23.7.05 10:39 Did you know that... golden ratio (

)

The following information are from German wikipedia Goldener Schnitt.

You probably all know that golden ratio is the ratio between two numbers which is considered as aesthetically pleasing.

But there are some other intereting aspects mentioned in above article:

Golden ratio is represented by greek letter phi
samples: golden angle, golden rectangle, fibunacci numbers,
other ratios: 4/3=1,3: TV format, sqr(2)=1,414 DIN A4 format, 3/2=1,5 35mm film format, phi=1,618, 5/3=1,6 cinema format, 16/9=1,7 broad image TV format. So why did they choose a new format for broad image TV instead of taking cinema format (5/3) which is nearer to golden ratio? Because 16/9 relation is closer to human view.
one can build aspect ratio with compass and ruler
a pentagramm includes many golden ratio rules
the gastropod (snails, slugs...) shell sometimes follow the folden spiral rule
cheops pyramid is build so that the surface of each side is equal to the square of the high of the pyramid. Similar ratios are found in Parthenon temple or Akropolis
