As I see it, there is one big problem with the whole debate. The most likely number of stars in the universe that have life is equal to the product of the number of stars and the probability that any one star had the right conditions to foster the formation of life. We know the number of stars, roughly speaking. If the probability of life forming around any one of these stars is much less than 1/(the number of stars), then the product is small and it is unlikely that there is other life out there. On the other hand, if the probability that any one star has the right conditions to give rise to life is of the order of 1/(the number of stars) or greater, then there is a great likelihood that some other star has life circling it. The problem is that we have *absolutely* no way to rationally assess the probability that any given star has the right conditions to have given rise to life or intelligent life. All we have is the two emotional "arguments", a) "There are *so* many stars, there *must* be other intelligent life out there." and b) "The formation of life is *so* improbable that it *can't* have happened more than once in the universe." Unfortunately, both of these arguments have exactly equal validity and probability until we have some means of assessing how probable (or improbable) the origin of intelligent life at any spot in the universe might have been.

To not make such a postulation in our decision-making would be acting irresponsibly. The analogy need not be extended any further. Becuase we have a basic understanding of the effects of ecosystem destruction, it is also reasonable to take action to prevent these extinctions from happening.

That's one of the reasons SDI never > worked, even in theory. I don't know who told you this Eric, but it's so wrong that it should be obvious where the error is. If there were that much dust in Space, then the images of starlight from the Hubble Space Telescope would be impossible to make out. Of course, clear sharp Hubble images are present on many web sites. Use your search engine. The average mass density in Space is about 1 atom of hydrogen per cubic centimeter. The inner solar system does have a higher density, but that is many orders of magnitude short of being dense enough that it would destructively interfere with a mirror in Space over any normal maintenance cycle. And yes, routine maintenance on all space facilities will be part of the cost of doing business there. See the URL in my sig. for how I think it should get done. As to SDI, there was no ONE thing to work or not to work. there were many highly feasible comcepts. The academic/political resistance in congress to the defense of the Republic was simply too strong between May, 1975 and January, 1995 to get the many workable concepts past demonstrations. Now it's the Clinton cronies who continue the jihad against NMD. That may change soon, hopefully before someone, somewhere in the world, loses a city to ten-second-slum-clearance, courtesy of a ballistic missile. > : : I suppose if you could find some way to send > : : power over long distances (laser?) > Similarly, lasers in space aren't too great. Again, the quantity > of dust out there is unbelievable. Someone has sold you a bill of goods Eric. Yes, there are huge quantities of dust, which is spread over enormously larger volumes of Space. Lasers are EXCELLENT for moving energy in Space over long distances. The size and configuration of the optics have already been calculated by people like Dr. Bob Forward. Do a library search on his non-fiction books about the future, physics, and space industry for more detail on this. > Microwave beaming would be more effective (it's already done in large > quanities here on Earth), but I think the power loss over such a great > distance would be fairly large. When you use longer wavelengths, like microwaves, you simply need to build larger reflectors for them to maintain the same angular beam width. This is where the tradeoff with the lasers comes in. If you want higher efficiency conversion into electricity at the RECEIVING end, then microwaves are probably your best choice, since they can get 80 percent conversion at the receiving rectenna. If you want smaller optics, then lasers are your best bet. > Also, given the inefficiency that still > exists in converting solar energy to anything useful, a solar generating > station, even one near the sun, that converted solar power to microwave > energy would be hard-pressed to do anything useful. There are many solar power station concepts that could use 20-40 percent efficient dynamic generating systems for electricity. Essentially these are space-going versions of the Brayton Cycle powerplants that are run by coal, oil, gas and nuclear at the surface of Earth. You just heat the boilers with solar light concentrated by mirrors, which will be maintained by telerobots, if I have my way. Photovoltaics are either sensitive to radiation damage, of low eficiency (2-10 percent), or narrow bandwidth. Pick one problem to live with and you can get rid of the other two. The narrow bandwidth of course doesn't pose a problem for converting laser light of the right wavelength. That's the sort of PV that would probably be used at the receiving end, if laser wavelengths are used. > Finally, given the > magnetic field fluctutations that exist close to the sun, you'd have > problems with everything from circuitry to actually sending the microwave > beam in a straight line. Sorry Eric. The calculatable intensity of a magnetic field needed to effect either a microwave beam or a laser beam is far stronger than anything we expect near the closest orbits that even near-solar power stations would be placed. (about at the orbit of Mercury) The first stations would best be placed in geostationary or geosynchronous earth-orbit, so that they could power both Earth's continuing industrial revolution and the extension of that evolution into Space. > "Those who depreciate agitation yet desire change are those who want crops > without plowing up the ground.

Quick summary of what follows: 1) Data which supports the Green House Effect supports it. 2) Data which ignores the Green House Effect supports it 3) Data which contradicts the Green House Effect supports it - needs more study. 4) Anyone who disagrees is obviously unfit to judge.

Good point.

The Nobel Prize in Chemistry was awarded for work on the relation between CFCs and ozone depletion. This has essentially nothing to do with the question of global warming. (CFCs are in fact greenhouse gases, but that was not particularly relevant to the awarding of the prize.) > -- the green house effect is mainstream science now, not just some > environmental extremism.

There may be some elements of truth in your assertion, but I don't think it is anything close to being that simple. There are some differences between the Northern and Southern hemispheres and they may be related to sulfate aerosols, but I don't think anyone claims such a simple direct relation. > > Third, weather patterns in the U.S. are driven to a large extent by the > position of the Jet stream.

I am an active information-seeker, and examine anything, time permitting. I honestly have not seen or heard of "Extinction Rates", and I've spent quite a few hours in library halls doing research. At some point (a point far since passed), it simply becomes a lost cause to deny the global extinction crisis, in the face of overwhelming evidence, if you were inclined to do so.

If you only study to gain data and knowledge to perform a particular task (e.g. work as a marine biologist or an engineer) then you can ignore anything that doesn't relate to that task. If you enjoy learning as part of a whole life experience then the ability to ignore facts which don't suit your prejudices is very difficult. As a keen participant in environmental issues, I am regularly reminded of the inability of intelligent people to see the broader picture within which details fit. e.g. the failure at Chernobyl, and the nuclear power industry's reaction to it, has been used as a learning experience to make an excellent source of energy even safer.

The posting and response below bothered me a great deal. I suppose that it is just a sign of the times that the term "evolution" can be co-opted and turned into an excuse for human distruction of nature. I would like to clear up some misconceptions that came out in the 2 messages: --First, survival of the fittest (a phrase, by the way, that evolutionists shun) does not mean survival of the strongest, or the biggest. It implies that any organism that is well suited to a certain environment, will persist there. (The definition of the 'fittest' then becomes 'the organism which will survive in a particular environment,' so the phrase 'survival of the fittest' is actually redundant.) --Second, on the question of whether grizzly bears 'like' the environment in California, I'm certain that grizzly bears are quite suited to this environment. Yes, it is true that environments change, and organisms evolve to suit their new environment, but how fast do you expect any animal to do this? In the last century, humans have probably made more changes to the environment than used to occur in thousands of years. Tiny changes in any given species take hundreds of generations to occur, so it is unlikely that bears could suddenly develop some feature that would save them from farmers' guns. I could go on, but perhaps I should work up to the rest of the biology course slowly. ------------------------------------------------------------------------------ Fiona Currie : "We are not talking about gorse-bushes," said Owl a m233701@er.uqam.ca :little crossly. : "I am," said Pooh. --A.

COHEN america2@ix.netcom.com
The probability of life elsewhere other than planet earth is exactly 1.0! This is a true statement and I have evidence! So does NASA in so far as they keep blasting it into space. Suffice it to say that there is life in space at this very moment. Moreover, what goes up must come down! It's all relative, but there still ain't no absolutes. If in theory one wanted to assert that 'life must exist on another planet' one would also have to assert that life did not exist on another planet if one was to make these assertions within frames of empiricism/science. To assert that 'alien life' existed one would need empirical evidence to back the assertion and no one has any. Theoretically, if one says that 'alien life' does indeed exist, but they have no empirical proof to back the assertion, it is not theory but more aptly dogmatic posturing. -- ----------------------------------------- Carleton University ---------- Robert G.

Although this also brings up arguments about space spin-off's, I think everyone understands Transistors, IC's, satcomm, and other space technologies as being useful.

Is this correct? Don't know if they ate radium, but they certainly lived and worked in a heavily radium and polonium contaminated environment for a while. Bequerel, for some reason, was not instantly struck by divine inspiration as to the horrors of ionising radiation when he discovered radioactivity - or if he was, he didn't tell anyone. Pierre Curie died young, he was run over by a bus. Marie Curie died at age of 67 From URL http://www.mbnet.mb.ca/~rstriem/papers/lisa/curie2.html a research paper by one Lisa Ford, we find: "Curie died; she was 67. Her post-mortem report by Dr. Tobe stated that the disease was an aplastic pernicious anemia of rapid, feverish development. The bone marrow did not rea ct, probably because it had been injured by a long accumulation of radiations (Eve Curie, 1937)" The reference is to Eve Curies 1963 biography of Marie Curie.

So by the time anything rotted away the material that would be left would not be radio-active. This is one of those issues that is not understood or admitted to by "anti-nukes". I am neither by the way. I simply dislike misinformation which is what you presented here. If you are really concerned about radio-active emmisions into the air then do a little research on the radio emmsisons by a coal fired power station. You will find that a 500 megawatt coal fired station releases more radio-active uranium into the atmosphere in one year than a 1 gigawatt Nuclear Station is allowed to release in its entire 40 year lifetime. ---Bill -- =============================================================================== ___Bill william@fractl.tam.cornell.edu wth1@Cornell.edu ===============================================================================Return to Top

Also, if anyone has trouble obtaining the raw data (I have >included pointers to it) or problems viewing this web page (it is my >first attempt at developing one!), please let me know. Hmmm. Big changes in output for relatively small change in input aren't really that unexpected. The weather system is chaotic, so small changes can quite happily get amplified into big ones. Couple of things to bare in mind - temperature is a measure of average energy and you're looking at average values over a long length of time. What you're seeing is a correlation between the average ammount of energy in the weather system and the level of CO2 present in the system. You're big assumption here is that the CO2 is the primary cause of the increases of energy in the system. If this is correct, then your predictions are reasonable. An alternative is the the CO2 levels track to the level of energy in the system (ie as it gets warmer more plants live and produce more CO2, when it gets colder the plants die and there's less CO2). Oh, and don't forget the the snow and ice release CO2 as they melt (the same CO2 the Vostok boys were measuring). The other thing to check is the accuracy of your temperature measurements. If they are just measurements of temperature, then they aren't telling the whole story. The weather is a chaotic system and you have to consider all forms of energy that are in it. Energy manifests as temperature, wind speeds, evaporated water and melted ice amongst other things... If you're only tracking the temperature part of the data then your figures for total energy vs CO2 are to low. The first noticably effects of global warming should be a tendancy towards more extreeme and more prolonged types of weather. Some parts will be warmer, some windier, some weatter and some colder. What we're dealing with here is a full blown, real time, chaotic equilibrium, not a slow, linear system. When you kick energy into the linear system it gradually gets warmer. When you kick energy into a chaotic system is starts doing different things as it gets pushed further and further away from it's attractors. Mik

They’re one and the same Robert. The same "Harold" whose promotion of subservience to the vile and violent will “herald” the use of those weapons and mindsets he presently wishes that all would, as acquiescent sheep, accept and ignore. ie. Harold Brashears Go for greed’s gold, grab the silver from a dangling Juda’s, Harold? Forget so quickly that other people understand the old hymn, “There’s no whore like a political whore!”? Sell out to insanity? Can a few more pennies for your pension really mean that much? Think about that Harold and while your at it, explain why, at your station in life, you would sell out your humanity. The bastards who’ll pat you on the head aren’t worth it Harold. Think about it. Join the refusal and wake millions of sleeping fellow Americans!! Go for it Harold!! Be America's standard bearer !! Go for it!! America needs someone with courage and character to risk the slurs and the sneers and do what your forebears knew was needed!! Speak up!! But, if that’s beyond you Harold, if nature did not grace you with sufficient will and insight to see through and address the insanity we face, I ask that you simply reconsider your current support of the insanity, with a view to saying “Enough!”. Thank you. And thanks for asking Robert. :) In closing: Many have contacted me regarding how to proceed with preparations leading to a fullsome involvement in the refusal. Many have asked that I become personally involved in or otherwise assist their efforts. I wish I could. The sheer numbers however, now seeking my personal involvement, were I to attempt to help them all, would result in burn out and subsequent inability to maintain my goal of waking the balance of a now questioning world. The effort, and the refusal, would slowly grind to a halt. Now the good news! All necessary info is free! Everything you need to know can be accessed by querying "taxfree@planeteer.com". And the only questions that matter are these: Can we do it? Can we waken humanity? To a safer, saner world. To the development of reason, a new vision of duty and the worldwide use of T2020-88.

Something tells me that argument "ain't gonna make it" when you turn in the first draft of your dissertation. As for "serious scientific debate", it's noteworthy that you responded to the last phrase of my first sentence and completely ignored the structural content of my response. Dick

The proceedings of the 4th International Conference on Semi-Solid Processing of Alloys and Composites are available for sale. The conference was held on June 19th-21st 1996, and was attended by over 200 delegates, 70% of them from industry, and from all five continents. The proceedings consist of 67 papers (hardback, 362 pages, A4 size), all refereed, and all professionally typset to give a uniform appearance. At least 70% of the papers emanate from commercial sources, reflecting the increasing importance of semi-solid metal forming in manufacturing industry. The reason for this accelerating rate of development is the ability of semi-solid metal processing to lead to improved product quality, die life, energy consumption, production ergonomics and safety. The proceedings contain contributions on modelling, microstructures, rheological measurements and equipment, as well as on practical examples where the semi-solid casting route has been applied commercially. Most articles discuss semi-solid casting of aluminium alloys, but there is also material on ferrous and copper-based alloys.

Columbus differed with the more knowledgeable geographers and navigational scientists of his time about the size of Asia and/or the circumference of the Earth. He was wrong, and they were right, but he was lucky that there was a previously unknown (except to the Vikings) continent between Europe and Asia to the east. One can conjecture about what would have happened had he failed. It is fairly clear that eventually Europeans would have found the `New World', which I remind you had already been found many thousands of years earlier by other members of our species. (There were even at least three highly developed civilizations on the North and South American continents.) Probably the most significant barrier to such voyages of discovery was the inability to determine longitude. This was solved by a combination of astronomical techniques and the development of highly accurate clocks. It seems likely that by the eighteenth century Eruopeans would have made the same discovery if not earlier. But the Inca, Mayan, and other societies might have developed further in the interim, and it is not clear what the result would have been. I suspect that many Europeans would have migrated to the Americas but it might have been under very different circumstances. The institution of African slavery might not have become established in the Western hemisphere. Someone could easily write an alternate history of such a world, and perhaps it has been done. Since many of us wouldn't be alive in the alternate world, the majority of us might not approve, but it is not clear it wouldn't be just as good (or bad) a world as the one we have. > Some people look forward, most people look at their shoes. > > == John == -- Leonard Evens len@math.nwu.edu 491-5537 Department of Mathematics, Norwthwestern University Evanston Illinois

Right now you are simply proceding by argument by assertion of personal belief. Why in the world should anyone pay any attention to your personal beliefs? What qualifications do you have? Have you published any of your contentions in peer reviewed scientific journals? Please refer to the IPCC Reports which discusses the issue of urban heat island effects. This issue has been thoroughly explored and it does not suffice to explain what appears to be observed warming. The issue of whether or not we have observed warming due to enhanced greenhouse radiative forcing is quite complex. There are in fact reasonable arguments which critics have raised. But I don't think you have the foggiest idea what they are. If you are going to engage in polemics on this issue, you should at least arm yourself with sensible arguments instead of engaging in simple minded arguments not particularly supported by the data.

It seems to me : the goal of such can only be to increase the size and power of government : since no net environmental improvement results and there are many times : negative impacts. On the other hand maybe I just can't take a joke. I wonder why libertarian musings always seem to involve attacks on someone's scientific integrity. Shooting the messenger? In any case, if you're looking for political conspiracy theories, blame the incinerator folks. They did an active lobbying effort, involving such innovations as contacting lots of environmental groups to try to make common cause (talk about dining with a long spoon!). I don't think that this lobbying would have had any effect if BIFs hadn't been already ripe for regulation. -- sci.environment FAQs & critiques - http://www.mnsinc.com/richp/sci_env.htmlReturn to Top

We've seen the tree line in the Alps retreat further uphill, for example. The cold winter in Europe and the US is blamed, in part, on warmer Pacific Ocean temperatures.
