Well, Lets see. Why dont you take a puddle of GUE and put it in a sterile container. Now Apply ENERGY via the Sun or Electricity (or both) and sit around for about 30 years. Now check the mix, and see if it is the same, or see if it is more complex than before. Now sit around for another 2 billion (give or take a couple a billion) years and see if life crops up. Now I have a question for you, if there was life in the Jar of GUE after that length of time, would you be GOD? : karl, : That is the same question I have been trying to get an answer to!

Some Thing that we cant see, and doesn't interact with us, He made it just appear about 5 thousand years ago, all in a 'devilish' ploy to trick us into thinking it was many billions of years before that. Sounds like an X-files episode..... I will agree that 'God' created the Universe, but not your 'God'. And not your way.

Logically, if I wasn't coherent then you wouldn't be talking with me. So, let's get over mutually insulting eachother because that certainly isn't going to lead to the place I want go --- Progress. And being as proficient as you are with language, you should've realized that I specifically wrote "I never claimed to be coherent". A reasonable Being wouldn't have to go around _claiming_. But it's nice you clung to that otherwise forgetable trivia of Reality. You are certainly too quick in trying to intimidate your debators with unfounded personal attacks. Do you really think that's helping your case --- assuming you have a point to offer? If I had to edit your guess I'd say "Sci.physics: love it!" and I'll try address why. Since man's recorded history, men have noticed patterns in physical phenomena. You know why Galileo dropped those balls so many times? Well, besides not having the Internet to distract him, I'll bet he was hoping against hope to just see *once* if the ball wouldn't do the same thing. I can hear him praying in Italian before dropping the balls "Please O please do something different!". Finally Galileo realized that praying wasn't changing the outcome of what the balls were motivated to do. So he made the best of it rather than deny the experimental observational fact. We praise Galileo accordingly. As such, by extrapolation, other men have realized that it's better to love physics than to leave it. For men can't actually "leave" physics. There is no physics-free-place to go. And don't feel imprisoned --- for that would be to miss the fascination entirely.

Name calling can only be entertainment for so long. It gets nowhere though. From my personal experience, most scientists are concerned with having a decent paying job within Science than worrying about reflecting on it. Though this may seem funny to you, it's far far from funny when you have no money. Philosophers and theologians may be better equipped, IYO, about thinking about science. Where scientists get bothered is when science is misrepresented, otherwise devalued, or told by outsiders that science decisions are trivial (Case in point --- Silke's comment regarding the estimation of airplane fuel requirements). What's utterly ironic inspite of all this, everybody from lawyers to palmists will unquestionably and unerringly claim that their works are somehow "scientifically sound". It's enough to make you laugh --- forever. I mean I love to point out hypocrits as much as the next guy, but groups like the Christian Scientists, et. al. take the cake. Though it's unbelivably funny, all these people take themselves way too seriously and want to get --- as it were --- equal billing in respect, politics, and classrooms. However, unquestionably, there are pure philosophers and theologians who are not motivated by self-serving misguided (political) reasons. But I doubt that they are the outspoken vocal ones.

Physician, ask thyself. I well understand the pitfalls of Self-Deception. Trust me, that's why I leave the door open. That's why I read these threads. Real time people with real time thoughts. I learned from everybody though I've come to hate a few for their style and idiocy. But for the most part, I'm glad I chose science. I might have exceled at deconstructionism and _that_ scares me! I really did in truth enjoy reading Zelany. Fact is, you're arguments brought his and a few other's to my attention. So not all bad goes unrewarded. But I'm a certified optimist. It'll get me one day. ;-) Let me be the next to inform you, there *IS* an objective "Reality" and we humans are an intricate part of it. If one's philosphy doesn't allow for the determination or merely the acceptence of such physical reality, then the philospher really isn't doing a very good job. There are very simple facts of human's observations that confirm the existence of an objective reality. Whether it exists for any "purpose" or not is a secondary issue --- from the scientist's perspective. From *THIS* scientist's perspective. Why is the issue secondary? Easy, because the first issue is to manage to survive in this proovably hostile environment! Having succeeded at surviving, then the philosophers and theologians and palmists can all live under the shelters science helps make and LITERALLY bash on science to their heart's content. If that is what they desire. Scientists will defend themselves. But why battle? I like Sokal. Seems like a well-meaningful individual from what I have read of him. If that too is a *hoax*, then infinite kudos to him. :-) The point about true Science is that since it is independent of social prejudice, it is immune from both criticism and praise. However, scientists are humans and humans depend on Society for mutual coexistence. You can bash the scientists --- and they will not like it of course --- but the Science remains the same. Kepler is the classic case in point. He lead a miserable life personally. Financially broke. Death and desease. Witch hunts and what not. Despite all this madness in the society around him, he found stability in the patterns of the "wanderers" around his Earth. Though we praise him now, it doesn't change one iota the misery that was his personal life. We modern scientists don't want to live miserable lives and social movements that are antiscience will get us to stand up and REASON. [trim] >>Without all these fancy evasions and more... Tell me this >>If "Newton is wrong" then how would moggin make the Universe "right"? > > Righting the universe is beyond my ability. If you resolve to believe this, then so shall you achieve. Why set yourself up for the failure? Perhaps you're being rational and just comprimising with the Nature/God-Given limitations of your ability? Anyway, it does not matter as far as either Nature or God is concerned. See, scientists can be inspirational. The point you and Society at large are raising is that scientists have failed at communicating about their work --- which influences every life directly or indirectly. That's what I gather and it's only valid in the domain of one man's opinion. What you are saying is that Science needs to be addressed from religious and/or mystical, even literary, perspectives. I sincerely doubt you've encountered any scientist that would restict your privilege to do so. It's only when you persist bitching (for lack of a better word in our Era) that "Newton is wrong" and by extrapolation all Science must be wrong because there exists no such thing as numerical (Platonic) perfection that Physicists feel the need to defend Science's ideas. And when Science&Scientists; are saying that the Laws of Science are ultimatley independent of the beliefs of the discovers, you all need to accept this by "understanding" it. It ain't hard Barbi! Trust me. Please don't turn this comment into something sexual. I know what rigid is. ;-) moggin, your particular point appears to be that a specific religious mystical mindset inspired Newton to succeed despite being Universally wrong in the light of later observations. Problem with this is that it is not true that a specific religious mindset guided him --- no matter how religious he personally may have been. Darwin too was a religious being but the evidence was more overwhelming than scribblings of ancient texts! And since the final product these individuals discovered is independent of the personal Beings these men were, it's reasonably true that their mystical beliefs are irrelevant to Science. In sum, Reality shapes our perceptions. All our perceptions combined couldn't make the Sun geometrically square No matter how hard we prayed Or how throughly we brainwashed ourselves. Somethings just ARE. The Laws of Physics are a result of seeking out these objectivities. And the search continues because we don't have any final answers==truths. How do I convey that scientists would not discover anything if there was nothing to find? Preexistence is a prerequisite. If I have now entered metaphysical territory, don't worry for me, I ain't lost. Mahipal |meforce> http://www.geocities.com/Athens/3178/

The role of Lorentz invariance in the completed theory would then be very problematic. An 'aether' would be the cheapest solution. But the unobservability of this aether would be disturbing. An aether would represent an absolute frame of reference. ---- When I hear "absolute motion" I can't help but think of Sir Issac Newton's experiment with a spinning bucket of water. You can tell that a bucket of water is spinning because its top is concave. What is the bucket spinning relative to? Mach's principle is that it is spinning relative to the "fixed stars" (well, at least relative to the the average density distribution of matter in the universe). For the feedback from the average density distribution of matter in the universe to work, the Wheeler-Feynman absorber theory is as good a starting point as any. --Best regards, --MikeReturn to Top

The rheostat provides a varying signal to drive the fuel guage. Some fuel guages are of the magnetic-coil type and others use a bimetallic strip that is heated to move the pointer. The bimetallic types tend to average the sloshing of the gasoline so that the pointer doesn't bob up and down too much. Some aircraft use a pair of metal strips positioned vertically in the tank. The capacitance between the strips varies with the fuel level. Very nice, no moving parts, but pretty expensive. George Lyle

Will you then consider 'that there is no absolute anything" as the ABSOLUTE TRUTH. It is then to that ABSOLUTE TRUTH that everything else is RELATIVE. You cannot escape the ABSOLUTE, no matter how best you try!Return to Top

There is, however, no aether or spacetime drag so we can't detect the aether by optical velocity measurements. We do not need to do so because spacetime is illuminated by light, and light is the absolute reference frame. Regards, Edward MeisnerReturn to Top
Ok, instead of doing something really useful, I've been thinking about this physics problem. The stimulation was the assertion that the absence of gravitational field inside a spherical shell was "intuitive", if you found the divergence theorem intuitive. Fine. I grasp the arguement; but it still seems like a peculiar special case. What happens if we break the symmetry? Suppose we dimple in the surface of a spherical shell at one point. Now go for a pleasant float in the interior. The field from all other points is as before, but this dimple is now closer to you... so you will be attracted to it from all points in the interior. Correct? Now what if we break the symmetry in a different way. Say we squeeze a hollow sphere between two poles, but maintain reflective symmetry. Does this create a field in the interior? Which way would it point? Does the answer depend on the exact shape of the distortion? How about a general ellipsoid? My intuition gives me no hint. Does yours? this induceReturn to Top

I would disagree, as much as I like the word *conflating,* which I suspect will be this year's intellectual word of the year. I've always thought (since taking a couple of courses in the philosophy of science as an undergrad, lo those many decades ago) that proper Science involves a method, or an approach, or a state of mind, or whatever you might wish to call it, that formalizes skepticism and insists on empirical evidence before certain theoretical propositions will be considered as demonstrated (or even as likely.) If one simply says that noticing the deflection of a compass needle near an electric current represents science, then one could also say that noticing that a seed produces a plant is also science and the person who noticed it a scientist, even though that person might reject any concept of formalized skepticism and attribute the production of the plant to one of his household gods. I'm suggesting that there are many *science-like* activities (that may even use the techniques, language and instruments of science) which are not really Science -- engineering is one, processural archaeology is another, quantitative history another. (I would agree that noticing a needle deflection and then doing a careful series of studies to find out the degree of deflection, the laws of deflection, etc., are Science; using the deflection to set off a burglar alarm, or detect a wall stud, is not.) What I was suggesting in my first post is that a lot of social and technical advancements claimed by "scientists" were actually the result of "science-like" activity, and were discovered by people without knowledge or use of Science as a means of investigation. The fact that North American Indians used red-willow bark for centuries as an analgesic, not knowing specifically that it contained salicylic acid, was a product of intelligent observation and insight, not science; the production of the same salicylic acid by Bayer, as aspirin, seems to me more akin to engineering than science, since the desirable result had already been observed and what was needed was technique, rather than any new insight. Where is the Science in this? JCReturn to Top

Neo-malthusian alarmists like Paul Ehrlich and his "Population Bomb" of the 70s have been their predictions turn out to be false time and time again. As the third world develops economically, their population will level off to be more like industrialized nations. The biggest oppostion to these forces the worldwide Catholic prohibition on birth control. The Pope just said evolution does not conflict with Catholic faith, we can only hope that a lift on the birth control prohibition will come some time down the road. -- Jeffrey Borrowdale
