Arthur B. McDonald

Arthur B. McDonald is a Canadian physicist renowned for his transformative work in neutrino physics, particularly through the Sudbury Neutrino Observatory. His research helped confirm that neutrinos, tiny subatomic particles created in nuclear reactions, can change types, which was pivotal in our understanding of their properties and the processes powering the sun. This breakthrough has significant implications for both nuclear astrophysics and high-energy astrophysics, enhancing our knowledge of stellar processes and the universe's fundamental characteristics. In 2015, McDonald was awarded the Nobel Prize in Physics for his contributions to this field.
