The dimensions of a physical quantity are the powers or exponents to which the base quantities are raised to represent that quantity. Note: Using the square brackets [ ] round a quantity means that we ...

Scientists reveal unprecedented ability to "side-step" the Heisenberg Uncertainty Principle by simultaneously measuring ...

He added that the team learned the behaviour of their system in 15 minutes. A comparable classical method would take around 20 million years. The experiment took place in the basement labs at DTU ...

Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

Electrons are still almost perfectly round, a new measurement shows. A more squished shape could hint at the presence of never-before-seen subatomic particles, so the result stymies the search for new ...

New measurements of a subatomic particle provide the strongest hint yet that the leading theory of quantum physics that explains our universe may be missing a fundamental element, scientists say. The ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. Probably no technology from the Star Trek universe is more fervently ...
