Fantuzzi says that Bombelli was born to a noble family, but I think that is just conventional talk. None of the other sources bear that out. No information on financial status. 3. Nationality Birth: Bologna, Italy Career: Italy Death: Rome? Italy 4. Education Schooling: No University All that is known about Bomelli's education is that his teacher was Pier Francesco Clementi of Corinaldo, an engineer-architect, who drained swamps. 5. Religion Affiliation: Catholic 6. Scientific Disciplines Primary: Mathematics Bombelli was the last of the algebraists of Renaissance Italy. His only published work, Algebra, gave a comprehensive account of the existing knowledge of the subject, enriching it with Bombelli's own contributions. The influence that his Algebra had in the Low Countries was great. Leibniz called him an "outstanding master of the analytical art." Bombelli worked at reclaiming land and at least one other engineering task, but there is nothing to indicate that he furthered the sciences of hydraulics and engineering.

Complex Numbers 1572 Information From Answers.comThe Algebra of rafael bombelli b. Bologna (Italy), January 1526, d. 1572 showsthe first application of complex numbers to solve equations, http://www.und.edu/instruct/lgeller/complex.html
Extractions: The usual definition of complex numbers is all numbers of the form a+b i , where a and b are real numbers and i , the imaginary unit, is a number such that its square is -1. This gives no insight to where these came from nor why they were invented. In fact, the evolution of these numbers took about three hundred years. In 1545 Jerome Cardan , an Italian mathematician, physician, gambler, and philosopher published a book called Ars Magna The Great Art ). In this he described an algebraic procedure for solving cubic and quartic equations. He also proposed a problem that dealt more with quadratics. He wrote: If some one says to you, divide 10 into two parts, one of which multiplied into the other shall produce...40, it is evident that this case or question is impossible. Nevertheless, we shall solve it in this fashion. Cardan essentially applied the method of completing the square to x + y = 10 and xy = 40 (x - 10x + 40 = 0) to get the numbers,

Mathematics Pietro Cataldi's mathematics in Trattato del modo brevissimo di trovar la radice quadra delli numeri ("treatise on a short way to find the square roots of numbers") introduces more extensive use of continued fractions to Europe. Continued fractions, however, had previously been used by Indian mathematicians and by Rafael Bombelli. Continued fractions are those whose denominators contain fractions that also contain fractions in the denominator and so on for an infinite progression of fractions in the denominator. They are a convenient form for expressing many problems involving limits. See also 1572 Mathematics

Continued Fractions - History Two men from the city of Bologna, Italy, rafael bombelli (bc1530) and PietroCataldi (15481626) also contributed to this field, albeit providing more http://archives.math.utk.edu/articles/atuyl/confrac/history.html
Extractions: To do mathematics, that is, in order to understand and to make contributions to this discipline, it is necessary to study its history. Mathematics is constantly building upon past discoveries. Those who wish to study a particular field of mathematics, whether it be statistics, abstract algebra, or continued fractions, will first need to study their field's past. In doing so, one is able to build upon past accomplishments rather than repeating them. The origin of continued fractions is hard to pinpoint. This is due to the fact that we can find examples of these fractions throughout mathematics in the last 2000 years, but its true foundations were not laid until the late 1600's, early 1700's. The origin of continued fractions is traditionally placed at the time of the creation of Euclid's Algorithm Euclid's Algorithm, however, is used to find the greatest common denominator (gcd) of two numbers. However, by algebraically manipulating the algorithm, one can derive the simple continued fraction of the rational p/q as opposed to the gcd of p and q. (To see this, check out Theorem 1 .) It is doubtful whether Euclid or his predecessors actually used this algorithm in such a manner. But due to its close relationship to continued fraction, the creation of Euclid's Algorithm signifies the initial development of continued fractions.

Architecte Pier Francesco Clémenti, aussi ce nest 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 quà partir de Son livre a permis lexpansion de lalgèbre vers lunivers des nombres complexes.

NOTES TO TEACHER (INCLUDES STANDARDS) Introduction The year is 3003. You have been selected by the government to be a part of a team of researchers to time travel to the past and study the beginnings of modern math. The time period of focus starts with the middle ages and continues through the Renaissance. This was the age of discovery complete with the growth of universities and the leadership of both a Pope and an Emperor. TASK Your team will be assigned a certain mathematician as your subject of research. Each team member with have tasks to fulfill and information to retrieve. Your results when you return will be presented to an audience of your peers and evaluated by them. The central question of your presentation is "How does this mathematician's algebra compare to our prior algebra studies?" Your team will also compile a portfolio to present your findings. Let's get started. Back to top PROCESS Each member of the team will play a different role. You select amongst yourselves to be a Mathematician, a Historian or a Teacher.
