Illustrated, in full colour, this second book of the "MEMENTO 13" series addresses numbers by stretching the observation from the Pythagoreans' philosophy on numbers, then through numerology's emphasis on the influence of numbers on our life, to the insight on figurate and master numbers. The chapter "Thirteen Stories" has thirteen sections and each of them introduces one of the numbers, from One to Thirteen. The emphasis is given to qualitative and geometrical side of numbers, and to their complex persona. Reader learns to look at numbers as at some new companions in life, by understanding the indispensable omnipresence of numbers in every design, analysis or event. As a common denominator of the entire Creation, numbers define and connect all, and we can find them in the geometry of every shape that surrounds us.
