Why do we need to look at things at a microscopic level?
Overall picture given by chatGPT Molecular dynamics (MD) simulation is a computational method for studying the physical movements of atoms and molecules. It involves using computer algorithms to integrate the equations of motion for a system of interacting particles, in order to predict the evolution of the system over time.
In an MD simulation, the positions, velocities, and forces on each particle are calculated at discrete time steps, typically on the order of femtoseconds (10^-15 seconds).
