Many years after, during high-school, I came to face with a mysterious equation, i.e., eπ × ι + 1 = 0. This formula suggested by a great Mathematician, Leonhard Euler (1707-1783), includes the five most important symbols of mathematics! These are the numbers 1 and 0, the constant π (pi, which is the ratio of a circle's circumference to its diameter, and is approximately equal to 3.14159…), the constant e that is the base of the natural logarithm and it is approximately equal to 2.71828..., and the imaginary unit number i which is the square root of minus one. For many years, this equation was regarded as mystic formula containing representatives from each branch of the mathematical “tree”. In particular, the arithmetic branch is represented by 0 and 1, the algebra is represented by the imaginary un ...
