With grave deliberation and unimpeachable rigor, this introductory series endeavors to guide the earnest inquirer through the principle domains of physical law—commencing with the inexorable determinism of mechanics and advancing, with cautious solemnity, through the often inscrutable phenomena of heat, the spectral ambiguities of light, and the ominous twin forces of electricity and magnetism. Each lecture, meticulously prepared, is not content to confine its revelations to the arid refuge of theory; experiments and demonstrations shall, under prudent supervision, render the invisible visible and the intangible manifest, that students may glimpse, however fleetingly, the profound and often unsettling order beneath perceived reality.
