A silvery rectangle is a one that it's side difference is side of a square equal in area: m*n=(m-n)^2
I do call it silvery since when a square is cut from it, remaining portion is golden rectangle.
The answer is positive. since any revolving object will produce radius and diameter as 1 and 2. Once they become perpendicular(fundamental factor for gravitation) square root of 5 appears within revolving system and rest of parameters appear naturally. there are two natural proportions,silvery and golden(Divine). Silvery proportion is the one that rectangle's side difference is side of a perfect square with same area value as silvery. putting silvery and golden rectangles side by side,they become a perfect square. If we cut a square out of silvery,rest is golden and if we continue cutting squares out of golden rectangle, remaining is always golden proportion as long as it goes down to nano golden rectangle. smallest integer numbers for these two are,3 by 8 and 5 by 8 which reminds me on chess board.
