Aerodynamics of Golf Balls :: physics sport sports golf

Introduction to Aerodynamics Aerodynamics is the study of the motion of fluids in the gas state and bodies in motion relative to the fluid/air. In other words the study of aerodynamics is the study of fluid dynamics specifically relating to air or the gas state of matter. When an object travels through fluid/air there are two types of flow characteristics that happen, laminar and turbulent. Laminar flow is a smooth steady flow over a smooth surface and it has little disturbance. Intuition would lead to the belief that this type of air flow would be desirable. It would make sense to assume that this smooth undisturbed air would create the least amount of resistive force due to friction. The golf ball seemingly defies this theory by traveling farther with its disruptive surface texture that creates the second flow characteristic, turbulent flow. Turbulent flow is flow that is disturbed and creates whirlpool like features. The turbulent air actually lessens the difference in velocity of the air layer that is extremely close to the ball compared to the rest of the air and so lessens the friction acting on the ball. Drag is a major contributor to how an object travels through fluid/air. Drag is caused by the disrupted air immediately behind an object moving through fluid/air. It acts perpendicular to and in the opposite direction of travel of the object and impedes the motion of the object. It would make sense that if the drag is minimized the object will travel farther. Lift or curve in the motion of an object through air is a phenomena that is noticeable in a ball traveling through fluid/air. This change in direction is due to the effect that spin has on the object in motion. This can be explained by Bernoulli's Principle. Bernoulli, a 1700's physicist and mathematician, showed that the speed of an object through liquid/air changes the pressure of the air. The velocity of a spinning ball relative to the air is different from one side to the other creating a low pressure on one side and a high pressure on the other. This causes the ball to move in the direction of the lower pressure. The golf ball is typically hit with an undercut causing a reverse rotation and therefore a lifting action on the ball. The History of Golf Balls The golf ball has changed dramatically through the years. Smooth hardwood balls were used between the 1400 and 1700's.

Brindis Speech

The speech was Rizal’s toast to the triumph of Juan Luna’s Spolarium and Felix Hidalgo’s Las Virgenes Cristianas Expuestas al populacho in their work of arts whose works illuminates two ends of the globe: East and West (Spain and the Philippines). It’s about the acknowledgement and thanking them for the pride and glory they gave to the Filipinos. But most of all, he gives praise to those youth’s actions that can make a difference and contribute to the glory of the Philippines.He wanted to make the people realize that glory doesn’t based to a country alone. What he wanted to prove is that geniuses bloom and sprout all over the world with its own uniqueness, talents, and intelligence. No one needs to have same culture and the greatness of a country, but the real talent comes to their works. What he takes jab are elites who does everything just to stop the education system among filipinos because they are afraid that they might learn to defend.I n the speech he made, there are values and lessons he teach us that can be applied in a real world up until now such as mentioning geniuses can be born and made anytime and anywhere. No one has the right to judge or put down a person because anyone can be great. He also said that Spain and Philippines are equal, no greater nor slaves. Dr. Jose Rizal is great because he discussed bravely what the Spaniards are afraid of: EDUCATION of the filipinos but what he focused more is to inspire filipinos and prove how worthy a nation can be.

The Statue Of Liberty At Ellis Island - 991 Words

America is a melting pot of culture. The statue of liberty at Ellis Island has welcomed hundreds of thousands of immigrants into this country since the early 1900s. Although the immigrant families knew it was important to learn the American language and American culture, they also wanted to keep alive their rich heritage and pass it onto their children. This was often a struggle as their children attended American schools and picked up on the American culture ways quicker than their elder parents. Often these children, especially the teenagers, would struggle with embarrassment over the ways their family was different from other American families. One author who wrote about this struggle was Amy Tan. What readers appreciate about Amy†¦show more content†¦This was what inspired her to write stories about the relationships between Chinese women and their Chinese-American daughters. In the narrative â€Å"Fish Cheeks†, Amy Tan shares a story of young love which reveals the conflict of shame and pride that she felt about her Chinese heritage. The narrative begins by telling how a young Chinese girl has a crush on the minister’s son, Robert who is American. When the daughter finds out her parents have invited the minister and his family over to eat, she starts to panic. All she could think was, â€Å"What would Robert think of our shabby Chinese Christmas? What would he think of our noisy Chinese relatives who lacked proper American manners? What terrible disappointment would he feel upon seeing not a roasted turkey and sweet potatoes but Chinese food?† Here is where Amy Tan first hints at the shame she has about her culture. She was already embarrassed before the dinner even happened. Tan continues to provide a vivid image of the special meal her mother has prepared. For example she describes the fish as â€Å"a slimy rock cod with bulging eyes†, and she makes the fish seem almost human as it â€Å"pleads† not to be dropped into the hot oil. Tan uses a simile to describe the tofu. â⠂¬Å"Tofu, which looked like stacked wedges of rubbery white sponges.† Tan compares the markings on the squid to a bicycle tire, so that one can imagine the deep cuts made by the knife. She includes this description

EVIDENCE BASED PRACTICE INTRODUCTION: Evidence-Based Practice (EBP) is a thoughtful integration of the best available evidence, coupled with clinical expertise. As such it enables health practitioners of all varieties to address healthcare questions with an evaluative and qualitative approach. EBP allows the practitioner to assess current and past research, clinical guidelines, and other information resources in order to identify relevant literature while differentiating between high-quality and low-quality findings. UNIT BACKGROUND: Evidence based practices was founded by Dr.Ardice Cochrane , a British epidemiologist.Cochrane was a strong proponent†¦show more content†¦Problem focused triggers are identified by healthcare staff through quality improvement,risk surveillance,benchmarking data,financial data, or recurrent clinical problems.Problem focused triggers could be clinical problems,or risk management issues. Example:Increased incidence of deep vein thrombosis and pulmonary emboli in trauma and neurosurgical patients.Diagnosis and proper treatment of a DVT is a very important task for health care professionals and is meant to prevent pulmonary embolism.This is an example of an important re tht more research can be conducted to add into evidence –based practice. Knowledge focused triggers are created when health care staff read research, listen to scientific papers at research conferences.Knowledge based triggers could be new research findings that further enhance nursing ,or new practice guidelines. Example: Pain management .,prevention of skin breakdown , assessing placement of nasogastric tubes, and use of saline to maintain patency of arterial lines. When selecting a question ,nurses should formulate questions that are likely to gain support from people within the organization.The priority of the question should be considered as well as the sevearity of the

Jean Arp Essays - Dada, Art Movements, Jean Arp, Tristan Tzara

Jean Arp ?Art is a fruit that grows in man, like a fruit on a plant, or a child in its mother's womb,? once commented Jean Arp--a remarkable twentieth-century sculptor, painter and poet associated with and a forefather of the Dada and Surrealist movements. The avant-garde artist was born on September 16, 1887 in Strasbourg, France, where he studied at the Ecole des Arts et M?tiers. In 1905, he transferred to the Weimar Academy and then to Paris at the Acad?mie Julian in 1908, and subsequent to graduation resumed his painting in Weggis, Switzerland in isolation. By 1912, Jean Arp had become associated with the Blaue Reiter, or Blue Rider, a group of Expressionist artists in Munich, where he exhibited ?semi-figurative? drawings and became well-acquainted with fellow artist Wassily Kandinsky. In 1913, he exhibited with another group of Expressionists at the first Hebrstsalon--or Autumn Salon, an art exhibition--in Berlin. Aware of the developments within the French avant-garde through his contacts with such artists as Apollinaire, Max Jacob and Sonia and Robert Delaunay in 1914, Arp presented his first abstracts and paper cutouts in Z?rich in 1915 and arranged his first shallow wooden reliefs and compositions of string nailed to canvas. In 1915, the art of Jean Arp consisted of abstract and angularly patterned tapestries and drawings, but soon matured as he became the co-founder of the revolutionary Dadaist school of artists in Z?rich, Switzerland with Tristan Tzara and Hugo Ball. His familiar abstract and curvilinear forms debuted in 1917, and in 1919 he continued his Dadaist portrayals with Ernst in Cologne before participating in the Berlin Dada exhibition of 1920. Jean Arp married Sophie Tauber in 1922, during a period where he was most notable for his painted wooden bas-reliefs and humorous cut-cardboard constructions. He settled with his wife at Meudon in 1927, when he participated in the Surrealist movement and had his first one-man exhibition at the Galerie Surr?aliste in Paris. He then parted with Surrealism to become a co-founder of Abstraction-Creation in 1931, when his characteristic organic forms became more severe and geometrical. In the 1930s, Jean Arp began to work in freestanding sculpture, carving and molding a variety of substances. An example of his smooth, biomorphic forms is the marble Human Concretion, 1935, located in the Mus?e National d'Art Moderne in Paris. Arp was tenacious in correcting art critics as to the nature of his sculptures; he insisted that his pieces were ?concrete? rather than ?abstract?, since they occupied space, and that art was a natural generation of form--?a fruit that grows in man?, as he had stated. Jean Arp visited the United States in 1949 and 1950 to finish a monumental wood and metal relief for Harvard University; in 1958, he composed a mural relief for the UNESCO Building in Paris. He was awarded the international prize for sculpture at the Venice Biennale in 1954 and the 1964 Pittsburgh International. Arp died on June 7, 1966 in Solduno, Switzerland, survived by his second wife, Marguerite Arp-Hagenbach. A dominant personality within abstract art, Dada and Surrealism, his reliefs and sculptures have had a decisive influence upon the sculpture of this century.
