Description

One of the important questions in atomic physics is the question of the size of the atom. The study of the size of molecules provides experimentally easier access on a manageable magnitude. Experiment C1.1.3.2 uses simple means to estimate the size of molecules from the size of a patch of oil floating on the surface of water.
