This should be a place for constructive conversation. Also in the cause of clarity: I did not say that the Sagan quote is a defense of theism.
Overview[ edit ] Definitions of complexity often depend on the concept of a confidential " system " — a set of parts or elements that have relationships among them differentiated from relationships with other elements outside the relational regime. Many definitions tend to postulate or assume that complexity expresses a condition of numerous elements in a system and numerous forms of relationships among the elements.
However, what one sees as complex and what one sees as simple is relative and changes with time. Warren Weaver posited in two forms of complexity: Some definitions relate to the algorithmic basis for the expression of a complex phenomenon or model or mathematical expression, as later set out herein.
Weaver perceived and addressed this problem, in at least a preliminary way, in drawing a distinction between "disorganized complexity" and "organized complexity". In Weaver's view, disorganized complexity results from the particular system having a very large number of parts, say millions of parts, or many more.
Though the interactions of the parts in a "disorganized complexity" situation can be seen as largely random, the properties of the system as a whole can be understood by using probability and statistical methods.
A prime example of disorganized complexity is a gas in a container, with the gas molecules as the parts. Some would suggest that a system of disorganized complexity may be compared with the relative simplicity of planetary orbits — the latter can be predicted by applying Newton's laws of motion.
Of course, most real-world systems, including planetary orbits, eventually become theoretically unpredictable even using Newtonian dynamics; as discovered by modern chaos theory. These correlated relationships create a differentiated structure that can, as a system, interact with other systems.
The coordinated system manifests properties not carried or dictated by individual parts. The organized aspect of this form of complexity vis-a-vis to other systems than the subject system can be said to "emerge," without any "guiding hand". The number of parts does not have to be very large for a particular system to have emergent properties.
A system of organized complexity may be understood in its properties behavior among the properties through modeling and simulationparticularly modeling and simulation with computers. An example of organized complexity is a city neighborhood as a living mechanism, with the neighborhood people among the system's parts.
The source of disorganized complexity is the large number of parts in the system of interest, and the lack of correlation between elements in the system. In the case of self-organizing living systems, usefully organized complexity comes from beneficially mutated organisms being selected to survive by their environment for their differential reproductive ability or at least success over inanimate matter or less organized complex organisms.
Robert Ulanowicz 's treatment of ecosystems. For instance, for many functions problemssuch a computational complexity as time of computation is smaller when multitape Turing machines are used than when Turing machines with one tape are used.
Random Access Machines allow one to even more decrease time complexity Greenlaw and Hoover This shows that tools of activity can be an important factor of complexity. Varied meanings[ edit ] In several scientific fields, "complexity" has a precise meaning: In computational complexity theorythe amounts of resources required for the execution of algorithms is studied.
The most popular types of computational complexity are the time complexity of a problem equal to the number of steps that it takes to solve an instance of the problem as a function of the size of the input usually measured in bitsusing the most efficient algorithm, and the space complexity of a problem equal to the volume of the memory used by the algorithm e.
This allows classification of computational problems by complexity class such as PNP, etc. An axiomatic approach to computational complexity was developed by Manuel Blum. It allows one to deduce many properties of concrete computational complexity measures, such as time complexity or space complexity, from properties of axiomatically defined measures.
In algorithmic information theorythe Kolmogorov complexity also called descriptive complexity, algorithmic complexity or algorithmic entropy of a string is the length of the shortest binary program that outputs that string. Minimum message length is a practical application of this approach.No topic, probably, has been quite as exhaustively examined, studied, dissected, and discussed as leadership.
But much of the focus has been on how American businesses define leadership. Ancient Greek Philosophy. From Thales, who is often considered the first Western philosopher, to the Stoics and Skeptics, ancient Greek philosophy opened the doors to a particular way of thinking that provided the roots for the Western intellectual tradition.
Another factor is that the air pressure we use to make sounds is much greater when we sing.
Those who sing have to learn to breathe correctly to sustain notes for the right amount of time, and singing requires the air passages to expand and become larger. Complexity characterises the behaviour of a system or model whose components interact in multiple ways and follow local rules, meaning there is no reasonable higher instruction to define the various possible interactions..
The term is generally used to characterize something with many parts where those parts interact with each other in multiple ways, culminating in a higher order of emergence. is NOT that branch of philosophy that seeks to discover what different moral beliefs different people do in fact have Ethics is that branch of philosophy that is concerned with how we ought to live, with the idea of the good, and with the .
The Tax Protester FAQ Introduction What is the purpose of this FAQ?
The purpose of this FAQ is to provide concise, authoritative rebuttals to nonsense about the U.S. tax system that is frequently posted on web sites scattered throughout the Internet, by a variety of fanatics, idiots, charlatans, and dupes, frequently referred to by the courts as “tax protesters”.
