A variable in an experiment which is held constant in order to assess the relationship between multiple variables [a], is a control variable. [2] [3] A control variable is an element that is not changed throughout an experiment because its unchanging state allows better understanding of the relationship between the other variables being tested.
Artificial intelligence is a recurrent theme in science fiction, whether utopian, emphasising the potential benefits, or dystopian, emphasising the dangers.. The notion of machines with human-like intelligence dates back at least to Samuel Butler's 1872 novel Erewhon.
The variables made to remain constant during an experiment are referred to as control variables. For example, if an outdoor experiment were to be conducted to compare how different wing designs of a paper airplane (the independent variable) affect how far it can fly (the dependent variable), one would want to ensure that the experiment is ...
From the science fiction series Perry Rhodan (1961) Merlin from the H. Beam Piper novel The Cosmic Computer (originally Junkyard Planet ) (1963) Simulacron-3 , the third generation of a virtual reality system originally depicted in the science fiction novel Simulacron-3 (a.k.a. "Counterfeit World") by Daniel F. Galouye (1964) and later in film ...
A variable may be thought to alter the dependent or independent variables, but may not actually be the focus of the experiment. So that the variable will be kept constant or monitored to try to minimize its effect on the experiment. Such variables may be designated as either a "controlled variable", "control variable", or "fixed variable".
Lots of gun-policy wonkery to follow—but first, a confession and a wager. Confession: I am that guy who has to fight the urge to edit the entire Internet.
Colossus (1966) is a series of science fiction novels and film about a defense super-computer called Colossus that was "built better than we thought" when it begins to exceed its original design. [24] As time passes Colossus assumes control of the world as a logical result of fulfilling its creator's goal of preventing war.
The same is true for intervening variables (a variable in between the supposed cause (X) and the effect (Y)), and anteceding variables (a variable prior to the supposed cause (X) that is the true cause). When a third variable is involved and has not been controlled for, the relation is said to be a zero order relationship. In most practical ...
