| 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) |

| 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 | 1. A fermented liquor made from any malted grain, but commonly from barley malt, with hops or some other substance to impart a bitter flavor. Beer has different names, as small beer, ale, porter, brown stout, lager beer, according to its strength, or other qualities. See Ale. 2. A fermented extract of the roots and other parts of various plants, as spruce, ginger, sassafras, etc. Small beer, weak beer; (fig) insignificant matters. "To suckle fools, and chronicle small beer." Origin: OE. Beor, ber, AS. Beor; akin to Fries. Biar, Icel. Bjrr, OHG. Bior, D. & G. Bier, and possibly E. Brew. 93, See Brew. Source: Websters Dictionary (01 Mar 1998) |
| Beer, August | <person> German physicist, 1825-1863. See: Beer-Lambert law, Beer's law. (05 Mar 2000) |

| beer heart | <cardiology, pathology> A weakness of the cardiac muscle which is seen in some chronic alcoholics, may be related to a thiamin deficiency or occur for unknown reasons. Origin: Gr. Pathos = disease (27 Sep 1997) |
| Beer's knife | A triangular knife with a sharp point and one sharp edge, formerly used for incision for cataract. (05 Mar 2000) |
| 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.

| 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."

| 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) |
| Beer's law |
the ability of a penetrant to yield an indication depends primarily on its ability to fluoresce as a very thin film. The performance of penetrants based on the physical constraints of the dyes can be predicted using Beer's Law equation. This equation does not hold true when very thin layers are involved but works well to establish general relationships between variables.
