This is a study of the classical physical and mathematical principles that govern turbulent fluid dynamics. Contrary to the general conception that views turbulent flows as incomprehensible; it can, in fact, be cast as a deterministic phenomenon that obeys a universal law. This universal law was introduced by A. N. Kolmogorov in the work that has now been immortalized as K41, widely accepted as among the most significant contributions to fluid dynamics research. A presentation of the universal law of multiscale turbulence is given here with the objective of assuaging apprehensions in regard to turbulent fluid dynamics and to garner interest in this very fascinating concept.
