Atomic theory | 🗖 nosplit | ↑ parent "Chemistry" | 66, 1, 143
Theory that atoms exist, i.e. matter is not continuous.
Evidence:
- Brownian motion mathematical analysis in 1908
- X-ray crystallography: it sees crystal latices
- scanning tunnelling microscope: it sees individual atoms for Christ's sake, what else do you want?
