Blowing in the Wind Essays

Blowing in the Wind Essays Blowing in the Wind Paper Blowing in the Wind Paper Is The Answer: Blowing in the Wind? With the figure of people turning daily, the usage of electricity is on the addition. The Earth will run out of the supply of fossil fuels, if this uneconomical usage continues. The modern comfortss as ovens, air conditioners, visible radiations, etc. all use electricity. We need to look for other beginnings of energy. The other beginnings could be solar, atomic, H2O, and air current power. The 1 that does nt consume itself is wind power. No affair how much air current that is used, there is ever wind left for tomorrow. The good thing about air current is that it is free. As we face the energy jobs of tomorrow, we need to retrieve the words of Bob Dylan`s vocal: Is The Answer: Blowing in the Wind? When you are outside and the air current is blowing, you can experience it. Wind will mess your hair, blow things into you, and if difficult adequate knock you down. You can`t wing a kite or sail your boat without air current. Wind can work for you by utilizing the kinetic energy it produces to pump H2O or do electrical power. Wind moves across the surface of the Earth. A hurricane can bring forth really strong air current and at other times a soft zephyr will rustle the foliages. The Sun plays an of import portion in bring forthing air current by the uneven warming of the Earth. Warm air rises and colder air replaces it. This is called circulation and the air current is the air traveling. Sometimes there are big countries of air current, and certain provinces are more blowy than others. Examples of blowy provinces are California, Texas, and Oklahoma. Peoples have been utilizing the air current to make work for centuries. Mechanical energy or electrical energy is made from the wind`s kinetic energy. Wind can force a boat when the canvass are up. Farmers have used the air current to crunch their maize and wheat by turning crunching rocks, which works like a H2O wheel. Windmills have been around for centuries and used to pump H2O from Wellss. Windmills were used in Holland to travel H2O from low lying countr ies. The air current has been used for old ages, and now more and more it is used to do electricity. Air traveling over the Earth produces air current power energy. In rural countries the windmill was replaced by electricity brought in by power lines. The air current turbines became more popular in the 1970s when used to replace the more expensive electricity. In the `80s and `90s when the environment became more of import the turbine was seen as an good energy beginning that did non damage the environment. Wind energy is converted into mechanical energy by utilizing a air current turbine. When used to pump H2O or as a crunching rock the machine is called a windmill. If the power is changed into electricity, the machine is a air current turbine or a air current generator. The â€Å"upwind† air current turbine has three blades the faces into the air current. Another common air current turbine is the two-bladed or lee turbine. Wind turbines make electricity by working antonym of a fan. A air current turbine uses air current to do power, but a fan uses electricity to do air current. The shaft of the turbine connects to a generator, and as the air current turns the blades electricity is produced. Large turbines range in size from 50 to 70 kWs, while little turbines that are used for places or H2O pumping produce below 50 kWs. Horizontal axis and perpendicular axis are the two general types of air current turbines. The differences in these turbines is: the perpendicular axis has blades that rotate perpendular to the land, and a horizontal axis blades` rotate analogue to the land. The most common air current turbine is the horizontal axis design, but the perpendicular axis turbine has been around for centuries. The perpendicular axis turbine does non roll up energy from the air current every bit good. The rotor or propellor with blades is used to acquire the energy from the air current in a air current turbine. The chief thrust shaft has a hub connected to it with the rotor attached. The generator is in the thrust shaft and that produces the electricity. Plastic, fibreglass, or epoxy covered wood are used to do the blades. Energy Quest- Drawing of Turbine Wind power because of the clean nature and environmental friendliness has ever been popular. Some people feel that air current power is better than solar power, because it keeps working after the Sun goes down. Weave power at times will be plenty and other power will non be needed, besides wind power is free. The high cost of air current turbines and holding to happen the right location are the major ailments about air current power. Wind systems are complicated and non easy to put in. They require regular care and replacing parts. Battery battalions are expensive and frequently have to be replaced. The unpredictable nature of energy production is the chief disadvantage of air current power. Reasonably strong air currents are required to hold the full usage of a air current power system. If the air current dies down the production of energy will diminish.

The fonts that make you remember more - Emphasis

The fonts that make you remember more The fonts that make you remember more We are more likely to remember information when it is written in a hard-to-read font, according to psychologists at Princeton and Indiana universities. Researcher Connor Diemand-Yauman and his colleagues wanted to explore how fonts affect how much we remember from the text we read. They found that learning materials set in slightly harder-to-read fonts produced significantly higher scores in students’ assignments. Arial vs Comic Sans The researchers presented 28 participants with information about three species of aliens, and gave them 90 seconds to learn the features that identified them. For half the participants, the information was presented in clear 16-point, black Arial font. Information for the remaining participants was presented in Comic Sans or Bodoni fonts, both in grey and 12-point. Participants were later tested on the identifying features of the alien species. Those who had learnt from the harder-to-read fonts answered 86.5 per cent of questions correctly, compared with 72.8 per cent by those who learnt from the easy-to-read fonts. The researchers replicated the findings in a similar study at a school in Chesterland, Ohio. Levels of processing So why did the participants remember more about the harder-to-read samples? Diemand-Yauman suggests that when we find something easy to read, we tend to take it as a sign that we already have mastery of the material. But when fonts make reading slightly harder, we often doubt whether we instantly ‘get’ it. As a result, we are more likely to go over the information again to make sure we fully understand it. This encourages deeper processing in the brain, which makes us remember more about the text. But that doesnt mean you use Cloister Black for your reports from now on. Improving readability One of the main challenges of writing is producing a document that people actually read. The participants in the studies above were more likely to read than normal. This is because text was given to them by people in authoritative positions (psychologists, teachers) and in test conditions. But your report isn’t an experiment. And your target audience may not feel obliged to read your piece at all, especially if it’s that little bit harder to read, or it’s set in an inappropriate font. Besides, there’s more to business writing than getting people to remember the details in your documents. It is about setting a good impression too. Much like wearing a suit, your clients will judge your written output on presentation, and one way to get this right is to use the best fonts. Serif vs sans serif fonts Serif fonts are those with the twiddly strokes at the ends of characters (eg Times New Roman, Minion). There is an argument that serif fonts are more distinctive than sans serif fonts (without strokes, eg Arial, Calibri), and are therefore easier to read. However, there are plenty more studies that show there is no difference between them in terms of legibility. Interaction designer Alex Poole thinks most mainstream typefaces are equally legible. He says, ‘It makes much more sense to argue in favour of serif or sans serif typefaces on aesthetic grounds than on the question of legibility.’ Fonts help to set the tone of your professional identity. For business writing, they need to be formal but approachable; sensible but not staid; and consistent, not erratic. That’s why at Emphasis we prefer Arial, a sans serif font, because it is plain, clear and simple – just the qualities we recommend in writing.
