‎The theme of materials in the history of technology has never been as well researched as other more popular areas like energy, production technology or transport and communication. The present collection of papers originating from the symposium on "Materials: Science, Technology and Early Applications" in conjunction with the 20th International History of Science Congress in Liege, 1997, make a contribution to remedying this unsatisfactory situation. They concentrate on the 19th and 20th centuries and range from research on the metallurgy of zinc in the late 18th and early 19th century to the prospects of ceramic materials to ameliorate contemporary environmental problems. Languages : English, French, German.‎

‎Addressing modern physics in its largest perspective, the present volume, which includes 34 contributions, begins with a reappraisal of classical science. However, the stress is placed on the contemporary period with sections devoted to thermodynamics and mechanics, the centenary of the electron, Einstein, the quantum theory and particle physics.

‎The exceedingly rare first edition of the first work to describe the construction of the adjustable proportional compass – the first work to describe both its construction and its application. The adjustable proportional compass became an indipensable tool for calculations and measurements for over three centuries. The proportional compass was a seminal calculating instrument in use from the end of the sixteenth century until the nineteenth century. Consisting of two rulers of equal length joined by a hinge, it was a precursor to the sector and could be used for solving problems in proportion, multiplication and division, geometry, and trigonometry, and for computing various mathematical functions, such as square roots and cube roots. The sector derives its name from the fourth proposition of the sixth book of Euclid, where it is demonstrated that similar triangles have their like sides proportional. Some sectors also incorporated a quadrant, and sometimes a clamp at the end of one leg which allowed the device to be used as a gunner's quadrant. “The device was apparently first developed by Joost Bürgi and first published by Levinus Hulsius (1604). Hulsius offered the instrument for sale and thus limited himself to instructions for its use and did not detail its construction. The present work provides construction details on the hindge and the creation of the scales.” (Tomash & Williams). The sector was invented, essentially simultaneously and independently, by a number of different people prior to the start of the 17th century. Credit for the invention is often given to either Thomas Hood (who did not claim priority himself), a British mathematician, or to the Italian mathematician and astronomer Galileo Galilei. Galileo, with the help of his personal instrument maker Marc'Antonio Mazzoleni, created more than 100 copies of his proportional compass design and trained students in its use between 1595 and 1598. Of the credited inventors, Galileo is certainly the most famous, and earlier studies usually attributed its invention to him. James Kynvyn, Robert Beckit and Charles Whitwell all at some point also seem to have claimed to priority of the invention.Giordano Bruno, shortly before his death, also saw its potential. It could measure the infinitesimal fractions of the angular degrees and calculate the proportions between lines, geometric shapes and solids, working on the proportionality and commensurability of angles and segments. This new precision in calculations confirmed Bruno’s thesis of the existence of the physical minimumas opposed to the Aristotelian thesis of the infinite divisibility. (see: Zaffino, Giordano Bruno and the Proportional Eight Spike Compass) The many claims of invention, however, do not deprive Horcher of being the very first to describe the actual construction of the instrument, thus being of seminal importance in its widespread use over more than three hundred years.
