Figure 2 Computational length and time scales. QC stands for quantum chemistry
methods in which the Schr¨odinger equation is solved. MD stands for molecular
dynamics in which classical equations of motion for atomic motion are solved.
Continuum includes thermodynamics, hydrodynamics, continuum mechanics, mi-
cromagnetism in which macroscopic variables describe the system. Statistical me-
chanics supplies the principles by which computations at these different scales are
connected.
