Weird Circles Keep Popping Up Around the World. Alan Turing Predicted Them in 1952.

From Popular Mechanics

A pattern described by computer science icon and polymath Alan Turing continues to show up in new scientific research 70 years later. The “Turing pattern” is a widespread phenomenon where noisy systems form stable patterns after being stimulated. The latest example is in “symmetrically spaced” patches of desert grasses, which grow in naturally orderly equilibrium to maximize each patch’s access to limited water.

➡ The world is weird as [email protected]#!. Let’s explore it together.

In Africa and Australia, desert grasses grow in what are called fairy circles. In the new study, published in the Journal of Ecology, scientists explain:

“This pattern has been explained with scale-dependent ecohydrological feedbacks and the reaction-diffusion, or Turing mechanism, used in process-based models that are rooted in physics and pattern-formation theory.”

But modeling a true Turing pattern isn’t as simple as pointing and labeling. Scientists must analyze, which is more challenging
