1930 in science

A neutrino ( ; denoted by the Greek letter Nu (letter)|) is an elementary particle that interacts via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero. The rest mass of the neutrino is much smaller than that of the other known elementary particles (excluding massless particles).

The venture took place from July 1930 until August 1931, and established three Arctic stations on the same parallel.
