Natura Simplex : Conceptual Physics II

We explore the fundamental nature of matter through the historical debate between energism and atomism, which shaped physics in the late nineteenth century.We trace the main stages of this debate, from attempts to explain matter in terms of energy to the experimental recognition of atoms and the discovery of their internal structure. Experimental evidence for atoms established the reality of matter’s microscopic structure, without settling the question of whether its constituents are truly fundamental. We examine the possibility that matter and light correspond to different forms of organization of the same underlying reality, whose dynamics could give rise to distinct physical structures. The electron serves as a privileged case study : its experimentally established properties are considered alongside an interpretation based on the coherent organization of phase. This approach distinguishes the elementary status of a particle within a physical theory from its possible fundamental nature, and raises questions about the status of the many particles identified by physics.
