“Democracy is the theory that the common people know what they want and deserve to get it good and hard”*…


democracy 2

It probably goes without saying at this point, but democratic institutions are experiencing something of a crisis. The last decade has seen an increasing trend toward right-wing populism around the world, from Donald Trump in the US and Jair Bolsonaro in Brazil to the rise of autocratic regimes in Poland and Hungary. These developments are particularly troubling considering they are occurring in countries ruled by nominally democratic governments, even though democracy is meant to be a bulwark against exactly this kind of political extremism.

Although political theorists have long considered democratic governments to be among the most stable forms of governance, new research by an international team of complex systems theorists that analyzes how democracies become destabilized suggests that the stability of democratic governments has been taken for granted. As detailed in a paper published this week in the European Journal of Physics, Wiesner and an international team of mathematicians, psychologists, political theorists, and philosophers focused on two features of complex social systems—feedback loops and stability—to better understand why democracies around the world are backsliding…

A team of systems experts argue that the decline of democracies is poorly understood, but that concepts from complex systems theory may offer a solution: “Complex Systems Theorists Explain Why Democracy Is Dying.”

* H. L. Mencken, who also (prophetically?) observed: “As democracy is perfected, the office of president represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart’s desire at last and the White House will be adorned by a downright moron.”


As we get down with governance, we might send carefully-researched and elegantly-written birthday greetings to Thomas Carlyle; he was born on this date in1795.  A Victorian polymath, he was an accomplished philosopher, satirical writer, essayist, translator, historian, mathematician, and teacher.  While he was an enormously popular lecturer in his time, and his contributions to mathematics earned him eponymous fame (the Carlyle circle), he may be best remembered as a historian (and champion of the “Great Man” theory of history)… and as the coiner of phrases like “the dismal science” (to describe economics)

Carlyle’s History of the French Revolution, a three volume work that assured his fame as a historian, was finished in 1836 but not published until 1837 because John Stuart Mill’s maid mistook the manuscript of Volume One for kindling.  The setback prompted Carlyle to compare himself to a man who has nearly killed himself accomplishing zero.”   But he re-wrote the first volume from scratch.

“A well-written Life is almost as rare as a well-spent one.”   – Thomas Carlyle



Adventures in Cosmology: Starting out Simply…

Why was entropy so low at the Big Bang? (source: Internet Encyclopedia of Philosophy)

Back in 2010, SUNY-Buffalo physics professor Dejan Stojkovic and colleagues made a simple– a radically simple– suggestion:  that the early universe — which exploded from a single point and was very, very small at first — was one-dimensional (like a straight line) before expanding to include two dimensions (like a plane) and then three (like the world in which we live today).

The core idea is that the dimensionality of space depends on the size of the space observed, with smaller spaces associated with fewer dimensions. That means that a fourth dimension will open up — if it hasn’t already — as the universe continues to expand.  (Interesting corollary: space has fewer dimensions at very high energies of the kind associated with the early, post-big bang universe.)

Stojkovic’s notion is challenging; but at the same time, it would help address a number of fundamental problems with the standard model of particle physics, from the incompatibility between quantum mechanics and general relativity to the mystery of the accelerating expansion of the universe.

But is it “true”?  There’s no way to know as yet.  But Stojkovic and his colleagues have devised a test using the Laser Interferometer Space Antenna (LISA), a planned international gravitational observatory, that could shed some definitive light on the question in just a few years.

Read the whole story in Science Daily, and read Stojkovic’s proposal for experimental proof in Physical Review Letters.

As we glance around for evidence of that fourth dimension, we might bid an indeterminate farewell to Ilya Prigogine, the Nobel Laureate whose work on dissipative structures, complex systems, and irreversibility led to the identification of self-organizing systems, and is seen by many as a bridge between the natural and social sciences.  He died at the Hospital Erasme in Brussels on this date in 2003.

Prigogine’s 1997 book, The End of Certainty, summarized his departure from the determinist thinking of Newton, Einstein, and Schrödinger in arguing for “the arrow of time”– and “complexity,” the ineluctable reality of irreversibility and instability.  “Unstable systems” like weather and biological life, he suggested, cannot be explained with standard deterministic models.  Rather, given their to sensitivity to initial conditions, unstable systems can only be explained statistically, probabilistically.
