On the interrelation between the methodologies of chemistry and physics

Resumo

Aspects of the methodology and language of chemistry and physics are discussed. Chemistry defines the chemical properties of any substance from the results of its interaction with other substances using the logic of relations. Therefore, describing the properties of substances means using sets of different ideas, including ones that are opposite in meaning. Consequently, depending on the nature of reagents with respect to which properties are established, substances show chemical dualism. This dualism was established in chemistry long before the discovery of wave–particle dualism, to understand which N. Bohr proposed the complementarity principle in 1927. The methodology of natural sciences corresponds to the principle of complementarity and the need to use it to understand the world and record the results in the linguistic reality of several languages.
