Argues that previous definitions of work and heat are inappropriate. Presents new definitions that are formulated using experimental quantities, claiming that they apply equally well to reversible and irreversible processes. Indicates some of the problems with earlier definitions and applies the new definitions to the First Law of thermodynamics.…

Draws a distinction between the terms "heat and work" and "energy" in terms of the teaching of thermodynamics. Gives examples using enthalpy and constant pressure processes, free energy and spontaneity, and free energy and available mechanical energy. Concludes that there is no thermodynamic role for the terms "heat"…

This paper examines how the revolution in human thinking, with the smaller revolution in astronomy begun by Nicolus Copernicus, has plunged science educators into the new Age of Information. Examples which illustrate this development and change in human thinking (from Copernicus' time to the present) are provided from such disciplines as…

Discusses some of the misconceptions commonly held suggesting that mixing ideal gases causes an increase in entropy. Argues that the combining processes and resulting total pressure have absolutely nothing to do with the mixing itself. (TW)

This paper suggests that present-day curriculum, based on Newtonian thought, has been rendered obsolete by the holistic and interactive "post-modern" world view based on quantum physics, nonlinear mathematics, general systems theory, and Ilya Prigogine's nonequilibrium thermodynamics. The Newtonian world view, which is linear and…

Applies the concept of entropy to aging, evolving systems, inanimate systems such as corporations, and structural complexity for classroom teaching. Presents many mathematical expressions as well as explanations. Lists 37 references. (YP)

Presents an approach to combine the empirical approach of classical thermodynamics with the structural approach of statistical mechanics. Topics covered include dynamical foundation of the first law; mechanical work, heat, radiation, and the first law; thermal equilibrium; thermal processes; thermodynamic probability; entropy; the second law;…

The evolution of ideas about the concept of chaos is surveyed. Discussed are chaos in deterministic, dynamic systems; order in dissipative systems; and thermodynamics and irreversibility. Included are logistic and bifurcation maps to illustrate points made in the discussion. (CW)

Discussed is the idea that energy is the cause of change. This idea, going back to early cognitive development, means that the teaching of energy needs to confront how, thermodynamically, people can perform actions. The change in energy caused by differences is emphasized. (KR)

Describes Ocean Thermal Energy Conservation (OTEC) as a method for exploiting the temperature difference between warm surface waters of the sea and its cold depths. Argues for full-scale demonstrations of the technique for producing energy for coastal regions. (TW)
