Webster's Dictionary (1913)
Origin: Cf. F. virtuel. See Virtue.
1. Having the power of acting or of invisible efficacy without the agency of the material or sensible part; potential; energizing.
Heat and cold have a virtual transition, without communication of substance.— Francis, Baron Verulam Bacon
Every kind that lives, Fomented by his virtual power, and warmed.— John Milton
2. Being in essence or effect, not in fact; as, the virtual presence of a man in his agent or substitute.
A thing has a virtual existence when it has all the conditions necessary to its actual existence.— Fleming, William
To mask by slight differences in the manners a virtual identity in the substance.— Thomas DeQuincey
Principle of virtual velocities Mechanics, the law that when several forces are in equilibrium, the algebraic sum of their virtual moments is equal to zero. — Virtual focus Opt., the point from which rays, having been rendered divergent by reflection of refraction, appear to issue; the point at which converging rays would meet if not reflected or refracted before they reach it. — Virtual image. Optics See under Image. — Virtual moment (of a force) Mechanics, the product of the intensity of the force multiplied by the virtual velocity of its point of application; — sometimes called virtual work. — Virtual velocity Mechanics, a minute hypothetical displacement, assumed in analysis to facilitate the investigation of statical problems. With respect to any given force of a number of forces holding a material system in equilibrium, it is the projection, upon the direction of the force, of a line joining its point of application with a new position of that point indefinitely near to the first, to which the point is conceived to have been moved, without disturbing the equilibrium of the system, or the connections of its parts with each other. Strictly speaking, it is not a velocity but a length. — Virtual work. Mechanics See Virtual moment, above.

<jargon, architecture> (Via the technical term virtual memory, probably from the term "virtual image" in optics)
1.Common alternative to logical; often used to refer to the artificial objects (like addressable virtual memory larger than physical memory) created by a computer system to help the system control access to shared resources.
2.Simulated; performing the functions of something that isn't really there. An imaginative child's doll may be a virtual playmate.
Opposite of real or physical. [Jargon File]

[via the technical term virtual memory, prob.: from the term virtual image in optics]
1.Common alternative to logical; often used to refer to the artificial objects (like addressable virtual memory larger than physical memory) simulated by a computer system as a convenient way to manage access to shared resources.
2.Simulated; performing the functions of something that isn't really there. An imaginative child's doll may be a virtual playmate. Oppose real .
