Chaos and complexity can both be viewed as a theory of formal social systems.
This couldn't happen in nature (or, more precisely, could in theory, but is extremely unlikely).
But all in all, the theory seems to hold.
Sure, it isn't as big a force as Democratic Peace Theory or Mutually Assured Poverty.
Modern history, in theory, rejects both these principles.
Thought topics available within the theory are psychoanalysis, radical political thought, and critical theories of art and culture.
Here again, apart from this theory, there is no obvious reason why the composition of different substances should be related in so simple a way.
Biomedical gerontologist Aubrey de Grey maintains that aging is caused by seven underlying factors, each of which can, in theory, be countered.
What if machines did all the things they could in theory do?
No matter why the theory works, is it good for the world that it does.
What theory and science is possible about a matter the conditions and circumstances of which are unknown and cannot be defined, especially when the strength of the acting forces cannot be ascertained?
The theory seems irrefutable just because the act of transference of the people's will cannot be verified, for it never occurred.
Dalton (1803) gave the atomic theory a quantitative form, and showed that, by means of it, a vast number of the facts of chemistry could be predicted or explained.
If their view is correct, the theory appears to be a remarkable example of deductive reasoning.
To see how this law follows from Dalton's theory let us consider his diagrams for the molecules of water, ethylene and the oxides of carbon.
Otherwise Berthollet's position would have been a much stronger one, and the atomic theory might have had to wait a long while for acceptance.
The above statement does not by any means exhaust the possible predictions that can be made from the atomic theory, but it shows how to test the theory.
If chemical compounds can be proved by experiment to obey these laws, then the atomic theory acquires a high degree of probability; if they are contradicted by experiment then the atomic theory must be abandoned, or very much modified.
The atomic theory has been of priceless value to chemists, but it has more than once happened in the history of science that a hypothesis, after having been useful in the discovery Present and the co-ordination of knowledge, has been aban- position doned and replaced by one more in harmony with later of the discoveries.
Some distinguished chemists have thought atomic that this fate may be awaiting the atomic theory, and that in future chemists may be able to obtain all the guidance they need from the science of the transformations of energy.
As a psychologist de Tracy deserves credit for his distinction between active and passive touch, which developed into the theory of the muscular sense.
At that period geographers regarded the Senegal as the termination of the Niger, a theory held until Mungo Park's demonstration of the eastward course of that stream.

A theory that has received much support in the past attributes the reflections to thin bubbles of water, similar to soap-bubbles, in which form vapour was supposed to condense.
The theory was developed by R.
No form of the elastic solid theory is admissible except that in which the vibrations are supposed to be perpendicular to the plane of polarization, and the difference between one medium and another to be a difference of density only (Phil.
