Interpreting Quantum Chromodynamics from Spin Glass- and Polymer Analogies

In an informal way some kind of Ising Lattice QCD is introduced which allows to interprete and discuss parts of the well-known theory of Quantum Chromodynamics (confinement, quarks and gluons etc.) from simple phenomena of magnetism and polymer physics. Also the viewpoint of duality is stressed. Moreover, the non-abelian character of the Lie Group SU(3) is important. Essential arguments for confinement and asymptotic freedom are given at the very end of the manuscript, after an appendix.
