Physics of football Essay Every Sunday afternoon in the fall, all across America, televisions, radios, and Internet broadcasts are tuned to the big football games. The sport of football has grown in popularity since the day it was invented, but not all of the views are good. The sport of football is viewed by many as a cruel and primitive sport, however every aspect within the sport of football is based in the field of physics. To begin to understand the complexity that is the game of football one can start by looking at how the punter needs to know the laws of physics to kick far. A punter’s job is to execute a drop kick (holding the football out and dropping it, then kicking the ball in midair) so as to give the other team the worst field position possible. This goal is only achievable with a kick that propels the football very far both horizontally and vertically. The punter is in charge of three things at the time of the kick: the velocity, the angle of the kick, and the rotation on the ball. Velocity is the speed at which the ball is propelled from the punter’s foot. The angle at which the ball is kicked combined with the velocity determines the distance the ball will travel. A ball kicked at a steeper angle with high velocity will have more hang-time (amount of time the ball is in the air), but will not travel very far. However, a ball kicked at a shallow angle with a high velocity will travel far, but it will not have the hang-time that many players desire (a punt with a long hang-time allows the players to get to the punt returner easier). Lastly, the rotation a punter puts on a football greatly affects how far the punt will go. If the ball is punted end over end, it will have more air resistance, slowing it down resulting in a shorter punt. A spiraling punt breaks through the air decreasing air resistance allowing for a kick with more distance. These same aspects are the ones applied to a quarterback when throwing the football (except without the kicking). One of the more sought after positions, and my personal favorite to play, is the running back. The job of the running back is to receive the football from the quarterback, and then try to gain as many yards as possible before being brought down to the ground by a defensive player. The running back lines up usually about three to five yards behind the line of scrimmage. This space allows the running back to accelerate to his top speed before he meets the defense. For a back to be able to change direction as he is running, he must plant his foot into the ground and apply force in the opposite direction. To stop going in one direction, a running back uses two different forces, the first of which is the force of friction (how hard it is to slide one object over another), and the second is the force with which the back applies. When a running meets a defensive player, his momentum must be greater than the momentum of the defensive player’s in order to break the tackle. On the opposite side of the ball, the linebacker is the defensive equivalent to the running back. He also is stationed three to five yards from the line of scrimmage in order to have room to accelerate. For a tackle to be made, the momentum of a defensive player must be greater than or equal to that of the offensive ball carrier. Momentum is found by multiplying the weight of an athlete by the speed at which he is moving. If the momentums of the two athletes are the same, then both players will come to a stop and in the game of football if the ball stops moving forward, then the carrier has lost. In my own experience, coaches have always told me to tackle low. The reasoning behind this is that a man’s center of gravity is usually located at just above the naval, and hitting below this point causes the runner to rotate, taking his legs off of the ground. If a player is hit above this point the tackler will just roll off, and if a player is hit on this point, he will be forced in to the direction he his hit, but it may not bring him down. The sport of football is a highly scientific game, and not the savage sport that many people see it as. Every aspect of the game can be figured through various physical formulas.

foolear The Wise Fool in Shakespeares King Lear Essay -- King Lear e

The Wise Fool in King Lear      Ã‚  Ã‚   Whether or not the role of the Fool is an important one within King Lear is arguable. Although he seems to have great insight into much of the plays main events, he seems not to have any real influence on both the plot as well as the outcome of the play. He remains the sole character who does not have any direct link with the events of the plot, coupled with an unusually early exit; this raises the question of his significance. However at the very least he does certainly serve as entertainment not only for Lear but the audience as well, with his honesty, wittiness, and clever speeches that not only adds to the light humour but also to show us that the Fool could indeed be perceived as being one of the wisest characters in the play.    The main roles of the Fool seem to be as Lear's conscience, as a comedian to provide light relief from the tragic play as well as a means of communicating his themes such as the idea of foolishness, self-knowledge. In addition, he is the only person with the ability to speak to Lear in the manner he does. He also serves as a reminder for Lear for his actions within the play, in particular his stupidity and mistakes.    The Fool appears in the middle of Act I Scene 4 of the play and immediately we can clearly see his integrity when talking to others. He tells Lear "thou must needs wear my coxcomb" which suggests the king to be the Fool rather then himself and that Lear was foolish to divide his kingdom as he has done. Kent before him had criticized Lear for his decision causing him to be banished from the kingdom, however the Fool receives no such punishment showing us that he can get away with actions that are far more courage... ...easons as to why he actually leaves remaining unseen again in the play. At this point in the play, Lear finally goes mad; therefore, this suggests that the Fool unneeded, as Lear no longer has the ability of reasoning. This also suggests that the Fool is indeed a metaphor for Lear's conscience. Additionally, this is also the point where Lear begins to finally learn that he has made some terrible mistakes. This could be suggesting that the more foolish we become, the wiser we are because as Lear finally loses his mind, he finally gains insight into his mistakes.    Works Consulted:    Shakespeare, William.

Because I Could Not Stop for Death Emily Dickenson

Miranda Jennifer Professor A. Tripp English 355 1, October 2012 Loss Is Nothing Else but Change Experiencing a loss raises overwhelming feelings that are difficult to cope with. The emotions that accompany any kind of loss can be intense and varied. There are stages of grief that everyone goes through. A sense of shock or denial usually come first followed by anger. Bargaining follows anger, then depression, and finally acceptance. In â€Å"Because I Could Not Stop for Death,† by Emily Dickinson, the speaker is taken on an un expected journey that illuminates her path of mourning, which helps her come to an acceptance with her loss.The title: â€Å"Because I Could Not Stop for Death,† states that the speaker could not begin to grieve the loss. The speaker knew it had to end but could not bear to end it on his of her own, thus â€Å"Because I could not stop for Death,/ He kindly stopped for me;†(Lines 1-2). Dickinson mentions the speaker’s outfit as a symbo lism of unpreparedness. â€Å"For only gossamer my gown/ my tippet only tulle,† (15-16). Dickinson’s word choice play a vital role throughout the poem. The term â€Å"immortality†(4) signifies that the journey would never end. The speaker is well aware that the journey embarked on was not a round trip.The speaker is taken on a journey filled with many experiences, all which he or she accepts and learns from. This journey illuminated the speaker’s perspective of grieving with the loss of something or someone. According to Oxford Dictionaries, the adjective illuminating can be defined as: â€Å"to help to clarify or explain† (Illuminate). Even though the journey was unexpected, it brought enlightenment to the speaker’s perspective of his or her loss. People feel pain when going through a loss, but in â€Å"Because I Could Not Stop for Death,† the speaker accepts it with ease, â€Å"I had put away/ My labor, and my leisure too,/ For his civility†(6-8).The speaker is essentially relieved concerning the loss. He or she is finally able to forget about everything that worries him or her. Overall, the loss brought the speaker tranquility. In stanza three, the speaker takes a trip down memory lane. â€Å"We passed the school, where children strove At recess, in the ring; We passed the fields of gazing grain, We passed the setting sun. † Remembering past times is a typical thing to do when dealing with grief. The speaker of â€Å"Because I Could Not Stop for Death,† accepted his or her loss, for it eventually led her to an immortally full of bliss.When losing someone or something, it is important to know that it will get better. Losing someone or something can be the most devastating thing for anyone, but it is important to understand that once you come to acceptance with the loss, there is light behind the tunnel. The speaker of the poem is well aware of this and he or she agrees to the journey, not knowing where his or her destination would be. After a long journey of mourning, the speaker is taken to a new home, where he or she can finally be at ease. â€Å"We paused before a house [†¦]/ The roof was scarcely visible,†(7,9).A new home signifies a new beginning. Over all the loss that the speaker is going through, has brought him or her to a new commencement in his or her life. â€Å"’Tis centuries, and yet each Feels shorter than the day I first surmised the horses’ heads Were toward eternity. † The best thing one can do when moving on from a loss is to take each passing moment as an opportunity to grow. The speaker was able to view his or her loss as an opportunity for emotional growth. Thus, the journey that the speaker in â€Å"Because I Could Not Stop for Death† took illuminated his or her path towards the acceptance of his or her loss.Marcus Aurelius said, â€Å"Loss is nothing else but change, and change is Nature’s deligh t. † Works Cited Dickinson, Emily. â€Å"Because I Could Not Stop for Death. † The Compact Bedford Introduction to Literature: Reading, Thinking, Writing. 9th ed.

Nature of personality paper

Human personality is a complex construct that includes a number of influences, which are, however, often opposed in classical psychology: genetic versus environmental factors; free will vs. determinism and conscious versus unconscious behavior. The present paper is intended to analyze this spectrum through the prism of various psychological theories. Freudian, or psychoanalytic approach, alleges that human behavior depends upon the instincts, manifested in Homo sapiens in more ‘socialized’ form. Freud (Carver and Scheier, 1995) divides personality into three parts: the Id, or the subconscious, or the reflection of human instincts and most egoistic and childish desires, the Alter Ego, or human consciousness (the self), which provides mental determination of behavior, and Super Ego, or conscience, which acts as an internal censor and places restrictions on both the Id and the Alter Ego. The scholar suggests that human behavior is mostly determined by the Id, as it comprises the greatest part of personality, but the Alter Ego and the Super Ego develop throughout developmental course under the influence of social environment. Thus, psychoanalytic approach prioritizes environmental factors over genetic, unconscious behavior over conscious and determinism over free will (Cook, 1984). Neo-Freudians maintain most psychoanalytic concepts, but develop a unique framework of human Ego as not merely a mediator between the Id and the Super Ego, but   rather as a separate force, less dependent upon the other two constituents and therefore more autonomous in personality formation. For instance, Erik Erikson held that â€Å"the Ego’s main job was to establish and maintain a sense of identity. A person with a strong sense of identity is one who knows where he is in life, has accepted this position and has workable goals for change and growth. He has a sense of uniqueness while also having a sense of belonging and wholeness† (Cook, 1984, p. 258). Also Neo-Freudian or psychodynamic approach is viewed as a single doctrine, its proponents vary greatly in their views on the spectrum of human personality: for instance, earlier Neo-Freudians like Carl Jung stated the power of unconscious behavior over conscious and of determinism over free will, whereas the next generation of psychologists, who identified their views as ‘Neo-Freudian’ (like Erikson and Horney) alleged that human behavior is mostly conscious and not necessarily determined by physiological or instinctual drives. All Neo-Freudians, however, consent to the notion that environmental influences are stronger than genetic (Cook, 1984; Funder, 1996). Biological perspective focuses on the dominance of genetic and physiological factors and stresses the influence of certain mode of neural activity on human personality (temperament). This approach highlights genetic factors as opposed to environmental, biological and genetic determinism as opposed to free will and unconscious behavior (for instance, the work of muscles, peculiarities of digestive process as they relate to human diurnal activity in both physical and social contexts) as opposed to conscious. Trait theorists view human personality as a set of traits, which might be interdependent or independent, in addition, certain traits might predominate over others (central traits and cardinal trait, in Allport’s interpretation) (Cook, 1984). Trait theorists provide only a brief framework of personality development, as most of them argue that individuals tend to focus on current settings (functional autonomy of motives) and therefore each developmental course is unique. Thus, the scholars view free will and social environment as behavior-shapers and insist that human actions are rather conscious than unconscious (Funder, 1996). Humanistic approach, which derived from Roger’s view on personality, which focuses on â€Å"healthy development in terms of how the individual perceived their own being† (Funder, 1996, p. 370). In addition, â€Å"a healthy individual will tend to see congruence between their sense of who they are (self) and who they feel they should be (ideal self)† (ibid). Human development is therefore a path to the ideal self, and the person by themselves decides on the mode of their progress, so this approach rejects determinism and genetic influences. Due to the fact that the personality is formed as a result of self-perception and self-analysis, this approach priorities conscious behavior (Cook, 1994). Behaviorists study human personality and development as a progress of behavior and social competence, as they (as phenomenologists) generally suggest that the matrix of human actions is the only true reality (rather than mood or personality traits). The central points of behaviorism are the notions of classical conditioning (stimulus-behavioral reaction), operant conditioning (action-reinforcement-response) and social learning (behavior depends on human expectancies concerning the possible reward). Thus, most behaviorists believe in determinism, the dominance of environmental factors over social (Carver and Scheier, 1995) . Certain behaviors (e.g. reflex-based), are, in their opinion, unconscious, whereas other behavioral manifestations are the result of human expectations and perceived roles (Founder, 1996). Cognitive paradigm ‘is focused on the individual’s thoughts as the determinate of his or her emotions and behaviors and therefore personality† (Founder, 1996, p. 307). Cognitive theorists view human development as gradual evolution of human ability to process and analyze the informed received through perception after the accumulation of experience. For instance, Kelly’s Fundamental Postulate can be formulated in the following way: †a person’s process are psychologically channelized by the way in which he anticipates events† (ibid, p. 308). Hence, this approach doesn’t accept determinism, views human behavior as conscious in practically all aspects and manifestations. Neither genetic nor environmental influences are positioned as prominent personality-shapers, as human perception and thinking (internal psychological factors) are more important. Nevertheless, environment is more likely to have power over personality formation, they believe. As for me, I don’t think that the spectrum of these dichotomies should be necessarily studied as three pairs of opposing factors. Due to the fact that scientific progress has allowed partially de-scripting the DNA, it has appeared that genetic factors determine human neural activity and might shape such traits as emotiveness or assertiveness. Furthermore, conscious behavior should not be contrasted to unconscious, as the line that divides both behaviors is not actually clear; human acts might be influenced by the combination of conscious decisions as well as unconscious and barely controllable drives. In addition, certain degree of determinism is always present in human behavior and personal development (as we all are mortal creatures, so we plan our future keeping in mind this fact), whereas free will allows concentrating on current issues. Thus, all these factors should be viewed as a complex, or holistically. Reference list Carver, C. and Scheier, S. (1995). Perspectives on Personality, 3rd edition. Massachussets, Allyn and Bacon.

SAT Admission Requirements The Importance of the SAT

SAT Admission Requirements The Importance of the SAT SAT / ACT Prep Online Guides and Tips If you’re currently applying to college or getting ready to apply to college, you’ve probably heard of the SAT and/or the ACT.You may already know thatthe SAT is a standardized test which high school students take before applying to college, but how important is the SAT in college applications? It’s hard to overstate the importance of the SAT. Your testscore will beone of themost important partsof your college application (if not themost important part). In this guide, I'll explain why test scores are a key part of your application and how you can determine the SAT admission requirements for the schools you're interested in. Why Is the SAT Important to Colleges? There are two main reasons for the importance of the SAT to colleges. Let's go through them one at a time. #1: Your SAT Score Is How Colleges Compare You to Other Applicants from Around the Globe. Applicants to one university will come from different backgrounds, will have attended different high schools, will have taken different classes, will have done different extracurricular activities, but all applicants will have taken the SAT and/or ACT (at least at non-test optional schools). Your SAT score reveals whether your GPA and transcript are accurate representations of your academic ability. Admissions officers use your SAT/ACT score to figure out if your grades were inflated or not. If you have a 4.0 GPA with a perfect 1600 SAT score, admissions officers will likely be impressed and think your GPA is reflective of your academic potential.If you have a 4.0 GPA with 1000 SAT score, admissions officers may think your grades were inflated and that your SAT score is a better representation of your academic potential. A high SAT score can also make up for a lower GPA.If you have a 3.0 GPA with a perfect 1600 score, a college admissions officer may be willing to overlook your GPA and consider your SAT score as an indication that you’re college ready. #2: Colleges Are Judged by Their SAT Score Ranges The SAT is important to colleges becausethey use it tojudge your academic preparedness for college. However, it's also important to colleges because if you're admitted, your SAT score will be incorporated into their yearly SAT statistics. Each year, universities publish their freshman admissions profile (see an example of Princeton's freshman admissions profile).In this profile, collegesprovide the data on admitted students.The data includes either the 25th/75th percentile SAT/ACT scores (sometimes referred to as the middle 50%) or the average SAT/ACT scores of admitted students. However, usually, the 25th/75th percentile is provided instead of average score.The 25th percentile score means that 25% of admitted students scored at or below that score (and therefore 75% of admitted students scored above).The 75th percentile score means that 75% of admitted students scored at or below that score (and therefore 25% of admitted students scored above).The average score is just what it sounds like, an average of all the admitted students scores. The public judges this data to perceive the selectivity of the school (the higher the range, the more competitive or â€Å"better† the public thinks the school is).When you think of Ivy League schools such as Harvard, UPenn, Columbia, you likely think, "Wow those are good schools!" Why do you think they are good schools? You might think of their alumni or campuses. However, many lower ranked schools such as Denison have beautiful campuses with famous alumni like billionaire Michael Eisner. You might think of their low admissions rates, but there are othercolleges with comparable admissions rates tothe Ivies. The mainreason you associate Harvard, Stanford and other top colleges with prestige is because of their published SAT score ranges and their ranking. When doing research on applying to colleges, you likely came across the US News World Report ranking of US colleges.Every year, US News World Report assembles their rankings based on several categories including the SAT scores of admitted students.If you’re admitted to the school, your SAT score will be factored into that school’s overall national ranking in US News World Report. Top colleges such as Harvard, Yale, and Stanford want your SAT scores to be agood so that it reflects well on them. Even "second tier schools" such as Vanderbilt, USC, and Emory care about thisbecause they hope to continue to rise in theUS News World Reportrankings. Don't be blinded bybeauty or rankings! Find the right school for you! What Does This Mean for You? Because colleges rely so heavily on SAT scores in their college admissions process, you want to make sure that you have an SAT score that fits their expectations. How do you figure out what that theirscore expectation is? Remember, those score percentiles I mentioned earlier?As a brief refresher, colleges publish an admissions profile every year that shows either the 25th/75th percentile SAT/ACT scores (sometimes referred to as the middle 50%) or the average SAT/ACT scores of admitted students. Admissions officers use this data as the standard for the students they admit.Colleges willbe looking for applicantswho are in or above this range (or at or above the average). That way colleges are always getting the same or better caliber student (to either stay the same or increase their rankings). At PrepScholar, we recommend trying to get your score at or above the 75th percentile score for your target school to give yourself the best chance of admission.

LPN -BS TRANSITION Essay Example | Topics and Well Written Essays - 750 words

LPN -BS TRANSITION - Essay Example There are three basic aspects that can be used to distinguish between these two levels of nurses: education, the amount of salary paid and their responsibilities. In terms of education, each level requires different educational approach from the other. Even though both RNs and LPN requires basic BS, the duration for completing the program differs. In United States of America, most institutions take between one and one and half years to train LPN nurse. On the other hand, it takes from two to three years to train RN nurse. Upon completion of the training, the RN nurse graduate with professional nursing degree while LPN nurse graduate with practical nursing degree. Therefore, both training results to an award of BS but it is clear that RN is advance more than LPN. The reason why RN training takes more time as compared to LPN training in universities and colleges is that RN has additional courses such as community health, biology as well as administrative courses (Sherri, Jean, Kathryn, & Katherine, 2012). Consequently, any student with an intention of becoming a RN must devote an additional studying time as opposed to LPNs. However, there are differences between RN and LPNs as far as responsibilities are concerned. Broadly, the RN supervises the operations of the LPNs. It is the responsibility of the LPNs to undertake the basic nursing roles of reporting to both the RN and doctor. In particularly, LPNs perform the following roles: administration of the basic nursing care, supporting the patients both socially and physically, reporting to supervisor any changes in a patient, and passing any information regarding treatment to a patient. It should be noted that LPNs are not allowed to perform certain duties such as initiation of IV in certain jurisdictions. Depending on the state, there are different strategies and legislations that

Philosophy - Essay Example Although it is not possible to say he describes the absolute truth in his works, the lens he uses to look at history—realism—is one of the most valuable and significant. What was Thucydides’ political philosophy? Simply put, people are not perfect and rarely have the best intentions of the human race in mind when they act, in particular if they are leaders of various countries. Thucydides looked at the characters and conflicts and his time and tried to understand why events happened the way they did. He didn’t act in a hardcore ideological way and he did let his curiosity motivate him, but he had decided views about politics. Although he admired Pericles, he hated demagogues who would rile up the masses and force the country and its leaders to act out of the basest of instincts. All of the issues and problems of politics that this great man came up with and first observed thousands of years ago are with us to this day. We can see the philosophical legacy of Thucydides present in today’s world amongst analysts who look at the world from a position of realism. These people would look, for example, at Russia’s invasion of Afghanistan in 1979, and they would say that Russia’s motives in invading Afghanistan were rooted in self-interests, vested interests, the desire to perpetrate the communist ideology in the whole world, the amassing of more powers that would tilt the balance of power in its favor and against the interests of its Cold War adversary, the United States. To the realist and to Thucydides, expansion of power is often a nation or person’s motivating force and ambition. States and people compete for economic resources and the highest degree of security possible. States value military and economic strength and they are stopped in its tracks only when the level of power of opposing claimants are stronger or just as equal. When analyzing a war—Thucydides
