For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope ...

In the early 1920s, physicists were first working out the mysteries of the quantum Universe. Particles sometimes behaved as waves, with indeterminate positions, momenta, energies, and other properties ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Take a look around you at everything on Earth. If you were to ...

They knew it was true, but now they've shown it: Scientists have demonstrated that the uncertainty principle, one of the most famous rules of quantum physics, operates in macroscopic objects visible ...

Quantum mechanics forbids us from measuring the universe. But we try with this principle. Quantum mechanics forbids us from measuring the universe beyond a certain level of precision. But that doesn’t ...

Researchers have proven that a fundamental law of physics applies in the quantum realm. The principle of least action dictates that objects will (unless interfered with) always move along the route ...
