We interrupt your regularly scheduled panic over Verizon, the National Security Agency, and PRISM for a few minutes of magnificent science-art.
Using just a tone generator, a speaker, and a metal plate, YouTube artist Brusspup shows us how certain frequencies can vibrate sand into wildly intricate patterns. The patterns increase in complexity as the frequency increases in pitch. Of course, it all has to do with math, specifically Chladni’s law. The unedited version lets you listen to the actual frequencies that make each pattern, but you’ll want to be sure to lower your volume. Quartz Crusher Supplier
