>but atoms are on a discreet lattice locations This is where it starts getting interesting. Where is the "location" of an atom? Is it the nucleus? Is it the electrons? Is it just the electrons which are localized to particular nuclei? Etc. Typically the "location" has some uncertainty, both from thermal jitter and from the nature of orbitals as probability densities.
