  Interaction picture - Biocrawler   (Site not responding. Last check: 2007-11-04)
In quantum mechanics, the Interaction picture (or Dirac picture) is an intermediate between the Schrödinger picture and the Heisenberg picture.
Whereas in the other two pictures either the state vector or the operators carry time dependence, in the interaction picture both carry part of the time dependence of observables.
Warning: Operator equations which hold in the interaction picture don't necessarily hold in the Schrodinger or the Heisenberg picture.

Using picture generation as a vehicle, many of the general ideas of the theory of computation are exemplified by results about (un)decidable, NP-complete, or efficiently solvable problems, normal forms, hierarchies of language classes, and related phenomena.

The picture was also presented in two versions: the picture followed by a relevant text (275 words) and the text followed by the picture (see ).
The multiple interactive possibility was favorable from the point of view of reception: it increased the time not only for the picture, but also for the text, as opposed to the arrangement whereby viewing and interacting with the picture were directly separated from the text reading.
Then the time for the picture in interactive and automatic ways in all was much less (26 sec.) than the time for reading the text (45 sec.), while with a side-by-side presentation the (longer) picture viewing and the (also longer) text reading took nearly the same time.

The interaction picture assigns part of the time dependence to the state vectors, and part to the operators.
Following the method used to derive the equation for the evolution of the operators in the Heisenberg picture, we can derive the equation for the evolution of operators in the interaction picture.
In the Heisenberg picture we have an equation for the evolution of operators.

 The interaction picture
In Chapter 10, we introduced the concept of pictures in quantum mechanics and discussed the difference between the Schrödinger and Heisenberg pictures.
The interaction picture can be considered as ``intermediate'' between the Schröginer picture, where the state evolves in time and the operators are static, and the Heisenberg picture, where the state vector is static and the operators evolve.
Thus, the time-evolution of the state vector in the interaction picture is given a Schrödinger equation of the form

According to Kathaleen Reid-Martinez, the Academic Director of Regent University, studies at her school indicate that the optimum class size for asynchronous CMC is 12 students.

It does not represent the whole picture of interaction, but it is still very informative and worth studying.

This common form of interaction that takes place very early in children’s lives, may provide an important source of information to them about the world around them,” says lead author, Gabrielle Simcock.

 The theory of Coulomb excitation - A qualitative approach
Coulomb interaction is symmetrical with respect to the beam and target particles, so the theoretical approach is valid for both cases of kinematics.
In the interaction picture, the Schrödinger equation of the nucleus can be broken into two parts, one for the free nucleus and one for the electric interaction of eqn.
Higher order terms of the interaction involve several intermediate states and their contribution to the system is large enough to require an explicit solution for the system of differential equations.

 The Picture of Man
Since we as humans are so complex, as is the everyday events in his life, with the relationships, circumstances and interaction, the picture of man was designed so that we have a way of seeing in graphics what is going on within the mind/spirit/awareness and how that relates to X and the physical body.
All of what goes on within is being influenced by the four-dual basic urges [review under "Illustrations" on the main web page] and the unconscious purpose of living of being non-disturbed.
This unconscious purpose of living to be non-disturbed is described in The Picture of Man in the "Basic Section" of the main web page; and in About Babies under "Workshops" in the paragraphs under "Being Born".

Therefore, they present a layered model for the interface between an application's functionality and its UI which will especially be useful for the design of UIs for multi-tasking, multi-windowing systems that support a free choice of input and output media.
By introducing these layers, the authors want to achieve ``a clear separation of application functionality from dialog functionality, and a clear responsibility for the different actions that are involved in a dialog.'', i.e.

Parents who engage in the age-old tradition of picture-book reading are not only encouraging early reading development in their children but are also teaching their toddlers about the world around them, according to a study in the November issue of Developmental Psychology, published by the American Psychological Association (APA).
This finding shows that interactions with life-like color pictures can aid in children's learning.
"The results expand our understanding of the development of pictorial competence in the second year of life and point to an interaction between symbolic and general representational capacities in the performance of very young children," said Simcock.
