study of the elements and compounds that can be made from them; emotional connection between people, suitability
[from Greek chemeia
] An ancient art or science relating to the extraction of medicinal juices from plants, or of metals from their earths, or the transmutation of physical elements, as of base metals into gold, the preparation of elixirs, and other things usually connected with alchemy, from which modern chemistry is a derivative along specialized line.
In The Secret Doctrine
chemistry is mentioned as being, together with biology, one of the magicians of the future, especially in its form of chemical physics, when it is no longer the mechanistic science into which it has degenerated. "In Esoteric Philosophy, every physical particle corresponds to and depends on its higher noumenon
-- the Being to whose essence it belongs; and above as below, the Spiritual evolves from the Divine, the psycho-mental from the Spiritual -- tainted from its lower plane by the astral -- the whole animate and (seemingly) inanimate Nature evolving on parallel lines, and drawing its attributes from above as well as from below" (SD 1:218).
\chem"is*try\ (k&ebreve;m"&ibreve;s*tr&ybreve;; 277), n. [from chemist. see alchemy.] 1.
that branch of science which treats of the composition of substances, and of the changes which they undergo in consequence of alterations in the constitution of the molecules, which depend upon variations of the number, kind, or mode of arrangement, of the constituent atoms. these atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained. chemistry deals with the changes in the composition and constitution of molecules. see atom, molecule.
note: historically, chemistry is an outgrowth of alchemy (or alchemistry), with which it was anciently identified. 2.
an application of chemical theory and method to the consideration of some particular subject; as, the chemistry of iron; the chemistry of indigo. 3.
a treatise on chemistry.
note: this word and its derivatives were formerly written with y, and sometimes with i, instead of e, in the first syllable, chymistry, chymist, chymical, etc., or chimistry, chimist, chimical, etc.; and the pronunciation was conformed to the orthography.

Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry is chiefly concerned with atoms and molecules and their interactions and transformations, for example, the properties of the chemical bonds formed between atoms to create chemical compounds. As such, chemistry studies the involvement of electrons and various forms of energy in photochemical reactions, oxidation-reduction reactions, changes in phases of matter, and separation of mixtures. Preparation and properties of complex substances, such as alloys, polymers, biological molecules, and pharmaceutical agents are considered in specialized fields of chemistry.
