The last was a little joke, of course. But all I mean to point to is that what we call "physics", "chemistry", "biology", ... and then we put the words "laws of" in from of those words, are completely human-made. There is nature, or the cosmos as Carl Sagan put it (I would posit) but our "theories" of it are things we manufacture. There is no Platonic Heaven where the "laws of" came down from. There may be a new science 100 years from now. Who knows? - pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
