School of Rock: The Physics of Waves on Guitar Strings
The rubber band example does indeed have two nodes—they are at the ends of the rubber band where your fingers hold it. We only have half a wavelength in the standing wave, but there is indeed a relationship between the length of the rubber band and the size of the wavelength. Guitar Strings It’s time…
Giant polygon rock patterns may be buried deep below Mars’ surface
Enormous polygon patterns in rock lie dozens of meters below Mars’ surface, ground-penetrating radar data suggest. Similar patterns develop on the surface in Earth’s polar regions when icy sediments cool and contract. A comparable process long ago may have created the shapes on Mars, found near the planet’s dry equator, researchers report November 23 in…
Can Rock Dust Soak Up Carbon Emissions? A Giant Experiment Is Set to Find Out
Mary Yap has spent the last year and a half trying to get farmers to fall in love with basalt. The volcanic rock is chock full of nutrients, captured as its crystal structure forms from cooling magma, and can make soil less acidic. In that way it’s like limestone, which farmers often use to improve…
