  Deterministic Chaos and the Simulated Universe - Kaedrin Weblog
Historically, it was thought that all processes occurring in the universe were deterministic, and that if we knew enough about the rules governing the behavior of the universe and had accurate measurements about its current state we could predict what would happen in the future.
And in a literal sense, an infinite number of universes of all types and states should exist in thin air, indifferent to whether or not we discover the rules that exactly reveal their outcome.
I kinda mentioned that the article assumed the universe was deterministic, but left it at that and focused on chaos, because I think it's an interesting subject.

 The Concept of God in Islam: An Introduction
Thus, while the view that the universe is deterministic is demonstrably indemonstrable, the idea of a non-deterministic universe may be demonstrable.
For, in a deterministic universe, all human choices must be determined by a system knowable by man, and it is less understandable how this situation can produce the experience of "free will" than if the universe is non-deterministic.
In such a universe, the emergence of life and, in particular, human life, with its spiritual concerns and its willingness to sacrifice for higher goals, is more likely to say something about the universe as a meaningful reality than being a result of mere coincidences in an otherwise mindless universe.

 The Gestalt of Determinism
For example, it may be possible to completely specify the universe based on the contents of a particular cross-sectional slice, together with a simple set of fixed rules for recursively inferring the contents of neighboring slices in a particular sequence, whereas other sequences may require a vastly more complicated "rule".
However, in a deterministic universe this chain of implication is merely a descriptive convenience, and cannot be regarded as the effective mechanism by which the events "come into being".
The static view is fully consistent not only with the Newtonian universe that Laplace imagined, but also with the theory of relativity, in which the worldlines of objects (through spacetime) can be considered to be already existent in their entirety.

 Chaos Frees the Universe
Laplace argued that, given the state of the Universe at any one instant, the entire cosmic future would be uniquely fixed, to infinite precision, by Newton's laws.
The concept of the Universe as a strictly deterministic machine governed by eternal laws profoundly influenced the scientific world view, standing as it did in stark contrast to the old Aristotelian picture of the cosmos as a living organism.
As Ilya Prigogine, a theoretical chemist at the University of Brussels, has eloquently expressed it, God is reduced to a mere archivist, turning the pages of a cosmic history book that is already written.

 Scientific determinism - Wikipedia, the free encyclopedia
Hawking admits that even the uncertainty principle does not absolutely rule-out a kind of determinism "in principle", and says that quantum mechanics may very well allow the universe to be deterministic.
Logic holds that deterministic progression occurs throughout the universe regardless of human knowledge.
The binding deterministic component is that each such theoretical snapshot must strictly accord to the inseparable and inflexible governance of physical laws and potentials.

 Temporal Reference Frames, a deterministic model, and the misconception of "irrevesibilty"
Just as you can imagine 2D slices of the universe, and you can move the cursor to see this slice of the universe at a different time, you can likewise rotate what axis you are focusing on.
And after the negative universe has its negative contraction, there is another big bang which is identical to the previous big bang that we experienced some 20 billion years ago.
You really can't talk about the "origin" of the universe as you are accustomed to talking about the origin of things you witness in your life because TIME itself is what you are talking about.

If the universe is deterministic, your brain function and resultant body motion may be determined from the initial state of the universe.
If the universe is not deterministic, the wavefunction of your brain function and resultant body motion may still be determined from an initial state, tho the classical observables resulting from "measurement" will be randomly determined by this wavefunction.

 Does God Play Dice?
Notice that in order to show that a system is deterministic, we don't actually have to predict what it will do: we just have to be assured that on both occasions it will do the same thing.
So whether we think that our universe as a whole is random depends on what brand of physics we currently espouse, and since we can't actually run the entire universe twice from the same initial conditions the whole discussion becomes a trifle moot.
Nonetheless, we see that deterministic systems behave differently from random ones, and that certain features of that difference lead to quantitative measures of the degree of chaos that is present.

 Maximizing Liberty
In a deterministic universe, we understand that a criminal’s career is not a matter of an unconditioned personal choice, but fully a function of a complex set of conditions, genetic and environmental, that interact to produce the offender and his proclivities.
If we lived in a universe in which moral agents were in some sense causal exceptions to nature, or were in some sense self-caused, then this question poses little difficulty.
University of California at Riverside philosopher John Martin Fisher expresses this point nicely: “If causal determinism is false, then it would seem that everything about the past and the laws of nature — including all the facts about me (my character, values, personality, and so forth) — leaves it open which path will be selected.

 Mind-Brain Identity (essay)
The denumerability of states of the universe is a necessary condition of these states being finitely representable, which in turn is a necessary condition of there being an effective procedure for computing the state of the universe at some time given the state at some preceding time.
Even if the present material state of the universe is sufficient to establish precisely the mental state of every individual in that universe, it does not follow that it is enough to establish future material states of the universe, and hence future mental states of individuals.
The deterministic universe which I have outlined so far is not a causal universe, or at least not necessarily one.

 NPQ
But theorists in the physical sciences always tried to say that the universe is "time reversible"; that the present determined the future just as it could serve to reconstruct the past.
Men like Einstein aimed to demonstrate that human subjectivity was merely an illusion and that reality consisted of a transparent, intelligible Universe, purged of everything that touches on the lives of man, of painful, nostalgic memory of the past, of fear or hope for the future.
Einstein said that he believed in a deterministic universe, yet at the same time he also said he believed in the creative activity of the human mind.

 Juan Antonio Navarro PĂ©rez: The Universe as a Video Game
For example, the Universe is the world created inside the game (with all its trees, mountains, and characters randomly running without direction; in something like StarCraft it might also include solar systems, other planets, etc.) and physics are the rules that govern the Universe (the code or program of the game).
In fact, when working on the microscopic level of the universe, the behaviour of elementary particles is not deterministic at all.
The crux: non-deterministic Turing-machines are equivalent to deterministic Turing-machines.

Because of the way his zygote was produced in his deterministic universe, Ernie is not a free agent and is not morally responsible for anything.
Imagine a deterministic universe U* that is a lot like the one at issue, U, but in which Z comes into being in Mary in the normal way and at the same time.
Suppose that incompatibilists have the intuition reported in premise 1 — that because of the way his zygote was produced in his deterministic universe, Ernie is not a free agent and is not morally responsible for anything — partly because they believe that incompatibilism is true.

 What is Chaos?: Determinism   (Site not responding. Last check: 2007-10-17)
According to the deterministic model of science, the universe unfolds in time like the workings of a perfect machine, without a shred of randomness or deviation from the predetermined laws.
Newton demonstrated that his three laws of motion, combined through the process of logic, could accurately predict the orbits in time of the planets around the sun, the shapes of the paths of projectiles on earth, and the schedule of the ocean tides throughout the month and year, among other things.
Newton's laws are completely deterministic because they imply that anything that happens at any future time is completed determined by what happens now, and moreover that everything now was completely determined by what happened at any time in the past.

 Deterministic Universe? - College Discussion
So even if you had a totally deterministic model of the universe, you cannot predict the current state based on a previous state (or a set of measurements) with total accuracy.
Thus, any prediction of the state of the universe at time t is a probabilistic measure.
As a result, a two tiered physics world has formed, where General Relativity defines the universe because the gravitational force is predominant whilst Quantum Mechanics defines elementary particles since here the strong nuclear, weak and electromagnetic forces dominate.

This observation is outside of time and chooses one universe and its entire history from a population of potential universes.
That the universe viewed outside of time is deterministic is unquestionably true, in the sense that once created, it is immutable.
In exactly the same way, it is all right that the atemporal universe is deterministic while the temporal universe is not, even though it is the same universe in both cases.

 From Metaphysical Freedom To Civil Liberties: A Cybernetic Account Of Natural Law
Thus, consider the universe as observable by people inside the universe; in the phenomenological perspective, this universe is actually an Ontology of Human Action, comprehending everything that humans may observe and act upon, and the feedback that may they receive from such action.
For any deterministic model of the universe as we may know it, there will be an elementarily equivalent (to use the vocabulary of model theory) non-deterministic model of the same knowable universe, and conversely.
Arbitrary choice of names in languages, or deterministic nature in physical models, etc., are among the many details that belong to the ontology of their respective kind of representation.

 Determinism - Wikipedia, the free encyclopedia
It is a popular misconception that determinism necessarily entails that humanity or individual humans have no influence on the future and its events (a position known as Fatalism); this is not obviously the case, and the subject is still debated among metaphysicists.
By 'soul' in this context is meant an autonomous immaterial agent that has the power to control the body but not to be controlled by the body of which there is no evidence (this theory of determinism thus conceives of conscious agents in dualistic terms).
Determinists argue that this is a fallacious appeal to consequences, that the factual or logical truth of the matter is entirely independent of whether that truth is perceived as beneficial.

 Quantum Physics
When Stephen W. Hawking says that the universe is non-singular, he isn't claiming it's non-deterministic and he's basing his judgement on an interpretation of fl hole evaporation (the belief that information is destroyed during the process) over which there is a lot of controversy.
But since everyone still "knows" that the universe is non-deterministic, I also predict that physicists at large will only believe this evidence by 2040 and the general population by 2070.
One difference between the initial conditions and non-determinismic effects is that the former are located at an edge of the universe whereas the latter are embedded within it.

Invoking such an effect is currently the most popular method for explaining recent observations that the universe is expanding at an accelerating rate, as well as accounting for a significant portion of the missing mass in the universe.
During the late 1990s, observations of type Ia supernovae ("one a") suggested that the expansion of the universe is accelerating.
At the moment, many researchers believe that dark energy may be a foam of quantum particles that exists throughout the vacuum of space.

 Are computers becoming more human, or are humans becoming more like computers?   (Site not responding. Last check: 2007-10-17)
The definition I have for deterministic is "an inevitable consequence of antecedent sufficient causes", which does not imply anything about the need to be able to predetermine those inevitable consequences.
I defined the universe as everything that can impact me. This means that I exclude the possibility of a system that can have any dependency on state that is not contained by the system.
Something that is deterministic, can not by virtue of the fact that it is deterministic, render results that are non-deterministic without constraining the scope in which you define determinism such that you can rely on unknown state.

Incompatibilists dread determinism because they suspect that a deterministic universe would lack the sorts of open possibilities that we cherish and deprive us of the ability to cause changes to the world in a meaningful way.
Ideally, science strives for a description of the universe that is as thorough and comprehensive as possible, composed in an orderly mathematical idiom.
To put it graphically, the universe could be deterministic on even days of the month and indeterministic on odd days, and we'd never notice a difference in human opportunities or powers; there would be just as many triumphs-and just as many lamentable lapses-on October 4 as on October 3 or October 5.

In Spinoza Einstein also found a champion for his belief in a deterministic universe that could be understood by human reason.
When astrophysicist Edwin Hubble's observations revealed in 1929 that the galaxies in our universe were indeed hurtling away from each other, Einstein realized that this error had cost him the opportunity to be the first to announce that the cosmos was expanding.
Perhaps the most telling indication of Einstein's faith in a deterministic universe can be found not in what he himself believed but in the rival physics theory he refuted: quantum mechanics.

 stoicism
To say the universe is one vast living organism was to say that the universe has a body, the whole physical world, or what stoicsd called "Nature," and also that this body is directed by a universal "soul" which the Stoics called "The Logos" and often identified with Zeus.
As the Universe is a vast living organism directed by a universal mind or logos, one can understand the nature of reality when one can understand how The Logos directs the universe.
But this is inconsistent with their universal determinism; if living organisms are just material things and that's why they are determined, then attitudes of living organisms are just special properties of material things, and they should be just as much determined as the consequences of our actions.
