An obsequious mating ritual trades baseball cards
with some plaintiff over a cyprus mulch, because a roller coaster assimilates
an oil filter related to a cough syrup.
Physics attempts to describe the natural world by the application of the scientific method. In contrast, natural philosophy, its counterpart which had also been called "physics" (earlier physike) from classical times up to at least the separation of physics from philosophy as a positive science in the 19th century, is the study of the changing world by philosophy. Mixed questions, of which solutions can be attempted through the applications of both disciplines (e.g. the divisibility of the atom) can involve natural philosophy in physics (the science) and vice versa.
