Nobel Committee.

And I'm Steve Murski, and this is the Scientific American Podcast Science Talk for October 6th, 2015.

The Royal Swedish Academy of Sciences has decided to award the 2015 Nobel Prize in Physics to Takaki Kajeta and Arthur B. McDonald for the discovery of

neutrino oscillations, which shows that neutrinos have mass. Back in 2010, Arizona State

University physicist Lawrence Krauss wrote a column for a scientific American called Why I Love Neutrinos.

We happened to be at the same event that summer, so I spoke to him for a few minutes about neutrinos.
