Extractions: * root formulae taken from Polynomials and Polynomial Inequalities , by Borwein and Erdelyi. 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).

Extractions: Staff FROM THE RABBI Rabbi Hiyya bar Abba fell ill and Rabbi Yohanan went in to visit him. Rabbi Yohanan said to him, Does your suffering have meaning to you? Rabbi Hiyya bar Abba replied, Neither they nor their reward. Rabbi Yohanan said to him, Give me your hand. Rabbi Hiyya bar Abba stretched out his hand and Rabbi Yohanan raised him up. (Babylonian Talmud, Berachot 5b) This short anecdote from the Talmud clearly illustrates the mitzvah of bikur cholimvisiting the sick. We are taught in Genesis that God visited Abraham while he recovered from his circumcision at age 90! In Numbers, after Miriam is afflicted with tzaraat (a white scaly skin affliction), Moses prays for her with the simple words, El na refah na laplease God, please heal her. Jews have long understood the need to visit the sick, which responds to two of the greatest burdens of contemporary life: isolation and lack of community. At a time of illness, bikur cholim offers us the comfort of human connection and interdependence, a sense of community we so desperately need. Our congregation has long had a Bikur Cholim Committee. Four years ago, with the help of Marjorie Sokol of Jewish Family and Childrens Services, I led a workshop to train volunteers to visit the sick and to understand the role of healing in the Jewish tradition. Under the wonderful and caring guidance of Bikur Cholims co-chairsNancy Hodin, Eileen Sussman, and Marilyn Zievethis committee now has close to 30 trained volunteers who are ready, willing, and able to make visits and phone calls to those who are ill, lonely, and in need of healing. Like Rabbi Yohanan in the Talmudic tale, these volunteers know that their role is not necessarily to heal, but to lift the spirit of another.

Extractions: A Full Service Publisher - Quality Books at Reasonable Prices 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.

Extractions: Abraham's Discovery And God said to Abram: 'Go out from your country, from your birthplace, from the home of your father, to the land which I will show you ...' [Genesis 12:1] This Torah portion begins with the Divine directive to Abram (later to be known as Abraham) to leave his home for a destination unknown. Who was this man Abram and why was he chosen for this special directive? How had he merited God's attention? Why was he, of all people, destined to become the first of the patriarchs, the father of many nations? Regarding all these questions, the Torah is silent. Of course, the Midrashic literature ably fills in all the gaps, recounting Abram's many trials and tribulations as a child and young man. We are told of his lonely spiritual quest and eventual discovery of the One God. While we have no question about the authenticity of the Oral Tradition, why does the Torah itself not share these details with us? Of course, such a question could be posed about any section of Midrash, but, in this instance the complete lack of explanation of Abram's special status in the Torah leaves us especially puzzled. After all, Abram was selected for a truly monumental encounter with God an encounter which would give humanity monotheism and change the world forever. Why is the reason for something so important related exclusively through the Oral Tradition?

Extractions: by Kenneth L. Cohen Rabbi Hiyya said, "I have never concentrated on prayer all of my days. Once I tried to concentrate, but all I could think about was politics." Shmuel said, "During prayer, I count the clouds." Rabbi Bun Bar Hiyya said, "I count the stones in the wall when I should be praying." Rabbi Matnaya said, "I am grateful to my head, because it knows to bow automatically when we reach the Modim prayer." The tension between keva (fixed prayer) and kavanah (proper intention) is an age-old one. How does one prevent prayer from become a rote, and therefore unfulfilling, experience? I discovered one tactic in my quest for kavanah. Periodically, I would change prayerbooks. The different pagination, different typeface, different commentaries would keep prayer fresh. For the most part, this worked.

Extractions: Larry Sitsky was born in Tianjin (Tientsin), China, to Russian Jewish parents. He began learning the piano and composition at an early age. Sitsky immigrated to Australia in 1951, by which time the mystical influences of Jewish, Russian and East Asian cultures had made a strong impression on his style. [When considering the Aramaic text] the indications of a later date are not so obvious, but linguistic analysis and a comparison of language of the Zohar with known Aramaic sources show that this Aramaic is an artificial language drawn from specific literary source material, and it contains a mixture of dialectical linguistic expressions that never existed side by side in the living language. It [The Zohar] contains words and idioms that originated in medieval [sic] Hebrew and they can be seen through the Aramaic veneer. The poverty of the vocabulary [attested to by Gershom G. Scholem], which contains no more than a few thousand words, and the many errors in word formation and syntax, also show that we are dealing with a late artificial language.

Archimedes of Syracuse (287 BC to 212 BC) Archimedes to Eratosthenes greeting. ... certain things first became clear to me by a mechanical method, although they had to be demonstrated by geometry afterwards because their investigation by the said method did not furnish an actual demonstration. But it is of course easier, when we have previously acquired by the method, some knowledge of the questions, to supply the proof than it is to find it without any previous knowledge. Introduction to Arithmetic Proclus Diadochus (411 to 485) According to most accounts, geometry was first discovered among the Egyptians, taking its origin from the measurement of areas. For they found it necessary by reason of the flooding of the Nile, which wiped out everybody's proper boundaries. Nor is there anything surprising in that the discovery both of this and of the other sciences should have had its origin in a practical need, since everything which is in process of becoming progresses from the imperfect to the perfect. On Euclid The Pythagoreans considered all mathematical science to be divided into four parts: one half they marked off as concerned with quantity, the other half with magnitude; and each of these they posited as twofold. A quantity can be considered in regard to its character by itself or in relation to another quantity, magnitudes as either stationary or in motion. Arithmetic, then, studies quantity as such, music the relations between quantities, geometry magnitude at rest, spherics magnitude inherently moving.

(...) Con ello y, como consecuencia, aparece emparejado el tema,de procedencia semita, árabe y judía, cual es el de las relaciones entre fe y filosofía, o razón, entre religión y fe, entre pensamiento humano y revelación. Para Averroes y Maimónides, la filosofía y la religión no se pueden contradecir a pesar de que son autónomas, porque apuntan y llevan a la misma Verdad» La Sefarad bíblica Pese a su poética resonancia oriental, la palabra hebrea «Sefarad» no se refiere a Asia: designa a la Península Ibérica, y «sefaradí» quiere decir judío oriundo de España o Portugal.

Extractions: Desde os tempos mais remotos os textos de matemática incluem problemas para os leitores resolverem. Os textos mais antigos como os Egípcios , os Babilónios e os Chineses eram compostos por uma lista de problemas cujas soluções eram depois fornecidas. Por exemplo, o mais antigo destes textos, de origem egípcia, conhecido por Papiro de Rhind contém uma colecção de 85 problemas. Os problemas eram escolhidos como uma forma de ensinar, ao leitor, a matemática, sendo muitas vezes colocados por grau de dificuldades; por outro lado estes problemas reflectem, muitas vezes, as necessidades das sociedades, os diferentes aspectos da vida quotidiana, etc. Livros com problemas matemáticos apareceram em todas as civilizações, ao longo da história até aos nossos dias. Espantosamente, o mesmo problema aparece em textos de civilizações diferentes e em diferentes períodos da história.
