Recent experimental observations of nucleation, the point where a solid first forms, contradict the predictions of classical nucleation theory. As a result uncertainty exists over a number of possible mechanisms for the formation of crystals from liquids. Now a team of researchers have used transmission electron microscopy to observe the formation of the mineral calcium carbonate from start to finish, providing evidence of several different pathways involved in crystallization…..
