Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A subatomic particle that is intermediate in mass between an electron and a proton and transmits the strong interaction that binds nucleons together in the atomic nucleus.
- ‘Prior to this era, protons and neutrons and mesons don't exist, there is just a hot soup of quarks and gluons in their place.’
- ‘Most particles are either mesons, which contain a quark and an antiquark, or baryons, which comprise three quarks or three antiquarks.’
- ‘Quarks are permanently bound together into protons, neutrons and mesons.’
- ‘The simplest hadrons are therefore mesons made from a quark and antiquark pair (where the difference is zero), and baryons made of three quarks (where the difference is three).’
- ‘Composite bosons, or mesons, help to hold atoms together.’
- ‘They proposed that particles like the proton, the neutron, and the mesons, which feel the strong nuclear force, are not elementary particles at all, but possess internal constituents.’
- ‘Each of the new versions was a little bit different, and it was always hoped that one of the new versions would look exactly like protons, neutrons, mesons, and so forth.’
- ‘The existence of quarks inside the mesons and baryons had to be deduced mathematically because free quarks have never been observed by particle physics.’
- ‘Kaons and pions are examples of particles known as mesons, which contain a quark and an antiquark.’
- ‘There is the almost impossibly small world of gluons and mesons and quarks, but also the infinitely vast cosmological field strewn with uncountable galaxies.’
- ‘If there were no difference between matter and antimatter, both the B mesons and the anti-B mesons would exhibit exactly the same pattern of decays.’
- ‘A particle physicist is not expected to be impartial about the quarks and mesons spinning about in his plasma stew, but he is expected to produce evidence and findings that are honest and reproducible.’
- ‘At that time, researchers were using cosmic radiation as a source of high-energy particles to study nuclear reactions and properties of the newly discovered p and m mesons.’
- ‘This includes mesons like pions, gauge particles like photons and gluons, the hypothesized Higgs scalar, etc.’
- ‘The researchers studied the production of neutral mesons when a neutron is captured by a proton in a hydrogen target to form a deuteron.’
- ‘Gell-Mann distinguished baryons from mesons, the other hadron subclassification, by the number of quarks constituting their make-up.’
- ‘Must be because our mesons and quarks and stuff are linked, like the way you can see me even though I'm not really here.’
- ‘Electrons and positrons collide at unequal energies inside a sophisticated, 1,200-ton particle detector called BABAR, creating millions of short-lived subatomic particles know as B mesons.’
- ‘He suggested that the strong nuclear force results from the exchange of a particle between the neutrons and the protons; he named that exchange particle a meson.’
- ‘Protons and neutrons sense each other via exchange particles (called pi mesons, or pions) with each other in the nucleus.’
