This is actually what inspires me as a physicist. So back in the day people were looking for an encapsulated theory of why the hell things happened. The Principle of Least Time was the original theory, but that didn't make sense (look at a spring) so then there was The Principle of Least Energy, but that also wasn't good enough. Until Hamilton came along and gave us the Principle of Least Action. This is the basis for all physics. All of our laws incorporate this theory. Einstein took it one direction and Maxwell took it another and Planck another. So all of these phenomena are basically the same. Just different manifestations. Physics isn't 10,000 problems it's 10,000 manifestations of like 5.
