The Casimir effect describes the attraction between two uncharged conducting plates placed parallel to each other in vacuum. The astonishing force (predicted in 1948 by Hendrik Casimir) per unit area of each plate depends on the planck's constant (h),speed of light (c) and separation between the plates (r) such that F = k
