With 3D printed arms of fixed measurements, the depth reading from a set of digital calipers can be used to calculate the radius of a curve. Specialized tools that focus on one particular job tend to ...

Researchers have made a precise measurement of the size of the proton -- a crucial step towards solving a mystery that has preoccupied scientists around the world for the past decade. The world's ...

A discrepancy in the measured size of the “deuteron” increases the chance that something is amiss in our understanding of atoms. The same group that discovered a curious discrepancy in measurements of ...

Puzzling problem: Karsten Schuhmann (left) and Aldo Antognini of the Paul Scherrer Institute inspect the laser system that was used for the laser spectroscopy measurements on muonic deuterium.

Using the first new method in half a century for measuring the size of the proton via electron scattering, scientists have produced a new value for the proton's radius in a new experiment. Using the ...

TORONTO, September 5, 2019 - York University researchers have made a precise measurement of the size of the proton - a crucial step towards solving a mystery that has preoccupied scientists around the ...
