It is known in English as The Meditation of the Sad Soul. This is the first edition of this sefer, and it comes with a very long introduction by Rav Shlomo Rapaport, the Rav of Prague in the middle 19th century, and with a biography of R' Avraham Bar Chiya, written by the publisher, Yitzchak Frieman. Or Hashem - àåø äùí R' Chasdai Crescas - ø' çñãàé ÷øù÷ù Ferrara, 1555 - ôéøøà, ùè"å Or Hashem is a major philosophical work written by one of the great Rishonim of the 14th century, from Spain, Rabeinu Chasdai Crescas who was the student of the Ran, and the rebbe of the Rivash and Rabeinu Yosef Albo, the author of Sefer HaIkkarim. In Or Hashem, R' Chasdai Crescas rejects all kinds of Greek philosophy and many ideas of the Rambam and the Ralbag. He redefines the Principles of Faith, of which there are 6 and not 13 as the Rambam wrote. Or Hashem parallels the Rambam's Moreh Nevuchim and the Ralbag's MIlchamos Hashem. This is the first edition of this sefer published in Ferrara, Italy in 1555. Sefer HaTapuach - ñôø äúôåç

3. History Of Mathematics - Al'Khwarizmi & Al Jabr In 1145, savasorda published Liber embadorum that gave the complete solution of the quadratic equations http://members.aol.com/bbyars1/algebra.html

Many say that the Babylonians first developed systems of quadratic equations. This calls for over simplification, because the Babylonians had no concept of an equation. Also, all solutions to Babylonian problems were positive because they were solutions to problems involving lengths. Six Types of Quadratics 3. Roots equal to numbers (square root of x = 2) (6 + square root of 10)(18 - square root of 90) = (108 - square root of 3240 + square root of 3240 - square root of 900) which is 78 Scipione dal Ferro is the first credited with solving cubic equations algebraically, around 1515. However, he could only solve cubic equations with the form He kept this work a secret until 1526 when he revealed it to his student Antonio Fior. Soon, the work was common knowledge around Bologna, where dal Ferro taught at the University of Bologna. Other observations in the field of complex equations were also made, primarily that of Harriot. He observed that if x = b, x = c, x = d then (x - b)(x - c)(x - d) = which allowed more uses for the cubic equations. Many proofs after this followed, including ones which first proved these principles algebraically, instead of geometrically. The further use of algebra supplemented modern mathematics in a very important way.

7. INSCRIPT referring to a geometry book by Abraham bar Hiyya savasorda in library of San Marco, Florence; bottom left corner http://is.gseis.ucla.edu/impact/f95/Cdwa/INSCRIPT.HTML

Inscriptions/Marks DEFINITION A description of distinguishing or identifying physical markings, lettering, annotations, texts, or labels that are a part of a work of art or are affixed, applied, stamped, written, inscribed, or attached to the work, excluding any mark or text inherent in materials. SUBCATEGORIES TRANSCRIPTION OR DESCRIPTION TYPE AUTHOR LOCATION TYPEFACE/ LETTERFORM DATE REMARKS CITATIONS DISCUSSION A precise transcription or a prose description of the inscription is important to provide clarity and explain unusual features of the inscription. The information in this transcription should then be indexed in other subcategories; this makes it possible to formulate queries about types of inscriptions and their authors, as well as their locations, dates, and scripts. When an inscription or mark is documented, the following characteristics are important: who made it, the way it was made (materials and technique), its location on the object, and an indication of what the inscription says or what the mark looks like. This may include a transcription, transliteration (if it is not in the Roman alphabet), description, or translation. Remarks about the significance of an inscription or mark, and citations to any sources used to identify or describe an inscription or mark, can also be recorded. Inscriptions and marks are important aids in authenticating a work or object. They also assist in interpretation and dating, and provide information about a work's history. This category is also used to record works that are primarily textual.

Abraham bar Hiyya Ha-Nasi Born: 1070 in Barcelona, Spain Died: 1136 in Provence, France Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Abraham bar Hiyya was a Spanish Jewish mathematician and astronomer. In the Hebrew of his time 'Ha-Nasi' meant 'the leader' 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

11. Earliest Uses Of Symbols From Geometry in the middle of the twelfth century in Plato of Tivoli's translation of the Liber embadorum by savasorda (Cajori vol http://members.aol.com/jeff570/geometry.html

Earliest Uses of Symbols from Geometry Last revision: August 26, 2001 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 (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).
