Re: [FRIAM] Assistance sought: The meaning of constraints
[my comment follows Russ's] Russ Abbot writes: As I understand it, work is defined as the change in kinetic energy resulting from the application of a force. Normally that means work is force times distance. So if there is no distance (no motion) there is no change in kinetic energy and hence no work. A tug-of-war between two absolutely balanced teams results in no work even though both sides are pulling as hard as they can. But is that what you are really interested in? That gets us somewhat far afield from a more general notion of constraint. Perhaps it would be helpful if you would clarify what you care about in this context. In what it is that Nick cares about, is there *any* reason to believe that there is *any* conservation principle for *anything* (in his system[s] of interest) that plays a role like that of energy? Only if there is such a principle, it seems to me, is there any principled way for him (or you or us or me) to distinguish some analogues of kinetic energy and potential energy; and (again, as it seems to me) without an analogue of kinetic energy (principled or not), the definition of work from physics (that you quote above) begins to drift into inanaloguizability even before we tax it by asking what's 'force' in Nick's context? (already under discussion), much less what's distance/motion in Nick's context? (only recently mooted).

Re: [FRIAM] Work! Fer Gawd and Newton's sake!
In the true spirit of FRIAM, I propose that we generalize what we mean by generalize. And then we could perhaps steer the discussion in the direction of how to produce a generalizable ABM. Said ABM could be made aware of it's computing host, therefore further generalizing its computation capability, accordingly. (Depending on what was meant by computation, of course).

Re: [FRIAM] A modest proposal
Oranges and Apples maybe? They're different technologies (BWR vs PWR). It does not appear that any of the current issues at Fukushima originated with the basic design, but were due to loss of supporting infrastructure (e.g., loss of grid power to the pumps, the wave washed out the diesel backups). It would be lot cheaper to harden the backup power and do various other safety mods.Eventually you'll want to retire the BWRs and PWRs because they'll become more expensive to operate than alternatives (including Gen IV nuclear and possibly other non-nuclear). I don't know how long it would take to the alternatives up and running but it has to get done before 2025 when the licenses for the current plants run out. Decommissioning one of these Gen II reactors is not just a matter of flipping a switch; it takes some years to happen (remember those nice spent fuel pools).

If you read the Wall Street Journal, then you get the impression the situation is not that bad at all, it is only unconfortable for Tepco (Tokyo Electric Power Company). If you follow the media and read the newspapers here in Germany, you get a completely different opinion. You get the impression that this is the worst atomic crisis since Chernobyl. This is what the people wanted to hear, because the majority of people in Germany is against power from nuclear power plants. I guess it started with the Chernobyl disaster, which affected Western Europe much more than the USA. Maybe the media in the US focuses on different things, because the people want to hear something else? Or is the US nuclear industry so strong that it can influence the public opinion? I think the worries are justified, it is indeed the worst atomic crisis since Chernobyl. We have seen now for the first time what happens if an earthquake or a tsunami hits a nuclear power plant directly: from a nuclear catastrophe to a nuclear meltdown, everything is possible. We have seen in Japan how dangerous nuclear waste is (a fire broke out in the reactor's fuel storage pond - an area where *used* nuclear fuel is kept cool). I think this sheds new light on unsolved problems, since the nuclear waste problem as a whole is completely unsolved, isn't it? If it is so safe to store it, then the US could store it for others.

That being said the very few physics i've talked to have said right off theoreticly you could store spent cells just abount anywhere sighting that these days that you get more exposer to harmful radiation over the course of a cross countery plane trip than about a year of 'leaked' radiation from spent rods. IF it's politicly viable to store Japans spent rods i'd think they'd apraciat any assistance at all.

Re: [FRIAM] Work! Fer Gawd and Newton's sake!
Agreed! Work, constraint, cause, etc. were all words long before Newton (if we are willing to translate them, many centuries before). Newton gave them very technical meanings in his system, but the technical meanings were just a matter of making more strict the common meanings. We could, if we wanted to, try to find psychological analogs closest to Newton's meanings, or we could try use the looser (but related) common meanings. In either case, the short answer to Vladimyr's question is that people using these terms to talk about psychological systems want them to mean the same things they mean when talking about physical systems. So, some want them want the words to be very technical terms, others want them to carry the connotation of general usage. It should be obvious to anyone using the terms that any such usage is highly metaphorical; should be, but for some reason it is not. Beyond that, as Nick pointed out, they weren't my words of choice. Personally, I think psychology would be a lot better off if we minimized such talk as much as possible. Claims like beliefs constrain intentions seem strange and potentially vacuous to me. Even if it is not totally vacuous, the amount of intellectual work we would have to do to unpack the claim makes me think it is not worth it, and I would suspect that there was probably a much more straightforward and empirically tractable claim that the claimant could make instead (maybe something like; Past experience determines a large proportion of the variance in future actions, or verbal behavior is a somewhat reliable predictor of the way future actions will be directed). I am reminded of the long arguments psychologists have over whether some third factor is a moderator or a mediator of a known effect. Surely this is a useful distinction, but probably not one worth the amount of time and effort put into it. Further, the problem could probably be solved completely by dedicating a full sentence to the role of the third factor, rather than trying to come to consensus on magical one-word specialized terms.

Eric , Please do not disengage just yet, first. I did not know if the mysterious Writer wished to use engineering terms or to simply capitalize on Cache. It does not matter either way. The fact is the brain cobbled together all these terms long before Newton Leibniz and Descartes. So why why would it do so… It is I believe now that we experience the world exactly as through those crappy little words with no dimensions. Everywhere I look the psychological expressions people use daily are dimensionless. Why I ask. The answer seems to me to be a bit like the abacus or the Go Board . It is some kind of matrix slash image machine. It simply has no need for units as long as it remains self referential ; there is no need for zero or even numerals. It seems essential to have a memory , clock and pain, Booze and Smokes optional. So for now I suggest you have a little patience and we begin to discuss a new computational engine model without units or numbers. I was not prepared for this when I responded and we got stuck in the mud so to speak. Accidentally I gave you the concept of strain energy, also a form of work . I noticed then Force, the Newton, was a strange little beasty while everyone was ragging on Work in the classical system. But the Newton of Force is always painful for me and I actually despise the beasty, no disrespect for Newton. I thought I knew what force was when I felt it and was trained to ignore that with no success. So I looked at my past and realized I never measured Newtons in my life! I do not even think there is a Newton meter. We measure stress changes as resistance or strain, then we calculate Force only by also measuring something different such as Area. In an odd way this was revealing. I am a scientist and a shitty engineer, so I always cheated and worked with pounds because as a kid I worked in a butcher shop and could eyeball a pound of ground beef within grams. How the heck could I do that without a scale, again I must have used strain in a muscle set and a distinctive memory of the sensation at exactly 1 pound. Years later I learned engineering and all about units. Strain is just displacement and there are specialized proprioceptors with a uncanny resemblance to a standard foil type microstrain gauge. To measure two pounds I did it twice but could not accomplish it in one go. As a psychologist I would love to pick through your rubbish heap when I have time. But in principle the brain has established these engineering values in an alternative manner but self referentially. There in lies the revolution that forced us to put words to self referential concepts that did not match a little child or a 200lb plus heavy weight. To communicate we needed more fixed externalreferences, we needed universals or so it looks. Newton took some time in arriving. But we already had some in place. We universally know the sun is above and the earth below. The deer flesh is best freshly killed and water and hot go together.Without externals we get trapped as Solipsists or Existentialists, heaven forbid even romantics. I am trying to suggest that we can in theory translate bodily sensations into many of the engineering values not the other way round as initially assumed was to be the case. I hope you can support my belief that we use something like matrices when thinking or maps. Considering primitive animals have uncanny navigational equipment on board I assumed we also had similar rudimentary capabilities. Philosophically we are now faced with a multiplicity of self referential universes and a universal language under construction and a reality constantly causing havoc . Plus we have a lot of crotchety old men who think they understand everything and old ladies who are convinced we are all fools. Now occasionally the mathematics has produced unimaginable creatures such as the Newton,Currie , the Coulomb and when we look closely we notice something completely new manifest itself with no conceivable sensory equivalent. Lift for example. Somehow we learned to fly and that is very remarkable and worth a little patience and a plea for indulgence perhaps even mercy( I always ask for more than I need and settle for a little less) Thank you gentlemen and Ladies.

Work, constraint, cause, etc. were all words long before Newton (if we are willing to translate them, many centuries before).
