  1. would you be able to tell me what is the averege amount of steam per second needed to turn a turbine in an electric powerstation?

    No. That would require me to read your mind to find the efficiency and size of the powerstation you are asking about. It would also require me to assume some unit of measure to answer your question with when there is no particular unit of measure for a quantity of steam. This might produce something you could find useful though...http://www.google.com/search?q=steam+turbine+calculations

  2. My concern is that observation often falls short. Is theory really enough? Many times even 'evidence' is merely subject to limited interpretation. Isn't a belief in evolution merely based on presupposition, much like many religious beliefs? In other words, if one did not begin with the presuppositional belief, then one would not have interpreted the 'evidence' to mean this or that. What's really the difference between entertaining an 'evolution theory' and a 'god theory', if any?

    You seem to be asking for proof that evolution is more than it is. Evolution is simply a theory about the various change and adaptation of species over time. It is not necessarily a theory about the origin of life. Aside from questions like, "how did life begin?", we know that adaptive and mutative changes happen in species without doubt; it is a fact. A new flu vaccine is needed every year as a result such change; the flu evolves, no doubt about it.

     

    On questions like "how did life begin?", "where did we come from?", "why are we here?", the answer is "we don't know". The theory of evolution does not claim to provide proof of any answers for such questions like some postulate. These are the questions that much of the alleged "evolution vs creation" debate boils down to. Scientists say, "we don't know", creationists say "god did it". Objectively now, which group can claim they are undoubtedly correct, the "we don't know"s or the "god did it"s?

  3. we go to the same school, we're in the same computer class...we're gonna have the same ip address (FYI). and if you'll read my post, i explained what happened.

    I realize you explained it but it still seems like you are Eric to me....Oh, BTW, if that other site is ignoring you I wonder why you are not listed as banned there anymore. Did you ask them to get back in with another chance as well?

  4. my point in debating it here is b/c i don't know who or what moderator banned my FRIEND not ME. i won't be on here much longer. i'm only here to figure out what's going on and if there is any way ot solve the problem. since i do not know who banned him' date=' i will post it "publicly" for all to see including the one who banned him, in hope that the one who banned him will come out of hiding and confront the problem.

     

    Edit:

     

    Danny, i'm quite sure he realizes that now. teh theory is written in a very specific way you cna only fully understand it from reading it from front to back. he said he wrote it this way so that others can catch the train of though and see it the same way he did, making it easier to understand...wait, yea, he just told me he made a mistake from putitng that one up there. he was wrong and needs to fix it, hasn't gotten around to it yet.

    How telling...now you're signing your posts as cd. Me thinks fiend=cd27. I wonder what a comparison of ip addresses and/or email addresses might reveal.

  5. Theres an urban myth attached to super heating. Its said that if you heat up water in a ceramic cup for too long in a microwave it super heats and if you take it out to quick the water "explodes" and you could get 100+ degree centrigrade water all over your hands arms etc.

    Actually, when you think of boiling water, you think of bubbles coming to the top. Where do the bubbles come from? They form at a nucleation site. Usually this consists of a small flaw in the container or a seam--say, where the sides meet the bottom--but it could also be turbulence in the water due to convection. Such a flaw or turbulence is common in teapots or saucepans used to boil water on the stove. However, when you are boiling water in a microwave, you are probably using a ceramic mug, which is much smoother and may not have a good starting point for nucleation. On top of that, a microwave oven heats more or less uniformly, so the amount of convection and turbulence in the water is greatly reduced. Without nucleation, the water just gets hotter and eventually becomes superheated; that is, it exceeds the normal boiling point for water without actually boiling.

     

    This is when things can get touchy. If you move the cup around a bit, or drop a teabag into it, or put your spoon in to stir it, or whatever, you can provide the nucleation site the water has been looking for. So it turns from a superheated liquid to a boiling one--quickly. Usually, this will just mean it boils over the top of the cup, in which case you'll only be burned if you happen to be holding it (such as if you took it out of the microwave and jostled it enough to start it going). It could also splatter a bit, just as a pot of boiling water occasionally throws up some scalding drops. But it's not going to "blow up" and throw all the water into your face.

  6. It looks like maybe the server config could be contributing, i.e.

     

    Apache/1.3.33 (Unix) mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 PHP/4.3.11 FrontPage/5.0.2.2635 mod_ssl/2.8.22 OpenSSL/0.9.7e

     

    mod_bwlimited doesn't allow bandwidth bursts so intermittent high volume will get a server busy.

  7. In my case I actually favored my left hand as a toddler but my mother forced me to use my right hand for everything. This was a common practice at the time because of the limited availability of left handed products for consumers, i.e. scissors, baseball mitts, guns, etc.. As I got older I learned that it was not very difficult to learn to do things with my left hand, a little practice and I had it. I assume this shallow learning curve is the result of me having been born favoring the left hand to begin with.

  8. i still don't understand why mercury is liquid at room temperature.

     

    Francium and caesium (cesium) are liquid. I think this is due to large atomic size and single valence electron. Bromine is liquid due to weak Van der waals forces.

     

    Galium is liquid at room temperature. What are the reasons?

     

    Any help?

    The freezing point of mercury is -38.87°C. The melting point of gallium is 29.7646°C. What's to understand?
