The Power of Ping-Pong Balls
Being assigned an I-Search paper, I was to acquire a question that was appealing to me, and that I did. It all started after mindless searches via the internet and some procrastination, to which I found myself to be in front of the television. While I knew I should be looking for a suitable question, I still sat there watching on. I happened to be flipping through the channels when a commercial for the Mythbusters brought about the question if one can raise a sunken vessel with ping-pong balls, to which I thought, “Why would anyone want to use ping-pong balls to raise a- hey, that could be my question!” It was so hilariously stupid that it caught my attention, so I used it.
I started my search by contacting my grandfather, John Walker, whom has been a boating enthusiast for his entire life. I asked him if he thought it was possible to raise a boat with ping-pong balls, to which he replied, “Why in the [world] would you want to use ping-pong balls?” He went on to tell me that he had heard a myth saying that a man raised his unfortunate ship using ping-pong balls, made from a factory he worked at. He also told me that to do so, one would have to use a ton of ping-pong balls and that all of the openings would have to be sealed to prevent any balls from escaping. It seemed possible, but I still didn’t have a definitive answer to my question, so I kept on.
After my not-so-definitive interview with my grandfather I used msn.com to search the internet for anything related to the question I had chosen. Doing so lead me to a site which told of a Danish engineer, Karl Kroyer, that had tried to patent such and idea but was denied by the German Patent Office because of an American comic strip which described his idea of using ping-pong balls to raise a ship. This really didn’t answer my question but it did give an idea to where the myth came from. So I went to aj.com where I found a site for The International Starch Institute in Denmark, where it told of Karl Kroyer but not what the first site I visited told of. The site for I.S.I. says that Karl Kroyer was enlisted to raise a two-thousand gross-ton freighter of the Persian Gulf floor and he decided to use a method described in a Donald Duck comic strip.
Many people might think that swinging the bat straight through the ball would be enough to hit the ball a decent distance off the bat. There's many more mechanics involved in the swinging process. Muscle has only a small part to play in the swinging a bat for power. There are two types of mechanics involved while swinging a bat, Linear and Rotational. Rotational mechanics are the dominant source of power in the swing. Out of the rotational mechanics come the two forces that help generate the speed and power of the swing, torque and the other comes from the energy of rotation. Speed from the energy of rotation comes from the path that your hands follow as you swing the bat. The speed generated by the circular rotation from your hands is like a ball at the end of a string, as long as your hands are moving in a circle then the ball continues to accelerate in a circle. So the bat will also move in at an increasing speed as long as your hands are following a circular path as you swing. Any foward movement of the hands or body in a straight line won't add to the overall bat speed.
Another one I feel would be like if you went outside and used the cement, the cracks in the cement, which is due to light and the ground plates underneath the soil, could make the ping pong ball miss the island. I felt that the best ground to use would have been title or polished wood because it gives the ping pong ball enough bounce to at least reach the island.
Author Nicholas Carr’s article “Is Google making us Stupid,” discusses how the use of the computer affects our thought process. Carr starts out talking about his own experience as a writer and how he felt like “something had been tinkering with his brain, remapping his neural circuitry and reprogramming his memory”(313). Basically, he is acknowledging that since he started using the Internet his research techniques have changed. Carr believes that before he would immerse himself in books, lengthy articles and long stretches of prose allowing his mind to get caught up in the narrative or the
Golf is one of the toughest sports there is. The entire goal of the game is to get a very small ball into a cup that is several hundred yards away. What most people may not realize is that physics plays a role in just about every aspect of trying to get the ball into that cup. Every part of the game, from the tee-off until the ball drops into the cup, is affected by physics in one way or another. The purpose of this web page is to introduce you to the role that physics plays in the game of golf.
For a time we used a hickory rake handle (head broken off) for stickball and that thing was a boomah!
Interracial marriage also known as mixed marriage, miscegenation, exogamy, and multiracial, is a marriage between members of different races. It was just 44 years ago that interracial marriage was made fully legal throughout the United States, and it is becoming more common for members to marry outside of ones’ own race. The growth of interracial marriages in the United States corresponds with changes in the legal status of interracial marriages and what some would consider, little, but some changing of arrogance among Americans towards persons in interracial relationships. “Recent increases in interracial unions with Whites presumably reflect positive changes in American race relations as well as the blurring of racial boundaries and racial and ethnic identities” (Batson et al., 2006). The United States 2000 Census Bureau data reports an increase of interracial marriages which contained approximately five percent of all marriages in the Unites States (Forry, 2007). Among the misconception’s relating to interracial relationships people tend to think that the relationship is less successful because of the race difference. However, the true reason behind interracial marriage and relationships being unsuccessful is the lack of communication and clarification of each other’s cultural, and ethnic differences, this can cause a negative impact on the relationship. Notice there was no mention of the relationship being less successful than same-race marriage because lack of and or insufficient communication affects all types of relationships, not just interracial relationships. Many factors are attributed to conflicts among interracial couples. Nevertheless, there are positives aspects of interracial marriage and other ways to make the rel...
First, in mass production the bladder of the volleyball is made by pouring hot rubber into a mold which then molds the hot rubber into the shape of the ball. After this the balls go through a 24 hour inflation test to make sure that the ball holds air up to standards. After the inflation test they cover the bladders in multiple layers of thin nylon thread to help when being made so the rest of the materials that are put on don't slip around as much. Second, after the bladder is made and the nylon is put around it, they put a layer of rubber, a layer of soft composite micro soft leather material, and a surface layer of synthetic laminated rubber. They put all of these layers together on a machine that heat compresses them to make them stick together, except for the very last layer that goes on the outside. The last outside panels are glued on by hand and they are put into a special formation to their desired look. Soon followed they will be tested and later if they pass the tests they will be put into boxes and shipped off to be
Pharmacy as a career brings out a very unique perspective of healthcare system. The healthcare system that is developed in a way to promise a strong bond between people and medicines. This bond thus create the profession of Pharmacy to be a strongest amongst the patients. This ever changing field of Pharmacy has always fascinated me, in a way to think and to observe the community in a base of healthcare system. The path of choosing pharmacy as my profession was unclear before, but my personal background has played a very important role in it. As coming from a different country where healthcare has impacted many lives in a good way and also in a bad way. Also knowing that there are many people in the need of a proper healthcare. As I was growing up, I have seen many people including many kids struggling
Introduction: “Love doesn’t care what language you speak, what colour you are, what religion you believe in, what car you drive, or the amount of money in your bank account, because love has boundaries” –Dabbi. Throughout the years, countries have strived together to end racism with countless commercials, news articles, and social media. Society is given what we want; hope. But as human beings, we want to see change with our own eyes. And we have. Together as a global society we have defeated segregation, apartheid, and diminished the stigma between races. Yet when one passes an interracial couple, thoughts engulf the mind with questions of how and why? Historically, the United States of America has promoted the idea of purity and separation between races. For example, marriages between Caucasians and African-Americans were considered illegal until 1976. Even soon afterward it became legal, there was a prevalent negative stigma attached. But interracial relationships bring amazing concepts such as breaking stereotypes, developing an open mind, and learning about different cultures. In North America, society
Social contact has resulted in an increase in the number of interracial relationships (Ross, 2004). Students’ nowadays are exposed to diverse racial backgrounds than past generation (Jayson, 2011). However, it is difficult for family members to accept such relationships. Family is a vital support system for couples as lack of support from them could be detrimental to the health of such relationships (Tse, Firmin, Hwang & Firebaugh, n.d.). The perceptions of university students towards interracial relationships are yet to be determined. Apart from that, racial stereotyping has profound consequences in the perception of interracial relationships. It is evident that racial stereotyping can leave an impact on relationships (Duke, n.d.). The segregation
Pharmacy, as a profession, is the application of all branches of science to the production of medicinals’ and medicinal products (Shaw et al., 2000, p. 9). Community health, nuclear and retail pharmacy were the areas that I had in mind to pursue. The scope of practice and responsibilities of pharmacists in pharmacy setting differs tremendously either by size of organization or location as there could chain community pharmacy (retail), community health centers, and nuclear pharmacy. Community health centers (CHCs) are private, non-profit, consumer-directed healthcare corporations that provide high quality, cost effective, and comprehensive care to medically underserved and uninsured people (Torres et al., 2002,
During high school, I recall flipping through the pages of my father’s pharmacology textbooks. I was in awe of the abundance of information, and I began to crave knowledge of pharmaceuticals and their systemic targets. Not but a few years later, I began my experience in the field of pharmacy as a drug packer. As soon as I came of age, I applied for my pharmacy technician license – and was promoted shortly thereafter. While my drug and medical knowledge grew, I longed for the opportunity to work directly patients. This innate desire has led me to where I am today: prepared, committed and possessing an aptitude and intellectual maturity required to excel as a pharmacist. I have learned to promote teamwork and professionalism within a pharmacy, take charge in difficult situations, and complete tasks efficiently yet thoroughly. Pursuing a career as a pharmacist would incorporate my passion for pharmaceuticals and their underlying pharmacokinetics with my commitment to promoting health and well-being within my community.
Branching off from our last article, the game of volleyball itself was invented in 1895, and almost at once it swept around the world; not only as an official sport, but also as a pastime that could be described as one of the “crazed” varieties. Well, it didn’t just stop there; volleyball eventually made its way outdoors, to the beach!
It all began as a lawn game similar to the croquet played sometime during the 15th century in Northern Europe and probably in France and has evolved from that point into present day's style of billiard/pool table and rules. Playing the game moved indoors to a wooden table with green cloth to simulate grass, and a simple border was placed around the edges. The balls were shoved, rather than struck, with wooden sticks called "maces." The term "billiard" is derived from the French language, either from the word "billiart", one of the wooden sticks, or "bille", a ball” (Pool Tables). The story of how billiards came to be has unique qualities such as the way the term “billiards” came to be.
