Thermodynamic Laws and Entropy Restructured from a New Perspective
  
ABSTRACT
 
Thermodynamics, in addition to Newton's laws, forms the most fundamental foundation for all areas in science and engineering. It is thus essentially required in every university in the world, but at the same time is felt as one of the most difficult/uninteresting courses. In this talk, a new framework of classical thermodynamics is introduced, and various thermodynamic variables and concepts, including entropy, are re-interpreted from a new perspective.
The basic structure of classical thermodynamics was founded more than 150 years ago, when the molecular nature of materials was not accepted yet: molecular model was established some 50 years later. Despite microscopic nature of comprising molecules is essential to the clear understanding of the properties of thermodynamic systems, current thermodynamics texts still follow the structure of the age-old framework, so are ineffective to convey the key concepts.
A new structure of classical thermodynamics is possible, if only one physical fact, or at least one presumption, is accepted, instead of the four thermodynamic laws. Furthermore, all the basic concepts or variables of thermodynamics can be understood more directly or physically within the new framework, in contrast to the too much abstract or mathematical nature of the explanations adopted in current thermodynamics texts.
