The Australian Moment
Tuesday, March 13, 2012
Why I am not voting Labor
In Australia we’re advancing the fine art of destroying small business entrepreneurship. In yet another attack against entrepreneurship, the Gillard government is moving to outlaw home-based business people in the clothing sector. The new law declares that self-employed clothing business people (mostly women) are employees. In this instance the death of small business is not an unintended consequence, it’s the direct stated outcome of the Gillard government’s policy.
There needs to be an allowance for a progression from home based clothing businesses, all the way to fashion warehouses. At the moment, absolutely everything in between that involves subcontracting is looked at with suspicion. Clothing businesses run from home are essentially illegal if they do work for any other businesses, or get smaller businesses to do work for them. How does any clothing business go from A (being a hobby) to B (a business employing people) legally?
The Queensland government does not directly make these rules, but determine the level of enforcement, which at this point is not doing them any favours.

Marconomic evolutionary theory
My theory of abiogenesis starts from the formation of second generation stars from remnants of supernova dust cloud intercepting a pristine Molecular cloud. Experimental evidence shows that these exist, and are likely precursors to our solar system and orbiting bodies. There is experimental evidence for molecular clouds clumping together to pristine low density snowballs. These "pristine comets" would have a density of about .2 ie. they are mainly empty space. The supernova remnant dust cloud however, would be a lot more chaotic mixture of elements. Before or after the accretion disk of the solar system formed, the border zone between the dust clouds would have had pristine comets infused with heavier elements from the supernova dust cloud. Perhaps billions of these comets would have had liquid water in them due to heat from radioactive heavier elements. Protected by a covering of snow, and kept liquid by slowly decaying elements, these "pristine comets" would have all the ingredients required for primordial soup style evolution to occur, in billions of slightly different conditions, and with mechanisms that would almost certainly exchange chemistry, collide and fragment. Every individual comet of this type would have similar probability of chemical evolution than the early Earth would. Having so many of them multiplies the probability of Precisely the right initial conditions for evolution to happen quickly.
Whether "modern comets" are anything like "pristine comets" is a matter for debate. After all, it has been 4 Billion years since we had a pristine molecular cloud near our solar system, so no matter the origin of any "modern comet", assuming it is a pristine comet relatively recently perturbed near the sun, is probably not helpful, as recent evidence appears to contradict the assertion that they are anything like pristine. The point is that early in the piece, as the solar system was still forming, lots of comet like objects had all the features required for the sorts of successful precursor evolution, and more. How far this evolution went, and where it spread from, and to, is a pertinent question to answer. There have been several successful missions to comets, and several comets have now been imaged in close detail. We have collected samples from the coma of one, a space mission will analyze the surface of another in 2014, and yet another mission will collect and return a sample from the surface of an asteroid. All observed comets have discrete jets on the surface which have stable positions from apparition to apparition. These are thought to be from fissures in the comet from which sublimating volatiles escape expelling dust out. A robot spacecraft could drop a tethered explorer into one of these fissures to look inside the comet, plausibly to a great depth, while the comet is in a dormant phase. This would generate useful information about what is happening inside the comet.

An Idea for a science fiction book
Speaking of Jets, Scientists are quite sure the jets are due to sub-surface sublimation of volatiles (water, HCN etc.) forcing out dust particles at the same time. Surfaces appear quite stable, and the jets are in static positions on the comet nucleus.
The following link for comet temple 1 demonstrates how jets on the same location of the comet sporadically ejects a sudden large amount of mass, at the same point of its 44 hour rotation period - ie. in the same direction in space. Scientists believe this is due to the uneven solar related heating related to the rotation somehow causing the random outburst. It would be a better science fiction story if these jets were an orbit correction maneuvre.
Scientific theory holds that many comets are loosely connected pieces given the long List of comet pairs and other splitting events that have been shown to occur.
It would be a much better science fiction story if these events were like amoebal fission - ie. that comets were reproducing. They may have been around for many millions of years, accreting mass through collisions. Now they have enough energy and mass that they can reproduce and go their separate ways - perhaps one might one day leave the solar system and explore other systems.

Now addicted to ResearchGate
Have found easy to access scientific discussion in a forum which reminds me completely of Facebook. It is infinitely easier to access actual research rather than just what is freely available on the net (although admittedly some researchers restrict some of their stuff)
{Non sequitur}
I am still convinced we will discover intelligent alien life within our lifetime (say before 2050) and they will be (or in) comets and not life as we know it (obviously). This is an exciting prospect for me, as I thought until early this year that it was a distant untouchable possibility - an impossible dream fit only for science fiction and fantasy novels. I look forward to it, and I am assuming nobody will believe it until it stares them in the face (or into the robotic spacecraft's sensor). For that reason it will take a while. I don't feel I need to do anything about it, and just let "science" take its course. Comets have, at any rate, been found to be more interesting than suspected, and they take less rocket energy to liaise with, so will continue to be visited as a group more often than any particular planet or moon. Anyhow - you heard it here first.

Conservation of information
From the information is physical -> Szilards Engine.
The global entropy is not decreased, but information to energy conversion is possible..
This appears to put information on an equal footing as mass or energy, in the sense that it is conserved in general, but can be also transformed between energy and mass. It is tempting to follow the lead of the ID ers to intimate that informational entropy can either stay the same and increase but not decrease - My view is different, in that I believe that information can be generated through the use of energy in naturally occuring metabolic systems. .
My first postulate is that information can increase (be created) within a boundary if the entropy is increased outside the boundary..
My second postulate is that some of the energy within the boundary must necessarily increase the information if entropy is increased outside the boundary. This would mean that stars like the sun, that send a lot of waste heat outside of itself, are becoming more ordered on the inside, in proportion..
Thus random processes could not increase information, but metabolic processes can, by separating where the information is stored and expelling its increasing entropy to where it isn't..
To destroy information, the directionality of increased entropy must be directed back to within the boundary (making the rest of the universe slightly more ordered).
Neither the generation, nor the destruction of information is a perfect process, and there will be some leakage of energy to information..

Chemical factory model of "physical cemistry" life
Saturday, February 04, 2012
Where did that prebiotic life go... I know I left it here somewhere
thus the idea that prebiotic chemistry would just be absorbed into biotic chemistry when evolution had reached that level, was born. I must admit that it appears self evident. However, I can imagine progressions of events that would indicate completely the opposite- ie, that in the environment that life evolved/developed, not only would biota not destroy per-biota, but would rely on its function to such an extent that it could not. Just as we could not survive if we destroyed every bit of bacteria on our body.
Oparin proposed that the "spontaneous generation of life" that had been attacked by Louis Pasteur did in fact occur once, but was now impossible because the conditions found on the early Earth had changed, and preexisting organisms would immediately consume any spontaneously generated organism.
Again, the assumption comes in that spontaneously generated organisms could not survive alongside existing organisms. The point is, since we cannot know whether this is the case or not, because we don't have the slightest idea where or when it happened, nor the exact chemical composition when it happened, we could certainly not prove it, nor even give it a probability. Perhaps parsimony which dictates that we assume life started on Earth would follow with the conclusion that, since there is not even a scrap of evidence for prebiotic evolution here, that biota had an evidence destroying capacity in that regards, much as some species can disappear without a trace. However, if one accepts biogenesis happening elsewhere, we would have to assume that we could find evidence for it at that location, even if there is also biota at that location.

I have lost faith in scientists
For instance, one would be confused for thinking that the thousands of experiments done on the origin of life on Earth have demonstrated the plausibility of life originating on Earth. Nothing of the sort has happened. ALL the experiments start with the assumption that life started here, and they concentrate on one particular tiny aspect that has to happen a particular way for life to have started here, and the proof that it happened comes DIRECTLY from the assumption - ie. we are here so it must have happened.
With chirality, almost all carbonaceous meteorites have demonstrated chirality with their organic molecules. This has been used to prove that similar Earthly chiral molecules have non-life origin, rather than the quite different *Similar Earthly chiral molecules are as much linked to life as those from Carbonaceous Chondrite Asteroids*. There is no evidence for or against living matter having been in asteroids other than this chirality evidence, which wouldn't rule it out, but retain the possibility. Racemic organics would have ruled it out.
The explanation of how the meteoric (and Earthly petroleum) organics had become chiral is based on mathematical models of carbon molecules under high pressure. It is not based on experimental evidence. It is a classic case of believing the simplified model over testing out a typical experimental observation to back up a possible working model.
A similar thing with the model of how Comet organics became chiral.

Parsimony in the historical and descriptive sciences must die for us to make any progress
We need to do what greats such as Einstein did - evidence indicates that the speed of light is constant despite a moving frame of reference - make that an assumption and see what the corollary is.
2) The Weismann barrier (preventing direct feedback from the environment back to DNA)
Some of the conclusions I came up with - There is no reason to believe that more advanced forms of proto-life destroyed all evidence of previous forms because they would be considered food. All sorts of living things on Earth are considered food for other living things, but even with extinctions evidence is there all the way along the line from bacteria. The lack of evidence of prebiotic processes on Earth is evidence that they didn't happen on Earth.
Evolution on Earth needs random mutations no more than an engineer needs a dice to roll to make decisions on building something.
Pre-biotic evolution *does* need to rely on random mutations and selection, but the further along evolution goes, molecules may rely less and less on blind processes and more on features that made it a surviving self-catalytic species in the first place.
Working backwards from bacteria, cells appear to have evolved the capacity to lay dormant while frozen, and reactivate when thawed. This process is bound to have been the reason they ended up on Earth, and the prebiotic evolution must have been peppered with situations in which this gave a crucial competitive advantage.

Comets, astrobiology, the origin of life
He doesn't go to the extent I have of thinking how far chemical evolution has gone in comets, whether an RNA world or DNA world could exist in a comet, and think why would it stop evolving? If it hadn't stopped, it may have got to a point where the proto-life in the comet may act in a way that may increase the chance of the "survival" of the comet, in the kind of attrition where comets are gradually getting absorbed into planets with hostile environments. Could actions by the proto life make it more likely for the comet to split up into two, where one of the fragments would be more likely to survive than if it hadn't split? Could chemical or biological action by the protolife make the outside of the comet black? Would that give the comets an alternative energy source for the middle of the comet to stay liquid (the original source being decay of Al 26 or otheer elements)? Could the emmission of particles from the gaps in the black exterior serve as ways to control the spin of the comet, or even course corrections (to avoid planets, or to get close enough for a gravity assist)? Could the emmission of particles get rid of unhelpful chemicals in a kind of metabolism?
In other words, if we can see evolution working in the environment on Earth that leads to eventual intelligent behaviour due to the needs of survival, why wouldn't this be the case for comets?
Principally, is there any evidence that the two most obvious features of life are plausibly existing for comets? That is, do they reproduce? Do they metabolise? Certainly, there is plenty of evidence that they "break up". How could we tell whether this is similar to a living cell breaking up, or a non-living rock breaking up? For metabolism, how could we tell whether the outgassing is making the outside more random and making the inside of the comet more ordered? Is it plausible that it is just outgassing a random selection of compounds that make up its interior? Could it be that it is metabolism regardless of whether the comet is a living thing?
The very high resolution images of Hale Bopp combined with ground observations of the spin and emission profile, may give us some ideas on splitting comets. The rate of rotation is not constant, and the axis of rotation is such that the two ends of the peanut shape may pull apart if it spins up to a fast enough speed. The change in rotation has been determined to be from the activity of the jets streaming out more in one direction than the other. From ground observations, the spin-up is more efficient than the spin-down. The conclusion is that the comet will eventually break up due to the centrifugal forces therein. It doesn't take much imagination to feel that it could be a rudimentary reproduction similar to amoebas.

Comet Origins II
It would appear that the ejection of matter of comets would satisfy one requirement of metabolism - that of making the surroundings more random. One can assume that the inside may thus become ordered and enable complexity. The edge of the comet nucleus is an analogue of a cell membrane - it lets randomness out, and importantly, can let energy in. Solar energy is absorbed by the low albedo, and any particle or clump of radioactive material would melt the snow due to its related heat, and enter into the protected part under the snow, helping to keep the water liquid, and perhaps to help power the metabolism also.
Chemical energy, would be stored analogously to life as we know it, in sugars and various other chemicals. Of course, if there is a central control to consciously pilot the comet to its future direction and gravity assists and reproduce, it needs a brain. Surely DNA, would be the brains rather than a reproductivity code, although it would need to reproduce as well.
As well as a brain, for the other observed features of "steering" requires thrust for both rotation and course adjustments, an eye/eyes to pinpoint its precise location and trajectory, and a communication/nervous system to control devices.
For the observed reproduction/ splitting, first the nucleus of the comet nucleus,ie. the heavy elements in the middle have to split up and move to opposite ends of the liquid centre. Then the comet would have to rotate around an axis such that centrifugal forces can stretch the shape. Finally, a snow fill in between the two sides for new walls, and then have two loosely connected comets until it goes close enough to a planet for tidal forces to pull the two halves away from each other and make their orbits different.

Comet origins
Proximally, the comets are following the laws of gravity fairly precisely, barring a few exceptions of non-gravity accelerations. Tracing back and forward, it is often hard to predict past certain points where they invariably go past large planets. With robotic spacecraft, these are called gravity assists, and they save a lot of power, but require very precise calculations because a small error can send the craft into the planet or shuttling off in a helpless direction. Therefore, although the orbits, and even the breakup into families etc. is individually explainable, the overall picture of comets appears very contrived, trajectory wise. From the semi stable orbits they are in (Oort Cloud, Scattered disk, Kuiper belt, Jupiter group, Sungrazer), random interactions, perturbations or collisions would be *expected* to send them on a collision course, or to a trajectory from whence they cannot get back to one of the semi stable orbits possible.
With the discovery of CAI's from comet's coma as captured by stardust in 2006, the prospect that radioactive aluminum with a half life of half a million years was likely to have been intercepted by pristine comets, have increased the expectation that a fair percentage of comets had liquid three dimensional lakes for at least millions of years. I don't think it is a stretch to surmise that since CAIs are almost certain to be directly from a supernova remnant dust cloud, and proximally from the accretion disk of the forming sun, that heavy elements could also have made their way from the same general source to the comets or molecular clouds. The dirty snow simulations done in the lab generate aggregate that has a density of about .2. Comets with known density have a density closer to .6, so although the outside coating may be low density fluffy dirty ice, the centre is more likely to have a liquid, or formerly liquid, more dense material.
Comet 103P/Hartley gives me an impression that it is made up of two sections with a smooth neck in between. It would seem plausible to me that the comet will eventually break up into two comets, both of which have a very dark exterior with subsurface ice and certain gaps in the dark exterior. Could it be classed as reproduction? Several other cases of relationships between comets with quite different current orbits can be traced back to a common speed, trajectory, and point in space and time.
Assuming a time that comets had liquid water, autocatalytic cycles of the kind where various autocatalytic species would be competing for substrate would occur within the liquid portion, protected from ionizing radiation. The outer snow hull would serve to insulate from ionizing radiation, and also to protect from more minor impacts. These impacts would not directly affect or stop any delicate chemistry, but would supply more substrate. Hot dense materials intercepted would work their way to the gravitational centre, while low density matter may add to the bulk of the protective shell. Freezing and melting cycles (assuming elliptic orbits, solar heating would vary dramatically between perihelion and apehelion) would be a natural form of chromatography - separating different organic chemicals. Nuclear particles from beta decay would also have an affect on the chemistry.
It would be an expectation that the chemistry would continue to evolve, and not have a limit of say an RNA world or single cell organisms. DNA could coexist fairly loosely with RNA, single cell organisms and various bases, enzymes, proteins etc. Chemical evolution and biological evolution could happily coexist while the centre stayed liquid. If Earth is considered a perfect environment for higher animals to evolve, the inside of comets should be even more perfect. It wouldn't be just a possibility that evolution could go on to well past the sophistication of Earth's evolution, but an actual *expectation*.

Marconomics on Life origins and evolution 101 - Reject Ockham's Razor
Reverse Ockham's razor and replace it with Mahkco's bag of 50 disposable ones.
This is critical with the historical sciences especially, and not really relevant for physics at all. Basically with quantitative models where calculations yield repeatable results one should certainly pick the simplest model which makes the numbers work precisely. Not only that, but any new theory which complicates a model of this nature needs to have a heap of evidence and the burden of proof is against the new, more complicated theory. In these cases we should be Jack McCoys - It's not what you know, it's what you can prove. This is Ockham's Razor, or parsimony.
With historical sciences evidence is scattered in time and space compared to the "experiment" (ie. nature has done the experiment for you, but it cannot be repeated precisely to check or "prove" anything), so Ockham's Razor is a cut too deep. Not to mention that the "simplest" explanations of all often involve God, or at least an explanation that relies on faith, because by their nature the hardest questions of history have the least incontrovertible evidence. With these questions we *constantly* need to be detectives. We follow our hunches - we need a gazillion of them. EVERY scrap of evidence, no matter how circumstantial, no matter whether it is something that shouldn't be there, that is, or something that should be there that isn't, peculiarities even if they appear to be random peculiarities. These should be only weeded *roughly*. We rule out any that are impossible based on naturism, mathematical probability etc. *Not ones just because they are impossible to prove or have no direct evidence*. We need to be Sherlock Holmes, not Jack McCoy. We don't keep looking for something in a particular spot because that is where the light is shining - we need to feel our way in the dark and glean complex enough theories that make the tiniest scraps of circumstantial evidence meaningful probability-wise. We cannot stick with one theory because it is the simplest and has the most provable elements. We need a dozen, more complicated, theories that fit the circumstantial evidence in the middle of their probability range.

First of the Believers of intelligent beings in comets
Mysterious discoveries:
1) comets, although mostly water ice appear to be covered in a thin coating of very dark black carbon soot. Not predicted. Origin completely unknown.
2) Stardust samples from the corona included minerals that formed at extremely high temperatures, that were predicted not to be in comets, due to the mineral origin requiring 1000+ degrees C, and the Oort cloud never being subjected to anything like that.
3) DNA bases were also found in the stardust indicating that they were ejected from the comet.
4) Minerals were also found on one of the comets that indicated there must have been liquid water in the comet.
5) Gaps in the carbon soot layer, were evident when comet has a corona. Having a look at the picture they looked like bright circles in the dust layer with the ejecta shining through, on either side of the comet,.
6) Comet surface almost perfectly dry, yet not far under the surface is mostly water ice.
Anyway, there is more but it made my imagination go wild with possibilities.

Chapter 5 Lennox Dissection
Friday, January 06, 2012
Dissecting God's Undertaker, by Lennox via FB
The view that Lennox takes on Galileo on several pages including this one, is quite biased and misrepresents religion's role in the affair. The Catholic church at the time was using religion as a way to keep power and control information and embedded Aristotleanism into its Theology. The challenge Galileo was making was clearly against the authority of the church. It is quite plausible that he wasn't at all religious himself, but he would have had no choice other than to claim he believed in God.
Winston Inabox
I've got no idea why Lennox would even try to claim the nonsense that he claims in this Myths of Conflict section in Chapter 2. The Catholic Church's role in stifling Galileo's ideas is well documented, and it matters naught if the opposition was first from secular philosophers or not. It was the Church who put him on trial, it was the Church who put him under house arrest, and it was the Church who banned publication of his ideas. And then to say that Galileo believed in the Bible like it's some kind of proof of God's existence is just one of Lennox's many appeals to authority. Oh... OK... Galileo believed in the Bible, so it must be right! Case closed. What utter nonsense. Galileo's religious convictions - and I don't know if he was religious as Lennox claims, or just not at all - matter for nothing as evidence. What I do know is that Galileo got some things right and other things (the motion of the tides) wrong. For a man of Lennox's obvious intellectual powers this part of the book is embarrassing. 15 hours ago · Like.

There are reasons to believe the primary cause of conflict between science and religion have nothing to do with the belief in God, but he did not address that directly. Galileo had taken away the specialness endowed on humans by being at the centre of the universe. 3 hours ago · Like.

Lennox relies a lot on "This famous scientist believed in God" as being evidence that should be accepted as "forensic". There are two problems with that 1. What a person wrote as what he believed is not necessarily what they believed. 2. Believing something that is even a little bit immune to repeatable experiment or visual evidence doesn't have any baring on the likeliness of it being true, no matter how rigorous the person is scientifically. I am kind of directing this towards Nathanael Small. The Myths of conflict section does not ring true with either the atheist or the agnostic. It may well be directed at the uncommitted or the loosely committed or doubting churchgoer. It is worth reading up about the Galileo affair oneself on a neutral media such as Wikipedia to get an impartial picture. 9 minutes ago · Like.

P31 Thanks for the photo Marco. Lennox, because he's mostly running a negative campaign, always tries to show there is some discord. It doesn't help his point, he just tries to make it look like science should be doubted, that it doesn't ha...
Now rather than going back and modifying his definition to one that would include cosmology, he instead runs off with the 'method of inference' which he says is "an essential part of the methodology of contemporary science". This allows him to claim that "with unrepeatable events it is still possible to ask: What is the best explanation of this event or phenomenon?"
In other words he's softening the reader up to later accept that although the creation of the universe is unrepeatable, science can possible say that a god did it.

Marco, the above shows that Lennox is quite adept at rhetoric. Everything he says seems logical because he is very careful about about making only small claims that on the surface seem reasonable, that are then built up to make his point.

Now I wouldn't normally care less if he were just stating his opinion, but he then uses this opinion as fact to imply that there is difficulty in defining scientific method, so let's use Ruse's definition, Ruse's definition uses repeatability, but repeatability excludes cosmology which is obviously science, so let's go to method of inference, so that allows the inference of a god in the creation of the universe.

Although procedures vary from one field of inquiry to another, identifiable features distinguish scientific inquiry from other methods of obtaining knowledge.
Your sentence that follows this is an example of an identifiable feature that distinguishes scientific inquiry from other methods of obtaining knowledge. As is the rest of the paragraph.
Lennox however doesn't want to inform his readers that "procedures vary from one field of inquiry to another". He'd rather focus on the non-repeatability of aspects of cosmology because he wants to introduce method of inference.
