(Phys.org)—An international team of researchers has developed a new way to measure the mass of a proton and found the particle to be approximately 30 billionths of a percent less than previously ...

Precision measurements in atomic and ion physics have become a cornerstone for testing the limits of our understanding of quantum electrodynamics (QED) and the Standard Model. By harnessing ...

Physicists in Australia have demonstrated the first “pumped” atom laser. Their achievement marks another step on the road to a continuously operating atom laser, which should enable high-precision ...

Input bias current is a usually overlooked amplifier parameter that can have a significant effect on an amplifier circuit’s output accuracy. Sometimes the effect is small enough to be ignored, but ...

Osaka Metropolitan University researchers present a straightforward method for predicting the average measurement precision of fringe projection photogrammetry in a target area. The proposed method ...

A new result from the Q-weak experiment provides a precision test of the weak force, one of four fundamental forces in nature. The proton's weak charge was found to be QWp=0.0719±0.0045, in excellent ...

SAN JOSE, Calif., Nov. 19, 2025 (GLOBE NEWSWIRE) -- zSpace, Inc. (NASDAQ: ZSPC), a global leader in immersive augmented reality (AR) learning solutions for education, today announced the release of ...

“Classical Cepheids” are a type of pulsating star that rhythmically brightens and dims over time. These pulsations help astronomers measure vast distances across space, which makes Cepheids crucial ...
