Two galleries of fluid motion - one from the journal Physics of Fluids, and one from MIT. The MIT gallery shows some common everyday fluids in unexpected lights. The PoF gallery (which is quite extensive, check out the 85-09 archives) mostly concerns itself with more esoteric interests. Some of the results presented have a stark beauty and some are riotously colourful. I personally love the results that look at turbulence and transition. Also, some visualisations from the past ten or so years are presented as video! (PDFs, Quicktime)

I Am Trying to Believe. Well, maybe not. (Previously: Best, shortest review of a NIN cd, ever.)

Order from chaos! Fill a cylindrical bucket with water and make it so the bottom can spin. At certain speeds, stable regular polygonal shapes will spontaneously form at the turbulent surface of the water. See the video. [2.6MB avi] [via last week's PRL]

Vortical interfaces between immiscible fluids - a slow-motion video of various vortexes of Newtonian and non-Newtonian fluids, set to Soundgarden's Black Hole Sun, with explanatory captions. Pleasing to the eyes.

Gallery of Fluid Dynamics. 'One of the most attractive features of fluid mechanics is the beauty of the flows one encounters. Whether one is observing vortex streets, the potential flow around an airfoil or body, shock refraction or diffraction, or waves breaking on a beach the aesthetic appeal of fluid mechanics is impossible to deny.

The Pitch Drop Experiment. Everyone should know by now that 'glass is a supercooled liquid' is an urban legend. But there are true liquids that appear solid at room temperature. Pitch, a petroleum derivative, is one of them. The Blair Pitch Pro Pitch Drop Experiment, begun in 1927, drips pitch out of a funnel, at roughly one drop every ten years. It has a webcam [RealPlayer req.], with a short canned loop of audio explaining the experiment's origins. I tell you, I'm on the edge of my seat watching this thing!
