'Evil-genius' neutrino gun could unmask tiniest particles in the universe

Neutrinos are perhaps the most underrated particles known to humankind. Physicist, smart guy and smart aleck Wolfgang Pauli first proposed their existence in 1930 as a missing puzzle piece — certain nuclear reactions had more going in than they had coming out. Pauli reasoned that something tiny and invisible had to be involved — hence, the neutrino, which is kind of Italian for "little neutral one."
