Mother Of Invention Essays - Thomas Edison, Deists, General Electric

Mother Of Invention Necessity is the mother of invention? or is it? The real mother of invention is not necessity, but curiosity. From the discovery of electricity, the invention of the light bulb, car, airplane, and air conditioning to Global Positioning Satellite systems curiosity has been the reason behind the invention. One of the greatest discoveries ever was the discovery of electricity. Ben Franklin has been given the most credit for the discovery of electricity. Before the legendary kite experiment in 1752 electricity was a known force of nature, but it had not been thoroughly studied. Even after that Franklin did not know what potential his discovery of electricity had. It is said that he once tried to kill a Christmas turkey with electricity, but accidentally made contact with the current and received a nice shock. As time progressed Franklin created more and more electrical devices including the battery and the lightening rod (Thinkquest.org). These inventions were discovered through theories and hypothesis that Franklin thought might be true and he tried them and they worked. All of these things are nice, and today people probably would have difficulty living without them, but at the time in the mid-1700's people had no need for electricity. There is another wonderful invention called the incandescent light bulb. Thomas Edison was a professional inventor. He wanted to see if he could create a better way to light a home that with candles or lamps. And so Edison invented the incandescent light bulb. Edison tried to come out with an invention every ten days. This invention came about in October 1879 (Thomas Edison birthplace Museum). Although people wanted another way to light their homes they did a fine job by using torches and lamps. They had a want for something better, but not a need for a light bulb. The invention of the air conditioning unit is a very popular one here in Phoenix. This again was not a necessity; in fact even today it is not a necessity it is actually a luxury. In 1902, after earning a Master's degree in Electrical Engineering from Cornell University Willis Carrier invented the first air conditioner. He wanted to see if there was a more efficient way of cooling air and making the air cleaner than what the current ventilation systems could do. This was a great invention because before the air conditioner people had good ventilation systems to cool off buildings and this worked somewhat. The air that came in would smell like the vents and the air wasn't really cooled. But with the air conditioning not only could you control the air temperature, but you could also control the humidity. This was good for scientific experiments (MIT's Invention Demention website). Even though the air conditioning was a great invention, it is not a necessity. People can and do live with out air conditioning units in both cars and homes, they may sweat a lot but they do live. Another great invention was that of the car. At the time that the car was invented people got around by horse and carriage, or by foot. This was the socially accepted means of travel and people did not need anything more than a way to get from point a to point b. In 1896 Henry Ford built his first automobile. Ford wanted to see if he could make a faster means of travel. In 1903 Ford established the Ford Motor Company. He revolutionized the world with his assembly lines, and the low cost of his cars. His first car the Model T is very well known and for around $200 was affordable. Ford paid their workers an unheard of $5 a day which meant that a worker could afford to buy the cars that they made (National Inventors Hall of Fame website). Although I like my car a lot and I know that many people couldn't function without their cars, but when Ford invented the car if you wanted to get somewhere you either walked or you rode a horse making the car not a necessity. The invention of the airplane was a revolutionary one. The Wright brothers invented the airplane in 1903. The Wright's wanted to see if it was possible for man to

Fantastic Mr Fox Quotes

'Fantastic Mr Fox' Quotes Fantastic Mr Fox is a trickster-adventure story by British author Roald Dahl. Mr. Fox is (of course) fantastic, he faces seemingly impossible odds to survive. His shenanigans become legendary as he outwits three devilish rich men in order to steal food. The book was turned into a popular movie of the same name in 2009 with George Clooney voicing the lead character. Both the book and the movie have been popular with children.   Quotes from Fantastic Mr. Fox Down in the valley, there were three farms. The owners of these farms had done well. They were rich men.

Concrete Homes - Best Bet on a Windy Day

Concrete Homes - Best Bet on a Windy Day When hurricanes and typhoons howl, the greatest danger to people and property is flying debris. Carried at such intense velocity, a 2 x 4 piece of lumber will become a missile that can slice through walls. When an EF2 tornado moved through central Georgia in 2008, a board from an awning was ripped off, took flight across the street, and impaled itself deep into an adjacent solid concrete wall. FEMA tells us this is a common wind-related event and recommends the building of safe rooms. Researchers at the National Wind Institute of Texas Tech University in  Lubbock have determined that concrete walls are strong enough to withstand flying debris from hurricanes and tornadoes. According to their findings, homes made of concrete are much more storm-resistant than houses constructed of wood or even wood studs with steel plates. The ramifications of these research studies are changing the way we build. The Research Study The Debris Impact Facility at Texas Tech is well-known for its pneumatic cannon, a device capable of launching various materials of different sizes at different speeds. The cannon is in a laboratory, a controlled environment, To duplicate hurricane-like conditions in the laboratory, researchers shot wall sections with 15-pound 2 x 4 lumber missiles at up to 100 mph, simulating debris carried in a 250 mph wind. These conditions cover all but the most severe tornadoes. Hurricane wind speeds are less than the speeds modeled here. Missile tests designed to demonstrate damage from hurricanes use a 9-pound missile traveling about 34 mph. Researchers tested 4 x 4-foot sections of concrete block, several types of insulating concrete forms, steel studs, and wood studs to rate performance in high winds. The sections were finished as they would be in a completed home: drywall, fiberglass insulation, plywood sheathing, and exterior finishes of vinyl siding, clay brick, or stucco. All of the concrete wall systems survived the tests with no structural damage. Lightweight steel and wood stud walls, however, offered little or no resistance to the missile. The 2 x 4 ripped through them. Intertek, a commercial product and performance testing company, has also done research with their own canon at Architectural Testing Inc. They point out that the safety of a concrete home can be deceptive if the house is built with unreinforced concrete block, which offers some protections but not total. Recommendations Reinforced concrete homes have proven their wind-resistance in the field during tornadoes, hurricanes, and typhoons. In Urbana, Illinois, a home constructed with insulating concrete forms (ICFs) withstood a 1996 tornado with minimal damage. In the Liberty City area of Miami, several concrete form homes survived Hurricane Andrew in 1992. In both cases, neighboring homes were destroyed. In the fall of 2012, Hurricane Sandy blew apart the older wood construction homes on the New Jersey coast, leaving alone the newer townhouses built with insulating concrete forms. Monolithic domes, which are made of concrete and rebar in one piece, have proven especially strong. The sturdy concrete construction combined with the dome shape make these innovative homes nearly impervious to tornadoes, hurricanes, and earthquakes. Many people cannot get over the look of these homes, however, although some brave (and wealthy) homeowners are experimenting with more modern designs. One such futuristic design has a hydraulic lift to actually move the structure below the ground before a tornado strikes. Researchers at Texas Tech University recommend that houses in tornado-prone areas build in-residence shelters of either concrete or  heavy gauge sheet-metal. Unlike hurricanes, tornadoes come with little warning, and reinforced interior rooms can offer more safety than an exterior storm shelter. Other advice researchers offer is to design your home with a hip roof instead of a gable roof, and everyone should use  hurricane straps to keep the roof on and the timbers straight. Concrete and Climate Change - More Research To make concrete, you need cement, and its well-known that the manufacturing of cement releases great amounts of carbon dioxide into the atmosphere during the heating process. The building trade is one of the largest contributors to climate change, and cement makers and the people who purchase their product are some of the largest contributors to what we know to be greenhouse gas pollution. Research on new production methods will no doubt be met with resistance from a very conservative industry, but at some point consumers and governments will make new processes affordable and necessary. One company trying to find solutions is Calera Corporation of California. They have focused on recycling CO2 emissions into the production of a calcium carbonate cement. Their process uses the chemistry found in nature - what formed the White Cliffs of Dover and the shells of marine organisms? Researcher David Stone accidentally discovered an iron carbonate-based concrete when he was a graduate student at the University of Arizona. IronKast Technologies, LLC is in the process of commercializing Ferock and Ferrocrete, made from steel dust and recycled glass. Ultra-high-performance concrete (UHPC) known as Ductal ® has been used successfully by Frank Gehry in the Louis Vuitton Foundation Museum in Paris and by architects Herzog de Meuron in the Pà ©rez Art Museum Miami (PAMM). The strong, thin concrete is expensive, but its a good idea to watch what the Pritzker Laureate architects are using, as they are often the first experimenters. Universities and government entities continue to be the incubators for new materials, researching and engineering composites with different properties and better solutions. And its not just concrete  - the U.S. Naval Research Laboratory has invented a glass substitute, a transparent, tough-as-armor ceramic called spinel (MgAl2O4). Researchers at MITs Concrete Sustainability Hub are also concentrating their attention on cement and its microtexture  - as well as the cost-effectiveness of these new and expensive products. Why You Might Want to Hire an Architect Building a home to withstand natures fury is not a simple task. The process is neither a construction nor design problem alone. Custom builders can specialize in insulated concrete rorms (ICF), and even give their end-products safe-sounding names like Tornado Guard, but architects can design beautiful buildings with evidence-based material specifications for builders to use. Two questions to ask if you are not working with an architect are 1. Does the construction company have architects on staff? and 2. Has the company financially sponsored any of the research testing? The professional field of architecture is more than sketches and floor plans. Texas Tech University even offers a Ph.D. in Wind Science and Engineering.

Adult Training in Canada Article Example | Topics and Well Written Essays - 1000 words

Adult Training in Canada - Article Example Standard of living depends on the skills of the labor force. Thus, any nation’s economy depends upon the skills that the labor force possesses. Education and training are lifetime activities related to the working career but it is difficult to evaluate the training decisions based on the business cycle as there are many other factors that influence the training decisions. As labour market conditions improve it becomes essential to train the workforce. Training is influenced by the ‘business cycle’. As business activity increases hiring too has to increase because businesses require more staff. The staff also needs to be trained and hence as employers add staff they also undertake to train the staff. However, the ‘opportunity cost’ in training the staff is higher in a robust economy and this can reduce the incidence of training. However these are counterbalancing influences which make it difficult to relate training to business cycle. A thorough study would entail examining the entire workings of the Canadian economy which is a long-drawn process. The authors decided to restrict their query to evaluate whether the AETS instruments provide a consistent explanation of training incidence and duration for both men and women. Overall education level increased between 1992 and 1998 and more women opted for university degree. Several factors suggest that training too should have increased during this period. Based on the human capital model training should increase. Besides, between 1994 and 1998 business activity and employment rose, and this also is an indicator of rise in training. However, an aging population would imply reduced training levels. Besides, data analysis revealed changes in several factors that influence training levels. As the education level rose, people became more urban. Lifestyle changed resulting in delayed marriages and late children; men keeping out of unionism and preferring to be in employment rather than be self-employed. Men preferred to work for larger but private firms while women preferred the public sector. All these make it difficult to deduce the training duration and incidence based on the economy and business cycles. This gives rise to the query as to what factors influence an individual to undertake training. The authors draw a parallel between the human capital and the physical capital. Just as the stock and quality of physical capital comprising of machinery, equipment and computers can be augmented through investments, human capital too can be upgraded through training activities. Adults may undertake training for various reasons. This could range from a simple desire to upgrade skills after an absence from job market to desire for career advancement. Participation in training can occur at all stages in the life cycle of an individual. Thus, based on these probabilities, this study evaluated the factors that influence training decision. It further describes the incidence o f training activity during the 1990s among adult Canadians who were not part- or full-time students in any education program. The study is based on a core model of human capital accumulation over the life cycle. Various factors that influence training participation and duration were taken as the variables in this study. These include age, job tenure, hours worked and past education level. The control variables included in the study were sex, family circumstances, region of residence and firm size. Data pooled from 1992, 1994 and 1998 Adult Education and Training Surveys (AETS) were statistically analyzed. The AETS survey (1998) was the sixth in the series but for this study only the data from three surveys were compiled. The purpose of AETS was to measure participation rates for learning and training

Stress in R.C. Sherriffs Journeys End Essay -- Journeys End Essays

World war I broke out in 1914 and lasted until 1918 when the armistice was signed. Throughout this period great destruction was suffered across the world and in particular in 1918 when the German army was preparing a massive attack against the allies. 'Journey's End' was written by R.C.Sherriff in 1928. It is set in the British trenches a few days before the expected attack and Sherriff re-creates the moments leading up to it. This drama is based upon Sherriff's real-life experiences as he himself was a captain of the East-Surrey regiment and played a part in the First World War. Sherriff's understanding of the relationships between men and the morale of soldiers living in the confines of the trenches are portrayed through the characters features in the play. Sherriff's purpose when writing the play may have been to celebrate the ten year anniversary as there were floods of memoirs, poems and reminiscences coming out around this time, however he may have more importantly wanted to ensure that war doesn't break out again by illustrating the pain and hopelessness he endured at was to convince his audience. 'Journey's End' gives the reader/audience a clear insight into the reality of life at war and explores the harsh conditions experienced by the men/officers at the front line. Despite Sherriff's ability to re-create the soldiers lives, staging the play is a main difficulty in which many things would need to be considered before-hand such as the audience he is targeting, sound, lighting and props. It is vital that what happens on stage is realistic to the audience so that their interpretations of trench conditions is genuine. He would also need to make things realistic as he may well find that ex s... ...ers died when the trench collapsed including Raleigh however we are still unsure about what happened to Stanhope, Hibbert or trotter. The death of Raleigh's character symbolises the appalling waste of lives during World War 1 but it also has an intense moving effect on the audience. We had warmed to him at the beginning of the play because of his eagerness and excitement however he never realised the full extent of war until the raid. I think that Sherriff's message was to show people the effects of war on soldier's minds. Stanhope's character was a prime example of this as he was psychologically damaged by the effects of war. I also feel that Sherriff had a hidden message of wanting to convey the full scale horror of war, both physically and mentally. A small disagreement between two countries or two opposing sides can result in a massive loss of life.

DNA Science Technology Essay

Recombinant DNA Technology has been used to create different types of medicines for example human insulin. People with diabetes do not produce enough insulin for their own bodies, and in a lot of cases, they are allergic to non-human insulin. Due to the creation of Recombinant DNA Technology, scientists are able to produce such insulin in laboratories. The process for creating this insulin starts with isolating the gene from the human cells. Then after it has been isolated, it is then inserted into plasmids. From there the plasmids are introduced into bacterial cells. These cells manufacture the insulin protein based on the human code. The final, purified product is identical to human insulin and non-allergenic. In some cases though, yeast is used in recombinant DNA technology in creating human insulin instead of using bacteria. Since Yeast performs more complicated cellular processes that occur in human cells, it is more useful in producing human substances. This technology is also used in producing genetically modified foods. Genes can be produced from plants or other organisms in order to give them certain characteristics such as, giving produce a longer shelf life, increasing the flavor of the foods and even the nutritional content, and creating edible vaccines in order to prevent widespread diseases in other developing countries. The technology of making genetically modified foods and creating human insulin are very similar, with one additional step. After the bacteria multiply the selected gene, scientists introduce it into plant cells. This is done so that the plant will produce the gene product; no matter if it is an insecticide, vaccine, or other plant material. Until writing about this, I was unaware of the role that Recombinant DNA technology actually plays into our daily life and the effects it takes on our health and well-being, as well as the produce that we buy in the stores and eat on a daily basis. Now that I have done this I am more aware of how much Recombinant DNA technology helps us as far as making insulin for diabetics so that they can hopefully live longer lives, and making our foods not only healthier but even tastier. In conclusion, Recombinant DNA technology has made a huge difference in our society today, and I believe that we are much better off in many with it. This technology not only saves diabetics lives, but keeps our whole nation/world as a whole much healthier than we’ve ever been.
