Sixty Symbols

DU — Fri, 26 Jun 2009 06:24:31 -0800

What Periodic Videos did for chemistry, Sixty Symbols is doing for physics and engineering. Some behind the scenes action and general scienciness. Some of the "symbols" are a little iffy and many are just jumping off points for a cool science demo/discussion, but that doesn't change the high quality of the material.

Incredibots. Make crazy machines! Solve puzzles! Share with your friends! And that's just the beta. Similarly Click "Play" to see my hastily assembled machine in action. Click "Stop Simulation" to stop it. Click on "Main Menu" to do your own thing.

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

MetaMonkey — Wed, 25 Jan 2006 07:41:47 -0800

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.

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.
