Background

Kosiba studied at the University of Tokyo. After graduation in 1951, he enrolled in graduate school and moved in 1953 to the University of Rochester in the US. In 1955 Kosiba receiving a doctorate for work on superhigh phenomena in cosmic rays.

In March 1970, Kosiba became a professor at Tokyo University.

In the 1950s and 1960s Kosiba involved high-energy cosmic radiation and related phenomena in the upper atmosphere. These studies led him in 1970 to the physics of muons and neutrinos, as well as the physics of elementary particles. After participating in the JADE - a joint German-Japanese project in the DESY accelerator in Hamburg, he constructed Kamiokande detector for registration predicted by the theory of proton decay. Since proton decay registration failed, he rebuilt a neutrino detector in the detector and was able to register a cosmic neutrino in the process of the explosion of the supernova 1987A failed to register 12 neutrinos, 9 of which are in the first 2 seconds. This was the first direct experimental proof of theories about the processes occurring during the collapse of stars, in particular the theory of neutrino cooling.

In 2002, he was awarded the Nobel Prize in Physics. Together with Raymond Davis, he received half of the prize, the second half was Riccardo Giacconi.
