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.

Tête de Moine, a semi-hard Swiss cheese that often finds its way onto charcuterie boards and salads, not only brings a rich, nutty and creamy flavor, but also adds a dramatic flare to the presentation. Instead of slicing, ...
Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The discovery will allow researchers ...
