The present has the past only as information (memory). Information is transformed into action in the present. The physical quantity of (quantum) information is transformed directly and explicitly into the physical quantity of action by the Planck constant. Thus, the Planck constant describes quantitatively the transformation of the past (information) into the present (action) as equivalency. Nevertheless, information and action are two different physical quantities and thus two different qualities corresponding to the different qualities of the past and the present. The transformation from the past into the present is fundamentally the same in human beings and nature therefore generating a series of misinterpretations of quantum mechanics as “subjective” (ostensibly) vs. the rest science being “objective”. The past can be always represented as a series ‘well-ordered’ in the rigorous mathematical meaning. Space exists only in the present being the process of ordering of a set of well-orderings different from any point of space into a single well-ordered series of the past.
