This paper is the first part of a three-part project ‘How the principle of energy conservation evolved between 1842 and 1870: the view of a participant’. This paper aims at showing how the new ideas of Mayer and Joule were received, what constituted the new theory in the period under study, and how it was supported experimentally. A connection was found between the new theory and thermodynamics which benefited both of them. Some considerations are offered about the desirability of taking (...) a historical approach to teaching energy and its conservation. (shrink)

In what follows I use the term ‘academic engineering’ to describe the teaching of engineering within a university or college of higher education: specifically, this differentiates an institutional teaching framework from the broader assimilation of engineering working practices in nineteenth-century Britain by the then standard method of apprenticeship or pupillage, and from the practice of engineering as a profession. The growth of academic engineering, both in terms of student numbers and the variety of courses, profoundly influenced the structure of what (...) we might call ‘practical engineering’, the status of engineering as a profession searching for recognition within society, and the corporate relationship between engineers and places of higher education. These are issues which I will only touch on here. (shrink)
