This book is about the methods used for unifying different scientific theories under one all-embracing theory. The process has characterized much of the history of science and is prominent in contemporary physics; the search for a "theory of everything" involves the same attempt at unification. Margaret Morrison argues that, contrary to popular philosophical views, unification and explanation often have little to do with each other. The mechanisms that facilitate unification are not those that enable us to explain how or why phenomena behave as they do. The book emphasizes the importance of...

Models as Mediators discusses the ways in which models function in modern science, particularly in the fields of physics and economics. Models play a variety of roles in the sciences: they are used in the development, exploration and application of theories and in measurement methods. They also provide a mechanism for using scientific concepts and principles to intervene in the world. The editors provide a framework that covers the construction and function of scientific models, and explore the ways in which they enable us to learn about both theories and the world. The contributors to the...
