stated Dan Moren, 2013. The late Steve Jobs was Apple’s chief executive officer that had a major influence on the startup of the company and the success of the company. This became the molding for the company’s culture today which has been influencing our pop culture for more than a decade. The company continues their innovation and delivers their premium products and assistance to their customers regardless of the organizational changes that have been taking place within the company.

Monroe Doctrine Essay Example | Topics and Well Written Essays - 2500 words

Monroe Doctrine - Essay Example The Monroe Doctrine was expressed by President James Monroe in 1823 within his annual address to the Congress. The main idea of Monroe’s message was the following: until European powers doest not interfere with the U.S. interests in Western Hemisphere, the United States would not interfere with European spheres of interest in Eastern Hemisphere. In a nut shell the Doctrine stated that, â€Å"The United States would not interfere in European wars or internal affairs, and expected Europe to stay out of American affairs.† Authors of the Doctrine emphasized that the document must be viewed as anti-colonialist proclamation intended to prevent further colonization of South and Latin American countries by European states, such as Spain, France and Russian Empire. In its turn, the U.S. planned to maintain neutral position in any clash taking place in Europe or European colonies in Eastern Hemisphere. Consequently, any military conflict taking place between a European country an d its former colony in Americas would be viewed as action hostile toward the U.S.: â€Å"But with the Governments who have declared their independence and maintain it, and whose independence we have †¦ acknowledged, we could not view any interposition for the purpose of oppressing them, or controlling †¦ by any European power in any other light than as the manifestation of an unfriendly disposition toward the United States†." (Monroe Doctrine, 1823). Apparently, the Doctrine was an adequate response to the political situation in Western Hemisphere. In 1815 the Spanish Empire in the New World collapsed. During only 7 years, from 1815 to 1822, Chile, Peru, Colombia and Argentina fought their independence. These newly emerged states sought for the U.S. recognition of their independence, and public opinion in the U.S. was mainly positive on this issue (Dent, 1999). At the same time the U.S. had negotiations with Spain trying to purchase Florida. The negotiations were successful, and once Florida was purchased the Monroe administration recognized Chile, Argentina, Peru, Mexico and Colombia. Apparently, this step may be considered as the first sign of new U.S. policy in Western Hemisphere. Europe immediately reacted to the U.S. behaviour. France and Spain joined together in an effort to restore their lost influence on American colonies. This effort was opposed by the UK government which was not willing to allow France regain its former influence in America: "All the work of Wolfe, Chatham and other eighteenth-century British statesmen to get France out of the New World would be undone, and France would again be a power in the Americas"(Monroe Doctrine, 2005). Yet, support of the Holy Alliance (Prussia, Austria and Russia) was strong enough for the U.S. and UK to seriously consider the threat. Seeking support in its attempts to keep France out of Americas - the result of nearly century of UK efforts - British government proposed to the U.S to ally and warn off both Spain and France from new interventions in the New World. However, the attitude of U.S. government toward the UK proposal was ambiguous with T. Jefferson and J. Madison, Monroe's renowned predecessors, supporting it and John Q. Adams, Secretary of the State, opposing it mostly due to concern that Mexico intended to extend its influence to Oregon and also due to recent diplomatic conflict with the Russian Empire (over the northwest coast of North America). During the meeting of Cabinet that took place on November 7, 1823, Adams convinced the other statesmen to

Extended Schools in UK Essay Example | Topics and Well Written Essays - 4000 words

Extended Schools in UK - Essay Example It has thus a host of multifarious activities to perform as a 'cornerstone' of the emerging 'knowledge economy' and the 'hub' of the community life. In this essay we explore the theory and practice of, and the issues around, extended schooling. The discussion would be more meaningful against the background of the history of the concept of 'extended school' and its implementation. We, therefore, turn first to a short 'review of the literature' on extended school in the following section. The scheme of extended schooling first appeared as a 'full-service schooling' initiative in the United States and has been functioning there as part of the school system for a number of years. Some of these services have included the provision of welfare amenities of health and cleanliness, support services in the form of school counsellors, and various sports and youth activities. However, the recent interest in 'full-service' schooling has its origins in the remedial or ameliorative concerns, which appear to have been basically transplanted into the extended schools in England. The focus has been on the provision of health and social care services. The new community schools in Scotland (1999) was said to have been the first major implementation of the 'extended school' scheme in the UK. In Wales, the idea of community-focused schools has been used to investigate the need and feasibility of a similar provision. However, the idea of providing different services on school premises is hardly new (Walker et al., 2000; Tett, 2000; Raham, 1998, 2000; Smith, 2001). Since the nineteenth century there have been various examples of schools offering medical and welfare services alongside their traditional activities of teaching. Dryfoos has argued that the original model was that of the school-based health and social services centre where services were brought in by outside agencies in concurrence with school personnel ( Dryfoos,1994, p.142). They were to be 'one stop, collaborative institutions' (ibid, p.13). As to what elements should now be present in the concept, Dryfoos seems to be of the view that such a service package should include both 'quality education' and 'support services' (1994. p.13). The underlying principle behind the concept of the full-service or extended school is based on the recognition that schooling, for many, would become meaningful only when 'a range of welfare and health services were in place' along with quality teaching (Smith, 2001a). Soc ial disadvantage must be addressed in order to effectively tackle educational underachievement (Olasov and Petrillo, 1994; Carlson et al., 1995; Raham, 1998; Smith, 2001). Dryfoos (1993) has noted that the impetus for the development of the full-service school approach emanated from the recognition that the schools were often unable to cope adequately with individual student needs in areas such as the social, health, emotional and cultural requirements of their pupils. Hence, much of the literature is based on the premise that 'schools cannot do it alone' in the light of the multiple challenges they, and their students, families and communities face (Dryfoos, 1994,). Schools in UK have to cope with problems

Locating Topics of Interests Research Paper Example | Topics and Well Written Essays - 1000 words

Locating Topics of Interests - Research Paper Example This paper will seek to develop eight topics based on virtual project management where it will locate peer-reviewed journals and annotate at least four of them. 2. The Journal of the American Medical Association A review of authors revealed that, conflicts of interests in matters concerning safety of vaccine research seem to have a place for authors withholding CO1s declaration. This journal modified part of its policies to make sure less transparency of CO1s investigations. This appeared so since the ties between the author and the manufacturers of the vaccine are pervasive. A review carried out by authors of vaccine safety articles shone light on this issue and published it on top journals making the claims as well as the ties invasive. In conclusion, this topic puts across that the safety of people should come before instilling experimentations in order to avoid side effects. 3. The scientific journal fall In this topic, the writer gave priority all editorial findings regarding di sputes between a vaccine produced by a particular vaccines manufacturer and the author who published the article. In this sense, professionals such as psychologists took this opportunity to clear any negative issues that could affect their profession. In conclusion, the topic describes the ties between the vaccine manufacturer and the author of the article as pervasive. 4. Virtual project management: The rise of internet The development of the internet and the rise of collaborative software as described in this except instilled a fresh dimension into management of projects. The recent literatures explored in this topic depict evaluation of virtual project management as well as virtual teams have received great influence from different technologies. Furthermore, the extent of development of technologies affect members in dispersed cites with their projects (Dunford, Doyle, & Doyle, 2011). This topic concludes by deducing that, besides the objective that communication channels have br ought about opportunities for members participation, it is still agreeable that it is hard to manage virtual teams than an on-site team. 5. Identification of virtual teams Definitions available in this literature explain that, a virtual project management involves systems whereby virtual teams join forces for a finite length of time with a specific goal. As this topic concludes, it explains that there is truth in the statement made by many that, with technology everything becomes new even it is old. Recently, technology led to enhanced possibility of enabling geographically dispersed employees to work on a similar project. Corporate structure within virtual enterprises and virtual companies weave the same related thread of thoughts into their telecommunication departments (Taylor, 2011). 6. Virtual teams in an organizational system Those promoting the concept of virtual teams assert that these teams are very advantageous. Upon conclusion, this topic makes it clear that, even though there no disputes, most of the literature expounding on such a topic focuses on team networking, and project teams either implicitly or explicitly. 7. Interests of virtual team management As opposed to just mere curiosity, virtual teams have drivers of leading interests in which they attract the best workers

What is the secret meaning of the art and how we knowers could access Essay

What is the secret meaning of the art and how we knowers could access the secret through emotions and imagination - Essay Example Through cultivating and releasing the spirit of creativity, art becomes a perfect tool for healing patients with serious mental disorders. Art liberates the process of creativity in our minds and seeks solutions to the problems affecting us in our lives. It helps us provide freedom and sustenance to our creativity and hence moving freely to any direction that is most appropriate for us. Art has acquired great significance in treating patients with critical mental sickness, patients with severe depressions, patients with anxiety and emotional disorders. In addition, some programs organized for solving addiction problems incorporate art to make them perfect. To add on that, people without mental disorders also use art to communicate their ideas, feelings, facts, thoughts and findings (Rustin 5). A person with serious fright attacks and horrified by most of the things that many take in a pace that include conversation with cashiers, driving and receiving telephone calls may remain stagnant in his house just because of fears outside. Art therefore, focus on current issues that induce stress as well as those of the past. Through art, the individual can learn how to deal with the problems knowing that he cannot run away from them. Paintings can also help remember previous problems and the means used to address them and cultivates a culture of acceptance in oneself and confidence in dealing with the problems. The paintings create a visual impression in one mind, which tends to reduce the imagination as one learns to familiarize himself with the situation. Art in this way makes what is invisible visible and thus easier to fight an enemy you see than one you do not see (Rustin 7). The arts paintings depicting the various problems facing the society will help reduce the imaginations and suffering. Problem sharing between individuals helps to reduce the adverse effects created by the problem. A painting therefore helps to create an impression of problem
