Présentation de Action Concept

Action is a part of an alternative approach to finding such equations of motion. Classical mechanics postulates that the path actually followed by a physical system is that for which the action is minimized , or more generally, is stationary.

In other words, the action satisfies a variational principle: the principle of stationary action see also below. The action is defined by an integral , and the classical equations of motion of a system can be derived by minimizing the value of that integral.

This simple principle provides deep insights into physics, and is an important concept in modern theoretical physics.

Action was defined in several now obsolete ways during the development of the concept. Expressed in mathematical language, using the calculus of variations , the evolution of a physical system i.

Several different definitions of "the action" are in common use in physics. However, when the action pertains to fields , it may be integrated over spatial variables as well.

In some cases, the action is integrated along the path followed by the physical system. The action is typically represented as an integral over time, taken along the path of the system between the initial time and the final time of the development of the system: [4].

For the action integral to be well-defined, the trajectory has to be bounded in time and space. In classical physics , the term "action" has a number of meanings.

This principle results in the equations of motion in Lagrangian mechanics. Here the input function is the path followed by the physical system without regard to its parameterization by time.

For example, the path of a planetary orbit is an ellipse, and the path of a particle in a uniform gravitational field is a parabola; in both cases, the path does not depend on how fast the particle traverses the path.

Hamilton's principal function is defined by the Hamilton—Jacobi equations HJE , another alternative formulation of classical mechanics.

In other words, the action function S is the indefinite integral of the Lagrangian with respect to time. When the total energy E is conserved, the Hamilton—Jacobi equation can be solved with the additive separation of variables :.

The physical significance of this function is understood by taking its total time derivative. The Hamilton—Jacobi equations are often solved by additive separability; in some cases, the individual terms of the solution, e.

This is a single variable J k in the action-angle coordinates , defined by integrating a single generalized momentum around a closed path in phase space , corresponding to rotating or oscillating motion:.

The variable J k is called the "action" of the generalized coordinate q k ; the corresponding canonical variable conjugate to J k is its "angle" w k , for reasons described more fully under action-angle coordinates.

The integration is only over a single variable q k and, therefore, unlike the integrated dot product in the abbreviated action integral above.

The J k variable equals the change in S k q k as q k is varied around the closed path. For several physical systems of interest, J k is either a constant or varies very slowly; hence, the variable J k is often used in perturbation calculations and in determining adiabatic invariants.

See tautological one-form. In Lagrangian mechanics, the requirement that the action integral be stationary under small perturbations is equivalent to a set of differential equations called the Euler—Lagrange equations that may be obtained using the calculus of variations.

The action principle can be extended to obtain the equations of motion for fields, such as the electromagnetic field or gravitational field.

The Einstein equation utilizes the Einstein—Hilbert action as constrained by a variational principle.

The trajectory path in spacetime of a body in a gravitational field can be found using the action principle. For a free falling body, this trajectory is a geodesic.

Implications of symmetries in a physical situation can be found with the action principle, together with the Euler—Lagrange equations , which are derived from the action principle.

An example is Noether's theorem , which states that to every continuous symmetry in a physical situation there corresponds a conservation law and conversely.

This deep connection requires that the action principle be assumed. In quantum mechanics, the system does not follow a single path whose action is stationary, but the behavior of the system depends on all permitted paths and the value of their action.

The action corresponding to the various paths is used to calculate the path integral , that gives the probability amplitudes of the various outcomes.

Although equivalent in classical mechanics with Newton's laws , the action principle is better suited for generalizations and plays an important role in modern physics.

Indeed, this principle is one of the great generalizations in physical science. It is best understood within quantum mechanics, particularly in Richard Feynman 's path integral formulation , where it arises out of destructive interference of quantum amplitudes.

Maxwell's equations can also be derived as conditions of stationary action. If instead, the particle is parametrized by the coordinate time t of the particle and the coordinate time ranges from t 1 to t 2 , then the action becomes.

The action principle can be generalized still further. One half of the subjects would hear a low tone after pressing the left key, and a high tone after pressing the right key map A and the other half would hear the opposite key-tone mapping map B.

They performed boring! In the second part of the experiment, subjects were instructed to respond to tones as instructed. The subjects, however, were divided into two groups: the reversal and the non-reversal group, each consisting of equal numbers of map A and map B subjects.

In the non-reversal group, subjects were asked to respond to a tone with the key consistent with their practiced mapping. For example, map A subjects were asked to press the left key after a low tone and the right key after a high tone.

In the reversal group, subjects were asked to respond to a tone with the opposite key. For example, map A subjects were asked to press the left key after a high tone and the right key after a low tone.

The nonreversal group responded faster with less errors in the test phase, as expected. It makes sense that they had associated the keys with the same tones that were used in the test phase.

However, the experiment had another aspect. In one series of test phases, after hearing the prompt tone and pressing the key, the subjects would hear the practiced key tone.

For example, a reversal map A subject would hear a high tone, press the left key as instructed, then hear the low tone due to pressing left.

This way they could not ignore the action-effect. In another series, the subjects would not hear the practiced tone after each key press. This way they had a chance of "practicing out" the previously acquired action-effect.

Non-reversal subjects always responded in the test phase within about ms, with or without the after-tone. With the after tone, reversal subjects responded within about ms without much improvement over time.

Without the inconsistent after-tone, however, reversal subjects quickly started responding within about ms. The result of the experiment indicated not only that the unconscious acquisition of action-effects help a subject choose actions as predicted by the action-concept model's bidirectionality, but not by other models , but also that the consistency of a known action-effect has a considerable impact even when the subjects if forced to choose.

The key ideas of the Action-Concept model are that action-effects are automatically associated with actions, the association is bidirectional, and we can plan our actions by activating desired action-effect codes instead of motor codes relying on the birectionality of the mapping.

Action concepts are generated subconsciously: you will associate effects with actions even if you are told not to, and those associations will improve or inhibit your actions in the future see the second experiment.

Furthermore, even given a routine, simple task, action-effects will still be automatically gathered and practice does not erase action-effects features see the first experiment.

Action-effects may be used to plan action in a few ways: to determine if an action is successful - we can compare the observed effect code of an action to the desired action effect code to determine if an action is complete - same as above to plan complex actions - by activating action-effect codes in sequence see the rat experiment.

The great thing about this model, as simplistic as it is, is that it makes sense and a source a great relief for me still allows for free will.

Unfortunately, it does nothing to even suggest an explanation for free will--how we might choose action-effects to activate actions.

But isn't free will more wondrous if it can't be explained? It makes sense that a baby looks around randomly without purpose and slowly starts to make more sensical movements as it gains experience.

It makes sense that we cannot perform many tasks well the first time, as simple as they are, because we have not yet acquired experience in executing them.

And it makes sense that rather than consciously planning our muscle movements to type an email, we may instead think of desired action-effects and use the bidirectionality of the action-concept to subconsciously link our action-effects to our muscle movements.

Where I leave you, the reader, stranded is with regards to the moral implications of the Action-Concept model. If action-effects and actions are automatically linked based on experience, then what if someone's well-meaning action-effects lead to bad actions because of bad experience?

Should a police academy be faulted instead of the police officer for a wrongful shooting? Can video game companies be sued for violence by children supposedly conditioned by those games?

How much weight should we give intentions versus actions if experience rather than thinking has primacy, and our consciousness, for which we are culpable, plans action-effects rather than actions?
