In search of a physical theory of time.

The variable time considered in science is a measurement. The relation of time to other variables is expressed in rates, and the variable time is seldom explicitly included in equations describing chemical reactions or radioactive decays. Recalling that the Greek word atom is applicable to indivisible particles in both spatial and temporal worlds, the term chronon is proposed to designate elementary particles of time in parallel to the atom in space. Considerations of interactions of chronons with material and nonmaterial objects could promote understanding of several paradoxes in physical and biological sciences.
