" From theoretical considerations, Hideki Yukawa in 1934 predicted the existence and the approximate mass of the “meson” as the carrier of the nuclear force that holds atomic nuclei together. If there was no nuclear force, all nuclei with two or more protons would fly apart because of the electromagnetic repulsion. Yukawa called his carrier particle the meson, from mesos, the Greek word for intermediate, because its predicted mass was between that of the electron and that of the proton, which has about 1,836 times the mass of the electron. Yukawa had originally named his particle the “mesotron”, but he was corrected by the physicist Werner Heisenberg (whose father was a professor of Greek at the University of Munich). Heisenberg pointed out that there is no “tr” in the Greek word “mesos”. “
