In the first half of the eighteenth century, French philosopher and mathematician Émilie du Châtelet made notable contributions to the emerging theoretical framework of energy by proposing a form of the law of conservation of energy that recognized the inclusion of kinetic energy. Empirical developments of the early ideas, in the century following, wrestled with contravening concepts such as the caloric theory of heat.

Thermodynamics - The second law of thermodynamics

The Onsager reciprocal relations have been considered the fourth law of thermodynamics. They describe the relation between thermodynamic flows and forces in non-equilibrium thermodynamics, under the assumption that thermodynamic variables can be defined locally in a condition of local equilibrium. These relations are derived from statistical mechanics under the principle of microscopic reversibility (in the absence of external magnetic fields).
