Estimation of the Size of Oil Molecules

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.
