Mixing different beads delineates coherent structures, providing insight into how grains mix.
Simulations indicate that hydrogen bond density is higher on the surface of titanium dioxide than on tin dioxide, but the hydrogen bonds are found to be stronger on tin dioxide than titanium dioxide.
When researchers tried packing billiard-ball-like spheres in a number of ways, the most chaotic ones were consistently the most symmetrical.

Oil is slick but did you know it can also bounce?
It might seem intuitively obvious that a layer of dense liquid resting on a less dense liquid is an unstable situation. What isn't as obvious is the complex way that liquids arranged in this manner and tend to move.
Researchers have been frustrated in their attempts to confirm the long-standing theory that describes how dyes mix in turbulent liquids.
The erratic, swirling fluid motion known as turbulence increases wind resistance, and airplane manufacturers go to great lengths to eliminate rough surfaces that promote it.
Sparks branch for the same reason that coral reefs and snowflakes do, according to new computer simulations.
Windblown dunes can engulf houses, roads, and airfields, but researchers have had a hard time studying them under controlled conditions.
