neutrino — noun

1. one of the smallest known types of particle in physics. Neutrinos have no electr
one of the smallest known types of particle in physics. Neutrinos have no electric charge and an extremely tiny amount of mass. They are produced by nuclear reactions—for example inside the Sun and other stars—and they pass through ordinary matter with almost no interaction, making them very difficult to detect.
Neutrinos from the Sun pass through your body every second without you feeling anything.
pass through [body/surface] without [noticeable effect] — particle behaviour pattern
Scientists built a huge detector in an old mine to study neutrinos coming from space.
detector + built in [location] + to study [source] — scientific setup pattern
A single neutrino can travel through the whole Earth as if the planet were empty.
Henrik designed a new experiment to catch neutrinos from exploding stars far away.
Walid explained to his physics class that neutrinos have almost no mass and no charge.
- elementary particle
a broader category; neutrinos are one type of elementary particle, along with electrons and quarks
- lepton
a more technical physics term; neutrinos belong to the lepton family of particles, which also includes electrons and muons
文法句型
a neutrino / neutrinos
[number] neutrinos
用法筆記
The plural form 'neutrinos' is far more common than the singular because the particle is typically discussed as a collective type. The word appears most often in scientific and popular science writing rather than in everyday conversation.
