Pietro Cossali
Pietro Cossali (29 June 1748 — 20 December 1815) was an Italian mathematician, physicist and astronomer. From 1787 to 1805, he taught physics at the University of Parma. In 1805, Napoleon named Cossali a professor of higher calculus at the University of Padua.Joseph W. Dauben, Christoph J. ScribWriting the History of Mathematics: Its Historical Development 3.5.1. Pietro Cossali, p. 69-70 From 1797 to 1799, he wrote ''Origin, Transmission to Italy, and Early Progress of Algebra There'' ( it, Origine, transporto in Italia, primi progressi in essa dell'algebra), in which he describes mathematical achievements from the emergence of algebra due to Fibonacci to the new research on '' casus irreducibilis'' in the 18th century. This work can be considered the first professional text on the history of Italian mathematics. In this work, Cossali corrects some factual mistakes made earlier by Jean Paul de Gua de Malves, John Wallis and Jean-Étienne Montucla, although h ...

Sant'Anastasia (Verona)
Sant'Anastasia is a church of the Dominican Order in Verona, northern Italy. In Gothic style, it is located in the most ancient part of the city, near the Ponte Pietra. History The current church was started in 1280 and completed in 1400, designed by the Dominican friars Fra' Benvenuto da Imola and Fra' Nicola da Imola. It took its name from a pre-existing temple built by King Theoderic the Great upon which was built the actual church. Since 1307, it is in fact co-entitled to St. Peter of Verona, martyr and co-patron of the city. Consecrated only in 1471, until 1808 the church was held by the Dominicans. The 72 m tall belltower had four bells in 1460, the fifth was added in 1650. In the 1839, the 9 bells were cast and tuned in C; they are rung in Veronese bellringing art by a local team founded in 1776. The church is similar in structure to the Basilica of San Zanipolo in Venice. Façade The façade is divided into three vertical section corre ...

Napoleon
Napoleon Bonaparte ; it, Napoleone Bonaparte, ; co, Napulione Buonaparte. (born Napoleone Buonaparte; 15 August 1769 – 5 May 1821), later known by his regnal name Napoleon I, was a French military commander and political leader who rose to prominence during the French Revolution and led successful campaigns during the Revolutionary Wars. He was the ''de facto'' leader of the French Republic as First Consul from 1799 to 1804, then Emperor of the French from 1804 until 1814 and again in 1815. Napoleon's political and cultural legacy endures to this day, as a highly celebrated and controversial leader. He initiated many liberal reforms that have persisted in society, and is considered one of the greatest military commanders in history. His wars and campaigns are studied by militaries all over the world. Between three and six million civilians and soldiers perished in what became known as the Napoleonic Wars. Napoleon was born on the island of Corsica, not long af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Luca Pacioli
Fra Luca Bartolomeo de Pacioli (sometimes ''Paccioli'' or ''Paciolo''; 1447 – 19 June 1517) was an Italian mathematician, Franciscan friar, collaborator with Leonardo da Vinci, and an early contributor to the field now known as accounting. He is referred to as the father of accounting and bookkeeping and he was the first person to publish a work on the double-entry system of book-keeping on the continent. He was also called Luca di Borgo after his birthplace, Borgo Sansepolcro, Tuscany. Several of his works were plagiarised from Piero della Francesca, in what has been called "probably the first full-blown case of plagiarism in the history of mathematics". Life Luca Pacioli was born between 1446 and 1448 in the Tuscan town of Sansepolcro where he received an abbaco education. This was education in the vernacular (''i.e.'', the local tongue) rather than Latin and focused on the knowledge required of merchants. His father was Bartolomeo Pacioli; however, Luca Pacioli was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Étienne Montucla
Jean-Étienne Montucla (5 September 1725 – 18 December 1799) was a French mathematician and historian. Montucla was born at Lyon, France. In 1754 he published an anonymous treatise on quadrature, ''Histoire des recherches sur la quadrature du cercle''. Montucla's deep interest in history of mathematics became apparent with his publication of ''Histoire des Mathématiques'', the first part appearing in 1758. According to George Sarton, the ''Histoire'' is :a history of the mathematical sciences, and might almost be called a history of science from the mathematical angle, even as many histories of medicine are to some extent histories of science written from the medical angle. He was appointed intendant-secretary of Grenoble in 1758, secretary to the expedition for colonizing Cayenne in 1764, and chief architect and censor-royal for mathematical books in 1765. In 1778 he re-edited Jacques Ozanam's ''Recreations mathématiques'', afterwards published in English by Charles Hutton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Wallis
John Wallis (; la, Wallisius; ) was an English clergyman and mathematician who is given partial credit for the development of infinitesimal calculus. Between 1643 and 1689 he served as chief cryptographer for Parliament and, later, the royal court. He is credited with introducing the symbol ∞ to represent the concept of infinity. He similarly used 1/∞ for an infinitesimal. John Wallis was a contemporary of Newton and one of the greatest intellectuals of the early renaissance of mathematics. Biography Educational background * Cambridge, M.A., Oxford, D.D. * Grammar School at Tenterden, Kent, 1625–31. * School of Martin Holbeach at Felsted, Essex, 1631–2. * Cambridge University, Emmanuel College, 1632–40; B.A., 1637; M.A., 1640. * D.D. at Oxford in 1654 Family On 14 March 1645 he married Susanna Glynde ( – 16 March 1687).

Jean Paul De Gua De Malves
Jean Paul de Gua de Malves (1713, Malves-en-Minervois (Aude) – June 2, 1785, Paris) was a French mathematician who published in 1740 a work on analytical geometry in which he applied it, without the aid of differential calculus, to find the tangents, asymptotes, and various Mathematical singularity, singular points of an algebraic curve. He further showed how singular points and isolated loops were affected by conical projection. He gave the proof of Descartes's rule of signs which is to be found in most modern works. It is not clear whether Descartes ever proved it strictly, and Isaac Newton, Newton seems to have regarded it as obvious. De Gua de Malves was acquainted with many of the French philosophes during the last decades of the Ancien Régime. He was an early, short-lived, participant, then editor (later replaced by Diderot) of the project that ended up as the ''Encyclopédie''. Condorcet claimed that it was in fact the de Gua who recruited Diderot to the project, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casus Irreducibilis
In algebra, ''casus irreducibilis'' (Latin for "the irreducible case") is one of the cases that may arise in solving polynomials of degree 3 or higher with integer coefficients algebraically (as opposed to numerically), i.e., by obtaining roots that are expressed with radicals. It shows that many algebraic numbers are real-valued but cannot be expressed in radicals without introducing complex numbers. The most notable occurrence of ''casus irreducibilis'' is in the case of cubic polynomials that have three real roots, which was proven by Pierre Wantzel in 1843. One can see whether a given cubic polynomial is in so-called ''casus irreducibilis'' by looking at the discriminant, via Cardano's formula. The three cases of the discriminant Let : ax^3+bx^2+cx+d=0 be a cubic equation with a\ne0. Then the discriminant is given by : D := \bigl((x_1-x_2)(x_1-x_3)(x_2-x_3)\bigr)^2 = 18abcd - 4ac^3 - 27a^2d^2 + b^2c^2 -4b^3d~. It appears in the algebraic solution and is the square of the pro ...

Fibonacci
Fibonacci (; also , ; – ), also known as Leonardo Bonacci, Leonardo of Pisa, or Leonardo Bigollo Pisano ('Leonardo the Traveller from Pisa'), was an Italian mathematician from the Republic of Pisa, considered to be "the most talented Western mathematician of the Middle Ages". The name he is commonly called, ''Fibonacci'', was made up in 1838 by the Franco-Italian historian Guillaume Libri and is short for ('son of Bonacci'). However, even earlier in 1506 a notary of the Holy Roman Empire, Perizolo mentions Leonardo as "Lionardo Fibonacci". Fibonacci popularized the Indo–Arabic numeral system in the Western world primarily through his composition in 1202 of ''Liber Abaci'' (''Book of Calculation''). He also introduced Europe to the sequence of Fibonacci numbers, which he used as an example in ''Liber Abaci''. Biography Fibonacci was born around 1170 to Guglielmo, an Italian merchant and customs official. Guglielmo directed a trading post in Bugia (Béjaïa) in modern- ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...
