How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA ...

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 ...

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

Orbital angular momentum has the potential to transfer, manipulate and store information. They are made from the orbital angular momentum of electrons orbiting their atomic nucleus – and the study of ...

A study examines angular momentum constraints on the formation and orbital evolution of the Moon. Proposed scenarios for the Moon's formation typically involve a giant impact that would have left the ...

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 ...

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 ...

Every dazzling jump on the ice—like Yuzuru Hanyu's quadruple Lutz at the 2017 Grand Prix of Figure Skating in Moscow, Russia—requires a mastery of balance, rotational speed and angular momentum. Aflo ...

Twisted light: self-torque could be used to manipulate molecules. (Courtesy: iStock/VikaSuh) Physicists in Spain and the US have shown that the orbital angular momentum, or twistedness, of light can ...
