Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals. Subscribe to our newsletter for the latest ...

Generations of scientists have tried to explain how the solar system began. None of the explanations is wholly adequate. The trouble is that the solar system is not a haphazard collection of planets ...
