Yukawa, Hideki (1907–1981)
Japanese physicist who postulated the meson
as the agent binding the atomic nucleus
together, i.e., the quantum of the strong
force. In fact, the mu-meson, or muon,
discovered shortly afterwards (in 1936) by Carl Anderson,
does not fulfill this role and Yukawa had to wait until C. F. Powell (1903–69),
at Bristol University, discovered the pi-meson, or pion,
in 1947 for vindication of his theory. Yukawa received the 1949 Nobel Prize
in Physics. Related category
