For surfers, it's not enough just to wait for the right wave: they still have to know how to catch it. As it turns out, one challenge faced by surfers also applies to protons. An experiment recently ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...

HEISENBERG has discussed the hypothesis that the nucleus of an atom is composed of neutrons and protons only, the neutron being regarded as a fundamental entity and not as a combination of an electron ...

Known as “islands of inversion,” these odd regions are found among a sea of normal nuclei. Now, a new island may have been spotted in surprising circumstances.

Standard atomic weights, those numbers emblazoned under the elements on the periodic table, were once thought of as unchanging constants of nature. But researchers have tweaked the atomic weights of ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

Are the fundamental constants really constant? Recent investigations have shown that one essential fundamental constant -- namely the mass ratio of protons to electrons -- can have changed only by a ...

Physicists studying atomic spin surprised themselves by discovering that spinning protons bizarrely change direction when they crash into larger particles, like the nuclei of gold atoms. On a pool ...

If you've learned all the elements from actinium to zirconium, it's time to head back to the periodic table, where there's a new, extremely heavy element in town. In case you forgot your high school ...
