Some implications of a scale invariant model of statistical mechanics to transport phenomena in general and the iso-spin diffusion in connection to the Onsager's reciprocity principle and the modified Helmholtz vorticity equation are discussed. The invariant forms of mass, energy, linear momentum, and angular momentum conservation equations are derived from an invariant Enskog equation of change. A scale invariant definition of Reynolds number is introduced as Reβ0 = (Lxβwxβ)/ (λxβ-1vxβ-1) and applied to describe the phenomena of super-fluidity, BEC, superconductivity, and super-luminosity (laser action) as transitions from turbulent (strongly dissipative) to laminar (weakly dissipative) flows at molecular-, atomic-, electro-, and chromo-dynamic scales, respectively. Also, a scale-invariant model of "particle" wave amplification by simulated emission of particles parallel to laser phenomenon is introduced. Finally, a model of Faraday line of force as strings of electrons and positrons is described that is in harmony with the perceptions of Dirac.
