Chemistry and Its Importance

Chemistry – earlier study of alchemy (an art of transforming common metals to precious metals, usually lead to gold but to no success) (alchemy has since been proven to be a wrong and currently dead branch of science)

Founder of Modern Chemistry (try and read up on the history of these two great men)

1. Robert Boyle (1627-1691) – performed controlled experiments and published his work with elaborate details such as procedure, apparatus and observations.
2. Antoine Lavoisier (1743-1794) – developed the Law of Conservation of Mass and the theory of combustion.
