Robert Boyle (1627-1691)
Johann Kerseboom (c. 1689)
Boyle was an Irish chemist who published The Sceptical Chymist which argues against Aristotle's view of the four elements: Earth, Air, Fire and Water in favor of matter consisting of corpuscles (atoms). He also worked with 'rarefied' air (low pressure and vacuum) and discovered sound does not travel in vacuum and animals need air to live. Boyle's ideal gas law shows at constant temperature, change in pressure are inversely proportional to the change in volume.
