AlHijjah 22, 1436, October 06, 2015, SPA -- Two physicists in Japan and Canada shared the 2015 Nobel Prize in Physics Tuesday for discoveries that subatomic particles known as neutrinos can change identities and have mass, offering new insights into the origin of the universe, dpa reported. Arthur B McDonald of Queen's University in Ontario and Takaaki Kajita of the University of Tokyo were cited for resolving "a neutrino puzzle that physicists had wrestled with for decades." "The discovery has changed our understanding of the innermost workings of matter and can prove crucial to our view of the universe," the Royal Swedish Academy of Sciences said. Neutrinos are the most numerous particles in the cosmos after photons, but before McDonald's and Kajita's discoveries remained "all but hidden," the academy said.
