Physics is a natural science that, compared to others, is less popular among the general population, both adults & children. However, awareness of the presence of physics in every corner of our ...

The roles of energy, momentum and orbital angular momentum conservation in high-harmonic generation were studied in the past. Here, we explore the role of spin angular momentum in high-harmonic ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...

Schematic of a single photon with zero angular momentum (green) splitting into two photons (red) with either zero or opposite angular momenta (sketched through the spatially varying color), which adds ...

When a magnetic material like nickel is zapped with an incredibly short laser pulse, it loses its magnetism almost instantly within femtoseconds, or a millionth of a billionth of a second. But physics ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...

BAKERSFIELD, Calif. (KERO) — If you've ever found yourself in an office chair you know it can be tough to resist the urge to spin around! In this edition of Science Sunday we'll give you an excuse to ...

Students learn to define, give the MKS units for, and calculate momentum. Momentum: Students learn to define, give the MKS units for, and calculate momentum and to use the impulse equation to explain ...

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 ...
