4. In mathematics and the arts, two quantities are in the
golden ratio if the ratio between the sum of those quantities and
the larger one is the same as the ratio between the larger one and
the smaller. The golden ratio is a mathematical constant
approximately 1.6180339887. The golden ratio is also known as the
most aesthetic ratio between the two sides of a rectangle. The
golden ratio is often denoted by the Greek letter (phi). .
5. OTHER NAMES: Extreme and mean ratio, Medial section, Divine
proportion, Divine section, Golden proportion, Golden cut, Mean of
Phidias
6. CONSTRUCTION OF THE GOLDEN SECTION: Firstly, divide a square
such that it makes two precisely equal rectangles.
7. Take the diagonal of the rectangle as the radius to
contsruct a circle to touch the next side of the square. Then,
extend the base of the square so that it touches the circle.
8. When we complete the shape to a rectangle, we will realize
that the rectangle fits the optimum ratio of golden. The base
lenght of the rectangle (C) divided by the base lenght of the
square (A) equals the golden ratio. C / A =A / B = 1.6180339 = The
Golden Ratio
9. GOLDEN RATIO IN ARTS AND ARCHITECTURE: LEONARDO DA VINCI THE
PARTHENON THE VITRUVIAN MAN
10. Many artists who lived after Phidias have used this
proportion. Leonardo Da Vinci called it the "divine proportion" and
featured it in many of his paintings, for example in the famous
"Mona Lisa". Try drawing a rectangle around her face. You will
realize that the measurements are in a golden proportion.. LEONARDO
DA VINCI
11. THE VITRUVIAN MAN Leonardo did an entire exploration of the
human body and the ratios of the lengths of various body parts.
Vitruvian Man illustrates that the human body is proportioned
according to the Golden Ratio.
12. THE PARTHENON Phi was named for the Greek sculptor Phidias.
The exterior dimensions of the Parthenon in Athens, built in about
440BC, form a perfect golden rectangle.
13. The baselenght of Egyptian pyramids divided by the height
of them gives the golden ratio..
14. GOLDEN RATIO INHUMAN AND NATURE GOLDEN RATIO IN HUMAN HAND
AND ARM GOLDEN RATIO IN THE HUMAN FACE GOLDEN RATIO IN THE SEA
SHELLS GOLDEN RATIO IN THE SNOWFLAKES GOLDEN SPRIAL
15. GOLDEN RATIO IN HUMAN HAND AND ARM Look at your own hand:
You have ... 2 hands each of which has ... 5 fingers, each of which
has ... 3 parts separated by ... 2 knuckles The length of different
parts in your arm also fits the golden ratio.
16. GOLDEN RATIO IN THE HUMAN FACE The dividence of every long
line to the short line equals the golden ratio. Lenght of the face
/ Wideness of the face Lenght between the lips and eyebrows /
Lenght of the nose,Lenght of the face / Lenght between the jaw and
eyebrows Lenght of the mouth / Wideness of the nose, Wideness of
the nose / Distance between the holes of the nose,Length between
the pupils / Length between teh eyebrows. All contain the golden
ratio.
17. GOLDEN RATIO IN THE SEA SHELLS The shape of the inner and
outer surfaces of the sea shells, and their curves fit the golden
ratio..
18. GOLDEN RATIO IN THE SNOWFLAKES The ratio of the braches of
a snowflake results in the golden ratio.
19. GOLDEN SPRIAL The Golden Spiral can be seen in the
arrangement of seeds on flower heads.
