The infinite brevity of a note is constrained only by the limitations of our human and scientific resources.For example the illustrious Professor De Selby of "THE THIRD POLICEMAN "fame , proved beyond all scientific doubt that the point of needle extends many inches beyond where the human eye percieves it to end---such is the acute and fine pointedness of most stitching needles that the invisible point can be detected by a finger prick, frequently many inches away from the visual tip. This is convincingly more evident in the case of surgical needles.This same therom can be successfully applied to our human &scientific audio limitations.
