| principle of inertia | In psychoanalysis, the impulse to redramatise or reenact earlier emotional experiences or situations. Synonym: principle of inertia. (05 Mar 2000) |
| proximate principle | In chemistry, an organic compound that may exist already formed as a part of some other more complex substance (e.g., various sugars, starches, and albumins). Synonym: organic principle. (05 Mar 2000) |
| Huygens' principle | Used in ultrasound technology; the principle that any wave phenomenon can be analyzed as the sum of many simple sources properly chosen with regard to phase and amplitude. (05 Mar 2000) |

| founder principle | The conditional probabilities of the frequencies of a set of genes at any future date depend on the initial composition of the founders of the population and have in general no tendency to revert to the composition of the population from which the founders were themselves derived.

| Le Chatelier's principle | If external factors such as temperature and pressure disturb a system in equilibrium, adjustment occurs in such a way that the effect of the disturbing factors is reduced to a minimum. Synonym: Le Chatelier's principle. (05 Mar 2000) |
| low flow principle | A principle based on the observation that animals can survive prolonged vena caval occlusion without sequelae: if blood from the azygos vein alone is permitted to enter the heart, patients are perfused during cardiac and pulmonary bypass at flows much less than the normal resting cardiac output. Synonym: low flow principle. (05 Mar 2000) |

| activation energy | <chemistry> The amount of energy (expressed in joules) that is needed to convert all the molecules in one mole of a reacting substance from a ground state to the transition state. (06 May 1997) |
| binding energy | <chemistry, radiobiology> The binding energy of a nucleus is the minimum energy required to dissociate it into its component neutrons and protons. Neutron or proton binding energies are those required to remove a neutron or proton, respectively, from a nucleus. Electron binding energy is that required to remove an electron from an atom or a molecule. (16 Dec 1997) |
