A condition in which all acting influences are canceled by others, resulting in a stable, balanced, or unchanging system.
Mental or emotional balance; poise.
Physics. The state of a body or physical system at rest or in unaccelerated motion in which the resultant of all forces acting on it is zero and the sum of all torques about any axis is zero.
Chemistry. The state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time.
The state in which market supply and demand balance each other and, as a result, prices become stable.
Investopedia Says: The equilibrium price is the price at which the supply of goods matches demand.

Status of a market in which there are no forces operating that would automatically set in motion changes in the quantity demanded or the price that currently prevails.
Condition in which the net force acting on a particle is zero. A body in equilibrium experiences no acceleration and, unless disturbed by an outside force, will remain in equilibrium indefinitely. A stable equilibrium is one in which small, externally induced displacements from that state produce forces that tend to oppose the displacement and return the body to equilibrium. An unstable equilibrium is one in which the least departures produce forces tending to increase the displacement. A brick lying on the floor is in stable equilibrium, while a ball bearing balanced on a knife-edge is in unstable equilibrium.
state of balance. When a body or a system is in equilibrium, there is no net tendency to change. In mechanics, equilibrium has to do with the forces acting on a body. When no force is acting to make a body move in a line, the body is in translational equilibrium; when no force is acting to make the body turn, the body is in rotational equilibrium. A body in equilibrium at rest is said to be in static equilibrium. However, a state of equilibrium does not mean that no forces act on the body, but only that the forces are balanced. For example, when a lever is being used to hold up a raised object, forces are being exerted downward on each end of the lever and upward on its fulcrum, but the upward and downward forces balance to maintain translational equilibrium, and the clockwise and counterclockwise moments of the forces on either end balance to maintain rotational equilibrium. The stability of a body is a measure of its ability to return to a position of equilibrium after being disturbed. It depends on the shape of the body and the location of its center of gravity (see center of mass). A body with a large flat base and a low center of gravity will be very stable, returning quickly to its position of equilibrium after being tipped. However, a body with a small base and high center of gravity will tend to topple if tipped and is thus less stable than the first body. A body balanced precariously on a point is in unstable equilibrium. Some bodies, such as a ball or a cone lying on its side, do not return to their original position of equilibrium when pushed, assuming instead a new position of equilibrium; these are said to be in neutral equilibrium. In thermodynamics, two bodies placed in contact with each other are said to be in thermal equilibrium when, after a sufficient length of time, their temperatures are equal. Chemical equilibrium refers to reversible chemical reactions in which the reactions involved are occurring in opposite directions at equal rates, so that no net change is observed.
According to occultist Éliphas Lévi, magic harmony is said to depend upon equilibrium. In ceremonial magic operations, if the will of the operator is always at the same tension and directed along the same line, moral impotence will ensue. On the other hand, mediums who submit themselves passively to psychic forces are equally unbalanced. Lévi extols the all-powerful action of harmony in exalting the soul and giving it rule over the senses, guided by the will.

A condition in which all influences acting cancel each other, so that a static or balanced situation results. In physics, equilibrium results from the cancellation of forces acting on an object. In chemistry, it occurs when chemical reactions are proceeding in such a way that the amount of each substance in a system remains the same. (Seechemical equilibrium.)
In economics, a state of the economy in which for every commodity or service (including labor), total supply and demand are exactly equal. Equilibrium is never actually attained; it is approximated by movements of the market.
Keynesian economics departed from conventional economic theory in demonstrating that economic equilibrium and full employment need not occur together. Therefore, as a system tends toward equilibrium, it might not eliminate unemployment.

Plot
A man who dares to feel finds his life in danger in this cautionary science fiction drama. In the future, after a Third World War has decimated much of the Earth's population, a new nation known as Libria rises up under the unquestioned leadership of Dupont (Angus MacFadyen). Believing human emotions and their expression were to blame for the failings of past societies, The Father has decreed that all citizens must take a daily dose of Prozia II, a drug which levels out the emotional landscape, and that all forms of creative expression are against the law; violating either regulation can be punished by death. John Preston (Christian Bale) is a Grammaton, an elite law enforcement officer who tracks down and punishes "sense offenders." One day, Preston accidentally fails to take his Prozia II, and for the first time begins experiencing emotions himself. Preston becomes aware of an underground of rebels who refuse to take their medication and have embraced art and literature, and he finds himself becoming infatuated with one of their number, Mary O'Brian (Emily Watson). Equilibrium is the second feature-length directorial effort from Kurt Wimmer, whose screenwriting credits include The Thomas Crown Affair and Sphere. ~ Mark Deming, All Movie Guide
Review
For action movie fans, it's rare to find a film that has anything on it's mind other than trying to out-explode the biggest and latest brainless romp in the theaters. With director Kurt Wimmer's Equilibrium, audiences were given a little more to chew on, deliberately echoing Orwell's 1984, with touches of Brave New World and Fahrenheit 451 just to be safe. While some scoured at the heavy-handedness of the science fiction material and the lack of originality in the ideas, those who stayed were treated to one of the freshest films in a now-tired genre. By inventing a fighting technique known as "Gun-Kata," the filmmakers created an excuse for filmgoers to buy into some of the most stylish, fun, and kinetic gun battles this side of Hong Kong cinema. Far too easily compared with The Matrix, this low-budgeter relies on virtually no wire-work and instead turns the focus onto the play of light, well-staged choreography, and fierce editing as its main filmmaking allies. It's surprising then that some of the film's best moments are the most quiet ones. Christian Bale's awakening to the senses he's been taught and bred to ignore is note-perfect and the most memorable of the film. With equally strong performances from the rest of the cast and gorgeous art design surrounding them, Equilibrium deserved more of a chance than its studio, Dimension, originally gave it upon release. And while the ideas it embraced admittedly weren't the most original, they are timeless and strong enough to be reexamined and interpreted every so often by artists such as these. Exciting, beautiful, and filled with probably more intelligence than it should have, Equilibrium is the thing that cult classics are made of. ~ Jeremy Wheeler, All Movie Guide

True happiness consists in decreasing the distance between our desires and our powers, in establishing a perfect equilibrium between power and will.
— Elizabeth Rapaport.
A dynamic equilibrium occurs when two reversible processes proceed at the same
rate. Many processes (such as some chemical reactions) are reversible and when at
dynamic equilibrium the forward reaction will occur at the same rate as the reverse reaction such that there is no further change
in concentration of reactants or products.
An example of the process can be imagined if a bucket is filled with water and placed in a small room. The water from the
bucket will evaporate, and the air in the room will start to become saturated
with water vapor. Eventually, the air will be completely saturated with water, and the level
of water in the bucket will stop falling. However, water from the bucket is still evaporating. What is happening is that
molecules of water in the air will occasionally hit the surface of the water and condense back
into the liquid water, and this occurs at the same rate at which water evaporates from the bucket. This is an example of
dynamic equilibrium, because the rate of evaporation equals the rate of condensation.
The concept of dynamic equilibrium is not limited to simple changes of state such as that described above. It is often applied
to the analysis of chemical reaction kinetics, to obtain useful information about the ratios of reactants and products which will form at equilibrium. It should be noted
that at equilibrium the concentrations of the reactants and the concentrations of the products are constant.
The term also has applications across a wide range of disciplines. While it may be applied to less physical systems in these
fields, it still relates to a stable situation maintained by balancing processes. For example: in economics it may be used to refer to the constant flux of capital
in otherwise stable markets; in ecology, an unchanging population of organisms results from the balancing of
birth rate against death rate.
This term can also be used to refer to a steady state (i.e., a state which isn't a true
equilibrium, but does not change with time). This can only happen if the system is in contact with an environment which is not in
equilibrium.
