Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...

Neutron scattering has emerged as a mainstream scientific endeavour over the last 20–30 years. Having previously been the preserve of researchers studying superconductivity and magnetism, neutron ...

The wavefunction for indistinguishable fermions is anti-symmetric under particle exchange, which directly leads to the Pauli exclusion principle, and hence underlies the structure of atoms and the ...

A long-standing physics mystery has been solved with the discovery of emergent photon-like behavior inside a strange quantum ...
