Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

Imagine a satellite, floating in space. How would you measure its voltage? Yes, it probably has a non-zero voltage, a consequence of geospatial electric fields and ion and electron currents. The ...

Researchers in Europe have developed a technique for obtaining accurate laser-based measurements of objects hidden behind complex scattering structures. They say that their mathematical formula, which ...

The major goal of quantum metrology has been to create highly entangled states with improved sensitivity per resource than classical approaches. However, collective observations are required to reach ...

Many creatures in nature, including butterflies, newts and mole rats, use Earth's inherent magnetic field lines and field intensity variations to determine their geographical position. The spatial ...

The novel LIDAR ("light detection and ranging") system could have applications from precision manufacturing lines on Earth to maintaining networks of satellites in perfect formation, creating a giant ...

Forget hunting for a tape measure or a protractor. Use your Android phone camera and sensors to handle different types of measurements easily.

Astronomers have directly measured a blazing-bright object on the opposite side of the Milky Way, almost doubling the record for the most distant object measured in our own galaxy. The researchers ...

A January 2026 Earth–Sun alignment allows measurements of the opposition surge from interstellar object 3I/ATLAS using ...

You can measure objects on an iPhone using Apple's Measure app. The app is free and works with specific versions of the iPhone, iPad, and iPod. You may be able to ...

Gravity may feel like one of the most familiar forces, but it’s actually among those we understand least. We know our current model of gravity is inconsistent with quantum mechanics. It also fails to ...
