  The year 2022 marked the 200th anniversary of the first appearance of the
Navier-Stokes equation, a landmark in Fluid Dynamics introduced by Claude-Louis
Navier in 1822. This equation revolutionized the understanding of fluid motion
by incorporating viscosity and friction into the equations, expanding their
applicability beyond idealized fluids. In this manuscript, we explore the
historical development of the Navier-Stokes equation and its profound impact on
Fluid Dynamics over the past two centuries. From Navier's initial insights to
George Stokes' experimental validations and subsequent contributions by other
scientists, we trace the evolution of this equation. We also delve into its
practical applications, including its role in the development of Computational
Fluid Dynamics. The Navier-Stokes equation has played a pivotal role in
advancing our understanding of fluid behavior, making it a cornerstone of
modern science and engineering.
