Magnetic monopoles, alive

We review recent developments in understanding the physics of the magnetic monopoles in unbroken non-Abelian gauge theories. Since numerical data on t he monopoles are accumulated in lattice simulations, the continuum theory i s understood as the limiting case of the lattice formulation. We emphasize physical effects related to the monopoles. In particular, we discuss the mo nopole-anti monopole potential at short and larger distances as well as a d ual formulation of the gluodynamics, relevant to the physics of the confine ment.
