Hardcover. Condition: New. 287 pages : facsimiles ; 25 cm. in Arabic. This book, "Treatise on the Angle" by Kamal al-Din al-Farisi belongs to the realm of mathematical educational science, representing one of the key specialist sciences in which scholars have demonstrated untrammeled creativity in making original contributions and inventing novel branches in this discipline that was unheard of in past civilisations. "A Treatise on the Angle" is one of a rare breed of books in our heritage, as it addresses a topic related to the discipline of mathematics history and philosophy, on the one hand, and on the other, is a study of the nature of the angle a philosophical mathematical concept from the perspective of Arab scholars. The importance of the topic stems from the necessity to study the essence of mathematical concepts so as to complete our knowledge of mathematics, and because it was not previously subject to detailed study in ancient Greek civilisation. This substantiates the keen interest that Arab and Muslim scholars had in the theoretical and intellectual aspects, alongside their interest in the applied aspects of the sciences, in their works, which were endowed with originality as a result.…

Hardcover. Condition: New. 657 pages : illustrations ; 25 cm. in Arabic. The work, Kitab al-tajrid fī usul al-handasah, is one of the key heritage sources for students of geometrical sciences, especially since the contributions of its author, Abū al-Hasan 'Ali b. Aḥmad al-Nasawi, have attracted special international recognition. The book lays the foundation for a practical geometry of Arab origin, covering discrete shapes (i.e. theories), which are independent from each other, leading to easy comprehension and assimilation. This geometry provides proofs in the domain of area and measurement, and establishes the roots of all principal human crafts. The work represents an important introduction leading to a more profound insight into the science of geometry, making it accessible to a wide range of people, while remaining simple enough for craftsmen. Al-Nasawī presented these forms using an approach defined by simplification, use of easy language, and comprehensible and robust proofs. The importance of the book, Kitab al-tajrid, is manifested in the methodology adopted by al-Nasawi in the presentation and flow of logically-connected scientific topics. Hence, he was able to construct a practical geometrical framework that served the aim for which the book was authored. In this work, al-Nasawi principally treated the topic of shapes composed of straight lines, and those theories related to the circle. He also covered the question of the circle, whether inscribed or circumscribed, in relation to regular shapes. In addition, he addressed the matter of proportion, applying the ratio theorem mainly to plane and three-dimentional Euclidean geometrical shapes, and others. …
