Since we became a (semi) intelligent species and started studying the cosmos, humanity has been on a long journey to realizing we are not the center of the universe, the galaxy, or even the Solar System. While disappointing for an egotistical species, this realization has led us to discoveries about the real nature of our universe, or at least models …

But the methods were no longer effective when mathematicians only wanted to find, say, the number of real solutions to the equations in an enumerative geometry problem, or the number of integer solutions. If they asked an enumerative geometry problem in any number system other than the complex one, inconsistencies cropped up again. In these other number systems, mathematicians couldn’t …

“Anything that is polysyllabic and Latinate doesn’t sound threatening enough,” said Michael Ghil, a mathematician at the University of California, Los Angeles, who studies theoretical climate dynamics. “‘Tipping points’ does.” The idea that there had been major shifts in the Earth’s climate was by then well established. Scientists had found geological evidence that supported the Snowball Earth hypothesis. They’d seen …

Barrier-grid animations (also called scanimations) are a thing most people would recognize on sight, even if they didn’t know what they were called. Move a set of opaque strips over a pattern, and watch as different slices of that image are alternately hidden and revealed, resulting in a simple animation. The tricky part is designing the whole thing — but …

WASHINGTON (AP) — A decade-long slide in high schoolers’ reading and math performance persisted during the COVID-19 pandemic, with 12th graders’ scores dropping to their lowest level in more than 20 years, according to results released Tuesday from an exam known as the nation’s report card. Eighth-grade students also lost significant ground in science skills, according to the results from …

New test scores from the National Assessment of Educational Progress (NAEP), also known as the Nation’s Report Card, show eighth-graders’ science scores have fallen 4 points since 2019 and 12th-graders’ math and reading scores have fallen 3 points in the same time period. The tests were administered between January and March 2024. This is the first NAEP score release since …

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the security of modern encryption. Any clever trick for solving them will doom most forms of cryptography. Several years ago, researchers found a radically new approach to encryption that lacks this …

But just how much harder? In 1962, the mathematician Tibor Radó invented a new way to explore this question through what he called the busy beaver game. To play, start by choosing a specific number of rules — call that number n. Your goal is to find the n-rule Turing machine that runs the longest before eventually halting. This machine …
