Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - What is the 'archetypal' image that comes to mind when one thinks of an infinite graph What with a finite graph - when it is thought of as opposed to an infinite one What structural elements are typical for either - by their presence or absence - yet provide a common ground for both In planning the workshop on 'Cycles and Rays' it had been intended from the outset to bring infinite graphs to the fore as much as possible. There never had been a graph theoretical meeting in which infinite graphs were more than 'also rans', let alone one in which they were a central theme. In part, this is a matter of fashion, inasmuch as they are perceived as not readily lending themselves to applications, in part it is a matter of psychology stemming from the insecurity that many graph theorists feel in the face of set theory - on which infinite graph theory relies to a considerable extent. The result is that by and large, infinite graph theorists know what is happening in finite graphs but not conversely. Lack of knowledge about infinite graph theory can also be found in authoritative l sources. For example, a recent edition (1987) of a major mathematical encyclopaedia proposes to '. . . restrict [itself] to finite graphs, since only they give a typical theory'. If anything, the reverse is true, and needless to say, the graph theoretical world knows better. One may wonder, however, by how much.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This volume contains the accounts of papers delivered at the Nato Advanced Study Institute on Finite and Infinite Combinatorics in Sets and Logic held at the Banff Centre, Alberta, Canada from April 21 to May 4, 1991. As the title suggests the meeting brought together workers interested in the interplay between finite and infinite combinatorics, set theory, graph theory and logic. It used to be that infinite set theory, finite combinatorics and logic could be viewed as quite separate and independent subjects. But more and more those disciplines grow together and become interdependent of each other with ever more problems and results appearing which concern all of those disciplines. I appreciate the financial support which was provided by the N. A. T. O. Advanced Study Institute programme, the Natural Sciences and Engineering Research Council of Canada and the Department of Mathematics and Statistics of the University of Calgary. 11l'te meeting on Finite and Infinite Combinatorics in Sets and Logic followed two other meetings on discrete mathematics held in Banff, the Symposium on Ordered Sets in 1981 and the Symposium on Graphs and Order in 1984. The growing inter-relation between the different areas in discrete mathematics is maybe best illustrated by the fact that many of the participants who were present at the previous meetings also attended this meeting on Finite and Infinite Combinatorics in Sets and Logic.

46 signed letters [34 TLS, 12 ALS] comprising decades of correspondence between Frederick Gardner Cottrell and various notable figures of his day in U.S. politics, the international science community, and academia. All letters are housed in new archival mylar sleeves. Cottrell was a notable chemist, inventor, and philanthropist, best known today for his invention of the electrostatic precipitator - one of the first inventions to combat air pollution - and his founding of the Research Corporation for Science Advancement, which used the revenue from the electrostatic precipitator to fund further scientific research, and continues to do so today. While best remembered for these feats, Cottrell had a long and influential career both in the U.S. Federal Government and as a science consultant. He was well known nationally and internationally - in industry, in government, and in academia - for his support of and contributions to new ideas and new talent within the scientific community. The letters, which span from 1901-1941, track Cottrell over the course of 40 years, and evidence the many relationships he had over that period with some of the most influential people of the time. These include a letter of introduction from Alexander Graham Bell, a discussion of chemistry with Thomas Edison, replies from two Nobel Prize winning scientists - the discoverer of the noble gasses, William Ramsay, and discoverer of the electron, J. J. Thomson - to Cottrell's request to study in their labs, and exchanges with two presidents, Herbert Hoover and Woodrow Wilson. Other letters show his personal interactions with leading scientists of his day (Robert J. Van de Graaff, Georges Claude, George E. Hale) and heads of industry (Henry L. Doherty, Ivy Lee), and track the path of his career through his time as the director of the Bureau of Mines; to chairman of the Division of Chemistry and Chemical Technology on the National Research Council; to head of the U.S. Department of Agriculture's Fixed Nitrogen Research Lab, and beyond. These letters, the vast majority of which were sent by these notable figures to Cottrell, evidence his expertise, the depth and breadth of his professional interests, and his eagerness to collaborate and share research and ideas, coming together to trace the life of a man whose work was and continues to be consequential to the advancement of science as a whole. CONTENTS: 1-Page TLS from inventor of the telephone Alexander Graham Bell to a Mr. Fish, dated December 20, 1911, introducing Cottrell to him. In Very Good condition. In this letter, Bell is writing in his capacity as Regent of the Smithsonian Institution. On 1331 Connecticut Avenue letterhead. Faintly creased, with mild wrinkling along the edges. Signed in black ink by Bell: "Alexander Graham Bell". 1-page TLS from inventor of the light bulb Thomas Edison to Cottrell dated January 13, 1925, discussing the unexpected results of a past chemistry experiment of his in relation to the generation of ammonia. In Very Good condition. TLS is on Edison's personal letterhead ("From the Laboratory of Thomas A. Edison"). Lightly age toned, with some wrinkling and small closed tears along the top edge. Faintly creased from past folding. Signed by Edison in black ink: "Thos. A. Edison". Includes a lightly soiled 1-page facsimile of Cottrell's reply. 2-page ALS from Nobel Prize winning physicist Joseph John Thomson to an unnamed recipient, likely Cottrell, dated July 6, 1901, discussing the possibility of Cottrell coming to study at Thomson's lab. In Very Good condition. In 1901, Cottrell would have been studying in Europe at the University of Berlin, seeking to study in the laboratory of an accomplished scientist. Thomson was already a figure of some renown for his 1897 discovery of the electron, which represented the first identification of a subatomic particle, and would be awarded the 1906 Nobel Prize in Physics in recognition of his work. ALS is on Cavendish Laboratory, Cambridge letterhead, and shows a faint crease across the middle and light pencil writing in the top margin of the first page. Small red pencil mark beneath letterhead. Signed in black ink by Thomson: "J. J. Thomson". 1-page ALS from Nobel Prize winning chemist William Ramsay to an unnamed recipient, likely Cottrell, dated 14th August, 1901, in which Ramsay says there is no availability for Cottrell to study in his lab. In Very Good condition. As with the letter from J. J. Thomson, Cottrell would have been studying in Europe at the University of Berlin at the time this letter was sent. In 1901, Ramsay was just a few years away from his landmark 1904 discovery of argon, the first identified noble gas, which would earn him the 1904 Nobel Prize in Chemistry and lead to the development of a new section of the periodic table. ALS is lightly toned along the edges, faintly creased, with a similar red pencil mark in the top margin. Signed by Ramsay in black ink: "W. Ramsay". 1-page TLS from U.S. President Herbert Hoover to Cottrell, dated September 17, 1920. In Very Good minus condition. Brief letter of thanks for Cottrell's forwarding another person's letter to Hoover. On Hoover's personal letterhead. Faintly stamped, "Received / 1920 Sep 18 / Interior Department Bureau of Mines / Washington D.C.". Small rust marks and light wrinkling along the top margin; faintly creased. Signed in black ink by Hoover: "Herbert Hoover". Two 1-page TLS's from Herbert Hoover, each part of an exchange with Cottrell. In Very Good condition. Includes a 2-page facsimile of Cottrell's response. First Hoover TLS sent February 5, 1926; Cottrell's response sent February 8, 1926; Hoover's second TLS sent February 12, 1926. In his first letter, Hoover asks Cottrell about the potential improper investigation of a new method of creating aluminum by the Bureau of Mines. In the second letter, Hoover thanks Cottrell for clearing up the issue. Hoover's letters are on Department of Commerce letterhead. Letters show fa.
