Traditionally in atmospheric science observed nucleation phenomena are described using bulk thermodynamic theories of `Classical Nucleation'. Cloud condensation and droplet equilibrium is typically described using Köhler theory, which captures the equilibrium between finite bulk solution droplets and water vapor. Likewise ice particle formation is understood using varying formulations of classical heterogeneous nucleation theory, whereby small-supercooled foreign particles provide surfaces that lower the free energy barrier to ice formation. However, often the classical theories rely on bulk approximations and empirically determined physical parameters that are difficult to independently ascertain over the range of important atmospheric temperature. I describe experimental and theoretical work that leads us to question some of these assumptions and forces us to strive to identify more precise descriptions of observed phenomena. These fundamental studies are put into the context of climate science and the implications for water availability, heterogeneous chemistry, etc. that lie therein.
