#428 How Claude Shannon Worked

Об эпизоде

Claude Shannon changed your life and you probably don't even know it. Claude is the father of information theory. He transformed information into bits and created the intellectual foundation for computers, the Internet, digital media, high-speed communication, and Artificial Intelligence. The way Claude Shannon worked is what interested me the most. He combined extraordinary abstract reasoning with an engineer’s instinct to build. He reduced complex problems to their essential structure. He connected ideas across mathematics, engineering, cryptography, artificial intelligence, investing, chess, juggling, and robotics. He treated every experience as material that he might later combine into a new insight. He was also relentlessly independent, guided more by curiosity and freedom than recognition, money, or usefulness. This episode is what I learned from rereading A Mind at Play: How Claude Shannon Invented the Information Age by Jimmy Soni and Rob Goodman.

A genius is simply someone who is usefully irritated." 1:36 — "It seems to be much easier to make two small jumps than one big jump in any kind of mental thinking." — Shannon 4:41 — "He was a man almost entirely written out of a history that's defined by self-promoters. His was a life spent in the pursuit of curious, serious play." 5:20 — "He worked with levity and played with gravity. He never acknowledged a distinction between the two." 6:00 — "Geniuses are the luckiest of mortals because what they do is the same as what they most want to do." 6:59 — "I do what comes naturally, and usefulness is not my main goal. I keep asking myself, 'How would you do this? Is it possible to make a machine to do this? Can I prove this theorem?'" — Shannon 11:50 — "Chemistry always seemed dull to me. There's too many isolated facts and too few general principles for my taste." — Shannon 19:09 — "Specialization is the death of genius." — Vannevar Bush 19:18 — "The possibilities of being at once both broad and deep did not pass with Leonardo da Vinci or Benjamin Franklin." — Vannevar Bush 25:13 — "I had the freedom to do anything I wanted from almost the day I started. They never told me what to work on." — Shannon on Bell Labs 26:41 — "I've been working on three different ideas simultaneously, and strangely enough, it seems a more productive method than sticking to one problem." — Shannon 32:55 — "My fondest dream is to someday build a machine that thinks, learns, communicates, and manipulates its environment in a fairly sophisticated way." — Shannon 35:05 — "Before Shannon, information was a telegram, a photograph, a paragraph, a song. After Shannon, information was entirely abstracted into bits." 38:04 — "After the effort of discovery, the effort of communication was secondary by far. He had solved a problem to his own satisfaction, and that, as far as he was concerned, was enough." 40:55 — "I've spent lots of time on totally useless things... He made no distinction between his interest in information and his interest in unicycles. They were all moves in the same game." 46:54 — "Shannon seemed to think with ideas more than with words or formulas. A new problem was like a sculptor's block of stone, and Shannon's ideas chiseled away the obstacles until an approximate solution emerged." — Ed Thorp 47:19 — "I simply removed everything that was not David." — Michelangelo 47:25 — "I don't think I was ever motivated by the notions of winning prizes. I was more motivated by curiosity, never by the desire for financial gain. I just wondered how things were put together." — Shannon 47:49 — "I think the history of science has shown that valuable consequences often proliferate from simple curiosity." — Shannon 48:37 — "The important people and events of history are the thinkers and innovators, the Darwins, the Newtons, the Beethovens, whose work continues to grow influence in a positive fashion." — Shannon
