BOSS (molecular mechanics)
Encyclopedia
BOSS is a general-purpose molecular modeling program that performs molecular mechanics
calculations, Metropolis Monte Carlo
statistical mechanics simulations, and semiempirical AM1, PM3
, and PDDG/PM3 quantum mechanics
calculations. The molecular mechanics calculations cover energy minimizations, normal mode analysis and conformational searching with the OPLS
force fields. BOSS is developed by Prof. William L. Jorgensen
at Yale University

Quantum mechanics
Quantum mechanics, also known as quantum physics or quantum theory, is a branch of physics providing a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. It departs from classical mechanics primarily at the atomic and subatomic...
