(According to Rav Weiss, the Yerushalmi holds – followed by Rambam– that any >important accomplishment of purpose has to be melachah, even if it does not seem to fall into one of the categories in Perek Klal Gadol. It will perforce be subsumed by the >melachah of makeh >bepatish.)<o:p></o:p></span></p><p><span lang=EN-GB style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\<o:p></o:p></span></p><p><span lang=EN-GB style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>JIR-WADR as I posted there- I have heard R’ Weiss mention this more than once and he has always said that based on that Yerushalmi anything that chazal thought shouldn’t be done on Shabbat and did not fit into one of the other 39 mlachot, would be forbidden as maakeh bpatish. Very subjective but that’s the way halacha is sometimes (as in another favourite of r’ Weiss – masruha lchachamim [and libi omer li])<o:p></o:p></span></p><p class=MsoNormal style='background:white'><span lang=EN-GB style='color:#1F497D'>//////////////////////////////////////////////////<o:p></o:p></span></p><p class=MsoNormal style='background:white'><span lang=EN-GB>And I responded to this section with a PS that read:<o:p></o:p></span></p><p><span lang=EN-GB style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>PS quantum mechanics actually says that you never really have a psik resha, it is only Newtonian mechanics that leads you to the conclusion set out here that there is always a psik resha since you could always determine if or if not a furrow would be made if you investigated the physics properly. However, since quantum mechanics is understood to reduce to Newtonian mechanics on the large scales we are talking about, eg making a furrow, (ie it becomes so statistically unlikely that the uncertainty of quantum mechanics will have an effect on the furrow that it can safely be ignored) I don’t suppose it matters in that context. This is not true, however, on the electron level where quantum mechanics plays a big part in semiconductor analysis, which I suspect is at the heart of many of the modern devices being discussed. Is this dicotomy taken into account?<o:p></o:p></span></p><p><span lang=EN-GB style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='margin-bottom:12.0pt;background:white'><span lang=EN-GB style='color:#1F497D'>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:12.0pt;background:white'><span lang=EN-GB style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>JIR-R’ Nissan Kaplan has a whole thing on why new refrigerators are a problem because of the continuous information transfer in the solid state thermostat that tells the refrigerator compressor what to do.
