CANADIAN INDUSTRY ONLINE - DECEMBER 2015Art McDonaldLAST YEAR WAS big year for science in Canada. Much to the delight of the national scienti c com-munity, Professor Arthur B. McDonald shared a Nobel Prize win with Japan’s Takaaki Kajita, and the recognition was announced in October 2015.The win came 13 years after Mc- Donald and his tenacious team at SNO- LAB in Sudbury, Ontario, published a ground-breaking paper on neutri- nos, proving through their research that neutrinos have mass (McDonald is a Director at SNOLAB). McDonald and his SNOLAB team worked on ex- periments that helped to demonstrate that subatomic particles called neutri- nos change identities, and this change requires that those neutrinos are not massless, as previously believed.This breakthrough science was a huge step forward for physics research, but also for Canada on a bigger scale. McDonald, a native to Cape Breton, Nova Scotia, has been a professor (and now is professor emeritus) at Queen’s University since 1989, and has been part of experiments that have changed the way scientists think about mass around the world. This is no small feat, and with his colleagues in Sudbury, McDonald has drawn international ac- colades for his work.When CIO spoke with McDonald, he was very adamant that his wholeteam at SNOLAB, the community of Sudbury, and Canadian industry on the whole be recognized for the important scienti c work that has been done and ultimately led to the Nobel win.One of the most remarkable parts of the win, and McDonald’s research, is that it was done at SNOLAB, un- derground, with a detector 10 storiesPhoto credit: Bernard Clark.
