Langevin dynamics

Langevin dynamics is like a way for scientists and mathematicians to figure out how things will move in a very complex way. All things in the universe are made up of tiny, tiny pieces called atoms and when those atoms move around and bump into each other, they can create movements and changes. Langevin dynamics is one way to figure out how all those pieces move, like a set of rules. It can be used to figure out how things will move, like how air flows or how a ball moves when it gets dropped.
