The bizarre brilliance of bismuth
Schlieren flow visualization reveals the structure of a sonic boom
Tiny filament "flags" leave beautiful fluid wakes
Solids can flow like fluids, given the right circumstances
Using magnets, scientists re-create a space environment
Easily visible from space, this huge structure still puzzles scientists
The number of cracks in glass reveal the strength of projectile impacts
Ultrasound energizes gas bubbles, causing intense pressure and heat
Vibrating water reveals beautiful shapes
Simulations reveal a striking battle between two forces when lighter fluids flow above heavier ones.
When a Chladni plate vibrates patterns emerge in the sand. It’s not magic, or the hand of an invisible artist, but the vibrations themselves that cause the lines and patterns to emerge
When people think of waves they often look to the oceans, but waves can also be found high in the sky. In this picture Amsterdam Island in the Indian Ocean made waves in the clouds.
High power laser pulses create shock-waves and bubbles in plasma.
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.
A vibrating cornstarch solution appears to come alive and grow fingers. A dimple in the fluid created by a burst of air expands into a deep hole.
Puny tremors may be the real movers and shakers of the seismic world.
Quasicrystals are unusual metallic alloys whose atoms are arranged in orderly patterns that are not quite crystalline.
