First Japanese Physicist to Win the Nobel Prize in Physics Yukawa, Hideki 1907-81 . 1963 By N. Kemmer, F.R.S. In 1935, a Japanese scientist, Hideki Yukawa was given a successful theory of nuclear forces, known as Yukawa theory or Meson theory, and tried to explain how nuclear forces hold a nucleus. From theoretical considerations, in 1934 Hideki Yukawa predicted the existence and the approximate mass of the "meson" as the carrier of the nuclear force that holds atomic nuclei together. Economics Text book - 11 in Hindi Hindi Textbook. However Democritus made the false claim that atoms were indestructible which was proven wrong with the development of the atomic bomb (nuclear power), additionally he did not support his idea with scientific evidence or explain the chemical behavior of the atom. As well known, Yukawa cached an idea of meson theory by reading the Fermi's paper on beta-decay based on quantum field theory. 19. At distances of a few fermi, the force between two nucleons is weakly attractive, indicated by a negative potential. In 1935, Yukawa proposed the existence of a new kind of particle, the meson, in order to explain how protons and neutrons in the nucleus interact. Hideki Yukawa, incentor of the meson theory of nuclear forces, was the fifth of seven children . In 1803, John Dalton, proposed his atomic theory. .
