The best material model of a cat is another, or preferably the same, cat.
Interpretation
The most accurate way to understand a cat is through direct observation of another cat.
This quote by Norbert Wiener emphasizes the idea that the best way to understand the nature and behavior of a creature, such as a cat, is through the direct observation of similar entities. It suggests that models and representations can only be as good as the subjects they attempt to emulate, highlighting the importance of practical experience in understanding complex systems.
In practice
In a discussion about animal behavior, this quote could be used to highlight the importance of studying animals in their natural context.
In a very real sense, we are shipwrecked passengers on a doomed planet. Yet, even in a shipwreck, human decencies and human values do not necessarily vanish, and we must make the most of them. We shall go down, but let it be in a manner to which we may look forward as worthy of our dignity.
The Advantage is that mathematics is a field in which one's blunders tend to show very clearly and can be corrected or erased with a stroke of the pencil. It is a field which has often been compared with chess, but differs from the latter in that it is only one's best moments that count and not one's worst. A single inattention may lose a chess game, whereas a single successful approach to a problem, among many which have been relegated to the wastebasket, will make a mathematician's reputation.
I have said that the modern man, and especially the modern American, however much 'know-how' he may have, has very little 'know-what'
Any labor which competes with slave labor must accept the economic conditions of slave labor.
We have modified our environment so radically that we must now modify ourselves to exist in this new environment.
We are but whirlpools in a river of ever-flowing water. We are not stuff that abides, but patterns that perpetuate themselves. _x000D_ A pattern is a message, and may be transmitted as a message.
I'll change the posture of our federal government from being one of the most anti-science administrations in American history to one that embraces science and technology.
Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.
There cannot be a language more universal and more simple, more free from errors and obscurities...more worthy to express the invariable relations of all natural things [than mathematics]. [It interprets] all phenomena by the same language, as if to attest the unity and simplicity of the plan of the universe, and to make still more evident that unchangeable order which presides over all natural causes
We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75.
Whenever we find, in two forms of life that are unrelated to each other, a similarity of form or of behaviour patterns which relates to more than a few minor details, we assume it to be caused by parallel adaptation to the same life-preserving function.
The nuclear industry has this amazing record, even equipment from generations one and two. But nuclear mishaps tend to come in these big events - Chernobyl, Three Mile Island, and now Fukushima - so it's more visible.
