## Perfect Ratios

While working on drawings for pi is by design, I noticed a propeller like shape.

Perhaps indicating optimum air/water flow possibilities for aircraft, ships, etc.

__This design has many interesting features, such as:__

The small blue diamond sitting on top of the red line contains the location for π 3.14159...,

All horizontal and vertical measurements end with the repeating remainder 142857

The proportions/ratios of this design are as perfect as 22/7 (3.142857...)

The two circle diameters 64.28...% / 35.71...% = 1.8

The number seven recurs frequently, for example, the height of the 100mm propeller (or %),

divided by one-half the thickness of the central disk (14.285714...mm) is 7.

The disk diameter 53.428... / 17 = 3.142857..., and 17 is the 7th number in the list of primes.

The circle diameters decrease toward the center by 3.5 x. There is also a Sun and Planets link.

Right triangles.

The central disk correctly depicted as football shaped in these next images.

Perfect ratios and patterns are a universal phenomenon,

and the torpedo shaped Bluefin Tuna is one such example.
