  1. Is the brine you are talking about using for drilling something like the "mud" used in oil drilling? Something like this? http://en.wikipedia.org/wiki/Drilling_fluid
  2. What sports or utilities are these SUVs being used for? It seems like a really good example of how the US looks to the rest of the world as if they have lost the plot. Who goes out and thinks " If I spend more money, I can get a more hazardous vehicle that costs a lot more to run. Yep! that's the right choice for me!"? Incidentally, if you can't see past the SUVs then you shouldn't be going much faster than walking pace.
  3. If you gave Newton a radio he would have to wait a while before there was anything much to receive. He would also have trouble buying new batteries for it. However I think this discussion is a bit muddled up. They found gravity because they had noticed things fell. They found magnetism because they noticed the properties of lodestone. They found electricity because they noticed the effects of static electricity and the effects of "galvanic" electricity and eventually realised they were two aspects of the same thing. They found the strong nuclear force because they noticed that, in general, nuclei don't fall apart. They found the weak nuclear force because they noticed that the strong force didn't account for all the observations of radioactive decay, notably beta decay. In each case the force was recognised because it had an observable effect. If there were some force that we might call the telepathic force then we would recognise it if it had an observable effect. However, since no telepathy has actually been observed, there is no reason to propose such a force. A quick swipe of Occam's razor and there's no substance to this thread.
  4. UV light penetrates pure water very well, but not sea water because it has lots of things in it- not least plankton, bacteria etc.
  5. Almost anything you add to copper will reduce the conductivity slightly- probably not enough to matter for signal lines. However, copper is relatively easy to refine. The thieves would just have to sell it to someone further back in the processing line. In the limit, they could sell it as copper ore. Sending it through the process that turns raw copper ore into pure copper would certainly remove any additives. You would cut the profit margins for the thieves and perhaps they would quit stealing copper. That leads you to two other questions. What would they do instead? also, how could you protect old copper. There's lots of it already in place.
  6. "We know that Al tends to form amorphous oxide layer when exposed to atmosphere at room temperature." No we don't. I'm fairly sure I have read that the layer has a definite structure- albeit different to corundum. If my memory serves me well it's a defect rock salt structure.
  7. I rather suspect that this thread is written by Victor Rajic. If I'm right then this thread shouldn't last any longer than the last one. http://www.scienceforums.net/topic/56009-telepathy-schizophrenia-god-mystery-of-my-life/page__p__597780__hl__%2Brajic+%2B__fromsearch__1#entry597780
  8. Are minors who have sex with adults 'victims'? Yes.
  9. I looked at this "That's a fine premise for a really good question, but I wonder what data (if any) supports the premise. Perhaps... if no one has compiled data to support or reject the assumption... we could do it ourselves. Norway (and specifically, its GDP) I see was given in that regard, but looking at the top few countries listed by GDP per capita, I see that a good deal of the top listings (4 of the top 6 for example) do legislate the death penalty which stands out as the most severe punishment." And I wondered why someone chose GDP as a measure of "development". Personally, I don't see any country with a death penalty as civilised. (I might accept that, in wartime , that would be different for some crimes). In any event, Qatar has a very high GDP and an attitude to human rights that, at the most positive, could be described as "better than some of its neighbours". The UAE isn't most people's idea of a well developed country either. http://gulfnews.com/news/gulf/uae/crime/women-get-jail-and-deportation-for-kissing-on-dubai-public-beach-1.106824 Money really isn't everything.
  10. It all rather depends on the definition of temperature. The temperature of the active material in a laser is, from at least one point of view, negative. As it cools down it goes through an infinite temperature.
  11. "heavy water is water with deuterium oxide in it" Not really, it is deuterium oxide. "Deuterium unfortunatelyis heavy hydrogen and can be quite dangerous to manufacture." Nor particularly. "In order to gainhigh-purity deuterium, electrolysis of heavy water with the D2O concentrationof more than 99% is usually used. " Not much help, sine the OP is trying to get heavy water, not use it up. So basically to getheavy water, you need to get a dustbin full of water, electrolysis the shizmout of it, and then on the... cathode you should get your deuterium. Once youhave this, you can add it to water to make purer heavy water." nope. " And heavy water isonly used in so far as to MAKE deuterium, which thanks to the paper below hasthe following applications:" No, D2O is used for plenty of things without conversion to D2. So, as I said, Unless and until Klein gets back here and explains what his first post meant there's not a lot of point in continuing this thread.
  12. For a start, I would do it without the aid of a fairy tale.
  13. If that law required a gas cylinder of SO2 to be labelled "Sulfur Dioxide" rather than with the English spelling would it show that they didn't know what they were talking about? Will they rename the dept of labour to enforce the rules?
  14. Unless and until Klein gets back here and explains what his first post meant there's not a lot of point in continuing this thread.
  15. That works so much better if you remember to put capital letters on English and Scots as well as at the start of the second sentence. Incidentally, I think I know what he meant to say. I'm just trying to work out what was meant by what he actually did say.
  16. Can anyone parse this "NATURAL SELECTION the last said so SOPHISTICATE MISSILE in the hand of scientists launched against REALITY . " in a way that actually makes grammatical sense?
  17. Since magnesium hydroxide is practically insoluble measuring the change in density would be quite difficult.
  18. "I have been told that you can pump water over the surface of magnesium and create heavy water." You were misinformed.
  19. T2 needs to be a load cell too. (or at least, that's a more conventional set up because it's a whole lot easier to work with.)
  20. Coal and charcoal are complex mixtures which contain carbon as well as a whole lot of other compounds. (Incidentally, you missed out the nitrogen, sulphur and other things.) "Charcoal and coal are hydrocarbons (with much C and little H) which allows them to burn, as opposed to graphite." That's the sort of thinking that gave us this http://en.wikipedia.org/wiki/Windscale_fire Graphite burns well enough- it's just a bit hard to light. Also, if you roast coal you get coke which is much closer to pure carbon (almost all the O, N, H, and S are removed) but which is still used as fuel. "Coal is extracted in mines and normally pyrolysed before use" Not really, most of it is burned. Some is turned to coke, but since the other products i.e. the gas and tar are valuable this process is just as much "using" the coal as setting fire to it. "Carbon is the element and is also a synonym for graphite" and also for diamond and C60 The properties of high purity well ordered graphite are reasonably well known. The properties of mixtures like charcoal are, of course, different and more variable.
  21. I prefer the old version. "A friend will help you move house. A real friend will help you move a body."
  22. "Oh Flying Spaghetti Monster, I pray you'll help John Cuthber learn how to use quote tags someday." Quote tags are an invention of the Devil- so I only use them sometimes.
  23. My best guess is that the coal rods are for fuel rather than anything else. Perhaps as a way of using coal dust which is otherwise a messy nuisance. According to this http://info.ngwa.org/gwol/pdf/722500216.PDF (P39) The resistivity of coal varies a lot.
  24. "Should they seek psychiatrict help or go to a churh where they will hear words like "Love" "Truth" "Honesty." " I can hear the same words from politicians, but that doesn't mean I should believe them. "Solving the problem might take a LOT of prayer. " Indeed. It seems the prayers a good fraction of the population of Haiti http://en.wikipedia.org/wiki/Religion_in_Haiti couldn't steer a earthquake out of the way http://en.wikipedia.org/wiki/2010_Haiti_earthquake So the likelihood of all the prayers from this site achieving much is nearly nil. Feel free to prove me wrong by praying for me to win the lottery this week. This reminds me of the story told by Emo Philips. "when I was a Kid I used to pray that God would give me a bicycle. Then I realised He didn't work that way. So I stole bike and prayed for forgiveness."
