Koichiro Nishikawa, Breakthrough Prize In Fundamental Physics Laureate, Passes Away

We are greatly saddened to hear of the passing of Koichiro Nishikawa on November 28, 2018 at the age of 69. Nishikawa and colleagues won the 2016 Breakthrough Prize in Fundamental Physics for discovering that neutrinos “oscillate” between different states, the remarkable phenomenon by which the ghostlike particle transforms into different types of neutrino as it travels through space. This was a major milestone in the development of the Standard Model of fundamental particles, with significant implications for new physics yet to be discovered.

Our heartfelt condolences to his wife Natsuko, and his many colleagues and friends throughout the physics world.
