Each quark has a spin of 1/2, so you might simply think that so long as one spins in the opposite direction of the other two, you'd get the proton's spin. Up until the 1980s, that's exactly how ...

Taking quark-gluon plasma for a spin may un-break a fundamental symmetry Their rotations may tell us fundamental things about quantum chromodynamics. John Timmer - Aug 2, 2017 7:36 pm UTC.

The Quark claims to the world’s “highest performance classic spinning top in the world.” That means it’ll spin for a long, long time—up to 15 minutes a twirl, they say.

Sea quark surprise reveals deeper complexity in proton spin puzzle Date: March 14, 2019 Source: DOE/Brookhaven National Laboratory Summary: New data from the STAR experiment at the Relativistic ...

Physicists have been struggling to identify which of the nucleon’s other constituents contribute to nucleon spin and how much—a puzzle known as the proton-spin crisis (SN: 9/6/97, p. 158).

Neutron stars are so named because in the simplest of models they are made of neutrons. They form when the core of a large star collapses, and the weight of gravity causes atoms to collapse.
