Over the next year, Domokos and his colleagues used geometric thinking to unpack the rules of molecular self-assembly — devising a new way to constrain the mosaics that molecules can form, using only the simple geometry of tessellation. “At first, they did not believe that you can do it,” Domokos said. “They were doing artificial… Continue reading The Simple Geometry That Predicts Molecular Mosaics
To Unions, Organizing Time Is Fine When It’s on the Taxpayers’ Dime
Randi Weingarten, the powerful president of the American Federation of Teachers, hasn’t been a working teacher in more than a quarter of a century. Randi Weingarten: The teachers union boss hasn’t taught in decades, yet has accrued a lot of service time. But, she protests, not $230,000 worth of public pension payments over 15 years.… Continue reading To Unions, Organizing Time Is Fine When It’s on the Taxpayers’ Dime
Do Insects Feel Joy and Pain?
In the early 1990s, when I was a Ph.D. student at the Free University of Berlin modeling the evolution of bee color perception, I asked a botany professor for some advice about flower pigments. I wanted to know the degrees of freedom that flowers have in producing colors to signal to bees. He replied, rather… Continue reading Do Insects Feel Joy and Pain?
Mathematicians Discover New Way to Predict Structure in Graphs
It has been an exhilarating year in combinatorics research. In early 2023, mathematicians were stunned when two of the biggest problems in the field were solved in as many months. Now, a third major question has fallen with a 14-page proof “that has absolutely all the right ideas,” said Mehtaab Sawhney of the Massachusetts Institute… Continue reading Mathematicians Discover New Way to Predict Structure in Graphs
Computer Scientists Inch Closer to Major Algorithmic Goal
“In other words,” Sun said, “in order to further improve graph isomorphism, group isomorphism is a big bottleneck.” A Problem Transformed When progress on a problem stalls as long as it did for group isomorphism, invention is usually necessary to get unstuck. “When you have a big advance, that should be some indication that there’s… Continue reading Computer Scientists Inch Closer to Major Algorithmic Goal
Military Assistance to Ukraine Is a Rare Success
Last week, the United States reversed its long-standing opposition to sending Ukraine F-16 advanced aircraft to aid its fight against Russia. The Biden administration previously had expressed concerns that the jets would be too sophisticated for the Ukrainians and that providing the American-made aircraft could lead to escalation with Russia. Ukraine’s impressive, continued battlefield success… Continue reading Military Assistance to Ukraine Is a Rare Success

In New Paradox, Black Holes Appear to Evade Heat Death
The AdS/CFT duality has been reliably blowing people’s minds for over 25 years. It’s hard to visualize how such different systems as a black hole and a hot plasma could be equivalent. Now it seems that the difficulty is not just a failure of the human imagination, but a feature of the mathematics. As a… Continue reading In New Paradox, Black Holes Appear to Evade Heat Death
