Description
Melbourne, London, Baltimore: Penguin Books, 1954. FIRST EDITION, FIRST PRINTING. Original printed wrappers. First printing. This article constitutes a summary of Turing’s most theoretical work in computer science to date (a year before his death). He here expounds the ideas used in proofs of unsolvability since 1936 and enumerates some of the results and open problems. These include proof of the existence of mathematical problems that cannot be solved by the universal Turing machine. This is a turnabout from his earlier position that “any algorithmic procedure that can be carried out by a human or group of humans can be carried out by some Turing Machine.” Though common sense might say that a universal machine is impossible, Turing proved that it is possible, though later proved that there are mathematical problems which cannot be solved by any systematic method – in other words, be solved by any algorithm. In “Solvable and unsolvable problems” Turing sets out to explain this result to a lay audience. Starting from concrete examples of problems that do admit of algorithmic solution, Turing works his way towards an example of a problem that is not solvable by any systematic method. Loosely put, this is the problem of sorting puzzles into those that will “come out” and those that will not. Turing gives an elegant argument showing that a sharpened form of this problem, which he call the “substitution type of puzzle,” is not solvable by means of a systematic method. Of interest is that his puzzle examples are quite similar to those invented by Lewis Carroll in his Doublets: a word puzzle (first published in London, 1879). Turing suggests that any puzzle can be re-expressed as a substitution puzzle. Some row of letters can always be used to represent the “starting position” envisaged in a particular puzzle, e.g. in the case of a chess problem, the pieces on the board and their positions. Desired outcomes, for example board positions that count as wins, can be described by further rows of letters, and the rules of the puzzle, whatever they are, are to be represented in terms of permissible substitutions of groups of letters for other groups of letters. It is much easier to understand by reading the article than by reading this description. See Turing, Alan, ‘Solvable and Unsolvable Problems (1954)’, in Copeland (ed.), The Essential Turing (Oxford, 2004; online edn, Oxford Academic, 12 Nov. 2020), https://doi.org/10.1093/oso/9780198250791.003.0024, accessed 22 Sept. 2023.

Description
small quarto, one page, formerly folded, in very clean, legible condition, fine. Jean Baptiste Charles Henri Hector, comte d’Estaing, French general and admiral who fought in the American War for Independence. He began his service as a soldier in the Seven Years War, spending time as a prisoner of war of the British. Following the entry of France into the Revolutionary War in 1778, he led a fleet to aid the American rebels, and participated in failed Franco-American attacks on Rhode Island and the Siege of Savannah. He returned to France in 1780. D’Estaing was subsequently executed in the Reign of Terror during the French Revolution. The letter reads: “On ne peut être, Monsieur, plus flatté que je le suis des marques d’amitiés et de souvenir que vous avés la bonté de me donner; vous êtes assurément du nombre de ceux qu’on n’oublie point lorsqu’on s’eu l’honneur de les connaitre; la reconnaissance m’y oblige, les marques d’amitiés que vous avez bien voulu me donner sur le Superbe me sont toujours présentes; je partage bien sincèrement nos regrets sur notre ami commun, pénétré comme je le dois de tout ce que vous me marques; je n’en fais trop de cas pour n’en pas proffitter de ce que je ne prevois nullement aravit; soyeé persuadé de la vérité de ces deux choses. Je suis à Calais, et à Dunkerque ce n’est pas le chemin de Brest, ce n’est même-celui de nul part, ainsi j’imagine que je ne serai de longtemps dans le cas heureux de loger chez vous et d’augmenter les obligations que je vous ai déjà croyés que je choisirai toujours les- occasions de me raprocher de vous renouveller tous les sentiments avec lesquels j’ai l’honneur d’être. …”

A near-fine copy; corners slightly bumped
Description
Paris: Flammarion, 2006. A near-fine copy; corners slightly bumped. 11.25 x 8.25 inches. 207 pages. Profusely illustrated in color. Original pink, die-cut boards. First edition. "Internationally acclaimed Swiss artist John Armleder fuses genres and media; he borrows influences from modernist art, modern design, constructivism, art deco, minimalism, op art, music, and film. The resulting images, sculptures, and installations often involve the viewer's active participation; his art is as much experienced as it is viewed. This comprehensive book charts Armleder's career with an interview, an analytical retrospective text, and 150 images, which presents the artist's eclectic output from his early work to his current projects. Armleder's work is widely exhibited in international galleries and museums. He recently curated the exhibition None of the Above (winter 2004-05) at the Swiss Institute of Contemporary Art in New York. A solo exhibition of his work opened in May 2005 at the Cosmic Galerie in Paris" (the publisher).
