Because the question of growth is a generalized physical system organizational development problem crossing all scales of space, time and phenomena. You find it everywhere, it has enormous relevance to all fields, and there are highly useful universal principles for what to expect and how to explore it's internal processes. Granted, it's a pattern of unstable and changing organization, so it does not have a fixed decription, so a different approach is needed. Still, it's one of the core physical phenomena that produce the forms that are stable and is the kind of subject physics should have useful global models for so people can know what they're working with. We've got no guidance to offer those who have tied the health of the planet to physically reorganizing our life support system at exponentially accelerating rates forever, for example. ... followed by oh, well... left out the essential qualification of "observable" when referring to "all" scales of space and time. It's hard to conclude much about things you cant's watch happening, too large or too small, too fast or too slow, or, like quantum events, having no process yet identifiable at all.... > OK, why is growth a physics problem and not, say, an algebraic topology > problem > or a genetic regulatory net problem, or an epigenesis problem, or a > sociology problem, > or something?

When one has a series of measurements of something, a bunch of dots, there are two basic choices. You can look at them as an equation to be described, connecting them in the plane of the page. You can also look at them as physical processes to be found, not directly connecting the dots to each other, but indirectly connecting them through other things. That links the dots through loops perpendicular to the page. Math is parallel to the page, processes perpendicular. Together they provide useful independent dimensions of understanding made possible by measurement. There's a very useful corollary of the conservation laws, following from their implication that rates of change and their derivatives can not be infinite. For things to begin or end there must be periods during which all rates of change are of the same sign, and fall between upper and lower bound exponential curves. That's a reasoning that could equally lead to the conclusion that there had to be an inflationary period in the big bang. I'm not certain the principles used are the same, but there's a similarity. What's new for the scientific method in this, though, is that you can see the same phenomenon in most any sort of beginning or ending too. It provides a very useful standard hypothesis for probing the clues of how events that begin and end occur. Math and process reasoning can be used together, or you can ignore one or the other. Each deals with the same world in a different way. For just one example, building an equation that has the same structure from beginning to end to represent any natural process of change, will not help much for picking out what actually happening. Carefully filtering data to reveal its independent shapes and their start and end points, on the other hand, can coax clues from the data about many new kinds of events. The main reason that's useful, of course, is there's lots there to see, frequently evolving systems.
