Golf Physics Essays - Classical Mechanics, Rotation,

Golf Physics As anyone who has played a round of golf will attest to, the sport is based around many fundamental principals of physics. These basic laws are involved with every aspect of the game from how a player swings the club to how the ball moves through the air on its way toward the pin. It is the challenge that physics presents to the golfer that has allowed the game, and equipment used, to develop so drastically over the past one hundred years. The first golf balls used were called featheries. They were made with a horsehide cover packed with wet goose feathers. When the balls dried they became extremely hard. The major flaw with the featheries was that they could not be used when the conditions were wet because they would soften again.[5] Despite the flaw of the featheries, they remained the only ball used up until the middle of the 19th century when the revolutionary gutta-percha ball was invented. The new ball, sometimes referred to as a "guttie", was molded from the warmed, dried gum of the sapodilla tree.[5] These balls were cheap to manufacture and opened up the game of golf to a more diverse socio-economic group. This in turn made the game of golf very popular, which led to dramatic improvements in golf balls in the next decades. In 1900 a unique event occurred. Some claim that it can be called the first professional sports endorsement. The Spalding Company paid England's Harry Vardon a considerable sum of money to come to the United States to demonstrate what he could do in winning tournaments using the latest ball design. He won the U.S. Open using the new rubber-wound Haskell ball.[5] This led to another major revolution in the design of the golf ball. Not only was this ball cheap to manufacture, but also it could be hit farther than any other ball previously used. The Haskell ball was such a success that it was not until 1968 that the two-piece balls of today emerged in the market. Obviously a lot of time, effort, research, and money were put forth into the development of the golf ball, as it is manufactured today. The reason for this ongoing process is to help a golfer use some laws of physics to his advantage (i.e. placing spin on the ball to create lift) while finding a work around for other physical properties that can be detrimental to a players golf game (i.e. drag which causes the ball to slow down and fly closer to the ground). When examining the physics, which surrounds the game of golf, one must carefully consider all aspects of the game, not just the golf ball or even just the equipment being used. The stroke is by far the most important aspect to any participants round of golf. Among the scientific community, an event, such as the golf stroke, is thought of as a dynamic process using the physical principals of mechanics based on Newton's Laws of motion. The stroke is actually three separate events; the swing of the club, the impact of the club head with the ball, and the flight of the ball toward the target. It is the sum of these three parts that makes a successful stroke. Before delving into the details of the golf stroke, it is important for one to consider the general concepts of motion that control the swing of the golf club. Two men are most influential in this area of study, Galileo Galilee and Isaac Newton. It is the principles of these two men that will be used during the discussion of the physics of golf. A brief explanation of momentum, moment of inertia, torque, centripetal force, and centrifugal force can be located in "Appendix 4". These terms were derived from the experiments and research of first Galileo, and then expanded upon by Newton. Although neither of these two men are solely responsible for all of the physical principals presented in this paper, Galileo and Newton were two of the most influential men in these areas of study. When a scientist attempts to explain something, he or she always develops a model to work with. In the case of the golf stroke, it has become evident that comparing such an action to the snapping of a whip lends itself nicely to a deeper understanding. The model appropriate to the study of a whip, such as a bullwhip, would be a large number of small rods with flexible connections. This is important to understanding

Definition and Examples of Vogue Words

Definition and Examples of Vogue Words A vogue word is a fashionable word or phrase that tends to lose its effectiveness through overuse. Also called a  voguism. Vogue words, says Kenneth G. Wilson, are perfectly good Standard English words that suddenly become modish, so that for a time we hear them being used everywhere, by everyone, until we are utterly sick of them (The Columbia Guide to Standard American English, 1993). Examples and Observations [Some] vogue words are technical words clumsily applied to other fields. These include parameter, bottom line, interface, mode, and space; phrases like immediate feedback and close the loop; and, in a sense, ballpark figure, and touch base with you.(Matt Young, The Technical Writers Handbook: Writing With Style and Clarity. University Science Books, 2002)IconicMr. Leopold is not turning 95 years old, but his iconic ice cream business is. . . .Now owned by Peters youngest son, Stratton, and his wife Mary, the iconic sweets shop on Broughton Street still serves its premium recipes in a fun, retro-style soda shop. . . .She says they plan to offer plenty of room for guests to find a seat while hot dogs will be for sale and the iconic Leopolds portable carts will be on hand outside the store.(BDay Bash: Leopolds Celebrates 95 Years. Savannah Morning News, August 14, 2014)ArtisanThere are, I think, two ways one could read the fact that McDonalds is using the word  artisan  to market it s chicken. On the one hand, it could be a self-aware joke meant to finally deal a death blow to one of the most grating words in the pop lexicon. The king of mass-produced fast food has officially appropriated a phrase that once denoted something expensive and handmade, thus rendering it fully devoid of meaning. In which case: McDonalds 1, upper-middle-class foodies 0.The other possibility: The chain is struggling to  reverse its sales woes, and bewildered by the brave new world ushered in by Shake Shack and Chipotle, it has latched on to artisan as an inadvertently desperate-sounding synonym for less industrial.†(Jordan Weissmann, McDonald’s, Bewildered by Modernity, Is Now Selling an Artisan Chicken Sandwich. Slate, April 27, 2015) Favorite and Least Favorite Words: Awe and Awesome!- Awe, a word we are about to lose, that has been robbed of its meaning by the unfortunate adjective awesome. Awe meaning ecstatic, reverential feeling before Beauty, before the Magnificent. Awesome, a tiresome word, flung indiscriminately in all directions, on all occasions until it has become so trivial, it is valueless.Awe, to be used on rare occasions before the marvelous, the extraordinary. It conveys wonder and amazement. Even the sound conveys a feeling. Saying the word, the mouth opens in speechless delight before that which is greater than the self.(Elizabeth Strong-Cuevas, quoted by Lewis Burke Frumkes in Favorite Words of Famous People. Marion Street Press, 2011)- In a world of sensory overload, most terms of acclaim are exaggerations. A pile of french fries hardly makes us tremble in awe, yet we call it awesome, exaggerating for the sake of persuasion. But because awesome is so worn out, the exaggeration doesnt register; it needs an element of novelty to help it to do so. Novelty gets attention. The fries were industrial-strength awesome. The ride was shiver-me-timbers awesome.(Arthur Plotnik, Better Than Great: A Plenitudinous Compendium of Wallopingly Fresh Superlatives. Cleis Press, 2011)- Im just amazed that hundreds of people can gobble up this malarkey and repeat it, with straight faces. Im equally amazed by the high regard in which HubSpot people hold themselves. They use the word awesome incessantly, usually to describe themselves or each other. Thats awesome! Youre awesome! No, youre awesome for saying that Im awesome!(Dan Lyons, Disrupted: My Misadventure in the Start-Up Bubble. Hachette, 2016)- Vogue words like  awesome  catch on because everyone is using them, and they irritate because everyone is using them. Adopters hear other people using  awesome  to indicate enthusiastic approval generally and pick it up because it gives them a sense of solidarity and group identity. Scorner s resist  awesome  because they do not care to sound like those people.Acceptance or rejection of group identity sharpens the reactions.For example, sticklers will likely carp about impoverishment of vocabulary and semantic drift,  awesome  in the enthusiastic approval generally sense having little or nothing to do with  awe  (just as they would previously have objected to  terrible  for its attenuated connection to  terror). For the stickler, disapproval is a badge of cultural and social superiority. For the adopter, approval is a thumb in the eye of the pretentious.(John E. McIntyre, Shock and Awesome. The Baltimore Sun, December 23, 2015) ViableViable means workable and likely to survive. It has become a vogue word and is commonly used in the sense of workable or achievable. Adjectives such as durable, lasting, effective, and practical are more appropriate.(James S. Major, Writing Classified and Unclassified Papers in the Intelligence Community. Scarecrow Press, 2009)Associate You walk into a PetSmart, a supermarket for dog and cat supplies that allows customers to shop along with their animal companions. You hear a voice on a loudspeaker say urgently, Would an associate report to the rubber-toys aisle. Instantly, a guy with a mop and pail appears, zeros in on the puddle behind a shamefaced puppy and takes care of the problem.The job title of the person doing the mopping-up is associate. No longer is today’s man with a muck rake termed an employee; that description is deemed demeaning. Associate hints at managerial equality.(William Safire, On Language: Vogue-Word Watch. The New York Times, July 15, 2009)Unacce ptableWhy is everyone using the word unacceptable lately? An irate woman on Five Live phoned in this morning and said that it was completely unacceptable that the banks were gambling with our money.Tonight, on East Midlands Today, after a disturbing report about a sawn-up body found in a wheelie bin in a Nottingham suburb, a policeman said, This is a quiet residential area and, as such, this crime is totally unacceptable.A neighbour who was interviewed in the street said, I noticed the bin had been out on the pavement for three days, which is obviously unacceptable.(Sue Townsend, Adrian Mole: The Prostrate Years. Penguin, 2010) ImageA great darling among the loosely used pseudoscientific vogue words of recent years is image in the sense impression that others subconsciously have of someone. A jaundiced observer of modern life might well suppose that what we actually are is not nearly so important as the image we are ableto use another vogue wordto project.(John Algeo and Thomas Pyles, The Origins and Development of the English Language, 5th ed. Thomson, 2005)FeedbackFeedback. In its rigorous scientific sense, feedback is the return to an input of part of its output, so as to provide self-corrective action. Feedback is a vogue word in a loose sense for which response would be a perfectly adequate alternative, as in we got a lot of valuable feedback on our advertising campaign.(Ernest Gowers, et al. The Complete Plain Words, rev. ed. David R. Godine, 1988)How to Resist Vogue WordsThe best way to offset the harm of vogues is to stick resolutely, in speech and writing, to each vogue words central meaning. Addre ss an audience or a postcard, but not a problem or a question. Call a substance or a temperament volatile, but not an issue or a situation. Express sympathy far and wide, but keep empathy for aesthetics or psychiatry. Remember Tiny Tim and avoid naming things minuscule or minimal.(Jacques Barzun, Simple Direct: A Rhetoric for Writers. Harper Row, 1975)

Case Study Essay Example | Topics and Well Written Essays - 1000 words - 24

Case Study - Essay Example The owner has differing opinions on the paint coats to be done on the steps and the house. The double standards allow for the establishment of a clout of dispute in the ideal description of the term. However, the owner and the contractor had an agreement on the observation of a first-class job. Such an agreement allows for the presentation of the considered concerns as an argument of relevance. Apparently, the owner is rather prone gain from the ruling since the contract did not consider defining the elements of a first-class paint work. Regarding the second concern, the ruling will focus on the contract binding the two parties. The steps are not considered to be part of the house. Apparently, both the owner and the contractor seem to concede that indeed the item is not in the contract irrespective of being pointed out during the negotiation phase. Such an observation implies that the ruling over the matter will most probably be perceived to be in favor of the contractor. The owner may be advised to consider establishing another contract in quest of including the considered steps. Regarding the second case, the phrase â€Å"Alternatively, if flooding, jetting and vibration are to be used for placing and compaction, the material shall meet the additional requirements specified in paragraph zone 1 and zone 2 Bedding Material for material to be placed and compacted by flooding, jetting and vibration. The maximum size shall pass a 2-inch U.S. Standard Series sieve† allows an advisory path for the ruling. The final statement in the phrase allows for the compliance with the 2-inch test. It is not hinged on the initial consideration on compacting capacity. He verdict will thus favor the coontracctor. The owner may reflect on the Buchanan v. Martin Marietta Corp., 494 A.2d 677 and Schiavi v. Goodwin, 542 A.2d 367 (Klass, 2012) that points on the possible aspects upon which interference to the contract may be considered. The

What are the advantages and disadvantages of EDCT's You Essay

What are the advantages and disadvantages of EDCT's You - Essay Example In such case, the airline company has to be assigned again with a new EDCT which maybe much later than the other airplanes. This is due to the fact that the issuance of EDCT’s is on the â€Å"first come, first serve basis.† Hence, the passengers may become upset and feel frustrated on the transport service of the airline company due to extension of holding time. Considerably, an airplane company may opt not to fly in accordance with the EDCT for the reason that they only have few passengers aboard and it will expectedly result to an unfair loss of profits. On the other hand, the assigning of EDCT’s significantly helps the air traffic controllers to accurately accept or deny any suggested arrivals or departures by airline companies. This allows them to regulate the air traffic more efficiently and orderly (FAA 21). On the contrary, the assignment of such adds burden to the work of the air traffic controllers. The air traffic controllers are expected to be attentiv e and available at all times. In fact, in times wherein there is a continuous weather disturbance, they are forced to work overtime just to ensure the safety departure and arrival of

The human digestive system

The human digestive system The human digestive system is responsible for the intake, breakdown, absorption and finally removal of nutrients and energy needed for the functioning of the human body. It performs these duties by allowing nutrients and energy in the form of food to enter the body, and then removing the materials needed from the food, then absorbing the materials into the body, as well as sending these materials to the place that theyre needed, and finally removing the leftover materials from the body. The system consists of the primary organs; the mouth, the esophagus, the stomach, the small intestine, the large intestine, the rectum, and the anus, as well as the secondary organs; the liver, the salivary glands, the gallbladder and the pancreas. The mouth is responsible for the immediate intake of food, and is partially responsible for digestion, through the process of mastication, which is the chewing of food. Food enters the body through the mouth, where it is than chewed to soften and partially breakdown the food. Saliva from the salivary glands also aides in the preliminary breakdown of foods, because of the chemicals and enzymes contained in saliva. Once the food is sufficiently broken down, it is swallowed and brought to the next organ in the digestive system, the esophagus. The Role of the esophagus is simply to allow the partially broken down food to travel from the mouth to the stomach. Its role in digestion is minimal, but it is still considered one of the major organs in the system. At the joining point of the esophagus and the stomach, called the cardiac sphincter, is the blocker that prevents gastric acid from exiting the stomach and damaging the mouth or the esophagus itself. When the Cardiac sphincter fails its job, the gastric acid seeps into the esophagus, causing damage to the interior of the esophagus, as well as the painful sensation known as heartburn. The stomach is a muscular, hollow organ in the human digestive system, and is one of the primary sites of digestion. It is filled with gastric acid, a powerful acid that breaks down food with relative ease, digesting most foods in about 4 or 5 hours. The stomach contains three glands, which are used to either aid in the digestion of food, or protection of the stomach from its own digestive materials. The three types of glands are the pyloric gland, the cardiac gland and the gastric gland. The pyloric gland is responsible for secreting gastrin, a hormone which stimulates the production of gastric acid. The gastrin activates the gastric glands, which start secreting gastric acid. The cardiac glands are the centers of mucus secretion in the stomach. This mucus is used to protect the lining of the stomach. A common problem associated with the stomach is peptic ulcers, a type of ulcer formed by a disturbance in the regulation of the hormone gastrin, which causes to much gastric acid to be produced, which causes damage to the mucus membrane and the stomach lining. After food has been digested enough, it moves out of the stomach and into the small intestine. Another round of digestion occurs in the small intestine, even more than in the stomach. Absorption also begins to occur at this stage in the digestive system. The small intestine is broken down into three parts, the duodenum, the jejunum, and the ileum. The duodenum is the first part of the small intestine, and it is responsible for most of the food digested in the small intestine. The duodenum also regulates the rate of emptying of the stomach via hormonal pathways. The next part of the small intestine is the jejunum, which is the longest portion of the small intestine, but it is also responsible for very little digestion, but is primarily responsible for the first round of absorption, where it takes most of the nutrients out of the food matter. The final portion of the small intestine is the ileum, which is where the final bit of absorption in the small intestine takes place. Once the now digested material finishes its path through the small intestine, it enters the large intestin e. The large intestines primary purpose is to remove most of the water from the now indigestible mass, and move it to the anus, where it will be removed from the body. The large intestine is made up of the cecum, the rectum and the colon. The cecum is not very large in humans, and is barely existent at all. It serves a much higher purpose in herbivores, where it digests tough leaves with the help of symbiotic bacteria. In humans this is not necessary, so it has become very unimportant. The colon is where the water is taken from the digested food matter. The rectum is where the waste is temporarily stored before it is excreted from the body, which takes place in the anus. The secondary organs in the digestive system are also vital to the survival of a human, but they take a more passive role in digestion. The liver plays a major role in digestion and has a number of functions, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. It lies below the diaphragm in the thoracic region of the abdomen. It produces some of the systems bile the rest is produced by the gallbladder, an alkaline compound which aids in digestion. It also performs and regulates a wide variety of high-volume biochemical reactions requiring highly specialized tissues, including the synthesis and breakdown of small and complex molecules, many of which are necessary for normal vital functions.

Movie The Matrix Essay example -- Movie Film Matrix Films Essays

Movie The Matrix In 2002, Brent Staples communicated with Jean Baudrillard about the use of his philosophy in The Matrix (1999), a film written and directed by Andy and Larry Wachowski. Staples wrote, â€Å"He [Baudrillard] noted that the film’s â€Å"borrowings† from his work â€Å"stemmed mostly from misunderstandings† and suggested that no movie could ever do justice to the themes of this book†. In this paper, I will argue that the Wachowski Brothers did not want to â€Å"do justice to the themes of this book†; they wanted to adapt Baudrillard’s theories about the blurring of the real and unreal, and the eventual extermination of the real, into a story that provides hope for humans wanting to escape the suffocation of the â€Å"hyperreal†. The â€Å"hyperreal† was first coined by Baudrillard in his book, Simulacra and Simulations (1983); it is the product of the distortions of the real through endless simulations of it in radio, newspaper, te levision, and film. In The Matrix, Morpheus offers Neo one more opportunity to accept the â€Å"hyperreal† in the form of a blue pill which alludes to a world of fantasy, a world that has imprisoned the real—this world is known as the matrix. Many people, like Neo, might ask "what is the matrix?" Whether they would be ready, or not, Morpheus will tell them, â€Å"The Matrix is the world that has been pulled over your eyes to blind you from the truth†. The truth â€Å"that you are a slave†, â€Å"like everyone else you were born into bondage, into a prison that you can’t smell, or taste, or touch; a prison for your mind†. This prison is built not necessarily to keep you from being free, but to keep you from the real. The prison’s simulations of the real are so precise that they fool thousands of people in The Matrix. However, there... ... the matrix. Neo speaks of a simulation that produces redundancy, a simulation that fears change and evolution, and finally a system that allows no progression of human thought. Neo and his band of revolutionaries are now set on awakening as many people as possible from this banal, fake existence. An existence that has produced the stagnation that the Wachowskis feel humans have been born into. There is meaning to be found in life, and for the renegades in The Matrix, meaning is reality. The Wachowskis, and those liberated from the programmed world, see the perpetual simulations and the machines responsible for them as enemies. The enemies of reality are accountable for the traditional cultural suffocation of the real, progress, inspiration, dreams, and individuality. The Matrix and its creators take the position that no amount of this suppression is acceptable.

Psychology Ia Notes

Psychology Summer Assignment 2011 Due first class back in August/ September: Draft of Introduction and Design of Psychology Experiment. HL Psychology: IA is graded out of a score of 28. It is worth 20% of your final grade. 1500-2000 words SL Psychology: IA is graded out of a score of 20. It is worth 25% of the Final Grade. 1000-1500 words Refer to the IB Guide for First Exams in 2011 as you write your paper, and keep in contact with me. Here is a website from which you can download the Psychology Guide: http://www. bsurvival. com/files/file/1134-psychology-guide-for-first-examinations-in-2011/ Here are the parts of the IA that you must submit in our next class in August: Introduction (5 points HL; 2 points SL)) Method: Design (2 points for SL and HL) Method: Participants (2 points for SL and HL) Method: Procedure (2 points for SL and HL) Key advice: NUMBERS: Make sure that you choose an experiment that has results that can be measured on a broad scale. So observers in Bandura were not told to rate violence on a â€Å"yes† or â€Å"no† basis, but to count the number of violent acts; Milgram had many intervals on his â€Å"shock machine† that enabled him to measure and compare statistics about what point people would drop out at; Loftus and Palmer asked participants to estimate speeds in miles per hour, as opposed to â€Å"were they going fast or slow. † You will be calculating statistics and showing trends. The more detailed the numbers, the more you can say about them. And nearly half of your IA grade will be based on what you do with these numbers. ETHICS: Refer closely to the Guide as you prepare. PARTICIPANTS: there are many characteristics of participants that can be considered confounding variables. You should know your experiment well enough to avoid these. DESIGN: Repeated measures or independent samples. The answer to which one you choose is always logical, but you must show that you understand the logic. METHOD: It must be possible for the reader to replicate your study based on what you write. A word of encouragement: You should be carefully selecting the experiment that you will replicate over the summer. I have asked for a draft of the first parts of the paper to get you to start writing in the IA style. If you over the summer you find that you cannot write about your experiment, you will still have time to choose another one. I will be available throughout the summer through emails, and at times through Moodle, so keep in touch. The IB says that you must have 30 hours (SL) and 40 hours (HL) of class time devoted to the IA. I prefer to use this time to work on how to do the experiment, express the results, debate the conclusions. But for that, you need to get through the simplest processes on your own. Every one of you is capable of a grade of â€Å"5† if you are diligent. And once you know you have an IA grade of â€Å"5,† you'll have renewed confidence and motivation to get through the final months of the course. Due Dates: First Draft (all parts) by October 20 (last class before the Toussaint break) Papers will be returned with comments and advice after the Toussaint. Final Draft: IB and Ermitage approved deadline is December 10. This information can also be found on your Moodle Y1 Psych site.
