It is necessary to mention the Fibonacci numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 etc. The peculiarity of the numbers' succession is that each component, beginning with the third, equals the sum of the two previous ones 2 + 3 = 5; 3 + 5 = 8; 5 + 8 = 13, 8 + 13 = 21; 13 + 21 = 34 and etc., the adjoining numbers of the row relate to each other closly to how the numbers of the Golden Ratio relate to one another. So, 21÷34 = 0,617, and 34÷55 = 0,618.
The human body became the object of focused research using the Golden Ratio principle. Zeising accomplished colossal work. He measured about two thousand human bodies and came to the conclusion that the Golden Ratio describes an average rule. The division of the body in the navel point is the most important indicator of the Golden Ratio. The proportions of the body of a man waver within the average of 13÷8 = 1,625 and come closer to the Golden Ratio than the proportions of a woman’s body, as for which the average proportion is expressed in the 8÷5 = 1,6 relation.
