| Newton's law | 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) |

| newton | Derived unit of force in the SI system, expressed as meters-kilograms per second squared (m-kg-s-2); equivalent to 105 dynes in the CGS system. Abbreviation: N Origin: I. Newton (05 Mar 2000) |
|---|---|
| newton-meter | A unit of the MKS system, expressed as energy expended, or work done, by a force of 1 newton acting through a distance of 1 meter; equal to 1 joule = 107 ergs. (05 Mar 2000) |
| Newton's disk | A disk on which are seven coloured sectors, each occupying proportionally the same space as the corresponding primary colour in the spectrum; when the disk is rapidly rotated it appears white. (05 Mar 2000) |
| Newton's interference colours | <microscopy> Newton's series of colours by interference results when two wave-trains of white light meet. For some wavelengths (colours) there will be destructive interference (darkness) but for other wavelengths there will be reinforcement (colour). They are most frequently observed in very thin films, only wavelengths thick, for example, oil on water. The interference is caused by partially reflected light from the interfaces. Newton's series of colours appears in sequence in the Michel-Levy chart. (05 Aug 1998) |
| Newton, Sir Isaac | <person> English physicist, 1642-1727. See: newton, newtonian aberration, Newtonian constant of gravitation, newtonian flow, newtonian viscosity, Newton's disk, Newton's law. (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. (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) |
