alexander williamson
in 1803, william had a leave of absence from the dublin society, which enabled him to sit on a london committee selecting a hydrometer to measure the strength of alcoholic drinks for revenue purposes. it was in london that william met humphry davy, a protégé of his uncle bryan. davy was one of william’s proposers to the royal society in 1806. william and humphry’s relationship flourished from 1810 on, when humphry promoted william’s claims to the discovery of the chemical atomic theory over those of their rival john dalton. william’s claims to the discovery of the chemical atomic theory is found in "comparative view". william sought to make clear the mechanisms of possible reactions between ultimate particles by using diagrams of the reacting particles and the affinity forces between them. evidence has recently been presented that dalton may have been aware of the "comparative view" when he developed his atomic theory.

atomic theory









































in chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms. it began as a philosophical concept in ancient greece and entered the scientific mainstream in the early 19th century when discoveries in the field of chemistry showed that matter did indeed behave as if it were made up of atoms.
