The Law of Conservation of Energy Defined

The Law of Conservation of Energy Defined The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another. Another way of stating this law of chemistry is to say the total energy of an isolated system remains constant or is conserved within a given frame of reference. In classical mechanics, conservation of mass and conversation of energy are considered to be two separate laws. However, in special relativity, matter may be converted into energy and vice versa, according to the famous equation E mc2. Thus, its more appropriate to say mass-energy is conserved. Example of Conservation of Energy If a stick of dynamite explodes, for example, the chemical energy contained within the dynamite changes into kinetic energy, heat, and light. If all this energy is added together, it will equal the starting chemical energy value. Consequence of Conservation of Energy One interesting consequence of the law of conservation of energy is that it means perpetual motion machines of the first kind are not possible. In other words, a system must have an external power supply to continuously deliver unlimited energy to its surroundings. Its also worth noting that its not always possible to define conservation of energy because not all systems have time translation symmetry. For example, conservation of energy may not be defined for time crystals or for curved space times.

The Utilitarian Art of the Mesolithic Age

The Utilitarian Art of the Mesolithic Age Otherwise known as Middle Stone Age, the Mesolithic Age covered a brief span of around 2,000 years. While it served as an important bridge between the Upper Paleolithic and Neolithic Ages, the art of this period was, well, sort of boring. From this distance, its not nearly as fascinating as the discovery of (and innovations in) the art of the preceding era. And the art of the subsequent Neolithic era is exponentially diverse, besides being more well-preserved and offering us thousands of examples of itself, instead of a handful. Still, lets briefly cover the artistic events of the Mesolithic Age because, after all, its a distinct era from any other. Animal Husbandry During this period, most of the glacial ice in the Northern Hemisphere had retreated, leaving behind geography and climates familiar to us in the present day. Along with the glaciers, certain foods disappeared (the wooly mammoth, for example) and the migration patterns of others (reindeer) changed as well. People gradually adapted, assisted by the facts that more temperate weather and diverse edible plants were there to aid in survival. Since humans didnt have to live in caves or follow herds any longer, this era saw the beginnings of both settled communities and farming. The Mesolithic Age also saw the invention of the bow and arrow, pottery for food storage and the domestication of a few animals- either for food or, in the case of dogs, for help in the hunting of food. MesolithicArt Pottery was beginning to be produced at this time, though it was mostly utilitarian in design. In other words, a pot just needed to hold water or grain, not necessarily exist as a feast for the eyes. The artistic designs were mainly left up to later peoples to create. The portable statuary of the Upper Paleolithic was largely absent during the Mesolithic Age. This is likely a result of people settling down and no longer requiring art that could travel. Since the invention of the arrow had occurred, much of this periods carving time seems to have been spent knapping flint, obsidian and other minerals which lent themselves to sharp, pointy tips. The most interesting Mesolithic Age art that we know of consists of rock paintings. Similar in nature to the Paleolithic cave paintings, these moved out of doors to vertical cliffs or walls of natural rock, often semi-protected by outcroppings or overhangs. Though these rock paintings have been found in locations ranging from the far north in Europe to southern Africa, as well as elsewhere around the globe, the largest concentration of them exists in eastern Spains Levant. While no one can say with certainty, the theory exists that the paintings locations werent chosen at random. The spots may have held sacred, magical or religious significance. Very often, a rock painting exists within close proximity to a different, more suitable spot upon which to paint. Characteristics of Mesolithic Art Between the Upper Paleolithic and Mesolithic eras, the biggest shift in painting occurred in the subject matter. Where cave paintings overwhelmingly depicted animals, rock paintings were usually of human groupings. The painted humans typically seem to be engaged in either hunting or rituals whose purposes have been lost to time. Far from being realistic, the humans shown in rock painting are highly stylized, rather like glorified stick figures. These humans look more like pictographs than pictures, and some historians feel they represent the primitive beginnings of writing (i.e.: hieroglyphs). Very often the groupings of figures are painted in repetitive patterns, which results in a nice sense of rhythm (even if were not sure what theyre meant to be doing, exactly).

Project Management - Essay Example Measurement and accountability; check if the task has been a winner and if it has maintained all through. This is done by holding meetings and interviewing the leaders of their respective projects (Ganon, 2004). With the scope first, identify the project schedule and time management in which the project manager should come up with a realistic plan and its efficient management and define the time frame for completion of the project. Secondly, a real project is identified within the specified budget. Thirdly, procurement should be in place. Fourthly, consider the project quality. Fifthly, the project team should be looked at ensuring the project has the right skills, at the right place and the right duration to ensure there is the smoothness in the whole project time. Sixthly, ensure there is proper and prompt communication among the project players. Finally, identify the uncertainties. What are the possible causes of risks in that project, what is their possibility of occurrence and their severity, and what measures can we take to mitigate them ( Patel, 2008). Gantt charts and Critical paths help apparently spot where resources need to be anticipated and apportion them. The Gantt helps to ensure the project is within the budget constraint, a thing Mrs. Penny never took into consideration making the project to lose hundreds of thousands of dollars. They also assist the team players to be on the same page as there is a visual framework of the work to be done. Chances of confusion and misunderstanding are minimized as all the stakeholders hold the same data. The Gantt chart also helps in undertaking the task relationship among the project team. The table helps in identifying how various works are interrelated towards achieving the objective of the project. If Penny Black could have plotted the activities of the different functions carried

Of mice and men by John Steinbeck Essay Example for Free

Of mice and men by John Steinbeck Essay Studying stage Drama enables us to see into a world that is very different from our own and to feel compassion for those who are unable to take control of their own lives Of mice and men By John Steinbeck is a very interesting and compelling text, and positions us as the reader to accept Lennie as the victim even though he killed someone, we as the reader are given many insights that some of the other characters do not get to experience, and therefore can get this message as the dominant reading. The earliest accounts of the life of Lennie and George tells us a tale about Lennie and his accidents involving mice, Lennie who gets presents of mice from his aunt, crushes there heads, because he doesnt know his own strength, he loves the mice, and cared for them, but because of his love for the mice they bite him and he crushes the mouses heads, Lennie is definitely mentally retarded, and as such he does things that regular people would not do it would seem that Lennies mentality was not designed for his body, if he was a thin weedy man then he would have no problems, he could pet animals AND make them stay alive, but things arent always as we like them Because the playwright is trying to establish Lennie as the good guy we are also positioned at the scene of their last job, Lennie feels a ladies dress, the woman screams, he holds on, she starts yelling to the police, he holds, and as a result, poor George has to spend a night in a ditch and what was the reason? I only did it to feel how soft it was says Lennie, even though this is still fairly strange, you as the reader can relate to him and say well, it really isnt his fault. Now I know you are wondering, Why did Lennie hold on even through the screams and the yelling police, why didnt he just let go? consider this story, a young child between the ages of 1 and 3 is found near his dead mother, holding on for dear life, and mentally Lennie was much the same way whenever he gets scared or frightened, he will hold on to it, you cannot blame the woman for her reaction, a big tall man grabbing onto her dress, she has every right to feel threatened, and as a result, Lennie gets George into trouble, and they have to spend the night in the ditch. On the farm, curly is picking fights; not only is he picking fights but he is picking fights that he cant win, apart from his height, what exactly did Lennie do? He laughed, oh no, dear God, how will he survive? George was going to teach him a lesson, but he wanted Lennie, this time he went too far, Lennie didnt want to fight curly, but he gave him no choice, he was scared and frightened, and once again, the mentality issue shines brightly, he grabs Curlys hand and he doesnt let go, he crushes every single bone in his hand, and again Lennie is portrayed as the good guy, what else could he do? The final matter is the matter of Curlys wifes death, this even if he is retarded, still classifies as murder, no matter how much they try to sugar coat it, it is still murder, and he pays for it with his own death, he gave George, his best friend, no other choice other than to kill him for his own good, his strength, has been the cause of all these problems right from the beginning, and although you can feel sorry for him, he should have had more common sense, he was retarded, and there is nothing you can do about that, but he should have learnt what was right and appropriate, and killing innocent people, even if it was manslaughter, is still bad. And so we are given an insight into the life of Lennie, we feel compassion for him and George, we have been positioned to draw this conclusion, well, youd be hard pressed to try and prove he wasnt wouldnt you? It seams there is two cases of murder (not counting the various animal deaths) George isnt the bad guy because he did what was best for Lennie, and Lennie wasnt the bad guy because he is retarded.

Teaching Philosophy :: Education Teachers Classroom Essays

Teaching Philosophy Teachers are the sculptors of every child’s future. No other job comes with the satisfaction of knowing that you have made at least the slightest difference in a child’s life. Little things that you say and do will always be remembered. Not only will you be a teacher but you will also play the role as, a friend, mentor, hero, and many others. As a teacher I plan to run my classroom with rules and consequences, but my students will realize that they are treated fairly. They will have a voice and say so concerning what goes on in the classroom. Seating arrangements will depend on classroom instructional activities. There will be lots of group activities, since most kindergarteners aren’t used to being around children their own age. The room will be bright and very colorful to keep their senses alert. My bulletin boards will display the calendar, colors, numbers, and the alphabet. They will include people from all cultures on them. I will have learning centers around the room that the students will be able to go to in their free time. These centers will teach the students to tie their shoes, button their clothes, cut out shapes, color in the lines, and other supplementary skills. My classroom will be run in a democratic fashion, which is pragmatism. The students will have lots of say so over the rules and the way the classroom is run. It will be child centered since the students will be the most important part of the classroom. They will have a voice and say so concerning what goes on in the classro om. These are examples of how I will use the existentialism philosophy. I will be a guide in the learning process of my students. I would establish a non-authoritarian classroom. I want my students to see me as their instructor, not their boss or authority figure. I will run a facilitating classroom with circle seating arrangements, student centered activities, problem solving, and reciprocal teaching. I feel as if I am a pragmatist and I will use the theory or progressivism to run my classroom.

Food Macromolecules

â€Å"Macromolecules are a source of fuel. There are four major types of macromolecules-proteins, carbohydrates, nucleic acids, and lipids. This process plays important roles in the life of a cell. (Macromolecules, 2002). The macromolecules that was present in the packaged food product Lipids which are fats. According to (Alters & Alters 2009, p. 49) Fats also provide more energy in our diets that do equivalent amounts of carbohydrates or protein. Protein was also present on the packaged food. Proteins transport and rovide muscle contraction. Alters & Alters 2009, p. 51) Proteins build, maintains, and replaces the tissue in our body. Tissue meaning: muscles, organs, and your immune system. They are also important for the movement of lungs, legs, and protecting you from disease. (Learning about proteins,2008). How much protein do we need each day? Adults should get a minimum of 0. 8 grams of protein for every kilogram of body weight per day. Increasing protein intake helps reduce the risk of heart disease. (The Nutrition Source: Protein, 2011). Carbohydrates are also present in the packaged food. Carbohydrates provide the body with fuel for physical activity and proper organ function. The best sources of carbohydrates -whole grains, vegetables, fruits, and beans- promote good health. (The Nutrition Source: Carbohydrates, 2011) Lipids are also present in the packaged food. Lipids are a group of molecules that consist of fats, phospholipids, and cholesterol. This packaged food is a part of a heart healthy diet because it has carbohydrates, low saturated fats, and proteins. Carbohydrates are important for fuel, breaking these bonds and releasing energy to sustain life (Alters & Alters, 2009, p. 47). Large amounts of saturated fats may lead to clogged arteries and risk of heart disease. (Alters & Alters, 2009, p. 50). The product I have chosen to use is Quaker Oatmeal. I consider carbohydrates to be the most important thing listed on the label. Knowing the amount of carbohydrates is important because carbohydrates turn into sugar, and there is only one gram of sugar in this product. When carbohydrates turn into ugar this increases the risk of diabetes if there is to much carbohydrates in your diet. I have never been a health fanatic, but after doing this essay I need to be a little cautious of what I am eating. I have found that reading labels helps us to eat healthier and to make the right choices our life style. I never really understood how carbohydrates work. Now I know the understanding of good and bad carbohydrates. Heart disease runs in my family. I do have a healthy heart but after doing the research for this essay I hope to continue to stay healthy.

How New Technology Has Brought About The Changes In The Bank essays

How New Technology Has Brought About The Changes In The Bank essays How New Technology Has Brought About The Changes In The Banking Industry. The new technology has brought rapid changes in the banking industry and financial services. Online banking and electronic payment systems are the new development and diffusion of technology by financial institutions and are expected to result in a more efficient banking system. In addition to the trend of online banks, they have proven to last longer in the banking system. Technology has changed the banking industry because it now offers alternative and better channels through which products and services can be provided to customers. Some examples of the changes in the banking industry are the online banking and access to ATM machine. Online banking is a form of banking that can be done through the use of Internet and can be done at home, work, or wherever there is access to the Network. It allows customers to perform all routine transactions, such as bill payments, electronic transfer, balance inquires, account transfers, investments, and stop payment request. It basically allows the customers to carry out all the transactions just as in a normal bank except withdrawing of cash. This can be done at anytime during the day, and it is less time consuming when compared to waiting in the actual bank building where customers have to wait in long lines. There is hardly any paper work to be done; the customers can carry out transactions from anyplace that has access to the Internet. Once the information has been saved, it doesnt need to be re-entered for similar subsequent checks. Take for example, Virtual Bank, founded in February of 2000, is an entirely online experience, from opening to closing of your accou nt.

Problems for Teachers That Hinder Their Effectiveness

Problems for Teachers That Hinder Their Effectiveness Problems that teachers face include handling student needs, lack of parental support, and even criticism from a public that can be largely unaware of their everyday lives. Addressing these problems and bringing awareness to the educational environment that our teachers and students face daily can help improve teacher retention, student success rates, and the overall quality of education in our schools. Balancing a Wide Range of Student Needs No matter what type of school youre talking about, teachers have to deal with a wide range of student needs, but public schools may struggle the most here. While private schools are able to select their students based on an application and assessment of the best fit for the school and community, public schools in the United States are required to take every student. While most educators would never want to change this fact, some teachers are faced with students who distract the rest of the classroom and add a significant challenge. Part of what makes teaching a challenging career is the diversity of the students. All students are unique in having their own background, needs, and learning styles. Teachers have to be prepared to work with all learning styles in every lesson, requiring more prep time and creativity. However, successfully working through this challenge can be an empowering experience for both students and teachers alike. Lack of Parental Support It can be incredibly frustrating for a teacher when parents don’t support their efforts to educate children. Ideally, a partnership exists between school and home, with both working in tandem to provide the best learning experience for students. However, when parents dont follow through with their responsibilities, it can often have a negative impact on the class. Research has proven that children whose parents make education a high priority and stay consistently involved may be more successful academically. Ensuring that students eat well, get enough sleep, study, complete their homework, and are prepared for the school day are just a few of the basic of the things that parents are expected to do for their children. While many of the best teachers go above and beyond to make up for a lack of parental support, a total team effort from the teachers, parents, and students is the ideal approach. Parents are the most powerful and consistent link between children and school since they are there throughout the child’s life while the teachers will change annually. When a child knows that education is essential and important, it makes a difference. Parents can also work to communicate effectively with the teacher and ensure that their child is successfully completing assignments. However, not every family has the ability to provide the necessary supervision and partnership, and some children are left to figure things out on their own. When faced with poverty, a lack a supervision, stressful and unstable home lives, and even parents who arent present, students have to overcome numerous hurdles to even make it school, never mind succeed. These challenges can lead to students failing and/or dropping out of school. Lack of Proper Funding School finance has a significant impact on teachers ability to maximize their effectiveness. When funding is low, class sizes often increase, which impacts instructional curriculum, supplemental curriculum, technology, and various instructional and extracurricular programs. Enrichment programs are cut, supply budgets are limited, and teachers have to get creative. Most teachers understand that this is completely out of their control, but it doesn’t make the situation any less frustrating. In public schools, finances are usually driven by each individual state’s budget and local property taxes, as well as federal funding and other sources, whereas private schools have private funding and often more flexibility in how it is spent. That means public school teachers are often more affected by lack of funding and are limited in how they can spend their money. In lean times, schools are often forced to make cuts that have a negative impact. Most teachers make do with the resources they are given or supplement with their own personal contributions. Overemphasis on Standardized Testing Not every student learns in the same way, and therefore not every student can accurately demonstrate mastery of educational topics and concepts in a similar fashion. As a result, standardized testing can be an ineffective method of assessment. While some teachers are completely against standardized testing, others tell you that they don’t have a problem with the standardized tests themselves but with how the results are interpreted and used. Most teachers say that you can’t get a true indicator of what any particular student is capable of on a single test on any particular day. Standardized tests arent just a pain for students, either; many school systems use the results to determine the effectiveness of the teachers themselves. This overemphasis has caused many teachers to shift their overall approach to teaching to a focus directly on these tests. This not only takes away from creativity and limits the scope of what is taught but can also quickly create teacher burnout and put excess pressure on the teachers to have their students perform well. Standardized testing brings with it other challenges as well. For example, many authorities outside of education only look at the tests bottom line, which hardly ever tell the whole story. Observers need to take much more into account than the overall score. Consider the example of two high school math teachers. One teaches in an affluent suburban school with lots of resources, and one teaches in an inner-city school with minimal resources. The teacher in the suburban school has 95% of her students score proficient, and the teacher in the inner-city school has 55% of his students score proficient. If only comparing overall scores, the teacher in the suburban school would appear to be the more effective teacher. However, a more in-depth look at the data reveals that only 10% of students in the suburban school had significant growth during the year while 70% of the students in the inner-city school had significant growth. So who is the better teacher? You can’t tell simply from standardized test scores, yet a large majority of decision-makers want to use test scores alone to judge both student and teacher performances. Poor Public Perception Weve all heard the old saying Those who can, do. Those who cant, teach. Unfortunately, a stigma is attached to teachers within the United States. In some countries, public school teachers are highly regarded and revered for the service that they provide. Today, teachers continue to be in the public spotlight because of their direct impact on the nation’s youth. Theres the added challenge that the media often focuses on negative stories dealing with teachers, which pulls attention away from their positive impact. The truth is that most teachers are dedicated educators who are in it for the right reasons and doing a solid job. Focusing on a good teacher’s best qualities can help teachers overcome their perceptions and find fulfillment in their profession. Educational Trends When it comes to learning, experts are always looking for the best tools and tactics for educating children. While many of these trends are actually strong and worthy of implementation, adoption of them within schools can be haphazard. Some believe that public education in the United States is broken, which often drives schools to look at ways to reform, sometimes too rapidly. Teachers can be faced with mandated changes in tools, curriculum, and best practices as administrators race to adopt the latest and greatest trends. However, these constant changes can lead to inconsistency and frustration, making teachers lives more difficult. Adequate training isnt always made available, and many teachers are left to fend for themselves to figure out how to implement whatever has been adopted. On the flip side, some schools are resistant to change, and teachers who are educated about learning trends may not receive funding or support to adopt them. This can lead to a lack of job satisfaction and teacher turnover, and it can hold students back from delving into a new way to learn that may actually help them achieve more.

Leadership discussion broad Essay Example | Topics and Well Written Essays - 250 words - 3

Leadership discussion broad - Essay Example Most companies such as IBM, Capital One has been outsourcing their customer service and backdoor operations to Business Processing Organizations (BPO) already because it is more economical to have them done by third party vendors who has to expertise than for companies to do the operations themselves. Even in the production side of the company, such as the production of the company’s parts that make up its products are outsourced. The classic case for this is Samsung and Apple where parts and accessories of their smartphones and other products are outsourced to third party vendors. They however keep the software and hardware design as well as research and development within the company so as not to give away their strategic advantage and technical competencies. Outsourcing other value creation activities may be cost effective for companies to do but there are also risk involved in it. Outsourcing company operations inadvertently exposes the technical advantage of a firm making it vulnerable to industrial espionage. Another is the case of Apple where it the company is accused of unethical business practice because its third party vendors employed children and use unfair labor practices. This may not be the doing of Apple because it is a reputable company, but the less than desirable labor practices of its third party vendors hurt the company’s
