Extractions: @import url(../_i/bob.css); The fussy old toad pictured here was the original I, Cringely mascot, circa 1997. By Robert X. Cringely I knew Claude Shannon, not well, but I knew him. We met a few times because I have made a point of trying to meet my heroes whenever possible. Our only substantive conversation that I can recall was about juggling, a hobby he did well and I can't do at all. But if Shannon wanted to talk about juggling, heck, we'd talk about juggling. (It's no accident that many computer folk like juggling. It's in their genes.) There was no reason, back in 1938, for Claude Shannon to start thinking about information, to invent the concept of a data channel, to choose binary encoding. He just made it all up in his mind and changed the world by doing so. There was little that could be done with these ideas back then, yet he thought them up anyway. We owe the guy a lot. Today, things are different. The auto industry analogy that I couldn't apply to Shannon in 1938 actually applies quite well to the world of computing today. That's because what was an area of interest has become an industry. And not just any industry, it's an industry so big and so important that it simultaneously drives our economy and enables it to function. Computing is serious business, serious money - too serious to afford the very behavior that made its existence possible. What companies still engage in basic research and really mean it? Hardly any. This may be reality, but it is not a good reality.

Claude Shannon's Master's Thesis 1938 AD claude shannon s master s Thesis. In fact it was not until 1938 that claude E. shannon published an article based on his master s thesis at MIT. http://www.maxmon.com/1938ad.htm
Extractions: Claude Shannon's master's Thesis Around the 1850s, the British mathematician George Boole was busily inventing a new form of mathematics, in which he represented logical expressions in a mathematical form now known as Boolean Algebra a Unfortunately, with the exception of students of philosophy and symbolic logic, Boolean Algebra was destined to remain largely unknown and unused for the better part of a century. In fact it was not until 1938 that Claude E. Shannon published an article based on his master's thesis at MIT. (Shannon's thesis has since been described as: "Possibly the most important master's thesis of the twentieth century." In his paper, which was widely circulated, Shannon showed how Boole's concepts of TRUE and FALSE could be used to represent the functions of switches in electronic circuits. It is difficult to convey just how important this concept was; suffice it to say that Shannon had provided electronics engineers with the mathematical tool they needed to design digital electronic circuits, and these techniques remain the cornerstone of digital electronic design to this day. a Apropos of nothing at all, Shannon is also credited with the invention of the rocket-powered Frisbee, and is famous for riding down the corridors at Bell Laboratories on a unicycle while simultaneously juggling four balls.

Extractions: Video: Claude Shannon: Father of the Information Age . Co-produced by Cal-(IT)² and UCSD-TV, based on the Shannon Symposium sponsored by Cal-(IT)² and UCSD's Jacobs School of Engineering, February 2002. It is difficult to overstate the importance of Claude Shannon's contributions to the field of communications. In a landmark 1948 paper, Shannon laid out the basic principles underlying digital communications and storage, revolutionizing the way that engineers approached the subject. He paved the way for the powerful codes now used in telephony, wireless communications, satellite communications, deep space communications, and storage devices such as CD players and hard drives; and he laid the groundwork for compression algorithms used for audio and video signals. Many concepts that seem obvious today were first introduced in his paper, "A Mathematical Theory of Communication," published in two parts in the Bell System Technical Journal. The use of the term "bit" as a unit of information first appeared in this paper. In an age in which communication took place with continuous, analog waveforms, it was a startling notion that information traveling across any communications system could be defined mathematically as some quantity of binary symbols. It was entirely new that information of any kind whether for use on a telegraph, telephone, radio, or television could be decomposed into zeros and ones, encoded, transmitted, and decoded at the other end.

Extractions: Er schrieb eine Reihe von Arbeiten, auf denen heute die Computer- und IT-Industrie beruhen. Vor allem das 1948 publizierte Buch "The Mathematical Theory of Communication", welche er mit Warren Weaver gemeinsam geschrieben hat, zeigt, dass auch in gestörten Kanälen eine korrekte Übertragung von Information möglich ist. Das war der Grundstein für die statistische Kommunikationstheorie. Im selben Jahr wurde auch das Buch "Programming A Computer Playing Chess" veröffentlicht, es war die Basis für den bau von Computerspielen in den folgenden Jahren. 1950 baute Shannon erstmals eine Modell für die automatische Orientierung, genannt das Maus im Labyrinth (wird unten näher beschrieben). Shannon wurde auch als Pioniere auf dem Gebiet der künstlichen Intelligenz bezeichnet, da er in den 50ziger Jahren eine Arbeit über Computer und Automaten schrieb.

Extractions: Claude E. Shannon can't sit still. We're at his home, a stuccoed Victorian edifice overlooking a lake north of Boston, and I'm trying to get him to recall how he came up with the theory of information. But Shannon, who is a boyish 73, with an elfish grin and a shock of snowy hair, is tired of expounding on his past. Wouldn't I rather see his toys? Without waiting for an answer, and over the mild protests of his wife Betty, he leaps from his chair and disappears into the other room. When I catch up with him, he proudly shows me his seven chess-playing machines, gasoline-powered pogostick, hundred-bladed jackknife, two-seated unicycle and countless other marvels. Some of his personal creations-such as a juggling W.C. Field mannequin and a computer called THROBAC that calculates in Roman numerals-are a bit dusty and in disrepair, but Shannon seems as delighted with everything as a 10- year old on Christmas morning. From childhood on, Shannon was fascinated by both the particulars of hardware and the generalities of mathematics. Growing up in Gaylord, Mich., he tinkered with erector sets and radios given to him by his father, a probate judge, solved mathematical puzzles supplied by his older sister, Catherine, who became a professor of mathematics. As an undergraduate at the University of Michigan he majored in electrical engineering and mathematics.
Extractions: Few books have had as lasting an impact or played as important a role in our modern world as The Mathematical Theory of Communication. Claude Shannon's major precept, that all communication is essentially digital, is now so commonplace among the modern digitalia that many wonder why Shannon needed to state such an obvious axiom.

Shannon: Eine Maschine, die Labyrinthe löst siehe auch Crashkurs Kommunikation Information hat keine Bedeutung. Als C.Shannon 1948 seine Informationstheorie veröffentlichte, hat sein Co-Autor W.Weaver diese Problematik vollständig ausgedrückt. Er schrieb, dass nicht nur sein Telefonapparat ein Transmitter von Signalen sei, sondern auch sein Sprechapparat: "Im mündlichen Gespräch ist das Gehirn die Informationsquelle, der Stimm-Mechanismus, der die Schallwellen, die durch die Luft (Kanal) übermittelt werden, produziert, ist der Transmitter. (...) Wenn ich mit Ihnen spreche, ist mein Hirn die Informationsquelle, mein vokales System der Transmitter" (Shannon/Weaver:98f). W.Weaver schreibt: Das Wort ,Information wird, in unserer Theorie, in einem spezifischen Sinn verwendet, der nicht mit der üblichen Verwendung des Wortes verwechselt werden darf. (...) Zwei Nachrichten, von welchen die eine wirklich bedeutungsvoll und die andere purer nonsense ist, können, was ihren Informationsgehalt betrifft, unter dem verwendeten Gesichtspunkt, exakt äquivalent sein. Es ist zweifellos diese Tatsache, die Shannon meint, wenn er sagt, dass ,der semantische Aspekt der Kommunikation für den technischen Aspekt irrelevant ist (Shannon:99).
