Images of Chemical Laboratories over the Course of History
The rise of modern chemistry is the result of meticulous detective work guided by specific assumptions. In the chemical laboratories of the eighteenth and nineteenth centuries, countless experiments are performed to determine which substances react with each other in which proportions. After many wasted efforts, researchers finally comprehend changes of substances qualitatively and quantitatively on the basis of assumptions about unchangeable “atoms” of the elements and the bonding of these atoms to “molecules” of the remaining substances.
