Compare reading - Essay Example Electronic music is music produced by means of electronic musical instruments. Examples of instruments that produce electromechanical sounds are the telharmonium, or also known as dynamophone, Hammond organ, and electric guitar. Devices like the sound synthesizer and Theremin can be used to produce electronic sound (Holmes, 2002). The capacity to record sounds is usually associated with electronic music production, but not totally needed for it. The very first documented recording equipment was invented by Edouard-Leon Scott de Martinville in 1857, the phonautograph (Manning, 2013). A number of instruments were invented that used electromechanical designs and they encouraged the eventual appearance of electronic instruments. But the technological development that has made the biggest impact on music within the first half of the 20th century is the invention of the Telharmonium. The Telharmonium was invented by Thaddeus Cahill in the early 20th century. The microtonal scales were one of the most important developments in early 20th-century music made possible by the presence of telharmonium (Barela, 1997). As stated by Ferruccio Busoni, â€Å"Only a long and careful series of experiments, and a continued training of the ear, can render this unfamiliar material [microtonal scales] approachable and plastic for the coming generation and for Art† (Barela, 1997, p. 31). Telharmonium: The Musical Invention that Electrified the World The vitality of invention which emerged before the advent of the 20th century was simultaneous with a cultural interest in the new technological advancements that was unmatched. Inventors like Edison and Bell became legends who led a philosophy of industrial growth based on the capacity of controlled electricity. Among this group of inventor capitalists was Thaddeus Cahill, creator and designer of the original musical synthesizer, and originator of the electric typewriter (Dunn, n.d.). Although several attempts to create electronic musical equipment were initiated in early 20th century by William Duddell and Elisha Gray, they were somewhat uncertain or merely the consequences of other studies on electrical technology (Holmes, 2008). The invention of Cahill, the Telharmonium, is still the greatest and most determined effort to build an electronic musical instrument ever imagined. Under overwhelming technical challenges, Cahill was able to build the first model of Telharmonium in 1900. This electro-mechanical equipment made up of 145 alternators able to generate five octaves of changeable melodic content similar to orchestral quality. Its main function was composed of what is now called additive synthesis—a sound synthesis method that produces timbre. Because Cahill’s instrument was created prior to the availability of electronic amplification he had to make alternators that generated at least 10,000 watts (Dunn, n.d., pp. 2-4). Even though Cahill’s original purpose was merely to build a gen uinely advanced electronic instrument that has the ability to perform classical musical selections, he immediately aimed at its industrial use with the intention of providing music to private settings (e.g. homes) as a way of funding its construction. He built the New York Electric Music Company with this purpose in mind and embarked on

Pakistan's need for economic growth focusing on solar energy and Research Paper

Pakistan's need for economic growth focusing on solar energy and working water filtration plants - Research Paper Example Energy is required to operate any institution in the modern world. On the other hand, the management of energy and its efficient use can reduce the demand of energy. Energy efficient devices and appliances save a lot of electrical units. Electrical energy is mostly generated by utilizing the fossil fuel resources. With the passage of time, the fossil fuel resources are becoming short due to the depletion in the fossil fuel reservoirs. As, the supply is becoming short the demand of the fossil fuel resources is rising and thus the value of the fuel resources is increasing. It is a general concept that fossil fuel based generated power is considered the costliest power as compared to hydro power or solar or wind. A research designed to evaluate the water shortage in the world depicts that about 1.3 billion people worldwide suffer from water shortage. People, in the underdeveloped and developing regions of the world, are more likely to catch the diseases that are transferred from contami nated water. Water contamination kills more people in underdeveloped regions than cancer, aids and other such diseases. People are less aware of water filtration and treatment. Small scale water filtration plants can solve the problem and prevent diseased water from entering the human body. Low energy consuming filtration plants based on solar distillation, RO filtration or other water purification methods can be utilized that consume less energy and still maintain the acceptable quality of water. Pakistan shows the similar conditions as other under developed countries due to the lack of the clean drinking water, lack of electrical energy, lack of heath services and lack of economic stability. A deep study depicts that the cost of electrical energy in Pakistan is 13 times the cost of electrical energy in Saudi Arabia. There is a need to develop a small or a large scale power generation units by utilizing the solar energy in Pakistan to bring economic stability. On the other hand, it is equally important o provide people with safe drinking water by utilizing the small scale water filtration plants. Research Questions Can solar energy and small working water filtration plants bring economic stability is Pakistan and how women can play their part in he economic stability of the Country? Body of the Paper The maintenance cost of the fossil fuel based power plant is considerably high. Moreover, a fossil fuel based power plant can be only 40% efficient, as the major part of the fuel converts to waste heat. Besides the environmental perspective, it is also economically less feasible to utilize coal, oil or gas for power generation. On the other hand, in future the fuel will cost more than the current price due to its short supply in the future. The need of the time is to utilize the alternate resources for the generation of energy1. Solar and wind energy have more potential than our current needs. Solar energy can be utilized to generate power directly by utilizing t he solar photovoltaic panels. It can be adopted individually or on a large scale. It is an efficient way to generate energy. Economic Evaluation of Solar energy Solar energy converts solar radiation into electrical energy. Solar energy has two contents; one is light energy and other content is thermal energy. Solar Photovoltaic cells are capable of converting solar light into electrical energy that can be stored in batteries and can be utilized in night. Solar energy can be harnessed for individual as well as industrial demand. Solar PV panels only consume sun radiations to generate energy. Solar light is free of cost and it will remain till the solar system remains2. The
