The current use of fossil fuels as our main energy source has two drawbacks: their inevitable depletion and the pollution associated with combustion. These two drawbacks in addition to the growing concern of global warming has pushed for the development of more sustainable sources of energy, namely solar energy and its derivatives (i.e. wind power). Solar energy is appealing for its potential to meet all our demands, while proving to be a pollution free resource.(Bohn, 2009)
Solar energy originates from the thermonuclear fusion reactions occurring in the sun. Leaving all the byproducts of the reactions behind in the sun, the energy that reaches the Earth is pure radiant energy. This energy represents the entire electromagnetic spectrum, ranging from x-rays to radio waves. Most of the sun’s energy, forty-three percent, is in the form of visible light, which can be harnessed for electrical production. The amount of energy hitting the Earth is incredibly large; by one calculation, a month of sunshine has the equivalent energy of all the planet’s used and unused fossil fuels.(Huang, 2007) However, the nature of solar energy has two disadvantages. The sun does not shine consistently throughout the day due to clouds and other atmospheric factors, which can be problem for constant electricity and heat production. Moreover, solar energy cannot be used for nighttime production. The other shortcoming is that the energy from the sun is a diffuse source, that is, it falls over a wide area. In order to utilize this energy, it must be concentrated into a form and amount we can use, such as heat and electricity. These problems are addressed in the three steps used to harness the sun’s energy: collection, conversion, and stor...

Inevitability at one point in most of our lives we have to deal with some type of hardship. A lot of us have experienced first hand or known someone who has had the unfortunate experience of dealing with a close friend or family member who becomes abusive and aggressive because of drug or alcohol related problems. My Papa’s waltz is a poem that tells the story of a young boy dealing with an abusive father and a broken home. Despite the initial light atmosphere of the poem Theodore Roethke uses strong and powerful language to convey an underlined meaning to their dance. My Papa's Waltz is a poem of fear, all the more horrible because the boy is terrified and hurt by his father, even in play, yet he clings and hangs to him showing how strong he is despite his age and through his actions he illustrates his love and patience for his troubled father.
Parmenides of Elea once presented the expression ex nihilo nihil fit, which translates to nothing comes from nothing for one of his many theses. The Cosmological Argument, an argument of the posteriori category, meaning that it requires data based on past experiences, argues for the existence of God with this type of expression at its core. By attempting to prove how the universe must be influenced by an independent being that has godlike qualities, cosmological arguments suggest that it is rational to believe in an omnipotent being and its accountability of creating the universe.
This friendly attitude towards the natives did not last long. There was a settlement left on the island of Hispaniola, after the first voyage, called Navidad. The settlers were supposed to be cementing relations and trading with the natives. On the night of November 27, 1493, when Columbus was on his second voyage back to visit this colony, he was met with only silence. All that was found were the ashes of the town and the remains of the settlers bodies (Dor-Ner 206-207).
In 1484, Christopher Columbus attempted to interest King John II of Portugal in his voyage to explore the West. His attempt was a fail, but that did not make him lose his hope. About eight years later he went to King Ferdinand and Queen Isabella of Spain, attempting his service in leading such an extraordinary voyage. After the death of the last Muslim Spain agreed to finance the voyage and named Columbus as the admiral and governor of any lands he should find. In 1492 Columbus received his approval; he started his voyage to explode the west on August 3, 1492. Columbus first landing was in the Bahamas, later he discovered the Northeast coast of Cuba, eastward to the islands of Hispaniola, which now is known as Haiti and Dominican Republic. When discovering the eastward islands of Hispaniola, Columbus lost his flagship name Santa Maria, one of his famous three shi...
To understand the prompt first you have to understand Cristoforo Colombo, known today as Christopher Columbus. You have to to understand the decisions and steps he took also why Spain chose him to represent them and the voyages he led.
Aquinas believes that is it reasonable to believe that something that we cannot demonstrate, but not anything only certain things. Aquinas’ arguments rely heavily on Aristotle, and unlike Anselm another philosopher who argued for the existence of God; Aquinas’ arguments are based on experience. Aquinas put together five different ways that are five separate arguments. This essay is going to go in depth about the second way (argument) that is the argument from efficient causality (cosmological argument) and Paul Edward’s objection against it.
There is an interesting print advertisement found in an issue of Time magazine. It was an advertisement of noise cancelling headphones by Bose. Bose is known to make high quality products for music such as headphones and speakers. In the ad there is a man in a boat wearing Bose headphones who is rowing a boat and is about to go over a waterfall. The waterfall he happens to be going over is Niagra Falls, which is notorious for being very loud. Niagra Falls is a really well known tourist attraction and is probably the most commonly known waterfall in the world. It is a clever way of showing how the headphones cancel out all outside noise. Also in the top right corner there is text that says “Bose Noise Headphones” and an even smaller caption saying “Bose noise reduction kills”. The advertisement uses a real interesting way to show the target audience that by using these headphones they are able to continue there usual activities while not having to worry about distractions. I think Bose did a great job of using location, color, and humor in this advertisement to grab the reader’s attention.
In 1492, Christopher Columbus was a self-made man who worked his way up to being the Captain of a merchant vessel. He gained the support of the Spanish monarchs, Ferdinand and Isabella, for an expedition to the Indies. With the support of the Spanish monarchy, he set off to find a new and faster trade route to the Indies. Upon the arrival of his first voyage, Columbus wrote a letter to Luis de Santangel, a “royal official and an early supporter of his venture,” in February 1493 (35). The epistle, letter, entitled “Letter to Luis de Santangel Regarding the First Voyage” was copied and then distributed in Spain before being translated and spread throughout Europe. The Letter is held in such regard with the people as it is considered the first printed description of the new world. Through his description of the nature of the islands, Columbus decided the future fate of the islands. His description of the vast beauty of the nature around him, declares both the economic and nationalistic motivations for colonizing the new world.
...lented advertisement which is both simple and complex, which appeals to both men and women which is a very creative and pioneering job to do. Bose has actually increased its target audience by portraying a married couple on the cover; this has helped Bose to attract both, male and female customers and also married couples. this advertisement is extremely effective and make some go and buy or at least know more details about of the Bose audio system the last lines which are barely seen are trademarks which only make Bose more trust worthy among customer the last line also says that deliver depends upon available it which suggest that Bose is confident that there will be a shortage as all the sound systems will sell like hot cakes with state of the art technology and brilliant advertisement’s it is no wonder that Bose has become a pioneer in the sound system market.
In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on fossil fuels.
One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits. Solar energy is extremely ef...
The sun shines upon Earth every day, yet no one thinks much of it. Solar power’s importance, though, is above what anyone could have ever imagined. There is active solar energy, which is when solar power is converted into light, heat, cause air-movement for ventilation or cooling, or store heat for future use. Less thought of, the other type of solar energy is passive energy, which most take for granted. Solar power provides life with heat, light, and now, electricity. Solar power also plays a role in 4 of the 5 areas of green technology: energy, green building, environmentally preferred purchasing, and green chemistry. All in all, solar power is quite a unique form of energy.
Non-verbal communication doesn’t involve words, but is a powerful form of communication. The way your body language is tells the other party whether or not you are receiving their message or just listening. When your nonverbal behaviors align with the words you’re saying, they indicate to the person you are communicating with that you are trustworthy. When non-verbal behaviors do not align with your message it sends mixed signals on what you are trying to convey. When communicating in business it is imperative that you are conscious of your own body language and nonverbal cues as well as that of
I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
