Striking Notes of Progress on the World's Tiniest Guitar
Abstract:
It was weird enough when NASA's Chandra X-Ray Observatory recently came across a black hole, 250 million light years away, humming a bass note 57 octaves below middle C. Now scientists have found an accompanist to hold up the treble end. Cornell University physicists reported last week that they had used a laser beam to pluck the strings of an invisibly tiny silicon guitar just 10 millionths of a meter long. Each string of the instrument is about 50 nanometers wide - 100 atoms thick. The high-pitched sound of the nanoguitar twanged forth at 40 million cycles per second, putting it 17 octaves above what human ears take for music. (more on earlier article)
