Parents' fear of math linked to lower achievement in children

Mathematics anxiety is a feeling of tension and fear when dealing with numbers or performing calculations. It is a common form of academic anxiety: according to an OECD report, around 40% of students feel nervous, helpless ...

Quantum statistical approach quiets big, noisy data

Big data has gotten too big. Now, a research team with statisticians from Cornell has developed a data representation method inspired by quantum mechanics that handles large data sets more efficiently than traditional methods ...

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 ...

Statistical physics rejects theory of 'two Ukraines'

When reading news and analyses of the Russian invasion of Ukraine, researchers in Spain perceived many conflicting messages being transmitted. The most notable one is the theory of "two Ukraines" or the existence of ideologically ...

A new mathematical model of cellular movement

A mathematical model that describes how cells change their shape during movement suggests that the movement is mainly driven by the contraction of the skeletal proteins, called "myosin." The new model developed at Penn State ...

Copying others can lead to greater comfort with riskier behavior

The best things in life are unlikely to occur. In many situations, taking at least moderate risks yields higher expected rewards. Yet many people struggle with taking such risks: they are overly cautious and forego high payoffs. ...
