Parkinson's law Parkinson's law Parkinson's law is the adage that "work expands so as to fill the time available for its completion". It is sometimes applied to the growth of bureaucracy in an organization. This law is likely derived from ideal gas law, whereby a gas expands to fit the volume allotted. Articulated by Cyril Northcote Parkinson as part of the first sentence of an essay published in "The Economist" in 1955 and since republished online, it was reprinted with other essays in the book "Parkinson's Law: The Pursuit of Progress" (London, John Murray, 1958). He derived the dictum from his extensive
Entropy (arrow of time) the speeds and locations of the different particles are completely random, up to the need to conform with the macrostate of the system). This is closely related to the Second Law of Thermodynamics. Take for example (experiment A) a closed box that is, at the beginning, half-filled with ideal gas. As time passes, the gas obviously expands to fill the whole box, so that the final state is a box full of gas. This is an irreversible process, since if the box is full at the beginning (experiment B), it does not become only half-full later, except for the very
