“This law (regarding the theoretical efficiency of heat engines by Mr. Joule), and the law of the maximum efficiency of heat engines, are particular cases of a general law which regulates all transformation of energy, and is the basis of the Science of Energetics.” LawEnergyCasesParticularBasesTransformationHeatEnginesEfficiencyMaximumTheoretical Author:William John Macquorn Rankine
“Now these two questions Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics. Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics.” IfsDoeTwoRealityLawUsedObjectsMaterialsTheorySourceAimMethodAppearancePhysicsResolutionSensibleMetaphysicsTheoreticalSubordinatesAutonomousTheoretical Physics Author:Pierre Duhem
