Zustand: Good. De Sportkalender 2007 presenteert de lezer een breed scala aan historische feiten en hilarische momenten, informatie en folklore uit de wereld van de sport in de vorm van anekdotes, beschouwingen, citaten, korte biografie verslagen en ranglijsten. Het uitgangspunt voor de auteurs was de terugblik, waarbij de dagen van het jaar als leidraad hebben gediend.In het overgrote deel van deze kalender worden sportieve gebeurtenissen uit het verre en nabije verleden in herinnering geroepen die zich ooit op diezelfde dag. maar in een ander jaar, hebben voltrokken.De Sportkalender staat niet alleen maar sti bij de mijlpalen,vedetten, grote sporten en mondiale evenementen, ook passeert een keur aan nationale wapenfeiten uit de Nederlandse en Belgische sport de revue. Naast Clay, Crujff en Ceulemans figureren waterdrageers en mislukkelingen. En zelfs obscure sporten, catastrofen, muizenissen en roddelpraat komen aan bod. Vaak in woord beeld, want deze kalender is ge ustreerd met foto's, tekeningen, grafieken en overzichten.Op de koop toe staan er fonkelnieuwe sportstukken in van gastschrijvers als Ad van Liempt, Frank Snoeks, Bert Wagendorp, Jeroen Wielaert en Raf Willems.; Gaaf exemplaar met schoon binnenwerk.

Leipzig, B.G. Teubner, 1912. 8vo. Bound in half cloth with the original printed wrappers. In "Mathematische Annalen. Herausgegeben von A. Clebsch und C. Neumann. 68. Band. 3. Heft." Entire issue offered.Black title-label in leather with gilt lettering to spine. Small library-label pasted on to top of spine. Small library stamp to title page and a few numbers written on front wrapper. Internally very fine and clean. [Brouwer:] Pp. 37-54" Pp. 55-6" Pp. 422-25 [Entire issue: (4), 595 pp.]. First printing of three important papers by Brouwer. In "Zur Invarianz des n-dimensionalen Gebiets" Brouwer introduced his "Invariance of domain" which is a theorem in topology about homeomorphic subsets of Euclidean space."The existence of one-to-one correspondences between numerical spaces Rn for different n, shown by Cantor, together with Peano's subsequent example (1890) of a continuous mapping of the unit segment onto the square, had induced mathematicians to conjecture that topological mappings of numerical spaces Rn would preserve the number n (dimension). In 1910 Brouwer proved this conjecture for arbitrary n." (DSB).

Leipzig, B.G. Teubner, 1911. 8vo. Original printed wrappers, no backstrip and a small nick to front wrapper. In "Mathematische Annalen. Begründet durch Alfred Clebsch und Carl Neumann. 70. Band. 2. Heft." Entire issue offered. Internally very fine and clean. [Brouwer:] Pp. 161-65. [Entire issue: Pp. 161-296]. First printing of Brouwer's "revolutionary" and "landmark" contribution to topology. It marked a new period within topology-research: "Although the paper is short and merely contains a simple proof of the invariance of dimension, "it is infact much more than this - the paradigm of an entirely new and highly promising method now known as algebraic topology". (Aull. Handbook of the history of general topology. P. 150). "The article submitted in June was the momentous "Proof of the invariance of the dimension number". In the following month it was followed with a longer paper, also a masterpiece. Of these two revolutionary papers, [The present paper] used his newly discovered "degree of a mapping" concept implicitly for the proof of dimensional invariance. [the paper] effectively swept away all previous attempts to prove dimensional invariance. (James. History of Topology, P. 16)"Cantor and others offered proofs that, indeed, a continuous mapping of points between dimensions was impossible, but a fully satisfactory proof establishing the invariance of dimension was not provided until the topologist L. E. J. Brouwer did so in 1910". (DSB).
