Lewontin, Rose and Kamin discuss the different levels at which atoms assemble to make molecules, molecules assemble to make cells and so on: «as one moves up a level the properties of each larger whole are given not merely by the units of which it is composed but of the organizing relations between them... these organizing relationships mean that the properties of matter relevant at one level are just inapplicable at other levels» (NG 278).

Each hydrogen atom, made up of just a single proton and electron, can be found in two slightly different states: a higher energy state in which the electron and proton essentially spin in the same direction, and a lower energy state in which they spin in opposite directions.
