Chemistry, Physics, Locomotion

'Chemistry', as a condition of simultaneity obtaining between several components, would seem to be distinct from 'Physics', the components of which, i. e. Cause and Effect, are successive.  However, some Chemic events, e. g. the melting of ice by the application of hear, involve causal successiveness, while Kant's Category of Community, from which he derives Newton's Third Law of Motion, entails the simultaneity of causal relations, so the fundamental distinction between Chemistry and Physics is not a temporal one.  Rather, among their modern versions, at least, the difference is a spatial one--while the primary theme of Newtonian Physics is Locomotion, Chemic events are not essentially constituted by such change of location, i. e. even insofar as they involve microscopic motions, distance is not a germane factor in them.  So, on the basis of that spatial feature, the two Sciences are mutually independent.
