Mr. Speaker, I rise today to recognize Queen's University professor Arthur McDonald, who now shares the Nobel Prize in Physics with Takaaki Kajita from Japan, for their discovery of neutrino oscillations, which changes our understanding of the innermost workings of matter. The discovery concluded that neutrinos, which for a long time were considered massless, must have some mass, however small.
Experiments continue worldwide to capture neutrinos and examine their properties. These new discoveries are expected to change our understanding of the history, the structure, and the future of the universe.
Dr. McDonald's research yielded a historic discovery in particle physics at the Sudbury Neutrino Observatory. His innovative vision has made Canada a world leader in the field of particle astrophysics and has paved the way for international collaborations.
Congratulations to Dr. McDonald.
