Claude Shannon: Master's thesis revolutionizes digital circuit design

Claude Shannon, born in 1916, made groundbreaking contributions in computer science. His master's thesis in 1937 introduced the concept of applying Boolean algebra to electrical circuits, revolutionizing digital circuit design and laying the foundations of computer architecture. He showed how switches in series function as an 'AND' gate, while parallel switches function as an 'OR' gate. His work became the basis for designing circuits using mathematical principles rather than manual methods. Shannon's invention of the information theory in 1948 formalized the concept of bits as units of information and introduced the measure of entropy as a measure of information. He also developed the idea of maximum bit rate in communication channels. His work on cryptography during World War II and collaborations with Alan Turing contributed to advancements in code-breaking techniques and secure communication. Shannon's contributions to AI include a generative language model algorithm that could create coherent sentences by outputting the next word following a given word. Shannon's work exemplifies his multidisciplinary abilities and creativity in various domains besides computer science.
