- 1. The most important Italian mathematicians The history of Italian mathematics over the centuries
- 3. LEONARDO FIBONACCI Leonardo Fibonacci, son of Guglielmo Bonacci, was born in Pisa around 1170. His father was responsible for trade in Pisa at the colony of Bugia, in Algeria. A few years after 1192, Leonardo went with his father to Bugia where he learned mathematics. His father wanted Leonardo to become a merchant, so he sent him on a tour to Egypt, Syria, Greece, Sicily and Provence. Fibonacci took the opportunity offered by his travels abroad to study and learn the mathematical techniques used in these regions and collected them in his book "Liber abbaci", published in 1228. He died in Pisa around 1235.
- 4. THE FIBONACCI SEQUENCE The Fibonacci sequence, indicated Fₙ, shows a succession of positive integers in which each number, starting from the third, is the sum of the two previous ones, where the first two are: The elements Fₙ are also called Fibonacci numbers.
- 7. NICCOLO’ TARTAGLIA Niccolò Fontana, also known as Niccolò Tartaglia because of his stuttering, was born in Brescia in 1499. Tartaglia tells that at 13 years old, during the sack of Brescia by the French on 19 February 1512, he took refuge with his family in the old cathedral of Brescia, but they were followed up there and then attacked: Niccolò suffered a fracture of the skull and injuries to the jaw and palate. It is mainly known for the discovery of the numerical triangle called "triangle of Tartaglia", which appears in the book "General treatise on numbers and measures" written in 1556; in 1521 it solved the cubic equation. He died in Venice on 13 December 1557.
- 8. TARTAGLIA’S TRIANGLE The Tartaglia’s triangle is a triangle-shaped table composed of natural numbers, where each number is a particular binomial coefficient. This table has infinite elements and each row is obtained from the previous. Its main application lies in the development of any binomial power:
- 9. CONSTRUCTION OF THE TARTAGLIA’S TRIANGLE: To write the elements that make up the triangle of Tartaglia all the numbers 1 are shown on the top vertex and along the two sides of the triangle; Each element is obtained from the sum of the two numbers of the line above it.
- 11. GALILEO GALILEI Galileo Galilei was born in Pisa on 15 February 1564. He was an Italian physicist, astronomer, philosopher, mathematician and academic, considered the father of modern science. In 1580 he began to study medicine but, a few years later, he decided to specialize in mathematics and to undertake the study of physics.
- 12. Galileo Galilei introduced the experimental scientific method and supported the Copernican theory, for which he was accused of contradicting the Holy Scriptures and was condemned by the Court of the Holy Office. Galileo Galilei is considered an important figure in the Scientific Revolution. He died on 8 January 1642 in Arcetri. THE EXPERIMENTAL SCIENTIFIC METHOD
- 13. GALILEO’S INVENTIONS During his stay in Pisa came to his first discovery, the isochronism of the oscillations of the pendulum. Going on with his studies, he formulates some theorems of mechanics and geometry until he discovers the hydrostatic balance to calculate the specific weight of bodies.12 In 1604 a new star appeared, the Super Nova. This event led him to perfect the telescope, which was used to observe the stars.

- 15. EVANGELISTA TORRICELLIEvangelista Torricelli was born in Rome on 15 October 1608. In Faenza, he went on to study mathematics. In Rome, for many years Torricelli worked and studied with Father Castelli who presented to Galileo his manuscript ‘’De motu gravium’’. On 10 October 1641 Torricelli became Galileo’s assistant. When Galileo died Torricelli became his successor as mathematician of the Grand Duchy of Tuscany. He elaborated several important theorems and anticipated the infinitesimal calculus, he devoted himself to physics studying the motion of gravities and fluids and deepening the optics. He died on 25 October 1647 in Florence
- 16. TORRICELLI’S TUBE Torricelli also dedicated himself to the study of fluids, inventing the mercury barometer called "Torricelli's tube". This invention is based on the measurement of atmospheric pressure by a tube that is filled with mercury up to a constant height of 760mm. mercur y mercur y vacuum 760mm __________
- 17. TORRICELLI’S TRUMPET This instrument has the particularity of having finished volume, but infinite area. infinitely Thanks to the integration formulas we can find: • Volume of solid • Area of solid

- 19. PAOLO RUFFINI Paolo Ruffini was born in Valentano on 22 September 1765. He is famous for his contributions to Algebra and in particular for his polynomial division algorithm. He was an Italian mathematician and physician, obtaining a degree in Philosophy, Medicine, Surgery and Mathematics from the University of Modena in 1788. So from 1797 he was a professor of Mathematics at the same University. When the typhus epidemic of 1817 broke out, he became ill, treating his patients and despite the recovery he had to leave the chair in 1819. He died in Modena on 10 May 1822.
- 20. RUFFINI’S ROULERuffini was responsible for the so called Theorem of Abel-Ruffini (demonstration of the algebraic non solubility of the equations after the fourth degree) and in 1809, the publication of Ruffini's rule. This is a method of dividing polynomials in which the coefficients of polynomials are divided, removing the variables and the exponents, to verify if it is exactly divisible by a binomial.
- 22. VITO VOLTERRA Vito Volterra was born in Ancona on 3 May 1860. He was an Italian mathematician, physicist, politician and anti-fascist. At the age of 13, he calculated the trajectory of a bullet under the effects of the gravitational field of the Earth and the Moon. For two years he devoted himself to partial derivative equations and particularly to cylindrical wave equations. He died in Rome on 11 October 1940. In the University of Pisa, he began the development of the theory of the functional, dealt with the integral equations and the equations integro-differential.
- 23. VOLTERRA’S INVENTIONS • .Functional analysis, is the field of mathematical analysis that deals with the study of spaces of functions; • .Integral equations, every equation that has the unknown under the sign of integral. *
