Who was Lavoisier? What problems did Lavoisier address (and why)? =====
Intro/Review
Discussion: 1775 memoir on combustion
Discussion: 1783 memoir on water
Discussion: When was oxygen discovered?
Epilog
Legacy of the "Scientific Revolution"
- interpreting nature: Burnet's natural history
- experiment: Boyle's air pump
- systematic investigation: Gilbert's magnetic terella
- measuring
- institutions: French Academy of Science
- system for reporting results
- new ideas: natural laws
- scale of patronage & enterprise
Two Lineages of Chemical Ideas
- Isaac Newton
- Newton's Opticks
- Etienne Francois Geoffroy and Newtonian concept of affinities
- Geoffroy's affinity table
- later table, with lab
- industries supporting chemists
- Paracelsus, Johann Becher and Georg Ernst Stahl
- phlogiston
- reduction of ores to metals by smelting with charcoal's phlogiston
- metals and their calxes
- release of phlogiston: combustion, calcination, rusting, tarnishing, corrosion
- plants
- discovery & burning of phosphorous
Pneumatics
- Stephen Hales
- Joseph Black
- Joseph Priestley & his "pyrmont" water
- Henry Cavendish
- Karl Wilhelm Scheele
- Priestley's pneumatic trough
Lavoisier & his Puzzles
