In thermodynamics, action thermodynamics is type of chemical thermodynamics based on the logic that energy quantums are the integral cause of action or movement in all systems, molecular, biospheric, to human systems, and that the sets of movements towards equilibriums will accord with the laws of thermodynamics. [1]

The theory of action thermodynamics was developed beginning in the 1980s by Australian environmental chemist Ivan Kennedy, originally designed to solve specific biological problems, such as ATP synthesis, but soon began to be seen in a more generalized light, universally applicable to many systems, such as neuro systems, genetic systems, and ecosystems, among others.

Action resonance theory
A part of Kennedy’s logic is what is called “action resonance theory”, arguing that action is a thermodynamic property related to entropy, resulting from impulses of energy on matter producing force, based on Max Planck’s quantum of action, h, or energy element.

Human activity
Kennedy postulates that one can understand certain aesthetic aspects of human activity, such as the appreciation of art, or act of listening to music, etc., by using a logic of action resonance, according to which the outcomes of the actions are resultant from the transmissions of intermolecular forces by quanta. Moreover, the resonant impulses form these quanta on the nearby material surfaces of molecules (electrons and nuclei) provide a variable dispersive thermodynamic force, generated particularly strongly during collisions, able to sustain the action and kinetic energy of the system of molecules. Thus, according to Kennedy, molecules are put in motion or halted by impulsive exchanges of quanta and as also deriving their current inertia form such dynamic exchange forces. [1]
