Definition of entropy in English:

entropy

nounˈɛntrəpiˈɛntrəpi

mass noun

1Physics
A thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.
〔物理〕熵（符号： S ）
the second law of thermodynamics says that entropy always increases with time
count noun the sum of the entropies of all the bodies taking part in the process
Example sentencesExamples
- It will occur because according to the second law of thermodynamics, the amount of entropy in a system must always increase.
- In Chapter 3 we discussed how the thermodynamic arrow of entropy increase is a reflection of the relative probabilities of various states.
- Then it recovers its investment by letting the sodium back in, so increasing entropy, and converting that change in entropy to free energy used to turn the rotor.
- The enthalpy, entropy, and free energy changes in the opening reaction of each basepair are determined from the temperature dependence of the exchange rates.
- Despite the large increase in enthalpy and entropy, the free energy difference between the closed and open conformations is relatively small.
2Lack of order or predictability; gradual decline into disorder.
〈喻〉无序；渺茫；越来越乱
a marketplace where entropy reigns supreme
一个混乱不堪的市场。
Example sentencesExamples
- Lyrically and musically, the album's tone of entropy does more to underscore the miasma of dread most people feel under the current political conditions than it does to rebel significantly against it.
- He was unable to arrest the gradual entropy that had set in.
- Designers, even more than artists, are battlers against entropy.
- Patrick's final resting place wasn't quite as romantic as she'd envisioned it, but after a day in this town where entropy seemed to reign unchecked, she was unsurprised.
- People have a natural tendency to rebel against entropy to return order to their environments.
Synonyms
disorder, disarray, disorganization, disorderliness, untidiness, chaos, mayhem, bedlam, pandemonium, madness, havoc, turmoil, tumult, commotion, disruption, upheaval, furore, frenzy, uproar, babel, hurly-burly, maelstrom, muddle, mess, shambles
3(in information theory) a logarithmic measure of the rate of transfer of information in a particular message or language.
（信息论中的）熵，平均信息量
Example sentencesExamples
- These functions range from simple bookkeeping tasks to serious number-crunching algorithms such as deconvolution, maximum entropy, Fourier transforms and more.
- But no serious scientist would expect that such a thing were possible, for the simple reason that it would be a violation of the fundamental principles of entropy / information theory.
- One can measure entropy on a scale from zero to one - zero indicating a completely linear system that loses no work and behaves predictably.
- Information, entropy, and computation become metaphors for us at a much broader level.
- Changes in entropy or information content based on new constraints are calculated with respect to the appropriate reference state which can, in principle, be related to other reference states.

Derivatives

entropic

adjectiveɛnˈtrɒpɪk

Cliche is symptomatic of an entropic democracy where meaningless statements are repeated unconsciously by the masses.
Example sentencesExamples
- In keeping with the general entropic tendency of the universe, all my futile efforts at gathering and retaining, my naïve tendency toward nest-egging, fly directly in the face of the entire universe itself!
- The problem seems to be that while we can fix it as much as we like, it only stays fixed until the next time I post something, at which point it just reverts to its natural entropic not actually working sort of state.
- The other problem with paranoia is that it tends to become exhausting being so cynical and suspicious and any entropic system needs a continuous input of energy to continue working rather than excessive expenditures.
- By tending towards the whole, it is possible to conceptualize the equalizing of difference in a fully entropic global communication system.

entropically

adverbɛnˈtrɒpɪk(ə)li

Thermodynamically, the migration of nonbinding particles to these weakened microdomains is entropically favorable because it maximizes particle motions.
Example sentencesExamples
- The decondensation is entropically driven due to the higher number of ligand binding sites in decondensed DNA in comparison with the condensed molecules.
- In this case, thrumming bass plucks and bouncing ball patterns entropically expire amidst wheezing exhalations and electrical shimmer.
- Furthermore, as the DNA unbinds entropically at extensions before the overstretching transition, these calculations predict that the plateau will not be seen in the force-extension curves for a dodecamer, as is indeed the case.
- The extent to which the DNA binding of a given protein will be enthalpically or entropically driven is a function of solution conditions, such as temperature, salt concentration, pH, etc.

Origin

Mid 19th century: from en-² 'inside' + Greek tropē 'transformation'.
