Arthur B. McDonald

McDonald's Nobel Prize is the pinnacle of a career marked by groundbreaking experimental physics. The SNO experiment not only solved the solar neutrino problem but also demonstrated that neutrinos have mass, a discovery that has profound implications for particle physics and cosmology. His leadership of the collaboration is often cited as a model of international scientific cooperation.Beyond the Nobel, McDonald has received Canada's highest civilian honors, including the Order of Canada and the Order of Ontario. He is a fellow of several prestigious societies, including the Royal Society of Canada and the Royal Society of London. His legacy continues through the institute that bears his name, which supports astroparticle physics research across Canada.
