Executive summary: Detected cosmic neutrinos

Masatoshi Koshiba has said that while attending the University of Tokyo he was more interested in studying German art than science, until the teacher of his required class in physics told him he was not smart enough to master the topic. "That made me furious", Koshiba later recalled, "so I took the entrance exam for the physics department."

In a long career in Japan and America, Koshiba became an expert on neutrinos, the ghostly and omnipresent particles which result from nuclear decay reactions. In 1987 he confirmed Raymond Davis, Jr's experiments that showed, to the bafflement of physicists, that the number of solar neutrinos present in the Earth's atmosphere is actually about one-third of what scientists had previously expected. In his best known work, Koshiba explained that the number of neutrinos had been depleted because neutrinos can change characteristics in transit. He was awarded the highest honor in science, the Nobel Prize, in 2002.
