New Scientist March 2005 Well worth a read. Interesting in their own right and sharing a common lesson, 13 observed phenomena that appear to be real and that appear to contradict relevant scientific "received truth". http://space.newscientist.com/article.ns?id=mg18524911.600 Includes placebo effect (specific interesting cases), dark matter / energy, changing physical "constants", incoming cosmic rays which (impossibly") exceed the GZK energy limit, tetraneutrons, unidentifiable force affecting Pioneer spacecraft trajectories, the Kuiper cliff - but, where is planet X, cold fusion is back AND respectable to the point of being DOD fundable, ... . Apart from their interest for their own sakes many of these are of interest for the light they throw on what we know, what we find we don't know, how we decide what we think we know and similar. Applying the lessons from these disciplines to other areas of 'science' where dogma rules supreme and thinking is essentially forbidden could be valuable. "*KNOWING* that we know" in any area, when, of course, we don't, has been shown time and again to be a sure way of not growing in knowledge. It still seems to happen though :-).
