Wraps. Zustand: Near Fine. First Separate Edition. First Separate Edition. [42]-43 pages. 10 1/2 x 7 3/4 inches. Publisher's original tan printed wrappers. Sun fading to the rear panel. 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 (as here). Also later printed in the Bell Telephone Systems Monograph Series (#2547: March 1956). 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.

Bright and clean internally. Wrappers. The Nobel Prize in Physics 1995 was awarded jointly "for pioneering experimental contributions to lepton physics" to Martin L. Perl "for the discovery of the tau lepton" and Frederick Reines "for the detection of the neutrino." In 1953 Reines and Cowan published "Detection of the Free Neutrino" (Physical Review 92, p830) where they noted "An experiment has been performed to detect the free neutrino. It appears probable that this aim has been accomplished although further confirmatory work is in progress." The further work took three years, when in 1956, Cowan, et al published "Detection of the Free Neutrino: A Confirmation" (Science 124) confirming the previous work. That same year, Reines and Cowan published "The Neutrino" (Nature 178, p 446) with a history of work done to date and some new experimental results. While Ezhela notes the paper offered here provides "Confirmation of the detection of the anti v(sub e) [i.e. anti-neutrino]" and it clearly is related to their earlier work ("identical in principle with that performed at Hanford in 1953"), the paper offered here is focused on a refinement in results to further confirm the work done in 1953 and 1956. Reines and Cowan reported that in 1956 an approximate value for the absoprtion cross section essential to the theory of the reaction predicted. This experiment modified the equipment used in order to "obtain a better value of the cross section." See Ezhela, Particle Physics One Hundred Years of Discoveries, "Reines 1953B", p125; "Cowan 1956" and "Reines 1956" p146-7; and "Reines 1959", p. 169 See also The Physical Review - the First Hundred Years, pp 807-8 and 866 (this paper),

Contains 'Absence of Diffusion in Certain Random Lattices' IN The Physical Review, Vol 109, Second Series, Number 5, March 1, 1958, pages 1492-1505. Wrappers. 'This paper presents a simple model for such process as spin diffusion or conduction in the impurity band. These processes involve transport in a lattice which is in some sense random, and in them diffusion is expected to take place via quantum jumps between localized sites. In this simple model the essential randomness is introducted by requiring the energy to vary randomly from site to site. It is shown that at low enough densities no diffusion at all can take place, and the criteria for transport to occur are given.' (abstract) 'One of the more subtle electronic features of real materials is the distinction between continuum electronic states and conducting electronic states. The fact that continuum electronic states in band tails might be localized was recognized by P. W. Anderson [Phys. Rev. 109, 1492 (1958)] in a paper that appeared just about the time superconductivity was being explained.' (The Physical Review, The First Hundred Years, a Selection of Seminal Papers and Commentaries, p. 621) Also contains articles by Sudarshan and Marshak about Fermi interaction as well as Lee, Yang and others. The Nobel Prize in Physics 1977 was awarded jointly to Philip Warren Anderson, Sir Nevill Francis Mott and John Hasbrouck van Vleck "for their fundamental theoretical investigations of the electronic structure of magnetic and disordered systems".

A clean copy, noting some shallow puncture marks and deeper impressions to the first 45 pages from what looks like staple impressions (storage on box bottom?).

Contains 'New Phenomena in Narrow Germanium p-n Junctions' . The Nobel Prize in Physics 1973 was divided, one half jointly to Leo Esaki and Ivar Giaever "for their experimental discoveries regarding tunneling phenomena in semiconductors and superconductors, respectively and the other half to Brian David Josephson "for his theoretical predictions of the properties of a supercurrent through a tunnel barrier, in particular those phenomena which are generally known as the Josephson effects". "To date.the materials that have most profoundly affected our daily lives are semiconductors. Of considerable interest during the 1930s and 1940s, the recognition of their utility in microelectronic devices has led to sensor, computer, and communication technologies. May such uses have their origin in transistors.[and] the development of the integrated-circuit microelectronic devices that have led to the silicon revolution.represented by the work of Esaki [Phys Rev 109, 603 (1958)] on the tunneling diode and the work of Esaki and Chang (Phys Rev Lett. 33, 495 (1974))] on hetereostructures."
