Home page Calcolo combinatorio Esercizi risolti Esercizi proposti I numeri a k b n-k , ovvero il numero di volte che si deve scegliere a tra gli n b . Basta applicare la formula del binomio di Newton con a=b= 1. Questa formula ha un importante applicazione. Dato infatti un insieme E di n n n elementi. Si veda cliccando qui una dimostrazione alternativa, basata sulle disposizioni, dello stesso fatto. . Anche qui basta applicare la formula del binomio di Newton con a =1 e b Considerato un insieme E di n elementi, fissiamo un suo elemento, diciamolo a , e contiamo i sottoinsiemi di k elementi separando, nel conteggio, quelli che contengono a da quelli che non lo contengono. I primi sono C n ,k , in quanto basta scegliere k -1 elementi tra gli n -1 diversi da a e poi aggiungere a . I secondi sono, ovviamente C n ,k . Se ne deduce che . Questo risultato, noto come Formula di Stifel (Michael Stifel, 1487-1567, Arithmetica Integra ), si poteva trarre anche per calcolo diretto: Consideriamo ora due insiemi A e B n ed m . Se S C n+m,k rappresenta il numero dei suoi sottoinsiemi di k elementi. Questi sottoinsiemi si costruiscono prendendo

Les techniques et les innovateurs Les Grands Mathématiciens de la Sidérurgie Ces grands mathématiciens ont fait que nous pouvons différencier le fer, la fonte et l'acier. En 1786, Berthelet, Monge et Vandermonde, trois savants Français, établirent la définition exacte du trio : FER-FONTE-ACIER et le rôle du carbone dans l'élaboration et les caractéristiques de ces trois matériaux. Vandermonde Alexandre français, 1735-1796 Ami de Monge, ce savant, chimiste et mathématicien, entre à l'Académie des sciences à 36 ans suite à ses travaux sur la résolution des équations algébriques de degré au moins égal à 4. Il fut, dans la recherche des solutions de l'équation du 4e degré, un précurseur de ce que l'on nommera, avec Jordan et Galois, la théorie des groupes de substitution Vandermonde est à l'origine de la création du C onservatoire des Arts et Métiers (fondé par la Convention en 1794). Ses autres travaux portent essentiellement sur les équations linéaires.

Overview Page Article Addenda Chronology Carnot's France Britain and Venice Steered the French Revolution Carnot's General System for Military Operations ... Editors' Note: Lyndon H. LaRouche, Jr., during his 1996 campaign for the Democratic Presidential nomination, frequently referred to the conceptions of the great French military strategist Lazare Carnot, as an example of the kind of approach that is needed today to achieve victory over the British-backed forces of oligarchism and usury. At an EIR seminar on July 17, for example, LaRouche described his own campaign to impeach Tom Ridge, the Republican governor of Pennsylvania, whose cuts in medical and social service budgets amount to a Nazi-style crime against humanity. LaRouche introduced the campaign with reference to Carnot: ``Back in 1793, France, under a

The Zen of Magic Squares, Circles, and Stars: An Exhibition of Surprising Structures Across Dimensions Clifford A. Pickover Princeton University Press, 2002 "A refreshing new look at a timeless topic, brimming over with ideas, littered with surprising twists. Anyone who loves numbers, anyone who enjoys puzzles, will find The Zen of Magic Squares, Circles, and Stars compulsive (and compulsory!) reading." Ian Stewart, University of Warwick Order from Amazon.com. "At first glance magic squares may seem frivolous (Ben Franklin's opinion, even as he spent countless hours studying them!), but I think that is wrong. The great nineteenth-century German mathematician Leopold Kronecker said 'God Himself made the whole numberseverything else is the work of men,' and Cliff Pickover's stimulating book hints strongly at the possibility that God may have done more with the integers than just create them. I don't believe in magic in the physical world, but magic squares come as close as we will probably ever see to being mathematical magic." - Paul J. Nahin, University of New Hampshire, author of Duelling Idiots and Other Probability Puzzlers
