Shannon's information theory or brainwave, which has contributed greatly to human progress?

Shannon, who graduated from college, noticed the advertisement posted on the bulletin board for an assistant researcher of operational differential analyzer at MIT. Shannon applied for this position and studied for a master's degree at work. Why did Shannon apply for this position? This stems from his lifelong interest in Boolean logic. At that time, the differential analyzer was actually an early analog computer, and it could solve high-order differential equations by controlling the operation through a node circuit composed of hundreds of relays. Shannon studied symbolic logic and Boolean algebra at the University of Michigan, which became the mathematical theoretical basis for his later study of binary. China people have long noticed the universality of dualism and developed the philosophy system of Yin and Yang. Unfortunately, people in China have never described the binary phenomenon formally from the mathematical point of view, and their understanding of this object is metaphysically vague, not scientifically accurate. This is worthy of our contemporary thinking.

Shannon is four years younger than Turing. These two giants of science are wizards in the history of human civilization. In fact, Shannon's work in the master's thesis has laid the hardware foundation of the computer. Turing also published the concept of programmable general-purpose computer. Their research is like the proverbs of the prophet, guiding future generations how to carry out the computer revolution. During World War II, both of them were responsible for the encryption and decryption of communication at the same time, so they had the opportunity to meet and communicate. Due to special political reasons, although both of them are cryptographers, what they discuss most is artificial intelligence instead of cryptography.

Shannon also studied the application of information theory in the optimal investment strategy. He believes that the stock market is a "disturbance signal" related to time series. The problem is to maximize the utility function by properly selecting and adjusting the portfolio. He put forward some theories about investment growth rate, but they were not published. However, he once held a seminar on investment theory at MIT, which attracted hundreds of listeners. Shannon is not an armchair strategist. He actually invested in the ordinary market and made a lot of money. His friends followed his advice and made a lot of money.
