We can perhaps understand the apparently quicker rate of change in terrestrial and in more highly organised productions compared with marine and lower productions, by the more complex relations of the higher beings to their organic and inorganic conditions of life, as explained in a former chapter.
However, the value of a field and its rate of change with time are like the position and velocity of a particle: the uncertainty principle implies that the more accurately one knows one of these quantities, the less accurately one can know the other.
So in empty space the field cannot be fixed at exactly zero, because then it would have both a precise value (zero) and a precise rate of change (also zero).
We have some evidence that suggests they understand the whole process, and they certainly seem able to predict the rate of change in the spiral arm.
The display was updated once a second, and he had to instantly judge the rate of change in the rising topography, and any heading correction necessary, then control the plane accordingly.
The aircraft responded to stick displacement, but that displacement merely created a rate of change, not the change itself.
The rate of change of pronunciation is probably dependent, to some extent, on the state of a civilization, and changes should take place more rapidly in periods when illiteracy is high, and schools and spelling have less braking effect.
It was not a progressive process, a steady rate of change, minute by minute, hour by hour, and so forth.
