# Computational Physics

> Computational physics develops and applies numerical algorithms to solve physical problems that are analytically intractable, bridging theoretical models and experimental observation. The field encompasses molecular dynamics simulation of atomic and molecular systems, quantum Monte Carlo methods for many-body quantum mechanics, lattice quantum chromodynamics for subatomic physics, finite element and finite difference methods for continuum mechanics and electrodynamics, and large-scale climate and space-weather modelling. The past decade has seen machine learning potentials — neural network force fields trained on ab initio data — transform molecular simulation, enabling nanosecond-scale dynamics of protein-ligand and materials systems at near-quantum accuracy. GPU-accelerated computing and exascale supercomputers are pushing simulation scales to billions of particles. Computational physicists work in condensed matter, particle physics, astrophysics, plasma physics, and beyond. Funding comes from national labs including DOE and CERN, national science foundations, and industrial collaborators in semiconductor design and drug discovery.
