"[E]xperiments with a simple little machine, designed to mimic certain elementary features of animal behavior... Consisting only of two vacuum tubes, two motors, a photoelectric cell and a touch contact, all enclosed in a tortoise-shaped shell, the model was a species of artificial creature which could explore its surroundings and seek out favorable conditions. It was named Machine speculatrix."
William Grey Walter was an American-born British neurophysiologist, cybernetician and robotician.
"In any case there is an intense modern interest in machines that imitate life. The great difference between magic and the scientific imitation of life is that where the former is content to copy external appearance, the latter is concerned more with performance and behavior."
"The mechanism of learning is of course one of the most enthralling and baffling mysteries in the field of biology."
"[A]n electro-mechanical creature which behaves so much like an animal that it has been known to drive a not usually timid lady upstairs to lock herself in her bedroom, an interesting blend of magic and science."
"Rapidly going over what I could recall of Jim Bursleys information about pathological curves confirmed the conjecture. The snowball curve, derived from an equilateral triangle, is a perimeter of infinite length enclosing a finite area. The angles or points of the perimeter are uncountable. An equilateral triangle projected integrally in the third dimension is a triangular pyramid of equal surfaces. The three-dimensional snowflake derived from this pyramid--hence its diamantine appearance--is a finite volume enclosed in a surface of infinite area. The convolutions of such a surface, to be gathered around its defined content extrude a number of discrete angles or points beyond all possibility of computation. The pressure on each point is infinitesimal, unmeasurably small; the total external pressure exerted on any part of the surface is an aggregate of infinitesimal values, itself infinitesimal."
"In a modest villa on the outskirts of Bristol lives Dr Grey Walter, a neurologist, who makes robots as a hobby. They are small, and he doesn’t dress them up to look like men – he calls them tortoises. And so cunningly have their insides been designed that they respond to the stimuli of light and touch in a completely life-like manner. This model is named Elsie, and she sees out of a photo-electric cell which rotates about her body. When light strikes the cell, driving and steering mechanisms send her hurrying towards it. If she brushes against any objects in her path, contacts are operated which turn the steering away, and so automatically she takes avoiding action. Mrs Walter’s pet is Elmer, Elsie’s brother, in the darker vest. He works in exactly the same way. Dr Walter says that his electronic toys work exactly as though they have a simple two-cell nervous system, and that, with more cells, they would be able to do many more tricks. Already Elsie has one up on Elmer: when her batteries begin to fail, she automatically runs home to her kennel for charging up, and in consequence can lead a much gayer life."
"In the dark ages before the invention of the electronic vacuum tube there were many legends of living statues and magic pictures. One of the commonest devices of sorcerers and witches was the model of an enemy which somehow embodied his soul, so that injury to the model would be reflected by suffering or death of the original... Idolatry, witchcraft and other superstitions are so deeply rooted and widespread that it is possible that even the most detached scientific activity may be psychologically equivalent to them; such activity may help to satisfy the desire for power, to assuage the fear of the unknown or to compensate for the flatness of everyday existence."
