Postscript: Claude Elwood Shannon (April 30, 1916-February 24, 2001) was an American mathematician and founder of information theory. He received a bachelor's degree from the University of Michigan in 1936, a master's degree and a doctorate degree from the Massachusetts Institute of Technology in 1940, and entered Bell Labs in 1941. Shannon proposed the concept of information entropy, which laid the foundation for information theory and digital communication. The main papers include: Master's thesis "Symbolic Analysis of Relays and Switching Circuits" in 1938, "Mathematical Principles of Communication" in 1948 and "Communication under Noise" in 1949.

If you are not in the field of communication, Shannon may be a stranger, and his contribution does not feel so "conspicuous", but Shannon is actually very great. Information existed before Shannon, just as inertia was to Newton. But before Shannon, almost no one thought that information can be an idea, a measurable quantity. Before Shannon, information was a telegram, a photo, a paragraph, or even a song. After Shannon, information was completely abstracted into bits. This cartoon does not talk about information entropy, because I personally think that it is a bit troublesome to understand it by using a lot of analogies. It is deliberately bypassed, and interested students can read related materials.
