Kinetics of liquids and glasses is discussed from the view point of elementary excitation in energy landscape, based mainly on the results of computer simulation. We present a new phenomenological model to predict glassy dynamics. We then focus on the action of atomic bond being cut or formed, which changes the local topology of atomic connectivity in liquids. The collectivity of topological change is directly connected to the local potential energy landscape.
