entropies in English

noun
1
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.
Despite the large increase in enthalpy and entropy , the free energy difference between the closed and open conformations is relatively small.
2
lack of order or predictability; gradual decline into disorder.
a marketplace where entropy reigns supreme

3
(in information theory) a logarithmic measure of the rate of transfer of information in a particular message or language.
These functions range from simple bookkeeping tasks to serious number-crunching algorithms such as deconvolution, maximum entropy , Fourier transforms and more.
