"Today it is known that the atomic nuclei are composed of smaller constituents, the quarks. A quark is always bound with two other quarks, forming a baryon or with an antiquark, forming a meson. The quark model was first postulated in 1964 by Murray Gell-Mann -- who coined the name "quark" from James Joyce's novel Finnegans Wake -- and by George Zweig, who then worked at CERN. In the present theory of strong interactions -- Quantum Chromodynamics proposed by H Fritzsch and Gell-Mann in 1972 -- the forces that bind the quarks together are due to the exchange of eight gluons. On the 50th anniversary of the quark model, this invaluable volume looks back at the developments and achievements in the elementary particle physics that eventuated from that beautiful model. Written by an international team of distinguished physicists, each of whom have made major developments in the field, the volume provides an essential overview of the present state to the academics and researchers.--

Murray Gell-Mann is one of the leading physicists of the world. He was awarded the Nobel Prize in Physics in 1969 for his work on the classification and symmetries of elementary particles, including the approximate SU(3) symmetry of hadrons. His list of publications is impressive; a number of his papers have become landmarks in physics. In 1953, Gell-Mann introduced the strangeness quantum number, conserved by the strong and electromagnetic interactions but not by the weak interaction. In 1954 he and F E Low proposed what was later called the renormalization group. In 1958 he and R P Feynman w

In the 1960's, Leipzig was the center of resistance in East Germany. Harald Fritzsch, then a physics student, contemplated escape. But before he left, he wanted to demonstrate to the government that they had gone too far when they destroyed St. Paul's Church in May 1968. He accomplished that by unrolling a protest transparency in spectacular fashion. Despite the great efforts of the secret police, the STASI, the government was unable to find out who was responsible for this act. Soon after, together with a friend, Fritzsch began his journey to Bulgaria in order to escape into Turkey by traversing...
