Paper types ranked by likelihood of paper cuts
Via testing with a skin stand-in, a trio of physicists at Technical University of Denmark has ranked the types of paper that are the most likely to cause a paper cut. In an article published in Physical Review E, Sif Fink ...
Using machine learning to speed up simulations of irregularly shaped particles
Simulating particles is a relatively simple task when those particles are spherical. In the real world, however, most particles are not perfect spheres, but take on irregular and varying shapes and sizes. Simulating these ...

How do curve balls, cutters, sinkers and sweepers work?
It's a cliché that "baseball is a game of inches," but for hitters and pitchers, it's more a game of millimeters. If the bat hits the ball a fraction of an inch too low or too high, the result is a popup or weak ground ball ...
