  Far-from-equilibrium systems are ubiquitous in nature. They are also rich in
terms of diversity and complexity. Therefore, it is an intellectual challenge
to be able to understand the physics of far-from-equilibrium phenomena. In this
paper we revisit a standard tabletop experiment, the Rayleigh-B{\'e}nard
convection, to explore some fundamental questions and present a new perspective
from a first-principles point of view. How non-equilibrium fluctuations differ
from equilibrium fluctuations, how emergence of order out-of-equilibrium breaks
symmetries in the system, or how free-energy of a system gets locally
bifurcated to operate a Carnot-like engine to maintain order? The exploration
and investigation of these non-trivial questions are the focus of this paper.
