...The Physical Science of Skydiving Vanessa Laine Gabriel Dr. Burkeen Westwood College The Physical Science of Skydiving Introduction Skydiving which is also known as parachuting, is the action and adventurous sport in which a volunteer exit takes place from an aircraft for returning back to earth with gravity aid with the help of parachute for slowing down throughout the last of the safe descent of earth. This action may or may not comprise of a specific amount of free fall, but a moment in which the parachute has not been set out and the body accelerates gradually to terminal velocity. In this paper, a discussion will be conducted on the physical science of the skydiving. Skydiving is performed as a competitive sport and a recreational activity, as well as it fulfill the deployment of the Airborne forces’ military personnel and rarely forest firefighters. When a parachute opens as, that will be completely inflated by 2,600 feet or 800 meters, (BBC News, 2009) and then the skydiver can control the speed and direction with toggles on the steering lines’ ends that are linked to the parachute’s trailing edges, and can intend for a safe landing and eventually arrive to a moderately tender stop. All the contemporary sport parachutes have ‘ram-air’ wings that are self-inflating and assist in controlling the direction and speed as per the linked paragliders. Purists in every sport would signify that paragliders have highly superior range and lift, but that parachutes are specially...

... * Top: Baroque drawing of the constellation Orionfrom Johannes Hevelius' celestial catalogue * Bottom: Contemporary map of Orion from the IAUand photography of the night sky | In everyday usage, a constellation is a traditional or recognizable group of stars in the night sky, or the region of the sky containing them. In technical usage these meanings have been separated, with groupings of stars being called asterisms, and the word constellation being reserved for a specific area of the celestial sphere with boundaries laid down by the International Astronomical Union (IAU). These areas mostly had their origins in Western-traditional asterisms from which the constellations take their names. When astronomers say something is “in” a given constellation they mean it is within those official boundaries. There are 88 officially recognized constellations, covering the entire sky[1] which have grown from the 48 classical Greek constellations laid down by Ptolemy in the Almagest. Out of these 88 constellations, 12 compose the zodiac signs. Thus, any given point in a celestial coordinate system can unambiguously be assigned to a constellation. It is usual in astronomy to give the constellation in which a given object is found along with its coordinates in order to convey a rough idea in which part of the sky it is located.

...object in our sky? If someone had asked you this question; your answer would be the Sun. Now your answer to the question is correct but, aside from the Sun, the Moon is also the brightest and most noticeable object in our sky. The Moon is Earth’s only natural satellite. The Moon is a roughly spherical, rocky body that orbits the Earth and its diameter is about one-fourth Earth’s diameter (“Moon”). This object does more than orbits the Earth and light up the night sky. The Moon goes through a lunar phase, cause eclipses, and has a strong effect on Earth’s tides, but before the Moon could do this it had to be formed. How did our Moon form? There is a strong hypothesis suggests that it formed as the result...

...Science and Beauty by Asaac Asimov is a very good and well thought out essay. Its theses can be argued at many different levels and aspects, such as agreeing or disagreeing with the following quote: "The world is a better place because of science and technology . This particular essay can be very convincing towards agreeing with Science. The stars of space are very beautiful to stare and gaze upon. They can be even more intriguing to look at by understanding the scientific nature of these bright shinning pieces of light. Staring endlessly into the night sky can be very entertaining, but it can be even more interesting by knowing why, how or what is up there. By knowing all these scientific details it wont just be looking up at glimmers of light, rather it will be looking up at stars, galaxies, asteroids and planets, and that is a lot more interesting. The essay "Science and Beauty goes into great depth about what is in the sky. This is shown when Isaac says, "Those other bright spots, which are stars rather than planets, are actually suns. (P.312) Isaac also says, "Beyond our cluster, other galaxies and other clusters exist; some clusters made up of thousands of galaxies. (P.313) By going into this amount of depth throughout the essay, it shows and proves the thesis by knowing and seeing is a lot more interesting than just seeing. It also shows that science is not all math and formulas and that it can be very interesting and beautiful. Gazing at the stars in the...

...Between the Earth and the Sky: Viewing from Islamic Perspective The term earth had been mentioned in al-Quran for many times, in which all of them indicates that surface of includes all visible things on the surface such as land and soil, mountains, plants, trees, forests and others. Earth also defined as place which can provide the best place for human to lives on, which they can cultivate on plants and crops, create buildings and anything within limit (Neurdeng, 2010). And it is He who spread out the earth, and set thereon mountains standing firm and (flowing) rivers: and fruit of every kind He made in pairs, two and two: He draweth the night as a veil o'er the Day. Behold, verily in these things there are signs for those who consider! (Surah Ar-Rad 13:3) "He Who has, made for you the earth like a carpet spread out; has enabled you to go about therein by roads (and channels); and has sent down water from the sky." With it have We produced diverse pairs of plants each separate from the others. (Surah Taha 20:13) It is Allah Who has made for you the earth as a resting place, and the sky as a canopy, and has given you shape- and made your shapes beautiful,- and has provided for you Sustenance, of things pure and good;- such is Allah your Lord. So Glory to Allah, the Lord of the Worlds! (Surah Ghafir 40:64) Earth is basically made up of components of land, water and wind.

...The movie October Sky contains some interesting philosophical content. The movie takes place in West Virginia in the town of Coalwood in 1957. The town has a coal mine, which employs most of the men who live there. John Hickam is the foreman at the coal mine. John has two sons, and he intends for them both to work in the coal mine. One of his sons, Jim, gets a football scholarship. The other son, Homer, becomes interested in Rockets. In the movie, Homer overcomes many obstacles in order to launch rockets and get to science faire. John Hickam has a very limited world view. He thinks that the most important thing in life is working in the mine. He only seems to value people in as far as they can work in the mine. To John, any other profession is somewhat frivolous. Homer Hickam seems to be a normal teenager with normal ambitions until his world-view is turned upside-down by the sight of the Sputnik satellite streaking across the October sky. Homer decides that he wants to build and launch rockets. Logic – Homer uses logic in order to gain knowledge of rocket science, so that he can make a rocket. First, he reads science fiction comics and reads about Wernher Von Braun, who is the German rocket scientist. Then Homer meets the nerd in his school who knows about rockets. Then, Homer gets some books on science and math and teaches himself. Then Homer and his friends use trial and error to test the rockets, until they make one that launches correctly. Homer also uses the logic...

...The book of Genesis was written in a time when most knowledge was passed on by word of mouth. Science and literacy were not prevalent. God exists outside of time and space. The Genesis account of creation is God’s Word written for human understanding. The word “yom” can be interpreted as day (sunrise to sunset), twenty-four hour period or a long period of time (an age). Could God have made the universe in six twenty-four hour days? Yes, he could. However, the evidence suggests six ages. In the novel “the Martian Chronicles,” Bradbury penned a great line relating science, religion and art. “Science is no more than an investigation of a miracle we can never explain, and art is an interpretation of that miracle. Since God is beyond our understanding, I believe that God has given us scientific evidence, which supports creative design. The model presented in “The Creation Narrative” coincides with scientific theory. The Big Bang Theory states the universe was started from a void by a supernatural force and universe expanded in a great light. Genesis opens with the earth was formless and void, God (a supernatural force) said “let there light,” and there was light. The first age. Hydrogen is the most abundant element in the universe fusing with oxygen water was formed and became comets and ice. And God separated the waters and the sky. The second age. Dense regions of interstellar clouds and dust formed into stars and the residual gas and dust slowly congregated and formed planets...

The four articles are listed below with their citations in the bibliography. 1) THE PROBLEM OF SPACE JUNK – Popular Science magazine author 2) A Hot Shower Of Space Junk – by Bryan Lufkin 3) Chinese Space Junk Puts on a Fireball Show in U.S. Skies – by Alan Boyle (reporter) 4) A mysterious Russian space object could be the return of the ‘satellite killer’ – by Terrence McCoy (reporter) The Problem of space junk article is from “Popular Science” magazine with multiple authors who worked on this piece, however, the material coming from a well-known magazine is legitimate. A Hot Shower of Space Junk by Bryan Lufkin was from a magazine called “Wired” but neither magazine listed the author’s credentials. The newspapers have the following authors, Chinese Space Junk was written by Alan Boyle a reporter. And Terrance McCoy wrote the newspaper article about a Russian space object. The first two magazines do not go into great detail of their qualifications for each author, however, the newspaper do give a little more insight into this matter.

...Why is the sky blue? Have you ever wondered why our sky is blue? The molecules in our atmosphere are made up of about 78% nitrogen, 21% oxygen, .7% argon, and a small amount of trace gases. White light from our sun is made up of all the colors in the rainbow from red to violet. When the light hits our atmosphere the molecules scatter blue light more than red or green etc. so we see a blue sky! Let's do an experiment to see the effect of scattering, and some other properties of light. Get as many of the following materials as possible: A 1 liter beaker or 1 qt glass jar (a 12 oz glass will do), some milk, a laser pointer or other low power laser, a prism or diffraction grating and some lenses, and a lab notebook to record your observations. Fill the beaker with cold tap water and shine your laser through it. Mix 2-3 drops of milk into the water. Take the mixture into a dimly lit, or dark, room. Shine the laser through the side of the beaker and look through the top of the beaker, jar, or glass. What do you see? The mixture you made is called a colloidal suspension. Now shine the laser up through the side of the beaker toward the center of surface of the suspension. [Physics FAQ] - [Copyright] Original by Philip Gibbs May 1997. Why is the sky blue? A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue...

...information presented. While administering the pre-test, I told the students to do their best, but this test was not going in the grade book. This released some anxiety from the students, and they relaxed as they took the test. Some of the students were overwhelmed by the test, and continuously complained about how they didn't know about the information on the test. I reassured the students that the test was only for practice to see how much they knew about science instruments, magnets, and the planets. On the pre-test, the students performed poorly. The students were not familiar with the science instruments listed on the test. The post-test was a great success! A majority of my students passed the test with an A or B, and only a few made a C or below. I would be sure to have a blank for the planet Pluto on the test. Some students didn't like the fact that Pluto was left off the test even though we have discussed that Pluto is no longer a planet. I feel it is important to reiterate the importance of Science and how it is ever changing. When administering the test, the students took about 10 to 20 minutes to complete the test. The classroom was very quiet, and each student had a guard up around their desk so there would be no cheating. On the pre-test, out of 24 students 2 scored B's, 5 scored C's, 16 scored D's, and 1 scored an F. On the post-test, out of 24 students, 17 scored A's, 5 scored B's and 2...

...October Sky Marion Eady The film October Sky (1999), directed by Joe Johnson is based on a true story of Homer Hickman ( a coal miners son) who is inspired to build a rocket after the Russian launch of the first artificial satellite (Sputnik) into orbit. The film definitely focuses on the course theme of being a social outcast. This is explored in the film through three people, John Hickman (Homers Father), the town of Coalwood and Mr.Turner (Homers principle). Firstly, John Hickman, father of Homer Hickman and a coal miner at the Coalwood mines in West Virginia, socially outcasts his son. Why? Because John doesn’t agree with his son building a rocket. This is explored through Homers father getting in multiple fights with his son. John called Homer many hurtful words for example a minis and a thief. John never wanted to go watch Homers rocket launch, he never agreed with anything that Homer wanted to do. Homer’s father wanted him to work in a coal mine not build rockets. Homer’s father is thrilled when Homer decides to go work in the coal mine after John gets hurt at work. Homer decides to quit school, quits making rockets and go into the coal mine. After John is out of the hospital and is able to go back to work, Homers mother want him to go back to school. Homer tells him mom that he’s not going back to school and John agrees with Homer. Although John is thrilled that Homer quit building rockets, the family is finally happy and everything is good, Homer decides...

The modern view of the universe 1) What is our Sun and what is its role in the solar system? a) Our sun is a hot ball of glowing gases that is at the heart of our solar system. b) Our suns role is to give out energy and heat. This energy and heat allows for there to be life on earth. However, even though our sun is unique and life giving there are billions of stars that are just like it in the Milky Way galaxy. (Solar System Exploration, 2012) 2) What is our Milky Way galaxy and the sun’s position in it? a) The Milky Way galaxy is a spiral galaxy that has arms that extend out from the center like a pinwheel. Our galaxy is one of about 100 billion visible universes. (Solar System Exploration, 2012) b) The sun’s posistion in the galaxy is in the Orions arm of the Mily Way. However, because of how our planets are set up in our system there is life on Earth. The Sun has an almost circular orbit. The sun is just the right distance from the center of our galaxy to promote life. The planets and our sun are just the right distance apart for one of our planets, Earth, to have higher intelegance life on it. 3) What is the Big Bang and what does...
