Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

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 ...

An international team of physicists has measured the mass of a "strange" atomic nucleus with the aid of an innovative technique that is capable of significantly greater precision than that of previous ...

Atomic clocks are established as the most precise timekeepers created. Atomic clocks work by deploying lasers to measure the vibrations of atoms (electromagnetic signals). By atoms oscillating at a ...

July 21 (UPI) --A team of scientists from Germany and Japan have recorded the most precise measurement of a proton's mass. Researchers accomplished the feat by trapping a proton in a super sensitive ...

Time might feel like something we've got a pretty good handle on, but scientists are trying to find new ways to measure it ever more accurately. In recent tests run by the National Institute of ...

To measure the mass of neutrinos, scientists study radioactive decays in which they are emitted. An essential ingredient is the decay energy which corresponds to the mass difference between the mother ...
