Também não se usava os números negativos e, portanto não se sabia que as quadráticas tinham duas soluções. Filho de Floriano, empregado de uma fábrica de papel, e de Filippa Ferro. Pouco se sabe sobre a sua educação mas deve ter estudado na Universidade de Bolonha, uma das mais antigas e tradicionais universidades medievais. Sabe-se que foi nomeado professor de aritmética e geometria dessa universidade (1496), ali permanecendo pelo resto da vida. Nos anos de 1501 e 1502 Ferro conheceu Pacioli pois eram os dois professores na universidade de Bolonha. Nessa altura, Pacioli afirmava ser impossível a solução da cúbica . Ferro iniciou então a sua pesquisa para obter a resolução da cúbica tendo obtido bons resultados. Os seus escritos não chegaram aos nossos dias, mas sabe-se que o seu caderno de anotações foi passado, após a sua morte em Bolonha, ao seu genro, Hannibal della Nave, que o teria mostrado a

Extractions: Erase el siglo XVI, en la Italia renacentista, tres notable matemáticos conocidos como Del Ferro, Tartaglia y Cardano, que trabajaban arduamente en busca de encontrar un método práctico para resolver una ecuación matemática, conocida como de tercer grado. Desde la época de los babilonios, 2500 a.d.C.,cuando estos ya conocían la solución de las ecuaciones de segundo grado, (para aplicarlo a sus construcciones) y hasta esa fecha no hubo avances significativos con respecto a este tema. Unos cuántos años antes los famosos matemáticos medievales Fibonacci y Luca Pacioli, habían tratado someramente estos problemas, pero sólo resolviendo algunos casos particulares, e inclusive sin llegar a una demostración racional de tales soluciones. Sería Scipione del Ferro, hijo de un imprentero de Bolonia, el primero en estudiar con un método ortodoxo, la obtención de las raíces (soluciones) de estas funciones matemáticas. Más tarde otras grandes figuras continuarian con estos trabajos, pero sin antes, atravesar un dificil camino de encuentros violentos, dramáticos y deshonestos, por el afán de lograr la primacía en la concrención de sus búsqueda. A través de sus biografía se reflejará esta historia de tristes disputas, y que muestra también la pasión que dominaba a estos genios de los números, que muchas veces viviendo en un ámbito de miserias humanas y materiales , no se dejaban vencer por la adversidad, y siempre se esforzaban para llegar a conocer la verdad de estos dificultosos problemas.

The forces of nature had turned against the city at a most inopportune moment. Ah ... Venice. The streets were filled with that thick mud which clings to ones sandals like a dull slippery weight. Still, there was an enormous crowd gathered in St. Mark's Square ringing the Opera House. And though the auditorium was filled, the overflow crowd lingered outside in the rain waiting ... not for the beautiful sounds of arias, but for news of a contest of wits and wills. Inside the auditorium the noise was deafening. As the arch-deacon rose slowly from his chair in the middle of a bank of chairs to the left side of the stage and rang the bell, a hush fell over the audience. The arch-deacon, acting as master of ceremonies, introduced the competitors, Nicoli Tartaglia and Antonio Maria Fiore, who sat at tables covered with books and papers in the middle of the stage. Tartaglia said nothing, simply nodding his bushy head of unkempt hair to the introductory remarks. Fiore walked out to the apron of the stage and thanked the organizers and the arch-deacon for his generous words of introduction. Tartaglia, who looked more like a bear than a man, appeared to be upset, nervous and pale. Fiore seemed more self assured... Complete the story above in narrative style.

His major work, De subtilitate rerum (1550), on natural history, is perceptive and implies a grasp of evolutionary principles. His book on games of chance represents the first organized theory of probability. Cardano described a tactile system similar to Braille for teaching the blind and thought it possible to teach the deaf by signs.

One such scholar was Girolamo Cardano, known in English as Jerome Cardan. Cardan's basic source of income was his work as a physician, but he was also at various times a professor of mathematics at the universities of Milan, Pavia, and Bologna. Other sources of income included gambling and astrology; however, he was imprisoned for heresy after he cast Christ's horoscope. Cardan's reputation as a mathematician is deservedly great, but marred by scandal. His 1545 work

Extractions: The existing knowledge of both arithmetic and algebra came to Western Europe through the study of Arab mathematics. But not until the fifteenth century were symbols used, as Diophantus had done, for the commonest arithmetical operations. About that time, the symbols and for plus and minus were usual in Italy and France. They had been introduced by Lucia Pacioli (1445-1514) as abreviations for the words piu (more) and meno ( less). The symbols + and - occurred in Germany in 1480. These symbols were first to be printed in 1489 in a book by the Rechenmeister Johan Widmann. The symbols and for multiplication and division do not appear until the 17th century. At this time, the sign for equality caught on, although it occurs earlier in an algebra textbook by the englishman Robert Recorde (1510-58), which appeared in 1557. Recorde introduced the sign with the justification that no two things can be more equal than a pair of parallel lines. Albert Girard (1595-1632) seems to have been the first to give negative solutions full recognition. Also, the interpretation of negative numbers as line segments in the opposite direction was taken up again. However a precise foundation for the arithmetic of negative numbers had to wait until the beginning of the nineteenth century. Complex numbers were used from the 16th century, initially to aid in the solution of cubic equations, but these were viewed with even more scepticism.

The Babylonians knew how to solve the equation ax^2+bx+c=0. Omar Khayyam (1048-1131) devised methods of solving cubic equations through the use of geometric constructions and conic sections. The algebraic solution of the general cubic equation ax^3+bx^2+cx+d=0 was not discovered until the sixteenth century. An Italian mathematician, Luca Paciola (ca. 1445-1509), wrote in Summa de Arithmetica that the solution of the cubic was impossible. This was taken as a challenge by the rest of the mathematical community.

(Les troupes françaises étaient menées par le terrible Gaston de Foix, surnommé "foudre d'Italie".) On raconte que le père de Niccolo (Fontana) avait engagé un professeur pour instruire son fils de 6 ans et que celui-ci arrêta les cours (-après la mort de Monsieur Fontana-) alors qu'il ne lui avait enseigné qu'un tiers de l'alphabet (de A à I). Il poursuivit seul son apprentissage. "Tout ce que je sais, je l'ai appris en travaillant sur les œuvres d'hommes défunts", disait-il. Cependant il est surtout célèbre par la découverte d'une méthode de résolution des équations du 3° degré ; cette découverte, faite en 1537, fut dévoilée à Cardan en 1539 et c'est celui-ci qui la diffusa (on lui donne le nom de "méthode de Cardan" encore aujourd'hui dans les livres de premier cycle universitaire).
