Jacques Ozanam
Jacques Ozanam (16 June 1640, in Sainte-Olive, Ain – 3 April 1718, in Paris) was a French mathematician. Biography Jacques Ozanam was born in Sainte-Olive, Ain, France. In 1670, he published trigonometric and logarithmic tables more accurate than the existing ones of Ulacq, Pitiscus, and Briggs. An act of kindness in lending money to two strangers brought him to the attention of M. d'Aguesseau, father of the chancellor, and he secured an invitation to settle in Paris. There he enjoyed prosperity and contentment for many years. He married, had a large family, and derived an ample income from teaching mathematics to private pupils, chiefly foreigners. His mathematical publications were numerous and well received. ''Récréations'' (published 1694) was later translated into English and is well known today. He was elected a member of the Académie des Sciences in 1701. The death of his wife plunged him into deep sorrow, and the loss of his foreign pupils through the War of t ...

Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Various forms of brackets are used in mathematics, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abraham De Moivre
Abraham de Moivre FRS (; 26 May 166727 November 1754) was a French mathematician known for de Moivre's formula, a formula that links complex numbers and trigonometry, and for his work on the normal distribution and probability theory. He moved to England at a young age due to the religious persecution of Huguenots in France which reached a climax in 1685 with the Edict of Fontainebleau. He was a friend of Isaac Newton, Edmond Halley, and James Stirling. Among his fellow Huguenot exiles in England, he was a colleague of the editor and translator Pierre des Maizeaux. De Moivre wrote a book on probability theory, ''The Doctrine of Chances'', said to have been prized by gamblers. De Moivre first discovered Binet's formula, the closed-form expression for Fibonacci numbers linking the ''n''th power of the golden ratio ''φ'' to the ''n''th Fibonacci number. He also was the first to postulate the central limit theorem, a cornerstone of probability theory. Life Early years Abra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
17th-century French Mathematicians
The 17th century lasted from January 1, 1601 ( MDCI), to December 31, 1700 ( MDCC). It falls into the early modern period of Europe and in that continent (whose impact on the world was increasing) was characterized by the Baroque cultural movement, the latter part of the Spanish Golden Age, the Dutch Golden Age, the French '' Grand Siècle'' dominated by Louis XIV, the Scientific Revolution, the world's first public company and megacorporation known as the Dutch East India Company, and according to some historians, the General Crisis. From the mid-17th century, European politics were increasingly dominated by the Kingdom of France of Louis XIV, where royal power was solidified domestically in the civil war of the Fronde. The semi-feudal territorial French nobility was weakened and subjugated to the power of an absolute monarchy through the reinvention of the Palace of Versailles from a hunting lodge to a gilded prison, in which a greatly expanded royal court could be more easily ...

People From Ain
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

1640 Births
Year 164 ( CLXIV) was a leap year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Macrinus and Celsus (or, less frequently, year 917 ''Ab urbe condita''). The denomination 164 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Formulas For Generating Pythagorean Triples
Besides Euclid's formula, many other formulas for generating Pythagorean triples have been developed. Euclid's, Pythagoras', and Plato's formulas Euclid's, Pythagoras' and Plato's formulas for calculating triples have been described here: The methods below appear in various sources, often without attribution as to their origin. Fibonacci's method Leonardo of Pisa () described this method for generating primitive triples using the sequence of consecutive odd integers 1,3,5,7,9,11,\ldots and the fact that the sum of the first n terms of this sequence is n^2. If k is the n-th member of this sequence then n=(k+1)/2. Choose any odd square number k from this sequence (k=a^2) and let this square be the n-th term of the sequence. Also, let b^2 be the sum of the previous n-1 terms, and let c^2 be the sum of all n terms. Then we have established that a^2+b^2=c^2 and we have generated the primitive triple 'a, b, c'' This method produces an infinite number of primitive triples, but not ...

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] |

Collège De Sorbonne
The College of Sorbonne (french: Collège de Sorbonne) was a theological college of the University of Paris, founded in 1253 (confirmed in 1257) by Robert de Sorbon (1201–1274), after whom it was named. With the rest of the Paris colleges, the Sorbonne was disestablished by decree of 5 April 1792, after the French Revolution. It was restored in 1808 but finally closed in 1882. In recent times it came to refer to the group of liberal arts faculties of the University of Paris, as opposed to the vocational faculties of law and medicine.''Dictionniare historique de Paris'', Le Livre de Poche, 2013 "Sorbonne" is also used to refer to the main building of the University of Paris in the 5th arrondissement of Paris, which houses several faculties created when the University was divided into thirteen autonomous universities in 1970.
