It seems so. http://www.ibiblio.org/weidai/Many_Minds.pdf http://www.ibiblio.org/weidai/Many_Minds_Replies.pdf Each interpretation has problems (preferred basis, decoherence, recoherence, Born rule, etc.). I think here we are somehow mixing the two interpretation .... s. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
