11. Ponette's precocious task is to come to terms with the irreversibility of time. 12. Opponents have used that incident as an example of the irreversibility of the death penalty. 13. It is the cause of the irreversibility . 14. Current research in dynamical systems offers one possible mechanism for obtaining irreversibility from reversible systems. 15. A prime example of irreversibility is in the transfer of heat by conduction or radiation. 16. See also Arrow of time, Irreversibility , and Entropy ( arrow of time ). 17. According to Prigogine, determinism loses its explanatory power in the face of irreversibility and instability. 18. This minimizes the inevitable irreversibilities associated with heat transfer to the working fluid ( water ). 19. See the article on the second law of thermodynamics for a further discussion of such irreversibilities . 20. Due to the inherent irreversibility of heat production for useful work, efficiency levels are decreased.
