Robert Boyle is widely regarded as one of the key founders of modern chemistry and is today best remembered for Boyle's Law, which states that at a fixed temperature the volume of a given gas is inversely proportional to the pressure exerted by that gas. The three works included represent key foundations of modern scientific thought regarding gemology and deep-sea science.
