Scipione del Ferro
Born: 6 Feb 1465 in Bologna, Italy
Died: 5 Nov 1526 in Bologna, Italy
Scipione del Ferro is sometimes known as Ferreo, sometimes as Ferro, and sometimes as dal Ferro. His role in the history of mathematics is an important one and he deserves great credit for solving one of the outstanding ancient problems of mathematics. In one sense he is well known, for his role in solving cubic equations is explained in almost every general work on the history of mathematics ever written, and yet, surprisingly, his name remains relatively unknown. Scipione del Ferro's parents were Floriano and Filippa Ferro. Floriano Ferro was employed in paper making which, because of the invention of printing in the 1450s, became an important trade at this time due naturally to a vastly increased demand for paper. Of Scipione del Ferro's education little is known but it is probable that it was at the University of Bologna which was founded in the 11th century and so was a long established and famous university four hundred years before del Ferro was born. We know that del Ferro was appointed as a lecturer in arithmetic and geometry at the University of Bologna in 1496 and that he retained this post for the rest of his life. However he was not only involved in academic activities for records have survived which show that he was involved in business transactions in the latter part of his life.

    La cultura di Golasecca deve il suo nome al luogo dei primi ritrovamenti avvenuti ad opera dell'abate G. B. Giani (1788-1857) sulle colline delle Corneliane, al Monsorino e al Galliasco, nel territorio del comune di Golasecca. Il Giani, eminente studioso locale, ritrovò infatti una cinquantina di tombe con corredi di ceramica e metalli che pubblicò nel 1824 nel libro "La battaglia del Ticino tra Annibale e Scipione". LA NECROPOLI Le nostre conoscenze sulla cultura di Golasecca derivano per lo più dallo studio delle sue necropoli. Nell'area del Ticino il solo rito funebre impiegato era la cremazione, in genere nella forma indiretta. Il defunto era cioè bruciato su un rogo preparato a parte, anche adiacente alla tomba, e le sue ceneri, raccolte dentro un'urna coperta da una ciotola o da pezzi di legno o cuoio, erano poi deposte nella tomba, scavata nella terra.
    Quest'ultima poteva avere le pareti rivestite di ciottoli o lastre di pietra. Caratteristico del comprensorio del Ticino era l'uso di un recinto esterno definito

    Poèiatky jeho kariéry neboli ¾ahké. Roku 1534 dosiahol, že ho v Miláne zamestnali ako lekára mestského chudobinca. Jeden jeho priate¾ ho doporuèil aj do školy pre chudobných, kde vyuèoval matematiku, astronómiu a zemepis. V tomto roku napísal pojednanie o Euklidových Základoch, Ptolemaiovej Geografii a o jednej geometrickej práci anglického scholastika Sacrobosca (1200 - 1256). Roku 1536 prijal do svojho domu za pomocníka štrnásroèného Ludovica Ferrariho , ktorý sa postupne stal jeho žiakom a spolupracovníkom, a neskôr to dotiahol až na profesora matematiky Milánskej univerzity. Roku Cardano dokonèil svoju prácu Praktická aritmetika a jednoduché merania . Vtedy sa dopoèul, že Scipione del Ferro, profesor matematiky na univerzite v Bologni, a Niccolo Fontana, poètár z Brescie, objavili postup na riešenie rovnice tretieho stupòa. Ve¾mi túžil uvies vo svojej knihe tento výsledok, lebo jeho Praktická aritmetika bola kritikou Summy Luca Pacoliho, ktorý tvrdil, že riešenie rovníc tretieho stupòa je nemožné. Avšak Cardano sám nájs riešenie nedokázal, a Fontana nebol ochotný svoje tajomstvo vyzradi. Cardanova kniha preto vyšla bez tohto výsledku v roku

He only solved one of the two cases (the fact that and negative numbers were not in use made many distinct cases). He kept his discovery secret and only told his student Fior shortly before his death. Ferrari reports seeing a notebook in del Ferro's handwriting where the solution is clearly written down.

    L'Histoire des Equations du 3° degré Les Grecs Ils utilisaient une méthode géométrique (intersection de deux coniques) pour résoudre les équations du 3° degré. Ils arrivèrent à la conclusion que les solutions des équations du 3° degré sont les points d'intersection d'une parabole avec une hyperbole. Les Arabes Omar Al Khayyam tenta de résoudre les équations du 3° degré par décomposition et recomposition de cubes; mais ce qui avait été possible deux siècle plus tôt dans le plan avec les équations du 2° degré s'avérait impossible dans l'espace. Devant cette impasse algébrique, il utilisa une autre méthode géométrique pour résoudre les problèmes du 3° degré. La Renaissance Italienne Vers , l'invention de l'imprimerie par Gütemberg fit faire un pas de géant à la propagation des idées... Paccioli Luca En , le moine franciscain Paccioli a imprimé le premier livre d'algèbre intitulé la " Summa ". Il y reprit tous les travaux des Arabes. On y retrouve donc la résolution complète des équations du premier et deuxième degré. Il pensait que les équations du 3° degré étaient insolubles par la méthode algébrique. De il enseigna les mathématiques à l'université de Bologne. Il y rencontra un autre professeur de mathématique : Scipione del Ferro. Il lui fit part de sa conviction sur l'insolubilité des équations du 3° degré. C'est alors que Scipione s'intéressa au problème.
