CONTEMPORARY EVENTS IN SCIENCE (1400-1799)

CONTEMPORARY SCIENCE, TECHNOLOGY, ART (1400-1799)

The influence of printing on the development of science was enormous.
By the easier dissemination of knowledge scientific communication was encouraged.

(ca. 1600): Works of little importance that probably are drawn, in part, from PARACELSUS. GLAUBER: excellent practical chemist and reliable recorder. Substituted water for mercury in the TRIA PRIMA of PARACELSUS. "FURNI NOVI PHILOSOPHICI"---well described observations and many new experiments. "MIRACULUM MUNDI"--- Exaggerated account of his "sal-mirabile" (Na₂SO₄^.10H₂O---"Glauber's Salt"). SYLVIUS: extends VAN HELMONT'S ideas of chemical physiology. Diseases generally due to hyperacidity or hyperalkalinity.

Newton suggests force of chemical attraction: "All the operations therefore which chemistry performs on bodies are mere changes in respect of Motion...A body may be changed...when there is a transposition of its constituent parts."	1650	1687:NEWTON's "PRINCIPIA." 1690:HUYGENS--- "TRAITÉ DE LUMIERE." 1698:SAVERY--- Steam pump.
BEGINNINGS OF ORGANIC AND BIOLOGICAL CHEMISTRY Much anatomical and physiological work prior to 1700 (see Iatrochemistry) contributed to the beginnings of physiological chemistry.
1712: NEWCOMEN--- Steam engine. 1714:FAHRENHEIT--- Mercury thermometer. 1735: LINNAEUS--- "SYSTEMA NATURAE." 1743: Founding American Philosophical Society 1745: Leyden jar condenser. 1751: FRANKLIN--- "EXPERIMENTS AND OBSERVATIONS ON ELECTRICITY 1756: Cement first made. 1761: MORGANI--- "DE SEDIBUS ET CAUSIS MORBORUM" 1768:WATT--- Hot cylinder and separate condenser. F.M. VOLTAIRE DAVID HUME IMMANUEL KANT J.J. ROUSSEAU	1700	BEGINNINGS OF ANALYTICAL CHEMISTRY Earlier (~1500) assaying of ores. VAN HELMONT (1577-1644): The qualities of the metals persist in their solutions. TACHENIUS (ca. 1620-1690): Devised the rudiments of one of the first qualitative analysis systems.

LAVOISIER: First determination of respiratory quotient. 1773: ROUELLE: Composition of plant ash. BERGMAN: extensive works on analysis, especially water. Comparative analysis of iron and steel. ca. 1774: BERGMAN: FIXED AIR (CO₂): AERIAL ACID. Recognized three constituents of air: AERIAL ACID. Inert part. Combustible part, = PURE AIR. Tabulated chemical affinities. Classified minerals by chemical constitution. 1775: "DE ATTRACTIONIBUS ELECTIVIS."
