SMALLEST 'GUITAR STRING' TO WEIGH ATOMS Scientists hope that "playing" a tiny guitar string, the smallest ever created, will help unravel some of the secrets of the molecular world. The string, developed at Cornell University, US, is only 10 atoms across, a million times smaller than a normal guitar string. It is made from a carbon nanotube, formed from a sheet of carbon one atom thick and rolled into a cylinder. "As a scientist, the possibility that intrigues me the most is to be able to use it to, in essence, weigh things," explained Professor Paul McEwen, who helped pioneer the string. "If you imagine that you had a guitar string and you glued a little weight on to it. It would lower the frequency at which the guitar string vibrated, because the extra mass slows it down," he said. "The same thing happens here, but our string only has a few tens of thousands of atoms in it. So, just a few extra atoms, maybe even one, might shift the tone of the vibration enough for us to detect it." Little strings please little minds. A million times thinner than a guitar string? I knew a guy called Ron who used to roll fags that thin more...
