RE: Homeopathy: Just water?
Invoking Nobel Prize names does not help the argument if you really want to discuss science. Quite often there has been the case of Nobel Prize winners to be good in one area of research and completely off track in others (i.e., Linus Pauling, Luc Montagnier, and others). Appealing to authority for the sake of making it appear they are 'gods' is misleading.
To me it cannot more clear that homeopathy is the purest of non-sense. Of course, I leave room for being proven otherwise, but that's like less than 0.0001% - which I think is a good argument in the context of homeobs :)
