| newtonian aberration | When using white light through a lens system, it is inevitable that different wave lengths (colours) are brought to a focus at slightly different points. As a consequence, there are chromatic aberations in the image, good microscope objectives are therefore corrected for this at two wave lengths (achromats) or at three wave lengths (apochromats), as well as for spherical aberration.

| newtonian | Of or pertaining to Sir Isaac Newton, or his discoveries. Newtonian philosophy, the philosophy of Sir Isaac Newton; applied to the doctrine of the universe as expounded in Newton's "Principia," to the modern or experimental philosophy (as opposed to the theories of Descartes and others), and, most frequently, to the mathematical theory of universal gravitation. <astronomy> Newtonian telescope, a reflecting telescope, in which rays from the large speculum are received by a plane mirror placed diagonally in the axis, and near the open end of the tube, and thrown at right angles toward one side of the tube, where the image is formed and viewed through the eyeplace. Newtonian theory of light. See Note under Light. Source: Websters Dictionary (01 Mar 1998) |

| Newtonian constant of gravitation | A universal constant relating the gravitational force, f., attracting two masses, m1 and m2, toward each other when they are separated by a distance, r, in the equation: f = G(m1m2/r2); it has the value of 6.67259 × 10-8 dyne cm2 g-2 = 6.67259 × 10-11 m3 kg-1 s-2 in SI units.

| newtonian flow | The type of flow characteristic of a newtonian fluid. (05 Mar 2000) |
| newtonian fluid | A fluid in which flow and rate of shear are always proportional to the applied stress; such fluid precisely obeys Poiseuille's law. Compare: non-newtonian fluid. (05 Mar 2000) |
| newtonian viscosity | The viscosity characteristics of a newtonian fluid. (05 Mar 2000) |
| non-Newtonian fluid | <chemistry, physics> A fluid in which the viscosity varies depending upon the shear stress. The effect can arise because of alignment of nonspherical molecules as flow is established or because of suspended deformable particles as in blood. It relates to a fluid in which flow and rate of shear are not always proportional to the applied stress and which does not obey Poiseuille's law. See: anomalous viscosity, Fahraeus-Lindqvist effect, Bingham plastic. Compare: newtonian fluid. (21 Jun 2000) |
| aberration | 1. <ophthalmology> Any error that results in image degradation. Such errors may be chromatic, spherical, astigmatic chromatic, distortion, or curvature of field: and can result from design or execution, or both. 2. <physics> Failure of an optical or electron-optical lens to produce exact geometrical (and chromatic) correspondence between an object and its image. In a video camera tube or cathode-ray tube, aberrations are when the (electrostatic or electromagnetic) lens does not bring the electron beam to sharply focused points uniformly on the target or screen, or to correct geometrical positions, as the beam is deflected. 3. <zoology> A term which, if used to denote a number of individuals within a species, unequivocally signifies infrasubspecific rank. See: aberration, chromatic, aberration, spherical. (09 Jan 1998) |
| aberration, chromatic | <optics> A defect in a lens or optical system due to the greater refraction of shorter wavelengths over that of loner ones at a lens surface. Hence the focal length of a simple lens is shorter for blue than for red rays. This dispersion of the wave-lengths will cause colour fringes in the image field of a lens with such an aberration. (05 Aug 1998) |
| aberration, spherical | <optics> A lens defect whereby image forming rays of one colour, passing through the outer zones of a lens come to focus at a different distance from the lens than do those of more central rays. With a simple spherical (or plano-spherical) lens the outer rays always meet the axis closer to the lens than do more central rays and the lens is uncorrected or undercorrected. When the reverse is true the lens has been overcorrected. (05 Aug 1998) |
| ventricular aberration | Abnormal intraventricular conduction of a supraventricular beat, especially where surrounding beats are normally conducted. Synonym: ventricular aberration. (05 Mar 2000) |
| mental aberration | Disturbed thought or behaviour that connotes a psychological or psychiatric impairment. See: delusion. (05 Mar 2000) |
| meridional aberration | An aberration produced in the plane of a single meridian of a lens. (05 Mar 2000) |
| chromatic aberration | When using white light through a lens system, it is inevitable that different wave lengths (colours) are brought to a focus at slightly different points. As a consequence, there are chromatic aberations in the image, good microscope objectives are therefore corrected for this at two wave lengths (achromats) or at three wave lengths (apochromats), as well as for spherical aberration. (18 Nov 1997) |
| chromosomal aberration | Any abnormality of a chromosome's number or structure. (09 Oct 1997) |
| chromosome aberration | Any deviation from the normal number or morphology of chromosomes; also the phenotypic consequences thereof. (05 Mar 2000) |
