Here is the facade of the Parthenon. Hambige felt that a mathematical ratio known as the golden rectangle was used by the Greeks in its design. That is disputed today, and it depends how you choose your measuring points. Whether they did it intentionally or not, they instinctively used the proportions derived from the square root rectangle I presented last night.
What it means is that there is a mathematical relationship between the two pieces of line one is 1.683 (it is actually along irrational number) times longer than the short piece. There is the ratio.1.683.
Lots of things we deal with in the world use these proportions, or something close to them. here is an example below of those proportions.
The grill of this Bentley has approximately this shape turned vertically. Books and notebook paper, many standard sized artist's canvasses and the pelvises of rich Hollywood movie stars bear these same proportions.
I would like to congratulate Rima Fakih on winning the Miss USA pageant. I have in the past insisted that Taylor Swift was the most talented young woman in America....now I'm not so sure.
