Gold separation point

About 0.618 points to 0.618:1 is at the forefront of two parts. make the original line with the longer length of that portion of the ratio of 0.618 points. Segment on the two points. The use of two lines 0.618 points can be made is five-pointed star, is pentagon. More than 2,000 years ago, ancient Athens, Greece's third-largest school mathematicians EU first proposed Texas Road 0.618. The so-called golden section that is the length of the L line is divided into two parts, so that part of the ratio for all, to the other part for the part now. 0.618 calculated on the most simple method is the calculation Feibeijie series 1,1,2,3,5,8,13,21. ... After two 2/3,3/5,4/8,8/13,13/21 ratio of the number, the approximate .... 0.618 before and after the Renaissance, after the Arabs into Europe, have been welcomed by the Europeans, They call it "the law", 17th century Europe a mathematician, even nicknamed it "the algorithms can be the most valuable algorithm." This algorithm in India known as the "three rate" or "three rules", we often talk about the ratio method. In fact, the "golden section", China is also recorded. Although no ancient Greece early, but it is ancient China to create an independent mathematician, but later came to India. After verification. Europe's share algorithm is derived from China through India and into Europe by the Arab, and not directly into the ancient Greece. In the plastic arts because it has aesthetic value, arts and crafts and daily necessities Chang design, The ratio used to arouse people's sense of beauty, the real-life application is very extensive, Buildings certain segments than on the scientific use of the Golden Section, the arena is not a member of the narrator standing in the arcade before the stage, 35 in the side of the platform to stand on the stage length of 0.618 points on the most beautiful, the best voice transmission. Even the vegetable kingdom are still using the Golden Section, a softwood from the top down, will see the gold leaf is divided in accordance with the law with the ASEAN. In many scientific experiments, select the program used a .618 law, optimization, It allows us reasonable arrangements for the less number of tests to find reasonable and appropriate Western conditions. It is precisely because of the construction, cultural, industrial and agricultural production and scientific experiments which have extensive and important applications, So people were precious to call the "Golden Section."
