| inverse square law | As applied to point sources, the intensity of radiation diminishes in proportion to the square of the distance from the source. (05 Mar 2000) |

| isodynamic law | For energy purposes, the different foodstuffs may replace one another in accordance with their caloric values when burned in a calorimeter. (05 Mar 2000) |
| Ochoa's law | The content of the X-chromosome tends to be phylogenetically conserved. (05 Mar 2000) |
| ohm's law | <physics> The relationship between the net current and the electric field in a conducting medium. For simple resistors, the voltage equals current times resistance, V = IR. In plasmas the generalised Ohm's Law is a more complex tensor relationship involving the vector current density, the vector for the electric field, and a generalised resistance tensor that relates the two. (09 Oct 1997) |
| Tait's law | An obsolete dictum that an exploratory laparotomy should be performed in every case of obscure pelvic or abdominal disease that threatens health or life. (05 Mar 2000) |
| third law of thermodynamics | <chemistry> The entropy of a perfect crystal at 0 K is zero. (09 Jan 1998) |
| Einthoven's law | In the electrocardiogram the potential of any wave or complex in lead II is equal to the sum of the potentials of leads I and III. Synonym: Einthoven's equation. (05 Mar 2000) |
| Elliott's law | Adrenaline acts upon those structures innervated by sympathetic nerve fibres. (05 Mar 2000) |
| Jackson's law | Loss of mental functions due to disease retraces in reverse order its evolutionary development. (05 Mar 2000) |
| Farr's law | The curve of cases of an epidemic rises rapidly at first, then climbs slowly to a peak from which the fall is steeper than the previous rise. (05 Mar 2000) |
| father-in-law | The father of one's husband or wife; correlative to son-in-law and daughter-in-law. A man who marries a woman having children already, is sometimes, though erroneously, called their father-in-law. Source: Websters Dictionary (01 Mar 1998) |
| zeroeth law of thermodynamics | <chemistry> Two systems in thermal equilibrium with a third are in thermal equilibrium with each other. (09 Jan 1998) |
| Fechner-Weber law | The intensity of a sensation varies by a series of equal increments (arithmetically) as the strength of the stimulus is increased geometrically; if a series of stimuli is applied and so adjusted in strength that each stimulus causes a just perceptible change in intensity of the sensation, then the strength of each stimulus differs from the preceding one by a constant fraction; thus, if a just perceptible change in a visual sensation is produced by the addition of 1 candle to an original illumination of 100 candles, 10 candles will be required to produce any change in sensation when the original illumination was one of 1000 candles. Synonym: Fechner-Weber law, Weber's law. (05 Mar 2000) |
| Koch's law | To establish the specificity of a pathogenic microorganism, it must be present in all cases of the disease, inoculations of its pure cultures must produce disease in animals, and from these it must be again obtained and be propagated in pure cultures. Synonym: Koch's law. (05 Mar 2000) |
| Ferry-Porter law | The critical fusion is directly proportional to the logarithm of the light intensity. (05 Mar 2000) |
