full_context: Document 1: Colsterworth: Colsterworth is a village and civil parish in the South Kesteven district of Lincolnshire, England. It lies less than half a mile (0.8 km) west of the A1, about 7 mi south of Grantham, and 12 mi north-west of Stamford. The village, with the hamlet of Woolsthorpe-by-Colsterworth, had a population of 1,713 at the time of the 2011 Census in an area of 1465 ha .
Document 2: Jacob Bernoulli: Jacob Bernoulli (also known as James or Jacques; 6 January 1655 [O.S. 27 December 1654] – 16 August 1705) was one of the many prominent mathematicians in the Bernoulli family. He was an early proponent of Leibnizian calculus and had sided with Leibniz during the Leibniz–Newton calculus controversy. He is known for his numerous contributions to calculus, and along with his brother Johann, was one of the founders of the calculus of variations. He also discovered the fundamental mathematical constant e. However, his most important contribution was in the field of probability, where he derived the first version of the law of large numbers in his work "Ars Conjectandi".
Document 3: Newton's identities: In mathematics, Newton's identities, also known as the Newton–Girard formulae, give relations between two types of symmetric polynomials, namely between power sums and elementary symmetric polynomials. Evaluated at the roots of a monic polynomial "P" in one variable, they allow expressing the sums of the "k"-th powers of all roots of "P" (counted with their multiplicity) in terms of the coefficients of "P", without actually finding those roots. These identities were found by Isaac Newton around 1666, apparently in ignorance of earlier work (1629) by Albert Girard. They have applications in many areas of mathematics, including Galois theory, invariant theory, group theory, combinatorics, as well as further applications outside mathematics, including general relativity.
Document 4: Horologium Oscillatorium: Horologium Oscillatorium: sive de motu pendulorum ad horologia aptato demonstrationes geometricae (Latin for "The Pendulum Clock: or geometrical demonstrations concerning the motion of pendula as applied to clocks"), often abbreviated Horologium Oscillatorium, is a book published by Christiaan Huygens in 1673; it is his major work on pendulums and horology. This work is regarded as one of the three most important work done in mechanics in the 17th century, the other two being Galileo Galilei’s "Discourses and Mathematical Demonstrations Relating to Two New Sciences" (1638) and Isaac Newton’s "Philosophiæ Naturalis Principia Mathematica" (1687).
Document 5: Suanfa tongzong: Suanfa tongzong (General Source of Computational Methods) is a mathematical text written by sixteenth century Chinese mathematician Cheng Dawei (1533–1606) and published in the year 1592. The book contains 595 problems divided into 17 chapters. The book is essentially general arithmetic for the abacus. The book was the main source available to scholars concerning mathematics as it developed in China’s tradition. Six years after the publication of Suanfa Tongzong, Cheng Dawei published another book titled "Suanfa Zuanyao" ("A Compendium of calculating Methods"). About 90% of the content of the new book came from the contents of four chapters of the first book with some rearrangement. It is said that when Suanfa Tongzong was first published, it sold so many copies that the cost of paper went up and the lucrative sales resulted in unscrupulous people beginning to print pirated copies of the book with many errors. it was this that forced the author to print an abridged version.
Document 6: Nicolas Fatio de Duillier: Nicolas Fatio de Duillier {'1': ", '2': ", '3': ", '4': "} (also spelled Faccio or Facio; 16 February 1664 – 12 May 1753) was a Swiss-born mathematician, natural philosopher, and inventor. He spent much of his adult life in England and Holland. Fatio is known for his work on the zodiacal light problem in astronomy, for originating the "push" or "shadow" theory of gravitation, for his close association with both Christiaan Huygens and Isaac Newton, and for his role in the Newton v. Leibniz calculus controversy. He also invented and developed the first method for fabricating jewel bearings for mechanical watches and clocks.
Document 7: Woolsthorpe-by-Colsterworth: Woolsthorpe (formally known as Woolsthorpe-by-Colsterworth to distinguish it from Woolsthorpe-by-Belvoir in the same county) is a hamlet in the South Kesteven district of Lincolnshire, England. It is best known as the birthplace of Sir Isaac Newton.
Document 8: Newton, Northamptonshire: Newton, sometimes called Newton in the Willows, is a small village in the Ise valley, Kettering, Northamptonshire. The village is in the civil parish of "Newton and Little Oakley" which had a population at the 2001 census of 147, decreasing to 126 at the 2011 Census. It has a combined parish council with Geddington.
Document 9: Woolsthorpe-by-Belvoir: Woolsthorpe, also known as Woolsthorpe-by-Belvoir, is a village and civil parish in the South Kesteven district of Lincolnshire, England. The population of the civil parish at the 2011 census was 415. It is situated approximately 5 mi west from Grantham, and adjoins the county border with Leicestershire. The neighbouring village of Belvoir lies on the other side of the border. Grantham Canal is situated 1 mi to the north-east at its closest point.
Document 10: Wold Newton, Lincolnshire: Wold Newton is a village and civil parish in North East Lincolnshire, England. The population of the civil parish at the 2011 census was 337. It is situated just over 1 mi west from the A18 road, 7 mi north-west from Louth, and 9.5 mi north-east from Market Rasen.
Document 11: Newton on the Moor: Newton on the Moor is a village in Northumberland, England. It is located 5 mi south of Alnwick, on the old route of the A1 road although the village has now been bypassed just to the east. The village in the civil parish of Newton on the Moor and Swarland, which also includes the village of Swarland, south-west of Newton on the Moor. The population of the parish is 822, increasing to 905 at the 2011 Census. The village is a conservation area.
Document 12: New Essays on Human Understanding: New Essays on Human Understanding (French: "Nouveaux essais sur l'entendement humain" ) is a chapter-by-chapter rebuttal by Gottfried Leibniz of John Locke's major work, "An Essay Concerning Human Understanding". It is one of only two full-length works by Leibniz (the other being the "Theodicy"). It was finished in 1704 but Locke's death was the cause alleged by Leibniz to withhold its publication. The book appeared some sixty years later. Like many philosophical works of the time, it is written in dialogue form.
Document 13: Method of Fluxions: Method of Fluxions is a book by Isaac Newton. The book was completed in 1671, and published in 1736. Fluxion is Newton's term for a derivative. He originally developed the method at Woolsthorpe Manor during the closing of Cambridge during the Great Plague of London from 1665 to 1667, but did not choose to make his findings known (similarly, his findings which eventually became the "Philosophiae Naturalis Principia Mathematica" were developed at this time and hidden from the world in Newton's notes for many years). Gottfried Leibniz developed his form of calculus independently around 1673, 7 years after Newton had developed the basis for differential calculus, as seen in surviving documents like “the method of fluxions and fluents..." from 1666. Leibniz however published his discovery of differential calculus in 1684, nine years before Newton formally published his fluxion notation form of calculus in part during 1693. The calculus notation in use today is mostly that of Leibniz, although Newton's dot notation for differentiation formula_1 for denoting derivatives with respect to time is still in current use throughout mechanics and circuit analysis.
Document 14: Woolsthorpe Manor: Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, near Grantham, Lincolnshire, England, is the birthplace and was the family home of Sir Isaac Newton. He was born there on 25 December 1642 (old calendar). At that time it was a yeoman's farmstead, principally rearing sheep.
Document 15: Disquisitiones Arithmeticae: The Disquisitiones Arithmeticae (Latin for "Arithmetical Investigations") is a textbook of number theory written in Latin by Carl Friedrich Gauss in 1798 when Gauss was 21 and first published in 1801 when he was 24. It is notable for having a revolutionary impact on the field of number theory as it not only turned the field truly rigorous and systematic but also paved the path for modern number theory. In this book, Gauss brought together and reconciled results in number theory obtained by mathematicians such as Fermat, Euler, Lagrange and Legendre and added many profound and original results of his own.
