In A Swirl At The White House
In thermodynamics, entropy is a measure of the energy unavailable for useful work. It is (and, yes, I had to look it up) both a reflection of disorder and a trend line; an isolated system proceeds in the direction of maximum entropy. The description feels disconcertingly apt for the chaotic reality of the Obama administration's second term.
That part I didn't have to look up. It's swirling all around.
