Physical Education and Human Biology Research Paper Example

Physical Education and Human Biology Paper While studying Physical Education and Human Biology at A level, my passion in sport and its relation with the human body has continued to grow and develop. As a keen sportsman I want to develop a career in the sports industry, using the knowledge gained through study to enhance my opportunities in this exciting area. I have also become more and more interested in the multiple factors influencing the performance of a person engaged in sport, from an occasional participant, through to club level and onto elite level athletes. These are factors that we have been investigating in detail through A level Physical Education. Studying Chemistry and Human Biology at A Level has developed my practical skills further, as a result of the many and varied experiments conducted in the laboratory. Additionally, I have gained valuable analysis and evaluation skills through this practical work, due to the need to analyse and evaluate the data retrieved from experiments, and interpreting this data into a meaningful conclusion. Human Biology has allowed me to expand my knowledge of the human body in many different ways, including how the human body operates, the factors which can influence it, and the way it responds to exercise.

The continued study of these subjects will enable me to better understand success factors, which can mean the difference in performance between two similar athletes. Furthermore, expertise in these areas will help me to understand how to leverage these different influences to achieve improved performance. As an active member of my local Squash Club, I am involved in the committee, helping organise league matches, tournaments and external match competitions with other clubs. This has proved to be valuable experience in terms of learning to organise, communicate and run different types of events, whilst being a committed player myself. Other sports I am interested in include swimming, tennis and mountain-biking. My general interest in various sports has given me an insight into their discrete demands, their conception, and their physical and mental requirements. I have come to understand, however, that there are fundamental scientific principles which are the same for all sports. Recently I spent two weeks with French friends in France, and discovered that my interest in sport has been a useful way of meeting new people and improving my language skills. As a result my French has significantly improved. I have developed other skills that will benefit me at university through part-time work at my local supermarket. These involve serving and interacting with customers, cash handling, working with others as part of team and the need for efficient and effective work. I have received several shining stars from my employers in recognition of my part in the success of their operation. Continued study in the field of Sports and Exercise Science will be a challenge that I look forward to as I am determined to further develop my understanding with a view to pursuing a successful career in the Sports Industry. Studying at university will help build and develop the skills I have gained to date and will enable me to make an informed decision about which specific career path I wish to pursue.

Learn Whether Cloud Seeding Can Kill Hurricanes

Learn Whether Cloud Seeding Can Kill Hurricanes Efforts at storm modification date back to the 1940s, when Dr. Irwin Langmuir and a team of scientist from General Electric explored the possibility of using ice crystals to weaken storms. This was Project Cirrus. Enthusiasm about this project, combined with devastation from a series of hurricanes that made landfall, prompted the U.S. federal government to appoint a Presidential Commission to investigate storm modification. What Was Project Stormfury? Project Stormfury was a research program for hurricane modification that was active between 1962 and 1983. The Stormfury hypothesis was that seeding the first rain band outside of the eyewall clouds with silver iodide (AgI) would cause supercooled water to turn into ice. This would release heat, which would cause the clouds to grow faster, pulling in air that would otherwise reach the wall of clouds around the eye. The plan was to cut off the air supply feeding the original eyewall, which would cause it to fade away while a second, wider eyewall would grow further from out from the storms center. Because the wall would be wider, air spiraling into the clouds would be slower. The partial conservation of angular momentum was intended to decrease the force of the strongest winds. At the same time the cloud seeding theory was being developed, a group at the Navy Weapons Center in California was developing new seeding generators that could release large amounts of silver iodide crystals i nto storms. Hurricanes That Were Seeded With Silver Iodide In 1961, the eyewall of Hurricane Esther was seeded with silver iodide. The hurricane stopped growing and showed signs of possible weakening. Hurricane Beulah was seeded in 1963, again with some encouraging results. Two hurricanes were then seeded with massive quantities of silver iodide. The first storm (Hurricane Debbie, 1969) weakened temporarily after being seeded five times. No significant effect was detected on the second storm (Hurricane Ginger, 1971). Later analysis of the 1969 storm suggested that the storm would have weakened with or without the seeding, as part of the normal eyewall replacement process.​ Discontinuing the Seeding Program Budget cuts and lack of definitive success led to the discontinuation of the hurricane seeding program. In the end, it was decided that funding would be better spent learning more about how hurricanes work and in finding ways to better prepare for and lessen the damage from natural storms. Even if it turned out cloud seeding or other artificial measures could lessen the intensity of the storms, there was considerable debate about where on their course the storms would be altered and concern over the ecological implications of changing the storms.
