1201 to 1300 Setting the scene The influence of Islamic civilisation is still the major factor in the development of scientific thought. However European thinkers and intellectuals are beginning to have some influence again. The science The Chinese devise a sign for zero. In 1202 it is introduced to Europe for the first time, where it begins to change the way people do maths. Jordanus Nemorarius writes the book Mechanica which contains a law about the way levers work and a law on the composition of movements. The earliest known description of a wheelbarrow appears as a stained glass window in Chartres Cathedral in France. The alchemist Arnold of Villanova ALMOST discovers carbon monoxide and is the first known person to prepare pure alcohol. The Chinese use bombs to produce shrapnel and damage - until then explosives had only been used to produce fire, light, noise and confusion among the enemy. They also use kites as a way of sending signals behind the enemy lines. In 1270 Witelo publishes his Perspectiva , a book on optics which deals with refraction, reflection and geometrical optics. Perhaps most importantly, Witelo rejects the current idea that rays of light are emitted from the eye.

Next: About this document Mideval Europe century The Europeans learned Arabic in the 12 century. All mathematics and astronomy was written in Arabic. By the end of the 12 century the best mathematics was done in Christian Italy. During this century there was a spate of translations of Arabic works to Latin. Later Example. Elements in Arabic Latin in 1142 by Adelard of Bath (ca. 1075-1160). He also translated Al-Khwarizmi's astronomical tables (Arabic Latin) in 1126 and in 1155 translated Ptolemy's Almgest (Greek Latin) (The world background at this time was the crusades.) Gherard of Cremona Born: 1114 in Cremona, Italy Died: 1187 in Toledo, Spain Gherard's name is sometimes written as Gerard. He went to Toledo, Spain to learn Arabic so he could read Ptolemy's Almagest since no Latin translations existed at that time. He remained there for the rest of his life. Gherard made translations of Ptolemy (1175) and of Euclid from Arabic. Some of these translations from Arabic became more popular than the (often earlier) translations from Greek. In making translations of other Arabic work he translated the Arabic word for sine into the Latin sinus, from where our

Renn (Department I) Historical epistemology in this sense requires an integration of cultural and cognitive studies of science. Methods and results of the cognitive sciences, of the structuralist tradition of psychology as well as of philosophical theories of concept development, can help to compensate for theoretical deficits in the history of science in a narrow sense, in particular when it comes to explaining thought processes. The history of science can, inversely, contribute to overcoming the limitations of theoretical approaches whose claims have not yet been systematically confronted with the results of historical research. However, such an historical epistemology would not only have to add the models and scientific means of the social and cognitive sciences to the traditional methodological arsenal of the history of science, but must also develop a theoretical coherency that goes beyond exploiting historical case studies to flesh out preconceived philosophical opinions. In order to achieve a broad historical basis for dealing with these theoretical problems and to cover at least some of the major developmental steps in the history of science, research has been inaugurated or is planned in four different areas: the emergence of formal sciences such as mathematics; the emergence of empirical sciences such as physics, chemistry, and biology; structural changes in sciences with developed disciplinary structures and integrated theoretical foundations, such as the transition from classical to modern physics; and the role of reflective thinking and second-order concepts in science.

Series One focuses on the great library of John Dee (1527-1608), philosopher, mathematician, astrologer and theologian. Under the guidance and general editorship of Dr Julian Roberts and Dr Elisabeth Leedham-Green this project aims to reconstruct Dee's Library based on the findings published in John Dee's Library Catalogue , edited by Julian Roberts and Andrew G Watson, (The London Bibliographical Society, 1990). Parts 1 and 2 focus on manuscript materials from the Bodleian Library, Oxford, and Corpus Christ College, Oxford. Parts 3-6 concentrate mainly on Dee's printed books. Part 3 is based on the holdings of Cambridge University Library and Parts 4-6 bring together the largest surviving group of Dee's printed books from the holdings of the Dorchester Library at the Royal College of Physicians, London.

This more clear in the second half than of the first, since all the scientific leaders were Muslims, or at any rate were working with and for Muslims and wrote in Arabic. Cultural Background Abbasid Caliph Al-Mutawakkil (847-861) continued to protect men of science, chiefly the physicians, and he encouraged the school of translators headed by Hunain ibn Ishaq. Da ud al-Zahiri founded a new school of theology, based upon a more literal interpretation of the Qur'an; however, did not survive very long. Muslim published a new collection of traditions, arranged according to legal topics, like Bukhari's, but more theoretical. The Egyptian Dhul-Nun is generally considered the founder of Sufism, that is, of Muslim mysticism.

Charles Sanders Peirce The Collected Papers: Principles of Philosophy II. The Classification of the Sciences 2. A Detailed Classification of the Sciences §6. The Divisions of Mathematics 283. Having now attained to a pretty clear apprehension of what a natural order of science is — deficient in distinctness though this apprehension be — we cannot, if we have any acquaintance with mathematics, consider that class of science, without seeing that none more manifestly falls into orders than this. The hypotheses of mathematics relate to systems which are either finite collections, infinite collections, or true continua; and the modes of reasoning about these three are quite distinct. These, then, constitute three orders. The last and highest kind of mathematics, consisting of topical geometry, has hitherto made very little progress; and the methods of demonstration in this order are, as yet, little understood. The study of finite collections divides into two suborders: first, that simplest kind of mathematics which is chiefly used in its application to logic, from which I find it almost impossible to separate it ; and secondly, the general theory of finite groups. The study of infinite collections likewise divides into two suborders; first, arithmetic, or the study of the least multitudinous of infinite collections; and second, the calculus, or the study of collections of higher multitude. Hitherto, the calculus has been entirely confined to the study of collections of the lowest multitude above that of the collection of all integral numbers. This is studied either algebraically or geometrically, or, much more commonly, and perhaps more advantageously (though it is out of fashion to think so), by the two methods combined. The traditional division of mathematics, still much used, is into geometry and algebra — the division used by Jordanus Nemorarius
