Extrinsic and Intrinsic Irreversibility in Probabilistic Dynamical Laws
نویسنده
چکیده
Two distinct conceptions for the relation between reversible, time-reversal invariant laws of nature and the irreversible behavior of physical systems are outlined. The standard, extrinsic concept of irreversibility is based on the notion of an open system interacting with its environment. An alternative, intrinsic concept of irreversibility does not explicitly refer to any environment at all. Basic aspects of the two concepts are presented and compared with each other. The significance of the terms extrinsic and intrinsic is discussed.

Relativity and Irreversibility
The dynamical laws of physics in their conventional formulation are time reversible. The description of irreversible phenomena was always thought to be incompatible with the dynamical laws. We have recently discussed [1, 2, 3, 9, 10, 11, 12] the origin of irreversible behaviour due to resonances in various Poincaré nonintegrable quantum systems. The analytic extension of the Hamiltonian or Liou...
متن کاملThe Psychological Function of Nostalgia: Increasing Intrinsic Self-Expression and Decreasing Extrinsic Self-Definition
Previous findings have shown the many functions of nostalgia, for example, increasing mental health, and the current research aimed to explain those findings by testing the theoretical explanation that the benefits of nostalgia come from the fact that nostalgia reminds us of our intrinsic self. Aiming to investigate the effect of nostalgia on authenticity (intrinsic self-expression) and extrins...
