Leonardo Fibonacci / Leonardo Pisano (1170–1250)
Fibonacci was an Italian mathematician. Famous mainly for his contribution to the transition to the decimal counting system, instead of the Roman numerals in Western Europe,
After being exposed to it in India and Arab countries,
and also because of the series of numbers he defined, named Fibonacci series.
In the Fibonacci series, each limb is the sum of the two limbs preceding it, The first members of the series are:
0, 1, 1, 2, 3, 5, 8, 13, and so on. A rectangle that formed from the addition of the numbers of the Fibonacci series is a Golden Rectangle, a rectangle whose ratio between its sides is "Golden Ratio" (approximately 1,618)
I the case of our watch, we use this special spiral,
instead of the hours hand on regular clock. Explanation how to read the clock Click Here.
The use of the golden ratio in art dates back to ancient Egypt. The ancient Egyptians were probably
the first to incorporate mathematics into art, long before the "Fibonacci series" was born.
At the beginning of the 13th century, the mathematician Leonardo Fibonacci described the ratio of
two consecutive members in a series of integers, each equal to the sum of its two predecessors.
The ratio he found was approximately equal to the number 1.618 (see box).
What is it that makes the irrational number 1.618 so valuable in the context of beauty and aesthetics?
The golden ratio is in fact a geometric principle, which concerned the division of a section
into different parts in size, so the ratio of the small part to the large is like the ratio of the large part
to the whole section. The golden rectangle, then, is a rectangle whose ratio is its width Its length is
equal to the ratio between its length and half its circumference. This attitude, it turns out, produces beauty.
The golden ratio has many occurrences in nature
(in the arrangement of petals, in the shape of shells etc)
And dating back to classical Greece,
it is also used in art and architecture.
In Nature
In art
In ancient architecture
In modern architecture
The golden ratio encompasses almost every area of our lives. In every perfect object and spectacle you see around, you can search and find the golden ratio,
Or as it is known: "Divine Proportion".
