Playing Nanoguitars

A nanoguitar, devised at Cornell years ago, has been "played" for the first time by shooting laser light at the silicon "strings." A newer version of the guitar, shown above, twangs at a frequency of 40 megahertz, some 17 octaves (or a factor of 130,000) higher than a normal guitar.
