. Design for a brain; the origin of adaptive behavior. Calculators; Central nervous system -- Mathematical models; Behavior; Brain -- physiology. 4/5 STABILITY. o O O D o o o Figure 4/5/1 : Field of the two-variable system described in the text. Below is shown the cube as it would appear in elevation when its main face, shown by a heavier line, is tilted through the angle x. consideration, and this departure correspond^to the instability. The uncertainty of the movements near O corresponds to the uncertainty in the behaviour of the card when released from the vertical position. The Watt's governor has a more complicated field, but an approximation may be obtained without difficulty. The system may be specified to an approximation sufficient for our purpose by three variables: (x) the speed of the engine and governor (), (y) the distance between the weights, or the position of the throttle, and (z) the velocity of flow of the steam. (y represents either of two quantities because they are rigidly connected). If, now, a disturbance suddenly accelerates the engine, increasing x, the increase in x will increase y; this increase in y will be followed by a decrease of z, and then by a decrease of x. As the changes occur not in jumps but continuously, the line 47.
