The golden section point is the point that divides a line segment into two parts, so that the ratio of the length of the original line segment to the longer part is the golden section number. There are two such points on the line segment. 0.6 18 is the golden ratio. Facts have proved that 0.6 18 is fully reflected in the fields of architecture, calligraphy, painting, music and so on, and medicine is inextricably linked with 0.6 18, which can explain why people feel most comfortable when the ambient temperature is 22 to 24 degrees Celsius. Because the product of normal body temperature of 37 degrees Celsius and 0.6 18 is 22.8 degrees Celsius, at this ambient temperature, human metabolism, circadian rhythm and physiological function are in the best state. Recently, when studying the relationship between "golden section" and human beauty, medical aesthetics experts in China found that there are at least 18 golden section points in bodybuilders' appearance structure. (1) navel: the dividing point between the top of the head and the bottom of the foot; (2) Throat: the dividing point between the top of the head and the navel; (3), (4) Knee joint: the dividing point between navel and sole; (5) and (6) elbow joint: the dividing point from shoulder joint to middle fingertip; (7) and (8) nipple: the dividing point on the longitudinal axis of trunk nipple; (9) Eyebrow point: the dividing point between hairline and chin base 1/3 and 2/3; (10) Subnasal point: the dividing point between hairline and chin base 1/3 and 2/3; (1 1) lip bead point: the dividing point of 1/3 and middle and lower 2/3 in the distance from nasal root to mental root; (12) straight line point of chin and labial groove: 1/3 and upper middle 2/3 take the distance from the base of nose to the base of chin as the dividing point; (13) Left corner point: the boundary point between the left 1/3 and the right 2/3 of the horizontal line of the oral fissure; (14) Right corner point: the boundary point between the right 1/3 and the left 2/3 of the horizontal line of the oral fissure. (15) Two thirds of human body is water; In the environment of 22.5℃, the metabolism of human body is in the best state, which is 0.6 18 times of the normal body temperature of 36.5℃. (16) The heart center is located at the golden section of the thoracic cavity; (17) 0.6 18 of the whole spine is the thoracolumbar dividing line, that is, 12 thoracic vertebra, 0.6 18 from shoulder to fingertip of middle finger is elbow joint, 0.6 18 from elbow joint to fingertip of middle finger is wrist joint, and 0.666 from knee joint to toe. (18) graceful and slim fashion models, as well as dancers who have just danced, their leg-to-figure ratio is also similar to 0.6 18. In addition, the golden section related to human body also includes: 12 months in a year, and 0.6 18 of 12 is 7.4. In July and August, there are the most lymphocytes in human blood, which can participate in resisting the invasion of bacteria, so this is the period when human body has the strongest resistance. The lowest temperature in a day is at 2 am and the highest temperature is at 14. The golden section between the two is 9.4, and the temperature of 10 is the most suitable in a day. At this time, people's thinking is clearest and their work efficiency is highest. The positions of Zaobaihui, Yongquan and Laogong, the three main points of TCM fitness, also conform to this division rule: Baihui is located at 0.6 18 of the front hairline to the back hairline, Yongquan is located at 0.6 18 of the palm, and Laogong is located at 0.6 18 of the palm. Some knowledge of mathematics has been learned in our life, but we haven't found the law yet. We can use experience and refine it into mathematics through practical activities. The essence of the golden section is the magic number 0.6 18. As long as you pay attention, you will find its "phantom" in all aspects of life. The golden section was discovered by the ancient Greek philosopher Pythagoras, and the golden ratio of 1: 0.6 18 is the most beautiful and harmonious.
