Science of Heat and Thermophysical Studies provides a non-traditional bridging of historical, philosophical, societal and scientific aspects of heat with a comprehensive approach to the field of generalized thermodynamics. It involves Greek philosophical views and their impact on the development of contemporary ideas.
Covered topics include:

. the concept of heat
. thermometry and calorimetry
. early concepts of temperature and its gradients
. non-equilibrium and quantum thermodynamics
. chemical kinetics
. entropy, order and information
. thermal science applied to economy(econophysics), ecosystems, and process dynamics or mesoscopic scales (quantum diffusion)
. importance of energy science and its influence to societal life
