This volume highlights the scientific advances and ruptures of classical Islam with respect to Hellenism, and the emergence of a new mathematical rationality and a new relationship between mathematics and physics, from a comparative synchronic and diachronic perspective.

The Studies in the History and Culture of the Islamic Orient (STIO) is the series of “Supplements” to the journal Der Islam. Both are published by the Section for the History and Culture of the Near East in the Asian-African Institute of the University of Hamburg. The Section was established in 1908, before the foundation of the University of Hamburg. Under its first Director, C.H. Becker, it was the first academic centre in Germany in which teaching and research concentrated on the historical and cultural aspects of the Islamic world, and not just on philological issues. Many of Germany’s leading authorities in Islamic Studies have studied and/or taught here. The “Supplements” have maintained the same high quality and met the same high demands as the journal Der Islam and have published numerous studies on the history and culture of the Islamic world which have represented milestones in their relevant fields. The “New Series” of Supplements appearing since 2004 carries this tradition forward and provides a platform for publishing studies on the history and culture of the Islamic world from the beginnings of Islam up to the present day.

First published in 1202, Fibonacci’s Liber Abaci was one of the most important books on mathematics in the Middle Ages, introducing Arabic numerals and methods throughout Europe. This is the first translation into a modern European language, of interest not only to historians of science but also to all mathematicians and mathematics teachers interested in the origins of their methods.

Knowledge and Education in Classical Islam: Religious Learning between Continuity and Change is a pioneering collection of essays on the historical developments, ideals, and practices of Islamic learning and teaching in the formative and classical periods of Islam (i.e., from the seventh to fifteenth centuries CE). Based on innovative and philologically sound primary source research, and utilizing the most recent methodological tools, this two volume set sheds new light on the challenges and opportunities that arise from a deep engagement with classical Islamic concepts of knowledge, its production and acquisition, and, of course, learning. Learning is especially important because of its relevance to contemporary communities and societies in our increasingly multicultural, “global” civilizations, whether Eastern or Western.

Prime Obsession taught us not to be afraid to put the math in a math book. Unknown Quantity heeds the lesson well. So grab your graphing calculators, slip out the slide rules, and buckle up! John Derbyshire is introducing us to algebra through the ages-and it promises to be just what his die-hard fans have been waiting for. "Here is the story of algebra." With this deceptively simple introduction, we begin our journey. Flanked by formulae, shadowed by roots and radicals, escorted by an expert who navigates unerringly on our behalf, we are guaranteed safe passage through even the most treacherous mathematical terrain. Our first encounter with algebraic arithmetic takes us back 38 centuries to the time of Abraham and Isaac, Jacob and Joseph, Ur and Haran, Sodom and Gomorrah. Moving deftly from Abel's proof to the higher levels of abstraction developed by Galois, we are eventually introduced to what algebraists have been focusing on during the last century. As we travel through the ages, it becomes apparent that the invention of algebra was more than the start of a specific discipline of mathematics-it was also the birth of a new way of thinking that clarified both basic numeric concepts as well as our perception of the world around us. Algebraists broke new ground when they discarded the simple search for solutions to equations and concentrated instead on abstract groups. This dramatic shift in thinking revolutionized mathematics. Written for those among us who are unencumbered by a fear of formulae, Unknown Quantity delivers on its promise to present a history of algebra. Astonishing in its bold presentation of the math and graced with narrative authority, our journey through the world of algebra is at once intellectually satisfying and pleasantly challenging.

The American Journal of Islamic Social Sciences (AJISS), established in 1984, is a quarterly, double blind peer-reviewed and interdisciplinary journal, published by the International Institute of Islamic Thought (IIIT), and distributed worldwide. The journal showcases a wide variety of scholarly research on all facets of Islam and the Muslim world including subjects such as anthropology, history, philosophy and metaphysics, politics, psychology, religious law, and traditional Islam.
