St. Thomas Aquinas On The Existence Of God - 1048 Words

St. Thomas Aquinas is considered to be one of the greatest minds of the western world as well as one of the greatest theologians. In his work Summa Theologica, which he revised many times over the course of his life, he explored the existence of God, and there are essentially five ways in which St. Thomas Aquinas argues the existence of God. The first way is the argument from change, the second way is the argument from causation, the third argument is the argument from possibility and necessity, or the reductio argument, the fourth way is the argument from gradation of being, and the fifth way is the argument from harmony. These arguments for the existence of God are presented in his work Summa Theologica. In regards to the first argument, Aquinas states that our senses prove that things are in motion. From there, potential motion becomes actual motion, and this actual motion can turn potential motion into actual motion. The example Aquinas uses is, â€Å"Thus that which is actually hot, as fire, makes wood, which is potentially hot, to be actually hot, and thereby moves and changes it.† Because of these arguments made by Aquinas, he says that nothing can be moved by itself because if something is both in actuality and potentially at the same time, then they have to be actual in one way but potential in a different way. Additionally, going back to the wood example, â€Å"For what is actually hot cannot simultaneously be potentially hot; but it is simultaneously potentially cold.†Show MoreRelatedSt. Thomas Aquinas On The Existence Of God1338 Words   |  6 Pagesphilosophers shifted their focus primarily to proving the existence of God, as well as other religious tenets they held.

As a result he made five proofs, which he claims, prove the existence of God. With each proof there is always a beginning, a starting point, Aquinas claims it must be God that is the beginning of each. The first proof does not do complete justice to Aquinas’s claim that God exist, wh ile the fifth proof could be used alone to prove Gods existence.

CHAPTER 1. GRID SYSTEM Essay Example For Students

CHAPTER 1. GRID SYSTEM Essay Power Transmission in a country is usually done through what is known as a Grid System. The Grid System consists of extensive interconnected transmission network supplying the whole country. Its supply from a small no. of very large and highly effective power stations. The basic network is usually 132kHZ. For a very high industrialised nation they use 275,475,800,1250 kV. Most consumers receive supplies from medium voltage distribution system of 3.3kV, 415V, 240V. For heavy industry consumer they may be supplied with 11 or 33kV. The generators produce electrical power at 11kV / 25kV and it is stepped up by using a step- up Transformer (Xmer) to a value of 132kV before it is transmitted. The receiver station will step down the voltage to a value of 33kV at various distributions centres. Generating station 11kV / 25kVStep up Xmer25kV / 32kVSending station.

THE PURPOSE OF THE GRID SYSTEM.The purpose of the grid system is to maintain a secure supply of electricity at a standard voltage and frequency to consumers throughout the country. Having stated its purpose, we can now list several advantages that have resulted from its introduction:1. security of supplies;2. standardisation of frequency and voltages;3. economy;4. the ability to transmit very large loads for considerable distance without loss; and5. the ability to transfer electricity to and from different parts of the country and to step up / down the voltages using Xmers (Transformers). 6. Easy way to convert A.C to D.C but the reverce is expensiveFUNCTION OF THE GRID SYSTEM. In order to fill its purpose, The grid system must function in the following way. The National Grid Control Centre in association with the various grid control centres around the country, estimates the load required in different areas each day. This information is then used to arrange to purchase the countries power depending on the demand. In this way stations are used to their maximum efficiency, which in turn reduces the cost of generation. Due to the fact that the system is interconnected, bulk supply points can be fed from other areas, should a failure of the usual supply occur. DISADVANTAGES OF A.C TRANSMISSION:-1. Skin effect cable losses. 2. Heavy losses hence efficiency is reduced. 3. For high voltage higher harmonics are produced, hence it interferes with communication lines.

Then the current in the 3 lines would be identical the resultant current returning down the neutral would therefore be zero. The load in this case is know as a balanced load. In actual practice its hard to find it exactly balanced. Hence the neutral wire is left to carry the leftover current. The advantages of this system compared with both a single phase and 3 phase 6 wire system is like this. Suppose 3 identical loads are to be supplied with 200A each. The 2 lines for a single phase would carry a total of 600A.. This conductor (C.S.A) would only need to be 1/3 that of single phase system but being 6 lines it would still be the 50mA current of conductor material. Hence the conductor saves an increase in the 2nd case where in the 1st case if the proper cable selection is n ot used overheating of the cable occurs, this will later result in a short circuit.POWER DISSIPATION IN STAR AND DELTA 3 PHASE CONNECTION. .ufcea00b610b3632ad1bf052ec8e1a6c1 , .ufcea00b610b3632ad1bf052ec8e1a6c1 .postImageUrl , .ufcea00b610b3632ad1bf052ec8e1a6c1 .centered-text-area { min-height: 80px; position: relative; } .ufcea00b610b3632ad1bf052ec8e1a6c1 , .ufcea00b610b3632ad1bf052ec8e1a6c1:hover , .ufcea00b610b3632ad1bf052ec8e1a6c1:visited , .ufcea00b610b3632ad1bf052ec8e1a6c1:active { border:0!important; } .ufcea00b610b3632ad1bf052ec8e1a6c1 .clearfix:after { content: ""; display: table; clear: both; } .ufcea00b610b3632ad1bf052ec8e1a6c1 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ufcea00b610b3632ad1bf052ec8e1a6c1:active , .ufcea00b610b3632ad1bf052ec8e1a6c1:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ufcea00b610b3632ad1bf052ec8e1a6c1 .centered-text-area { width: 100%; position: relative ; } .ufcea00b610b3632ad1bf052ec8e1a6c1 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ufcea00b610b3632ad1bf052ec8e1a6c1 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ufcea00b610b3632ad1bf052ec8e1a6c1 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ufcea00b610b3632ad1bf052ec8e1a6c1:hover .ctaButton { background-color: #34495E!important; } .ufcea00b610b3632ad1bf052ec8e1a6c1 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ufcea00b610b3632ad1bf052ec8e1a6c1 .ufcea00b610b3632ad1bf052ec8e1a6c1-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ufcea00b610b3632ad1bf052ec8e1a6c1:after { content: ""; display: block; clear: both; } READ: Racial profiling EssayP = VIPph = Vph.IphPph = Vph .
