In this research, an educational approach to the concept of energy is proposed. It is based on the history of physics. In 1854 Hermann Hemlholtz gave a popular lecture on the recent discovery that energy is conserved. Such lecture is used as a guide to introduce the pupils within several nuances of this concept. Not much mathematics is used, so…

At first almost ignored and unread, Sadi Carnot's analysis of heat engines--published 150 years ago--contained ideas and methods that were developed later by Clausius and Thomson. Carnot's ideas and their influence on later science are discussed. (Author/RH)

Presents the history surrounding the evolution of the second law of thermodynamics. Discusses Sadi Carnot's contributions, but also refers to those by Clapeyron, Thomson, Joule, Clausius, and Boltzman among others. (RR)

The classical vacuum of physics is not empty, but contains a distinctive pattern of electromagnetic fields. Discovery of the vacuum, thermal spectrum, classical electron theory, zero-point spectrum, and effects of acceleration are discussed. Connection between thermal radiation and the classical vacuum reveals unexpected unity in the laws of…

Briefly mentions pre-19th century ideas and discusses the contributions of Mohr, Seguin, Mayer, Grove, Colding, Joule and Helmholtz and the controversies regarding priority including Tyndall's involvement in one of them. Mentions the tension between philosophical and practical modes of thought in 19th century science. Includes portraits. (GH)

Presents a chronicle of the life of American born Benjamin Thompson. His private life as well as descriptions of his scientific experiments are discussed. (CP)

This historical survey describes the contributions made to the field of physics by the National Bureau of Standards since its inception in 1901. Four broad areas are emphasized: nuclear physics, thermal physics (including cryogenics), spectroscopy and fundamental constants. (BT)

Analyzes students' misunderstanding of basic thermodynamic concepts on historical grounds. Finds that the persistence of some ideas from the caloric model are reinforced by magnitude names and unit definitions that were brought up at the early stages of thermodynamic development. Explores the failure of many popular textbooks to make a clear…

Gives a brief descriptive review of the life of Albert Einstein, his scientific papers and his valuable contributions to physics. (BA)

Presents notes on three physics experiments on (1) light and lenses, (2) determination of the pVT surface of a freon, and (3) use of an eyepiece with microscopes and telescopes. (RH)

The foundation of science, and of thermodynamics in particular, can be developed cogently and without arbitrariness. The goal of science, description of nature, is externally given; it requires a set of basic concepts as indispensable tools. Mathematics has no similar externally given goal. (Author/TS)

Surveys the major areas of discovery in physics for the past two hundred years. Attempts to predict future discoveries from analyses of past trends. (CP)

Traces the development of thermodynamics in physics, focusing on a strategy which enables students to grasp in a limited time and by means of simple calculus the main implications of the second law essential for everyday life (understanding operation of heat engines, refrigerators, heat pumps, district heating, and energy degradation). (JN)

Inquires into the individual names and dates which are associated with the various perfect gas laws on the basis of published and historically researched works. Indicates the presence of eight features in giving a scientist credit for a scientific discovery. (CC)

The common definition is shown to be false. A modern definition must be based on the first and second laws of thermodynamics and in terms of a set of algebraic expressions written in such a way that their sum does not change when a system is isolated. (DF)
