27. Quadratic Formula Abraham bar Hiyya HaNasi (also known by the Latin name savasorda) was the firstto introduce the complete solution to Europe in his book Liber embadorum. http://www.fact-index.com/q/qu/quadratic_formula.html

Main Page See live article Alphabetical index Quadratic formula The quadratic formula explicitly gives the solutions x to the quadratic equation in terms of the coefficients a b and c , which we temporarialy assume to be real (but see below for generalizations) with a being non-zero. These solutions are also called the roots of the equation. The formula reads The term b ac is called the discriminant of the quadratic equation, because it discriminates between three qualitatively different cases: If the discriminant is zero then there is a repeated solution x , and this solution is real. Geometrically, this means that the parabola described by the quadratic equation touches the x -axis in a single point. If the discriminant is positive, then there are two different solutions x , both of which are real. Geometrically, this means that the parabola intersects the x -axis in two points. Furthermore, if the discriminant is a perfect square, the roots are rational numbers in other cases they may be quadratic irrationals. If the discriminant is negative, then there are two different solutions

28. Toledo And All That to the Barcelona of around 1145, we find another Italian, Plato Tiburnensis (of Tivoli),translating with the help of the Jewish interpreter Abraham savasorda http://www.fut.es/~apym/on-line/studies/toledo.html

Negotiating the Frontier (unpublished work in progress) Toledo and All That [An earlier version of this chapter was published as "Twelfth-Century Toledo and Strategies of the Literalist Trojan horse", Target 6/1 (1994), 43-66.] In asking this question, I am not really interested in whether there was a 'School of Toledo' in any capital-letter sense of the term, which is a matter for historians of glory. My concern is more literal and lower-case: What relation could there have been between translation and a little actual schooling, in the sense of teaching and learning things Arabic? My working hypothesis is that any translating associated with pedagogical activities must have been in some way related to the church. The principles of the translating might thus be sought in this relation. Further, if there was tension in the relation, the principles might be formulated in terms of a negotiation, hopefully in the form of a much better negotiation than anything the abbot of Cluny was able to achieve. What's in a School?

ATTEMPT AT A CHRONOLOGY OF HISPANIC TRANSLATION HISTORY TWELFTH CENTURY 1106 Petrus Alfunsis (Alfonsi), in Huesca, is converted from Judaism to Christianity at the age of 44. 1108 Petrus Alphunsis writes Dialogi contra Judaeos. 1108 Beginnings of the Pisan quarter in Antioch. 1110 Petrus Alphunsis visits England, where he is probably physician to Henri I Beauclerc. 1112 Petrus Chrysolanus (archbishop of Milan), in Constantinople, disputes before Emperor Alexis. 1114 Johannes Afflacius ('the Saracen') and Rusticus (physician), in Pisa, translate Ali ben Abbas's De chirurgia. 1114-15 'iohannes quidam agarenus (Saracenus?) quondam' translates part of Ali ibn Abbas's Practica. c.1115 Adelardus de Bada (of Bath) writes Liber ysagogarum Alchorismi. 1116 Petrus Alphunsis writes Sentencia de dracone. 1118 Christians take Zaragoza. 1119 The university of Bologna is founded. 1119-51 Michael (probably French) is bishop of Tarazona, which has just been taken from the Arabs. He seeks Arabic texts on astrology and divination and sponsors their translation into Latin by Hugo Sanctillanus. 1120 Walcher, prior of Malvern, translates into Latin a work on astronomy by Petrus Alphunsis.

Abraham bar Hiyya Ha-Nasi Born: 1070 in Barcelona, Spain Died: 1136 in Provence, France Abraham bar Hiyya was a Spanish Jewish mathematician and astronomer. His name is Hebrew for 'the prince' but he is also known by the Latin name Savasorda which comes from his 'job description' showing that he held an official position in the administration in Barcelona. Abraham bar Hiyya is famed for his book Hibbur ha-Meshihah ve-ha-Tishboret (Treatise on Measurement and Calculation), translated into Latin by Plato of Tivoli as Liber embadorum in 1145. This book is the earliest Arab algebra written in Europe. It contains the complete solution of the general quadratic and is the first text in Europe to give such a solution. Rather strangely, however, 1145 was also the year that al-Khwarizmi 's algebra book was translated by Robert of Chester so Abraham bar Hiyya's work was rapidly joined by a second text giving the complete solution to the general quadratic equation. It is interesting to see the areas of mathematics and the mathematicians with which Abraham was familiar. Of course he knew geometry through the works of Euclid , but he also knew the contributions to geometry from other Greek texts such as Theodosius 's Sphaerics in three books

The COMBINATORIAL ASTROLOGY of Rabbi ABRAHAM IBN EZRA (1089-1164) by Doron ZEILBERGER Department of Mathematics, Temple University, Philadelphia, PA 19122, USA. http://www.math.temple.edu/ Ibn Ezra was born in Tudela, Spain. At that time, all of the great mathematicians were 'Spanish'. Indeed, in the 11th and 12th centuries, the greatest contribution to science was made by the Jewish scholars, especially in Spain. Names known from religious sources as 'Rabbis' and 'Kabbalists' are known in history books of mathematics and science as outstanding inventors and developers. Rabbi Abraham bar-Chiya (known in science books as Savasorda) of Barcelona, wrote and published in Hebrew the encyclopedia entitled Source of Intelligence and Tower of Belief and the book entitled Liber Embadorum treating about geometry and arithmetic theories. His books were translated into Latin and German and used as a source for other mathematicians- Ibn Ezra published his famous mathematic books in Hebrew: Book of Unity Book of Number , and Stratagem . In his books he refers to two Jewish researchers who published books in the 10th century: A judge named Hazan from an unknown source and a physicist named Yehuda ben-Rakufial. We're talking about one of the all-time greatest thinkers in the following categories of intellectual endeavor: Poet : e.g.:

34. The Quadratic - Page Two Abraham bar Hiyya HaNasi, often known by the Latin name savasorda, is famed forhis book Liber embadorum published in 1145 which is the first book published http://www.vimagic.de/hope/2/quadratic_two.html

L ater, Brahmagupta (598-665 AD) gives an, almost modern, method which admits negative quantities. He also used abbreviations for the unknown, usually the initial letter of a colour was used, and sometimes several different unknowns occur in a single problem. T he Arabs did not know about the advances of the Hindus so they had neither negative quantities nor abbreviations for their unknowns. However al-Khwarizmi (c 800) gave a classification of different types of quadratics (although only numerical examples of each). The different types arise since al-Khwarizmi had no zero or negatives. He has six chapters each devoted to a different type of equation, the equations being made up of three types of quantities namely: roots, squares of roots and numbers i.e. x, x and numbers. A l-Khwarizmi solves each type of equation: Squares equal to roots Squares equal to numbers Roots equal to numbers Squares and roots equal to numbers Squares and numbers equal to roots Roots and numbers equal to squares - essentially the familiar quadratic formula given for a numerical example in each case, and then a proof for each example which is a geometrical completing the square. A braham bar Hiyya Ha-Nasi , often known by the Latin name Savasorda , is famed for his book Liber embadorum published in 1145 which is the first book published in Europe to give the complete solution of the quadratic equation.

Abraham Bar Hiyya Ha- Nasi PAGE THREE Abraham bar Hiyya Ha-Nasi, often known by the Latin name Savasorda, is famed for his book Liber Embadorum published in 1145 which is the first book published in Europe to give the complete solution of the quadratic equation. A new phase of mathematics began in Italy around 1500. In 1494 the first edition of Summa de arithmetica, geometrica, proportioni et proportionalita, now known as the Suma, appeared. It was written by Luca Pacioli although it is quite hard to find the author's name on the book, Fra Luca appearing in small print but not on the title page. In many ways the book is more a summary of knowledge at the time and makes no major advances. The notation and setting out of calculations is almost modern in style: 6.p.R.10 18.m.R.90 Home page

38. Earliest Uses Of Symbols From Geometry Arc. The arc symbol appears in the middle of the twelfth century in Plato ofTivoli s translation of the Liber embadorum by savasorda (Cajori vol. http://mail.mcjh.kl.edu.tw/~chenkwn/mathword/geometry.html

Earliest Uses of Symbols from Geometry Last revision: July 4, 1999 Lettering of geometric figures. The designation of points, lines, and planes by a letter or letters was in vogue among the ancient Greeks and has been traced back to Hippocrates of Chios (about 440 B. C.) (Cajori vol. 1, page 420, attributed to Moritz Cantor). Lettering of triangles. Richard Rawlinson in a pamphlet prepared at Oxford sometime between 1655 and 1668 used A, B, C for the sides of a triangle and a, b, c for the opposite angles. In his notation, A was the largest side and C the smallest (Cajori vol. 2, page 162). Leonhard Euler and Thomas Simpson reintroduced this scheme many years later, Euler using it in 1753 in Histoire de l'acad?mie de Berlin (Cajori vol 2., page 162). Euler used capital letters for the angles. In 1866, Karl Theodor Reye (1838-1919) proposed the plan of using capital letters for points, lower case letters for lines, and lower case Greek letters for planes in a remarkable two-volume work on geometry, Die Geometrie der Lage (Cajori vol. 1, page 423).

¦­´Á¼Æ¾Ç¦r·Jªº¾ú¥v (A) Last revision: July 29, 1999 ABELIAN EQUATION. Leopold Kronecker (1823-1891) introduced the term Abelsche Gleichung in an 1853 paper on algebraically soluble equations. He used the term to describe an equation which in modern terms would be described as having cyclic Galois group [Peter M. Neumann]. ABELIAN FUNCTION. C. G. J. Jacobi (1804-1851) proposed the term Abelsche Transcendenten (Abelian transcendental functions) in Crelle's Journal 8 (1832) (DSB). Abelian function appears in the title "Zur Theorie der Abelschen Functionen" by Karl Weierstrass (1815-1897) in Crelle's Journal, Weierstrass' first publications on Abelian functions appeared in the Braunsberg school prospectus (1848-1849). ABELIAN GROUP. Camille Jordan (1838-1922) wrote groupe ab?lien in 1870 in Trait? des Substitutions et des Equations Alg?braiques. However, Jordan does not mean a commutative group as we do now, but instead means the symplectic group over a finite field (that is to say, the group of those linear transformations of a vector space that preserve a non-singular alternating bilinear form). In fact, Jordan uses both the terms "groupe ab?lien" and "?quation ab?lienne." The former means the symplectic group; the latter is a natural modification of Kronecker's terminology and means an equation of which (in modern terms) the Galois group is commutative. An early use of "Abelian" to refer to commutative groups is H. Weber, "Beweis des Satzes, dass jede eigentlich primitive quadratische Form unendlich viele Primzahlen darzustellen f?hig ist,"
