Shannon claude (109 Ergebnisse)

paperback. Zustand: Good. Our good condition books are generally good for reading but not for gifting or collecting. They could have imperfections such as creasing, fanning, inscriptions, margin notes, yellowing, staining on edge or cover or pages, bumps, scuffs, etc etc (sometimes multiple of these). It's a wide category that encompasses anything that isn't almost-new down to anything that is slightly better than poor. We would NOT recommend gifting Good books - these should be considered reading copies. Our books are dispatched from a Yorkshire former cotton mill. We list via barcode/ISBN so please note that the images are stock images and may not be the exact copy you receive, furthermore the details about edition and year might not be accurate as many publishers reuse the same ISBN for multiple editions and as we simply scan a barcode or enter an ISBN we do not check the validity of the edition data when listing. If you're looking for an exact edition please don't order (at least not without checking with us first, although we don't always have time to check). We aim to dispatch prompty, the service used will depend on order value and book size. We can ship to most countries, see our shipping policies. Payment is via Abe only.…

Wraps. Zustand: Fine. 90-93 pages. 10 x 7 1/8 inches. A single sheet folded but lacking the original blue printed wrappers. Wraps. The American Mathematical Monthly first published this article in Vol 57, (Feb. 1950), pp 90-93. We offer here the original offprint issue but without the original blue printed wrappers. While we don't understand the mathematics here, one comment is fun: "If we were using this notation, department stores would find it much more difficult to camouflage the price of goods with $.98 labels." The typescript carbon in Shannon's files finishes there. But the final paper [ as offered here ] includes additional material, including a final paragraph explaining one reason for this notation: "Symmetrical notation offers attractive possibilities for general-purpose computing machines of the electronic or relay types. In these machines, it is possible to perform the calculations in any desired scale and only translate to the scale ten at input and output. The use of asymmetrical notation simplifies many of the circuits required to take care of signs in addition and subtraction, and to properly round off numbers." (p.93) "At the close of the decade, the [American Mathematical] Monthly published a beautiful, long paper by Andre Weil called the Future of Mathematics. It also published a short note in computer science by Claude Shannon called "A Symmetrical Notation for Numbers." Both papers foretold the future of mathematics." (Ewing, p. 134) PROVENANCE: The personal files of Claude E. Shannon (unmarked). There were multiple examples of this item in Shannon's files.

Wraps. Zustand: Near Fine. Later printing. Later printing. 2 pages. 10 7/8 x 8 3/8 inches (275 x 213 mm) Publisher's printed grey, blue and black wrappers, stapled. Five holes punched at the spine as issued. The upper corner tip bumped. Wraps. The earliest known form of this paper is an internal Bell Labs reproduced typescript. The Journal of Applied Physics, Vol 27, No. 1, pp. 42-43, January 1956 first published this paper, for which an offprint is known. Here offered in the Bell Telephone Systems Monograph Series (#2547: March 1956), a later printing. Abstract: "It is proved that any network of linearly wound potentiometers and fixed resistors have a curve of resistance versus shaft angle which is concave downward." and later "As part of a computer, a rheostat having a resistance that was a concave upward function of the shaft angle was needed. After many attempts to approximate it with networks of linearly wound potentiometers and fixed resistors, it became apparent that either it was impossible or that we were singularly inept network designers. Rather than accept the latter alternative, we have proved the following theorem." In short, Shannon and Hagelbarger proved it was impossible to build a needed electrical circuit with ANY network of linearly wound potentiometers and fixed resistors. This mathematical result is an excellent example of where a practical engineering solution was needed and could have been experimented upon endlessly had the mathematicians not stepped in and proved it impossible - a hallmark of much of Shannon's work. Paul J. Nahin surmises that this paper, whose results are sometimes called the Shannon-Hagelbarger theorem, were probably related to analog computers and not a digital machine. Shannon worked for a time on the Differential Analyzer, "the most advanced electromechanical computer in the world." He also notes that H. M. Melvin advanced an alternative proof for this paper in "Journal of Applied Physics," June 1956, pp 658-659. Further research might reveal just what practical application Shannon and Hagelbarger were working on, but we haven't been able to discover it thus far. It is interesting bibliographically that all three forms of this paper (reproduced typescript, Journal of Applied Physics offprint, and Bell Monograph) in Shannon's files were slightly different. The (presumed earliest) reproduced typescript has some apparent typos and incorrectly uses the phrase "concave downward function of the shaft angle" as the desired solution in the first sentence. The Bell Monograph paper corrects that to "concave upward function," as does the Journal of Applied Physics offprint. Lastly, the Journal of Applied Physics offprint includes a second sentence in the first paragraph of Corollary II that starts "This is also true if." which is present in the reproduced typescript but not in the Bell System Monograph. The completist will want one of each. PROVENANCE: The personal files of Claude E. Shannon (unmarked). There were multiple examples of this item in Shannon's files.

COLLECTORS NOTE: The Bell Telephone System Monograph series offered a way to obtain individual articles by Bell scientists regardless of where their work was first published. Many Monographs significantly postdate the original article publication. Because of this, they rarely constitute the coveted (and traditional) article offprint. If the journal of record issued no offprint, the Monograph might be the first separate publication - the closest the collector can come to a traditional offprint. We have done our best to place each Monograph properly in the article's publishing history and welcome any corrections or additional information, especially regarding issues unknown to us.…
