Redefining physics to roll a ball vertically

Researchers from the University of Waterloo have achieved a feat previously thought to be impossible—getting a sphere to roll down a totally vertical surface without applying any external force.

Physicists determine how to cut onions with fewer tears

A team of physicists, biologists and engineers at Cornell University, in the U.S., has discovered some of the factors that lead to more or less spray when cutting onions and found a couple of ways to reduce the amount of ...
