in the autonomous system (1) yields the system
For a Hamiltonian system, a consequence of (3) is the conservation of the phase volume by the phase flow.
For a linear autonomous system the structure of phase trajectories in a neighbourhood of an equilibrium point is known, since the autonomous system is integrable [5].

 truth in mathematics
Mathematical propositions are not true because they deal in eternal or idealized entities, but because their denial is logically impossible.
Indeed, mathematics begins with a languageless activity of the mind which moves on from one thing to another but keeps a memory of the first as the empty form of a common substratum of all such moves.
Mathematics arises out of its practice, and must ultimately be a free creation of the human mind, not an exercise in logic or a discovery of preexisting fundamentals.

 Omnipelagos.com ~ article "Autonomous system (mathematics)"   (Site not responding. Last check: 2007-10-11)
In mathematics, an autonomous system or autonomous differential equation is a system of ordinary differential equations which does not depend on the independent variable.
Many laws in physics, where the independent variable is usually assumed to be time, are expressed as autonomous systems because it is assumed the laws of nature which hold now are identical to those for any point in the past or future.
It is distinguished from systems of differential equations of the form in which the law governing the rate of motion of a particle depends not only on the particle's location, but also on time; such systems are not autonomous.

 A PRIMARY SCHOOL CURRICULUM TO FOSTER THINKING ABOUT MATHEMATICS   (Site not responding. Last check: 2007-10-11)
On the other hand, some studies in the field of mathematics suggest that there are myths and prejudices about mathematics in primary schools and that the school system is partly responsible for this.
With regard to the intrinsic interest and motivation to learn mathematics, Dewey states (l967) that as soon as studies in mathematics are dissociated from personal interest and their social utility, that is, when mathematics are presented as a mass of technical relationships and formulas, they become abstract and vain for students.
It is a global and fundamental education, which encourages students to think critically and creatively about mathematics and which gives them the possibility to articulate the expression of their opinions and contentions concerning personal as well as social or moral problems.

 What are Fractal Systems? (Complex Adaptive Systems)
A period of flux occurs in all the populations in the system until a new balance is established.
The greater the variety within the system the stronger it is. In fact ambiguity and paradox abound in fractal systems which use contradictions to create new possibilities to co-evolve with their environment.
The ways in which the agents in a system connect and interact to one another is critical to the survival of the system, because it is from these connections that the patterns are formed and the feedback disseminated.

 TNE Standards - Mathematics
By this we mean that prospective teachers should be able to recognize potential connections among ideas in mathematics, recognize the correctness (or incorrectness) of mathematical arguments, and be able to use mathematics successfully to solve a wide range of problems.
They should also be committed and prepared to help their own pupils gain an understanding of mathematics, to apply their understanding to produce and recognize valid mathematical reasoning, and to solve problems both within and outside of mathematics.
The precise explanation of a mathematical solution, regardless of the specific problem, starts with definitions and axioms, and builds from there to basic properties, which are then used to obtain desired results.

 Aristotle and Mathematics (Stanford Encyclopedia of Philosophy)
It is not clear why Aristotle thinks one needs to learn mathematical axioms to learn anything, unless he means that one needs to learn them to learn anything in a mathematical subject or that axioms are so basic that they should form the first part of one ‘s learning.
The objects studied by mathematical sciences are perceptible objects treated in a special way, as a perceived representation, whether as a diagram in the sand or an image in the imagination.
The parts of a mathematical object which do not occur in the definition of the object, e.g., acute angle is not in the definition of right angle, but is a part of it and so is a non-perceptible material part of the angle (Metaphysics vii.10, 11).

 Is Society a Self-Organizing System?
Notions of systems which organize the social process autonomously have been around in social theory, particularly on the marxist side, but these theories were suspect because of their lack of analytical rigor, and consequently of sophistication in empirical design.
The crucial point is that the system is healthy as long as it communicates what it is supposed to communicate, as long as the subsystems perform their operations at the right moments in time, and as long as each subsystem additionally self-controls its structural organization with reference to its operation.
As we saw in the paradigm example, in a self-organizing system control flip-flops: the contributors to the genesis and the maintenance of the system are no longer able to control the system's substance, although this substance is logically a result of their interactions.

 SATBOT I: Prototype of a Biomorphic Autonomous Spacecraft
The human nervous system is an analog system which consists of approximately ten trillion neurons,[3] each having the ability to receive, process, and transmit electrochemical signals over complex pathways.
