Undoubtably I was not the first to make the observation. However, when I first "articulated" (or blurted?) the Law in the Geodynamics and Paleomagnetism course at the University of Arizona, Professor Bob Butler promptly named the idea "Andrew's Law". It turns out this Law is a fairly important and universal concept that applies to any science considering events of the past. We can know much about the very moment we live in- the very edge of time which is the present, where the passing "plane" of time intersects the "plane" of our physical universe. But as soon as that time is passed, the rate of information loss is rapid. Geologists are ruled by this law. Still, it is the chosen task of geologists to reach back in time and try to extract any information- from the scraps of material we can find which may have formed in that time, leaving a tiny clue revealing the conditions at the time of formation.
