Education Through Imagination Essay Example for Free

Education Through Imagination Essay William Butler Yeats said, â€Å"Education is not filling a bucket but lighting a fire.†(The Language of Composition, Yeats page 174) As a high school student aspiring to be an actress, I most certainly agree with his intelligent statement. Education to me, just as to Yeats, is not about having the maximum capacity of knowledge in every subject; it is finding that burning desire to learn about whatever it is that interests you. It is unnecessary to fill our heads with facts that will essentially be useless in our future, personal lives. Instead, we should be inspired to go and learn about the subjects that we are passionate towards, or at least what is related to those passions. For instance, as a student working in the direction of becoming a theatre major, it is not under my impression that it should be mandatory of me to participate in classes that do not involve some type of lessons that will aid my acting career. Here is an example: I’m not going to rely on my knowledge of math or science to pursue a successful profession in theatre. But as an alternative I should become well-informed about many types of literature. The subject of English will be the most helpful to me while going through life as a performer of the arts. Yeats’ description of education reminds me somewhat of another quote from the highly gifted Albert Einstein. Einstein said, â€Å"I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.† (GoodReads, Einstein, www. Goodreads.com/quotes/tag/imagination). Both of them touch on the importance of the free mind, and how some knowledge is not always necessarily needed in life. Now, don’t misunderstand the meanings of these expressions. By no means should knowledge as a whole be absent from your qualities, but your main focus should not be to overflow your mind with knowledge. This topic is very controversial- most people would disagree in a heartbeat. People who disagree have a right to their opinion, but, they must also respect the opposing one too. The way that these theories are worded just provokes close-minded people to argument. But, if they were to try and un derstand the importance of what your imagination can teach you, they may change their minds. From my personal standpoint, by practicing the art of imagination, and by allowing my mind chase its dreams, I have fueled a spark in myself that has lit a fire. This fire is why I burn to be educated about the performing arts and all of the beautiful things I learn about myself while doing so. I have learned more and more about myself every day that I let my imagination educate me. My experiences at school have never come close to revealing the amount of truth in learning as my minds eye has. Einstein also said, â€Å"Education is what remains after one has forgotten what one has learned in school.† (Albert Einstein, brainyquote.com) Therefore, it is what we take away from our education that shows what we have really learned. These are the things we will apply in our lives. We will prosper through the things we enjoy, and forget the useless information. Though to say what information is useless is entirely up to each individual. Also, as time passes we may change our minds as to what is useful to us or not, but that is the beauty of being able to change our minds and educate ourselves about whatever makes us happy. It is passion that drives us, and passion that will truly educate us. â€Å"Develop a passion for learning. If you do, you will never cease to grow.† (Anthony J. D’Angelo, quotationsbook.com/quote) If you are to take anything away from these words let it be this: Have a desire to learn, and be passionate about your education.

Nanotechnologys Impact on the Field of Catalysis

Nanotechnologys Impact on the Field of Catalysis   Mohammed Yusuf What is Nanocatalysis? The word Nanocatalysis is made up of two parts, nano and catalysis. Lets begin my tackling the first part. Nano, short for nanotechnology, is the study of extremely small things, and their applications to society. 1 nanometre is a billionth of a meter (Nano.gov, 2016). And as for catalysis, this refers to a chemical reaction bought about by a catalyst, with a catalyst being a substance that makes it possible for a reaction to be faster, by matching chemicals together quicker (Northwestern, 1999).   Nanotechnology and catalysis go together so well because in order for a catalyst to be as good as possible, it needs to have a large surface area. This allows the catalyst to interact with as much of the reactants as possible. Why I am researching Nanocatalysis? I decided to pursue this topic because the entire chemical industry is dominated by catalysts, nearly every product created via chemical reactions has been produced with the help of a catalyst. Furthermore, I chose this topic because of its futurology aspect its a well-known fact that global warming is slowly destroying our habitat, Earth. According to NASA, the carbon dioxide levels are the highest they have ever been in 650,000 years. This is contributing to the fact that our global temperature is up 1.4o F since 1880 (climate.nasa.gov, 2016). However, the scientists of this world arent just accepting this as our collective future, nanotechnology being used for catalysis has reinvented catalyst designing, and now catalysts can be designed to absorb harmful chemicals and gases that contribute to global warming. Because of nanotechnology, catalyst membranes can be modified to remove unwanted molecules from liquids and gases through the membrane design. (Nanowerk, 2010) What will this report be about?   Ã‚   This report will look into how nanotechnology is reinventing catalysis, Nanocatalysis real world applications, how it could be used to combat global warming, how Nanocatalysis is saving money and   how it is a safe alternative to ordinary catalyst. However, we will also dive into the problems that face the industry of Nanocatalysis, how it could pose health and safety issues to humans and how nanotechnology is very difficult to control. Efficiency: There are two types of catalysts, Heterogeneous and Homogenous. Heterogeneous catalysts are in different phases to the reactants, they are solid while the reactants are liquid. However Homogeneous catalysts are in the same phase as the reactants, if they are liquid, gas or solid so are the reactants. The key objective to making nanocatalysts work is making them as efficient as possible, stabilizing catalysts has been an issue for a very long time you need the catalyst to have a long lifetime, with a very high selectivity (more desired products formed). According toP. Nagaraju Rao, A good stabilizer is one that protects the nanoparticles during the catalytic process, but does not neutralize the surface of nanoparticles resulting in loss of catalytic activity. Catalyst stabilizers come in many forms, from metals to polymers. To increase efficiency as much as possible, scientists have used nanotechnology to create nanocatalysts supports. Through the discovery of a porous aluminium oxide powder, scientists have been able to improve efficiency. Dr Brian Woodfield and David Selck have used this porous material, with its huge network of pores, each 3 nanometres in length, and have filled each pore with expensive catalytic metals each pore 30,000 times smaller than a human hair. This may sound expensive, purchasing platinum and using it to fill holes, but it is on such a small scale that it is saving a huge amount of money. So, in theory, you are using less metal but each tiny piece of metal adds up to produce a huge surface area. In industry, clumps of platinum used to be used which is outrageous. Since it is a known fact that only the atoms on the surface that are exposed to the reaction are useful, this type of nanocatalysts saves so much time, money and effort. Dr Brian Woodfield and David Selck are wor king on producing tiny 1 nanometre crystals of these expensive metals and placing them in porous aluminium oxide, so every atom in the metal is being used. This streamlines production and therefore it improves efficiency. (Cougar Cosmos, 2011)[DS1] Improving reaction yield: Nanocatalysts are more efficient than normal catalysts, as I have established. This major advantage leads to a higher yield of the desired product in a chemical reaction. A real world example of this would be the production of biodiesel from waste cooking oil, where the Solid acid nanocatalysis of Al0.9H0.3PW12O40 nanotubes with double acid sites yield 96% of biodiesel from waste cooking oil as compared to 42.6% with conventional H3PW12O40 catalyst.   (P. Nagaraju Rao, 2010) Absorbing harmful gas emissions: By controlling the pore size of the catalytic membranes in nanocatalysts, you can alter them to remove unwanted molecules, such as harmful gases such as CO2 (global warming) and NO2 (ozone depletion), (Nanowerk, 2016). And through further experimentation by chemical engineers, leading nanotechnology research company Oxonica have produced a nano-diesel fuel additive which decreases fuel consumption, greenhouse gas emissions and other harmful emissions. This rock solid research has gone through years of large-scale trials. The science behind this is truly staggering through the utilization of Cerium oxide nanoparticles in the early stages of combustion, the peak pressure of reaction is reduced. This has a knock on effect, because this reduced pressure results in less NOx emission. This prolongs combustion, which leads to a reduction in inburnt hydrocarbon and, ultimately, a decrease in fuel consumption of up to 9%. This research can be applied to nanocatalysts, the genius of the resea rchers behind this discovery used fundamental physics knowledge to manufacture a product that makes the engine do more work for the same fuel used which can be also be done with catalysts! (P. Nagaraju Rao, 2010) Global warming is a very pressing issue, with the 10 warmest years ever recorded being logged since 1997 its these small improvements in existing reactions that add up to something phenomenal. (Friends of the Earth briefing, 2010) Karine Philippot and Philippe Sers research paper into the concepts of nanocatalysis perfectly outlines the benefits of nanocatalysts, as opposed to normal catalysts. Figure 1. (Karine Philippot and Philippe Ser, 2013) Shows us how nanomaterials are more efficient than regular materials. Figure 2. (Karine Philippot and Philippe Ser, 2013) Shows us how smaller particles (nanocatalysts) have higher selectivity than larger particles. Figure 3. (Karine Philippot and Philippe Ser, 2013) Shows how nanocatalysts have larger surface area than traditional catalysts. Lack of support from investors: Although the future for nanocatalysts look bright, it needs funding and support from investors to kick off and dominate the chemical industry. Investors are not heavily investing in research of newer types of catalysts. Instead, they are only investing in commercially approved nanocatalysts such as industrial enzymes. This is very worrying, as research into newer types of nanocatalysts is vital for this field to continue to improve. This wont happen if well-established nanocatalysts continue to receive the lions share of funding and investment. Lack of support from market: Funding may be vital, but so is good commercial performance. Newer nanocatalysts have a hard time finding buyers, as corporations continue to buy commercially well-established nanocatalysts. Commercially well-established nanocatalysts such as zeolites take up 98% of all global sales, which is a staggering figure. Hopefully, through more academic research companies will begin to venture into newer forms of nanocatalysts. (P. Nagaraju Rao, 2010) The market will eventually embrace nanocatalysis: Global Industry Analysts, Inc. predict that nanocatalysis will receive huge interest in the future, as global warming becomes more apparent and companies are either forced to, or willingly embrace more environmentally friendly methods. The global market for nanocatalysts is expected to reach $7.2 billion by 2020 with nanocatalysts focused on removing harmful greenhouse gasses receiving the most attention. The strength growth of automobile production in India and China means the Asia-Pacific will emerge as the fastest growing market. They believe automobile production will be a huge revenue stream for this global market as nano-catalytic converters will be become the new norm for the automobile industry. This makes sense, with the astonishing rise of the electric car, fuel based cars will eventually be phased out of society due to global warming concerns nano-catalytic converters can add a breath of life to this dying business. (Strategyr.com. 2015[DS2]) Furthermore, Global Industry Analysts, Inc. also point to the growing focus on reducing emissions in coal-fired power plants, stringent emission control norms and increasing adoption in waste water treatment. Figure 4. (Global Industry Analysts Inc. 2016.) Nanocatalysts vs catalysts: Normal, expensive metal, catalysts have been used for a very long time this doesnt truly mean they are better. Lets take platinum as an example, which suffers from low efficiency, slow kinetics, high costs and a very short lifetime. Nanocatalysts are efficient, save money, durable and have a high stability. They are essentially the new generation of catalysts. But that doesnt mean that the old will be phased out. As Ive discussed previously, engineers and material scientists such as Dr Brian Woodfield and David Selck are using highly expensive metals such as platinum and putting them in porous nanocatalysts supports to the point where so little of the expensive metal is being used, that the actual cost is reduced extensively. (Karine Philippot and Philippe Ser, 2013) Therefore, it would be better to classify nanocatalysis as an evolution, drawing from the old norms of chemistry and material science and using the theory behind this to reinvent the standard. Through secondary research, I was able to gather information from a large number of sources. At the start of this research, I had many goals and vague ideas about what nanocatalysis had the potential to be. Through extensive research I was able to establish that nanocatalysts will be essential to solving large scale issues such as global warming by transitioning the world from large emissions of greenhouse gases to low emissions of these harmful gases. This will have huge effects on the world, with deals such as the Paris Climate Agreement put in place to ensure global warming isnt the end of the world, nanocatalysis will surely be a card government and corporations will be playing. I was also able to establish, through my research, that nanocatalysis is soon to be a very lucrative industry. Industrial predictions show that since nanocatalysts save money, improve efficiency, selectivity and yield it will grow to be a $7.2 billion dollar global market to put this into perspective, this is more than double the valuation of the Cyprus stock exchange.

Eating Disorders Essay -- Anorexia Bulimia

Eating Disorders Eating disorders are sweeping this country and are rampant on junior high, high school, and college campuses. These disorders are often referred to as the Deadly Diet, but are often known by their more popular names: anorexia or bulimia. They affect more than 20% of females between the age of thirteen and forty. It is very rare for a young female not to know of someone with an eating disorder. Statistics show that at least one in five young women have a serious problem with eating and weight (Bruch, 25). The Deadly Diet appears to be a mostly female problem. Eating disorders are most common in the middle to upper middle class families. Currently, the incidence is much lower in females from the â€Å"blue collar† families. The Deadly Diet can begin anywhere from the ages of ten to thirty. The peak age for the beginning of the Deadly Diet in females is eleven to fifteen; the peak for males is between fifteen and eighteen (Bauer, 89). Most of the information on the Deadly Diet says that it is a problem of teenage girls, but as clinics have found, most of the people who come to get therapy are in their twenties and thirties. This may be because younger people are less likely to seek professional help. Most often it is the parent who brings the patient for help. Adults who have left home and had to deal with managing their lives usually tend to realize more clearly the need to seek help and make changes. Everywhere one looks today, one will notice that our culture places a very high value on women being thin. Many will argue that today’s fashion models have â€Å"filled out† compared to the times past; however the evidence of this is really hard to see. Our society admires men for what they accomplish and what they achieve. Women are usually evaluated by and accepted for how they look, regardless of what they do. A woman can be incredibly successful and still find that her beauty or lack of it will have more to do with her acceptance than what she is able to accomplish. â€Å"From the time they are tiny children, most females are taught that beauty is the supreme objective in life† (Claude-Pierre, p18). The peer pressure for girls in school to be skinny is often far greater than for boys to make a team. When it is spring, young girls begin thinking â€Å"How am I going to look in my bathing suit? I better take off a few more pounds.† Another reason t... ...than men, our society is evolving. Men can act more sensitively. â€Å"We are finally a more humanistic culture rather than a culture of warriors.† (Claude-Pierre, p.70) Eating disorders among men are on the rise-at least one million men number among the eight million people who suffer from them in the United States. The Deadly Diet affects many people, but it can be cured. Works Cited Ardell, Maureen and Corry-Ann Ardell. Portrait of an Anorexic; A Mother Daughter’s Story.

How to Calculate the G Forces in NHRA Drag Racing :: Process Essays

How to Calculate the G Forces in NHRA Drag Racing In the sport of professional drag racing gravity takes on an entirely different meaning while accelerating these monsters down the track at speeds in excess of 330 miles per hour. The force exerted on the driver is known as G force. In this short journey down the track, the formula to calculate the forces exerted on the driver will be demonstrated. Next the forces exerted on the driver in the individual classes of cars. Then at the end of the quarter mile G force rears its ugly head again when the parachute is deployed to bring the monsters from their maximum speeds to a stop. In the end does this have an effect on the human body? To calculate the average acceleration will be derived by converting miles per hour into meters per second. To do this, divide the miles per hour by .6. This will give kilometers per hour. Then multiply that by 1000. This will give meters per hour. This gives meters per hour, to convert this to meters per second divide meters per hour by 3600. At this point divide by the time of the run, this is the average acceleration. Next it is known that gravity makes things fall at a speed of 10 meters per second. Take the average acceleration divided by the time to complete the run and divide this total by 10 meters per second and this gives a number that represents a multiple of gravitational force exerted on the masses involved in the acceleration. This number is a multiple of the normal gravitational force exerted on everything on earth. If the racer weighs 190 pounds and experiences 2.5 G’s their body would feel as if it weighed 475 pounds. This causes a big strain on the body. The exact physical response on the human is not exactly known because studys on pilots show that some can become accustomed to a little higher G force as when they first started the study. Over all it showed that a human would loose consciousness between 8 and 9 G’s. the space shuttle launches at about 3 G’s. Modern fighter jets pulling out of a hard dive can experience about 8 G’s. Under this kind force the blood pools in, usually the wrong, parts of the body. However, the human body can withstand high G’s for very brief periods of time.

performing arts Essay -- essays research papers fc

What is Performance Art? How does it differ from Theater? The term "Performance Art" started in the United States in the 60's. It was originally used to describe any live artistic event, which included poets, filmmakers, musicians, dancers, etc. Even though the descriptive word came about in the 1960's, there were earlier precedents for performance art. The live performances of the Dadaist meshed poetry and visual arts. The German Bauhaus, founded in 1919, included theater workshops that explored the relationship between space, sound and light. Direct influence also came about later in the 50's on through the 60's with the Beatniks and the happenings that took place in the Lower East Village in NYC. Earlier movements such as the Italian Futurists were also very involved in paving the way for what was to come in the 70’s. By 1970 the term, performance art was used globally and specifically defined as live art, not theater. Even though theater and performance art often times share the same stage, in practice they are very different. Performance art is not a form of representational art, rather a moment of acquiring multiple characters and creating a fusion between one and the next, but never allowing the true self to ever fully disappear. A performer of performance art is usually oneself either telling a story, a feeling, an opinion, whether it be through video, movement, music, television, poetry, sculpture, spoken dialogue or any mix of these. An actor usually is personifying someone else under very specific conditions. Performance art leaves more leeway for improvisational efforts to factor whether it is text based or strictly movement. The script is a security paper reassuring a certain aspect of structure, but does not hold an absolute strict compromise. No two performances are ever really al ike. A script for an actor is a bible; it tells how and when an action will happen. All cues, lines and characterization get memorized and obsessively rehearsed so that every time performed an almost identical performance is released. Rehearsals for performance artists are much more conceptual and often times will include researching, gathering props and costumes and having discussions with collaborators in their rehearsal time.

It allows the artist to be an insider and outsider at the same time, crossing the border of points of view at all times. It functions on different levels of society’s social structure, sometimes right on par with current events and other times defying all common everyday needs and resistance. Performance art fluctuates between boundaries of all art. Its conceptual territory lies within the contradiction, the ambiguity and the extreme, making it difficult to define borders. Performance art is a means of art that cannot be bought or sold. It is a chance where all art forms converge in many different mixes, whether it be music, video, painting, poetry, movement, etc. In a postmodern society where all genres loose their limits and are hard to define, performance art has become an absolutely hybrid art form.

ANS: A! A sedentary lifestyle contributes to the development of health-related problems.A holistic approach is taken to develop overall fitness and includes warm-ups, aerobic ex ercise, resistance training, weight training, and so forth. The recommended frequency of aerobic exercise is 3 to 5 times per week or every other day for approximately 30 minutes. Crosstraining is recommended for the patient who prefers to exercise every day. Some patients use weight training to bulk up their muscles.

ANS: B! Assessing range of motion is one assessment technique used to determine the degree of damage or injury to a joint. Gait is the manner or style of walking. It may have little bearing on the shoulder damage. Assessing fine motor coordination would be beneficial in helping to assess the patient’s ability to perform tasks but would not help in evaluating the shoulder.

Fatigue related to poor physical condition! b.! Impaired gas exchange related to decreased cardiac output! c.! Decreased cardiac output related to decreased myocardial contractility! d.! Activity intolerance related to physical deconditioning! ! !! ANS: D! When activity and exercise are problems for a patient, nursing diagnoses often focus on the individual’s ability to move. The diagnostic label directs nursing interventions.In this case, physical deconditioning must be addressed relative to activity level, perhaps leading to 6-minute walks twice a day. Physical deconditioning is the cause of fatigue as well, so it would take priority over that diagnosis. Decreased cardiac output and myocardial contractility ar e serious concerns that must be addressed before activity intolerance to keep the patient safe and to help determine the level of exercise that the patient can tolerate, but reconditioning of the patient’s body will help improve contractility and cardiac output.! !!

The diagnostic label directs nursing interventions. This requires the correct selection of related factors. For example, Activity intolerance related to excess weight gain requires very different interventions than if the related factor is prolonged bed rest. In this case, the intolerance is related to the patient’s excessive weight. He is not on bed rest, although he claims that it is difficult for him to get out of bed.Shortness of breath is a symptom, not a cause, of Impaired gas exchange, making this nursing diagnosis ineffective.
