Kazuhiko Nishijima of the University of Illinois recently received the Japan Academy Award for his contributions to theoretical physics, particularly for his work in strangeness theory. In 1953, Dr. Nishijima, then in Japan, and Murray Gell‐Mann in the US introduced into strange‐particle physics the hypothesis of charge independence by assuming the generality of the relation between charge and the third component of isotopic spin that had already been observed for pions and nucleons. This required the introduction of another quantum number, S, the “strangeness” number.
