Speedy Spinning Spheres! Using spheres, cylinders, and straws, the Crew and Dr. Rob learn about inertia, velocity, and conservation of energy due to angular momentum. STEM Challenge: Angular Momentum ...

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 ...

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 ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

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 ...

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 ...

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 ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

In the beam of light emitted by a laser pointer, photons travel predominantly along one direction and the beam is therefore said to be collimated. The electric field carried by these photons is ...

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 ...
