    Einstein’s Principle of Equivalence and the Heuristic Significance of General Covariance

    The philosophy of physics literature contains conflicting claims on the heuristic significance of general covariance. Some authors maintain that Einstein's general relativity distinguishes itself from other th...

    Introduction: A Critique of Minkowski Spacetime

    Cosgrove lays out the overall task of the book, which is to subject the concept of Minkowski spacetime in relativity theory to a comprehensive critique from a conceptual and historical perspective. Cosgrove fi...

    Desedimentation of Minkowski Spacetime

    Cosgrove here applies the historical findings of the previous two chapters to the concept of Minkowski spacetime. While the Minkowski spacetime interval is often called a “generalization” of the Pythagorean Th...

    Relativity and Time

    Cosgrove in this concluding chapter addresses the status of time in relativity theory in light of the critique of Minkowski spacetime. Cosgrove argues that although neither absolute simultaneity nor becoming o...

    Special Relativity and Spacetime

    In this chapter Cosgrove subjects the concept of Minkowski spacetime to critique in three principal respects: (1) the theory of spacetime articulates no clear meaning to the concept of a single continuum of sp...

    The Historical Sense-Structure of Modern Algebraic Physics

    The assimilation of Cartesian algebra into mathematical physics met with significant opposition, engendered by basic issues of physical intelligibility. In this chapter Cosgrove considers more closely those hi...

    Minkowski Spacetime and General Relativity

    Cosgrove demonstrates both that Minkowski spacetime taken as a physical concept is unnecessary to general relativity and that the mathematical apparatus of four-vectors is superfluous as well. He addresses the...

    Minkowski’s “Space and Time”

    This chapter is a critical reading of the published version of Minkowski’s 1908 Cologne address, in which the concept of four-dimensional spacetime was publically unveiled. Cosgrove places Minkowski’s endeavor...

    The Historical Sense-Structure of Symbolic Algebra

    Cosgrove shows that the conceptual obstacles to the assimilation of algebra into mathematical physics were successfully overcome from the late seventeenth through the eighteenth century, yielding a new mathema...
