The Nobel Prize in Physics was awarded this week to Arthur McDonald and Takaaki Kajita for their work with neutrinos.
The two were honored for their contributions to experiments demonstrating that subatomic particles called neutrinos change identities. The neutrinos transform themselves among three types: electron-type, muon-type and tau-type.
The transformation requires that neutrinos have mass, dispelling the long-held notion that they were massless. The Royal Swedish Academy of Sciences, which awards the Nobels, said the discovery “has changed our understanding of the innermost workings of matter.”
This is super impressive and, more importantly, gives us an excuse to re-run this awesome lolcat.
