Rubber Band Powered Vehicle Essay - 1132 Words

Rubber Band Powered Vehicle Part A: Introduction a. Theoretical Background The rubber band car is a car powered by a single rubber band. Energy efficiency is the amount of energy that is first stored in an object. The physics definition of energy efficiency is very similar. Their term is the linear distance traveled using the energy stored in one rubber band. Energy efficiency is usually found when an objects energy transfers into a different type of energy. For us to find this, we have to attach a rubber band onto the car and release the rubber band to make the car move forward. The physics definition is very reasonable because the rubber is the main and only source of energy that is applied to the car. b. Purpose The purpose†¦show more content†¦20.

Graph Part G: Conclusion We found that our rubber band car is very energy efficient. After building our rubber band car, we have tested it 10 times. The average result of all 10 of these trial is that the car travels up to 9 meters within a little under three seconds. Our hypothesis was correct since the car traveled in a linear motion. The rubber band that is connected to the axle of the car is released, making the rear wheels rotate and allowing the car to move forward. We find that teamwork was a very important key to our success.

History Of Photography Essay Example For Students

History Of Photography Essay Towards the end of the century there was a growing dissatisfaction with the photographic establishment in England and in America. At the turn of the century Stieglitz was the most important photographer in America. In England this led to a mass of resignations from the Photographic Society, and the formation of a group known as the Linked Ring, whilst in America, in 1902, an avant-garde group of photographers led by Stieglitz, also sought to break away from the orthodox approach to photography, and from what they considered was the stale work of fellow photographers. At the beginning of the twentieth century, Stieglitz had already engaged in his long fight to have photography recognized as a valid medium of artistic expression. The American group came to be known as the Photo-Secession, the name Secession coming from groups of artists in Austria and Germany who had broken away from the academic establishment. Composed of carefully selected pictorial photographers, the society often did the best and most original photography produced in the United States and abroad. Their rejection of establishment photography was aptly summarised in Photograms of the year for 1900: That wealth of trivial detail which was admired in photographys early days and which is still loved by the great general public. has gone out of fashion with advanced workers on both sides of the Atlantic. The Photo-Secession Gallery, better known as 291 at 291 Fifth Avenue in New York, was devoted to these photographers and their aesthetic. The gallery was not limited to photographers, but also to painters who were finding new modes of expression, such as Picasso, Matisse, Maurer, and Freuh. Many critics held the opinion that 291 was the only focal point of Modern Art in America until the Armory show in 1913. It was in these gallery rooms that the ice was broken for modern art in America. Composition, massing of light and shadow, arrangement of lines, development of curves, were the means. With them they sought values, textures, character, any aspect which would appeal to the emotions of the viewer. Characteristic of the photography of this new movement was the employment of special printing processes for example gum bichromate, and of artwork which lessened the detail on the finished print. The movement was not without its critics. Sadakihi Hartmann reacted strongly to the idea of manipulating photographs, and decried those who strove hard to make their pictures seem as if they were not photographs at all. In American AmateurPhotographer 1904 he wrote: We expect an etching to look like an etching, and a lithograph to look like a lithograph, why should not then a photographic print look like a photographic print? It was not that he objected to retouching or dodging: And what do I call straight photography, one might say, can you define it? Well, thats easy enough. Rely on your camera, on your eye, on your good taste and your knowledge of composition, consider every fluctuation of color, light and shade, study lines and values  and space division, patiently wait until the scene or object of your pictured vision reveals itself in its supremest moment of beauty, in short, compose the picture which you intend to take so well that the negative will be absolutely perfect and in need of no manipulation.

Untitled Essay, Research Paper Anselm # 8217 ; s Ontological Argument and the Philosophers Saint Anselm of Aosta, Bec, and Canterbury, possibly during a minute of enlightenment or starvation-induced hallucination, succeeded in explicating an statement for God # 8217 ; s being which has been debated for about a thousand old ages. It shows no mark of traveling off shortly. It is an statement based entirely on ground, separating it from other statements for the being of God such as cosmogonic or teleological statements. These latter statements severally depend on the universe # 8217 ; s causes or design, and therefore may weaken as new scientific progresss are made ( such as Darwin # 8217 ; s theory of development ) . We can be certain that no such destiny will go on to Anselm # 8217 ; s Ontological Argument ( the name, by the manner, coined by Kant ) . In signifier, Anselm # 8217 ; s statements are much like the statements we see in doctrine today. In Cur Deus Homo we read Anselm # 8217 ; s conversation with a skeptic. We will write a custom essay sample on Untitled Essay Research Paper Anselm or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This kind of question-and-answer signifier of debate ( dialectic ) is really much like the Hagiographas of Plato. The skeptic, Boso, inquiry # 8217 ; s Anselm # 8217 ; s religion with an array of inquiries non-believers still inquire today. Anselm replies in a bit-by-bit mode, inquiring for verification along the manner, until he arrives at a decision with which Boso is forced to hold. This is merely like Socrates # 8217 ; process with, say, Crito. Subsequently philosophers have both accepted and denied the cogency of Anselm # 8217 ; s celebrated ontological statement for the being of God, presented in both the Proslogium and Monologium. Anselm did non first attack the statement with an unfastened head, so analyze its constituents with a critical oculus to see which side was best. Anselm had made up his head about the issue long before he began to utilize dialectic to try to dissect it. Indeed, the extreme ardour which impels him to seek everyplace for statements favourable to the tenet, is a confession his portion that the tenet demands support, that it is problematic, that it lacks self-evidence, the standard of truth. ( Weber, V ) In chapters 2-4 of his Proslogium, Anselm summarizes the statement. A sap is one who denies the being of God. But even that sap understands the definition of God, a being than which nil greater can be conceived. But the sap says that this definition exists merely in his head, and non in world. But, Anselm observes, a being which exists in both world and in the understanding would be greater than one that simply exists merely in the apprehension. So the definition of God, one that points to a being than which nil greater can be conceived , points toward a being which exists both in world and in the apprehension. It would be impossible to keep the construct of God in this mode, and yet deny that He exists in world. The statement was criticized by one of Anselm # 8217 ; s coevalss, a monastic named Gaunilo, who said, that by Anselm # 8217 ; s logical thinking, one could conceive of a certain island, more perfect than any other island. If this island can be in the head, so harmonizing to Anselm, it would needfully exist in world, for a # 8216 ; perfect # 8217 ; island would hold this quality. But this is evidently false ; we can non do things exist simply by conceive ofing them. Anselm replied, continuing his statement ( in many, many words ) by stating that they are comparing apples and oranges. An island is something that can be thought of non to be, whereas the non-existence of that than which a greater can non be conceived is impossible. ( Reply, ch.. 3 ) Merely for God is it impossible non to be ; mere islands or other things do non suit this quality. Copleston amounts it up compactly ( for Anselm doesn # 8217 ; t ) : it would be absurd to talk of a simply possible necessary being ( it is a contradiction in footings ) , whereas there is no contradiction in speech production of simply possible beautiful islands. St. Thomas Aquinas rejects the statement, stating that the human head can non perchance conceive of the thought of God by ground entirely ( a-priori ) , as Anselm might. The statement does non do sense by itself, and must first supply an thought of the being of God with an analysis of God # 8217 ; s effects ( a-posteriori ) , to which Thomas turns. I think there is grounds in Anselm # 8217 ; s Hagiographas that he would differ, stating that the thought of God is an unconditioned one given to us by God, and demands no other disclosure to convey it approximately. Hence, this being, through its greater similitude, assists the look intoing head in the attack to supreme Truth ; and through its more first-class created kernel, teaches the more right what sentiment the head itself ought to organize sing the Creator. ( Monologium, ch. 66 ) Although St. Thomas was evidently a truster, he was non swayed by the thought of ground entirely being sufficient to turn out God # 8217 ; s being. His expostulation of the human head # 8217 ; s capableness to ascertain God is echoed by other philosophers such as Kierkegaard ( who was besides a Christian ) : The self-contradictory passion of the Reason therefore comes repeatedly into hit with the Unknown # 8230 ; and can non progress beyond this point. [ Of God: ] How make I cognize? I can non cognize it, for in order to cognize it, I would hold to cognize the God, and the nature of the difference between God and adult male ; and this I can non cognize, because the Reason has reduced it to compare with that from which it was unlike. ( Kierkegaard, 57 ) Anselm disagrees, and explains why light of God through rational discourse brings Man closer to God. So, doubtless, a greater cognition of the originative Being is attained, the more about the animal through which the probe is made attacks that Bing. ( Monologium, ch. 66 ) Descartes restates Anselm # 8217 ; s statement for his ain intents, which include specifying what kinds of cognition is around that is grounded in certainty. Most ulterior philosophers tend to utilize Decartes # 8217 ; preparation of the statement in their analyses. Required for Descartes # 8217 ; undertaking is God, who granted worlds the concluding capableness with which we can cognate truths. The signifier of Anselm # 8217 ; s statement he uses involves specifying # 8216 ; being # 8217 ; as one of God # 8217 ; s many flawlessnesss. Being is a portion of T he construct of a perfect being ; anyone who denied that a perfect being had the belongings being would be like person who denied that a trigon had the belongings three-sidedness # 8230 ; the head can non gestate of triangularity without besides gestating of three-sidedness # 8230 ; the head can non conceive of flawlessness without besides gestating of being. ( Fifth Meditation ) Several philosophers ask what belongingss needfully should be ascribed to God, and if being is one of them. Lotze asks how a being # 8217 ; s existent being logically follows from its perfectness. This tax write-off, Lotze says, satisfies our sentimental values that our ideals must be. Why should this thought [ a perfect being s unreality ] disturb us? Obviously for this ground, that it is an immediate certainty that what is greatest, most beautiful, most worthy, is non a mere idea, but must be a world, because it would be unbearable to believe [ otherwise ] . If what is greatest did non be, so what is the greatest would non be, and it is non impossible that that which is greatest of all imaginable things should non be. ( Lotze, 669 ) The head can plan fantastic and antic things. Where is the false belief in thought of a perfect, unreal something? Descartes # 8217 ; preparation which ascribes # 8216 ; being # 8217 ; to a most perfect being leads us to the most celebrated expostulation to Anselm # 8217 ; s statement, from Kant. Kant has a job with handling # 8216 ; being # 8217 ; as a belongings of a thing, that it makes no sense to speak of things which have the belongings of being and others which do. See the plausible state of affairs of inquiring my roomie Matthew to acquire me a beer. What sort of beer? he replies. Oh, Budweiser. And a cold one, at that. Besides an bing one, if you # 8217 ; ve got any, I might stipulate. Something merely seems awry. For Kant, when you take off # 8216 ; being # 8217 ; from a construct of a thing, there is nil left to trade with. It makes no sense to speak of an omniscient, almighty, all-good God, nor of a red-and- white, cold, non-existent Budweiser. A thing either exists, with belongingss, or it doesn # 8217 ; t. Where Descartes and Anselm would state you are doing a logical contradiction by stating God does non exist because of the fact that this statement conflicts with the really construct of God including the belongings of being, with Kant, doing this kind of a statement involves no contradiction. For contending non-existence as a portion of a thing # 8217 ; s concept kind of negates any argumentative power that the construct # 8217 ; s other qualities might hold had. A construct of a thing should concentrate on its specifying qualities, such as cold and Budweiser, instead than on its being. Anselm # 8217 ; s original answer to Gaulino might be applicable here in a defence against Kant. Possibly it is possible to deny the being of mere things ( be they islands or Budweisers ) without logical contradiction, but in the instance of a most-perfect being, # 8216 ; being # 8217 ; must be portion of its construct. Possibly it is possible that an island can be said non to hold existed, possibly if tectonic home bases hadn # 8217 ; T shifted in a certain manner. But God is non bound by the restraints of causality ; God transcends cause, bing throughout all clip. So in the construct of God is # 8216 ; being # 8217 ; , every bit good as His assorted other properties. So to state God does non be is contradictory, after all. Kant counters this with a lay waste toing blow. He reduces the ontological statement to a tautology: The construct of an all-perfect being includes being. We hold this construct in our heads, hence the being must be. Therefore, an existent being exists. Even if we grant the statement legion favours, allowing it flight from plentifulness of idiosyncrasies, in the terminal, it still doesn # 8217 ; t truly state us anything uncovering. All the problem and labor bestowed on the celebrated ontological or Cartesian cogent evidence of the being of a supreme Being from constructs entirely is problem and labor wasted. A adult male might every bit good anticipate to go richer in cognition by the assistance of mere thoughts as a merchandiser to increase his wealth by adding some zeros to his cash-account. ( Kant, 630 ) Anselm # 8217 ; s statement was non designed to convert disbelievers, but to be nutrient for trusters like Gaunilo who wished see what consequences the tool of dialectic will convey if applied to the inquiry of God. While today the statement seems weak, or even capricious, it is a courageous effort to travel without tenet in explicating God. The statement must stand or fall by its sheer dialectical force. A principal ground of our trouble in appreciating its power may good be that pure dialectic makes but a weak entreaty to our heads. ( Knowles, 106 ) I think I stand with St. Thomas and Kierkegaard in this affair, for it seems that a strictly logical statement of God # 8217 ; s being is slightly out of topographic point. One must be in a place of religion seeking apprehension , in an a-posteriori province of head to appreciate an a-priori cogent evidence such as this. This is slightly uneven and unsettling, for I tend to hold with logically sound statements at all other intersections of my life. It seems as if Church tenet these yearss accentuates the enigma of God, remaining off from concluding such as Anselm # 8217 ; s to pull followings. For to hold faith in the enigma is what is admirable. One should non be tempted to go to church smugly because it is unlogical non to. Anselm.
