Dear tpaine, please calm down, and realise you are in the company of friends. There's no reason at all for you to be so "agitated."
(I'm still thoroughly perplexed as to the gist of your argument here....)

Whether or not there are truly random occurences in Nature, we may often treat events as random when these events are made up of many small causes. Brownian motion is the easiest example. A particle undergoing Brownian motion is so jumpy that it has no defined velocity. Einstein and Smoluchowski made a great leap forward when they showed that the position not the velocity of the particle was what could be described. (The position moves "randomly" but total displacement is proportional to the square root of the time.)
In one sense: "Probability Is as Probability Does." (me) Any system satisfying Kolmogorov's axioms may be treated probabilisitically. (There are other axiom sets: de Finetti, Khinchine, von Mises [brother of Ludwig], etc.; these also work but the questions are subtly different.) Jon von Plato has a (rather technical) book on the subject.
Several people have looked at "randomly" occuring events to establish how one should deal with things. Nicole d'Oresme (1323-1382) (No, it wasn't a girl's name then.) was interested in the permanence of the solar system and was opposed to the Stationary Earth Theory as accepted at the time. (He later changed his mind.) Oresme showed that if the rotation period of the earth (day) and the revolution about the sun (year) were not comensurable, then eclipses would happen at different spots on the earth. He also pointed out that the sun would never be in the same place over the earth at an equinox. In addition he was of the opinion that non-comensurablilty was more likely than comensurablity. (Comensurable number have a rational ratio.)
Continuing toward modern times, it was shown by several (Kroneker for example) that on a square billards table, if the tangent of the x and y velocity components of a particle were rational, the particle would trace out a periodic pattern. (Reflecting boundary.) If irrational, the paths would be dense. Dense paths allow time averages to be equal to space averages. (von Neumann, Birkoff, etal.) This means that the time spent in a section of the table would be proportional to the area of that section. If one makes a square table with two opposite side replaced by semicircles, even rational velocities lead to dense paths. (Except for those exactly parallel or vertical to the sides.)

Thank you so very much for your post at 4600!When we are dealing with problems relating to God, it seems to me we have to draw distinctions between what man sees, and what God sees. And as to the latter, no human being can say what that is. When I mentioned God in the context of temporality, I was only referring to the human habit of seeing things in time.
But God is not at all bound by time. Time is but an image of God's eternity, part of His creation.
I'm back to being in exact agreement with you! Yeehaw!
To: betty boop
Me agitated? Hardly.
-- On the contrary, I merely asked you - 'why the 'low opinion' dig? -- You can't answer, so be it. Apparently you don't even think that having a 'low opinion of humanity' is a little 'dig'? Taking a bit of a shot?
Don't try to BS an old bs'er betty. Such hypocrisy is really amusing, imo.
To: Doctor Stochastic
Thank you so very much for your post and all the excellent examples! The last one about the billards table is particularly engaging to me. You've given me much to research! Thank you! But focusing narrowly on algorithmic randomness, is there any reason not to use the Chaitin/Kolmogorov definition?
To: Aric2000
Matter cannot organize itself. -me- PROVE IT!!
First of all, you cannot prove a negative. Second of all, it is evolutionists that claim that matter can indeed organize itself. You are the ones who need to provide the proof. Now of course you cannot because you know my statement is true so you are just using the usual rhetorical games instead of providing evidence for your position.

Every saint was a sinner once. (The great Doctor of the Church, Augustine, comes handily to mind.)
We are both sinners, which hardly makes us unique. But we pray to the Lord for forgiveness of our sins, and for the renovation of our souls. He sees our love for Him, and so helps us in this regard.
Praise the Lord! ...

The last six sentences are the last six sentences that Nebullis posted at 4529. Was your message truncated or something? Just bad editing. Had copied his whole post and did not delete the end.

Thank you so much for your testimony! Amen to everything you said! Praise God!

Thank you so much for the explanation! I was concerned there was an addition point you wanted to make, but it got lost.

There is nothing wrong with the Chaitin/Kolmogorov definition of algorithmic randomness. It isn't too useful in the sense that no computable random sequence can exist. Knuth's Volume 2 (Chapter 3) has a discussion of randomness that is similar but one could generate a "random" sequence. (Of course, one cannot generate all such sequences nor could one tell if a given sequence was random.)
There are a couple of places where intrinsic "randomness" arises in physics. One is in Brownian motion. If trying to measure the Brownian particle more and more closely, the measuring instrument becomes subject to Brownian motion itself. Thus, even were the physical laws moving a particle deterministic, in practice, one would still have to average over the smallest measurement sizes to get results. This is a practical limit on measuring, not a claim that things such as position or velocity don't exist.
Another place is in the uncertainty relations (Heisenberg). These arise from the theory of Fourier transforms and the wave nature of particles. This is quite another problem from the Brownian motion "randomness." There doesn't seem to be anything to average over nor can one assume that the particle even has a sharply defined velocity or momentum.
I prefer in most things to avoid the term "random" because the concept isn't clearly defined. I like to talk about things like "idependent identically distributed" events. These are well defined. Of course "random variables" are not random nor are they variables. Since the 1920's, "random variable" means "measurable function."

Boyer points out that the calculus was "in the air" at the time.I am sure it was in the air. Read recently about the discovery of DNA which was also 'in the air' at the time and was a race between Watson and Crick and Linus Pauling. There comes a time when technology, knowledge and need allow certain discoveries.

My post addressed the issue that intelligence was required to manufacture stone tools, and that this information had to be passed on through education...not genetics. Yes, but your reference addressed that because it was not genetic, intelligence was determined. I do not see any difference why the same assumptions cannot be made when genes are involved and that is what I was addressing.

Capitalist economic structures also form complex structures. Local conditions often dominate the placement of buildings and of what suppliers and customers an enterprise may have. (Designed economies such as the socialist, communist, fascist, Clintonian, etc. don't work as well.) Capitalist economies may look random, but they are not. The look random because they have so many inputs - some 6 billion of them. They use the insight and intelligence of the whole world to work. The reason that managed economies do not work is that it uses the input of only a few. So really the difference is that capitalist economies have more intelligence behind them than managed ones.

Thank you so much for all the explanations and examples! I agree with you on the difficulty in finding true randomness; notoriously, the software function used to generate a random number doesn't. Wolfram made a note of that under the problem 10 link. The only math I've seen that would be a fair toss of the coin is Chaitin's Omega.
The research I've done thus far has focused on information theory and molecular biology and therefore my emphasis has been on algorithms. But the subject of algorithms brings in Chaitin, so I wanted to be more comfortable with the game rules and terms - to continue reading with comprehension. Thank you so very much for all your help and your patience!
To: Alamo-Girl
The only "truly random" systems (currently) seems to be based on quantum mechanics. On the other hand, one does not need "randomness" to do either probability or statistics (or physics either.) For example, Champernowne developed the number .110111001011101111000.... (in base ten though) which contains every k-bit pattern with probability 1/2^k. (One concatenates the integers.)

Really? So I am sure you know the explanation of how a species can scientifically change its mode of reproduction WHILE CONTINUING TO REPRODUCE. Specifically you should be able to explain how mammalian reproduction scientifically arose by random stochastic mutations from reptilian egg layers.You, as usual, completely ignored my other points. So I will state them again. I want you to address these issues, not the issues you want to address. I've also added in new ones, and as you are so fond of repeating the same 5 questions over and over again, as will I until you address them. The answer to your question above lies in one of them:
Because parts of a theory cannot be explained yet, does this immediately disprove a theory? A theory being a model of the universe, or a restricted part of it, and a set of rules that relate quantities in the model to observations that are made. Asking a theory to explain a certain aspect of the model, which the theory cannot explain as of yet, does not mean that the entire theory is debunked. When Newton's theory could not explain the the motion of Mercury exactly, but was close, was it thrown out? No. Einstein's model answered many of the questions about the errancy of the Newtonian model.
Evolution does not necessitate atheism. I can prove it right now. I am creating a religion (although it is not real, it makes me a theist regardless) which states that the universe was created and my God created the first life (abiogenesis not being a tenant of evolution). God then set forth a process called evolution which He knew with infinite wisdom would eventually create an intelligent enough being to worship Him. Say what you will about the lunacy of this religion, it is a religion nonetheless (plus I will claim that you are a B. Rabbiticism basher if you do). I just called my buddy and he said he will convert to my new religion, so I officially have a following. A similar process is done by real religions around the world and has been loosely declared by the Pope...
NEW POINT #1 (related to above point): Some people also believe in the morality, story, and ideas behind the Bible. However, they also believe that man (multiple men)had a part in its creation and therefore mistakes were perhaps made. Therefore, many Christians recognize this possibility and refuse to throw the baby (the overlying theme and beauty of the Bible) out with the bathwater (the scientific inconsistencies).
NEW POINT #2: This is for you and f.Christian and it attempts to counter the ludicrous connection with liberalism and evolution. I will prove the point by asking you a question, your answer will either show you that you're wrong or prove that you only equate conservative thinking with Christian thinking. A man explained all of his beliefs to you over a cup of coffee at Starbucks, and you learned that he was against any increase in taxation from what it is now, especially for welfare purposes. If you learned that he thought that the government was too filled with bureaucratic nonsense and needed to be slimmed down. He believed that the capitalist state is the only one which will eventually lead to a strong economy, and a strong foreign policy is essential to the protection of its people. After all this, he told you he thought that there was something to the theory of evolution, would you label him a liberal? Would you be so narrow minded?
New Point #3: I've learned a lot since joining this thread, and the following statement derives from this attained knowledge. If a large number of RATIONAL men believe something to be true, it is irrational to conclude with complete authority that they are incorrect unless you can provide absolute and compelling evidence which destroys the theory. This is true for religion, and right now, it holds true for evolution.

Sounds good to me, what shall we call ourselves, rabbitites?Yes, and I will be Rabbit-Pope I. I was going to call my 'priests' rabbis but apparently that is already being used. Do you want to be a rabbiti?
