This is an attempt to establish a simple approach to nonequilibrium thermodynamics. A generalized entropy is formulated from an information theory viewpoint and from a thermodynamic viewpoint. Rate laws, coupling phenomena, equality of cross coefficients, and a criterion for the changes of the steady state, all emerge when the maximum entropy of information is linearly related to the thermodynamic entropy. The results are not strictly new but their integration in one simple approach is believed to be novel.

The Relationship

In this paper, we present a derivation of the black hole area entropy with the relationship between entropy and information. The curved space of a black hole allows objects to be imaged in the same way as camera lenses. The maximal information that a black hole can gain is limited by both the Compton wavelength of the object and the diameter of the black hole. When an object falls into a black hole, its information disappears due to the no-hair theorem, and the entropy of the black hole increases correspondingly. The area entropy of a black hole can thus be obtained, which indicates that the Bekenstein–Hawking entropy is information entropy rather than thermodynamic entropy. The quantum corrections of black hole entropy are also obtained according to the limit of Compton wavelength of the captured particles, which makes the mass of a black hole naturally quantized. Our work provides an information-theoretic perspective for understanding the nature of black hole entropy.

Steady State Behaviour

Brushless drives are important, but are often thought to be difficult to treat quantitatively at the undergraduate level. The Blondel circle diagram is shown to be ideal for illuminating the steady-state behaviour and limitations of small brushless system, at a level suitable for undergraduate courses.
