Fingertips, Physics and other things I don't know about.

Fake finger reveals the secrets of touch : Nature News
"The vibrations are picked up by nerves. But some of the nerve endings, called Pacinian corpuscles, are relatively deep — about 2 millimetres — under the skin, raising questions about how they could detect such subtle vibrations." (Kwock, 2009)
Fingerprints are an intricate topography tailored to each persons sensory perception. Its all about the surfaces, The architecture of world where texture and energy is everything. The simple interaction between the surface of a finger on fabric gives us it's texture, durability and warmth. The nanostructure of both these surfaces communicate1 to each other by altering the climate of the space between them, and our highly evolved neurological system interprets the relevant information.
I was reading a book called boundary layer physics By T.R Oke about climatology of the lower portion of the troposphere, called the boundary layer, where the wind on the earth surface is impacted by the resistance to the ground. In other words, its the important part of the air column where all the plants and animal breathe and the water and wind dance.
One major point that came out of Oke's book was that topography was the main factor that influences the movement and interaction between the surfaces of the air and earth. A gentle sloping mountainside positioned downwind acts the same as a airplane wing and creates turbulence on its lee side. Decreasing or increasing the weight of the air on the earth surface (high and low pressure systems) alters the way that topography influences wind patterns in a predicable manner (at least predictable as far as the weatherman is predictable).
Couldn't this be the same thing with our fingertips? They have a topography designed to generate a specific frequency that casues our nerves to fire eltiric charges in our brain. . How is this any different that the earth spinning mountains around in the wind and creating thunderstorms?
1Perhaps communicate is inaccurate for it implies sentience of the fabric (though the argument for animism is one I would gladly indulge should anyone be interested).
