Cours donné par Yves Gingras à l’Institute for the History and Philosophy of Science and Technology (IHPST) de l’Université de Toronto au début des années 2000
Description : The object of the course will be to suggest that with the advent of Newtonian physics and its emphasis on the mathematical formulation of physical laws, there has been a gradual transformation of the notion of substance in the wake of more abstract and mathematical formulations of physical phenomena. In order to show this long term movement, we will retrace the development of physics from the point of view of the various hypothetical substances that were taken to constitute the universe and follow their disappearance. We will see how the Cartesian vortex theory was abandoned in the 18th century, how the mechanical ether faced major difficulty at the end of the 19th century and was abandoned in Einstein’s theory of special and general relativity. We will also see that the so-called « wave-particle » duality in quantum mechanics constitute another step toward a formalist view of physics that limits the value of the two major models of physical thinking, namely particles and waves. We will also look at the transformation of the notion of mass from Newton to Einstein. In short, the object of the course is to try to reread the conceptual history of physics from a point of view that makes possible to see long term trends in its development.
