Phonology — the branch of linguistics concerned with the systematic organization of speech sounds in natural languages — studies not the physical sounds themselves (that is phonetics) but the abstract cognitive system by
Q_4_04 — Neutrino Astronomy and Neutrino Mass
Neutrinos — nearly massless, electrically neutral leptons that interact only via the weak nuclear force and gravity — are among the most abundant particles in the universe (~330/cm³ relic neutrinos from the Big Bang) yet
