| law | A scientific principle that invariably holds true under specificconditions, for instance, the law of magnetism states that likemagnetic poles repel one another, while opposite poles attract. See: hypothesis, theory. (09 Oct 1997) |

Haeckel that individuals in their embryonic development pass through stages similar in general structural plan to the stages their species passed through in its evolution; more technically phrased, the theory that ontogeny is an abbreviated recapitulation of phylogeny. Synonym: biogenetic law, law of biogenesis, Haeckel's law, law of recapitulation. (05 Mar 2000) |

| law of contiguity | When two ideas or psychologically perceived events have once occurred in close association they are likely to so occur again, the subsequent occurrence of one tending to elicit the other; this law figures prominently in modern theories of conditioning and learning. (05 Mar 2000) |

| law of denervation | When a structure is denervated, its irritability to certain chemical agents is increased; e.g., the greater sensitivity of the pupil to acetylcholine after section and degeneration of the third nerve, and of the nictitating membrane to adrenaline after excision of the superior cervical ganglion. (05 Mar 2000) |
| law of excitation | A motor nerve responds, not to the absolute value, but to the alteration of value from moment to moment, of the electric current; i.e., rate of change of intensity of the current is a factor in determining its effectiveness. Synonym: Du Bois-Reymond's law. (05 Mar 2000) |
| law of gravitation | The attractive force between any two bodies is proportional to the product of their masses, and inversely proportional to the square of the distance between their centres. Synonym: law of gravitation. (05 Mar 2000) |
| law of independent assortment | Different hereditary factors assort independently when the gametes are formed; traits at linked loci are an exception. Synonym: Mendel's second law. (05 Mar 2000) |
| law of initial value | The direction of response of a body function to any agent depends to a large degree on the initial level of that function. Synonym: law of initial value. (05 Mar 2000) |
| law of intestine | Contraction above and relaxation below a stimulated point in the intestine. Synonym: law of intestine. (05 Mar 2000) |
| law of isochronism | A nerve and the muscle which it innervates have the same chronaxie values. (05 Mar 2000) |
| law of mass action | <chemistry> This law states that the rate of a given chemical reaction is proportional to concentration of the reactants. (09 Oct 1997) |
| Abbe's law of limiting resolution | <physics> For a periodic structure of units separated by distance d and obliquely illuminated by the unrefracted ray and one of the two diffracted rays (extremely oblique illumination). Abbe applied the law of diffraction: d = 0.5 lambda /NA, where: lambda = wavelength of the monochromic light or shortest of mixed wavelengths NA = the limiting numerical aperture (NA) of objective or condenser. (05 Aug 1998) |

| all or none law | Consistently total response to any effective stimulus. Synonym: all or none law. (05 Mar 2000) |
| American Law Institute formulation | Used in certain jurisdictions to determine criminal responsibility in legal proceedings. See: criminal insanity. (05 Mar 2000) |
| American Law Institute rule | A test of criminal responsibility (1962): "a person is not responsible for criminal conduct if at the time of such conduct as a result of mental disease or defect he lacks substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law." (05 Mar 2000) |
| Ampere's law | <physics> General equation in electromagnetism relating the magnetic field and the currents generating it. The various forms of the equation can be found in an introductory electromagnetism text. (09 Oct 1997) |
| Angstrom's law | A substance absorbs light of the same wavelength as it emits when luminous. (05 Mar 2000) |
| Arndt's law | An obsolete law stating that weak stimuli excite physiologic activity, moderately strong ones favour it, strong ones retard it, and very strong ones arrest it. (05 Mar 2000) |
| Arrhenius law | The theory of electrolytic dissociation (1887) that became the basis of our modern understanding of electrolytes: in an electrically conductive solution (e.g., acid, base, or salt), free ions are present before electrolysis, and the proportion of molecules dissociated into ions can be calculated from measurements of electrical conductivity as well as of osmotic pressure. Synonym: Arrhenius law. (05 Mar 2000) |
| Avogadro's law | Equal volumes of gases contain equal numbers of molecules, the conditions of pressure and temperature being the same. Synonym: Ampere's postulate, Avogadro's hypothesis, Avogadro's postulate. (05 Mar 2000) |
| Baer's law | The general organ characteristics found in all members of a group appear earlier in embryogenesis than the special organ characteristics that distinguish specific members of the group; this law is the predecessor of the recapitulation theory. (05 Mar 2000) |
| Baruch's law | The effect of any hydriatric procedure is in direct proportion to the difference between the temperature of the water and that of the skin; when the temperature of the water is above or below that of the skin the effect is stimulating; when the two temperatures are the same the effect is sedative. (05 Mar 2000) |
| beer-lambert law | The equation A=ECL, where A is the absorbance at a given wavelength of light, E is the molar extinction coefficient, C is the concentration of the molar solution, and L is the length of the light path. In words, the equation means that the concentration of a substance in moles is proportional to the absorption of a given wavelength of light by a solution of the substance. The equation is used in the study of spectroscopy. (09 Oct 1997) |
| Beer's law | The intensity of a colour or of a light ray is inversely proportional to the depth of liquid through which it is transmitted; it is concluded that the absorption is dependent upon the number of molecules in the path of the ray. Compare: Beer-Lambert law. (05 Mar 2000) |
| Behring's law | Parenteral administration of serum from an immunised person provides a relative, passive immunity to that disease (i.e., prevents it, or favourably modifies its course) in a previously susceptible person. (05 Mar 2000) |
| Bell-Magendie law | The ventral spinal roots are motor, the dorsal are sensory. Synonym: Bell-Magendie law, Magendie's law. (05 Mar 2000) |
