  This article attempts to use the ideas from the field of complexity sciences
to revisit the classical field of fluid mechanics. For almost a century, the
mathematical self-consistency of Navier-Stokes equations has remained elusive
to the community of functional analysts, who posed the Navier-Stokes problem as
one of the seven millennium problems in the dawn of 21st century. This article
attempts to trace back the historical developments of fluid mechanics as a
discipline and explain the consequences of not rationalising one of the
commonly agreed upon tenets - continuum hypothesis - in the community. The
article argues that 'fluids' can be treated as 'emergent' in nature, in that
the atoms and molecules in the nanometre length scale can likely be correlated
with the continuum physics at the microscale. If this is the case, then one
might start trying to find a theoretical framework that models the emergence of
fluids from atoms, effectively solving the multi-scale problem using a single
abstract framework. Cantor set with layers $N$ (N can have up to two orders of
magnitude) is presented as a potential contender (analytical framework) for
connecting the energy in molecular level $C_{1}$ at length scale $l_{cut}$ to
the energy at continuum level $C_N$ with length scale $L$. Apart from fluid
mechanics, Cantor set is shown to represent the conceptual understanding of
VLSI hardware design ($N=5$). Apart from Cantor set, an experimental technique
of architecting metafluids is also shown to solve emergence experimentally
(i.e. connect physics at specific lower scales to higher scales).
