Summary Cubics in the math history The earliest found information about computing cubic roots and solution of cubic equations is found among the Babylonians (about 2000 - 400 BC). Hindu mathematicians took the Babylonian methods further so that Brahmagupta (598-665 AD) gives an, almost modern, method which admits negative quantities. Numerical values of cubic roots were computed by Aryabhata (476 -c. 550 BC) In about 300 BC Euclid developed a geometrical approach The solution of numerical higher equations for approximate values of roots has been known for a long time in China . It has been called the most characteristic Chinese mathematical contribution. The essentials of the method are there around c. 100 BC - 50 CE. By using the method for finding the cube root of a number they were able to solve a cubic equation of the form x + ax + bx = c , where a, b and c are positive. The Arabs did not know about the advances the Hindus had made so they had neither negative quantities nor abbreviations for their unknowns. However al'Khwarizmi (c 800) gave a classification of different types of equations.

Año: Páginas: 166 pp. ISBN: Comentario: Los ensayos monográficos redactados por plumas nacionales sobre aspectos de la alquimia en España no son desde luego habituales en nuestro país, de ahí que dar con este trabajo de Jesús Osácar Flaquer (antiguo miembro del Instituto de Carboquímica de Zaragoza, CSIC) me hiciera abordar su texto con gran atención. No en vano, en los últimos años toda una serie de investigadores foráneos han contribuido de forma importante a ahondar firmemente en la historia de la alquimia aragonesa. Contamos con las cuantiosas aportaciones de Michela Pereira sobre el beato Ramón Llull, las indagaciones de Julia Ortega en lo tocante a los alchimiayres al servicio de los reyes aragoneses, las publicaciones de Antoine Calvet y Giuliana Camili concernientes a los escritos pseudo-arnaldianos, las pesquisas de Pascale Barthélemy sobre los manuscritos de Guillem Sedacer, las transcripciones de la "Obraitge dels Philosophes" y de la "Somma" de Bernat Peire editadas por Suzanne Thiolier-Méjean... En la Edad Moderna española, desviándonos hacia el campo de la Iatroquínica, se escenifica desde finales del siglo XVI una tensión entre la medicina clásica y ciertas ideas renovadoras. Estas últimas, ejemplarmente expuestas en 1680 por Juan de Cabriada dentro de su "Carta filosófica médico-chymica" tienen como fundamento dos axiomas ya predicados por Paracelso un siglo y medio antes: cuestionar con dureza la autoridad de los clásicos y defender la experiencia como único criterio válido en

Astronomy in Sefarad Yuval Ne'eman Mortimer and Raymond Sackler Institute of Advanced Studies Tel Aviv University , Israel 1. Greeks and Hebrews: two intertwining intellectual progressions In very broad lines, Western culture is the outcome of two independent intellectual progressions: Greek philosophy and science, centered on a rational understanding of the world - and Hebrew ethics, worrying about the condition of man and his interaction with other men. On the Greek side, we note that at the beginning of the first Century AD, Eratosthenes (250 BC) had already computed the diameter of the earth with an error of less than 1/2 %, Hipparchus (150 BC) had evaluated the distance to the Moon with a 1/3 % precision, Hero (100 BC) had invented the steam engine [1]. On the Jewish side, Abraham (1800 BC) had put an end to human sacrifice, Moses (1300 BC) had codified the day of rest, to be applied even to slaves and house animals, Amos (800 BC) had preached social justice and Isaiah (700 BC) had already conceived the idea of universal peace - in a world where war remained the explicit ideal "manly" activity for another thousand years [2]. Note that in this ethical voyage of discovery, Jewish society had evolved "schools" as early as 1000 BC [3], the earliest foundations of what was later to become a learning-oriented culture. In parallel, we have, of course, the Athens Academy ( ~ 500 BC). With the destruction of the Second Temple (70 AD), the Jewish cult and rites centre on learning much more than before. Judaism, as remodeled for a countryless nation by Yokhanan Ben Zakkay (Ist Century AD) became a study-oriented religion. Note that 1000 years later, in medieval Europe, all male Jews were literate, at a time when in most of Europe, only churchmen could read.

69. 2nd_to_4th.nb The earliest record of the general quadratic solution is found in Liber Embadorum,written in 1145 CE by the Arab mathematician abraham bar hiyya HaNasi http://www.pitt.edu/~jagst135/polynomial/quartic/

* root formulae taken from Polynomials and Polynomial Inequalities , by Borwein and Erdelyi. Roots of the Quadratic Equation Source: Although methods of solving quadratics were well-known since the time of the Babylonians, these early mathematicians lacked the modern notation of equations in order to express such solutions in a general formula. Rather, they relied on (geometric-based) algorithms, which have been found equivalent to the method of "completing the square." The earliest record of the general quadratic solution is found in Liber Embadorum , written in 1145 C.E. by the Arab mathematician Abraham bar Hiyya Ha-Nasi (known as Savasorda). It differed from previous works, such as those of Al-Khwarizmi, which separated the problem into four cases, in order to avoid using negative quantities (a previous unknown). In the modern setting, the quadratic formula is familiar to us from grade school. For the equation: a + bx + c = , the solutions take the following form: x This follows from the method of completing the square. Roots of the Cubic Equation Source: The context of this discovery is a murky one. The earliest record of a solution is found in

72. The Ten Commandments We take this path as outlined by the Ten Commandments and as explained bya littleknown sage, Rabbi abraham bar hiyya of eleventh-century Spain. http://www.dfscott.com/bibal books/tencomm.asp

A Full Service Publisher - Quality Books at Reasonable Prices The Ten Commandments by Dennis S. Ross Two oval-topped tablets, standing side by side-everyone recognizes the religious symbol. But get to specifics-"You shall" and "You shall not"-it seems there is not much recognition at all. A recent public opinion survey discovered that most people cannot name more than a couple. And when the surveyors described the overlooked commandments, most participants were not happy with what they heard. Yet these "ten words" are the basis for Western ethics and law. Their influence permeates every niche of our society. In this book, Rabbi Ross presents the Ten Commandments as understood by Judaism, the religion of the people who gave them to the world. Indeed, the essence of the commandments is an outward reaching spirituality, not one that is self-absorbed. Judaism is a world engaging religion. The road to spiritual truth is not taken in isolation but is outward bound. We reach spiritual truth by engaging with the world, the family, and the community. The world is a good place, the human spirit is good, and worldly pleasures are to be enjoyed with moderation and within limits. Judaism teaches a unity of the spirit and the world. We take this path as outlined by the Ten Commandments and as explained by a little-known sage, Rabbi Abraham bar Hiyya of eleventh-century Spain. We learned that we cannot control our thoughts, but we can integrate our thinking and our doing. Speaking depends on nuance and is a way of engaging with family and community. We find a reasonable approach to honoring our parents and community, of caring for the weak and protecting strangers.

Recite II Travelling exhibition First inauguration 1 February 2000 " ... listening to time ..." (Catalogue of the exhibition) The European Bell Institute (IEAC Midi-Pyrenees) offered, for the year 2000, a new travelling exhibition dedicated to the history of time. The History of the calendar from 11000 B.C. to the present. The history of dividing time into years of 12 months, 52 weeks, 365 days, 8760 hours The history of telling time The history of clock-making from the medieval alarm clock to the quartz watch, by way of the history of monumental mechanical clocks, household clocks (comtoise clocks, pendulums), alarm watches, electric clocks and the atomic clock. The history of sound in time telling by means of religious or lay bells timbres, automatic carillons This exhibition was conceived in the framework of the European programme RECITE II. It is part of the IDC medici dossier on the construction of steeples. In this framework if helped develop an awareness by indigenous populations and regional European groups of the conservation of clock towers which have become real estate by allocation. First of all , these towers, symbols of identity of a community and a region, bells and monumental clocks give rhythm to the life of the local folk. Why, since when and how ? Here are some of the questions that the exhibition "... listening to time ..." offers to answer.
