The ALPHA collaboration at CERN reports an important milestone on the way to measuring the properties of antimatter atoms. This follows news reported in June last year that the collaboration had ...

Nucleons, which include protons and neutrons, are the composite particles that make up atomic nuclei. While these particles have been widely studied in the past, their internal structure has not yet ...

Breaking up: a new measurement of the hydrogen dissociation energy disagrees with theory. (Courtesy: iStock/FrankRamspott) The most precise experimental value for the dissociation energy of molecular ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

The number-one job of a marketer is to invest budget wisely to drive sales. That inherently requires accurately measuring the performance of that spending. Yet most advertisers still rely on flawed ...

On Jan. 31, 1958, Explorer 1 became the first satellite launched by the United States. Its primary science instrument, a ...

In many quantum measurement experiments and thought experiments, measurement results appear that do not seem to have classic explanations. As example: In quantum particle spin experiments, entangled ...

This film demonstrates the measurement of the speed of light in both air and water using experimental setups. The first experiment involves measuring the time it takes for light to travel a known ...
