Entropy and the Second Law of Thermodynamics—The Nonequilibrium Perspective [PDF]
Entropy, 2020 An alternative to the Carnot-Clausius approach for introducing entropy and the second law of thermodynamics is outlined that establishes entropy as a nonequilibrium property from the onset.

The Second Law of Thermodynamics [PDF]
, 2015 Clausius was one of the principle architects of the science of thermodynamics. In 1850 he published a groundbreaking paper entitled On the Moving Force of Heat and the Laws of Heat which May Be Deduced Therefrom. In this paper he criticized the caloric theory of heat—upon which Carnot’s work had been founded—on the grounds that it violated the first ...

The Origins of Time-Asymmetry in Thermodynamics: The Minus First Law [PDF]
Studies in History and Philosophy of Science Part B - Studies in History and Philosophy of Modern Physics, 2001 This paper investigates what the source of time-asymmetry is in thermodynamics, and comments on the question whether a time-symmetric formulation of the Second Law is ...

Bluff Your Way in the Second Law of Thermodynamics [PDF]
Studies in History and Philosophy of Science Part B - Studies in History and Philosophy of Modern Physics, 2001 The aim of this article is to analyse the relation between the second law of thermodynamics and the so-called arrow of time. For this purpose, a number of different aspects in this arrow of time are distinguished, in particular those of time-(a)symmetry ...

The Second Law of Thermodynamics and the Heart
Future Cardiology, 2012The second law of thermodynamics explains the phenomenon of irreversibility and the increasing entropic trend of nature. Similar to human-made machines, living structures are subjected to entropy generation, becoming 'worn' and 'damaged' from use. However, they have the possibility of eluding or deferring these processes.

GRAVITATION AND THE SECOND LAW OF THERMODYNAMICS
International Journal of Modern Physics D, 2004Just as gravitons can carry energy, they can also be used to transmit information. It follows that an entropy should be associated with gravitational degrees of freedom, independent of the presence or absence of black holes. In this essay, we discuss how one might count gravitational entropy given a classical gravitational field.

Though the balance of entropy has been denoted as Second Law of Thermodynamics in the previous chapters, its classical formulation comes along with thermodynamic cycles. Thus, the focus now is on these cycles. However, there are two different types of thermodynamic cycles: Clockwise cycles on the one hand convert heat into mechanical energy and are ...

The second law of thermodynamics
1991The first law of thermodynamics was developed in Chapter 4 from a study of the effects of adiabatic work on the state of a system. This law introduces the concept of internal energy (a non-primitive state function) and imposes certain limitations on the changes that can occur in a system under given constraints.

Life and the Second Law of Thermodynamics
Nature, 1946WHETHER life processes obey the second law of thermodynamics or if life finds a way of evading the otherwise universal dissipation of energy has been something of a puzzle for a century. Kelvin left the matter open in his formulation of the Second Law, by expressly excluding the operations of ‘animate agencies’.
