Granular model explains unusual behavior in sand
From a mechanical perspective, granular materials are stuck between a rock and a fluid place, with behavior resembling neither a solid nor a liquid. Think of sand through an hourglass: As grains funnel through, ...

Solving the future with abstract algebra
Ask people what they know about the frontiers of mathematics research, and the response is usually some variation on: "What is there to research about math?"
First mathematical analysis of gun policy tradeoff emphasizes need for more data
Stock market models help researchers predict animal behavior
In an unexpected mashup of financial and mechanical engineering, researchers have discovered that the same modeling used to forecast fluctuations in the stock market can be used to predict aspects of animal ...
Is mathematics an effective way to describe the world?
Encryption is less secure than we thought
Information theory—the discipline that gave us digital communication and data compression—also put cryptography on a secure mathematical foundation. Since 1948, when the paper that created information theory first appear ...
Mathematicians calculate that there are 177,147 ways to knot a tie
Fluid mechanics suggests alternative to quantum orthodoxy
The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum ...
Study using OpenStreetMap and mathematics reveals there are only four unique city topologies
Proving uncertainty: First rigorous formulation supporting Heisenberg's famous 1927 principle
Nearly 90 years after Werner Heisenberg pioneered his uncertainty principle, a group of researchers from three countries has provided substantial new insight into this fundamental tenet of quantum physics ...
