| 説明 | I put up an earlier version of this and had asked for comments and critiques. Unfortunately I had comments inactivated. I wrote that I was inspired by a book titled The Information: A History, a Theory, a Flood by James Gleick. I purposely have made this dense with many references to information in its different forms with representations of some current applications and incarnations. Double click and view large.Claude Elwood Shannon (April 30, 1916 – February 24, 2001) was an American mathematician, electrical engineer, and cryptographer known as a "father of information theory" As a 21-year-old master's degree student at the Massachusetts Institute of Technology (MIT), he wrote his thesis demonstrating that electrical applications of Boolean algebra could construct any logical numerical relationship. Shannon contributed to the field of cryptanalysis for national defense of the United States during World War II, including his fundamental work on codebreaking and secure telecommunications. In 1948 he published "A Mathematical Theory of Communication", an article in two parts in the July and October issues of the Bell System Technical Journal. This work focuses on the problem of how best to encode the message a sender wants to transmit. Shannon developed information entropy as a measure of the information content in a message, which is a measure of uncertainty reduced by the message. In so doing, he essentially invented the field of information theory.[adapted from Wikipedia] |
