Quotes by Claude Shannon

The universe speaks in the language of mathematics and information.

Interview

Every interaction is an exchange of information.

Lecture

The quest for understanding is what drives us forward.

Interview

The beauty of a theory lies in its simplicity and explanatory power.

Lecture

Our existence is a continuous stream of information processing.

Interview

The more we understand information, the more we understand ourselves.

Lecture

The capacity of a noisy channel is the maximum rate at which information can be transmitted over the channel with arbitrarily small error probability.

A Mathematical Theory of Communication 1948

It is possible to send information at a rate approaching the channel capacity with arbitrarily small error probability.

A Mathematical Theory of Communication 1948

The significant aspect is not the meaning of the individual symbols but the statistical properties of the ensemble of messages.

A Mathematical Theory of Communication 1948

The problem of communication is not to transmit meaning, but to transmit symbols.

A Mathematical Theory of Communication 1948

The amount of information is measured by the reduction of uncertainty.

A Mathematical Theory of Communication 1948

A device for playing chess, if it is to play well, must be able to 'think' several moves ahead.

Programming a Computer for Playing Chess 1950

The machine will be able to play a fairly respectable game of chess, certainly better than the average player.

Programming a Computer for Playing Chess 1950

The machine can be said to 'learn' if its performance improves with experience.

Programming a Computer for Playing Chess 1950

The problem of designing a machine to play chess is not one of finding a perfect algorithm, but of finding a good heuristic.

Programming a Computer for Playing Chess 1950

The most important thing is to have a good problem.

Various interviews/anecdotes

I'm not interested in whether a machine can think, but whether a machine can do something useful.

Various interviews/anecdotes

Information is not meaning.

A Mathematical Theory of Communication 1948

The mathematical theory of communication is essentially a branch of applied probability theory.

A Mathematical Theory of Communication 1948

The problem of cryptography is essentially the problem of making a message unintelligible to anyone but the intended receiver.
