  * Brush, Stephen G.: Irreversibility and Indeterminism: Fourier to Heisenberg. Journal fo History of Ideas 37 (1976) S. 603-630.

|Abstract: By 1800, the cyclic "Newtonian clockwork universe," rejected by Newton himself, was being challenged by research on the cooling of the Earth. J. B. J. Fourier, inspired in part by this problem, was the first to establish a quantitative theory in which a physical process is not time-reversible (heat conduction). The conflict between that theory and the time-reversibility of Newton's laws became inescapable in the late 19th century when physicists tried to derive the Second Law of Thermodynamics from an atomistic model based on Newtonian mechanics. Maxwell and Boltzmann tried to do this by assuming that atoms behave as if they move randomly. With the success of kinetic theory and statistical mechanics, the phrase "as if" was forgotten, so when Einstein, Rutherford, Schrödinger, Born and Heisenberg explicitly postulated indeterminism at the atomic level, other physicists didn't have much difficulty accepting it. |


  * Denbigh, K. G.: The Many Faces of Irreversibility. The British Journal for the Philosophy of Science 40 (1989) S. 501-518.

|Abstract: Irreversibility, it is claimed, is a much broader concept than is entropy increase, as is shown by the occurrence of certain processes which are irreversible without seeming to involve any intrinsic entropy change. These processes include the spreading outwards into space of particles, or of radiation, and they also include certain biological and mental phenomena. For instance, the irreversible and treelike branching which is characteristic of natural evolution is not entropic when it is considered in itself—i.e. in abstraction from accompanying biochemical and physiological activity. What appears to be the common feature of all forms of irreversibility is the fanning out of trajectories, new entities or new states, in the temporal direction towards the future.|
