Re: New NASA study predicts high probability of collapse of industrial civilization
I'm not sure I follow much of what you are saying here. Maybe I need to go away and sleep on it. Then again, it's hard to answer comments on your memory of another thread... One thing about 1984 is that the Party are, I think interestingly, powerless. They never let *anyone* who commits thoughtcrime go free, they are always cured and then executed. This means the Party is simply a machine that follows this pattern, with no choice in the matter.

However I suspect that your rants about how [insert special interest group here] are a bunch of [insert despised political group here] planning to create a [insert feared political system here] may not have helped people appreciate that this is your position. What's interesting about the way you write this as a fill-the-blanks template, is the question of how close your template comes to ubiquity in terms of total-humans/humans-filtering-the-world-through-lizzies- templatee At least partially filtering through the template anyway. Keeping meaningfulness by requiring instances of whole template usage, not partial. Staying with that measure, a further question would be how much more closely does your template define the contemporary era than others in history? Then, defining each era in terms of how much your template captures it, what does history look like on those terms? Does it tell a coherent story? Like, are there lizzie template spikes at the major milestones, like the French Revolution, or the Bolshevik Takeover of Russia, or during the Cold War. Would that template alone be enough to define every historical period sufficiently that each one, say, had its own distinctive template usage character. For example the Cold War might feature massive usage, but with everything breaking down into two templates in most common use. One for soviet and the other for American sympathy. Bolshevik could also be largely broken into two, one involving, say, the bourgeoisie or something. French Revolution might pair around 'aristocracy'. Thinking about it, could not the emergent pattern from history be that there is generally a reactionary and revolutionary template? A template for the incumbent and for would-be nemesis. Or in time, of the power that ruled in time going backwards and power that rules in time going forwards...around some point. The cold war template would kind of break into four..two each for East and West, such that both represent both positions. But does the contemporary situation fit the historical pattern? It seems vastly more complex to me. In all the other instances, there was major backing for the template...two elites, or one elite and one would-be elite, would be ultimate backers of one of the two mirroring templates. Everyone pretty much knew who the elites were. At least that could be said. Do we know now? What would the template usage say, keeping with the idea of that being the only information allowed to define history. Would the template usage that said knowledge of elites was fairly strong, show a division about two ways? That'd fit with historical situation. What about now? Fair enough history must have had some outlying daft theories like now, so let's elimate those. Also control for the information revolution and the extents, then, of templates becoming more complex due to people being influenced online. One way to do this would be to select a sample of the most mainstream template. Surely most of us have some experience of the mainstream. Either we're moving in the direction of it, or moving the other way. But generally we know something about it. Does the mainsteam template know who our elites are right now? Do you? Do people even here in this thread agree on this question? How many different views on this are here alone? It's a world of infinite infinities, bocktime multiverses, endless potentials and exponentially growing optimism...where to say otherwise is literally bad philosophy by definition. There is even the suggestion that elites cannot exist at all...not cohersive ones anyway..,that to say otherwise is bad philosophy too (i.e. Deutsch). Maybe that's a reason why no one knows. Because no such thing exists. Maybe the reason fewer and fewer people talk about such a thing as an incumbent elite. Fewer news references, fewer political references, fewer

Quite so, but you were making a completely invalid leap of reasoning from your sense data - something along the lines of I see birds singing in the trees, so mass species extinction is humbug. That is obviously fallacious. The species extinction rate is estimated at 0.01% per annum by the WWF, so of course there is still a vast majority of species left, including those starlings out your window. 1-10K times background does not translate necessarily to a large proportion of observed species, especially in the near-monoculture inhabited by urban humans. That is just so blindingly clear and indisputable that you should really just retract that remark. This is part or the scientific endeavor as well. Observe, record, and measure, hopefully in common units, milibars, meters, kilograms, parsecs. But one must observe and try to make sense of things. Just as the oil companies say no, no, no, we pollute nothing, the environmentalists push for a common goal as well. One is driven by greed to lie, the other by a hunger for power-to save the world. Of the two sets of bastards, I have learned to mistrust the environmentalist even more so than the petro kings. Environmentalists get things wrong due to knee-jerk, party-line responses to issues - the objection to all nuclear power may be an example. But the motivation to preserve the life of all beings on this planet is always going to trump naked, short-term greed in my book when it comes to which bastard I trust. On another note, I think you have probably heard of the physical anthropological papers indicating that the paleo-south americans, did an excellent job of sustaining the rain forests, by simply doing what was in their interests. Damming streams using logs and boulders, and mud, removing natural dams in the uplands by digging using tree branches, crude shovels, their hands. I hear the (not-so) faint background anthem of right-wing ideology. Self-interest can be trusted to bring us all the best possible result. Let's all get out of the way and let the market save us all. You can bet the corporations will be building sea-walls if the ocean does start to rise dramatically, but the fact is the interests of corporations are way too short-term. CEOs care about this year's balance sheet, next year's, and maybe, just maybe the balance sheet in five years' time. Beyond their own retirement horizon they couldn't give a damn (or a dam). And corporations are enmeshed in the inertia of how things have always been done. Finally, with regard to saving the planet even at the expense of humanity, that's like talking about saving the ocean even at the expense of the fish. We are utterly dependent on the health of this planet. Certainly there are real tensions between environmental and human concerns - do we let community X clear-fell a certain forest? If we don't the community will suffer economically. But ultimately if we let every community log every forest at will, we will end up with an atmosphere that can't regenerate its own oxygen supply. Those Amerindians couldn't do too much damage through their self-interested actions precisely because they only had their hands and a few primitive tools. It's the power of modern technology that is the game changer. We can't be one-sidedly environmentalist and just ban all logging. Rather we need to work with the tension of these competing concerns and use all our human ingenuity to find technical and social solutions to these immensely challenging problems. The world is complex - no simple-minded ideology like trust the market is likely to hold the answer.

Photograph: AFP/Getty Images A new study sponsored by Nasa's Goddard Space Flight Center has highlighted the prospect that global industrial civilisation could collapse in coming decades due to unsustainable resource exploitation and increasingly unequal wealth distribution. Noting that warnings of 'collapse' are often seen to be fringe or controversial, the study attempts to make sense of compelling historical data showing that the process of rise-and-collapse is actually a recurrent cycle found throughout history. Cases of severe civilisational disruption due to precipitous collapse - often lasting centuries - have been quite common. The research project is based on a new cross-disciplinary 'Human And Nature DYnamical' (HANDY) model, led by applied mathematician Safa Motesharri of the US National Science Foundation-supported http://www.sesync.org/ National Socio-Environmental Synthesis Center, in association with a team of natural and social scientists. The study based on the HANDY model has been accepted for publication in the peer-reviewed Elsevier journal, Ecological Economics. It finds that according to the historical record even advanced, complex civilisations are susceptible to collapse, raising questions about the sustainability of modern civilisation: The fall of the Roman Empire, and the equally (if not more) advanced Han, Mauryan, and Gupta Empires, as well as so many advanced Mesopotamian Empires, are all testimony to the fact that advanced, sophisticated, complex, and creative civilizations can be both fragile and impermanent. By investigating the human-nature dynamics of these past cases of collapse, the project identifies the most salient interrelated factors which explain civilisational decline, and which may help determine the risk of collapse today: namely, Population, Climate, Water, Agriculture, and http://www.theguardian.com/environment/energy Energy. These factors can lead to collapse when they converge to generate two crucial social features: the stretching of resources due to the strain placed on the ecological carrying capacity; and the economic stratification of society into Elites [rich] and Masses (or

Jesse: You think in classical statistical mechanics there can't be 2 different ways to get to a given *macrostate*??? If so you are badly confused. And I'm the one who is supposed to be confused??? There is not one drop of Quantum Mechanics or probability in the Game of Life, it is 100% classical mechanics, and yet there CAN be 2 or more ways to get to a given macrostate. It's 100% deterministic so if I show you a Game of Life pattern you can calculate what it's future evolution will be (there doesn't seem to be anything analogous to chaos in the Game) but you can't figure out it's history was, or at least not a unique history. Today the deepest understanding of entropy comes from the study of Black Holes. From: http://www.phy.olemiss.edu/~luca/Topics/bh/entropy_origin.html S [entropy ] is the log of the number of quantum mechanically distinct ways that the black hole could have been made, or information lost in the creation of the black hole Are you suggesting that this new deep understanding invalidates the older understanding of entropy as the number of microstates for a given macrostate, the one you yourself quoted in your last post? I am saying that Kip Thorn, one of the world's best physicists, wrote on page 446 of his book A Black Hole's entropy is the logarithm of the number of ways that the hole could have been made. And I'm saying that in classical physics a state can produce only one future state, but any given state can have been produced in more than one way, therefore the number of microstates in a Black Hole must equal to k times the number of states that made it where k is some constant integer. Therefore if Entropy is proportional to the logarithm of the number of microstates in a system then according to the laws of logarithms Entropy MUST also be proportional to the logarithm of the number of ways the system could have been produced. Assuming the unitary nature of quantum mechanics is preserved so that information is not lost when things fall in [into a Black Hole] That is quite a assumption, today it's one of the greatest controversies in physics and nobody knows if that assumption is valid; see Leonard Susskind's book The Black Hole Wars. the number of quantum microstates that any macrostate can have NOW must be the same as the number of initial quantum microstates in the PAST which would have led to the current macrostate, so the number of distinct ways it [the current macrostate] could have been made would be exactly the same as the number of distinct quantum microstates it could be in now So why in hell do you say Entropy is proportional to the logarithm of the number of microstates something can be in and still have the same macrostate, but it is not proportional to the logarithm of the number of ways the thing could have been produced? in practice, I think almost any real-world experiment you could do in an elevator in free fall in deep space wouldn't show any divergence from the predictions of special relativity that would be measurable by modern equipment. Not true. As far back as 1963 it was noticed that clocks tick slower on the first floor of the physics building at MIT than they do on the second floor, Special Relativity had no explanation for this but General Relativity did, clocks on the first floor were closer to the center of the Earth than those on the second floor and thus were in a stronger gravitational field and thus ticked slower. And today the standard GPS receiver in your car must synchronize it's internal clock with the clocks in 3 or more navigation satellites, to do this it must take into account some pretty exotic things; for example, the satellite is moving very fast so due to Special Relativity the satellite's clock will LOSE 7210 nanoseconds a day, but the satellite's clock is in a weaker gravitational field than the clock in your car because it is further from the Earth's center, so due to GENERAL RELATIVITY the clock will GAIN 45850 nanoseconds a day. Taking these 2 factors into account the satellite's clocks gains 45850 -7210 = 38,640 nanoseconds a day relative to the clock in your car. If your car GPS receiver

It's 100% deterministic so if I show you a Game of Life pattern you can calculate what it's future evolution will be (there doesn't seem to be anything analogous to chaos in the Game) but you can't figure out it's history was, or at least not a unique history. Today the deepest understanding of entropy comes from the study of Black Holes. From: http://www.phy.olemiss.edu/~luca/Topics/bh/entropy_origin.html http://www.phy.olemiss.edu/%7Eluca/Topics/bh/entropy_origin.html S [entropy ] is the log of the number of quantum mechanically distinct ways that the black hole could have been made, or information lost in the creation of the black hole Are you suggesting that this new deep understanding invalidates the older understanding of entropy as the number of microstates for a given macrostate, the one you yourself quoted in your last post? I am saying that Kip Thorn, one of the world's best physicists, wrote on page 446 of his book A Black Hole's entropy is the logarithm of the number of ways that the hole could have been made. And I'm saying that in classical physics a state can produce only one future state, but any given state can have been produced in more than one way, therefore the number of microstates in a Black Hole must equal to k times the number of states that made it where k is some constant integer. Therefore if Entropy is proportional to the logarithm of the number of microstates in a system then according to the laws of logarithms Entropy MUST also be proportional to the logarithm of the number of ways the system could have been produced. But Kip is speaking loosely. If you look at the original paper with Zurek http://journals.aps.org.proxy.library.ucsb.edu:2048/prl/pdf/10.1103/PhysRevLett.54.2171 you see that they are counting up the number of states by imagining adding quanta of energy as small as possible at each step to building up a black hole. But this is just a way to aid the counting, the result has no dependence on the imagined order. It's just a way to calculate the number of internal states consistent with the macro-states of the no-hair theorem. Assuming the unitary nature of quantum mechanics is preserved so that information is not lost when things fall in [into a Black Hole] That is quite a assumption, today it's one of the greatest controversies in physics and nobody knows if that assumption is valid; see Leonard Susskind's book The Black Hole Wars. the number of quantum microstates that any macrostate can have NOW must be the same as the number of initial quantum microstates in the PAST which would have led to the current macrostate, so the number of distinct ways it [the current macrostate] could have been made would be exactly the same as the number of distinct quantum microstates it could be in now So why in hell do you say Entropy is proportional to the logarithm of the number of microstates something can be in and still have the same macrostate, but it is not proportional to the logarithm of the number of ways the thing could have been produced? in practice, I think almost any real-world experiment you could do in an elevator in free fall in deep space wouldn't show any divergence from the predictions of special relativity that would be measurable by modern equipment. Not true. As far back as 1963 it was noticed that clocks tick slower on the first floor of the physics building at MIT than they do on the second floor, Special Relativity had no explanation for this but General Relativity did, clocks on the first floor were closer to the

Natural and social scientists develop new model of how 'perfect storm' of crises could unravel global system This Nasa Earth Observatory image shows a storm system circling around an area of extreme low pressure in 2010, which many scientists attribute to climate change. Photograph: AFP/Getty Images A new study sponsored by Nasa's Goddard Space Flight Center has highlighted the prospect that global industrial civilisation could collapse in coming decades due to unsustainable resource exploitation and increasingly unequal wealth distribution. Noting that warnings of 'collapse' are often seen to be fringe or controversial, the study attempts to make sense of compelling historical data showing that the process of rise-and-collapse is actually a recurrent cycle found throughout history. Cases of severe civilisational disruption due to precipitous collapse - often lasting centuries - have been quite common. The research project is based on a new cross-disciplinary 'Human And Nature DYnamical' (HANDY) model, led by applied mathematician Safa Motesharri of the US National Science Foundation-supported National Socio-Environmental Synthesis Center, in association with a team of natural and social scientists. The study based on the HANDY model has been accepted for publication in the peer-reviewed Elsevier journal, Ecological Economics. It finds that according to the historical record even advanced, complex civilisations are susceptible to collapse, raising questions about the sustainability of modern civilisation: The fall of the Roman Empire, and the equally (if not more) advanced Han, Mauryan, and Gupta Empires, as well as so many advanced Mesopotamian Empires, are all testimony to the fact that advanced, sophisticated, complex, and creative civilizations can be both fragile and impermanent. By investigating the human-nature dynamics of these past cases of collapse, the project identifies the most salient interrelated factors which explain civilisational decline, and which may help determine the risk of collapse today: namely, Population, Climate, Water, Agriculture, and Energy. These factors can lead to collapse when they converge to generate two crucial social features: the stretching of resources due to the strain placed on the ecological carrying capacity; and the economic stratification of society into Elites [rich] and Masses (or Commoners) [poor] These social phenomena have played a central role in the character or in the process of the collapse, in all such cases over the last five thousand years. Currently, high levels of economic stratification are linked directly to

The species extinction rate is estimated at 0.01% per annum by the WWF, so of course there is still a vast majority of species left, including those starlings out your window. 1-10K times background does not translate necessarily to a large proportion of observed species, especially in the near-monoculture inhabited by urban humans. That is just so blindingly clear and indisputable that you should really just retract that remark. This is part or the scientific endeavor as well. Observe, record, and measure, hopefully in common units, milibars, meters, kilograms, parsecs. But one must observe and try to make sense of things. Just as the oil companies say no, no, no, we pollute nothing, the environmentalists push for a common goal as well. One is driven by greed to lie, the other by a hunger for power-to save the world. Of the two sets of bastards, I have learned to mistrust the environmentalist even more so than the petro kings. Environmentalists get things wrong due to knee-jerk, party-line responses to issues - the objection to all nuclear power may be an example. But the motivation to preserve the life of all beings on this planet is always going to trump naked, short-term greed in my book when it comes to which bastard I trust. On another note, I think you have probably heard of the physical anthropological papers indicating that the paleo-south americans, did an excellent job of sustaining the rain forests, by simply doing what was in their interests. Damming streams using logs and boulders, and mud, removing natural dams in the uplands by digging using tree branches, crude shovels, their hands. I hear the (not-so) faint background anthem of right-wing ideology. Self-interest can be trusted to bring us all the best possible result. Let's all get out of the way and let the market save us all. You can bet the corporations will be building sea-walls if the ocean does start to rise dramatically, but the fact is the interests of corporations are way too short-term. CEOs care about this year's balance sheet, next year's, and maybe, just maybe the balance sheet in five years' time. Beyond their own retirement horizon they couldn't give a damn (or a dam). And corporations are enmeshed in the inertia of how things have always been done. Finally, with regard to saving the planet even at the expense of humanity, that's like talking about saving the ocean even at the expense of the fish. We are utterly dependent on the health of this planet. Certainly there are real tensions between environmental and human concerns - do we let community X clear-fell a certain forest? If we don't the community will suffer economically. But ultimately if we let every community log every forest at will, we will end up with an atmosphere that can't regenerate its own oxygen supply. Those Amerindians couldn't do too much damage through their self-interested actions precisely because they only had their hands and a few primitive tools. It's the power of modern technology that is the game changer. We can't be one-sidedly environmentalist and just ban all logging. Rather we need to work with the tension of these competing concerns and use all our human ingenuity to find technical and social solutions to these immensely challenging problems.

Further all such processes will be implemented in any universe in which they are possible. Since entropy has a fixed maximum in a closed system (a universe) then life must enable its own extinction.

And on a more practical level we are many orders of magnitude from the maximum. then life must enable its own extinction. Enable is vague. All of life on Earth would be wiped out by a nearby gamma-ray burster; but life on Earth did nothing to enable that.

I'm told (mainly by PCW Davies iirc) that the maximum entropy in an expanding universe increases indefinitely. This is how a big bang fireball that was more or less at thermodynamic equilibrium could turn into a universe full of dissipative systems. This may not however prevent life from enabling its own extinction (at least in the very, very, very long run) - although I'd say at the present epoch it is mainly stars that are enabling its extinction.

Therefore entropy in such a universe can not exceed 100% of this energy being unable to do work. That seems a max limit to me. The increase in the entropy ceiling is caused by expansion of the universe. This effectively increases the potential energy of its constituents. This would still reach some maximum in a universe without dark energy, however, note that the vacuum energy thought to be accelerating the expansion of the universe is constant per unit volume, and so the amount of it increases indefinitely in an expanding universe. Although it may not be harnessable by life or other entropic systems. More to the point, our best cosmology models give a value of precisely zero for the total mass-energy of the universe. This is because the mass-energy we see is exactly balanced by the negative gravitational potential energy. So an expanding universe should give rise to increasing maximum entropy, but the total energy remains constant (at zero). As for what happens to the free energy (stuff available for work), its a bit more complicated, but it appears that processes reducing the free energy (or increasing the entropy, as its the same thing) are not currently keeping up with the increase in maximum entropy caused by an expanding universe. -- Prof Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Professor of Mathematics hpco...@hpcoders.com.au University of New South Wales http://www.hpcoders.com.au -- You received this message because you are subscribed to the Google Groups Everything List group.

RE: New NASA study predicts high probability of collapse of industrial civilization
From: everything-list@googlegroups.com [mailto:everything-list@googlegroups.com] On Behalf Of spudboy...@aol.com Why is it that the Koch's figure so highly in your focus of vilification, but George Soros dies not? Why is political meddling by one side gets targeted but the other doesn't. You seem to have a decided preference for certain billionaires, rather then have a mistrust of all. The Koch brothers are the principal financiers of the climate change skeptic think tanks – it seems clear they are motivated to do so by a desire to protect the future valuation of their considerable coal reserves.. a major component of their vast holdings. It is not the Koch brothers per se, but what they are backing and funding and how they are seeking to influence public policy in ways I oppose and that I feel are highly detrimental to our future survivability as a species and as a culture. When have I ever voiced support for George Soros, since you accuse me of doing so? Show me a single example. You can’t because I haven’t. There are a many billionaires I do not mention specifically because they are not funding a astroturf movement – that is organized similar to and in fact staffed by many of the same propagandists who worked so hard for so long to discredit the science linking tobacco use and the many diseases now known to be caused or exacerbated by it. You say so many things without backing them up with facts. Please show me some examples of my alleged support for Soros; if you cannot I wonder if you have the courage to admit your error.

If you have some actual science based reason to criticize this study, by all means share it with us. But you don’t do you – you have not even bothered to read it now have you? Be honest. Your rebuttal of the NASA study is sorely lacking in scientific rigor, preferring instead to rely on a series of colorful adjectives to present your case. If you are such a lover of science then use science and scientific data, and arguments based on clear deductions from that data to try to make your hypothesis.
