👉 Lyman's Law, also known as the Rayleigh-Taylor instability, is a fundamental theory in fluid dynamics that describes how the concentration and density of gas molecules within a liquid or gas mixture can change over time due to the interaction with the surrounding medium. It was introduced by physicist Sir Robert Lyman in 1896 and has since been widely used to predict the behavior of gases at high temperatures, where it is called Rayleigh-Taylor instability.
