A Quote by Norbert Wiener
Just as entropy is a measure of disorganization, the information carried by a set of messages is a measure of organization. In fact, it is possible to interpret the information carried by a message as essentially the negative of its entropy, and the negative logarithm of its probability. That is, the more probable the message, the less information it gives. Cliches, for example, are less illuminating than great poems.

Claude Shannon, the founder of information theory, invented a way to measure 'the amount of information' in a message without defining the word 'information' itself, nor even addressing the question of the meaning of the message.
You know, entropy is associated thermodynamically, in systems involving heat, with disorder. And in an analogous way, information is associated with disorder, which seems paradoxical. But when you think about it, a bit of information is a surprise. If you already knew what the message contained, there would be no new information in it.
We have more information now than we can use, and less knowledge and understanding than we need. Indeed, we seem to collect information because we have the ability to do so, but we are so busy collecting it that we haven't devised a means of using it. The true measure of any society is not what it knows but what it does with what it knows.
It was not easy for a person brought up in the ways of classical thermodynamics to come around to the idea that gain of entropy eventually is nothing more nor less than loss of information.
I don't think we should have less information in the world. The information age has yielded great advances in medicine, agriculture, transportation and many other fields. But the problem is twofold. One, we are assaulted with more information than any one of us can handle. Two, beyond the overload, too much information often leads to bad decisions.
That which today calls itself science gives us more and more information, and indigestible glut of information, and less and less understanding.
We hypostatize information into objects. Rearrangement of objects is change in the content of the information; the message has changed. This is a language which we have lost the ability to read. We ourselves are a part of this language; changes in us are changes in the content of the information. We ourselves are information-rich; information enters us, is processed and is then projected outward once more, now in an altered form. We are not aware that we are doing this, that in fact this is all we are doing.
What do we measure when we measure time? The gloomy answer from Hawking, one of our most implacably cheerful scientists, is that we measure entropy. We measure changes and those changes are all for the worse. We measure increasing disorder. Life is hard, says science, and constancy is the greatest of miracles.
Negative information is that which, immediately upon acquiring, causes the recipient to know less than he did before.
In an information economy, entrepreneurs master the science of information in order to overcome the laws of the purely physical sciences. They can succeed because of the surprising power of the laws of information, which are conducive to human creativity. The central concept of information theory is a measure of freedom of choice. The principle of matter, on the other hand, is not liberty but limitation- it has weight and occupies space.
Information wants to be free.' So goes the saying. Stewart Brand, the founder of the Whole Earth Catalog, seems to have said it first.I say that information doesn't deserve to be free.Cybernetic totalists love to think of the stuff as if it were alive and had its own ideas and ambitions. But what if information is inanimate? What if it's even less than inanimate, a mere artifact of human thought? What if only humans are real, and information is not?...Information is alienated experience.
There are all sorts of despicable people who journalists have done interviews with, and it's been useful. Isn't more information better than less information?
Information: the negative reciprocal value of probability.
The body itself is an information processor. Memory resides not just in brains but in every cell. No wonder genetics bloomed along with information theory. DNA is the quintessential information molecule, the most advanced message processor at the cellular level - an alphabet and a code, 6 billion bits to form a human being.
The message for the smart investor is to watch out. Do not get carried away with news reports and turn smart by pooling information with like-minded investors.
We receive experience from nature in a series of messages. From these messages we extract a content of information: that is, we decode the messages in some way. And from this code of information we then make a basic vocabulary of concepts and a basic grammar of laws, which jointly describe the inner organization that nature translates into the happenings and the appearances we meet.
