This image reveals the intricate wake structure left behind two cylinders rotating in a fluid.
Simulations reveal a striking battle between two forces when lighter fluids flow above heavier ones.
A time lapse image of a developing slime mold network. By watching this growth, physicists hope to better understand the analogous development of transportation networks.
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.
Molecular diffusion and chemical reactions can result in a chemical wave front.
Experimental evidence suggests that the human genome may bundle into these unknotted fractal globules.
High frequency trading computers can help make investors millions, but where in the world would be the best place for these computers to be located? Physics could help explain how to make your millions.
Inside cells there is a long code that holds all of an organism’s hereditary information, but how does that long code fit in that tiny space?
What do brains and bread have in common? Physicists looking for patterns explain.
New simulations show that reducing the number of spare DNA genes in the microbe E. coli can actually increase the bacteria’s chances of survival.
Ghost of discharged capacitor found haunting a glass of water! What could be more scary than that? Try a hot ball of electric plasma.
This crown is formed by the splash and droplets of a 2 mm drop of red dye impacting on a thin layer of milk.
A cylinder twisting back and forth in water, produces a "centrifugal instability," as shown by fluorescent dye. This fluid pattern will not only help scientists better understand ocean dynamics, but it is also aesthetically beautiful.
Red and green dye reveals the turbulent fluid flows from the magneto hydro dynamic propulsion device.
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.
The symbolic beauty of a flag flying high in the wind is simple to understand.
From bonfires to match sticks, flames usually have simple, predictable shapes.
When the faucet drips, most people call the plumber or get out their tools, but some physicists are content to study the phenomenon instead.
The crystallization process that turns a liquid to a solid is brutally competitive, according to an analysis of experiments performed on the Space Shuttle.
If you fill a barrel part-way with red beads, add some green beads, and then roll it around the room a bit, will your beads blend?
