The temperature changes hour to hour and day to day; exchange rates behave no differently. Wherever studies of the variability of similar one-dimensional time series are concerned, analyses based on multifractals have managed to gain recognition. Now, these tools have been developed and successfully...

Western researchers have developed a novel technique using math to understand exactly how neural networks make decisions—a widely recognized but poorly understood process in the field of machine learning....

Hula hooping is so commonplace that we may overlook some interesting questions it raises: "What keeps a hula hoop up against gravity?" and "Are some body types better for hula hooping than others?" A team of mathematicians explored and answered these questions with findings that also point to new...

With billions of children around the world anxiously waiting for their presents, Father Christmas (or Santa) and his reindeer must be traveling at breakneck speeds to deliver them all in one night....

The manic pace of sharing, storing, securing, and serving data has a manic price—power consumption. To counter this, Virginia Tech mathematicians are leveraging algebraic geometry to target the inefficiencies of data centers....

Half a decade on from the start of the COVID-19 pandemic, a study by the University of Surrey highlights the significant impact of combined public health measures in reducing airborne viral transmission. High-quality face masks were shown to reduce transmission risk by ninefold, while doubling...

A collaborative study between the University of Helsinki, Aarhus University, the National Museum of Denmark and Seattle University examined the cognitive, cultural and historical significance of traditional string figures. The study explored whether certain string figures evolved independently in...

Nonlinear dynamical systems are systems that can undergo sudden shifts not due to changes in their state or stability, but in response to the rate at which external conditions or parameters change. These sudden shifts, known as noise-induced and rate-induced tipping, can make predicting how the...

We know a knight can move across the chessboard faster than the king, but exactly how much faster? Christian Táfula Santos, a doctoral student in UdeM's Department of Mathematics, has done the math and his proof has been published on the pre-print server arXiv....

A mathematician at Yonsei University, in Korea, claims to have solved the moving sofa problem. Jineon Baek has posted a 100+-page proof of the problem on the arXiv preprint server....
