How Many Trees Can Share a Branch?

The Unexpected Geometry of Trees Imagine a vast network, a sprawling city of connections. Each road represents a link, and every path from one point to another is a unique journey. Now, imagine a collection of these journeys, each a distinct route, yet all sharing a common thread – a significant overlap in the roads…

Public Transit’s New Math: Scheduling Chaos into Harmony

For years, creating efficient public transportation schedules has been a logistical nightmare. Think of coordinating countless trains, buses, and trams, all with varying frequencies, ensuring smooth transfers, and minimizing passenger wait times. It’s a problem so complex, it’s often tackled by approximating the reality, sacrificing accuracy for computational tractability. But what if there was a…

Whispers from Africa: AI Learns to Listen in 2,300 Languages

The Untapped Potential of African Languages Africa, a continent pulsating with a vibrant tapestry of over 2,300 languages, has largely remained unheard in the digital world. Speech technology—the ability of computers to understand and generate human speech—has primarily focused on a handful of dominant languages, leaving a vast linguistic landscape unexplored. This digital silence excludes…

AI predicts airflow, ignoring most of the data

Researchers at ONERA and the Institute of Mathematics of Toulouse have developed a new AI-powered method for simulating fluid flows. Forget about meticulously feeding your algorithm every single data point. This method, surprisingly, can accurately predict airflow patterns even when it’s missing the vast majority of data points. It’s like having a hyper-intuitive weather forecaster…

When Randomness Slows Down Time

The Unpredictable Dance of Random Walks Imagine a tiny particle, adrift in a chaotic landscape. Its movements aren’t governed by predictable laws, but rather by the whims of chance. This seemingly simple scenario, known as a random walk, underpins many complex processes in nature and technology, from the diffusion of molecules to the spread of…

A New Map of Degenerate Surfaces: Charting the Boundaries of Geometry

Researchers at Tohoku University, the University of Tokyo, the University of Nottingham, and Academia Sinica have created a new classification of surfaces, called Horikawa surfaces, pushing the boundaries of our understanding of their geometry. These surfaces are a type of algebraic surface—a shape defined by polynomial equations—that sit intriguingly close to a line representing a…
