This made Apple think of a procedure that would make their items and particularly the telephone all the more engaging. They chose to have spray painting in and on their telephones in an offer to advance craftsmanship and furthermore draw in workmanship sweethearts. This spray painting began getting so mainstream in before the end of last decade. It became famous in light of the fact that individuals could now customize their telephones in the applications through penmanship as well as on the fronts of the iPhone. Because of the way that numerous people had the iPhones, the spray painting was free to recognize people’s telephones and depict the masterful insight of a person as well as it could convey a ton about an individual just by watching the spray painting on a person’s iPhone. Vandalism as indicated by Apple is decimation of the excellence of their items for instance the iPhone. Vandalism includes utilization of terrible workmanship like awful drawings on the front of the iPhone for the sake of improving it and in the long crushes its sturdiness and even a portion of its highlights and application. Road craftsmanship then again is the spray painting done on the iPhone by individuals in the lanes. These individuals are not really approved by Apple to work for them yet they carry the spray painting from the shop to the road. Some may vandalize the item yet lion's share truly customize the iPhone dependent on the owner’s loving and tastes (Banksy 102). There are sorts of spray painting that are arranged and considered vandalism while others are viewed as craftsmanship; this is a result of numerous reasons. One reason relies upon who painted or drew the spray painting. In the event that it was done by an unpracticed and unskilled individual, at that point it is awful and considered vandalism contrasted with on the off chance that it was conveyed by an expert who might cause it to be viewed as workmanship.

The reason for this attack was not unmistakably characterized; in any case, there are several reasons that may have ascribed to Hussein's demonstrations of animosity.

The Lack Of Economical Diversity - 1186 Words

Detroit since the 1950’s has gone bankrupt and has become a place where the standards of living have dropped. Detroit a once booming city has now become an unsatisfactory place to live, due to things like extreme poverty and pollution. The main reasons for the decline are the lack of economical diversity (focused on one industry), the racial tension, the unreliable politicians, and the oil crisis. These factors all took major in roles in Detroit having to declare bankruptcy in 2013; However even after the obstacles Detroit has had to overcome, it is now back on the path to success.

Symbolism Of A Doll House By Henrik Ibsen - 937 Words

Symbolism in A Doll House In Henrik Ibsen’s A Doll House, the play is framed around symbolism and its irony. Symbolism throughout the play acts as a subliminal foreshadowing, each individually hinting at the impending end. The irony is continually represented through Ibsen’s play between perception and reality - perception being the evident meaning of each symbol and reality, being the ironic opposite connotation exclusively in Nora and Torvald’s situation. Symbolism and its ironic opposite connotation are illustrated in the first symbol - the title, A Doll House. The title suggests the ideal, picture-perfect, happy family home. In this ideal home, the expectation of each member’s role would include a hard-working, family-oriented husband and a dutiful, confidant wife. However, they aren’t much of a family at all, with little to no foundation. The â€Å"doll house† image dissolves as the underlying flaws come to light. This â€Å"doll house† image mainly lies within Nora, the doll of the play. Nora represents the doll because she is seen as no more than a decorative, bewitching plaything. Her father treated her as such and now her husband, Torvald. In the minds of her husband and father and society as a whole, she is a hollow doll, an inanimate object of beauty incapable of deep thought and lacking free will. Throughout the play, Torvald refers to Nora as his â€Å"lark† or â€Å"little squirrel†, further demonstrating his dehumanization of Nora into his personal puppet. To Torvald, Nora isShow MoreRelatedSymbolism Of A Doll House By Henrik Ibsen974 Words   |  4 PagesSymbolism In literature, symbolism is an essential tool that many writers use to enhance their stories.

Big Bang Essay Research Paper The OriginSome free essay sample

Big Bang Essay, Research Paper The Beginning Some 12 billion old ages ago the existence emerged from a hot, heavy sea of affair and energy. As the universe expanded and cooled, it spawned galaxies, stars, planets and life. Since the beginning of human civilisation, people have ever questioned the beginnings of their being and the creative activity of the existence. Cosmology, the scientific survey of the big graduated table construction and development of the existence, has developed and evolved in response to the human demand to cognize our roots ( Silk, Big Bang 1980 456 ) . We will write a custom essay sample on Big Bang Essay Research Paper The OriginSome or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Within in this field of survey, the Big Bang theory has become the most prevailing theory, because the bulk of grounds from a assortment of different probes make it highly likely that something like the Big Bang occurred. The Big Bang theory of cosmology assumes that the universe began from a remarkable province of infinite denseness. As Joseph Silk defines the Big Bang theory, it is a theoretical account of the existence in which space-time began with an initial uniqueness and later expands ( Silk, Cosmic Enigmas 56 ) . The theory foremost referenced in Alexander Friedmann # 8217 ; s complete solution of Albert Einstein # 8217 ; s equations, in 1922. In 1927, Georges Lemaitre used equations to invent a cosmogonic theory that incorporated the construct that the existence has been spread outing from an explosive minute of creative activity. However, the term # 8220 ; Big Bang, # 8221 ; as a name for the initial cataclysmal event, was chosen by two work forces named George Gamow and R.A. Alpher due to their find of background radiation, a low-temperature radiation that penetrates the existence at microwave wavelengths ( 58 ) . Its beginning is now believed to hold been the highly hot bolide with whi ch the existence began, harmonizing to the Big Bang theory. Since its initial debut, much grounds has helped to beef up its instance, and other theories have been added to it, such as the Inflationary theory. This theory seeks to account for the physical events which took topographic point in the really first minutes of creative activity. In short, the Big Bang theory is one which incorporates other theories in its effort to explicate the development of the existence. Though much grounds supports, the Big Bang theory, there are still inquiries which remain unreciprocated. Other theories that attempt to explicate the beginning of the universe exist, but the Big Bang theory has become the standard theoretical account by which others are measured. The history of the Big Bang and cosmology was born when Albert Einstein developed his General Theory of Relativity in 1915, and his first cosmogonic paper in 1917, when Einstein attempted to do the equations of relativity fit together with the wrong belief that the existence was stable and inactive, with no get downing nor an terminal ( Monsters 103 ) . Einstein # 8217 ; s theory of gravity of space-like organic structures, general relativity, has identified gravitation with the curvature of space-time, the 4-dimensional manifold that consists of the three infinite dimensions combined with clip ( Silk, Big Bang 1980 13 ) . Any event can be described in footings of its way and location in space-time. In peculiar, the visible radiation from distant galaxies logically follows the shortest possible way, called a geodesic. The mode by which one looks back in clip is by geodesics ; galaxies are about like clip machines, with the visible radiation from most distant galaxies going through s pace-time since before the Earth was even formed, 4.6 billion old ages ago. The most distant galaxies are at a distance of 10 billion light old ages, fundamentally supplying a look-back in clip of 10 billion light old ages every bit good. Einstein # 8217 ; s theory of relativity received solid verification in 1919, when the warp of visible radiation from distant stars by the Sun was measured during a entire occultation. The cosmogonic deductions of Einstein # 8217 ; s theory of relativity began to have intensive scrutiny. The thought of the Big knock and an spread outing existence which challenged Einstein # 8217 ; s thought of a inactive and unchanging existence, came chiefly from a Russian meteorologist, Alexander Friedmann, and a Belgian churchman and mathematician, Georges Lemaitre. The preparation and anticipation of a Big Bang account for the existence was singular because both work forces formulated that theory of cosmology without any steadfast experimental grounds for cosmopolitan enlargement ( Silk, Big Bang 1980 15 ) . Both work forces, in different old ages, independently discovered the solutions to Einstein # 8217 ; s equations of gravity which described an spread outing existence, flinging Einstein # 8217 ; s cosmogonic invariable and his perceptual experience of a inactive existence. Friedmann, in 1922, and Lemaitre, in 1927, demonstrated that the existence could be in a large-scale enlargement. To avoid prostration, the enlargement of the existence balanced gravitative attractive force. The enlargement could either go on everlastingly, or finally change by reversal into a stage of contraction. A principle premise of their theory was that the affair content of the existence implied that infinite was non needfully Euclidean or correspondent to the two-dimensionality of a plane in a planar analogy, but could be curved like the surface of a sphere ( with a positive curvature ) or a hyperboloid ( negative curvature ) ( Silk Cosmic Enigmas 13 ) . Since the surface of a domain is closed and finite while a hyperboloid is unfastened and infinite, it can be inferred that a existence with high affair denseness should be closed, finite, positively curved and should finally fall in, whil e a universe with low affair denseness should be unfastened, infinite, and negatively curved, spread outing indefinitely ( 14 ) . Edwin Hubble, a celebrated American uranologist of the 1920 # 8217 ; s, discovered a additive relation between distance to a distant galaxy and its red-shift in 1929 which provided exciting grounds back uping the thought of the of all time spread outing existence which came from the Friedmann-Lemaitre theoretical account. Hubble s find was influenced well by the work of a Dutch uranologist, William de Sitter, who in 1917 hypothesized that the existence possessed the curious belongings that the visible radiation from the most distant parts became increasingly reddened as the distance increased. Hubble # 8217 ; s red-shift is due to a Doppler displacement of visible radiation from a galaxy which is withdrawing. This explains that the distance of galaxies from us is linearly relative to their red-shift and hence linearly proportional to their comparative speed of recession ( Silk, Big Bang 1989 374 ) . So fundamentally, galaxies and organic structures that are twice as far from us tha n another, travel twice as fast. This thought indicates that it has taken every galaxy the same sum of clip to travel from a common point of beginning to its current place, wherever that might be. The term # 8220 ; Big Bang # 8221 ; for these theories was coined by the Russian born U.S. atomic physicist George Gamow in 1946. He was one of the strongest advocators for this theory for the creative activity of the existence, back uping the work of Einstein, Friedmann, Lemaitre, and Hubble ( Peebles 1 ) . Gamow attempted to explicate the distribution of chemical elements throughout the existence through a self-generated thermonuclear reaction. He besides proposed that in the beginning of the Big Bang, the existence consisted of a aboriginal substance called ylem. This ylem was a gas of neutrons which was at highly high temperatures transcending 10 billion grades. Because the neutrons existed in this # 8220 ; free # 8221 ; province, they began disintegrating into protons, negatrons, and neutrinos. The consequence was a boiling sea of neutrons and protons which merged together to organize heavier and heavier elements. In Gamow # 8217 ; s perceptual experience, all of the elemen ts in the full existence formed in this mode during the earliest 20 proceedingss of the Big Bang. This hypothesis, trying to account for the beginning of He and H in the existence, was submitted by Gamow and his spouse, Ralph Alpher in 1948 ( Eldredge 355 ) . Then in a follow up paper, Gamow and Alpher wrote that after the existence was created in a great ardent detonation, as the existence expanded, the radiation would non hold persisted but would hold been steadily diluted. This would explicate the necessary chilling of the existence. But the most of import portion of this 2nd paper was the anticipation of background radiation, a touchable hint to the existent Big Bang. Although in the 1940 # 8217 ; s there was no technological manner to observe such a swoon afterglow, scientists of ulterior decennaries would be able to turn out what Gamow had hypothesized ( 363 ) . As cosmology and the Big Bang theory gained acceptance by the scientific community, solid, scientific grounds was found which supported the Big Bang and Gamow # 8217 ; s theory of background radiation. In the spring of 1964, Arno Penzias and Robert Wilson, two research workers at Bell Laboratories, while mensurating noise degrees from the sky, out of the blue discovered a signal of microwave radiation which had a temperature equivalent of about 3.5 grades Kelvin ( Smoot 81 ) . The signal was coming from all waies of the sky. The account for this signal was that it was a sensing of remnant radiation from the creative activity of the existence, the Big Bang. This decision was reached because of the isotropic and black body nature of this radiation. Since isotropic means the radiation at the wavelength was every bit intense all over the seeable sky, it can be inferred that that is precisely what one should anticipate if left over radiation came from the Big Bang, that since it occurred everyplace at the same time, the afterglow should be unvarying across the celestial spheres ( 84 ) . This was a # 8220 ; smoking gun # 8221 ; giving more strength to the Big Bang theory of the creative activity of the existence and turn outing Gamow # 8217 ; s hypothesis. More late, cosmic microwaves were detected which apparently originated at the farthest, outer ranges of the existence. These microwaves were improbably unvarying, bespeaking the homogeneousness of the early phases in the creative activity of the existence. The COBE orbiter of NASA which detected these microwaves besides discovered alterations in temperature and other factors which supported old computations based upon the premises of the Big Bang theory ( Gribben 143 ) . Although, it may neer be known for certain whether the Big Bang was the definite mode of creative activity for the existence, modern scientific idea and grounds, such as that of the COBE orbiter, indicate that the Big Bang theory is at the really least, an highly plausible one. Harmonizing to the Big Bang theory, the existence began with one big detonation, which took topographic point about 15 to 20 billion old ages ago. We now refer to this detonation that began the existence as the # 8216 ; Big Bang # 8217 ; and it is from this theory that we are able to analyze the development of the existence from the msecs of creative activity to the creative activity of galaxies, and from the formation of planets to the presence of life on Earth. Because about all astronomical phenomena can be explained wholly within the context of the Big Bang, or if non wholly, can be explained to a greater grade than any other manner, this theoretical account of the existence has become the most widely accepted up to this point. However, within the model of the Big Bang theory, there are several different theoretical accounts of the existence. The standard theoretical account of the Big Bang theory takes three possibilities into consideration, displayed in Appendix A. The first 1 is the unfastened Friedmann-Lemaitre theory on the existence in which exaggeratedly curved infinite is destined to spread out everlastingly. The 2nd theory is the closed Friedmann-Lemaitre theory on the existence in which spherically curved infinite is destined to fall in once more. The 3rd one is the Einstein-de-Sitter theory which calculates that the level infinite of the existence is destined to continually spread out every bit good. Although these three theoretical accounts do non differ greatly in the initial and get downing fazes of the development of the existence, they do differ in their ulterior fazes and as one can see, they predict really different hereafters for our existence. One of the most interesting ideas which arises out of this model, is that the existence was non ever in the province which we see it presently. To analyze how the existence evolved, we must follow back through the enlargement of the existence, coming every bit near as possible to the exact minute of the Big Bang. Probably the most dumbfounding fact is that we are know in a place to depict the existence as it existed during most of the first second of being. ( Trefil 20 ) In its early phases, harmonizing the Big Bang theory, the existence was in therma cubic decimeter equilibrium. A scorching visible radiation pervaded all locations and traveled in every way, with the features and qualities of a black body at extremely high temperatures. Early on in creative activity, the temperature was in the millions of grades because it was in a extremely compressed, aboriginal province. At this highly early phase of creative activity, atoms of opposite charge freely moved about independently of one another, in a province of affair called a plasma ( Trefil 23 ) . As the infinite expanded harmonizing the Big Bang theory from a individual point of beginning, the wavelengths of visible radiation stretched out every bit good. Likewise, the enlargement of the infinite stretched the wavelengths switching the highly high temperature black body spectrum to that of a lower temperature. Blue light shifted to the ice chest ruddy light part, and the existence cooled. As the existence cooled, certain signifiers of karyon, definite sums of He, H, and Li were formed, every bit good as other signifiers of simple atoms. About 1,000,000 old ages subsequently, and about 15 billion old ages ago, the existence became cool plenty for atoms to eventually organize. Soon after the formation of atoms and the subsequent attractive force of atoms of opposite charges, another natural procedure began ( Trefil 45 ) . Under the spread outing new stuffs began to come together in bunchs. As the existence expanded, affair was being brought together in these bunchs by the force of attractive force in gravitation. Within each bunch, the gravitative forces continued to run, pulling big clouds of gases together to organize nebulae. Finally, the bunchs and clouds of gas would organize stars through a procedure known as merger. A gas cloud had small pick but to prostration and fragment into what we now know as stars. Merely the random gesture of its atoms provides a force per unit area that can defy gravitation for merely a really short clip, with atoms clashing, radiating because of the presence of heavy atoms such as C, losing their kinetic energy of gesture, and finally doing a cool down and a prostration. As the gas clouds prostration into small bunchs ; these bunchs merge together into larger, assorted fragments, and grew by accreting gas from their milieus ( Silk, Cosmic Enigmas 65 ) . This fall ining gas shortly became sufficiently dense to get down radiating energy from atomic hits, and therefore the first stars were born. Over clip many of the star bunchs dissolved because of riotous gravitative forces exerted by other clouds, and a galaxy emerged which resembled the Milky Way ( Silk, Cosmic Enigmas 69 ) . The most outstanding characteristic of this early galaxy was a rotating disc of stars and gas clouds, along with a compact cardinal spheroid form of stars which developed from those fall ining gas clouds. Five billion more old ages would travel by before one of these interstellar clouds would deliver our solar system, condensed from the leftovers of earlier stars. Finally, merely put, chemical procedures would happen to associate atoms, which were one million millions of old ages in the devising from the beginning of the existence, together to organize molecules, and so finally complicated solids and liquids, and eventually conveying us to where worlds stand now. With our ability to detect other parts, non merely the optical part, we have discovered much grounds that supports the Big Bang theory. Probably the most persuasive grounds for this theory is the presence of cosmic microwave background radiation, which can merely be detected by wireless telescopes. Cosmic microwave background radiation is diffuse isotropous radiation whose spectrum is that of a black body at 3 grades Kelvin and accordingly is most intense in the microwave part of the spectrum ( Silk, Big Bang 1989 456 ) . This radiation is thought to come from the cooled residue of the initial detonation from which the existence evolved. Because microwaves are of shorter wavelengths, merely several centimetres broad, and are therefore non in the optical window, we are non able to straight detect these. Microwave radiation besides does non normally produce heat, except at highly high strength, doing it hard to observe. However, our full existence is a great beginning of these microwav es and it was non until the production of a little wireless horn for satellite communicating, created in 1965 at Bell Laboratories in Holmdel, New Jersey that radiation was detected. The find of cosmic microwave background radiation, was important because it fit in with George Gamow # 8217 ; s theory that the elements of the existence had been created 5 proceedingss after the # 8216 ; Big Bang # 8217 ; and therefore aboriginal radiation should be scattered across the existence. He besides hypothesized that due to enlargement, the temperature of radiation should hold cooled to about 5 grades above 0. When scientists detected this radiation it became apparent that it contained a high grade of uniformity which proves its beginnings are from the farthest points of the existence ( Silk, Big Bang 1980 102 ) . Cosmic microwave background radiation has besides been found to hold about a perfect black body radiation, intending that the strength distribution of its radiation is that of a black body. Its temperature now is about 3 grades Kelvin, deducing that it is really cold. This fits in really good with the impression that the existence has been spread outing. Indeed, if the black body radiation is traced rearward in clip, it becomes hotter and hotter until it reaches the conditions to make black body radiation ; a province of perfect equilibrium between radiation and affair. Evidence is besides provided from little divergences from the black body spectrum of about 5 grades ( Monsters 4 ) . They provide of import information on the little imperfectnesss of the Big Bang, which are responsible for the construction of the existence. This find of cosmic microwave background radiation is likely the most important grounds that supports the Big Bang theory. As with many other scientific hypotheses, the Big Bang theory is non wholly infallible. Although much current grounds supports the Big Bang theory of the creative activity of the existence, there is still some degree of uncertainness environing it. In fact, there are a couple cardinal jobs associated with the Big knock. These jobs include the inquiry of: why there is so small antimatter in the existence, and what happened prior to the initial blink of an eye of creative activity? These inquiries bring up of import issues associating to the existence which have non been decently answered by the Big Bang theory. In 1932, Carl Anderson, a physicist at the California Institute of Technology, discovered a new type of atom called a antielectron, which had the same mass of an negatron, but alternatively of a negative charge, had a positive charge. This was the first illustration of antimatter to be seen in a research lab scene. ( Peebles 106 ) Antimatter fundamentally is a signifier of affair that, at the atom degree, consists of a atom whose mass is equal to that of a normal atom but carries opposite electrical charges. There are other of import belongingss of antimatter as good. Antimatter annihilates whenever it comes in contact with ordinary affair and besides can be created in energetic reactions between simple atoms. Besides, every atom has a corresponding antiparticle ( Lerner 92 ) . If we have a aggregation of atoms and certain anti-particles at a really high temperature, we would anticipate a balance to happen between these procedures of obliteration and creative activity. Every clip a brace annihilates each other, such as an negatron ( atom ) and a antielectron ( anti-particle ) , another brace would be created in a hit at a different topographic point. But as the temperature falls, creative activity can non continue any longer with obliteration since there is non adequate energy to bring forth the mass of the br ace of atoms. Then the balance dissipates and obliteration occurs until all the atoms or antiparticles are used up wholly The issue that the Big Bang theory has a difficult clip resolution is that in this atom period which scientists refer to, taking topographic point about 13 proceedingss after the Big Bang, both obliteration and creative activity of atoms involved braces, so hence, for every atom which was created or destroyed, a corresponding procedure occurred for antiparticles every bit good. But one of the interesting facts about the Earth is that there is really small antimatter at all, about none. Satellites and planetal investigations which have explored the galaxy return with the same finding of fact that there is no antimatter anyplace ( Lerner 98 ) . The inquiry is how to explicate this complete instability between affair and antimatter, non merely on Earth but besides in our galaxy. Explanations for this instability include hypotheses that before the atom epoch of the Big Bang there was already an instability between affair and antimatter, either by the existence get downing out with more affair, antimatter being segregated to another part of the existence, or a procedure happening before the atom period making matter disproportionately to antimatter. Progresss in uranology have given the most acceptance to the theory that some procedure did happen that created affair before the atom period of creative activity ( Smoot 274 ) . An interesting inquiry that comes to mind when covering with the Big Bang theory is ; if the Big Bang created the universe as we know it, so what, if anything, existed before it? A modern guess for many modern-day scientists and physicists is that the present enlargement may be one rhythm of many which this closed existence has undergone. But in world, it is impossible to cognize what could hold existed or occurred before the Big Bang scientifically. We can merely theorize philosophically about what could perchance hold been before the initial minute of creative activity. It is singular that although modern scientific discipline can find what occurred one minute after the large knock, that it is impossible to find what existed or occurred before. We face the chance of neer cognizing the reply to this and other related inquiries sing creative activity of the existence. One can see that the Big Bang theory of creative activity is by no agencies an airtight, wholly unafraid theory. Questions such as that of the formation of galaxies, and antimatter can be hypothesized about but neer wholly explained. Problems with this widely accepted theory do be as one can see, but the famine of grounds may bespeak that the Big Bang theory is more accurate than non. Although the Big Bang theory does non yet explicate everything about the development of the existence, it does so explicate an ample sum. With the progresss in modern engineering, much convincing grounds has been discovered adding farther credibleness to this model of the existence. The Big Bang theory makes development and alter the cardinal construct of its cosmology. As uranologists and physicists gain more information from more proficient instruments such as the COBE infinite orbiter and the Hubble Space Craft, they will doubtless detect more elements of the existence that will lend to our apprehension of its development. # 8220 ; Smaller # 8221 ; inquiries such as the deficiency of antimatter, the universe position before creative activity, and the possibilities of cosmopolitan contraction still puzzle scientists. However, the biggest inquiry that they have yet to find is whether the existence will spread out indefinitely or will finally fall in upon itself and possibly reiter ate the procedure, everlastingly.

Ultimate Recreational Vehicle Essays - Coastal Geography, Dune

Ultimate Recreational Vehicle The Ultimate Recreational Sport Michael Lackie For as long as I can remember, my family has always enjoyed recreational sports. In the summer we would go jet skiing, river rafting, off road motorcycle riding, and water skiing. Once winter came along, we switched to snowmobiling, snowboarding, and hunting. My father and his brother owned all the expensive toys, while my brothers, cousins and I owned the cheaper toys. While it was fun using our parents expensive toys, we had to be careful not to damage them. So for years we saved our money in the hopes of buying our own expensive toys, but we could only save enough for one; therefore, we needed to find one that would fit all of our needs. I explained the problem to a friend, who then proceeded to tell me about this ultimate recreational sport that should solve my problem. I was to meet my friend in the morning to help him pack up for the ultimate recreational sport that would solve my dilemma. I arrived at his house early the next morning and helped load up the all terrain vehicles that we would be riding. They were motorcycles with four wheels instead of two and looked like an oversized tricycle with big paddle tires on the front and rear. These particular models were called Yamaha Banshees. We loaded up three of them on a trailer attached to the back of his truck, then drove for a couple of hours before finally reaching our destination. I woke up to see miles and miles of sand dunes, and noticed we were on the border of Mexico and California in a place called Glamis. I thought this was going to be an interesting experience even if I did not like it. After unloading the Banshees, we suited up with protective gear and helmets. My friend led the pack and there were about ten riders in all. I stayed back as this was my first time riding on the sand dunes. Everybody took off at full speed and there was sand flying everywhere, so I had to stay out of the way or else eat lots of sand. Once I learned how to ride without getting sand in my face, then I started to catch up with the group. From that moment on, I knew this was going to be fun. We rode up and down sand dunes jumping off them and riding on top of them for hours before we finally stopped for a rest break at the top of a real high dune. Sitting there, we could see nothing but sand dunes for miles and I wasn't sure which way was back to camp. Then my friend pulled out a global tracking system and it showed exactly where we were located, so this set my mind at ease. Although it was just sand dunes, there was something calming and beautiful about them, and I fell in love with them from that point on. Once we caught our breath, we continued the journey deeper into the dunes. We rode on dunes that were over one hundred feet high and could reach speeds of up to eighty miles an hour around the edges. Then we came across dunes that were so high and steep that we almost couldn't make it to the top without considerable effort. Once nightfall came, and the moon came out, it was even more fun riding because the moon reflected off the sand and lit up the night. We eventually arrived back at camp and settled down for the night, exhausted but satisfied. I was convinced that I had found the one vehicle that we could purchase and fit all of our needs. Riding the Banshees in the sand dunes was like snowboarding, water skiing, motorcycling, and river rafting all combined into one sport. I went back home happy in my quest that I had found the ultimate recreational sport. Bibliography Personal Experience Sports and Games Essays
