What began as Henry W. Grout’s curiosity about the world has grown to become recognized as the region’s cornerstone of history, culture and sciences. Accredited by the American Association of Museums, this resource has grown to four unique properties, the Grout Museum of History & Science, Bluedorn Science Imaginarium, Rensselaer Russell House Museum, and the Snowden House. Explore the future of the district with the Sullivans Veterans Project.

If the word hydraulics is understood to mean the use of water for the benefit of mankind, then its practice must be considered to be even older than recorded history itself. Traces of irrigation canals from prehistoric times still exist in Egypt and Mesopotamia; the Nile is known to have been dammed at Memphis some six thousand years ago to provide the necessary water supply, and the Euphrates River was diverted into the Tigris even earlier for the same purpose. Ancient wells still in existence reach to surprisingly great depths; and underground aqueducts were bored considerable distances, even through bedrock. In what is now Pakistan, houses were provided with ceramic conduits for water supply and drainage some five thousand years ago; and legend tells of vast flood-control projects in China barely a millenium later. All of this [1] clearly demonstrates that men must have begun to deal with the flow of water countless millenia before these times.

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.
