How does one go about measuring the mass of an object? Mass is defined as the amount of matter an object contains. This is very different from weight, of course, as the mass of our object would remain ...

Neutrino mass measurement techniques represent a cornerstone of modern particle physics and cosmology. Given the elusive nature of neutrinos, experimental approaches have evolved to measure their ...

Scientists at the Institute of Modern Physics (lMP) of the Chinese Academy of Sciences (CAS) and their collaborators have demonstrated the effectiveness of an innovative nuclear mass measurement ...

A new measurement of the mass of the Milky Way galaxy suggests that Earth's galactic home is a bit lighter than many previous estimates suggested, but the scientists behind the new work say it's the ...

Most of the units we rely on are based on precision microscopic measurements—regular fluctuations in certain atoms define one second of time, for example. A major exception to this is the basic unit ...

The latest measurement of the mass of the W boson from the Tevatron experiments. The new combined result is twice as precise as the previous world average, and places limits on the mass of the Higgs ...

Scientists have achieved the most precise measurement to date of the mass of the W boson, one of nature's force-carrying particles. The measured value shows tension with the value expected based on ...
