    Agreed. My problem is that you seem to place too much trust in the
    proposition that you have suceeded; you trust yourself too much.
    I don't find any inconsistency in your means to achieve the result you
    are striving for; I just worry about the level of quality control that
    lets you be so optimistic about the results you claim to have
    achieved.
    Clearly too sane for my own good.

    What a skewed reality. You accept interpretation and
    manipulation of data you've never seen from people you
    don't know without reservation, yet dismiss a real guy's
    reliability experience with years of quality product he's
    delivered to the world's most demanding customers.

    That's bizarre.

    The data I'm accepting has passed through peer-review and is cross-
    checked against the work of other scientists that also goes through
    peer-review.

    John Larkin's claims about his gear don't have the same kind of built-
    in quality control. He may be selling to the world's most demanding
    customers - as was Cambridge Instruments back in the 1980's when I
    worked for them - but my opression is that these customers are mainly
    interested in getting hold of gear that they can use to solve their
    immediate problems; if it works, they aren't all that interested in
    how well it works.

    At Cambridge Instrumnents I did quite a lot of work on the EBMF 10.5
    electron-beam microfabricator, which is an extensively modified
    electron microscope which uses an electron beam to write fine patterns
    on a flat surface - usually a chromium mask to be used to define a
    layer in an integrated circuit.

    It was a fine machine and worked well for a lot of customers - the
    first one went to Fairchild with a set of scanning boards that I'd
    hand-modified, and they loved it and used it to make most of the masks
    for their 100k ECL parts.

    The European university's semiconductor lab at IMEC in Belgium bought
    one and set a bunch of graduate students to characterising the machine
    while they got their semiconductor fab up and running, and they found
    more minor faults than you could shake a stick at. At one point the
    engineers who were working on correcting these faults came to me to
    get hold the heat-pipe based heat-sink from my cupboard that I'd
    ordered and not been given the time to try out on the machine - the
    problem it was intended to solve was hypothetical and the guys at IMEC
    had taken the trouble to validate my hypothesis.

    Quality control on complex machines takes a lot of work and few
    organisations have got the time to do it.

    I know stuff. Graham doesn't and he really doesn't appreciate how
    little he knows and how much there is to know.This makes it difficult
    for him to understand what I'm on about.

    From my point of view, it is Graham's pretensions to knowledge that
    are really bizarre. It is as if he aspired to compete in formula one
    riding a unicycle.

    Like Mann's ?

    You talk a lot.

    I've never seen you make a single decent design suggestion. Speaks volumes.

    You ARE indeed quite MAD. It's time you sought treatment. Your detachment from
    reality accelerates every single day.

    By your own admission, the data are not reviewed.
    That is a baseless slander.

    All I had to do was read your reply James at the botton of the page, to KNOW it
    was a post of Sloman's. What is the matter with the man ?

    He just jumps to conclusions, that's all. He knows America
    better than Americans, from his sources overseas, John's
    business better than John, etc. And then he sticks to his
    unloaded guns and lectures us.

    I've seen John's gear. It's good.

    Cheers,

    The most reliable sign of sanity is doing the same thing while expecting
    different results.

    This is something you misunderstand. It's not optimism at all - it's
    something called confidence, that comes from doing it right the first
    time, by distrusting everything along the way - you don't sign off on
    the component or subassembly until you can _demonstrate_ that it meets
    or exceeds the spec.

    Cheers!

    Possibly. But I've got a long way to go before I'm as detached as the
    average psychiatrist, let alone you or Jim Thompson, and I'd have to
    be much further out of touch with reality than I am now to be silly
    enough to consider taking your advice.

    Graham is indulging in the fallacy of the excluded middle. Her seems
    to think that because one academic paper was inadequately refereed, no
    academic paper is to be trusted, and - in a sense - he is right.

    I've published a couple of comments in Review of Scientific
    Instruments and a couple of other peer-reviewed journals pointing out
    that specific papers are inadequate, which is another aspect of the
    academic quality control system.

    This doesn't mean that one discards every paper ever published as
    unreliable - the bulk of the published papers on anthropogenic global
    warming form a coherent and self-consistent mass of evidence
    supporting the hypothesis.

    Graham doesn't know enough about science to understand this, and
    nowhere near enough about the science involved to read any of the
    papers and understand the evidence for himself, but he is too much of
    a conceited know-it-all to believe this.

    Some residual contact with reality? I'm not less scpetical about John
    Larkin's fantasies tha I am about yours?

    I do seem to be free of certain delusions Americans have about the
    perfection of their electoral system and their health care systems; I
    imagine I'm less exposed to the domestic propaganda machine which
    starts telling Americans that America is perfect as soon as they get
    into the education system, and reinforces the message through the mass
    media for the rest of their lives.
    John Larkin does seem to think that anybody expressing an opinion on
    his business is - ipso facto - claiming to know it better than he
    does, which is rather silly.
    It's for your own good.
    Of course it is good, but mind-rippingly good, insanely priced,
    perfect-out-the-door good?

    Some scepticism is obligatory.
     
  18. Guest

    We've all got that, mostly with good reason. Even so, the evidence
    suggests that nobody gets everything right, every time.
     
  19. Guest

    That's not what I said and its also quite untrue. The papers the IPCC
    survey and report on are peer-reviewed before they get into the
    published literature, and the IPCC's reporting process shows up
    conflicting conclusions (which is the second string of the scientific
    quality control process).
    There's nothing slanderous about it. There's no control of any sort on
    what he posts here. In any event "mind-rippingly good, insanely
    priced, perfect-out-the-door" aren't the sort of claims that you could
    usefully test in a court of law.

    Then you haven't been paying attention - which isn't unexpected.
