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.
