Earths Elliptical Path Around the Sun

Earth's Elliptical Path Around the Sun Earths motion around the Sun was a mystery for many centuries as very early sky watchers attempted to understand what was actually moving: the Sun across the sky or Earth around the Sun. The Sun-centered solar system idea was deduced thousands of years ago by the Greek philosopher Aristarchus of Samos. It wasnt proved until Polish astronomer Nicolaus Copernicus proposed his Sun-centered theories in the 1500s, and showed how planets could orbit the Sun. Earth orbits the Sun  in a slightly flattened circle called an ellipse. In geometry, the ellipse is a curve that loops around two points called foci. The distance from the center to the longest ends of the ellipse is called the semi-major axis, while the distance to the flattened sides of the ellipse is called the semi-minor axis. The Sun is at one focus of each planets ellipse, which means that the distance between the Sun and each planet varies throughout the year.   Earths Orbital Characteristics When Earth is closest to the Sun in its orbit, it is at perihelion. That distance is 147,166,462 kilometers, and Earth gets there each January 3. Then, on July 4 of each  year, Earth is as far from the Sun as it ever gets, at a distance of 152,171,522 kilometers. That point is called aphelion. Every world (including comets and asteroids) in the solar system that primarily orbits the Sun has a perihelion point and an aphelion. Notice that for Earth, the closest point is during northern hemisphere winter, while the most distant point is northern hemisphere summer. Although theres a small increase in solar heating that our planet gets during its orbit, it doesnt necessarily correlate with the perihelion and aphelion. The reasons for the seasons are more due to our planets orbital tilt throughout the year. In short, each part of the planet tilted toward the Sun during the yearly orbit will get heated more during that time. As it tilts away, the heating amount is less. That helps contribute to the change of seasons more than Earths place in its orbit. Useful Aspects of Earths Orbit for Astronomers Earths orbit around the Sun is a benchmark for distance. Astronomers take the average distance between Earth and the Sun (149,597,691 kilometers) and use it as a standard distance called the astronomical unit (or AU for short). They then use this as shorthand for larger distances in the solar system. For example, Mars is 1.524 astronomical units. That means its just over one-and-a-half times the distance between Earth and the Sun. Jupiter is 5.2 AU, while Pluto is a whopping 39.,5 AU.   The Moons Orbit The Moons orbit is also elliptical. It moves around Earth once every 27 days, and due to tidal locking, always shows the same face to us here on Earth. The Moon doesnt actually orbit Earth; they actually orbit a common center of gravity called a barycenter. The complexity of the Earth-Moon orbit, and their orbit around the Sun results in the apparent changing shape of the Moon as seen from Earth. These changes, called phases of the Moon,  go through a cycle every 30 days. Interestingly, the Moon is slowly moving away from Earth. Eventually, it will be so far away that such events as total solar eclipses will no longer occur. The Moon will still occult the Sun, but it wont appear to block the entire Sun as it does now during a total solar eclipse. Other Planets Orbits The other worlds of the solar system that orbit the Sun have different length years due to their distances. Mercury, for example, has an orbit just 88 Earth-days long. Venuss is 225 Earth-days, while Marss is 687 Earth days. Jupiter takes 11.86 Earth years to orbit the Sun, while Saturn, Uranus, Neptune, and Pluto take 28.45, 84, 164.8, and 248 years, respectively. These lengthy orbits reflect one of Johannes Keplers laws of planetary orbits, which says that the period of time it takes to orbit the Sun is proportional to its distance (its semi-major axis). The other laws he devised describe the shape of the orbit and the time each planet takes to traverse each part of its path around the Sun. Edited and expanded by Carolyn Collins Petersen.

Computer games' the development of children learning Research Paper

Computer games' the development of children learning - Research Paper Example The focus is children between the age of six and ten years old. Video games has a lot of advantages on the development of a child between the age of six and ten. In essence, practically all video games are challenging. This means that playing a computer games involves the brain in a lot of exercises. The child has to learn each and every trick of the game in order to win. Therefore, computer games helps the child develop necessary skills that equips him or her to face more challenging situations in future. Playing computer games enable the child to learn how to follow commands or directives (Blumberg and Fisch, 2013). There is no other way to win a computer game other than through following instructions. It is important to elucidate the fact that there are many ways of playing a particular game. According to Blumberg and Fisch (2013), a child can follow different paths or involve different techniques to win. This calls for creativity. Therefore, computer games inspires children to acquire ingenious skills in the course of development. When playing a computer game, the child has to involve practically every part of the body. Most games requires the player to synchronize and harmonize the thinking part of the game and the physical activities that involve moving the hands, legs, and other parts of the body. Therefore, computer games helps a child to learn how to coordinate various parts of the body to achieve positive results. For instance, a child aspiring to become a surgeon in future can learn effective skills through computer games especially coordinating the mind, the eyes, and the hands. Subsequently, a child is able to acquire better planning and time management skills. Blumberg and Fisch (2013) asserts that some games have specific timeframes and in fact have a timer. This means that the player has to mange his or her time well in order to win. These

Shakespeare Research Paper Essay Example | Topics and Well Written Essays - 2000 words

Shakespeare Research Paper - Essay Example This paper examines and explores the foundations of this theory which in fact grants Francis Bacon the authorship of William Shakespeare’s works. The analysis of the said theory primarily focuses on providing a rationale and arguments which support this supposition. The approach which has been adopted in the paper is based on assessing the theory from an evaluative perspective which is based on identifying the proposals of the advocates of this theory and responses of individuals who doubt this claim. In conclusion, the paper answers a critical question that has been perpetuated by those who remain fascinated by the world of English literature: was William Shakespeare solely responsible for penning down the literary works we link with him? At the heart of the Shakespeare authorship debate is a woman named Delia Bacon, as stated by Shapiro, â€Å"Delia Bacon, more than anyone before or after, was responsible for triggering what would come to be known as the Shakespeare authors hip controversy† (18). ... Thus, Bacon’s objective of unmasking the reality of Shakespeare was motivated by the underlying political characteristics of the playwright’s masterpieces which she could only associate with individuals such as Francis Bacon. Shahan and Waugh assert that despite of the reservations of critics who view Delia Bacon’s account with uncertainty and ambiguity because of her eventual descend into psychological illness, the scholar employed â€Å"†¦remarkably modern methods of literary analysis† to arrive at her claim (204). While, this feature of her account certainly lends weight to the Baconian theory, the critical and intriguing question that has emerged is, why Francis Bacon? The answer to which has been provided in scholarly sources that are evaluated in the paper. According to Shapiro, the name of Francis Bacon soon emerged as one of the key contenders who could be revealed as the ‘real’ Shakespeare (19). As a one of the most prominent ind ividuals of Renaissance, Francis Bacon was a man of many talents; well-read, well-traveled and with the ability to engage the reader with his gifted writing talent. In 1594, he was appointed by Queen Elizabeth to serve as her literary counsel, not only that, through the works for which he was indeed credited such as the eminent Essays, the Novum Organum and the Instauratio Magna, Francis Bacon displayed his extraordinary literary capability (Shapiro 19). Even after his death in 1626, Bacon’s admirers in France upheld his philosophical works in the highest regard, by celebrating the scientist’s life and his contribution to the establishment of social reform. Shapiro claims that a significant

Analysis of the Economic Impact of the Major Social Problem of Poverty Assignment

Analysis of the Economic Impact of the Major Social Problem of Poverty - Assignment Example Indeed, the article vividly shows that the government of New York City must aid the residents in their desire to climb out of their current poverty debacle. Subject: Business Topic: Article Analysis Introduction In terms of discussing the model or economic theory that relates to the issue presented in the news article, the economic theory in focus is a supply and demand theory. As prices of goods and services increase, the demand for the products and services decrease. Likewise, as the prices of goods and services increase, the supply of the goods and services increase (Arnold, 2008). In terms of discussing what economic theory states and predicts about the issue presented in the news article, as the prices of goods and services increase, the poverty level people will reduce their demand for the higher priced products. On the other hand, as the prices of goods and services increase, the business entities are eager to supply more services and goods in order to generate more profits (B oyes, 2010). Analysis of the Economic Impact of the Major Social Problem of Poverty The April 12, 2012 issue of the New York Times article is reflection on poverty. The title of the article is New York City’s Poverty Rate Rises, Study Finds (Roberts, 2012). The paper shows strong evidence there has been an increasing number of New York residents joining the ranks of the poor over the last years. The number of New York City residents has literally increased by 100,000 individuals. With the increase, the poverty ratio soared by as much as 1.3 percent. The new poverty rate is 21 percent. The percent indicates that one out of every five New York residents qualifies as poor. The article further states that New York has one of the highest poverty levels in the U.S. Once New York has implemented a more detailed description which defines who can be classified as a poor individual, current New York City’s statistics of the poor has the largest annual rise in poverty ratio. As J an Windebank emphasized, â€Å"Throughout the advanced economies, the widespread consensus is that employment is the best route out of poverty. Not only are the approaches of both the Old Left and New Right grounded in such a belief, but so too is the employment-focused third way approach of New Labor. In this book, however, our intention is to begin to explain why an alternative third way discourse has started to emerge that rejects an employment-centered approach to poverty alleviation† (Windebank, 2003). The current recession, which started in 2008, is blamed as the major culprit for the ballooning of the poor individuals in New York City. The recession brought a lot of the United States companies into the unfavorable quagmire of bankruptcy. With bankruptcy enveloping some of the companies in the United States skies, those that cannot innovate are forced to close shops. With the closing of the shops, many employees are retrenched. With the loss of their jobs, the retrenche d employees could not afford to retain their previous lifestyle. The retrenched employees had to join the long line of New Yorkers waiting for their turn to grab a set of food coupons. With the slowing of the United States economic wheel into a snail’s pace, statistics showed that one out of every four New York residents, under the age of 18 years, joined the poor of New York, the city that never sleeps. New York City’s Center for Economic Opportunity reported the latest poverty report. Likewise, the 2008 U.S. Economic crisis is

A Personal Reflection Of Developmental Life

A Personal Reflection Of Developmental Life Numerous developmental theories exist today that attempt to explain cognitive and physical changes in the body as we grow older. Some are vague and finite, while others go into extreme detail. Some of the leading psychologists relative to these theories are Jean Piaget (Beilin, 1992) with his cognitive developmental theory, Erik Erikson (Gross, 1987), who developed his psychosocial developmental theory, and Lawrence Kohlberg (Guthrie, 1984), with his moral development theory. It has taken many years for these scholars, as well as intelligent students to polish and critique these developmental theories. Kohlbergs moral developmental theory best accounts for my moral, ethical, and personal development as well as potentially playing a large role in my future development as a senior adult. I respect them all because they all are true in their own way. I just happen to have one theory which applies to me more than the others. As a child, I can remember being cognizant about the direct repercussions of my actions on myself as well as other children. Out of all the conspicuous developmental theories that are commonplace today, I believe that, as Kohlberg stated, it is like saying, The last time I did that I got spanked so I will not do it again (Kohlberg, 1974). Thats exactly the mentality I developed after wrongdoing. In other words, a behavior which is thought to be ethically incorrect usually results in the culprit being punished, driving childrens moral choices. The reflection in terms of how and why Kohlbergs portions of stage one of his theory relates to my childhood is because even though I was quite obsequious, I was surrounded by people who held what they thought were universal moral/ethical developments; these people had general principles to follow that would be deemed appropriate by the majority of citizens, as well as being able to have the moral fortitude to give instead of taking. I admit that I was quite selfish at this early age. Kohlberg devised that his theory was composed primarily of three major levels of development. These primary levels are known as pre-conventional, conventional, and post-conventional. In all, there are six sub-stages that are underneath his primary levels in regards to his moral developmental theory. I can attest that I judged moral acts based on their repercussions. When I was young, I would not steal food from drug stores because I knew if I got caught, they were not going to treat me well in jail. The main point with respect to Kohlberg and my childhood is that I did not grasp what it was to have broadly acquiesced moral values. This is what Kohlberg argued in his first stage of the preconventional level of development. Furthermore in stage two of the preconventional level, which is defined by the self-driven person, proclaims whats in it for me, where correct behavior is based on whatever is in the individuals best interest (Kohlberg, 1974). A young child in the preconventional moral stage has not yet acquired or internally digested the conventions of society with respect to what is right or wrong. Instead, they concentrate on their convergence on the transcendent repercussions that specific states of affairs may bring to them (Kohlberg, 1971). This stage of development concurs with my lifestyle as a youngster. I was selfish and I thought I was completely free from any wrongdoing because I was a child. I failed to develop any rational moral belief system at this point in my life. The conventional level of moral reasoning is typical of some adolescents and a great deal of adults. In the general consensus, people who justify their actions in a conventional way arbitrate the morality of behaviors by discerning them against societys general views and ethically-guided behaviors. Persons in this stage of development either approve or decline from other individuals as it pertains to societys accordance with the conceived role. As Kohlberg put it, they try to be a good boy or a good girl so that they can meet the expectations of society having apprehended the knowledge that there is intricate value in so doing (Kohlberg, 1973). During this broad conventional stage of Kohlbergs theory, one must note that conventional morality is dependent by an acceptance of societys assemblage related to what are right and or wrong. In the fourth stagein the same level as the thirdit is the drive for authority, social order, and obedience that defines its presuppositions. In the fourth stage, it is absolutely essential to adhere to laws, dictums, and social conveyances due to the fact that they are vital in creating a stable and functional society. I can 100% relate to Kohlbergs fourth stage when I was an adult. For example, I ended up picking up rank in the military and was in charge of hundreds of Marines that I was responsible for in every way. It was essential to obey what you were told to accomplish by your supervisor. If you did not finish by the time he or she returned, you can go to jail, lose your money, lose your rank, and even lose your house. The Marines take disobedience to its laws very seriously. Thus, Kohlbergs theory is at work here during this phase of my life because I was dedicated to adhering to the rules that governed me, because it was my duty to protect the U.S. foreign and domestically. With respect to stage five of Kohlbergs theory, my life as I got older and travelled more often became committed to the social contract driven force. That is, I held the worldview and made myself respect that every culture-also known as cultural relativism-has its different views on what is acceptable in society and what is not. I had to learn to respect that because I was used to my own rules and regulations. But when my units in the military deployed overseas, we were under the jurisdiction of foreign governments. Such perspectives should be mutually respected as unique to each person or community. For example, in the United States, prostitution is not something very good to proclaim as a job, and is illegal in every state except for one. This is in direct contrast to other countries, where sex is actually a business industry and is widely promoted. People do it so they can make money and live. It was hard to accept at first, but once my selfishness went away and my mind widened, my morals changed to universal ones, as I will discuss lastly in stage six in Kohlbergs post-conventional stage. After I served in the military, learned to obey and respect other cultures, along with my travelling experiences, I started to finally develop my own universal morals. This I believe started me in stage six of Kohlbergs theory. For example, I believe that murder, adultery in any case, preemptive violence and war, and saying the Lords name in vain are all immoral and should be shunned. This is a mirrored reflection of Kohlbergs, in particular stage six, of his moral development theory. It pos tulates that moral reasoning is based on abstract reasoning using universal ethical principles. Kohlberg and his peers developed the just community schools approach towards promoting moral development (Power, Higgins, Kohlberg, 1989). I thought that anyone in society would think it would be morally right because stealing does not always have negative connotations. This goes along with Kohlbergs conventional stage of development. I tended to weigh the morality of things based on society. For example, I used to believe war was the right thing to do as a preemptive measure. But when I became an adult, my beliefs changed drastically and were more coagulated. I started becoming more diplomatic and resolving issues by negotiations, not by combat or any other physical altercations. In Kohlbergs sixth stage, I believe that was the turning point to how I judge people and other things and situations. Now I will address how Kohlbergs moral theory applies to my current lifestyle as well as to contemporary world affairs. Reaching such a high stage was not noticeable to me for a long time, and it took a lot of hard work to reach it, but then I started giving large thoughts empathetic to lots of individuals. For example, I saw massive amounts of impoverished people in the Dominican Republic and Puerto Rico. There should be no poor individuals in the world; there should be a more rigid attempt to completely eradicate HIV. But the results still have not satisfied me. Efforts to tame the HIV epidemic have only been haphazard (Kaiser, 2010). The key methods are using condoms or teaching individuals how to maintain abstinence. Recently the U.S. cut the condom program before President Bush left office, which was a death sentence to millions of Africans who were participating in the program. The former First Lady Laura Bush made an underrated attempt, which promoted the use of condoms and ha nded them out in African regions, which people thought was evolutionary. However, she did not advocate for abstinence as much as she could have (Kaiser, 2010). Overall, I feel that such differential perspectives among cultures should be respected as unique to each person, group, tribe, culture, or community. I learned this after travelling overseas, interacting with differential people from diverse cultures, and seeing what really goes on in the world. I thought that every country loved America and that we were viewed as the benevolent country that came to the worlds aid when it needed us. I thought that most, if not all countries, wanted freedom, liberty, and justice as a lot of people incorrectly thinks. When I was in Russia, many citizens were angered by our presence as Americans and hated the idea of complete freedom and looked at us Americans like we were the bad people. One Russian, out-of-the-blue, came up to me and said, Iraqà ¢Ã¢â€š ¬Ã‚ ¦BIG MISTAKE. I did not understand the anti-American sentiment. This is in no way a political statement nor does it reflect my beliefs, I just want the reader to be aware of how other cultures view the U.S. and its effect on moral systems. This point aforementioned regarding the Russians is directly consistent with what Kohlberg was saying regarding how society has different views. It is called cultural relativism. Speaking in terms of the future, I would like to work for the FBI and catch criminals, whether they are bank robbers, fraudulent vices, computer hackers, or any criminal of any kind. Because of my developed and polished moral and ethical views, thanks to Kohlberg, I also plan to increase my voluntary practices with community organizations like Habitat for Humanity, the Peace Corps and AmeriCorps. One of my academic goals is to graduate with honors and reach graduate studies. I am determined to succeed and at that I especially mean academically. I also want to get in better shape so Ill feel better. After delving into Kohlbergs moral development theory and also my experience through an adult, I believe that his theory best explains my moral/ethical development, adherence to laws and engage in obedience, and countless other tidbits. Kohlbergs moral developmental theory best accounts for my moral, ethical, and personal developments as well as potentially playing a large role in my future development as a senior adult. It also explains the rationale for punishment administered to me in the past, being of self-interest, and conjuring my own universal ethical principles. Although a lot of the developmental theories are well supported and studied, I believe that relative to my own life that none of them have the clout and or efficacy in its developmental explication that Kohlbergs theory has. Ultimately, I found Kohlbergs theory to be the best one that explains historical, contemporary, and very likely my future endeavors as well as I still mature as an adult. After rigorous delving into Kohlbergs material, I am confident that his moral theory is extremely accurate and could be used as a guide to help in developing individuals.

The Experience Of The War In Korea Essay examples -- Personal Narrativ

The Experience Of The War In Korea The Korean War was a trying time for America. The nation was getting involved in a war that had little or no possibility of a fortunate outcome. The Korean people were divided among how the country should be run. A uniform system of government looked like it may never come to be. In order to protect one of its vital interests as well as to prove to the rest of the world that America didn’t stand for communism, the United States began taking up arms. The war would prove a most difficult task to achieve successfully. In fact, it was almost impossible to continue fighting what seemed to be far from a worthy sacrifice of American lives. It was January 10, 1950 when Robert Marrara of Arthurdale, WV, among thousands of other men, were drafted and sent to California for basic training. Robert is 5’9" tall with wavy, silver hair and a structure that shows just how strong of a man he is for being 72 years old. Of Italian descent his parents immigrated here and he was one of several children. They lived in poverty, as most of America did, through the thick of the Great Depression. He attended electrical school after college didn’t seem right for him. He is a genius by all standards but is far too modest to admit it. His experiences are enough to fill days full of stories and the personal interview he gave was a treat. Robert recalls how difficult coping with the situation in Korea was, but also how he welcomed the challenge: "It was tough and, you know, but I really, I have to say that I did enjoy being, because my knowledge was – my previous training before I got in the army – was the very thing I needed to do the job I was assigned to do. And because I could do it in such a good way – and you ... ... a  ¾ inch electric drill and I took a crank with me and I made a shaft for that drill so that it could drive that engine and start those engines with that electric drill and that 20 minutes or 25 minutes after I got back over to the quartermaster, I had all them engines running with that electric drill. From that time on, during the whole summer and fall when they had ice and ice cream I got it delivered to my tent. They delivered me ice two times a week and they’d deliver ice cream one time a week. A three-gallon can for my carburetor-ignition repair section." Throughout the interview Robert emphasized the value of his work during the war just as he values the war effort itself. Overall, those who died did so for a worthy cause (Marrara, Personal Interview). America backed its promises to defend South Korea, even though the effort could be viewed as ill decided.
