Scipione del ferro biography of rory gilmore girlfriend

Italian mathematician (–)

Scipione del Ferro (6 February &#; 5 November ) was an Italian mathematician who first discovered a method to solve the depressed cubic equation.

Life

Scipione del Ferro was born in Bologna, in northern Italy, to Floriano and Filippa Ferro.

His father, Floriano, worked in the paper industry, which owed its existence to the invention of the press in the s and which probably allowed Scipione to access various works during the early stages of his life. He married and had a daughter, who was named Filippa after his mother.

He likely studied at the University of Bologna, where he was appointed a lecturer there in Arithmetic and Geometry in During his last years, he also undertook commercial work.

Scipione del ferro biography of rory gilmore wife Scipione del Ferro was a notable Italian mathematician and theorist whose contributions laid the foundation for modern algebra. Born in Bologna, Italy, he is primarily known for his work on solving cubic equations, which was a significant advancement in the mathematical landscape of the Renaissance. His life and work epitomize the transition from medieval mathematics to the more systematic approach that characterized the modern era. Not much is documented about del Ferro's early life, but it is widely believed that he studied in Bologna, a city renowned for its scholarly environment and center of learning during the late 15th century. The patronage from the University of Bologna would have played a crucial role in shaping his mathematical prowess.

Diffusion of his work

There are no surviving scripts from del Ferro. This is in large part due to his resistance to communicating his works. Instead of publishing his ideas, he would only show them to a small, select group of friends and students.

It is suspected that this is due to the practice of mathematicians at the time of publicly challenging one another.

Scipione del ferro biography of rory gilmore The purpose of this blog is to present the story behind Fermat's Last Theorem and Wiles' proof in a way accessible to the mathematical amateur. In distinction this discovery surpasses all mortal ingenuity, and all human subtlety. It is truly a gift from heaven, although at the same time a proof of the power of reason, and so illustrious that whoever attains it may believe himself capable of solving any problem.

When a mathematician accepted another's challenge, each mathematician needed to solve the other's problems. The loser in a challenge often lost funding or his university position. Del Ferro was fearful of being challenged and likely kept his greatest work secret so that he could use it to defend himself in the event of a challenge.

Despite this secrecy, he had a notebook where he recorded all his important discoveries. After he died in , his son-in-law Annibale della Nave inherited this notebook, who was also a mathematician and married to del Ferro's daughter, Filippa. Nave was a former student of del Ferro's, and he replaced del Ferro at the University of Bologna after his death.

In , Gerolamo Cardano and Lodovico Ferrari (one of Cardano's students) travelled to Bologna to meet Nave and learn about his late father-in-law's notebook, where the solution to the depressed cubic equation appeared.

Scipione del ferro biography of rory gilmore girls Scipione del Ferro was an Italian mathematician born in Bologna in He studied at the University of Bologna and graduated with a degree in mathematics. After years of arduous efforts, he discovered a general method to solve this type of equation where p and q are constants. Del Ferro's discovery was groundbreaking. It marked the first time a European mathematician had solved a problem that had eluded the greatest minds of ancient Greece and the Islamic world for centuries.

The solution of the cubic equation

Mathematicians from del Ferro's time knew that the general cubic equation could be simplified to one of two cases called the depressed cubic equation, for positive numbers ,,:

The term in can always be removed by letting for an appropriate constant .

While it is not known today with certainty what method del Ferro used, it is thought that he used the fact that solves the equation to conjecture that solves . This turns out to be true.

Then with the appropriate substitution of parameters, one can derive a solution to the depressed cubic:

There are conjectures about whether del Ferro worked on a solution to the cubic equation as a result of Luca Pacioli's short tenure at the University of Bologna in – Pacioli had previously declared in Summa de arithmetica that he believed a solution to the equation to be impossible, fueling wide interest in the mathematical community.

It is unknown whether Scipione del Ferro solved both cases or not.

However, in , manuscripts were discovered by Bortolotti which contained del Ferro's method and made Bortolotti suspect that del Ferro had solved both cases.

Cardano, in his book Ars Magna (published in ) states that it was del Ferro who was the first to solve the cubic equation and that the solution he gives is del Ferro's method.

Other contributions

Del Ferro also made other important contributions to the rationalization of fractions with denominators containing sums of cube roots.

He also investigated geometry problems with a compass set at a fixed angle, but little is known about his work in this area.

  Biography 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 s, became an important trade at this time due naturally to a vastly increased demand for paper.
