The quantum of action, which a layperson can consider as the smallest possible state change, is actually Planck's constant. https://en.wikipedia.org/wiki/Planck_constant https://en.wikipedia.org/wiki/Planck_constant All energy refers to is an amount of state change that is occurring every second that some quantity of energy exists. That's why action has units Energy x Time. You can divide by time and you get Energy = Actions per Second, kinda like APM in Starcraft.. https://en.wikipedia.org/wiki/Action_(physics) https://en.wikipedia.org/wiki/Action_(physics) Principle of least action is really the principle of "least change." In summary, computation is happening -- but most of the computation that energy does while held as mass/matter is cyclic processes (aging.) Not anything interesting, at least to me or you.
