Giuseppe Peano
Giuseppe Peano (Spinetta di Cuneo, 27 agosto 1858 – Torino, 20 aprile 1932) è stato un matematico, logico e glottoteta italiano.
Fu l'inventore del latino sine flexione, una lingua ausiliaria internazionale derivata dalla semplificazione del latino classico.
A lui è intitolato il nostro Istituto.
Per presentarlo ci sembra utile pubblicare l'abstract di una tesina curata da F. Buscaglia per l'Esame di Stato 2008. Ringraziamo l'autore per la disponibilità.
Giuseppe Peano was born 27th August 1858 Cuneo, Piedmont (Former Kingdom of Sardinia) and died 20 April 1923 in Turin.
In 1886, he began teaching concurrently at the Royal Military Academy, and was promoted to Professor First Class in 1889. In that year he published the Peano axioms, a formal foundation for the collection of natural numbers. The Peano curve was published in 1890 as the first example of a space filling curve which demonstrated that the unit interval and the unit square have the same cardinality. Today it is understood to be an early example of what is known as a fractal.
In 1898 he presented a note to the Academy about binary numeration and its ability to be used to represent the sounds of languages. He also was the founder of symbolic logic and his interest centred on development of a formal logical language he called “Sine Flexione”, in Latin.
By 1901, Peano was at the peak of his mathematical career. He had made advances in the areas of analysis, foundations and logic, made many contributions to the teaching of calculus and also contributed to the fields of differential equations and vector analysis. Peano played a key role in the axiomatization of mathematics and was a leading pioneer in the development of mathematical logic.
He died in 1932. Our school was named after him.

Giuseppe Peano
Giuseppe Peano (Spinetta di Cuneo, 27 août 1858- Turin, 20 avril 1932) a été un mathématicien, logicien et idéolinguiste italien.
Il a étudié au lycée classique Cavour de Turin et il a obtenu un diplôme en mathématiques. À l’université de Turin, il est devenu assistant de Angelo Genocchi de 1881 à 1884. Avec le Professeur Genocchi, il a élaboré le traité « Calcolo differenziale e principi di calcolo integrale » qui a été jugé par Paul Maison, dans le journal « Mathesis » comme « un ouvrage excellent ; les principes de l’analyse infinitésimale y sont exposés avec une rigueur et une clarté remarquables ».
Dans la période suivante de nombreux livres et traités de géométrie et mathématiques et surtout des réfutations et des critiques aux traités de Camille Jordan, Guillaume-Jules Hoüel, Hermite, Hermann Laurent, Joseph Bertrand e Isaac Todhunter, ont été publiés.
Grace aux études de Peano, la méthode de calcul vectoriel s’est diffusée au niveau international.
De 1886 jusqu’à 1901 il a enseigné à l’Académie Militaire de Turin.
Il est devenu professeur de calcul infinitésimal depuis 1890 et plusieurs fois il a été révoqué parce que ses études de calcul étaient tellement importantes pour lui, qu’il oubliait de se présenter aux sessions d’examen.
En 1885 il rejoint le groupe maçonnique de la loge de Dante Alighieri de Turin guidé par le socialiste Giovanni Lerda.
Il est décédé le 20 avril 1932 à cause d’une crise cardiaque dans sa résidence de campagne à Cavoretto.
L’interlangue
Il est l’inventeur d’une nouvelle langue internationale qui vient de la simplification du Latin classique : le « Latino Sine Flexione ». Malheureusement ce nouveau langage n’a pas connu beaucoup de succès.
Découvertes scientifiques :
Il a défini le concept de limite supérieur et modifié la définition de courbe. Le nouveau modèle de courbe s’appelait « Courbe de Peano ».
Giuseppe Peano est considéré comme l’un des pères du calcul vectoriel.
Il a aussi écrit un Formulaire Mathématique de plus de 4000 théorèmes et formules démontrés. Ce texte a été écrit d’abord en français et puis en Latino Sine Flexione.
Ses études et contributions ont été fondamentales pour le monde de l’arithmétique, de la logique et de la science. Pour cette raison notre lycée et beaucoup d’autres portent son nom.

Giuseppe Peano
Giuseppe Peano (Spinetta di Cuneo, 27. August 1858 - Turin, 20. April 1932) war ein italienischer Mathematiker, Logiker und Sprachwissenschaftler.
Er war der Erfinder von der lateinischen “sine flexione”, einer internationalen Hilfssprache, die aus der Vereinfachung des klassischen Lateins entsteht.
Außerdem, gab er mit der Peano-Kurve die Definition der Obergrenze an und damit einer raumfüllenden Kurve.
Zusammen mit Tullio Levi-Civita war er auch einer der Väter der Vektorenberechnung. Er demonstrierte wichtige Eigenschaften gewöhnlicher Differentialrechnungen und entwickelte eine Integrationsmethode durch sukzessive Annäherungen.
Er gab eine Definition der natürlichen Zahlen, der berühmten „Peano-Axiome“, die dann von Russel und Whitehead in ihrer „Principia Matematica“ aufgegriffen wurden, um die Typentheorie zu entwickeln.
Unser Gymnasium wurde nach ihm benannt.
