It isn't a fancy Rorschach blot or a computed tomography scan of the intestines. Instead, the image “Chaotic Mixing in Viscous Fluids” depicts the chaotic mixing caused by stirring a vat of glycerin and fluorescent dye. It's one example of liquid artistry on display at this gallery* from the journal Physics of Fluids. Showcased here are winning entries from the American Physical Society's annual exhibition of videos and photos. You can admire shots from as far back as 1985, although you'll need a journal subscription to see the newest entries. This fluid dynamics collection from applied mathematician John Bush of the Massachusetts Institute of Technology uses a strobe lamp and other tricks to reveal unexpected and striking patterns, such as the trail of turbulence created by a water strider.
