  1. I'm not convinced that the best answer to the original question involves all the spinoffs.

    Surely it is like asking "Art; why bother?" and the answer is that it's what humans do.

    On the other hand, my favorite example is that particle physics like atom smashing makes lots of data and that some bloke at CERN wanted a way of sending lots of data round the place.

    There's a reference to it in that page ajb cited. The outcome was called the web.

  2. Can you link me to a write-up or describe the procedure for me? Really? bunsens get that got? i thought they managed about 700°C tops.

     

    Well, if you put fine copper wire in a candle flame it melts so that's over 1083C.

     

    Anyway, here's a demo.

    It's called "Reduction of Copper Oxide"- not very original.

     

    BTW, don't do thermite reactions in test tubes there's far too big a risk of flying glass.

  3. "There is no need to account for, or explain; those things that QT already does very well."

    Yes there is, it's called producing a consistent theory. If your theory can't explain simple things then it's no use trying to get it to explain complex ones.

    "There is a need to explain those things that QT does not do."

    OK, but your theory hasn't done this. Is it any use at all?

  4. I always thought that the answer to "Okay, say someone would be an alcoholic, and destroys alot of brain cells. How long would it take for the brain to regenerate cells? " was "Do you believe in reincarnation?" because you won't regenerate any to speak of in this lifetime.

  5. Those costs are a bit absurd. There's no reason you can't do everything with a kitchen freezer and a $100 microscope, especially considering Emoto's "always" and "never" claims. In fact, if that were true, you probably wouldn't even need the microscope.

     

    Actually, I think that some people could do it more cheaply still.

    What we need is someoone with a working understanding of Japanese and a copy of the Tokyo yellow pages.

    Phone any of the plumbers and ask them if they have ever had to repair a pipe that burst when it froze.

    If they have, then we know that Tokyo tap water freezes (at least once) asd we can dismiss Emoto's ideas completely.

     

    Roughly equivalently, we can seek to find out if this sort of product

    http://www.plumbworld.co.uk/arctic-spray-2-high-0-3509?CAWELAID=205025317

    is on sale there.

     

    Sometimes, you don't need Galileo or Columbus- you just need a Japanese plumber.

  6. "I imagine that many people expressed much the same sentiment when Galileo tried to make the case for a round earth.

     

    I hope you will further refine your objections to fit more comfortably within the framework of a reasonable discussion."

    An appeal to authority like that is a logical fallacy. It doesn't fit within the framework of a reasonable discussion.

     

    Anyway, I find both sets of crystals (from the tap water) beautiful, so there's no case to answer.

     

    There is also the assertion that the water will "never form crystals".

    Never is a long time; it is not reasonable to extrapolate infinitely into the future on the basis of a very limited set of results (ie one dodgy result).

    Do pipes freeze and burst in Tokyo?

    If they do then that proves the assertion to be false.

    Also, do you have the xray and neutron diffraction patterns from the two frozen samples. If you compare them and find them to be significantly different then you may have a valid point; until then you have baseless speculation.

  7. is it too late to plead the 5`th?

     

    Do you mean the 5th ammendment to the constitution of a country that has no jurisdiction where you are?

     

    You do not have to say anything

    But it may harm your defence if you do not mention,

    when questioned something which you later rely on in court.

    Anything you do say may be given in evidence

  8. Very kind of you vedmecum, to try to bail me out but I screwed up.

    I knew it did both forms of decay (which is why I said "mainly- but lets ignore the other possibility for a minute") but I got the decay mixed up.

  9. This isn't the only forum on which someone is franticaly trying to plug that product.Also I don't see any evidence for the claim that yellow light is bad for your eyes or, come to that, that CFLs generate a lot of yellow light.

    The only CFLs that I have looked at through a spectroscope emit little or no yellow light - they rely on red and green emisions (together with blue of course) to produce light that looks white.

    So, overall, it seems to me that this is not just a spam advert, but a dishonest one.

  10. Let's take an odd example, but one where the chemistry is relatively simple.

    Potassium has a naturally ocurring isotope of mass 40 which decays (mainly- but lets ignore the other possibility for a minute) by beta decay to give argon. It has a half life of 1.25 billion years I think)

     

    Imagine that we extract some of this isotope of potassium and turn it into the chloride.

     

    It decays slowly but surely to argon, and of course, argon doesn't form a chloride.

     

    So the reaction is

    2 KCl --> 2Ar +Cl2.

    The potassium was there as K+ ions and when they lost a beta particle they (briefly) became Ar++ ions.

    Now Ar(II) is a much stronger oxidant that you get in any normal sort of chemistry. It's perfectly capable of oxidising chloride to chlorine.

     

    In case you are wondering, the beta particle will hit something and stop. Then it's just an electron. Now tha electron (on it's own) is a very powerful reducing agent. It can certainly reduce Ar+ to Ar

  11. Since when? You're missing a vast amount of chemistry somewhere.

     

     

     

    That sounds exceedingly dated. I suspect the main component is sodium amide.

     

    That's an interesting concept.

    Electrolysis of a solution of ammonium chloride in water giving a sodium compound.

    Here's a relatively recent reference to a related compound, just to spice things up a bit.

  12. Just saw open a small battery (preferably new, AA is great) it will contain zinc, MnO2, and some slippery KOH will spew out (I suggest you wear gloves)...

    QUOTE]

    Gloves are probably a good idea but I'd say safety glasses/ goggles are more important.

     

    Anyway, while it's true that you can use all sorts of things to decompose H2O2, I suspect that yeast will be one of the easiest to write a risk assessment for.

    Platinum's expensive; liver (unless it's food grade) is probably listed as a biohazard; the water treatment people don't like much copper in waste streams, and manganese is neurotoxic.

     

    Lord knows what the green colour was- presumably an impurity from somewhere.

  13. I'm not sure this "When two people of differing skin colour have offspring, the kids will have uniform skin colour and also their hair is of uniform consistency." is strictly true.

    I'm sure there are pairs of siblings who are differeent colours because they happened to get a different mix of genes from their parents.

    Also, skin colour isn't generally identical across the whole body; at the very least you have to accept that dark skinned people's palms are generally paler than the rest of them.

     

    Anyway, to the extent that it is true (and to a fair degreee it is) I think the simple answer is that in any one body there's generally only one set of genes and your skin is the colour that that set codes for. Same with hair. The relation between genes and colour is complicated but if there's only 1 set of genes then there's only one colur.
