Steve: It is more accurate for me to say, the observation is, process in the Universe tends to consume all gradient. Tends is a traffic ticket shy of an absolute law. However, you really must struggle to find exceptions, and even those tend to be local and transient. The Universe has the game rigged if all process ultimately leads to a uniform 3 deg K cloud of samness(lack of not only all valued gradient, but ... all gradient.) For purely physical gradients, this is widely true. There may be fring examples of natural process which tend to amplify gradient, especially locally. We could apply that to out of all control run away radioactive chain reaction. Of cource, in the end, what is the result? Where once there was a concentration of fissile material -- a local gradient -- in the end there is heat, and so on, towards that 3 deg K terminus. But lets apply the concept even to 'love'. For Universe, subsititute 'the challenges of life.'(Not really much of a substitution, is it?) Without care and feeding, the pressures of life will consume what was once an intense love, and leave in its place cold ashes. The license is 'tends'. Not always. With care and feeding, we can guard and cherish the valued gradients in our lives, and when you think of it, often times at the cost of consuming other gradients in order to accomplish that. As well, in order to maintain and cherish love over decades, it is often necessary to court gradient even in the nature of how we love; if we try to maintain it by standing still, it will often wither. That which makes that a trueism(as opposed to an absolute law)is what tends to consume love. Gradient is simply a difference in something with respect to something else, usually space or time. The gradient we are most familiar with is a 'hill', an incline. What varies is the height above some equal potential energy level in a gravity field. (And if you wait long enough, the very forces of nature will tend to consume that hill. Bits at the top will roll to the bottom.) But there can be gradients of anything with respect to time or space (or anthing else as the second axis, but most often time and space.) Consider 'you.' There is an abrupt difference in the amount of 'you' with respect to space at your skin; there is an abrupt difference in the amount of 'you' with respect to time at your birth and death. Our very existence in this universe is dependent on gradient, not only for identity and uniqueness, but to exist at all. And over time, the Universe tends to consume that gradient. The gradient 'you' does not last forever. You can in fact consider there to be a gradient field which at all locations in space points in the direction of the greatest increase in the amount of 'you' in the Universe. That is a kind of gradient field in three dimensions. Same thing with temperature; temperature is not (yet, but in theory, someday will be)not unitform everywere in the universe. We observe that something called 'heat' will tend to flow from a hotter mass to a colder mass, resulting in an intermediate warm mass. We can consider there to be a local gradient field of temperature with respect to space. We often locally take advantage of that gradient field ,,, for as long as we can. Because the Universe tends to act, with its processes, in a manner which consumes that gradient field. Same with pressure. Same with lots of things. Concentrations of species. When we concentrate things, without care and isolation, natural processes will tend to diffuse and reduce that gradient of concentration. Sometimes, locally, processes increase gradient for a time, but over enough time, those intermediate gradients are eventually consumed. An example is, species in solution in a gravity field(an ordering gradient.) The species will settle out as sedimentation, and form rough layers by density. And for a while, will represent ordered layers of species. But over time, natural processes will also tend to amelioreate those gradients... diffusion, erosion. Eventually, disorder wins, and in forming local order, we tend to do so at the cost of additional disorder. So we must choose our orderings wisely based on what we value, which is also tied to gradient. When you look into human physiology, you see gradient everywhere, driving everything. Same with the Unverse. When you consider economies, for sure, gradients drive everything. Gradient is the most relied upon and least considered aspect of existence. Something so 'true' that it is widely ignored. Humans live entire lifeimes without ever once pondering 'gradient.' But just like one of the three famous things that even God cannot do in his Universe(create a plane triangle with more that 180 included degrees), those humans are unable to avoid their dependence on gradient to exist. The Universe without gradient is nothing. Life without gradient is death, and even the final transformative processes of death involve our last ride on gradient. regards, Fred (Edited by Fred Bartlett on 5/17, 7:50am) (Edited by Fred Bartlett on 5/17, 7:53am)
