At first glance, a roulette table looks like a jumble of numbers and a randomly hopping little white ball. But with a better understanding of physics and some general knowledge of the starting conditions, it may be possible ...

Friction, the force that slows down objects as they slide across a surface, can save lives when car brakes are slammed. Yet despite its obvious importance, no one knows for sure how friction works at the level of atoms and ...

(Phys.org)—When nanosized pieces of graphite slide against each other, there can be virtually no friction between them. For many years, superlow friction, or "superlubricity," was known to exist only on the nanoscale. Then ...
(PhysOrg.com) -- For the first time, researchers have measured a long-theorized force that operates at distances so tiny they’re measured in billionths of a meter, which may have important applications in nanotechnology ...

(Phys.org)—A team of researchers working at Argonne National Laboratory, in Illinois, has found a way to dramatically reduce friction between two macroscopic scale surfaces—to near zero. In their paper published in the ...
The answer lies in a film of water that is generated by friction, one that is far thinner than expected and much more viscous than usual water through its resemblance to the "snow cones" of crushed ice we drink during the ...
