Unlike McCaffrey's black crystal transceivers, Le Guin's ansibles are not mated pairs: it is possible for an ansible's coordinates to be set to any known location of a receiving ansible.

" The official name is Philotic Parallax Instantaneous Communicator ," explains Colonel Graff in Ender's Game, " but somebody dredged the name ansible out of an old book somewhere.

The ansible is also featured in the video game Advent Rising, for which Card helped write the story.

There is a brief reference to the ansible in Winning Colors.

The ansible itself is a major plot element, nearly a MacGuffin in Moon's Vatta's War series.

There is no currently known way to build an ansible.

With no other way to save him, the colony declares itself in rebellion, Jane shuts off outside ansible contact, Miro is rescued, and Ender enters the forest to negotiate the aforementioned treaty.

; Limited communication: A central theme to Traveller is that there is no form of faster-than-light information transfer – meaning no ansible, subspace radio or hyper-wave communication technology is available.

It is also notable for its description of the invention of the new physics that is the basis for the fictional ansible, an instantaneous communications device that plays a critical role in Le Guin's Hainish Cycle.

The idea of an ansible is known but none yet exists-Shevek's new physics may be-in fact, eventually is-the key.

The sixth, The Word for World is Forest, has the League of Worlds and the ansible as new creations.

Most notable is the ansible, an instant-communication device that keeps worlds in touch with each other.

Shevek's work made the ansible possible-it is mentioned in his tale that engineers decided they could build it once the correct theory was found.

She is losing her memories and concentration as the vast computer network connected to the ansible is being shut down.

Jane is granted possession of Young Val's body, and thus is not destroyed when the ansible shuts down.

Eventually research ordered by the government on another planet, Path, leads a young genius girl, Han Qing-jao, to deduce the existence of Jane, who is inextricably tied to the ansible system.

However, the report to the authorities is dispatched regardless and the government enacts a plan to temporarily deactivate the ansible network to purge Jane from the system.

" The official name is Philotic Parallax Instantaneous Communicator ," explains Colonel Graff in Ender's Game, " but somebody dredged the name ansible out of an old book somewhere ".

Early in the series, philotic energy is used as a form of faster-than-light communication, in which messages are transmitted instantaneously via ansible.

An ansible is a hypothetical machine capable of instantaneous or superluminal communication used in all of Ender ’ s universe in all novels.

Le Guin's ansible was said to communicate " instantaneously ", but other authors have adopted the name for devices only capable of finite-speed communication, although still faster than light.

Jane's aiúa is capable of transcending this corporeal form and returning to the philotic link of the Mother-Trees, or the reconstructed ansible network of which she was born, thus preserving the instantaneous method of travel.

The Ekumen stories tell of the efforts to re-establish a civilization on a galactic scale through NAFAL ( Nearly As Fast As Light ) interstellar travel taking years to travel between stars, although only weeks or months from the viewpoint of the traveler, because of time dilation, and through instantaneous interstellar communication using the ansible.

Le Guin's concept has been borrowed explicitly by several other well-known authors, even to the extent of using the name of the communication device ( the " ansible ").

Humanity picked up several important pieces of technology from the Formic equipment, including gravity control and the possibility of faster-than-light communication, the ansible.

The word ansible was coined by Ursula K. Le Guin in her 1966 novel Rocannon's World.

Her award-winning 1974 novel The Dispossessed, a book in the Hainish Cycle, tells of the invention of the ansible.

Jonathan Rosenberg, author / artist of the humorous science fiction webcomic Scenes from a Multiverse, references an ansible powered by a quantum-entangled ferret in the 2012-Jun-25 edition of the comic.

In The Left Hand of Darkness, the ansible " doesn't involve radio waves, or any form of energy.

Orson Scott Card's Ender's Game series uses the ansible as a plot device.

Much of the story line revolves around various parties attacking or repairing ansibles, and around the internal politics of ISC ( InterStellar Communications ), which holds a monopoly on the ansible technology.

He leaves as soon as possible, with his only companion being Jane, an artificial sentience existing within the ansible computer network by which spaceships and planets communicate instantly across galactic distances.

The invention of the ansible places the novel first in the internal chronology of the Hainish Cycle, although it was the fifth Hainish novel published.

City of Illusions mentions automatic death-machines that work on the ansible principle and can strike instantly at distant worlds.

The child of this problem was Mr. Brown's famous Serial No. 1 Universal Milling Machine, the archtype from which is descended today's universal knee-type milling machine used throughout the world.

The original machine, bearing its famous serial number, is still on exhibition at the Brown & Sharpe Precision Center in Providence.

Recently added is the Brown & Sharpe turret drilling machine which introduces the company to an entirely new field of tool development.

This machine, operating at speeds up to 350,000 revolutions per minute, is believed to provide one of the fastest mechanical operations in industry today.

A relatively simple switching arrangement reverses the cycle so that the machine literally runs backward, and the heat is extracted from outdoor air and turned indoors.

Now, the machine has been improved to a point where it is generally more economical than oil heat at temperatures down to 15 degrees.

The body is a heat machine, and 20 to 25 guests can easily double your cooling load.

A BTU is a unit of heat, and the BTU rating of a conditioner refers to how much heat your machine can pump out of your house in an hour.

Hard-surface cleaning in household application is represented by two classes of alkaline products: ( 1 ) the formulations made expressly for machine dishwashers, and ( 2 ) the general-purpose cleaners used for walls and woodwork.

The major training need of a new industrial plant is a short period of pre-employment training for a large number of semi-skilled machine operators.

The one- or two-digit number of the index word or electronic switch was used in the operand of a symbolic machine instruction to specify indexing or as a parameter which is always an index word or electronic switch, e.g., 3.

The resident staff is large and consists of professional assistants, graduate students, abstractors, librarian, technical editor, machine operators, secretarial help, and others.

The suds box drain is arranged at the start to deliver into the raised main drain pipe ( thus returning suds to soap box ) and the machine is started.

The machine is equipped with a pipe for injecting live steam that is capable of raising the temperature of water at an eight-inch level from 110-degrees to 140-degrees-F ( 38*0 to 60*0C. ) in less than two minutes.

It is not through space nor time that the time machine most approved by science fiction must travel for a visit to the permanent prehistoric past, or the ever-existent past-fantasy future.

If an expensive and specialized piece of machinery is needed -- such as a spray rig, a combine, or a binder -- it is better to pay someone with a machine to do the work.

Of the two, Porter is justly the better known, for he went far beyond the vital finding of fiction for films to take the first step toward fashioning a language of film, toward making the motion picture the intricate, efficient time machine that it has remained since, even in the most inept hands.

But humans can do something equally useful, in the case of certain enumerably infinite sets: They can give explicit instructions for determining the nth member of the set, for arbitrary finite n. Such instructions are to be given quite explicitly, in a form in which they could be followed by a computing machine, or by a human who is capable of carrying out only very elementary operations on symbols.

Gurevich: "... Turing's informal argument in favor of his thesis justifies a stronger thesis: every algorithm can be simulated by a Turing machine ... according to Savage, an algorithm is a computational process defined by a Turing machine ".

There is a wide variety of representations possible and one can express a given Turing machine program as a sequence of machine tables ( see more at finite state machine, state transition table and control table ), as flowcharts ( see more at state diagram ), or as a form of rudimentary machine code or assembly code called " sets of quadruples " ( see more at Turing machine ).
