![]() These examples are programmatically compiled from various online sources to illustrate current usage of the word 'entropy.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Sebastian Smee, Washington Post, After seven years in the Hammerskins, exhaustion and entropy were setting in. 2022 Succumbing to something closer to entropy than evolution, the watercolor starts to puddle and bruise. Thermodynamics deals with the relation between that small part of the universe in which we are interested - the system - and the rest of the universe - the surroundings. There is a constant amount of energy in the universe, but the way it is distributed is always changing. Entropy is dynamic - something which static scenes dont reflect. Ahmed Almheiri, Scientific American, 17 Aug. Entropy is not energy entropy is how the energy in the universe is distributed. 2021 This is the island formula for the entanglement entropy of the Hawking radiation. Conor Feehly, Discover Magazine, 3 Nov. James Riordon, Scientific American, In short, the tendency for systems to move from low entropy to high entropy, the particular spacetime conditions of our solar system and the indeterminacy of the future combine to create our particular conception of time. James Riordon, Scientific American, The expansion allows the universe to smooth out, dissipating the entropy before collapsing again. Entropy is a measure of the amount of energy that is unavailable to do work in a closed system. Quanta Magazine, That flaw is entropy, which builds up as a universe bounces. Entropy is a thermodynamic property, like temperature, pressure and volume but, unlike them, it can not easily be visualised. Entropy is a scientific concept, as well as a measurable physical property, that is most commonly associated with a state of disorder, randomness, or uncertainty. 2022 If the entropy of the system decreases, the entropy of the environment must increase such that the sum of the two entropies can only increase or stay the same, but never decrease. Entropy is a dimensionless quantity that is used for measuring uncertainty about the state of a system but it can also imply physical qualities, where high entropy is synonymous with high disorder. Jennifer Ouellette, Ars Technica, 2 Dec. Therefore, new definitions based on FC can generalize both concepts in the theoretical and applied points of view. However, FC is not yet well disseminated in the community of entropy. ![]() Recent Examples on the Web Jacob Bekenstein realized in 1974 that black holes also have entropy. Several new entropy definitions have been proposed in recent decades, expanding the scope of applicability of this seminal tool. ![]()
