Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
An unstable subatomic particle of the same class as an electron (a lepton), but with a mass around 200 times greater. Muons make up much of the cosmic radiation reaching the earth's surface.→ mu-meson
- ‘Comsic rays are very high energy particles which strike the Earth's atmosphere and produce spectacular showers of billions of electrons, muons, and other particles.’
- ‘The number of times that an antimuon emits a positron in the same direction as its polarization was found to be equal to the number of times that a muon emits an electron in the opposite direction.’
- ‘Incidently, before the quark theory was invented to understand the properties of elementary particles the term ‘meson’ was also applies to muons - which are not made up of quarks but are fundamental point particles like the electron.’
- ‘The proton and the neutron are baryons; the electron, the muon, and the neutrino are leptons; whilst the pions are mesons.’
- ‘These objects also produce high-energy massive particles such as electrons, muons, protons and anti-protons.’
1950s: contraction of mu-meson; the particle, however, is no longer regarded as a meson.
