In 1956, he was elected as a member of the National Academy of Sciences In 1957, he was elected as an academician of the American Academy of Arts and Sciences Won the Shannon Award in 1973 In 1985, he was elected as an academician of the National Academy of Engineering In 1991, he was elected as a foreign academician of the Royal Society
From 1958 to 1978, he served as Donnor Professor of Science at MIT.
In 1973, at the International Symposium on Information Theory held in Ashkelon, Israel, IEEE namedShannon AwardAnd awarded this award to Shannon himself.[22]
In 1978, he retired from MIT and became an honorary professor of MIT.
In 1937, Claude Elwood Shannon, in his master's thesis A Symbolic Analysis of Relay and Switching Circuits, scientifically and rigorously discussed how to useBoolean algebraAnalyze and synthesize the relay circuit.In 1940, Shannon won the American Engineer Award of Alfred Noble Association for this achievement.[5]
During his doctoral studies, Shannon not only continued to study switch theory, but alsoDifferential analyzerResearch.This analyzer is an early mechanical analog computer used to obtainordinary differential equation Numerical solution of.In 1941, Shannon published his paper Mathematical Theory of the Differential Analyzer.With the development of analog computer theory, he also tried to understand how digital computers can accomplish similar computing tasks.[5]
In the summer of 1941, Shannon took part in an elite group specializing in fire control systems at Bell Laboratories to design a targeting device for observing enemy aircraft or missiles and calculating the targeting of anti-aircraft missiles. This device supported Britain's fight against German V1 rocketsV2 RocketAbility.In his spare time, Shannon is still committed to the research of switch theory and mathematical theory of communication.[5]

staythe Second World WarDuring this period, Shannon became very interested in cryptography, and he realized that the research on the fundamental problems of cryptography was closely related to the thought of communication theory he was studying at that time.Many of his achievements have important applications in voice encryption equipment, which isFranklin Delano RooseveltandChurchillThe main means of communication used during war.In 1945, Shannon submitted a confidential document entitled A Mathematical Theory of Cryptography to Bell Laboratories. This achievement was officially published in 1949 after the end of the Second World War under the title of Communication Theory of Secure Systems,This paper has established a set of mathematical theories for the research of symmetric cryptography. Since then, cryptography has become cryptography, from an art to a real science.[5]
Since 1940, Shannon has spent eight years to establish a set of mathematical theories for the communication system.His theory involves the whole process of communication processing, including communication source, data compression, channel coding, modulation, channel noise, demodulation, error detection, error correction, etc.The theory focuses on the performance of the best communication system and how to approach it.Finally in 1948, Shannon published A Mathematics Theory of Communication in the Bell System Technical Journal, marking the birth of information theory. In this paper, Shannon proposedentropy(entropy), gives the definition of quantifiable information, and deduces a series of theorems.In 1949, Shannon published the article "Communication under Noise" in the journal Bell System Technical Journal. In this paper, Shannon clarified the basic problems of communication, gave the model of communication system, proposed the mathematical expression of the amount of information, and solvedchannel capacity , source statistical characteristicsSource code、channel coding And a series of basic technical problems.[5]

In 1949, Shannon published Programming a Computer for Playing Chessartificial intelligenceA pioneer work.In 1950, Shannon invented the mechanical mouse "Theseus", which can learn to walk the maze by itself, becoming the prototype of the first artificial intelligence device.In 1951, he published the paper Presentation of a Maze Solving Machinemachine learningThe pioneer works of.In 1953, he designed a "Mind Reading" machine, which can observe, remember and analyze the samples of each other's past choices, and try to guess the next possible choice.[5]
In 1954, Shannon and Edward Moore cooperated to conduct a theoretical study on the calculation of unreliable components. They increased the redundancy of contacts to improve the reliability of relay circuits. This result is of great theoretical significance and is closely related to the problem of disturbed channel communication.In 1959, Shannon published the paper Coding Theorems for a Discrete Source with Fidelity Criterion, which createdRate distortion theoryA bridge is built between continuous messages and discrete messages, which provides a foundation and an effective tool for signal digitization.In 1960, Shannon published his paper Two way Communication Channel, which created the multi-user information theory.Shannon also put forward the idea of applying information theory to biological systems. In his opinion, machines and organisms have common characteristics.[5]
Shannon has also done research on the application of information theory to the optimal investment strategy. He believes that the stock market is a "disturbed signal" associated with time series.The problem is to properly select and adjust the portfolio of securities so thatutility function The maximum value is reached.He put forward some theories about the growth rate of investment, but did not publish them.[5]
Academic treatise
As of February 2001, Claude Elwood Shannon had published at least 127 papers and participated in the editing of several books, but had not published any works alone.[17]
academic exchange
In 1958, Claude Elwood ShannonPrinceton University Vanuxem academic lecture was held.
In 1985, attended theBrightonInternational Seminar on Information Theory.[20]
personnel training
During his tenure as a professor at MIT, Claude Elwood Shannon was rare as a student tutor. Most of the time, when he talked with students, he would find an interesting and novel new direction for students' research.From 1958 to 1978, he supervised three doctoral students.Shannon doesn't teach ordinary courses at MIT, but he often holds group meetings for students.[17][18]

In the 1980s, Claude Elwood Shannon's memory began to decline seriously, and later he suffered from Alzheimer's disease.[20]
Claude Elwood Shannon is recognized as the father of information theory in the world. He is full of foresight and insight, and has laid the foundation of modern communication technology, modern digital logic circuit and modern cryptography at one fell swoop;At the same time, he has a wide range of interests and has made many pioneering work in graph theory and network flow, artificial intelligence, human-computer interaction, computational biology and other fields.(School of Information Science and Technology, Shanghai University of Science and TechnologyComment)[6]
Claude Elwood Shannon is a mathematician, but he is different from most mathematicians. He likes engineering very much and likes to make many clever and intelligent machines by himself, so he is also an engineer with extraordinary creativity.(Professor and doctoral supervisor of School of Communication Engineering, Xi'an University of Electronic Science and TechnologyWang YuminComment)[9]
Claude Elwood Shannon's works are more like engineering, but Shannon's mathematical intuition is surprisingly accurate. He is not only a first-class mathematician, but also a first-class engineer.(A.N. Kolmogorov, academician of the former Soviet Academy of Sciences and mathematician, commented on the 1954 International Congress of Mathematicians)[9]
The New York Times called him a "playful genius who invented the bit,separated the medium from the message, and laid the foundations for all digital communications.)。(《New York Times》Comment)[13]
Claude Elwood Shannon was one of the greatest of the giants who created the information age.(commented by M. Mitchell Waldrop, senior editor of Science magazine)[13]
Dr. Claude Elwood Shannon is not only the father of information theory, but also has made fundamental contributions to data compression, digital computers, cryptography, circuit complexity, network flow, juggling, artificial intelligence and human-computer interaction.(Department of Computer Science and Engineering, Shanghai Jiaotong UniversityComment)[15]
