The Most Sensitive Scale Ever Can Measure The Mass of One Proton

The smallest named unit in the metric system is the yoctogram, equal to 0.000000000000000000000001 grams. (Yes, that’s 24 zeros.) For a scale that can measure differences in mass as small as a yoctogram, which is on the order of the mass of a proton, physicists writing in Nature Nanotechnology turned to the wunderkind of nanotechnology: carbon nanotubes. Carbon nanotubes are tiny—though not quite yoctogram-tiny—sheets of carbon rolled up into a cylinder.
