In our previous voyages across the Dirac Sea, we have mostly followed great theorists and mathematicians. Dirac, Pauli, Fermi, and others who drew conclusions about particles no one had yet seen from equations, symmetries, and the internal logic of nature. The neutrino may be one of the finest examples of such physics: a particle first…
