Recent Contributions to the Mathematical Theory of Communication by The visually Impaired

The article was first published by Claude Shannon and was republished by Warren Weaver with an additional theory of communication. The paper discusses the three levels of communication problems which are Level A the technical problem, level B the semantic problem and level C the effectiveness problem. The communication problem is represented as the Information source that gives the message to the transmitter that gives the signal and makes noise source that gives to the receiver and takes the message to the destination. The problem A) is superficial because the information source from the transmitter is translated into signals and it focuses on the undesirable noise effect. The other problems are more philosophic. The semantic problems are to identify the meaning of the receiver and the effectiveness is to consider the aesthetic through the psychological and emotional aspects of the message. The transmitter of the message changes it in code such as symbols, words, numbers.  The channel of communication has the ability to transmit content outside the source of a given information such as the noise. If the noise is presented in the message the receiver would have many errors and complication to decrypt the message.

The interesting thing in the text is that there is an introduction to a mathematical theory which is a basic theory of cryptography and it is applied in all form of communication. This theory translates languages to another to complete the meaning of the message. This article is introducing theories of the logical problems and the design of a computer. Also it is interesting that the text is questioning if a computer thinks or if he is made to think with logic.
