by Sydney native Art McDonald is in Stockholm, Sweden this morning to officially receive his Nobel Prize for physics.
In October the Royal Swedish Academy announced that MacDonald will share the prize with Japanese scientist Takaaki Kajita for their work with neutrinos.
Neutrinos are subatomic particles with almost no mass that rarely interact with anything else.
The Academy of Sciences says that McDonald and Kajita have made key contributions to experiments showing that neutrinos change identities.
It also says that the discovery has changed our understanding of the innermost workings of matter and can prove crucial to our view of the universe.
McDonald is a retired professor with Queen’s University in Kingston, Ontario and is also the director of the Sudbury Neutrino Observatory.
He’ll split about 1.3 million dollars Canadian in prize money.
Each winner also gets a diploma and a gold medal at the prize ceremony.
