![]() ![]() 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. Ahmed Almheiri, Scientific American, 17 Aug. 2021 This is the island formula for the entanglement entropy of the Hawking radiation. One of the ideas involved in the concept of entropy is that nature tends from order to disorder in isolated systems. La entropía se refiere al número de estados que puede tener un sistema. 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. After mean forces of the free energy with respect to the CVs were determined from restrained QM/MM molecular dynamics (MD) simulations, steepest descent. Entropy is not energy entropy is how the energy in the universe is distributed. ![]() Quanta Magazine, That flaw is entropy, which builds up as a universe bounces. 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 scientific concept, as well as a measurable physical property, that is most commonly associated with a state of disorder, randomness, or uncertainty. Jennifer Ouellette, Ars Technica, 2 Dec. Information theory finds applications in machine learning models, including Decision Trees. Events with higher uncertainty have higher entropy. In information theory, a random variable’s entropy reflects the average uncertainty level in its possible outcomes. The probability of finding a system in a given state depends upon the multiplicity of that state. Entropy measures the amount of surprise and data present in a variable. For processes in which the temperature is not constant such as heating or cooling of a substance, the equation must be integrated over the required temperature range, as discussed below.Recent Examples on the Web Jacob Bekenstein realized in 1974 that black holes also have entropy. Entropy as a Measure of the Multiplicity of a System. t e In information theory, the entropy of a random variable is the average level of 'information', 'surprise', or 'uncertainty' inherent to the variables possible outcomes. This is the basic way of evaluating \(ΔS\) for constant-temperature processes such as phase changes, or the isothermal expansion of a gas.
