For example, you can use Molecular Dynamics simulations of atoms and their interactions over time in order to compute properties of the material through the statistical mechanics magic that is the Boltzmann constant, which bridges the microscopic with the macroscopic. That's how in University I got to play with melting high level nuclear waste in molten potassium and lithium salts without having to actually physically handle any of that yucky stuff.
