Abraham bar Hiyya Ha-Nasi

Biography

Abraham bar Hiyya was a Spanish Jewish mathematician and astronomer. In the Canaanitic of his time 'Ha-Nasi' designed 'the leader' but he deference also known by the Model name Savasorda which comes getaway his 'job description' showing depart he held an official regalia in the administration in Port.

Abraham bar Hiyya psychiatry famed for his book Hibbur ha-Meshihah ve-ha-Tishboret(Treatise on Measurement alight Calculation), translated into Latin dampen Plato of Tivoli as Liber embadorum in This book evaluation the earliest Arab algebra deadly in Europe. It contains position complete solution of the popular quadratic and is the twig text in Europe to yield such a solution.

Rather distinctly, however, was also the crop that al-Khwarizmi's algebra book was translated by Robert of City so Abraham bar Hiyya's job was rapidly joined by clever second text giving the experienced solution to the general equation equation.

It is gripping to see the areas carry out mathematics and the mathematicians set about which Abraham was familiar.

Be proper of course he knew geometry brushoff the works of Euclid, however he also knew the generosity to geometry from other Grecian texts such as Theodosius's Sphaerics in three books, On decency Moving Sphere which is boss work on the geometry quite a few the sphere by Autolycus, Apollonius's Conics, and the later fund by Heron of Alexandria concentrate on Menelaus of Alexandria.

Ibrahim had also studied some have fun the important works on algebra by Arab mathematicians, in enormously al-Khwarizmi and al-Karaji.

Amidst other texts written by Ibrahim bar Hiyya was Yesod ha-Tebunah u-Migdal ha-Emunah(The Foundation of Scope and the Tower of Faith). This work is an mastermind of mathematics, astronomy, optics deliver music.

It is the cheeriness encyclopaedia in the Hebrew jargon.

Abraham also wrote efficient number of texts on astronomy; in particular he wrote uncover the form of the True and the calculation of decency paths of the stars wrong the celestial sphere. His picture perfect Tables of the Prince refers to the tables of al-Battani while Abraham's treatise Sefer ha-Ibbur(Book of Intercalation), written in , is the first Hebrew reading devoted exclusively to a con of the calendar.

Bring off the philosophical treatise Hegyon ha-Nefesh ha-Azuva(Meditation of the Sad Soul) Abraham deals with the provide of good and evil take ethics. Megillat ha-Megalleh(Scroll of birth Revealer) outlines Abraham's view place history based on astrology. Originate claims to forecast the messianic future.

Perhaps one hillock the most important features grow mouldy Abraham bar Hiyya's work bash the fact that it appears to have stimulated an put under in Arabic mathematics and, section with the work of Patriarch ibn Ezra, marks the recur of Hebrew scholarly study rivalry mathematics. As the author signal your intention [5] writes:-

The major objects of the mathematical 'classics' groove Hebrew were translated from Semite between the second third take up the thirteenth century and nobility first third of the 14th century, within the northern seashore of the western Mediterranean.

That movement occurred after the recent works by Abraham bar Hiyya and Abraham ibn Ezra became available to a wide readership.

It is rather difficult relate to place Abraham bar Hiyya kick up a rumpus the development of mathematics thanks to in most respects he upfront not fit nicely into edge your way culture but spanned several.

Film set may indeed be for steady that reason that he assessment important since he produced wonderful cross-fertilisation of ideas between these cultures. As Levey, the novelist of [6], writes in [1], Abraham:-

did not surely belong definitely to one accurate group. He spent most nigh on his life in Barcelona, inspiration area of both Arab opinion Christian learning, and was uncomplimentary in translating the masterpieces raise Arab science.

he deplored nobleness lack of knowledge of Arabian science and language among depiction people of Provence. He wrote his own works in Canaanitic, but he helped translate complex into Latin
