  1. Re:Oh well. on Is Climate Change the New Evolution? · · Score: 1

    The word 'catastrophic' is not a scientific one. What science can provide you with is an estimation for temperatures and uncertainties. If the predicted uncertainties are smaller than the deviation from the measured, then the specific model is falsified.

    The hypothesis that climate would constant when considering a *specific* animal (e.g. humans) to be *not natural* is easily falsified, if you like to make this hypothesis (although nobody who is knowledged would make such a hypothesis).

  2. Oh well. on Is Climate Change the New Evolution? · · Score: 1

    Indeed Evolution and Climate change have a few things in common:

    a) Both are inconvenient for people who feel a certain kind of entitlement.

    b) Both are non-trivial to understand and difficult to predict in practice

    c) Both have been grossly exaggerated in the strength and speed of the effects in popular science. (climate change *will not cause a big tidal wave washing away harbour towns*, most likely climate change will *not* be observable definitely within a single human life and evolution will *not* change a species under natural conditions within the lifetime of a single person)

    so do these three point make them anyhow weaker theories? Not really.

    Lets compare the alternatives: creationism (no falsifiable, therefore no scientific theories) and climate change denial (falsified on every level). so should we teach them in science classes? no, we should not.

    What should we teach: be sceptical, especially if somebody tries to scare you with some *seemingly* scientific fact. When people talk about a glacier melting, try to put in the number and *see* if the change in the melting rate is really so bad. But then also estimate for the next hundred years. Be sceptical if explanations are too pleasant (like, don't change you convenient, wasteful lifestyle, you are the image of god).

    So the reason for speeding up the publication in 2002 by skipping a part of the normal review process was because they had a bias *against* the subject. Very convincing argument......

    You really want to tell me that Science and Nature, the most prestigeous journals for physicists, accepting each one seemingly groundbreaking paper paper, the latter one in 2002 *despite* the big embarassment of 89, is an indication of exclusion of the subject from scientific Journals?

    I am not wasting my time with material outside my field which has passed a single peer-review.

    preprints are not articles. I personally would propose that arxiv removes (respectively marks) everything which was not published as an article at most 3 years after submission there.

    I agree. The most comprehensive document i found using the search lenr on the NASA webpage on the research there seems to be:

    http://www.grc.nasa.gov/WWW/sensors/PhySen/docs/LENR_at_GRC_2011.pdf

    It is an obviously very optimistic document on why NASA should fund cold fusion research. And let me - as somebody who was a scientist for 10 years - clearly state that you viewpoint should be an optimistic one, when presenting in terms of "why is that fundamentally interesting". However, you should have a realistic opinion on "what needs to be done to verify the effect" *before* promising fancy devices.

    these are the references cited in the presentation above, which are not conference presentations, progress reports, or books, but real peer-reviewed papers:

    Kim, Y. E., âoeTheory of Bose-Einstein Condensation for Deuteron-Induced Nuclear reactions in Micro/Nano-Scale Metal Grains and Particlesâ, Naturwissenschaften 96, 803(2009).

    Let me say that very clearly: i am not an expert on the field. But if there would be anything which seems close to being implemented to people working in the field, then i know there would be several high-ranking papers.

    what makes me *particularly* (i am an experimentalist) doubt about this research, and especially Rossi (who claims incredible rates of conversion of the material) is that it should be extremely easy to detect the helium or other products (in Rossis case) in the output. The order of magnitude of the effects cited would be *massive* and easily detectable by the signature of the reactions in the waste products. Instead of looking at the reactors, i claim it would be better to examine the material input and output.

    Show me the peaks in am AMS, (if needed for efficiency, please use an acceleration mass spectrometer) for the fresh fuels and the spent fuel, and i believe in Cold fusion. Show me nice pictures and make a fence several meters around your device and don't publish in peer-reviewed journals and you will trigger my scepticism.

    However, if the cow is always close to getting a bacterial infection prevented by antibiotics then you have done something as wrong as if vegetables would rot in to moist ground and your solution to this would not be to regulate the amount of water but to hope to kill the bacteria in some other way.

    The point is: modern farming should provide ideal nutrition and environments to plant and animals - e.g. the hygienic greenhouses. If you do that then plants or animals don't get sick.
