The tremendous success of indivisibles methods in geometry in the seventeenth century, responds to a vast project: installation of infinity in mathematics. The pathways by the authors are very diverse, as are the characterizations of indivisibles, but there are significant factors of unity between the various doctrines of indivisible; the permanence of the language used by all authors is the strongest sign. These efforts do not lead to the stabilization of a mathematical theory (with principles or axioms, theorems respecting these first statements, followed by applications to a set of geometric situations), one must nevertheless admire the magnitude of the results obtained by these methods and highlights the rich relationships between them and integral calculus. The present book aims to be exhaustive since it analyzes the works of all major inventors of methods of indivisibles during the seventeenth century, from Kepler to Leibniz. It takes into account the rich existing literature usually devoted to a single author. This book results from the joint work of a team of specialists able to browse through this entire important episode in the history of mathematics and to comment it. The list of authors involved in indivisibles ́ field is probably sufficient to realize the richness of this attempt; one meets Kepler, Cavalieri, Galileo, Torricelli, Gregoire de Saint Vincent, Descartes, Roberval, Pascal, Tacquet, Lalouvère, Guldin, Barrow, Mengoli, Wallis, Leibniz, Newton.
This book narrates the extraordinary growth in the study of Arabic in England from the late sixteenth century, when it was almost non-existent, to the end of the seventeenth. By its high point around 1666, England was preeminent among European countries in the study of Arabic. Permanent chairs of Arabic had been established at Oxford and Cambridge, and specialized presses in Oxford and London had produced important Arabic works. In this masterly and original study, Professor Toomer gives the first detailed account of this process, set against the religious and political background in England and in Europe. He shows how trade with the Ottoman Empire and mistrust of Islam influenced the study of Arabic. Finally, he traces the course and causes of the drastic decline in Arabic studies towards the end of the century.
