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

Turing Award winners endorse Biden, say Trump immigration policy will stifle tech research

Twenty-four winners of the Turing Award are endorsing former Vice President Joe Biden in the upcoming presidential election, The New York Times reported, explaining they’re concerned the Trump administration’s immigration policies could be detrimental to both computer research and the technology industry over the long term.

“The most brilliant people in the world want to come here and be grad students, but now they are being discouraged from coming here, and many are going elsewhere,” David Patterson, a Google distinguished engineer and former professor at the University of California, Berkeley told the Times.

Among the names on the endorsement are Vint Cerf, who co-designed TCP/IP protocols and the architecture of the internet; Martin Hellman, who invented public key cryptography; Ed Catmull, co-founder of Pixar; Facebook AI scientist Yann LeCun; and Barbara Liskov, known for her work in designing computer programming languages.

“It is unprecedented for winners of the top
