Free-radical theory — The free radical theory of aging states that organisms age because cells accumulate free radical damage over time. In general, a free radical is any atom or molecule that has a single unpaired electron in an outer shell. While a few free radicals … Wikipedia
Free electron model — In three dimensions, the density of states of a gas of fermions is proportional to the square root of the kinetic energy of the particles. In solid state physics, the free electron model is a simple model for the behaviour of valence electrons in … Wikipedia
