Rafael Bombelli By Jessica Spencer Biography Rafael Bombelli Rafael Bombelli was born in 1526 in Bologna, Italy. He was the son of Antonio Mazzoli and Diamante Scudier. He was the oldest of six children. Antonio Bombelli changed the family name from Mazzoli to Bombelli after the land which had been taken from the family years before was finally returned to them. The Bentivolio family had originally ruled Bologna. Giovanni Bentivoglio II had done much to improve Bologna, especially in the development of the cities waterways. The Mazzoli family was a supporter of the Benivoglio family. However, in 1506, Pope Julius II took control of Bologna and sent the Bentivoglio family into exile. In 1508 the Bentivoglio family and its supporters attempted to regain control of the city. The coup failed and Rafael Bombelli’s great grandfather was executed along with many other people. Pope Julius II confiscated the Mazzoli land and the family lived in poverty for many years. The land was then returned to Antonio Mazzoli, and that is when he changed his last name to Bombelli Little is actually know about Rafael Bombelli’s life.

Rafaello Bombelli (Italien,1526-1573) Rafael Bombelli, né à Bologne en janvier ne reçut aucune éducation universitaire. Il fût l’élève d’un ingénieur. Architecte Pier Francesco Clémenti, aussi ce n’est peut-être pas étonnant que Rafael en fasse sa passion. Bombelli devint ingénieur et ses nombreux projets furent mis en valeur. Il a travaillé de nombreuses années pour Alessandro Rufini (dernier évêque de Melfi). En , la réparation du pont de Santa Maria à Rome fût un échec. Bombelli fût le premier à additionner et multiplier les nombres complexes. Il démontra, en utilisant ses méthodes, que des solutions réelles aux équations du 3° degré auraient pu être obtenues à partir de la formule de Cardan même lorsque la formule donne une expression qui associe les racines carrées imaginaires des nombres négatifs. En Bombelli écrivit sa seule publication: « Algébra Algébra » ne fût publié qu’à partir de Son livre a permis l’expansion de l’algèbre vers l’univers des nombres complexes.

Bombelli introdusse i termini e meno di meno , per indicare + i e - i , che abbrevia nelle scritture pdm e mdm ; ad esempio, con: R c pdm Nel linguaggio di Bombelli, queste regole si esprimono nel seguente modo: Meno di meno via men di meno, fa meno.

"Llorar por dentro... como dice RAFAEL ANGEL, en este bello poema de su autoría, nos purifica el alma y nos limpia el corazón. Pero en el amor carnal, hay que dejar que ruede esa agua salada cubriendo nuestro rostro, solo así... limpiando nuestros ojos podemos ver con claridad una nueva ilusión." "Para vivir un gran amor, hay que animarse a correr riesgos" ¿Qué es llorar...? Autor: Rafael Angel© Llorar es la salida de lo amargo que guardamos muy profundo cuando hacemos a nuestras almas quejumbrosas y llorosas; cuando ese amor, que es anhelado, lo perdemos. Y es, también, ese sangrar de nuestras venas que nos clava, como flecha, en nuestros huesos. Y también es `un llorar`... una quimera, con un amigo que emprendió ya su regreso. Llorar es maldecir, con justa rabia, cuando un hijo se nos pierde en el desierto de los vicios, de las drogas, de la mafia, y lo vemos terminar con su deceso. Llorar es el cargar en la cajuela por el camino que conduce al camposanto a nuestro padre, a nuestro hermano, a nuestra abuela, o al ser amado... ¡a quien quisimos tanto!

E qual è quella giusta? Proviamo a chiederlo direttamente all’inventore dei numeri complessi. Rafael Bombelli (1526-1572), Matematico bolognese. Utilizzò per primo, nella sua opera principale, L’Algebra quelli che oggi chiamiamo immaginari puri , precisandone le regole di calcolo aritmetico. I numeri complessi nascono dunque come simboli numerici della forma z=a+ib (con a,b numeri reali), per i quali sono così definiti la somma ed il prodotto: a ib a' ib' a a' i b b' a ib a' ib' aa' bb' i ab' a'b Ecco la risposta giusta.
