Megastudy finds a simple way to boost math progress

American students have been falling behind in math for decades—with test scores that consistently rank in the bottom 25% globally compared to students in other developed countries—and the COVID-19 pandemic made the situation ...

Dudeney's 120-year-old dissection puzzle solution proves optimal

In 1907, the English author and mathematician Henry Ernest Dudeney posed a puzzle: Can any equilateral triangle be cut into as few pieces as possible that will fit together to form a perfect square? Four weeks later, he presented ...

Nessie loves a sunny summer's day—how anecdotes become data

New research from the University of St Andrews has used a database of Loch Ness Monster reports to translate anecdotes into data, shedding light on statistical biases and the importance of defining the right information for ...

Studying complex criminal networks with new statistical tools

The word "network" has become part of our everyday language, in particular since the rise of online social networks. However, human interactions are not only aimed at sociability and fun. Criminals also interact with each ...

Perturbing the Bernoulli shift map in binary systems

Is it possible for a deterministic system to be unpredictable? Although counter-intuitive, the answer is yes. Such systems are called "chaotic systems," which are characterized by sensitive dependence on initial conditions ...

Mathematicians explain how some fireflies flash in sync

Stake out in Pennsylvania's Cook State Forest at the right time of year and you can see one of nature's great light shows: swarms of fireflies that synchronize their flashes like strings of Christmas lights in the dark.
