there is no soundtrack

Finite time blowup for an averaged three-dimensional Navier-Stokes equation - "[Terence Tao] has shown that in an alternative abstract universe closely related to the one described by the Navier-Stokes equations, it is possible for a body of fluid to form a sort of computer, which can build a self-replicating fluid robot that, like the Cat in the Hat, keeps transferring its energy to smaller and smaller copies of itself until the fluid 'blows up.'

Watching Paint Dry

Prof Lakshminarayanan Mahadevan looks at the physics of wrinkles, creases and folds - from the small to the very large (video demos), feeds his venus flytrap, then rides on his magic carpet.

Ripple Tank Simulation

Ripple Tank Simulation is a delightful, mesmeric java applet simulation of a ripple tank. It demonstrates two dimensional wave phenomena such as interference, diffraction, refraction, resonance, phased arrays, and the Doppler effect (do try the 3D view). From Paul Falstad's fantastic collection of Math, Physics and Engineering Applets.

wasting time...

The museum of unworkable devices... Gravity -- it's not just a good idea, it's the law. Perpetual motion, and other wonderful things.

There's been a lot of talk of late about signal-to-noise ratios here on MeFi (er, Ashcroft who?...). Generally, we think of noise as something that always degrades the quality of a signal. Sometimes, however, the opposite can be the case. Here's a neat little demonstration of a non-linear system in which noise can be used to amplify a signal that would otherwise be too be faint to detect any other way. It exploits a phenomenon known as Stochastic Resonance.
