Cosmologists Try a New Way to Measure the Shape of the Universe
Is the universe flat and infinite, or something more complex? We can’t say for sure, but a new search strategy is mapping out the subtle signals that could reveal if the universe has a shape.
New Book-Sorting Algorithm Almost Reaches Perfection
The library sorting problem is used across computer science for organizing far more than just books. A new solution is less than a page-width away from the theoretical ideal.
The Jagged, Monstrous Function That Broke Calculus
In the late 19th century, Karl Weierstrass invented a fractal-like function that was decried as nothing less than a “deplorable evil.” In time, it would transform the foundations of mathematics.
Concept Cells Help Your Brain Abstract Information and Build Memories
Individual cells in the brain light up for specific ideas. These concept neurons, once known as “Jennifer Aniston cells,” help us think, imagine and remember episodes from our lives.
Heat Destroys All Order. Except for in This One Special Case.
Heat is supposed to ruin anything it touches. But physicists have shown that an idealized form of magnetism is heatproof.
Mathematicians Discover New Way for Spheres to ‘Kiss’
A new proof marks the first progress in decades on important cases of the so-called kissing problem. Getting there meant doing away with traditional approaches.
Can AI Models Show Us How People Learn? Impossible Languages Point a Way.
Certain grammatical rules never appear in any known language. By constructing artificial languages that have these rules, linguists can use neural networks to explore how people learn.
The Physicist Decoding the Nonbinary Nature of the Subatomic World
Inside the proton, quarks and gluons shift and morph their properties in ways that physicists are still struggling to understand. Rithya Kunnawalkam Elayavalli brings to the problem a perspective unlike many of their peers.
Rational or Not? This Basic Math Question Took Decades to Answer.
It’s surprisingly difficult to prove one of the most basic properties of a number: whether it can be written as a fraction. A broad new method can help settle this ancient question.
