If a human places their hand on a wooden desk, the sense of touch and solidity is actually provided by the repulsion effect of the electron shells of the atoms in the hand and desk giving feedback to the various sensors in the human body.
Can these two things actually physically touch at the atomic level?
In this case we are defining "touch" as the atoms of the hand and desk coming as close to each other as the atoms in the desk are to each other normally.
Using only human muscular power to close the distance, can it be proven that a hand and the wooden desk have physically touched as per the given definition?
