Unfortunately, we can not reserve fossil fuels, such as coal and oil forever, though what we can do is introduce another power source for the likes of vehicles, whether this is a slowly but surely start, any positive impact on our fuel consumption as a whole and reduction of global warming. There is a vital need of this information to be distributed to individuals around the world, as whether it is our generation which faces the issue of green house gas emissions or the future generation, one way or another we have to deal with it. The idea is to make the world realise that term ââ¬Ëhybridââ¬â¢ is feasible and available to everyday consumers, of course at a price, but what isnââ¬â¢t? I will extract data from various research and development programs and compare it to the current hybridââ¬â¢s which are available and observe the room for improvement. The contribution that will be put in has its limits, as I can not produce a new alternative or redevelop a current form, though it is my duty to identify and produce evidence of the type of hybrid and power units that can modernise todayââ¬â¢s world effectively, safely and most importantly cleanly. I will determine how the new generation of hybrid cars, which uses a combination of two or more distinctive power units to move a vehicle. This will include the comparison with conventional power units, such as petrol and diesel engines. A thorough analysis will also be carried out, along with advantages and disadvantages, in relation to efficiency, resources, safety, performance emissions and other deriving factors. Hybrid vehicles are deemed to be the future for vehicle transportation, as fossil fuels are diminishing, whilst pollution is greater than ever. Technically, this is a resultant substitute for the conventional power source, though does this ultimately ridden the problem? If this is the case, would it a short or long term change? 1.2à Methodology I will extract information from various sources, including textbooks, internet and applying my common sense and literature towards it. I will firstly research in depth on the subject, and then followed by planning and structuring the report. I will use comparative arguments in order to review hybrid cars and other fuel types. 2 Hybrid Vehicle 2.1 History Since the early 1900ââ¬â¢s, car designers have been experimenting with electric and hybrid power units. Hybrid vehicles were produced beginning as early as 1899 by Lohner-Porsche, who is best known for creating the first hybrid vehicle (gasoline-electric), the Volkswagen Beetle, the Mercedes-Benz SS/SSK, as well as the first of many Porsche cars. Early hybrids could be charged from an external source before operation; hence the term plug-in hybrid has come to mean a hybrid vehicle that can be charged from a standard electrical wall socket. While employed at Lohner Coach Factory, Ferdinand Porsche developed the Mixte; a 4WD series-hybrid version of System Lohner-Porsche electric carriage previously appeared in 1900 Paris World Fair. The Mixte included a pair of generators driven by 2.5-hp Daimler IC engines to extend operating range and it could travel nearly 40 miles on battery alone and it was presented in the Paris Auto Show in 1901. The Mixte broke several Austrian speed record s, and also won the Exelberg Rally in 1901 with Porsche himself driving. The Mixte used a gasoline engine powering a generator, which in turn powered electric hub motors, with a small battery pack for reliability. It had a top speed of 50à km/h and a power of 5.22à kW for 20 minutes. As a result of this, the internal combustion had reformed as the ââ¬Ëbestââ¬â¢ at the given time and inheriting the power source for automobiles for over a century. Between this time, petrol and diesel powered vehicles took the opportunity to boost their technological advancements, which included fuel injection and computer controlled systems that aided the fuel efficiency, safety and power. 2.2 How it functions As we know, a conventional car has a fuel tank, along with an internal combustion engine and a transmission, which ultimately work simultaneously to turn the wheels of the car, thus making movement. In saying so, the fuel tank allocates fuel, such as petrol or diesel to the engine and therefore, the engine processes the fuel through the transmission, causing the wheels to turn. Like all batteries, hybrid batteries have two electrodes (which collect or emit an electric charge) that sit in an ion-rich solution called the electrolyte. (An ion, by the way, is an atom or group of atoms with an electrical charge.) The electrodes are typically very close, so a polymer film, called a separator, prevents them from touching, which would create a short circuit. An on-off switch in whatever device is powered by the battery- your phone or laptop- bridges the cellââ¬â¢s electrodes to generate power. Thatââ¬â¢s when the electrochemical reaction begins. Keep in mind: What we commonly call ââ¬Å"a batteryâ⬠is actually a battery pack that houses many individual cells. Your mobile phone battery is just one single cell, but anything larger- even a laptop battery- uses multiple cells working together. Ionized elements in one electrode are in a chemical state where they are easily attracted to combine with other molecules, emitting electrons (energy) in the process. Those elements are tugged through the electrolyte and the separator toward the opposing electrode. The ions of the negative electrode (anode) give up electrons; the positive ions coming toward the anode accept them. The electrons released during this process travel through the external circuit (e.g. your phone), producing a flow of charge in the opposite direction to the flow of ions. During recharge, current is forced into the cell, reversing the process. As we take a tour of hybrid batteries, remember one thing: Total energy determines the vehicleââ¬â¢s electric range, whereas available power determines its acceleration.à (hybridcars.com/hybrid-car-batteryà ) On the other hand, a hybrid vehicle consists of two parts, the internal combustion engine and the electric motor to form motion on the vehicle. Furthermore, the means of this is so that depending on the environment the vehicle is driving in, it will switch between the fuel engine and the electric motor, in order to maximise efficiency. Examples of this would be whether the vehicle was driving through urban or rural roads or even dependant on speed. This particular combination is called HEV (Hybrid Electric Vehicle) and is also important to note that is predominately used with diesel as the fuel 2.3à Types of hybrids There are many types of hybrids and whilst some are quite similar to each other, in terms of functionality, they are in fact two diverse designs. However, they are both built around improving fuel mileage and better the emissions to limit the harm to the environment. The Mild hybrid focuses more on the traditional fuel engine, whilst integrating the three major components. It is conveyed around the assistance of the electric motorââ¬â¢s function for the fuel engine. In the case of conventional vehicles, motion of the force is what makes it a fuel engine. In addition to this, the electric power only comes into the picture when further power is needed. Due to the fact that the vehicle is only using energy where essential, it is increasing fuel mileage. This design has enabled the electric motor to do more than one task, which is either charge the vehicles battery or use vital electricity to help boost the performance of the vehicle. Unfortunately, the design has limited the possibility of doing both tasks simultaneously. Honda is a prime example of Mild hybrid systems, developed in models such as the Civic and Insight. On the other hand, Full hybrid vehicles are designed differently, but the three key components are well and truly there. However, this is deemed to be more complex, in terms of benefiting the vehicle. The Full hybrid is able to utilise its electric motor independently under certain conditions of the fuel engine. The electric motor will take over, depending on certain models, which means if the vehicle is moving at a constant lower speed and will only have use of the fuel engine when acceleration is required. Though, if the fuel engine permits it, they can both work simultaneously. Periods of high speed, like in the case of highway passing is an example of the two engines working together. Full hybrid cars are capable of both charging and using energy from the battery at the same time. Ultimately, whether the vehicle is mid or full hybrid, they are both economically friendly, reducing emissions, whilst increasing whole life cost to include cost of manufacture. 2.4à Technology You can argue that, although the HEV is combined, the battery or electrical motor would still need to run on chargeable cells, thus being expensive. However, the defining feature the HEV has is its RESS (Rechargeable Energy Storage System), which productively allows the system to be recharged, from the actual process of operating the vehicle and does not need any form of ââ¬Ëplugging inââ¬â¢. For example, the regenerative breaking converts the vehicles kinetic energy into energy, which is stored by the battery or capacitors. Hydrogen Fuel Cells: Hydrogen fuel cells consist of: Anode Membrane Cathode Electro engine Power electronics Batteries Hydrogen tank A fuel cell is a combination of electrodes sandwiched around an electrolyte. Oxygen passes over one electrode and hydrogen over the other, generating electricity, water and heat. There are two main hurdles that stand in the way of mass production and widespread consumer adoption of hydrogen fuel cells. One is the high cost of producing fuel cells, which cost $1million to produce one vehicle and Toyota and Honda are currently leasing to Japan and California. It is important to note that, although it seems very expensive to produce a vehicle right now, Toyota is hoping to reduce this cost to $50,000 by 2015. I believe that the current cost would not make a make a difference to society, as the same with the current hybrid of electric vehicles. The reason for this is because everything is in production and to be quite honest, the world is not ready for a huge step, especially when the acceptance of hybrid vehicles as a whole is still in acceptance and surge of demand still waits. The second issue, which of course is in relation to the first, typically consists of the lack of hydrogen refuelling stations. As we all know, it is safe to say that majority of vehicles on the road are under the influence of petrol or diesel applied engines. Therefore, oil companies may be reluctant to push the idea of hydrogen fuel, when they are perfectly indulging in their most profitable sector ââ¬â petrol and diesel. And why not though? It is fairly logical to stand by your current business affairs when they are keeping yourself and shareholders happy. Though to be fair, Shell and BP have been promoting this idea and working with a dealership, which I will elaborate further down. There are many factors involved in which understandably fright oil companies, such as safety, cost and of course, lack of demand. However, one company which has an extremely good reputation with hydrogen being their middle name and this is the ââ¬ËCalifornia Fuel Cell Partnershipââ¬â¢. They are a non-profit based company, who admire the concept of ending petroleum dependence and making a positive change to society. We can question whether this direction is possible or whether consumers will ultimately accept it, but without research and attempting to better the need for zero emissions as a whole, we will never know, right? As of now, we do not know any better, we isolate ourselves with the nature of life, believing that life today, will consist of the same resources in 50-100 yearsââ¬â¢ time ââ¬â or do we know the truth about commodities and turn a blind eye to limited resources and let the future generation deal with it ââ¬â perhaps. The California Fuel Cell Partnership is a public-private partnership to promote hydrogen vehicles (including cars and buses) in California. It is notable as one of the first initiatives for that purpose undertaken in the United States. In January 1999, two state government agencies- California Air Resources Board and California Energy Commission joined with six private sector companies- Ballard Power Systems, DaimlerChrysler, Ford Motor Company, BP, Shell Hydrogen and ChevronTexaco- to form the California Fuel Cell Partnership. The goal was to demonstrate and promote the potential for fuel cell vehicles as a clean, safe, and practical alternative to vehicles powered by internal combustion engines. Within a very short time, other government agencies and private businesses became members. In November 2000, the West Sacramento headquarters opened. The building includes a public gallery, offices, hydrogen fuelling station and indoor service bays for vehicle maintenance. At first, the automakers had just handful of cars all stationed in Sacramento. The goal was to see if these vehicles and fuel could be technically viable. If the answer was no, then CaFCP would close its doors in 2004. Before the first phase was finished, CaFCP members knew that the technology could succeed. The number of members grew to 33 and set a new set of goals for the next phase of operation, from 2004-2007. During this period, CaFCP members worked on project to prove or disprove the commercially viability- would the vehicles, fuels and public policies meet consumer expectations? In mid-2006, the members agreed that FCVs could be a commercial success. They agreed to a third phase through the end of 2012 to lay the foundations for a commercial market, which includes developing early retail stations, policies to enable the sale of retail hydrogen and necessary steps to building a supplier base for large-scale production in the future. CaFCP completed its first phase of operation in December, 2003. The second phase will conclude in December, 2007. In mid-2006, the members agreed to enter a third phase to encourage fuel cell vehicle commercialization that will continue through 2012. The California Fuel Cell Partnership is a unique collaborative of auto manufacturers, energy companies, fuel cell technology companies and government agencies. The members collaborate on activities that advance the technology, such as first responder training, community outreach and agreeing on protocols while standards are being developed. Automotive members provide fuel cell passenger vehicles that are placed in demonstration programs, where they are tested in real-world driving conditions. Energy members work to build hydrogen stations within an infrastructure that is safe, convenient and fits into the community. Fuel cell technology members provide fuel cells for passenger vehicles and transit buses. Government members lay the groundwork for demonstration programs by facilitating steps to creating a hydrogen fuelling infrastructure. What is the difference between a fuel cell and a battery? Fuel cells and batteries are similar because they use a chemical reaction to provide electricity. A battery stores the chemical reactants, usually metal compounds like lithium, zinc or manganese. Once used up, you must recharge or throw away the battery. On the other hand, a fuel cell actually creates electricity through reactants (hydrogen and oxygen) stored externally. The fuel cell will produce electricity as long as it has a fuel supply. In short, a fuel cell vehicle is refuelled instead of recharged. Why is it taking so long? Well, this is a question everyone wants to know the answer to, I mean if there, why not release it? The problem is, technology, especially being new takes many years to come to the market. Before selling anything, it is important to create and enforce regulations and standards, to ensure that consumers get what the pay for. The California Fuel Cell Partnership is a prime example of their members working together on the barriers which front us all and by doing so, they can streamline a process from years to months. Is hydrogen a safe fuel? The term ââ¬Ëfuelââ¬â¢ is not to be taken lightly and when dealing with any type of fuel, it is important to handle with care, just as hydrogen is done. For more than 50 years, hydrogen has been produced and used for commercial and industrial purposes with an exemplary safety record. Like all fuels, hydrogen has high energy content and must be handled with care. CaFCPââ¬â¢s members are building fuel cell vehicles and fuelling stations that meet or exceed safety standards. In addition, our members are defining new safety measures. Like gasoline and other fuels, hydrogen is flammable. Unlike conventional fuels, it is very buoyant. With proper ventilation, hydrogen dissipates rapidly into the air, greatly reducing the chance of fire. Hydrogen is non-toxic, so if released it does not present a health hazard to humans and its effect on the environment is benign. Petroleum Dependency and Fuel Cell Vehicleââ¬â¢s Vehicles in the U.S. consume twice as much oil as the country produces. The number of vehicles on the road and the number of miles they drive increases every year, but U.S. oil production capacity remains about the same. In 2008, nation (U.S) consumed about 213,810 gallons of gasoline daily- 78 million barrels of oil in just one year. (A barrel is 42 U.S gallons.) The National Research Council projects that by 2050 they will consume about 1.5 billion gallons of gasoline a year, assuming that most of the vehicles on the road are highly efficient conventional, hybrid and flex fuel vehicles. If most of the vehicles are fuel cell and battery electric vehicles, gasoline consumption decreases by almost 70% to less than 50 million gallons a year- roughly half the current domestic oil production. 3 Current Issues with Conventional Vehicles 3.1à Fuel Capacity Fuel consumption and fossil fuels as a whole are again, diminishing is one of the reasons why hybrid vehicles and other power units are an opportunity cost.à On top of this, the annual fuel cost is increasing for conventional cars, whether it is petrol or diesel. Due to the environment we live in, it is impossible to rely on the fossil fuel itself to increase Miles Per Gallon, instead the only option is to render the current technology of the vehicle. Nevertheless, there are myths out there which try to better than conventional car with the likes of driving economically or using premium petrol, but how real are these myths? Well according to Susan Winlaw, co-author of the book, Car Advice for Women (and Smart Men says, ââ¬Å"Unless you have a job that requires regular sessions on a racetrack, there is no legitimate need to ever put premium fuel in your vehicle. Using regular gas could cost you a few horsepower when youââ¬â¢re driving at higher speeds, but chances are you wonââ¬â¢t notice the difference, and it definitely wonââ¬â¢t hurt your car. Your engineââ¬â¢s fuel-management system is perfectly prepared to handle lower-octane fuelâ⬠says Winlaw. (Source:http://moneywatch.bnet.com/economic-news/article/6-myths-about-gas-mileage/317188/). Well, this is down to personal experience and most importantly, trial and error, unless this is a fact, as the norm would be, most individuals would not want pay the higher price to observe savings, when fuel prices are costly in the first place. So how do we be more economical? Do we drive with our air conditioning off or do we drive the road speed limit? In my experience, I was never fond of speed cameras being put left, right and centre and the daring part of being on the lookout for those cars with the flashing lights. Though I have to say, driving according to the road speed limit actually increased my MPG from A to B, which thoroughly surprised me to say that I do favour speed cameras and speed limits. In relation to this, it has been stated in reality ââ¬Ëfuel efficiency doesnââ¬â¢t really start to drop until you reach speeds higher than 60. And how smoothly you drive makes much more of a difference on petrol mileage than how fast.ââ¬â¢ 3.2 Environmental Issues Another major factor of changing our system is environmental factors. Global warming is amongst one of the major factors, for example just burning a gallon of petrol when combined with oxygen; it produces almost 20 pounds of Carbon Dioxide CO2. The idea from moving to a more ââ¬Ëgreenââ¬â¢ vehicle from a conventional can literally reduce the number of greenhouse gases emitted by SI units. There have also been ways for awareness, such as energy rating for vehicles. The useful part we want is movement. We measure the weight of the vehicle and determine how much energy is being delivered to accelerate or maintain movement of the vehicle against external resistance. Then we could compare this to the amount of energy being put into the system. Useful power out over power input will give you the efficiency. As a result, the higher the CO2 emissions, the higher rate of road tax you will pay on the vehicle. Below is a diagram illustrating the CO2 emissions chart: Figure 1 At the end of the day, scientists and engineers are attempting to overcome obstacles, taking cars from the laboratory to the showroom, so that the first affordable and realistic car powered by hydrogen and pollution-free is driven by a child born today for their future. The government has pledged $1.7 billion in the U.S. for hydrogen research and development over the next five years, securing funding, however the objective is to overcome the obstacles involved in making hydrogen a viable energy source. There is a high significance of environmental benefits of hydrogen, whether individuals believe it or not, as facts are facts, hydrogen can be pollution-free and infinitely renewable through wind, solar and hydropower sources. Either way, the importance is high, I mean, how long can we keep surviving on ââ¬Ënon-renewableââ¬â¢ sources for? However, the phrase ââ¬Ënothing is free in this worldââ¬â¢ is true, in my opinion and you can not blame critics, who argue that the fuel source does have its environmental drawbacks; as they say, nothing is perfect. According to the National Hydrogen Energy Roadmap, it said that it requires up to 90 percent of all hydrogen has been refined from non-renewable sources, oil, natural gas and other fossil fuels. Does this mean weââ¬â¢re back to square one or is this just a stepping stone? So we agree that the extraction of hydrogen from fossil fuels may not be environmentally friendly, though once the hydrogen is in a fuel cell car, only water vapour and heat will be expelled from the exhaust. But it is the burning of the fossil fuels, which are used obtain the hydrogen and this releases carbon dioxide, which is the primary cause of global warming. Even some scientists say that the hydrogen which has been extracted from fossil fuels creates an impact of the environment by releasing carbon dioxide in the air, which defeats the point of a clean-energy provider. On the other hand, were bridges built with a perfect structure? Or were car engines primarily built efficiently? I think not, so my point is that we need to use current fossil fuels to perform trial and error, hence the term ââ¬Ëhybridââ¬â¢. But most importantly, this is all for the future and the main thing is that were making progressive now, whether it requires other sources of elements which contradict itself, though we just merely use it as a stepping stone. President Bushs 2004 budget asks for more than $22 million for hydrogen research and development to be devoted to coal, nuclear power and natural gas, and $17 million for renewable sources. Cutting RD for renewable sources and replacing them with fossil and nuclear doesnt make for a sustainable approach, said Jason Mark, director of the clean vehicles program for the Union of Concerned Scientists. A recent study warns of the danger of releasing hydrogen itself into the atmosphere. Los Alamos researcher Thom Rahn led a team of scientists from California universities and the National Centre for Atmospheric Research in Boulder, Colo. Their study of the natural cycle of atmospheric hydrogen was recently published in the British science journal Nature, and finds that substantially increased hydrogen production has the potential to damage the upper atmosphere. Escaped hydrogen could build up, depleting the ozone layer near the North and South poles and triggering an increase in global warming. The study also warns that hydrogen may further contribute to global warming by aiding other chemicals in producing increased amounts of water vapour in the upper atmosphere. It is impossible to manufacture, store and transport hydrogen without at least some fractional loss (to the atmosphere), Rahn said. Researchers from the California Institute of Technology estimate that leaked hydrogen in a hydrogen economy could cause as much as a 10 percent decrease in the stratospheric zone. If hydrogen replaces fossil fuels as the worlds main energy source, the researchers believe that each year 60 trillion to 120 trillion grams of hydrogen could be released into the atmosphere. This is four to eight times the amount that is currently released. The impact of increased hydrogen production depends on how well the earth adapts to the change. John Eiler, assistant professor of geochemistry at CalTech, said, This man-made hydrogen will either be absorbed in the soil a process that is still poorly understood but likely free of environmental consequences or will react with other compounds in the atmosphere. Determining which of these two processes dominates should be a solvable problem. Tracey Tromp, another CalTech researcher, contends that early recognition of problems will mitigate hydrogen fuels environmental flaws. If hydrogen emissions present an environmental hazard, then recognizing that hazard now can help guide investments in technologies to favour designs that minimize leakage, Tromp said. The CalTech researchers, like other scientists looking at the environmental impact of increased hydrogen production, believe that the sooner such problems are identified, the easier it will be to find solutions to make a hydrogen economy truly feasible. 4. Hybrid ââ¬â Environmentally Friendly 4.1 Benefits of a hybrid compared to a conventional The hybrid vehicle typically achieves greater fuel economy and lower emissions than conventional Internal Combustion Engine Vehicles (ICEV), resulting in fewer emissions being generated. These savings are primarily achieved by three elements of a typical hybrid design: Relying on both the engine and the electric motors for peak power needs, resulting in a smaller engine sized more for average usage rather than peak power usage. A smaller engine can have less internal losses and lower weight. Having significant battery storage capacity to store and reuse recaptured energy, especially in stop-and-go traffic, which is represented by the city driving cycle. Recapturing significant amounts of energy, whilst braking that are normally wasted as heat. This regenerative braking reduces vehicle speed by converting some of its kinetic energy into electricity, depending upon the power rating of the motor/generator. Other techniques that are not necessarily hybrid features, but that are frequently found on hybrid vehicles include: shutting down the engine during traffic stops or while coasting or during other idle periods; Improving aerodynamics; (part of the reason that SUVs get such bad fuel economy is the drag on the car. A box shaped car or truck has to exert more force to move through the air causing more stress on the engine making it work harder). Improving the shape and aerodynamics of a car is a good way to help better the fuel economy and also improve handling at the same time. Using low rolling resistance tyres were often made to give a quiet, smooth ride, high grip, etc., but efficiency was a lower priority). Tyres cause mechanical drag, once again making the engine work harder, consuming more fuel. Hybrid cars may use special tyres that are more inflated than regular tyres and stiffer or by choice of carcass structure and rubber compound have lower rolling resistance while retaining acceptable grip, and so improving fuel economy whatever the power source. Powering the A/C, power steering, and other auxiliary pumps electrically as and when needed; this reduces mechanical losses when compared with driving them continuously with traditional engine belts. These features make a hybrid vehicle particularly efficient for city traffic where there are frequent stops, coasting and idling periods. In addition noise emissions are reduced, particularly at idling and low operating speeds, in comparison to conventional engine vehicles. For continuous high speed highway use these features are much less useful in reducing emissions. 4.2à à Vehicle Emissions According to the EPA (Environmental Protection Agency), the recommended level for a typical passenger should equate to 5.5 metric tons of CO2. However, the three most popular hybrid vehicles have set a new standard by consistently reducing their emissions and surpassing the recommended levels. The vehicles are the Honda Civic, which produces 4.1 tons SI units, the Honda Insight at 3.5 tons SI units and last but not least, the Toyota Prius also being 3.5 tons SI units of CO2 emissions. 4.3 Buying a hybrid vehicle A hybrid car gets a much higher mileage, up to ten percent in some cases, and emits 97% less toxins into the environment than the average car. They are lighter and have a gentler impact on roads and soft terrain. With the price of gasoline soaring, a car that can run on both gas and electricity, depending on the circumstance, is a big advantage. Most people who decide to buy a hybrid car, however, cite a feel-good factor as their main reason for buying the car. It is their small way to contribute to a greener world. Despite all the benefits cited above, a hybrid car also has some downsides. For starters, they are expensive. A hybrid car tends to be more on average of à £3000, which is sometimes more expensive than a traditional car. They cost more to register, and repair costs tend to be hefty, as the entire car systems are intrinsically connected, and only expert mechanics can handle repairs. Parts may not be readily available, which could mean being without a car for a longer period as you is waiting for it to be repaired. 5.à Planning Schedule Gantt chart: Conclusion: The information gathered can be elaborated excessively, though I will quantify the relevant information where necessary. This preliminary report demonstrates how much of a positive impact hybrid vehicles have and how fuel efficiency in various sectors, such as fossil fuels andà global warming can be significantly reduced. As for hybrid vehicles themselves, it illustrates their efficiency in major development, for years to come. They have proven to be more effective than conventional vehicles and although they may be more expensive now, the long term effects are more beneficial.

Biography of John Napier, Scottish Mathematician
Biography of John Napier, Scottish Mathematician John Napier (1550-April 4, 1617) was a Scottish mathematician and theological writer who developed the concept ofà logarithms and the decimal point as a mathematical calculation method. He also had an influence in the world of physics and astronomy. Fast Facts: John Napier Known For: Developing and introducing the concept of logarithms, Napiers Bones and the decimal point.Born: 1550 at Merchiston Castle, nearà Edinburgh, ScotlandDied: April 4, 1617, at Merchiston CastleSpouse(s): Elizabeth Stirling (m. 1572-1579), Agnes ChisholmChildren: 12 (2 with Stirling, 10 with Chisholm)Notable Quote: Seeing there is nothing that is so troublesome to mathematical practice.... than the multiplications, divisions, square and cubical extractions of great numbers, which besides the tedious expense of time are... subject to many slippery errors, I began, therefore, to consider [how] I might remove those hindrances. Early Life Napier was born in Edinburgh, Scotland, into the Scottish nobility. Since his father was Sir Archibald Napier of Merchiston Castle, and his mother, Janet Bothwell, was the daughter of a member of Parliament, John Napier became the laird (property owner) of Merchiston. Napiers father was only 16 when his son, John, was born. As was the practice for members of the nobility, Napier did not enter school until he was 13. He did not stay in school very long, however. It is believed that he dropped out and traveled inà Europe to continue his studies. Little is known about these years, where or when he may have studied. In 1571, Napier turned 21 and returned to Scotland. The following year he married Elizabeth Stirling, daughter of Scottish mathematician James Stirling (1692-1770), and bat a castle at Gartnes in 1574. The couple had two children before Elizabeth died in 1579. Napier later married Agnes Chisholm, with whom he had ten children. On the death of his father in 1608, Napier and his family moved into Merchiston Castle, where he lived the rest of his life. Napiers father had been deeply interested and involved in religious matters, and Napier himself was no different. Because of his inherited wealth, he needed no professional position. He kept himself very busy by being involved with the political and religious controversies of his time. For the most part, religion and politics in Scotland at this time pitted Catholics against Protestants. Napier was anti-Catholic, as evidenced by his 1593 book against Catholicism and the papacy (office of the pope) entitled A Plaine Discovery of the Whole Revelation of St. John. This attack was so popular that it was translated into several languages and saw many editions. Napier always felt that if he attained any fame at all in his life, it would be because of that book. Becoming an Inventor As a person of high energy and curiosity, Napier paid much attention to his landholdings and tried to improve the workings of his estate. Around the Edinburgh area, he became widely known as Marvellous Merchiston for the many ingenious mechanisms he built to improve his crops and cattle. He experimented with fertilizers to enrich his land, invented an apparatus to remove water from flooded coal pits, and bat devices to better survey and measure land. He also wrote about plans to bad elaborate devices that would deflect any Spanish invasion of the British Isles. In addition, he described military devices that were similar to todays submarine, machine gun, and army tank. He never attempted to build any of the military instruments, however. Napier had a great interest in astronomy. which led to his contribution to mathematics. John was not just a stargazer; he was involved in research that required lengthy and time-consuming calculations of very large numbers. Once the idea came to him that there might be a better and simpler way to perform large number calculations, Napier focused on the issue and spent twenty years perfecting his idea. The result of this work is what we now callà logarithms. The Father of Logarithms and the Decimal Point Napier realized that all numbers can be expressed in what is now called exponential form, meaning 8 can be written as 23, 16 as 24à and so on. What makes logarithms so useful is the fact that the operations of multiplication and division are reduced to simple addition and subtraction. When very large numbers are expressed as a logarithm, multiplication becomes the addition ofà exponents. Example: 102à times 105à can be calculated as 10à 25à or 107. This is easier than 100 times 100,000. Napier first made this discovery known in 1614 in his book called A Description of the Wonderful Canon of Logarithms. The author briefly described and explained his inventions, but more importantly, he included his first set of logarithmic tables. These tables were a stroke of genius and a big hit with astronomers and scientists. It is said that English mathematician Henry Briggs was so influenced by the tables that he traveled to Scotland just to meet the inventor. This lead to a cooperative improvement including the development ofà Base 10. Napier was also responsible for advancing the notion of the decimal fraction by introducing the use of the decimal point. His suggestion that a simple point could be used to separate the whole number and fractional parts of a number soon became accepted practice throughout Great Britain.

For Cullen and Gilbert 'rehabilitation should be the major goal of any Essay
For Cullen and Gilbert 'rehabilitation should be the major goal of any correctional system'. Critically discuss this proposition - Essay Example In addition, the strengths and weaknesses are also imparted to be able to portray the potential gain of the whole system and even the limitations. The main view of Cullen and Gilbert can be considered as positive theories to answer the problems of criminology. Rehabilitation is the main objective that can be projected in relation to the effect of application in the behaviour of the detainees. The positive view of the theory can be considered as a priority in contrary to that of the old theories of justice that involve deterrence and retribution. Through the course of modern justice system, it can be considered that the role of rehabilitation on the reform of the offenders had taken the main road and had produced influence. The said influence had developed on the turn of the 1900s wherein the development and changing of the characteristics and the attitudes of the criminals and offenders had been projected as the main solution for the decrease of the number of crimes (Cullen and Gendreau, 2000). Through the 70ââ¬â¢s toward the end of the century, the effectiveness and the feasibility of the rehabilitation approach in the correctional systems had been criticized and questioned. Basically as the rehabilitation theory affirms that the crimes had been committed by the offenders on the basis of the problems in behaviour and inadequate decision making, critics believe that the process cannot help the society lessen criminals but there are dangers that rehabilitation cannot fully discipline the offenders. This can then pose danger to the welfare of the people (Wilson, 2005). In the presentation of the view of Cullen and Gilbert on the proper approach for correctional system, it is important to be able to present the different pros and cons. For that matter the criticisms of the rehabilitation theory is needed to be studied and scrutinized. The main scenario in the study undertaken by Cullen and Gilbert relates to the world in the

Reflect on the syndrome approach as a way to analyse complex systems Essay
Reflect on the syndrome approach as a way to analyse complex systems. How did it help - Essay Example In an attempt to reduce these nightmares another nightmare has been created. Hayden (2004) indicates that suburbia promised the ââ¬Ëtriple dreamââ¬â¢ of community, house and land with back yard pools and flowering trees. However, it has led to a rather complex problem. This is described as the ââ¬Å"Suburbia Syndromeâ⬠. The Suburbia Syndrome has been linked to a number of ills including obesity. The suburbia has also been linked to the crisis that unfolded in the recent past with the housing bust and the collapse of many financial institutions. Wasik (2009) has described the situation as the worst housing bust of all times and has linked it the realization of the American dream. The quest by every American to live in the suburbs is unsustainable as there is a connection between, economics, home ownership and the environment. The price of energy and other factors make it very clear that the present course of suburbia is unsustainable. Suburban conditions have been linked t o a situation of wastefulness and unsustainability. Jackson (1985, cited in Hayden 2004) indicated that the lengthy process of suburbanization would slow down because of rising energy and land costs which would lead people back to urban centers. However, this was not to be as ââ¬ËAmericans have settled on the fringes of metropolitan regionsââ¬â¢ much faster than they have ever done (Hayden 2004). More Americans were living the suburbs in 2000 than those living in central cities and rural areas combined (Hayden 2004). Many of the key economic and cultures centers including corporate headquarters and regional theaters had relocated to the suburbs. This was so while space was becoming more abundant in the urban centers. This indicates moving from one problem to another as the move to relieve the urban centers of certain problems have created the same problems elsewhere. Once a suburban area has been established the promoters

Art on Japanese Art History Essay Example for Free
Art on Japanese Art History Essay How can the artistic medium one chooses to use to express oneself determine whether or not it is truly art? While digital artistsââ¬â¢ artistic ability is often questioned and the credit is given to the computer being used, the art itself springs from the mind of the digital artist. I can say this with personal fervor: Digital art is truly in essence a form of art that merely takes advantage of the innovations of modern technology. Digital Art isnââ¬â¢t computer-generated. While it might involve using tools offered by specialized computer programs a computer doesnââ¬â¢t do the thinking for you, and the creative ideas put forth are of the artistââ¬â¢s mind. Digital artistââ¬â¢s only use computer tools to convey their designs, all of the creative credibility should be given to the artist himself. Should the canvas the Mona Lisa was painted on be considered the creator of the masterpiece or rather Leonardo Da Vinci? Painters that stick to canvas are limiting themselves to the paint they use and the cotton woven fibers of their canvas. Why purposely choose to ignore the modern day tools that are given to you and condescendingly look down upon those who choose to utilize them? Over the years, I have spent a lot of my own time experimenting in the depths of digital art. Many times, I have used the computer as a medium for self expression; from creating to pictures on Microsoft paint as a child to experimenting with specialized software such as Adobe Photoshop. I have a deep and passionate love for creating and expressing myself through artwork on the computer. I one day aspire to have a profession in the field of digital art, such as a Graphic Designer. Because of this, I am very offended by the comments I hear from ââ¬Å"traditional artistsâ⬠that condescend digital art for its use of the computer as the artistic medium. When I hear comments that degrade digital artwork to computer-generated images, as though the computer itself designed the art I feel enraged and cheated. The other day a friend of mine ignorantly explained to me that she could, given the proper software, create her own masterpiece without any prior experience in digital art, as though anyone if given the proper software could instantaneously create masterpieces, when really there is so much more to digital art than computer software or the computer itself. Itââ¬â¢s about oneââ¬â¢s individual artistic talents. To me that would be the equivalent of saying that if I were given a canvas and a paintbrush I could instantaneously create a masterpiece, which I know is false and ignorant. Art is ââ¬Å"the use of skill and imagination in the creation of aesthetic objects, environments, or experiences that can be shared with othersâ⬠(Britannica). Digital art is a general term for a range of artistic works and practices that use digital technology as an essential part of the creative and/or presentation process. There are many different employment fields in digital art. A couple of examples are graphic design and web design. Graphic design is the process and art of combining text and graphics and communicating an effective message in the design of logos, graphics, brochures, newsletters, posters, signs, and any other type of visual communication. Famous Graphic Designer, Milton Glaser, says ââ¬Å"to design is to communicate clearly by whatever means you can control or master. â⬠A graphic designer would meet with his/her clients and discuss the type of visual communication the client is interested in. The client may provide a general idea for the design, but the creative options are left for the designer to decide how to best portray the message of the client. The designer would then either sketch out a design to scan on to the computer for further alterations or go directly to the computer software in order to design the desired product. The designer would then verify with the client for satisfaction of the product. Web Design is the art and process of creating a single Web page or entire Web sites and may involve both the aesthetics and the mechanics of a Web siteââ¬â¢s operation although primarily it focuses on the look and feel of the Web site the design elements. ââ¬Å"To be effective, the interfaces for online information systems must be as rich and flexible as the physical environments they replace. They must not only supply a direct path to reach the users goals, but must be able to accommodate different approaches to the task. This means that the interface design must not only organize the content for easy access, but must incorporate the right combination of technologies and interaction techniques to allow the user to work in their own styleâ⬠(Quesenbery). A Web Designer would be sought out by a client in need of assistance in designing a website or website layout, usually for advertising and communicative purposes of the client. Like in Graphic design, the client may provide the designer with a general idea or guideline for the product, however, web designers must understand the dynamics of coding and html. Traditional art is understood to include things such as paintings, sculptures, and hand-drawings; basically any art which involves physical activity, usually of the hands. Famous Traditional Artists include: Leonardo DaVinci, Vincent Van Gough, and Andy Warhol. These artists use drawings and paintings as their forms of self expression which led to their innovative masterpieces: the Mona Lisa, Starry Night, and Pop Art, respectively. Traditional artists often look down upon the usage of the computer as the creative medium utilized when expressing oneself in art. Some believe that using a computer negates the creative ability of the artist and is the less credible form of art. Using computers in order to create art is sometimes seen as the easier method involving little artistic ability. ââ¬Å"For artists diving into a new technology, it is a triple short-cut to mastery: you get a free ride on the novelty of the medium; there are no previous masters to surpass; and after a few weeks, you are the masterâ⬠(Brand). There is a certain type of beauty in a hand-painted piece of art. The same is true for a masterfully drawn illustration. For this there is no substitute. Traditional art is the oldest form of art and could be considered the foundation of art. Many people consider this form of art to require the highest level of skill and creative ability, and that there is no other type of art form that can surpass it. There are a large number of people that believe this form of art is most vital, and that digital art simply shouldnââ¬â¢t be considered art due to the use of technology rather than their hands. Opponents of digital art argue that there is no skill in ââ¬Å"pointing and clickingâ⬠on a computer screen. ââ¬Å"I would rather choose the painting of a monkey over anything generated electronically, because I am more fascinated by the direct evidence of a mind at work than I am by the output of machinesâ⬠(Glenn). Because of this belief, there is a good bit of animosity between the two different sects. Traditional artists feel as if they are protecting art in its truest form, whereas digital artists feel as if they are exposing the world to a newer and more advanced form of art infinitely full of possibilities. While traditional art is the older and more revered art form, that doesnââ¬â¢t mean that digital art is any less of an art. Both art forms require talent, precision, technique, and creativity from the artist. Digital artists are just as legitimate of artists as traditional artists. It is simply ignorant and petty to distinguish digital art as separate from true art in essence. Yes, computers are used as the medium for expression, however, like previously stated, that doesnââ¬â¢t mean that the computer creates the ideas and designs. The designs and creativity come from the artist and the computer is simply another way to release the idea from the artistââ¬â¢s mind, similar to a piece of paper or canvas. Digital art should be just as revered as traditional art because the amount of creativity and artistic ability is equal in both forms.

Experiencing Slavery Through Octavia Butlers Kindred Essay -- Octavia
Authors of fiction often write about the human condition as a way to connect with a broad range of readers. Unlike factual textbooks, fiction gives characters feeling and emotion, allowing us to see the story behind the basic details. In many cases, readers gain a new perspective on a period of time by examining a fiction novel. In Kindred, by Octavia Butler, the near death experiences of Rufus Weylin transports a 20th century African American woman named Dana to the ante bellum South to experience exactly what itââ¬â¢s like to be a slave. Through her day-to-day life on the Weylin plantation, the reader begins to understand just how complex slavery is and how it affects both the slaves and the plantation owners; thus, giving new meaning and an added sense of realism to this 19th century practice of exploitation. On the surface, slavery was a system in which Africans were bought and sold as property. However, by reading Kindred, the reader begins to realize that the system was much more complex. In other words, both plantation owners and slaves focused on retaining their property or staying alive, respectively. Butler illustrates this throughout the text. Seen as inferior and subhuman by whites, slaves were often only able to trust and rely on each other. When Dana is transported to the 19th century, she realizes her need to escape. However, the only way she can do this is by allowing Rufus to lead her in the right direction. As he does this, she wonders whether he is setting a trap for her. She says, ââ¬Å"I realized suddenly how easy it would be for him to betray meââ¬âto open the door and run away or shout an alarmâ⬠(32).

College on Campus VS Online Essay
So, you have decided you want to go to college. Do you know what your options are? Read on to get a brief look at what these options have to offer and see what the pros and cons of each choice are. Every student is different and is looking for the type of college that fits them the best. Learning style and personal study preferences tend to assist in making the right choice. Attending college on a campus or online have similar outcomes but differ in how students attend class, complete class work, and interact with teachers and classmates. The decision is yours to make. Whether a student decides to attend a campus or remain at home and attend classes online they still have to go through the same basic processes. Look into and choose a school, pick the desired major, apply for financial aid, and start classes. With either choice there will be professors to teach all the different classes. Some professors might not be as enjoyable as others, and it does not really matter if the student meets them in person or not. There will also be other students of all ages attending the same classes; they will have the opportunity to interact with and get to know each other either face-to-face or through messages on the computer. Attending college online and on campus offers the same or equivalent classes that include books, that have to be read and discussed with the class, homework that will have to be completed and turned in, and the students still have to show up for class and participate. Whichever choices, the student will take and complete all sorts of class es and eventually graduate with a degree of their choosing. Along with things in common, campus and online college also have many differences that need to be taken into account before making a final decision. Getting to campus can be difficult, the student would have to drive, take a bus, or a cab. This makes going to school even more expensive, paying for gas or paying fees to use public transportation add to the cost of school. Staying home and attending class online becomes the cheaper option, even if tuition is usually slightly higher. This is one of the big differences to consider. Another important variance to make sure is considered is whether they want to have everyday interactions with classmates and professors. If they choose to attend online classes almost all communication is done via the Internet. However there is the option of calling their teachers if needed. As for relating with classmates daily, this is all done within the virtual classroom; however, they do not get to ââ¬Å"meetâ⬠the people they are in class with. Attending class is also very different, on a campus students have to get up in the morning and get dressed, they have to be presentable when going to class, and this takes time. Then they have to drive to the school, get to class before it starts at whatever designated times are given, and then sit there for lectures and discussions. With online college they are able to save their gas money, sit at home in their pajamas, and attend class whenever it is convenient. There are no set class times, and they do not have to go anywhere. Doing and turning in assignments is also something that is usually different. At a college campus many of the assignments will be done on paper and handed in to the professors. Online all class work is done and turned in on the computer by submitting them on the schoolââ¬â¢s website. Another thing about attending online classes is whichever degree program is chosen the student typically only take classes toward that degree. Elective classes can be taken online, but they are not commonly included in the degree programs because taking classes online are supposed to be a faster way to get to the degree the student wants. If attending a campus they will more than likely have more opportunities to attend these extra classes. Also not included when attending college online is the ability to join clubs or participate in school functions such as sports or other school events. This is a great deal of information to process and think about, but we are not done yet. Knowing the similarities and differences between these types of colleges are not all that needs to be considered. Students need to think about their lifestyle and which type of college will fit their daily lives. One of the main things to think about is what kind of schedule they have. If they work full or part time they will have to figure out how to work in a school schedule. Depending on if they are single, married, or have children, also affects when, how, and where they can attend school. What activities and other obligations they have planned week to week also make fitting school time in difficult. These are all things that have to be thought about while planning how and where to attend college. Another factor that has to be taken into account is how the person learns. What is their learning style? There are many ways a person can learn, such as by reading and taking notes or seeing the action taking place. Some students need to have someone speak about what they are learning, such as a lecture. Some people need to work in a group; others do better at learning alone. Knowing the best way they learn will assist in deciding how they will take classes. When attending college at a campus they will be going to classes and listening to lectures, reading class material, and doing assignments, some on their own and some in groups. Online classes require the student to attend class on their own, when they can but still make attendance and participate. They have to be the type of person who can make time to attend class and do the assigned work without someone telling them to do it. As an online student they have to manage their own schedule and make sure all assignments are turned in on time. They have to know themselves and what they can do to accomplish their goals. Deciding how and where to go to college is a tough one. You have to take a great deal of information into consideration. The social and class opportunities given at a campus are a definite plus, but they have to be worth the extra time and money needed to get to and from school. By going to college at a campus it may also take you longer to get to your degree goal. Attending a campus can also take time away from family and friends. If you have a busy lifestyle with work, children, or other obligations; going to college online might be a better choice for you. You can get your degree faster and be able to achieve your dreams in a timelier manner. Have you made a decision yet? Probably not, but you will. Keep in mind that you are doing this for you and no one can make this decision for you. Some advice for you is to do your research. Go visit some college campuses, surf the web for schools that offer online classes for the degree that you want, and donââ¬â¢t settle for the first school you look into, whether it is online or at a campus. Know what you want out of college, do you want to fast track, or take your time and get all you can out of the experience? Once you contemplate what you want and how you want to get it the rest will fall into place.

Howard Hendricks Essay Example
Howard Hendricks Essay Example Howard Hendricks Paper Howard Hendricks Paper Howard G. Hendricks, the author of Teaching to Change Lives, earned his B. A., Wheaton College, 1946; Th. M. , Dallas Theological Seminary, 1950; D. D. , Wheaton College, 1967; graduate study, Dallas Theological Seminary, Wheaton College Graduate School, Biblical Seminary in New York and has been a professor at Dallas Theological Seminary for over fifty years. He has a passion for teaching and it show in this book. Dr. Hendricks presents us with seven laws or principles rules for teaching. Summary Dr. Hendricks has presented to all who take the time to read this book a tool that will enable even the most seasoned teacher an avenue for change that will improve, not only their teaching skills, but enhance the learning skills of the their students. This book is base on seven easy to understand proven principles that enable direct application from the book to the classroom. These principles are as follows; The Law of the Teacher, of Education, of Activity, the Law of Communication, of the Heart, of Encouragement, and the Law of Readiness. The first of these principles the Law of the Teacher states, ââ¬Å"If you stop growing today you stop teaching tomorrow. â⬠He also shares a philosophy that should be adopted buy all. Hendricks says, ââ¬Å"that I, as a teacher, am primarily a learner, a student among students. I am perpetuating the learning process; I am still en route. And by becoming a student again, I as a teacher will look at the education process through a radically new- and uniquely personal- set of eyes. Chapter Three The Law of Activity caught my attention. Its states, ââ¬Å"Maximum learning is always the result of maximum involvement. It was if God was saying this is you and I believe this holds true for everyone as long as the student values the activity. One example that I believe he talked about and is near and dear to my heart is evangelism. You can teach an evangelism class and you can teach how to evangelize people, but it doesnââ¬â¢t mean you will be successful. You have to be active and get out and witness. One area that troubles me that he may have not elaborated enough is under the Law of Teaching page 29. He talks about not labeling kids, which I agree, but, in this same section, it also talks about how they come into our church excited and energetic and we get on to them. I have worked with these kids and they need structure and discipline and a firm hand sometimes however, it should always be done with the love of Christ. Conclusion This book is not only for the experienced teacher but for the novice as well. All can and will benefit from this book. One can tell that Hendricks is very enthusiastic about teaching and helping the learner to learn especially when it comes to the spiritual aspect of teaching. I believe that the seven laws, implemented properly, will allow every teachers, pastors, and laypersons the opportunity to impact the lives of people for Kingdom of Heaven. This is a must read for anyone, especially for those in ministry.

The Meaning of Innuendo, Definition and Examples
The Meaning of Innuendo, Definition and Examples Innuendo is a subtle or indirect observation about a person or thing, usually of a salacious, critical, or disparaging nature. Also called insinuation. In An Account of Innuendo, Bruce Fraser defines the term as an implied message in the form of an allegation whose content constitutes some sort of unwanted ascription towards the target of the comment (Perspectives on Semantics, Pragmatics, and Discourse, 2001). As T. Edward Damer has noted, The force of this fallacy lies in the impression created that some veiled claim is true, although no evidence is presented to support such a view (Attacking Faulty Reasoning, 2009). Pronunciation à in-YOO-en-doe Etymology From the Latin, by hinting Examples and Observations The informal fallacy of innuendoà consists of implying a judgment, usually derogatory, by hinting. No argument is offered. Insteadà theà audience is invited by suggestion, by a nod and a wink, to make the assumption. Someone asks, Where is Jones? Did he get fired or something? Someone answers, Not yet.à By innuendo, the responseà numbers Joness days. The political candidate who distributes a brochure promising to restore honesty and integrity to an office has suggested, without presenting any argument, that the incumbent is crooked. - Joel Rudinow and Vincent E. Barry,à Invitation to Critical Thinking, 6th ed. Thomson Wadsworth, 2008 Sexual come-ons are a classic example [of innuendo]. Would you like to come up and see my etchings? has been recognized as a double entendre for so long that by 1939, James Thurber could draw a cartoon of a hapless man in an apartment lobby saying to his date, You wait here, and Ill bring the etchings down.ââ¬â¹ The veiled threat also has a stereotype: the Mafia wiseguy offering protection with the soft sell, Nice store you got there. Would be a real shame if something happened to it. Traffic cops sometimes face not-so-innocent questions like, Gee, Officer, is there some way I could pay the fine right here? - Steven Pinker, Words Dont Mean What They Mean, Time, September 6, 2007 How to Detect Innuendo To detect innuendo, one has to read between the lines of the written or spoken discourse in a given case and draw out by implicature conclusions that are meant to be inferred by a reader or audience. This is done by reconstructing the argument as a contribution to a conversation, a conventionalized type of dialogue, in which the speaker and hearer (or reader) are supposedly engaged. In such a context, speaker and hearer may be presumed to share common knowledge and expectations and cooperatively to take part in the conversation at its different stages, by taking turns making kinds of moves called speech acts, for example, questioning and replying, asking for clarification or justification of an assertion. - Douglas Walton, One-Sided Arguments: A Dialectical Analysis of Bias. State University of New York Press, 1999 Erving Goffman on the Language of Hint Tact in regard to face-work often relies for its operation on a tacit agreement to do business through the language of hintthe language of innuendo, ambiguities, well-placed pauses, carefully worded jokes, and so on. The rule regarding this unofficial kind of communication is that the sender ought not to act as if he had officially conveyed the message he has hinted at, while the recipients have the right and the obligation to act as if they have not officially received the message contained in the hint. Hinted communication, then, is deniable communication; it need not be faced up to. - Erving Goffman, Interaction Ritual: Essays in Face-to-Face Behavior. Aldine, 1967 Innuendo in Political Discourse Some seem to believe that we should negotiate with the terrorists and radicals, as if some ingenious argument will persuade them they have been wrong all along. We have heard this foolish delusion before. - President George W. Bush, speech to the members of the Knesset in Jerusalem, May 15, 2008 Bush was speaking of appeasement against those who would negotiate with terrorists. The White House spokeswoman, with a straight face, claimed the reference was not to Sen. Barack Obama. - John Mashek, Bush, Obama, and the Hitler Card. U.S. News, May 16, 2008 Our nation stands at a fork in the political road. In one direction, lies a land of slander and scare; the land of sly innuendo, the poison pen, the anonymous phone call and hustling, pushing, shoving; the land of smash and grab and anything to win. This is Nixonland. But I say to you that it is not America. - Adlai E. Stevenson II, written during his second presidential campaign in 1956 The Lighter Side of Sexual Innuendo Norman: (leers, grinning) Your wife interested in er . . . (waggles head, leans across) photographs, eh? Know what I mean? Photographs, he asked him knowingly. Him: Photography? Norman: Yes. Nudge nudge. Snap snap. Grin grin, wink wink, say no more.

Kinect Essay Example | Topics and Well Written Essays - 500 words
Kinect - Essay Example With the development of the Nintendo Wii and the PlayStation Move, Xbox needed a suitable competitive product to secure its market share. As a result, the company had to expand the product lines current competencies and develop new technology in order to obtain the desired product capabilities. The software behind connect was a necessary change in game development for Xbox in order to compete with its competitors. The Kinect technology is based upon a software technology developed internally by Rare, a subsidiary of Microsoft Game Studios.
