ersatz [ˈɛrzɑts, -sɑts, ɛrˈzɑts, -ˈsɑts] a.
1.) Being an imitation or a substitute, usually an inferior one; artificial: e.g. ersatz coffee made mostly of chicory (American Heritage Dictionary of the English Language).
Etymology: German, replacement, from ersetzen, to replace, from Old High German irsezzan : ir-, out + sezzan, to set.
"If we look to physics to tell us what is possible, will we get all possible worlds? Or only the physically possible worlds, according to current physics? More, at least, than the latter. We will certainly construct ersatz worlds that disobey currently accepted physical laws; for instance, ersatz worlds where mass-energy is not conserved. Still, we cannot be sure of getting all possible worlds, since we cannot be sure that we have constructed our ersatz worlds at a high enough level of generality" (Counterfactuals, David K. Lewis, 1973).
Today's word in honor of Endless and my other German-speaking readers. Didn't want you guys to think I was only doing words of French and Latin origin. Also, looking at my stats, I see that I have some readers from Spain. Would love to hear from you. Any preference in the big Barcelona–Real Madrid showdown?
