If you accept the idea that the causal structure of the universe puts a speed limit on light, which we call c, then you have already accepted the Theory of Special Relativity.

This does seem correct dimensionally - viscosity has units of N s m^-2, and density kg/m^3 (I prefer mks to cgs), so viscosity / density has units of m^2/s, which if you assume a unit cross section pipe gives you units of 1/s. But this is not the "flow time", (as in for flow in a closed pipe), but a "relaxation time" for viscous effects. Flow is controled by several other things, and is in general very insensitive to such slight changes in viscosity (in large pipes - in capillary tubes viscous effects become important). > What did the heat do to the water molecules to make the > molecules role over each other so much faster?

This seems to be a rather odd concept - water is a fluid, and treating it as a "cubic chunk" is something that is only done (to my knowledge) to calculate floe integrals. > Only a small fraction of the energy absorbed between 0 > C and 100 C by the water goes into raising its temperature. > Of the 1.2538E-20 Joules/molecule absorbed, 2.0710E-21 > J/molecule went for temperature as kinetic energy of > vibration and translation. > I calculate that about 1.1E-21 J went into potential > energy of expansion.

Are you refering to tubulence? This is a contribution to fluid flow, and it is influenced by the viscosity (through the Reynolds number), but I'm not sure if that's what you're talking about. -Brian Davis

With a shuttle position of X = cos t, Y = sin t. And an object position given by X+x, Y+y, we have: psi = t + e*sin t + psi_0 = t + delta , delta << 1 y+Y = sin psi = sin t * cos delta + sin delta * cos t -> sin t + delta * cos t x+X = cos psi - e = cos t * cos delta - sin t * sin delta - e -> cos t - delta * sin t - e so x -> (- psi_0 - e*sin t) * sin t - e = - psi_0* sin t - e/2 * ( 3 - cos 2t ) y -> ( psi_0 + e*sin t) *cos t = psi_0*cos t + e/2 * sin 2t at t=0, we have the initial conditions x = -e, y = psi_0 ; vx = -psi_0 , vy = e Note we have satisfied the periodicity condition x = -vy. The extra condition y = -vx just fixes the phase ( and position ) of the orbit. So all the qualitatively different orbits are included. Note that they are a combination of full period and half period motions. Note also that with psi_0 = 0, we get the "oval" orbit I described, except that the "oval" is a circle! I misread my simulator output, where y varied between +/- 0.0005 and x varied between 0.001 and 0.002. So where is this in a book? You'd think it would be. Lew Mammel, Jr.

[discussion of how measurements by diferent observers vary according to their relative speeds] You say "absolute", yet every example you give is of the effects of relative velocity as used in relativity.

Claiming that "Cogito, ergo sum" is guilty of petitio principii is not really accurate. As Kant pointed out, the argument fails because "exists" cannot be regarded as a predicate.

It >is carefully chosen, and reflects substantial thought on what science >is all about. Further defense of it I leave to Mati. Thank you. I'll try to clarify a bit. It ties to what I wrote about the issue of generalizations and why a generalization may be a revolutionary act even though looking backwards there seems to be a smooth path leading from the old to the new. The key issue is that generalizations are by no means "obvious". You reach a point where you can't just keep developing previous ideas, a decision is needed. Sort of "mental crossroads". And it may not be obvious at all, a priori, which path to pick. That's the point where the "touch of genius" is needed. So, before it seems that I go to far off on a tangent, to me a new theory begins at such a "branching point" where decisons are made and new concepts and ideas introduced (or, possibly, previous concepts acquiring a quite different meaning). With Newton, the Three Laws are such a point (in physics, then you could separately point to calculus in math), there is no doubt that there you witness the birth of a new theory. OK, so how about gravitation. Once the laws of motion were there, what else was needed. An assumption that the planetary orbits have something to do with some force? Yes, but Newton was already committed to the idea that any motion where the velocity changes (i.e. specifically, any orbit) is the result of some force. An assumption of universality? Yes, but Newton was already committed to universality too, his laws were already stated as universal, not something valid only in Southern England. So, there was no need for new assumption or ideas, only taking the ideas that were already embodied in the laws of motion and applying them to the existing set of observations which were compiled in such an elegant form in Keppler's Laws (I wonder whether Keppler ever realized what an amazingly good job he did there). That's why I don't see Newtonian Gravitation as an independent theory, only as an (natural) development within Newtonian Mechanics. Lets look at another example, the Electromagnetic Theory. Does Coulomb's Law represent a new theory. No, it is just an empirical finding for yet another form of force. After all, there is no place in Newtonian mechanics that says "Thou shalt have no other forces". In fact the whole issue of what forces there can exist was left by Newton wide open, to be found later. So where does the EM theory start. To my mind, with Maxwell's Equations (though that was the culmination point only, Faraday deserves lots of the credit too). There these quantities, electric and magnetic fields, took a life of their own and became actual physical quantities, having independent existance and propagating through space, not just the "something you plug the charge into to obtain force". Now, I've seen claims that my concept of "theory" doesn't quite agree with the standard concept. Sure, it is but my opinion. There really is no standard definition of "theory" in science and I don't think there is even a need for a standard definition. So, I repeat, what I do is to express my opinions and they should be taken as such. You may recall that I wrote not long ago that "when scientist is talking about science, what he says is not an autoritative statement, just an opinion". I trust nobody thinks that I hold myself exempt from this rule. Mati Meron | "When you argue with a fool, meron@cars.uchicago.edu | chances are he is doing just the same"

For many years the Big Bang theory has been fraught with difficulties. Some of these difficulties have been overcome with ever increasing complexity, giving rise to new problems. It is therefore suprising that the Big Bang theory has survived Ocham s ax. Proponents of the theory are quick to point out Hubble s discovery of the expanding universe, and it is a convincing argument-- so convincing that theorists are willing to invent outlandish schemes to make the Big Bang feasible. Obviously, the only way to be rid of the Big Bang is to interpret the redshift of light in another manner. Unfortunately, there is very little that might explain this redshift. The best answer is the absurd: light is redshifted as a natural effect of space. It would be very difficult to prove this assertion due to the vast distances required to affect light. Unless extremely accurate equipment is invented, I do not see this point as provable. However, it is not a far stretch of the imagination to assume that this effect might affect matter as well. When considering the possibility that matter might be affected by the same effect as light is affected, it would be helpful to consider the high velocities of ions entering the earth s atmosphere. As yet these high velocities have eluded explanation. Once again the best explanation is the absurd: the change in velocity of matter is directly proportional to the distance it traverses through space. Consequently the frequency of matter must increase as it travels through space. It would then follow that: d=k(f-f0) d=km(v-v0)^2 / h a=d / t^2=h / km F=h / k This could be put to the test by electrons moving through a field. I would presume that the field would have to be somewhat strong, but should be within our technology. Questions? Comments? Write me at grundlos@aol.comReturn to Top
Friday, the 22nd of November, 1996 Jeff Inman writes: I guess this conceit is the main reason I'm inclined to take the (seemingly) "anti-science" perspective, in this type of debate. I have no problem with an application of the analytical method now and again, but the optimistic premise that it is the path to the end of suffering, or to peace, etc, etc, seems to me to have been thoroughly disproven by now. Boy, do you have me stereotyped. I would be the very last person on earth to claim that science is the way to eradicate human suffering. What I said (and we could easily retrieve the quote if necessary) is that a light donning of "alternative truth" bears an *ethical* price. Not that it is the source of all suffering, but that it adds unnecessarily to the suffering we already bear. I do think the problem of credulity is much larger than it is given credit for. For instance, I would make the bald assertion that the problem of racism in the United States pales by comparison. The "ain't shit" sounded like you were saying that *I* granted no human worth to those who disagree. Since the heart of Enlightenment liberal political philosophy is to grant equal worth of soul to all human beings, regardless of disagreement, it is this possibly unintended inflection to which I was responding. But, of course, granting "worth of soul" is a far different thing than coming around to buy an airline ticket. Jeff: As the alchemists would say, one has to be able both to analyze and to compose. Hmmm. The translation could be better. I expect you'll get the point though. Maybe that's not a very good pointer, because you'll just rejoin with something about science involving both deduction and induction, which wasn't quite what I meant. Look, induction and deduction were not what I was thinking. But I object loudly to the imputation that science is merely the cold, rational breaking up of all that is beautiful and whole in creation (as though even reason were "cold"!). It seems to me rather profoundly creative. And not just of aeroplanes, but I mean that Rutherford's planetary model of the atom, for instance, is the result of a deeply human and personal relationship with the universe on a par with Leonardo's "Lady with a Stoat". (Again, I point here to Jacob Bronowski's _Science and Human Values_.) Perhaps now would be a good point to repeat my Feynman story, or rather the Feynman story told to me by Marcus, a fellow graduate student when I was at Caltech. Marcus was London cockney and told me that he had grown up trying to get his "Mum" interested in physics. Nothing doing, except once she caught the BBC/PBS special on Feynman and she seemed real enthusiastic about Feynman. So, when Marcus got to Caltech, the first thing he did was knock up Feynman and ask him to write a little note to Marcus' mother to try to get her interested in physics. Feynman sent her a postcard saying, "Dear Mrs. Chown, Don't listen to your son. Physics isn't important, love is. Regards, Dick Feynman" Of course there's more Truth than science can give, even in my philosophy. But my philosophy says first of all that yes, there *is* Truth. It also says science can give some of it. And my experience tells me that even this isn't easy. Mike Morris (msmorris@inetdirect.net)Return to Top

Today was laundry day for me. I enjoy washing my clothes. My shirts are in the majority white shirts and so I scrubb them with a scrubb brush around the collars and cuffs. Most people use an oxidant like bleach but do not like bleach for it eats away the cotton content. The reason I point this out is evident below. It was in one of those Vietnam movies I watched where a soldier said words to the effect. "Why do you think they recruit young men, not because they are in the best shape physically, but because they are so weak in the mind that they do not know what the hell they are getting into until it is too late." Now that is partially true, because a teenager or a soldier in their 20s is apt to fall for these trite and political buffoonery slogans and go off and fight a political war and get killed in it. Whereas older people tend to weigh things, reflect on them and think about them as reasonable or sensible before "running off" to war. > > Subject: Re: Archimedes Plutonium (RE: Vietmath War; France > arms) > From: David MadoreReturn to Top> Date: 1996/11/21 > Message-Id: <32947E29.167EB0E7@clipper.ens.fr> > References: <56oe90$f4u@mark.ucdavis.edu> > <570oun$3kd@dartvax.dartmouth.edu> > Cc: collins@ens.fr > Content-Type: text/plain; charset=us-Ascii > Organization: Ecole Normale Superieure, Paris, France > Mime-Version: 1.0 > Newsgroups: sci.math,sci.physics,sci.logic > X-Mailer: Mozilla 3.0 (X11; I; SunOS 4.1.4 sun4m) > > > Archimedes Plutonium wrote: > > > > > > > Really quite simple. > > > > Peano Axioms > > postulate 1: ..

I did not like the arrogance of your first post. You are young, dumb and arrogant, but you will grow out of it. And some day you will thank me for this post but it will be 20 years from now. I set the above to show you that math is not your cup of tea and that you do not belong in mathematics at all. Probably not even in the sciences but that you are better placed in the arts, something like a French-English teacher, although you cannot even tell the difference between "advice" and "attack". To start a Peano Axiom system the first postulate would be the existence of something. The existence of an entity or entities. Something like this. P1 : There exists a number call it ....0000. and another different number call it ....000001. Once you have two numbers you have a way of creating other numbers from those two numbers. P2 : .....0001 is the successor of ....0000 Here you need to talk about an operation, that of addition. P4 : By SERIES adding ...0001 to ...00001 all other new numbers are created. Now, why in the world would you David, think that this is the first Peano postulate? > > Peano Axioms > > postulate 1: .. DM> I guess that is "0 is not the successor of a natural". To get up a flight of stairs, do you David Madore start with step 67 ? Why not start with step 1 or is that too mathematical for you? The point is that the Peano axioms have a ordering which you do not seem to have yet realized. Now to some readers, this may sound like I am coming down too hard on David Madore. I think not for he starts his first post to me as some childish juvenile intention. David Madore writes: > >Disclaimer: it is up to the reader of this message to discover >for himself where the :-) sign should be inserted. HINT: the set >of such places is non empty. > > Mr Archimedes Plutonium, I have never met you David, your house or ever been to France, but with your two posts to the NET, I have these guesses about you. You have a maid and you are very dirty. In fact your room probably looks like a pig sty with left-over food hanging around. You probably have other people clean up after you and the only time you ever clean anything is when your mother demands you to clean up after yourself. You probably throw paper towels into urinals, being lazy and maid cared for all your life. Me, on the other hand as a comparison has a very tidy room. I never have food laying around. In fact, I do not often eat in my rented room because I hate to have a single crumb on the floor. I am one who believes that cupboards are a rodent and insect grocery store and so any food I have around the house is inside a plastic containers airtight and bug/rodent proof. In my room, I know where everything is. In fact , I am so clean that I cannot tolerate messy people. And I bet all of the famous mathematicians were clean and orderly people. It is almost impossible to be good in physics or math and be a worldly slob. I am a perfectionist and being a perfectionist lends to my being good in physics, and the sciences and math. I am just guessing the above David, that you are a untidy person from your 2 posts. And I would not be surprized that you smoke, gamble and chase women and drive a car with a boombox in it. So I may be wrong, but I think not. I am thinking back to when I was in University and when I was in my 20s. And one thing that is very clear, is that I would not have posted to the Net as a brash and arrogant person like you David with your pathetic 2 posts, because I had no "big or good new idea-- Atom Totality theory". If I had posted at all when I was in my teens or 20s, it would have been only a question or two. I would have posted a question to a Mr. Plutonium, my name would have been Ludwig Hansen in my teens or 20s and a Ludwig Hansen would have posted something like this to a Mr. Plutonium. Mr. Plutonium, If you have the time , please show me how to divide about ten 10-adic strings with each other and having at least 20 digits each. I need the practice. Thanks > > If you mean to say that postulates 1 and 5 are not valid in the > realm of p-adics, you certainly are right. > I say much much more, but you David Madore are too ignorant about mathematics for me to want to continue any discussion with you. One of the things I say is this. Complex = Euclidean Geometry P-adics = Riemannian Geometry Doubly Infinites = Lobachevskian Geometry Which is all way too deep for your little math mind David. In fact, I bet you cannot even do this simple p-adic arithmetic. Divide these two 10-adics and then divide them as 94-adics only the 94 adics where the digits if less than 94 are the numbers-- and if you do not know what I mean here you don't know adics. ....26252423222120191817161514131211109876543210. and ....172.

(g). As a special case, such an expansion holds for p-adic integers. All rational integers are also g-adic and p-adic integers; thus Z is a subset of both I_g and I_p.

I think you say that because you know it is false, but say it to elevate your esteem. You are as lost of a sheep in mathematics as math professors are in math education. Math education in the world is a sorry pathetic sight and a dam waste of time. Math education the world over has become -- around a junior in High School-- has become a notebook factory where pupils learn how to take notes in class and nothing more is learned in class, and then the real learning of math occurs outside of the classroom by studying the book in a quiet place and doing some of the problems and having others from the class help you do the problems. That is why I say eliminate math textbooks and replace them with workbooks. Have a Schaum's outline for all math courses. Classroom is rarely a lecture session. It is almost all a work session of actually doing problems. That Kurt Mahler book is a graduate level book that in my estimation should have never been written. I await the day when the 100,000 lazy math professors, one of them gets the nerve to write a 300 page Schaums outline of p-adics so that High School students can manipulate these strings. > > You don't need to threaten me.

Here is some more advice David as I will not converse with you as I have no time and better things to do with my time. I recommend that you do not seek a career in mathematics or the sciences for you have not what it takes to become successful in those. I recommend you go into the arts something like politics or preacher religion or even French English translator. You are not cut out for math or the sciences judging from your two posts. Of course you will not take my advice and then what will happen is 20 years from now you will say to yourself, By Gosh, I should have heeded the advice of AP. Adios amigo

Mati, again: >"Did somebody ever say that it wasn't a revolution?" Well, somebody >has now. Nicely observed. When I wrote the above post I knew it carried the problem of any other usenet post: not to be boringly long there's always the problem still to be precise, and I knew it'd contain a lot of very 'general' and thus debatable statements. But, I have to say, I hadn't thought of especially this one phrase moggin is rightfully pointing at. Looking at it, I still don't know how to precisely express what I mean with 'evolution of ideas'. If you look at Newtons and Einsteins formulae you find out, that under certain conditions one merges completely into the other. I sure don't want to discuss if this can be called a generalization, but we can easily call it an evolution, just like Non-Euclidean geometry evolved from Euclidean. It for sure is worth a thought if the change in "ideas" behind the formulae (about how the world is etc.) was as dramatic as to call it a revolution. And we'd have to discuss who's understanding is taken as the general base to decide for Rev vs. Ev. For the physicists, the MMX nul result, the disproving of an aether, might have been a revolution, but is this true as well for the contemporarial farmer? Would he have cared for how light propagates? For the farmer, the way how the work of the Wright brothers and Mr. Ford changed the face of the world for sure was much more revolutionary. Is it revolutionary to state, that space is not flat, but curved? Even if it is, the mathematical models evolve from one another. That's what I meant wrt physics. Whereas - coming back to my 'philosophy' example - Marx's "revolutionary" thoughts do have shaken up the world quite a bit, no? So how is it in the history of philosophy? Is there the same sort of ballyhoo (revolution No. 9 ;-) at the surface, while the underlying development of basic structures is rather 'evolutionary'? Is there, viewed back of course, a general 'leitmotif' (sorry, but that's what the Collins gives as translation(sic) for 'roter Faden'), do the new ideas evolve from their predecessors? Do they usually contain them as a special case? Comments? Explanations? Cheerio The most dangerous untruths are truths slightly deformed.

Is it possible to put a command on the newsreader such that no outside follow-ups to a poster will register on the reader until after a set date, say 5 days? I know that a person can manipulate the expiration of posts to the newsreader. How about rogue manipulation of incoming follow-ups? So I suspect one person could also manipulate the time in which outside posts are posted to the newsboard. Even target one person , not all outside posts, just all outside posts to Archimedes Plutonium. Quite obviously, if I post a science article today and someone say in Europe replies to me the next day but I do not see it in the newsgroups of Dartmouth until 10 days have gone by, well , such a situation is hardly conducive to a science discussion considering it would be a lapse of at least 10 days between communications here. I have noticed this lapse in time for several months because I read the search engines and compare them with the Dartmouth newsboard, but today I no longer want to sit still and let it go by. If I see a poster post to one of my articles and the Dartmouth newsboard will not show his post until 5 days have elapsed, that puts a crimp in dialogue. And I should not have to use two separate computers having the Search Engines open and the Net open simultaneously in order to check for follow-ups. The Internet from Dartmouth should have all the articles shown in the Search Engines. I cannot imagine that Deja News has such superior technology. And I am sure this is not the case because back in 1993, when my attackers had not yet learned to attack me, I saw follow-ups to my posts without no delay in newsboard registry. It is likely that there is some glitch in the Dartmouth registering of posts. And it is highly likely that someone can attach a *command* to the system commanding that all incoming follow-ups to a AP post are delayed for 5 or 10 days.Return to Top
Hi, I agree. But we must find out the reason of weight now. Isn´t it ? Any ideas ? Knut KLoeschke@MSN.COMReturn to Top

Very strange -- I have no quarrel with the below whatsoever; especially as regards the futility of "intention" as a category of interpretation. This is, of course, not a postmodern argument, as Raghu seems to assume; the intentional fallacy is quite a bit older...

So what? Why should he? He's not a philosopher. However, he seems to agree with philosophers on a point that was debated amongst us jolly people here. What he did care for : was "does it work", which is the notion some people here find so : odious. Still, you shouldn't take it as gospel, as I've said many : times, opinions of scientists are just opinions, Feynman included. Doxa are doxa, but some are still better founded than others... again, we are not talking in the realm of science; to you, I assume, all of philosophy consists of "just opinions" -- wrong? : As a side notion, regarding the "someone who's in physics comes along : and says the same thing" bit, I trust you can see the slight : difference between "wrong" and "philosophically we are wrong". Certainly; I've never argued for anything but the latter, and neither has moggin even though it seems to give him pleasure to get your goat around this matter.

There is no middle ground, ever... :-) I happen to think overpopulation is them most serious issue affecting future quality of life on the planet... everything else kind of follows from it... Well, maybe the next most serious after nuclear weapons... nuclear what? Yeah, I know, we don't worry about that anymore, but they are still there, in their silos and submarines, and they are still pointed at major population centers, and rogue states are coming closer to building them every year. They are a chronic disease which is merely currently in remission.
