 GLOSSARY
In quantum theory for example it is well known that you may change the phase of the wave functions by an arbitrary amount without altering any the physical content or structure of the theory, provided that you change the all wave functions in the same way, everywhere in space.
However when the string theories where discovered and found to only exist in 10 dimensions, this 11 dimensional theory was largely ignored (prior to string theory a 4 dimensional form of it was once heralded by Stephen Hawking as the fundamental theory of nature).
Sting theories (there are five consistent string theories known) are quantum theories where the underlying object is a one dimensional string in spacetime (as opposed to particles in quantum field theories).

 Nonlinear Dynamics and Complex Systems Theory (Glossary)   (Site not responding. Last check: 2007-11-03)
An order parameter is a scalar or vector parameter associated with a continuous phase transition that determines the physical nature of the transition.
In the case of a fluid, for example, the order parameter is a scalar and is the difference in density between the liquid and vapor phases.
It is also a universal theory in that it predicts that the global properties of complex systems are independent of the microscopic details of their structure, and is therefore consistent with the "the whole is greater than the sum of its parts" approach to complex systems.

Darwin's theory of evolution by natural selection enabled this process to be thought of as blind and purposeless, and this interpretation is central to neo-Darwinism (q.v.), the dominant orthodoxy in modern biology.
In biology, the mechanistic theory states that living organisms are nothing but inanimate machines or mechanical systems: all the phenomena of life can in principle be understood in terms of mechanical models and can ultimately be explained in terms of physics and chemistry.
It differs from Darwin's theory in that it denies the possibility of Lamarckian inheritance (q.v.); heredity is explained in terms of genes passed on by Mendelian inheritance (q.v.).

 Set Theory Glossary   (Site not responding. Last check: 2007-11-03)
In set theory the word "interval" is often informally used to mean interval class, the latter of which is of greater generality.
Note that an ordered set may be arranged in a non-temporal dimension, e.g., an alphabetical pitch order (e.g., A# B C# D).
It has also been claimed that the interval order is maintained, but this is not so either since any transformation may occur with differing melodic contours and registrations; besides, all the set forms cannot and do not have the same interval order.
