Physics and Chemistry: Commensurate or Incommensurate Sciences?

  • Chapter
The Invention of Physical Science

Part of the book series: Boston Studies in the Philosophy of Science ((BSPS,volume 139))

Abstract

In the preface to this Introduction to Chemical Physics (1939), the American physicist and co-founder of quantum chemistry John C. Slater wrote the following:

It is probably unfortunate that physics and chemistry ever were separated. Chemistry is the science of atoms and of the way they combine. Physics deals with the interatomic forces and with the large-scale properties of matter resulting from those forces. So long as chemistry was largely empirical and non-mathematical, and physics had not learned how to treat small-scale atomic forces, the two sciences seemed widely separated ... Now that statistical mechanics has led to quantum theory and wave mechanics, with its explanations of atomic interactions, there is really nothing separating them any more .... [However,] for want of a better name, since Physical Chemistry is already preempted, we may call this common field Chemical Physics.1

It is a pleasure to acknowledge research support for this study from the National Endowment for the Humanities and the University of Oklahoma. I am indebted, too, to students and colleagues in my seminar at Harvard University during the spring of 1988; to the Bodleian Library at Oxford University; and to comments on an earlier draft from Robert Nye. The basic problem-set of this essay is one to which I was first introduced by Erwin Hiebert.
