Armillary spheres can be divided into two main categories: the observational armillary, as used by Ptolemy and Tycho Brahe; and the demonstrational instrument. Both types consist of a number of rings (Latin: armillae) which are arranged so as to model the circles of the celestial sphere. Typically, armillary spheres used for observation were larger and possessed fewer rings than those which served as demonstrational instruments; this made them more accurate and easier to use. Often the rings of demonstrational armillaries, like those of the observational spheres, were divided, and some incorporated sights which could be used to orient the instrument appropriately.

In this section we should again mention the names of Mark Antun Dominis and Rugjer Boskovic, whose work was veritably encyclopaedistic.
The first known manual about book-keeping was "Della mercatura e del mercante perfetto," written by Benko Kotruljic (born in Dubrovnik, 15th century). Its French translation appeared under the title "Parfait négociant" in Lyon in 1613.

The NAHSTE project, based at the University of Edinburgh and funded by the Research Support Libraries Programme (RSLP), was designed to open up a variety of outstanding collections of archives and manuscripts held at the three partner Higher Education Institutions (HEIs), and to make them fully accessible on the Web. The project also shows linkages to related records held by non-HEI collaborators

Outline: "Bohm, Bell - and Boom! The End of Modern Dualism"

The End of Cartesian Dualism: Physics (re)discovers Philosophy: over against Cartesian and especially 19th ct. positivist dualisms which separate physics and philosophy - the emergence of quantum mechanics forces physicists to be become philosophers again. Indeed, the logic of complementarity which q.m. requires ripples into a larger (re)turn to complementary relationships between physics, philosophy, and religion.

Welcome to the web site of the Interdivisional Group of History of Physics of the European Physical Society. We hope you will have a pleasant and interesting navigation!

This site has been organised as an introduction to the Group's activities. For a general introduction to the field of History of Science visit the site of the Division of History of Science of the International Union of the History and Philosophy of Science.

El origen de la Sociedad Mexicana de Historia de la Ciencia y la Tecnología (SMHCT) se encuentra asociado al Primer Coloquio Mexicano de Historia de la Ciencia (1963), organizado por el doctor Enrique Beltrán. Después de esta reunión, un grupo de historiadores de la ciencia encabezados por el doctor Beltrán y el doctor José Joaquín Izquierdo fundaron la SMHCT en 1964. De sus labores destaca la publicación de cinco volúmenes de la revista Anales de la SMHCT entre 1965 y 1979, y dos de la Memoria del Primer Coloquio.

This work is one of the most influential in history. The famous
phrase, "COGITO ERGO SUM" (I think, therefore I am) is a central
theme. Descartes' beliefs on that dual nature of mind and body,
and his emphasis on the role of doubt in all inquiry, formed the
basis for centuries of science and social thought.
