Mr. Speaker, I rise to salute the fantastic achievements of Dr. Arthur McDonald, the co-winner of the 2015 Nobel Prize in physics. Dr. McDonald, a professor at Queen's University, led a global team of over 270 researchers from 13 international institutions to the discovery that neutrinos can change identities, thereby confirming that particles have mass. This discovery upset the standard model of physics and changed our understanding of how the universe works.
The team conducted these experiments at the Sudbury Neutrino Observatory, or SNOLAB, in the Creighton mine, located two kilometres underground in my riding of Sudbury. The lab is the deepest clean room facility in the world, allowing scientists to study the particles free from cosmic radiation constantly bombarding the earth's surface.
Residents of Sudbury and all Canadians have reason to be proud of Dr. McDonald's scientific achievements.
I invite all members to join me in conveying our deepest congratulations to the 2015 Nobel Prize in physics winner, Dr. McDonald, and his team of collaborators.
