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.

Scientists Build World’s Most Sensitive Scale, Can Weigh Single Proton

Humor : Geekosystem (3 years ago)

Unlike your typical spring-powered scale, high-precision scales used to weigh the smallest materials use carbon nanotubes which vibrate at different frequencies depending on the mass on them. However, a group of scientists at the Ca... Read Post

World's Most Sensitive Scale Can Weigh A Single Proton

Humor : Geekologie (3 years ago)

The world's most sensitive scale, which functions by measuring the vibration frequency of carbon nanotubes when a mass is rested upon them, can now measure the mass of a single proton. pretty lightweight. Like probably les... Read Post

The most sensitive weight scale ever can weigh individual protons [Mad Science]

Genres / Sci Fi : io9 (3 years ago)

A new subatomic weight scale can measure masses as tiny as one yoctogram. Less than the mass of a proton, a yoctogram is equivalent to a billionth of a billionth of a millionth of a gram. More » Read Post
