Nobel Prize in physics goes to Takaaki Kajita and Arthur B. McDonald for work on neutrinos

(WASHINGTON POST)  Rachel Feltman — Their experiments challenged the standard model of physics.

The Nobel Prize in physics was awarded Tuesday to Takaaki Kajita of the University of Tokyo and Arthur B. McDonald of Queen’s University in Canada. Kajita and McDonald are honored for their contributions to observations on the oscillations of neutrinos, which show that neutrinos — previously thought to be massless — indeed have mass.

“This year’s prize is about changes in identity among some of the most abundant inhabitants in the universe,” the committee said during a news conference.

“It’s an absolutely fantastic choice. If anything, I think many physicists would say it’s long overdue,” Ray Jayawardhana, an astrophysicist at York University and author of “Neutrino Hunters,” told The Post.
