The 2015 Nobel Prize in Physics is awarded to Takaaki Kajita at The University of Tokyo and Arthur B. McDonald at Queen’s University “for the discovery of neutrino oscillations, which shows that neutrinos have mass”.
Takaaki Kajita is a Japanese physicist, known for neutrino experiments.
Arthur Bruce McDonald, is a Canadian physicist and the Director of Sudbury Neutrino Observatory Institute.
They are awarded for their key contributions to the experiments which demonstrated that neutrinos change identities. This metamorphosis requires that neutrinos have mass. The discovery has changed our understanding of the innermost workings of matter and can prove crucial to our view of the universe.
The discovery rewarded with this year’s Nobel Prize in Physics have yielded crucial insights into the all but hidden world of neutrinos. After photons, the particles of light, neutrinos are the most numerous in the entire cosmos. The Earth is constantly bombarded by them.
Many neutrinos are created in reactions between cosmic radiation and the Earth’s atmosphere. Others are produced in nuclear reactions inside the Sun. Thousands of billions of neutrinos are streaming through our bodies each second.
