François, suricate nihiliste

@jaztrophysicist A short #dataviz for a forthcoming local communication by the regional supercomputing center CALMIP, to illustrate our recent results on the measurement of turbulent magnetic diffusion at the solar surface.

The convection turbulent velocity field at the solar photosphere, with a resolution of 2500km and a time-sampling of 15 minutes, over a consecutive time-window of 6 days, was computed on the supercomputer based on 4096^2 NASA/SDO images of the photosphere with 45seconds sampling. Images on the right represent the distribution of magnetic fields at the photospheric level of the Sun, also obtained from the SDO MDI instrument. #astrodon #fluids #turbulence #science #ComplexSystems

How do government software systems break—and how can we fix them?

Mikey Dickerson (healthcare.gov rescue, USDS) talks with @patio11 about procurement, crisis engineering, and why modernization plans often make things worse before they get better.

A great listen for anyone in civic tech or public service.

Most textbook examples use somewhat boring monochrome visuals for Cellular Automata. In a series of posts, I’m exploring how to bring these lifelike systems to life through color. Here's the first one, where I experiment with color gradients to paint evolving landscapes.

📝 🧀 Meltdown of trust in weakly governed economies.

“Neoliberal capitalism has created untrustworthy people and has (understandably) eroded not just trust in government but trust in private institutions and trust in each other. It has created a system that devours itself. None of this, however, is inevitable.”

paper arguing that it is essential to understand trust in well-functioning societies.

Dislike of general opinion makes for tight elections

Many sociophysics models based on Ising model favor a strong majority. The article introduce the influence of opinion polls on the electorate into the model.

Opinion polls bring a new phase in which two groups divide the opinion equally. These political camps are spatially segregated, and the sharp boundary that separates them makes the system
size dependent, even in the limit of a large electorate.

"Election data show that, since the early 1990s, countries with more than about a million voters often found themselves in this state, whereas elections in smaller countries yielded more consensual results. We suggest that this transition hinges on the electorate’s awareness of the general opinion."
