The Debate Over Video Game Violence Essay - 1734 Words

Controversy surrounds almost every topic and has been around for centuries. Controversial topics usually involve different types of people that have two opposite points of view about a certain topic or idea. The widespread expansion of technology has allowed people all over the world to debate certain topics that they deem to have a correct understanding of. Unsurprisingly, the effect of video games on the human brain has been a controversy since video games were first released decades ago. Video games involve the use of body and mind, which causes the player to be inside of the game, and they can see the world through the eyes of the character of which they play. Some psychologists and other scientists suggest that violent video games†¦show more content†¦This controversial topic has sparked many questions in the technologically evolving world, which cannot be answered without concrete evidence from either side of the debate, but good research can point in the direction o f the side that is more correct. Over 97 percent of American teenagers play video games at an average of 13 hours per week (Greitemeyer Mà ¼gge). With so many young adults playing video games, it would make sense that some of them might already have a psychological disorder that can trigger them to be violent. However, if the a majority of the teenagers studied did not have a previous history of violence or psychiatric disorders in the study, then it might be possible to infer that video game violence and real-life violence might have a correlation. A study suggests that playing video games excessively can affect learning and behavior, but playing pro-social video games increases helping and decreases aggression (Greitemeyer Mà ¼gge). With that said, it might be difficult to differentiate people based on those who play more violent video games and those who play the pro-social games mentioned in the text. Children who play both types of games should be studied among those who pl ay specific games that fit into the violent or pro-social video game criteria, along with the control group which are the children who dont play video games at all.

Scientists Who Unlocked the Mysteries of the Universe Essay

Scientists Who Unlocked the Mysteries of the Universe Since the dawn of time, man has yearned to know the origin of existence, how life was started, and the source of creation. Many scientists, from ancient Greece to modern civilization, began the search for answers by first studying our solar system, mapping the stars, trying to unlock their secrets. These eight scientists paved the way for any basic knowledge of the universe. Born in 270 BC, the Greek astronomer Aristarchus of Samos, was the first scientist known to suggest that the earth revolves around the sun. Little is known of the childhood of Aristarchus, as well as his entire life. His only recorded works come from Archimedes and Plutarch, which discuss his ideas of†¦show more content†¦The father of modern astronomer, Nicolaus Copernicus, was born in Poland in 1743. All that is known of his childhood is that his father died when Nicolaus was ten years old, so he was raised by his uncle. Copernicus was lucky that his uncle was a prominent Bishop and made sure that Nicolaus received a good education. He enrolled in the University of Cracow to study mathematics, astronomy, astrology, and philosophy. After completing his studies there, Copernicus traveled abroad and also enrolled in the Universities of Bologna and Padua to study both medicine and law. After his return to Poland, he was elected as canon, due greatly to his uncle’s influence, so Copernicus devoted his time to astronomy. In 1512, Copernicus began a critical study of all the proposed models of the universe and decided that the model that Ptolomy was too complicated to be possible. He then created the â€Å"Copernican system†, in which the sun was the center of the universe and all the planets were in constant orbit around it. But Copernicus deemed it necessary to include two of Ptolomy’s constructions, the epicycle and the eccentric, to explain The constant variable in the movement of the planets because he believed that all planets were in a circular orbit aro und the sun. Since Copernicus used two of Ptolomy’s ideas, his model was about as inaccurate.

Western Civilization An Absolute Monarchy And It s Faults

Once the seventeenth century began, western civilization became based upon bounds. In a structured and shared-power system known as limited monarchy, rulers either became hastened within their bounds or exploded from them. As the British Isles were frustrated in the religious, political, and national voices going unheard, England developed a Protestant-run nation in conjunction with Scotland as a bounded country in 1707. Their Parliament would make their decisions, distribute the country’s wealth, and stand for the rights of individuals. The model of one man who could not be chained to a Parliamentary system was France’s King Louis XIV. His reign begins in 1643 which brings about the genuine definition of an absolute monarchy and it’s faults. Absolutism was a practice built heavily within the Middle Ages, it would include Kings as the primary shareholders of their land, partnerships with nobles and their Churches. It would prove unsatisfactory for most kingdoms a s they failed under civil war and invasion until the seventeenth century shines a new importance on superior command. Through the strife of religious reformations and international conflicts, absolutism grants those in kingship unlimited power. King Henry IV had brought France from fifteenth century centralization and the Reformation’s civil war to cleanse the people’s doubt in their King.

Analytic Commentary Drawing and Representation Essay Example For Students

Analytic Commentary: Drawing and Representation Essay Sammy is freely making marks on the blackboard he deeds little active encouragement to do It is clear from this that Sammy is acting autonomously and exercising his will in his actions. There must be a clear balance between child indicated and adult lead situations; this may vary from child to child depending on whether they are introverts or extroverts. A childs creative development requires this balance, according to Bruce (2006), in order to be fully nurtured. Sammy has a range of different colors in which to explore independently. This Will in theory enhance his self-image and provide him With a sense of control over his actions (Duffy, 1938). Drawing is important for young hillier because it is an open ended resource the boundaries for creativity are very wide ranging, this put the emphasis of mark making and creative freedom Write, 2007). The adult needs to consider the appropriateness of the different materials that are provided for Sammy, taking into consideration the aspect of physically holding the chalk shows that Sammy is developing hand to eye motor coordination (Bruce, 2006). The ideal would be a balance between familiar and new materials to work with so that Sammy is not restricted by the creativity opportunities presented to him; at the same time not intimidated by too much hospice to new materials (Duffy, 1998). This is shown by the choice to colors that Sammy has and the familiar by the blackboard being the only medium to draw on. Sammy is making aesthetic and representational choices that are intentional, he is not using instructions or stencils, This means that the marks that he is making are indicators as to what is important to him (Duffy, 1998). Prom the conversation Sammy has with the adult we find that he is representing a spider. Until the point of verifying that he has drawn a spider Gammas mind could be occupied by the many other possibilities of representation within the raring. Representation is a form of abstract thinking, it is ascribing attributes to concepts that are linked to the empirical world but require imagination in order to form meaning. This shows that drawing is similar to play because they use both everyday experience combined With imagination to form new concepts and ideas (Broached et al, 2010). Sammy uses this drawing activity to initiate conversation With the adult about his ideas and to express himself both verbally and non-verbally. (Write. 2007) states that drawing gives children the opportunity to communicate and be creative simultaneously. This in turn supports Krebs (1997) who claims that children show great flexibility in their cognitive capacity. This process of representation may happen in stages, According to Pigged (1951), drawing technique would moue from non-representational to representational. The childs first images would be random scribbles and eventually reach a stage of visual accuracy. This point View is disputed by Mathews (1994) points out that two-dimensional representation is a complex process rather than a stage. Mathews argues that drawing is context specific and Of an intentional nature to children. Early childhood practitioners should value childrens representations because they are valuable to the children themselves: however the creativity behind the drawing process is not influenced by merely acknowledging the childs accomplishments. The Creativity is developed fort aspects of the childs nature such as being open to change, flexible and innovative (Duffy, 1998). The aspect of acknowledging Sammy work promotes his ability to comprehend and explore his life experience and to bridge understating of concepts about the world around him. It is argued by Write (2007) that abstract understanding can occur form drawing; to expand on this idea and claim that art is fundamental to the human condition because it provides a medium to expression. We can assume from these points that giving young children like Sammy the opportunity to draw is a very positive step tort cultivating their developmental capacity. .ub8d00c3673adf72e8ab88d659037879c , .ub8d00c3673adf72e8ab88d659037879c .postImageUrl , .ub8d00c3673adf72e8ab88d659037879c .centered-text-area { min-height: 80px; position: relative; } .ub8d00c3673adf72e8ab88d659037879c , .ub8d00c3673adf72e8ab88d659037879c:hover , .ub8d00c3673adf72e8ab88d659037879c:visited , .ub8d00c3673adf72e8ab88d659037879c:active { border:0!important; } .ub8d00c3673adf72e8ab88d659037879c .clearfix:after { content: ""; display: table; clear: both; } .ub8d00c3673adf72e8ab88d659037879c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ub8d00c3673adf72e8ab88d659037879c:active , .ub8d00c3673adf72e8ab88d659037879c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ub8d00c3673adf72e8ab88d659037879c .centered-text-area { width: 100%; position: relative ; } .ub8d00c3673adf72e8ab88d659037879c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ub8d00c3673adf72e8ab88d659037879c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ub8d00c3673adf72e8ab88d659037879c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ub8d00c3673adf72e8ab88d659037879c:hover .ctaButton { background-color: #34495E!important; } .ub8d00c3673adf72e8ab88d659037879c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ub8d00c3673adf72e8ab88d659037879c .ub8d00c3673adf72e8ab88d659037879c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ub8d00c3673adf72e8ab88d659037879c:after { content: ""; display: block; clear: both; } READ: Commentary - Shakespeare Hamlet EssayIt is important to remember that pre-shaped activates may offer little encouragement to the creativity of children (Duffy, 1938). The role of practitioners and parents should focus on cultivating the sensitive nature of the childs choice in the imagination process and not to be too fixed on trying to develop the childs presentational skills. Focusing on trying to make Sammy a good drawer would take away from his imagination process; the adult notices this and gives Sammy the freedom to draw (Duffy, 1998). Sammy at one point Starts to use his finger to rub the chalk on the blackboard this creates a smudging effect. It is clear from the initial confined area Of smudging that Sammy is more interested in the aesthetic effect of smudging the chalk rather than to erase his drawing. He is Offered a cloth to Wipe With by the adult Who perhaps is unaware that Sammy is enjoying the physical aspect of what he is doing. Sammy answers the adults suggestion with a no; this shows him confidently asserting that it is his drawing and it is he who is in control of the imagination process. There are moments in the drawing session when Sammy is more engaged with what the adults; this is noticeable because he turns his head every few seconds towards the adults and waits for their response. Duffy (1998) argues that some form of intervention is necessary because representational drawing is when children intend to communicate and share ideas because of this some form to communication is necessary. The opposite of this is the non- interventionist approach, advocated y Duffy (1 938), this means there is no active interaction with the child. This leaves the child free form adult expectations and that may outweigh the childs own ideas and creative process. Duffy does also points out that sensitive and intuitive intervention can help the child in gaining knowledge. This analytical commentary has shown that young childrens apparently random marks have a deep meaning to them, the represent experiences and ideas. Adults; practitioners and parents, have an essential role to play in the involvement of a childs imagination; a role of ensuring creativity is not confined but enhanced (Guar and Bruce, 1932).

Lasers Argumentative Essay Example For Students

Lasers Argumentative Essay Laser stands for Light Amplification by the Stimulated Emission of Radiation. Lasers work by producing an intense beam of bright light that travels in one direction. The laser has the unique ability to produce one specific color or wavelength of light, which can be varied in its intensity and pulse duration. The newest laser systems have become remarkably precise and selective, allowing treatment results and safety levels not previously available. All lasers contain an energized substance that can increase the intensity of light that passes through it. This substance is called the amplifying medium and it can be a solid, a liquid or a gas. Einstein can be considered as the father of the laser. 80 years ago he postulated photons and stimulated emission and won the Nobel Prize for related research on the photoelectric effect. This section discusses the historical evolution from microwave lasers to optical lasers and finally to x-ray lasers and lasers discovered in space. Some theorists were on the right track, especially Planck, who proposed that nature acted by using quanta of energy. But it was the young, unknown Albert Einstein who explained everything and started the field of quantum mechanics with his paper on the photoelectric effect. Einstein showed that light does not consist of continuous waves, nor of small, hard particles. Instead, it exists as bundles of wave energy called photons. Each photon has an energy that corresponds to the frequency of the waves in the bundle. The higher the frequency (the bluer the color), the greater the energy carried by that bundle. Einsteins Nobel Prize was not awarded for either one of his relativity theories the Nobel Committee thought them too speculative at the time. Rather Einstein won the prize for explaining the photoelectric effect. Two of Einsteins 1905 papers were on the theory of atoms and molecules, yet there were still many scientists in 1905 who did not believe in atoms or molecules. There are many lasers such as the carbon dioxide laser or CO2 laser, and many forms of this too. In contrast to the old carbon dioxide lasers, the newest generation of the CO2 laser delivers short bursts of extremely high-energy laser light. In a neodymium YAG (Nd:YAG) laser, the amplifying medium is a rod of yttrium aluminum garnate (YAG) containing neodymium ions. In a dye laser, it is a solution of a fluorescent dye in a solvent such as methanol. In a helium-neon laser, it is a mixture of the gases helium and neon. In a laser diode, it is a thin layer of semiconductor material sandwiched between other semiconductor layers. The factor by which the intensity of the light is increased by the amplifying medium is known as the gain. The gain is not a constant for a particular type of medium. It depends critically upon the wavelength of the incoming light, the length of the amplifying medium and also upon the extent to which the amplifying medium has been energized. In order to increase the intensity of the light, we would need to energize the amplifying medium, or in other terms, pumping. There are several ways of pumping an amplifying medium. When the amplifying medium is a solid, pumping is usually achieved by irradiating it with intense light. This light is absorbed by atoms or ions within the medium and raises them into higher energy states. Often, the pumping light comes from xenon-filled flash tubes that are positioned alongside the amplifying medium. Passing a high voltage electric discharge through the flash tubes causes them to emit an intense flash of white light, some of which is absorbed by the amplifying medium. A laser that is pumped in this way will have a pulsed output. Pumping an amplifying medium by irradiating it with intense light is usually referred to optical pumping. In some cases, the source of the pumping light is another laser. Gaseous amplifying media have to be contained in some form of enclosure or tube and are ofte n pumped by passing an electric discharge through the medium itself. The mechanism by which this elevates atoms or molecules in the gas to higher energy states depends upon the gas that is being excited and is often complex. In many gas lasers, the end windows of the laser tube are inclined at an angle and they are referred to as brewster windows. Brewster windows are able to transmit a beam that is polarized in the plane of the diagram without losses due to reflection. Such a laser would have an output beam that is polarized. This remarkable technology is used in many fields such as surgery, military purposes, and accurate measurement in both speed and distance. Many people these days spend thousands on their low self-images by using laser surgery to enhance their looks and rid them of their blemishes. In a military point of view, lasers are a potential weapon and an extremely useful defense mechanism. Even now, sci-fi tales of the laser gun have been told, we are not far off to it s development. .u5531eb396247b28d11b9c5b7cf0468f8 , .u5531eb396247b28d11b9c5b7cf0468f8 .postImageUrl , .u5531eb396247b28d11b9c5b7cf0468f8 .centered-text-area { min-height: 80px; position: relative; } .u5531eb396247b28d11b9c5b7cf0468f8 , .u5531eb396247b28d11b9c5b7cf0468f8:hover , .u5531eb396247b28d11b9c5b7cf0468f8:visited , .u5531eb396247b28d11b9c5b7cf0468f8:active { border:0!important; } .u5531eb396247b28d11b9c5b7cf0468f8 .clearfix:after { content: ""; display: table; clear: both; } .u5531eb396247b28d11b9c5b7cf0468f8 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u5531eb396247b28d11b9c5b7cf0468f8:active , .u5531eb396247b28d11b9c5b7cf0468f8:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u5531eb396247b28d11b9c5b7cf0468f8 .centered-text-area { width: 100%; position: relative ; } .u5531eb396247b28d11b9c5b7cf0468f8 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u5531eb396247b28d11b9c5b7cf0468f8 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u5531eb396247b28d11b9c5b7cf0468f8 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u5531eb396247b28d11b9c5b7cf0468f8:hover .ctaButton { background-color: #34495E!important; } .u5531eb396247b28d11b9c5b7cf0468f8 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u5531eb396247b28d11b9c5b7cf0468f8 .u5531eb396247b28d11b9c5b7cf0468f8-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u5531eb396247b28d11b9c5b7cf0468f8:after { content: ""; display: block; clear: both; } READ: The Federalist Numbers 10/51 EssayThe laser has been used in the medical field as well. This revolutionary technology actually vaporizes the undesired skin tissue, one layer at a time, revealing fresh skin underneath. The CO2 lasers highly focused aim enables the dermatological surgeon to gently remove the skins surface with a low risk of scarring and complications in properly selected patients. The laser beam can gently vaporize and remove wrinkles, scars and blemishes, seal blood vessels or cut skin tissue. Lasers can also be used in defense. For example the use of the laser attatched onto a satellite would enable us to destroy incoming or airborne missiles before they reach their target. Even though our government wasted millions of taxpayers money on the laser defense systems, they could waste more on developing new and improved satellites, or maybe even working ones too. An alternate technique for boost-phase interception requires that space interceptors be constantly over the enemy territory. Keeping a sufficient number of interceptors continuously ready for action and over the enemy territory is costly, although not impossible. Advances in technology lasers, neutral particle beams, non-nuclear smart weapons make it possible to attack missiles as they rise. The laser is also a key tool used in measurement as well. The use of measuring with a laser is used in many fields such as measuring the distance between objects to even the speed of gases. An instrument called the iterferomete r is used to measure very small changes in distance . Todays scientist on the San Adreas fault is actually using this instrument in order to find slight movements created by the fault. Just like radar the laser can be used to measure long distances as well, but a even more accurately. Prior to the astronauts arrival on the moon, a mirror has been left in order to judge the distance between the moon and the earth by pulses of laser light aimed at the mirror. The reflection back is then divided by half, just like radar, to find the distance.
