Star report - Essay Example Though it is not as visible from the earth, the Proxima Centauri is the main sequence star. The star is thus the main sequence red dwarf star, and like the sun has a low luminous value compared to the degenerate (white) dwarf stars that run on star remnants. The energy generated by the star (magnetic, X-Rays, and surface flares), is promoted by the thermonuclear fusion of hydrogen not accumulating helium ash at the core. This lengthens the lifespan of the star, which is estimated to be when the star burns through all of its fuel. The Proxima Centauri is the star nearest to the sun. As such, its nomenclature is founded in the distance to the sun. The term Proxima is derived from Latin and translates either as ‘next to’ or ‘nearest to’. It applies to both the sun and the earth, as it is the closest star to the earth after the sun, making the name proper name. Discovered in 1915 by Robert Innes (Scotsman), it is located in the G-cloud in the Centaurus constellation, with an estimated orbital period of more than half a million years (Benedict et al 1086). The myth to the constellation is that it was believed to be a bison-man by the Babylonians, similar to the Greek and Roman concept of the centaur, half horse-man. The star has a visual magnitude of 11.05 and is only visible with the use of visual aids, but its absolute visual magnitude is 15.5. Its invisibility to the naked eye follows the limitation of the eye’s visual magnitude, placed at 6. There are proposals that suggest that the star makes up the triple star system with the A and B Alpha Centauri. Such is part of the binary Alpha Centauri with about 0.237 Â ±0.011 ly (about 15.000 Â ± 700 AU (Astronomical Unit) (Benedict et al 1088). Considering its proximity, the angular diameter (1.02 Â ± 0.08 milliarcsec.), and length from the sun, its diameter has been determined as a seventh that of the sun. With this

Is elitism or pluralism a better explanatory theory of the way Essay - 1

Is elitism or pluralism a better explanatory theory of the way American government and politics really operates Why so - Essay Example In simple words, elite administration is an administration which is based on the vested interests of a specific economic class. Pluralism, on the other hand is based on diversity and acceptance and is stated to be implemented for the common good of the people. With special regards to a modern economic, social and political development, pluralism is considered to be the most effective and cost efficient system. Elitism and pluralism are two separate entities. If you feel the need to differentiate between the two, you would need to study their individual characteristics. (Elitism: The future of american foreign policy: elitism versus pluralism) Although there are various attributes attached to the elite, there is no single definition of the term. Likewise, the term elite can also be used to describe a class or group of people who have the required wealth and the essential social status to influence class determination. Listed below are a few personal attributes which are directly linked to the elitist theory. The pluralism concept is often considered essential for the US set up as it is not individualistic in nature and is governed owing to numerous resources. These resources can enhance the overall power of the politicians by providing opportunities in terms of legal authority, prestige, knowledge, skill and monetary benefits. Henceforth, as compared to elite system, the pluralism theory is ideal for the US set up. (Allaboutreligion) (Bryner) The biggest reason which advocates the concept of pluralism is the ability of the pluralistic society to differentiate between potential and actual power. Actual power is undoubtedly the ability to force an individual through compulsive force whereas potential power is the ability to transform a potential resource into usable power. A perfect example of this concept is the currency bills. If there is no power attached to cash, the bills would continue to remain plain pieces of paper and vice versa. The pluralist
