The classical theory of light colors: a paradigm for description of particle interactions
There are two contemporary concepts which, coming from the physics of past, carry, in our opinion, a special meaning for the physics of future: the concept of asymptotic freedom and the holographic principle. The first one helped rounding the quantum chromodynamics (QCD) as a science of strong interactions of what are currently considered fundamental material particles. It advocates, roughly speaking, the light-like behavior of the particles involved in strong interactions. The second one, closely correlated to the idea of asymptotic freedom, but aiming to cover the whole range of fundamental forces, advocates the idea of two degrees of freedom in the description of fundamental interactions. This, again, is a fundamental classical characteristic of light.
