Frontpage FeedThermodynamics vs Kinetics
Suppose there was a treehouse that was shoddily built. There weren't enough wooden planks, and the ones that were there were held in place by rusty nails. Further, the tree on which it was built was old and rotting, and located in an area prone to wind gusts.
You could justifiably make a statement as to the current state of the treehouse relative to a possible future state. Namely, its current state is up in a tree, but some time in the future, the pieces of wood would be lying on the ground, along with any unlucky children that might be atop it at the wrong moment.
You might say that the current state of the treehouse is unstable. In the future, it will be in a more stable, though also more disordered, state. You might even say that there's a force pulling the treehouse from its current unstable state to its future more stable state.
Remembering back to my chemical engineering days, one of the concepts that seemed to transcend the field is difference between thermodynamics and kinetics. What I've described above is a statement of thermodynamics: how stable the current state of affairs is relative to some other state, which way the arrow of causality wants to move between the states, how strongly the pull is between one state and another.
Kinetics, on the other hand, would describe how fast the treehouse would move from its current state to the future state, what path it would take, what factors would speed up or slow down that change, etc. A kinetic analysis might involve the equation d=1/2gt^2.
Thermodynamics speaks simply to the stability of a system. It doesn't say how quickly or in what exact manner any change might happen; that's what kinetics is for.
Right now, the worldwide monetary system is in an extremely unstable state of affairs. The instability is caused by debt, fiat currency, and monetary inflation. We have ample thermodynamic knowledge of that fact. A more stable state of affairs lies at some point in the future: a world with much less debt, an end to fiat currencies, and lack of central monetary policy. What we don't have is kinetic knowledge: when that future world will come about, how quickly, and in what manner.
All we can do is try our best to protect ourselves from the current instability, and even those means are not obvious.
To be continued...
but we don't have an equasion for this problem
Right wing Christians use this approach to "prove" that God did or didn't do something or to "disprove" abiogenesis and evolution.
I learned thermo in terms of systems and energy crossing system boundries. I don't recall stability being an issue.
but we do have an equation for this problem
Go back and look at thermodynamics again. Perhaps you remember entropy... and not just the "heat flows from hot to cold" entropy, or that entropy > 0...but that the most stable system is the one with the most disorder because it has the highest probability of being in that state. Furthermore, systems will tend to move towards a higher order of entropy, or randomness (chaos). That isn't to say that they cannot move towards a lower entropy, but it requires energy that can not be retrieved.
To come back to his example. It required more energy to put the tree house in the tree than for the house to fall out of the tree. Without putting more energy into the system, the tree house's boards will become rotted, the nails will become rusted, and eventually the tree house will fall. It must!
What does this mean? It means that we have neglected to put positive energy into our financial system. We have failed to plan for the future and maintain our tree house. Unless we put a whole lot of work into refurbishing our system it will fall. In fact, it may need to be torn down and replaced all together.
And in case you were wondering about the equation... we would probably want to look at S = k ln W where k is boltzman's constant and W is the number of microstates consistent with the number of macrostates... although I hardly believe this equation relates to the topic (it was more for fun than anything else) , but it is does show that the most probable state of disorder will be the state that is the most chaotic.

An important fact about these diamonds is that they are not the ones which are unique in color because most of them are transformations in some form from the other colored diamonds.
