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

V tomto roku napísal pojednanie o Euklidových Základoch, Ptolemaiovej Geografii a o jednej geometrickej práci anglického scholastika Sacrobosca (1200 - 1256).

Scipione Del Ferro Italien,1522-1565) Scipione Del Ferro, né le 2 février 1952 à Bologne est quelques fois connu sous le nom de Ferreo ou Ferro ou parfois Dal Ferro. Les parents de Scipione Del Ferro s’appelaient Floriano et Filippa Ferro. Floriano Ferro était employé dans une usine de papier. Grâce à l’invention de l’imprimerie en et une forte demande, le commerce du papier se développa. On en sait peu sur l’éducation de Scipione Del Ferro mais il aurait été étudiant à la célèbre université de Bologne, créée au XI ° siècle. Nous savons qu’il a été nommé conférencier en arithmétique et géométrie à l’université de Bologne en et qu’il garda son poste jusqu’à la fin de sa vie. Il n’était pas seulement mêlé aux activités académiques. D’après les archives, à la fin de sa vie, il était aussi dans les affaires. Il fut l'un des premiers algébristes de la Renaissance à s'intéresser à une méthode fournissant la solution, sous forme de radicaux, de la racine réelle de l'équation du 3° degré. La découverte de cette formule est un immense événement dans l'histoire de équations ! On ne retrouve aucun écrit sur Del Ferro. Ceci doit être dû en partie à son manque d’ambition pour faire connaître ses recherches, préférant les communiquer seulement à quelques amis et étudiants.

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.
