Inventing chemistry : Herman Boerhaave and the reform of the chemical arts by John C Powers( )

11 editions published between 2012 and 2016 in English and held by 861 WorldCat member libraries worldwide

In Inventing Chemistry, historian John C. Powers turns his attention to Herman Boerhaave (1668 & ndash;1738), a Dutch medical and chemical professor whose work reached a wide, educated audience and became the template for chemical knowledge in the eighteenth century. The primary focus of this study is Boerhaave & rsquo;s educational philosophy, and Powers traces its development from Boerhaave & rsquo;s early days as a student in Leiden through his publication of the Elementa chemiae in 1732. Powers reveals how Boerhaave restructured and reinterpreted various practices from diverse chemical traditio

3 editions published in 1988 in English and held by 9 WorldCat member libraries worldwide

This study reviews delineator spacing intervals of 40, 80 and 160 feet placed along median barrier divided roadways. Optimum spacing of the delineators was determined by having observers view film of several installations. Spacings of delineation were considered undesirable when, in the raters opinions, the delineators provided an inadequate amount of information to be considered an effective aid for nighttime driving. Primary considerations for driver information were the ability to detect the path of the road ahead and the lateral location of the barrier

Fire Analysis in the Eighteenth Century: Herman Boerhaave and Scepticism about the Elements( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract In the eighteenth century, many chemists asserted that chemical operations could not decompose a substance into its natural, constituent elements or principles. One such chemist was Herman Boerhaave (1668–1738), who claimed, following the work of Robert Boyle and Joan Baptista van Helmont, that examples of these alleged analyses were, in fact, not reductions of a body into elements, but rather the rearrangement of its particles by the fire. Since we cannot observe the shape and arrangement of particles directly, he reasoned, any claim regarding the elemental status of a substance was purely speculative and inadmissible in his chemistry. As a result, Boerhaave devised a system of chemistry which, in effect, accepted no elemental substances and which focused on understanding how the chemist's 'instruments, ' including fire and chemical menstrua, effected changes in matter. I conclude by showing how Boerhaave's conclusion had ramifications for later developments in chemistry, especially those of the French Stahlians and of Antione Lavoisier
