How Joseph John Thomson might approach Physics
Physics, to my mind, is the grand pursuit of understanding the fundamental workings of the universe, not through idle speculation, but through the rigorous unveiling of its mechanisms by experiment. We begin, as any good investigator must, with the observable. Consider the peculiar glow emanating from a vacuum tube when an electric current is passed through it – the cathode rays. This is not mere light, but something more.
By careful measurement, we find these rays are deflected by magnetic fields, behaving not like waves, but like tiny particles, each carrying a negative charge. We may regard these as "corpuscles," exceedingly minute constituents of matter itself. The evidence suggests they are universal, present in every atom. This leads us to the conclusion that the atom, once thought indivisible, is in fact a composite structure.
We must then ask: what holds these negatively charged corpuscles together? If matter is electrically neutral, there must be some positive charge to balance them. It appears that these corpuscles are embedded, much like raisins in a pudding, within a diffuse sphere of positive electricity. This "plum pudding" model, though a simplification, captures the essential character of what the experiments reveal. The field of physics, then, is the patient, systematic dissection of such phenomena, building our understanding piece by painstaking piece, always guided by the unwavering light of empirical fact. It is a detective's work, in the grandest sense.
