| microscope mirror | <microscopy> Usually plane on one side and concave on the other. The flat side is generally used unless the objective is of very low power and there is no condenser. The mirror should be so mounted that the concave side can be focused on the specimen. (05 Aug 1998) |
| mirror | 1. A looking-glass or a speculum; any glass or polished substance that forms images by the reflection of rays of light. "And in her hand she held a mirror bright, Wherein her face she often viewed fair." (Spenser) 2. That which gives a true representation, or in which a true image may be seen; hence, a pattern; an exemplar. "She is mirour of all courtesy." (Chaucer) "O goddess, heavenly bright, Mirror of grace and majesty divine." (Spenser) 3. <zoology> See Speculum. <zoology> Mirror carp, a domesticated variety of the carp, having only three or fur rows of very large scales side. Mirror plate. A flat glass mirror without a frame. Flat glass used for making mirrors. Mirror writing, a manner or form of backward writing, making manuscript resembling in slant and order of letters the reflection of ordinary writing in a mirror. The substitution of this manner of writing for the common manner is a symptom of some kinds of nervous disease. Origin: OE. Mirour, F. Miroir, OF. Also mireor, fr. (assumed) LL. Miratorium, fr. Mirare to look at, L. Mirari to wonder. See Marvel, and cf. Miracle, Mirador. Source: Websters Dictionary (01 Mar 1998) |
| mirror effect | <physics> A charged particle travelling into an increasing magnetic field will (if the field becomes strong enough) reverse direction and be reflected back. This is a direct result of the adiabatic invariance of the magnetic moment. Plasmas can be confined by devices which utilise this effect. The effect also occurs in some toroidal plasmas, since the toroidal magnetic field is stronger on the inboard side than on the outboard side, in this case it gives rise to so-called neoclassical effects. The strength of the mirror is determined by the mirror ratio. (09 Oct 1997) |
| mirror, first or front surface | <microscopy> An optical mirror on which the reflecting surface is applied to the front surface of the mirror instead of to the back, that is, to the first surface of incidence. (05 Aug 1998) |
| mirror image | A representation of an object or part thereof as its reflected image in a glass mirror. (05 Mar 2000) |
| mirror-image cell | A cell whose nuclei have identical features and are placed in the cytoplasm in similar fashion, a binucleate form of Reed-Sternberg cell often found in Hodgkin's disease; the twin nuclei are disposed in relation to an imaginary plane between them like a single nucleus together with its image in a mirror. (05 Mar 2000) |
| mirror image dextrocardia | Perfect right to left congenital reversal of the heart sometimes with other congenital abnormalities, sometimes normal except for position. (05 Mar 2000) |
| mirror speech | A reversal of the order of syllables in a word, analogous to mirror writing. (05 Mar 2000) |
| mirror-writing | Writing backward, from right to left, the letters appearing like ordinary writing seen in a mirror. Synonym: retrography. (05 Mar 2000) |
