What’s So Funny About Neutrinos?
How Nature’s Elusive Lightweight Particles Have Been the Targets of Humor for 90 Years

Neutrinos arrived as the neat solution to a vexing problem in particle physics. In the radioactive process called beta decay, in which atomic nuclei transform themselves by emitting beta particles (energetic electrons), researchers discovered that a measure of energy and momentum (mass times velocity) was lost. On the…
