| postulate | 1. Something demanded or asserted; especially, a position or supposition assumed without proof, or one which is considered as self-evident; a truth to which assent may be demanded or challenged, without argument or evidence. 2. <geometry> The enunciation of a self-evident problem, in distinction from an axiom, which is the enunciation of a self-evident theorem. "The distinction between a postulate and an axiom lies in this, that the latter is admitted to be self-evident, while the former may be agreed upon between two reasoners, and admitted by both, but not as proposition which it would be impossible to deny." (Eng. Cyc) Origin: L. Postulatum a demand, request, prop. P. P. Of postulare to demand, prob. A dim. Of poscere to demand, prob. For porcscere; akin to G. Forschen to search, investigate, Skr. Prach to ask, and L. Precari to pray: cf. F. Postulat. See Pray. Source: Websters Dictionary (01 Mar 1998) |
| Ehrlich's postulate | Ehrlich postulated that cells contained surface extensions or side chains (haptophores) that bind to the antigenic determinants of a toxin (toxophores); after a cell is stimulated, the haptophores are released into the circulation and become the antibodies. See: receptor. Synonym: Ehrlich's postulate. (05 Mar 2000) |
| ampere | <physics, unit> The standard unit for measuring the strength of an electric current representing the flow of one coulomb of electricity per second. 1 kiloampere = 1000 amperes, 1 megampere = 1,000,000 amperes. Abbreviation: A (13 Nov 1997) |
